It uses a line-laser, a webcam and the DAVID software to &#8216;read&#8217; the depth information of a scene. Once you&#8217;ve made multiple scans of an object, it can stitch them together to get a to get a full 360 degree scan.<\/div>\n<div><\/div>\n<div>The cool thing is that you can use the basic DAVID scanning software for free (albeit limited in resolution). The stitching software (&#8216;Shape Fusion&#8217;), though, is commercial and is included in the professional version of the software which starts at &euro; 199,-. So if you have a decent webcam and a line-laser (which you can buy starting at &euro; 19,- in the DAVID shop), you can start experimenting with 3D scanning on a *really* tight budget.<\/div>\n<div><\/div>\n<div>\n<ul>\n<li><!-- s9ymdb:586 --><a target=\"_blank\" href=\"https:\/\/www.shapeways.com\/blog\/wp-content\/uploads\/2009\/06\/david-starter-kit-small2.jpg\" class=\"serendipity_image_link\"><!-- s9ymdb:588 --><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"200\" src=\"https:\/\/www.shapeways.com\/blog\/wp-content\/uploads\/2009\/06\/david-starter-kit-small2.jpg\" style=\"border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; border-top-style: none; border-right-style: none; border-bottom-style: none; border-left-style: none; border-color: initial; float: right; padding-left: 5px; padding-right: 5px; \"><\/a>I was curious to see how well this worked and if the scanned models would work with Shapeways, and requested a DAVID starter kit for review. This kit sells for &euro;399 on their website, and contains everything you need to scan and stitch your objects:<\/li>\n<li>Several calibration panels (for different scan sizes).<\/li>\n<li>A red line laser, battery operated with adjustable focus.<\/li>\n<li>QuickCam Pro9000 1600&#215;1200 webcam including a stand.<\/li>\n<li>A USB Stick with software.<\/li>\n<li>An extensive manual.<\/li>\n<li>Monkey not included \ud83d\ude09<\/li>\n<\/ul>\n<\/div>\n<p><!--more--><\/p>\n<div><b>Getting started<\/b><\/div>\n<div>Installation was easy enough if you follow the manual step by step. The main things to do are to install the webcam drivers, and install .NET 2.0 if you haven&#8217;t already. The software itself runs off the USB key (which functions as copy protection) and requires no installation.<\/div>\n<div><\/div>\n<div>The manual I received was in German by the way but I&#8217;m sure that was just a mistake. I *was* a bit disappointed though that only after my tests I found out about their excellent on-line manual that contains much better information than the printed version! (You&#8217;ll find the link at the end of this article).<\/div>\n<div><b><br \/>Mac users<\/b><\/div>\n<div>I immediately ran into a snag: the DAVID software is Windows-only and I&#8217;m a Mac user. Fortunately I can run Windows under VMWare Fusion which did a great job in recognizing the webcam and USB key. The performance was acceptable on a MacBook Pro, although my system wasn&#8217;t powerful enough to use the camera at the highest resolution of 1600&#215;1200 pixels at a reasonable speed. Therefore, the resolution of my scan is probably not the optimal result that you can achieve with DAVID.<\/div>\n<div><\/div>\n<div><b><br \/>Calibrating the system<\/b><\/div>\n<div><!-- s9ymdb:585 --><a class=\"serendipity_image_link\" href=\"https:\/\/www.shapeways.com\/blog\/wp-content\/uploads\/2009\/06\/screenshot_software_calib-small2.jpg\" target=\"_blank\"><!-- s9ymdb:589 --><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"386\" style=\"border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; border-top-style: none; border-right-style: none; border-bottom-style: none; border-left-style: none; border-color: initial; float: right; padding-left: 5px; padding-right: 5px; \" src=\"https:\/\/www.shapeways.com\/blog\/wp-content\/uploads\/2009\/06\/screenshot_software_calib-small2.jpg\"><\/a>Before you can start scanning, you&#8217;ll have to teach the software about the environment you&#8217;re using. This is easy as it&#8217;s all done automatically during the &#8216;calibration&#8217; process. &nbsp;First choose the correct calibration panel; there are three panels for different scan sizes. Use the one that matches the size of the object you want to scan.<\/div>\n<div><\/div>\n<div>Now start the calibration and everything will be taken care of. I did find that during my initial tests the system had trouble to calibrate correctly, but the manual explained how to fix this using some manual corrections on the calibration image.<\/div>\n<div><\/div>\n<div>The system now knows all it needs to know about the lens and the setup to create &#8216;absolute scale&#8217; models.<\/div>\n<div><\/div>\n<div>After the software is calibrated, do not touch the camera or calibration panels anymore! If you do, you&#8217;ll have to start all over.<\/div>\n<div><\/div>\n<div><b><br \/>Tip<\/b>: If you don&#8217;t have calibration panels, you can <a target=\"_blank\" href=\"http:\/\/www.david-laserscanner.com\/wiki\/user_manual\/getting_started\">make them yourself<\/a>!