My name is Lassi Kaukonen and I come from the former capital city of Finland called Turku. I am an old school gamer from the early 80\u2019s and my training in 3D has been self-taught. I have always been a very tech-savvy person and I have a pretty good knowledge of photography. I work in the hospital district of southwest Finland as a system specialist and currently I\u2019m working on a project that aims to ease people\u2019s navigation within the hospital and its surroundings via photogrammetry and other things. My passion for photogrammetry started about three years ago when I managed to scan things from my backyard and place them in a virtual environment that I had created in Unity. My desire to make better models grew stronger last year when I had the chance to create a virtual environment for psychiatric healthcare. The goal was to make a VR app to help people with performance anxiety.<\/p>\n<h2>Circumstances<\/h2>\n<p>I stumbled upon this specific live orchid flower in IKEA. I was waiting for my wife and noticed a bunch of orchids on a stand. I remembered the countless hours that I had spent in my basement last summer and autumn trying to make models from leaves and decided to scan one of these beautiful and well-patterned flowers.<\/p>\n<div class=\"sketchfab-embed-wrapper\">\n                        <iframe src=\"https:\/\/sketchfab.com\/models\/9fccecce83c14937a1936d915825efd9\/embed\"  width=\"690\" height=\"388\" frameborder=\"0\"><\/iframe>\n                    <\/div>\n                        <div class=\"sf_caption\">These are the birch leaves that I scanned last summer\/autumn.<\/div>\n<h2>Inspiration<\/h2>\n<p>My inspiration for this model came from the thought that I could learn something by scanning it. I could compare the results between those leaves I scanned back in summer and maybe find new pointers or methods that I could use when scanning something challenging.<\/p>\n<div class=\"sketchfab-embed-wrapper\">\n                        <iframe src=\"https:\/\/sketchfab.com\/models\/ce70647af1cf4e1d91c0c1d576459c37\/embed\"  width=\"690\" height=\"388\" frameborder=\"0\"><\/iframe>\n                    <\/div>\n                        <div class=\"sf_caption\">And these are European aspen leaves from the same experiment.<\/div>\n<h2>Taking Pictures<\/h2>\n<p>I do most of my scans indoors with a tripod and the subject on a turntable. This is because you can control things like light and background easily. This orchid flower was shot on a turntable, but I did not take the shots in my usual place because my usual shooting space was under renovations.<\/p>\n<p>I took the photos in front of a cabinet with a Nikon D5300 + 40mm Micro Nikkor, ISO 100, F\/22, Kenko circular polarization filter, and a remote. The remote is a very handy tool to have and I noticed that without it the camera tends to shake or move even on a tripod.<\/p>\n<p>For light, I used an F&amp;V R-300 ring light that I polarized with a linear polarizing film placed over the light source. This method of using two polarizing elements (one for the light and one for the lens) is called cross-polarization and with it, you can eliminate specular highlights and leave only the diffused component. I learned about this technique from this <a href=\"https:\/\/www.youtube.com\/channel\/UC-vjwF8f5_036zKWLs5vEyg\" target=\"_blank\" rel=\"nofollow\">YouTube channel<\/a>. This gentleman has absolutely amazing photogrammetry tutorials with great entertainment value.<\/p>\n<div id=\"attachment_142059993076\" style=\"width: 2009px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image11-2.jpg\"><img decoding=\"async\" aria-describedby=\"caption-attachment-142059993076\" class=\"size-full wp-image-142059993076 lazyload\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image11-2.jpg\" alt=\"photogrammetry equipment\" width=\"1999\" height=\"1500\" \/><p id=\"caption-attachment-142059993076\" class=\"wp-caption-text\"><noscript><img decoding=\"async\" class=\"size-full wp-image-142059993076 lazyload\" src=\"https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image11-2.jpg\" alt=\"photogrammetry equipment\" width=\"1999\" height=\"1500\" srcset=\"https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image11-2.jpg 1999w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image11-2-300x225.jpg 300w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image11-2-1030x773.jpg 1030w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image11-2-768x576.jpg 768w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image11-2-80x60.jpg 80w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image11-2-1536x1153.jpg 1536w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image11-2-666x500.jpg 666w\" sizes=\"(max-width: 1999px) 100vw, 1999px\" \/><\/noscript><\/a> Equipment I used during this scan<\/p><\/div>\n<p>I had learned from scanning leaves that I would need to take more pictures than usual (with an easy subject, I take about 40 pictures per round and with thin subjects like leaves, coins, and petals I take about 80\u2013120). The next thing was to have a shooting angle that I could shoot the largest part of the thinnest area head-on and capture the whole subject with one round. I have never managed to align more than one set of pictures when dealing with leaves but, for example, with coins, you can align two or three different sets pretty easily. Lastly, I would need to remove the specular highlights for the alignment to be successful and this I could achieve with cross-polarization.<\/p>\n<div id=\"attachment_142059993075\" style=\"width: 2009px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image10-3.jpg\"><img decoding=\"async\" aria-describedby=\"caption-attachment-142059993075\" class=\"size-full wp-image-142059993075 lazyload\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image10-3.jpg\" alt=\"photogrammetry difficult subject\" width=\"1999\" height=\"1333\" \/><p id=\"caption-attachment-142059993075\" class=\"wp-caption-text\"><noscript><img decoding=\"async\" class=\"size-full wp-image-142059993075 lazyload\" src=\"https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image10-3.jpg\" alt=\"photogrammetry difficult subject\" width=\"1999\" height=\"1333\" srcset=\"https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image10-3.jpg 1999w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image10-3-300x200.jpg 300w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image10-3-1030x687.jpg 1030w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image10-3-768x512.jpg 768w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image10-3-1536x1024.jpg 1536w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image10-3-750x500.jpg 750w\" sizes=\"(max-width: 1999px) 100vw, 1999px\" \/><\/noscript><\/a> Sample from the photoset. Typical upper and lower angle were not needed as the \u201ceye-level\u201d covered the whole subject.<\/p><\/div>\n<p>The total number of pictures I took of the orchid was 101 + one from the background. That means I took photos in about 3-degree intervals, but this is a rough estimate because it was done by rotating the turntable by hand and with no markers.<\/p>\n<h2>The Hardware<\/h2>\n<p>In photogrammetry, it\u2019s useful to have powerful CPU+GPU and as I have a huge passion for games, this orchid was created with a self-built rig with Ryzen 3900x and RTX 2080Ti + 32gb of DDR4 3000mhz.<\/p>\n<h2>Agisoft Metashape<\/h2>\n<p>The most important thing when processing a scan that has been done with the \u201cturntable\u201d method is masking. I had to mask this orchid twice with different techniques because I took the photos in an unusual space. The cabinet behind the subject wasn\u2019t an ideal background so my mask (which I created from the background) was either taking part of the background with it or leaving a part of the model out. You can also mask in Metashape with the \u201ctie-point\u201d method\u2014where you mask the background and then align the photos\u2014but I did not want to use this method because I knew I had to probably align the photos on with the highest setting and the tie-point method would take ages with that.<\/p>\n<p>Now I had to make a choice between taking the pictures again with a green screen or trying to create proper masks some other way. So here is what I did. I created masks from background, aligned the photos with a little background attached to them, cleaned the background tie-points a bit, and built a medium dense cloud out of it. Then I quickly cleaned the background out of the dense cloud and created a mesh out of it. After I had the \u201csimplified\u201d mesh ready I created masks again based on the model. Now I had a pretty good mask for the model and I ran the alignment, dense cloud + mesh creation again.<\/p>\n\n\t\t<style type=\"text\/css\">\n\t\t\t#gallery-1 {\n\t\t\t\tmargin: auto;\n\t\t\t}\n\t\t\t#gallery-1 .gallery-item {\n\t\t\t\tfloat: left;\n\t\t\t\tmargin-top: 10px;\n\t\t\t\ttext-align: center;\n\t\t\t\twidth: 33%;\n\t\t\t}\n\t\t\t#gallery-1 img {\n\t\t\t\tborder: 2px solid #cfcfcf;\n\t\t\t}\n\t\t\t#gallery-1 .gallery-caption {\n\t\t\t\tmargin-left: 0;\n\t\t\t}\n\t\t\t\/* see gallery_shortcode() in wp-includes\/media.php *\/\n\t\t<\/style>\n\t\t<div id='gallery-1' class='gallery galleryid-142059993065 gallery-columns-3 gallery-size-full'><dl class='gallery-item'>\n\t\t\t<dt class='gallery-icon landscape'>\n\t\t\t\t<a href='https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image7-6.jpg'><img decoding=\"async\" width=\"1999\" height=\"1083\" src=\"https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image7-6.jpg\" class=\"attachment-full size-full\" alt=\"\" aria-describedby=\"gallery-1-142059993072\" srcset=\"https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image7-6.jpg 1999w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image7-6-300x163.jpg 300w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image7-6-1030x558.jpg 1030w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image7-6-768x416.jpg 768w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image7-6-1536x832.jpg 1536w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image7-6-370x200.jpg 370w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image7-6-740x400.jpg 740w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image7-6-923x500.jpg 923w\" sizes=\"(max-width: 1999px) 100vw, 1999px\" \/><\/a>\n\t\t\t<\/dt>\n\t\t\t\t<dd class='wp-caption-text gallery-caption' id='gallery-1-142059993072'>\n\t\t\t\tThis isn\u2019t good.