<\/div>\n<div><\/div>\n<div><b><br \/>Running the scan<\/b><\/div>\n<div>Scanning is easy but time consuming: you &#8216;brush&#8217; over your object with the laser line. At the same time you see the contour lines appear on the screen, and you can keep going until you feel that you&#8217;ve scanned in enough points to get an accurate render of your object.&nbsp;<\/div>\n<div>Once you&#8217;re happy with the result you save the scan, rotate the object by 45 or 90 degrees and repeat.&nbsp;<\/div>\n<div>I found that creating a good scan takes about 5 minutes per step &ndash; I&#8217;m guessing that on a faster computer this might be a bit less as it would be easier to accurately scan small details.<\/div>\n<div><\/div>\n<div><a class=\"serendipity_image_link\" href=\"\/blog\/uploads\/scan-montage-blog.jpg\"><!-- s9ymdb:581 --><\/a><a class=\"serendipity_image_link\" href=\"\/blog\/uploads\/scan-montage-blog.jpg\"><!-- s9ymdb:581 --><\/a><\/div>\n<div><a href=\"https:\/\/www.shapeways.com\/blog\/wp-content\/uploads\/2009\/06\/scan-montage-blog2.jpg\" class=\"serendipity_image_link\"><!-- s9ymdb:581 --><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"314\" src=\"https:\/\/www.shapeways.com\/blog\/wp-content\/uploads\/2009\/06\/scan-montage-blog2.jpg\" style=\"border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; border-top-style: none; border-right-style: none; border-bottom-style: none; border-left-style: none; border-color: initial; padding-left: 5px; padding-right: 5px; \"><\/a><br \/><a class=\"serendipity_image_link\" href=\"\/blog\/uploads\/scan-montage-blog.jpg\"><\/a><\/div>\n<div><\/div>\n<div><b><br \/>Stitching the scans<\/b><\/div>\n<div>During the stitching phase you align the separate 3D scans. Again, the software is quite clever. Most of the time, you&#8217;ll only need to select two scans and watch the software move them about until they match (this is a lot of fun to watch, actually!). &nbsp;<\/div>\n<div>After alignment, the object still looks messy: it has some outliers and holes in them. This is where the &#8216;Fuse&#8217; step comes in: it&#8217;ll smooth the surface of your object and close all the hole in the surface. And here&#8217;s where the REALLY good news comes in: *Fuse creates watertight or manifold objects!* Yes, you can upload these models straight to Shapeways!

There you have it. And I&#8217;ve seriously considered NOT to return my review unit to DAVID \ud83d\ude09<\/div>\n<div>Having said that: don&#8217;t expect a magic wand: scanning your object takes serious time and effort. You&#8217;ll be spending a LOT of time in a dark room tweaking the settings and laboriously sweeping a laser-beam over your objects. After a while it&#8217;ll get easier though and you&#8217;ll get a feeling for how to set everything up. The scanner won&#8217;t be able to scan every object to throw at it: highly reflective or transparent objects are difficult, but you can solve that by spraypainting or powdering them.<\/div>\n<div>I also found the software a bit on the technical side and not as user-friendly as it could be. It gets the job done rather well though, so this is not too much of an issue.<\/div>\n<div><\/div>\n<div><\/div>\n<div><b><br \/>Did I feel that the DAVID Starter Kit is good value for money?<\/b><\/div>\n<div>Receiving all the required equipment is very convenient (especially for busy people like me), and I especially appreciated the ready-to-use calibration panels. If you want to save yourself some money you can print these out yourself though and buy a cheap webcam and focusing line laser on the web &ndash; that would probably shave off about &euro; 100,- of the total kit price.&nbsp;<\/div>\n<div>The scanned result was impressive enough and I&#8217;m sure it could be further improved with more practice and a computer that could actually use the high resolution of the webcam.<\/div>\n<div>Count in Shape Fusion&#8217;s ability to generate ready-to-print models for Shapeways and I&#8217;d say this is a definitive must-have for designers who are into 3D printing.<\/div>\n<div><b><br \/>Related links<\/b><\/div>\n<div><\/div>\n<ul>\n<li><a target=\"_blank\" href=\"http:\/\/www.david-laserscanner.com\">DAVID Website<\/a><\/li>\n<li><a target=\"_blank\" href=\"http:\/\/www.david-laserscanner.com\/?section=Downloads\">Downloads<\/a><\/li>\n<li><a target=\"_blank\" href=\"http:\/\/www.david-laserscanner.com\/wiki\/user_manual\/getting_started\">Manual<\/a><\/li>\n<li><a target=\"_blank\" href=\"http:\/\/www.david-laserscanner.com\/wiki\/david_laserscanner_multimedia_gallery\">User Galleries<\/a><\/li>\n<li><a target=\"_blank\" href=\"http:\/\/www.david-laserscanner.com\/?section=Buy\">Professional licenses<\/a><\/li>\n<li><a target=\"_blank\" href=\"http:\/\/www.david-laserscanner.com\/?section=Starter-Kit\">Starter Kit<\/a><\/li>\n<li><a target=\"_blank\" href=\"http:\/\/shop.david-vision-systems.de\/index.php\/language\/en\">Shop (for lasers etc)<\/a><\/li>\n<\/ul>\n<div><\/div>\n<div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>The DAVID 3D scanner is do-it-yourself 3d scanning kit.