After this, I exported the model and took it back to Metashape for texturing.<\/p>\n<div id=\"attachment_142059993080\" style=\"width: 2009px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image2-5.jpg\"><img decoding=\"async\" aria-describedby=\"caption-attachment-142059993080\" class=\"size-full wp-image-142059993080 lazyload\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image2-5.jpg\" alt=\"\" width=\"1999\" height=\"1083\" \/><p id=\"caption-attachment-142059993080\" class=\"wp-caption-text\"><noscript><img decoding=\"async\" class=\"size-full wp-image-142059993080 lazyload\" src=\"https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image2-5.jpg\" alt=\"\" width=\"1999\" height=\"1083\" srcset=\"https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image2-5.jpg 1999w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image2-5-300x163.jpg 300w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image2-5-1030x558.jpg 1030w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image2-5-768x416.jpg 768w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image2-5-1536x832.jpg 1536w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image2-5-370x200.jpg 370w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image2-5-740x400.jpg 740w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image2-5-923x500.jpg 923w\" sizes=\"(max-width: 1999px) 100vw, 1999px\" \/><\/noscript><\/a> This is how the model mesh looked after a quick visit in Blender.<\/p><\/div>\n<h2>Texturing in Metashape<\/h2>\n<p>There are a few different ways I typically texture in Metashape, but with this one, it was very straightforward. I had pretty controlled conditions apart from a bad background, and all the specular highlights had been removed, so I textured the orchid with the mosaic setting and with all images in the photoset.<\/p>\n<p>I wanted to post a downloadable high-poly model of an orchid so I didn\u2019t need to bake any additional maps for this one.<\/p>\n<h2>New Thing I Learned<\/h2>\n<p>I learned a couple of new things from this project, but the most important thing I learned is that a distinctive pattern on a bendy thin surface can probably help with the construction in these kinds of situations when the alignment seems to be fine and the cloud of tie points look very good, but the dense cloud is creating some sort of noise that prevents the mesh from being properly built. (I had lots of these kinds of problems with maple leaves that I tried to scan back in those darkening autumn nights.)<\/p>\n\n\t\t<style type=\"text\/css\">\n\t\t\t#gallery-2 {\n\t\t\t\tmargin: auto;\n\t\t\t}\n\t\t\t#gallery-2 .gallery-item {\n\t\t\t\tfloat: left;\n\t\t\t\tmargin-top: 10px;\n\t\t\t\ttext-align: center;\n\t\t\t\twidth: 33%;\n\t\t\t}\n\t\t\t#gallery-2 img {\n\t\t\t\tborder: 2px solid #cfcfcf;\n\t\t\t}\n\t\t\t#gallery-2 .gallery-caption {\n\t\t\t\tmargin-left: 0;\n\t\t\t}\n\t\t\t\/* see gallery_shortcode() in wp-includes\/media.php *\/\n\t\t<\/style>\n\t\t<div id='gallery-2' class='gallery galleryid-142059993065 gallery-columns-3 gallery-size-full'><dl class='gallery-item'>\n\t\t\t<dt class='gallery-icon landscape'>\n\t\t\t\t<a href='https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image4-7.jpg'><img decoding=\"async\" width=\"1999\" height=\"1083\" src=\"https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image4-7.jpg\" class=\"attachment-full size-full\" alt=\"\" aria-describedby=\"gallery-2-142059993082\" srcset=\"https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image4-7.jpg 1999w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image4-7-300x163.jpg 300w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image4-7-1030x558.jpg 1030w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image4-7-768x416.jpg 768w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image4-7-1536x832.jpg 1536w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image4-7-370x200.jpg 370w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image4-7-740x400.jpg 740w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image4-7-923x500.jpg 923w\" sizes=\"(max-width: 1999px) 100vw, 1999px\" \/><\/a>\n\t\t\t<\/dt>\n\t\t\t\t<dd class='wp-caption-text gallery-caption' id='gallery-2-142059993082'>\n\t\t\t\tHere is a picture of the tie-points and alignment of a yellow maple leaf that seems good.\n\t\t\t\t<\/dd><\/dl><dl class='gallery-item'>\n\t\t\t<dt class='gallery-icon landscape'>\n\t\t\t\t<a href='https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image6-6.jpg'><img decoding=\"async\" width=\"1999\" height=\"1083\" src=\"https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image6-6.jpg\" class=\"attachment-full size-full\" alt=\"\" aria-describedby=\"gallery-2-142059993071\" srcset=\"https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image6-6.jpg 1999w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image6-6-300x163.jpg 300w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image6-6-1030x558.jpg 1030w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image6-6-768x416.jpg 768w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image6-6-1536x832.jpg 1536w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image6-6-370x200.jpg 370w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image6-6-740x400.jpg 740w, https:\/\/sketchfab.com\/blogs\/community\/wp-content\/uploads\/2020\/01\/image6-6-923x500.jpg 923w\" sizes=\"(max-width: 1999px) 100vw, 1999px\" \/><\/a>\n\t\t\t<\/dt>\n\t\t\t\t<dd class='wp-caption-text gallery-caption' id='gallery-2-142059993071'>\n\t\t\t\tThis is the dense cloud.
