Re: Tonights Scan project (Artec Eva Content :)

I friend of mine lent me an Artech Eva a week ago. And I've been using it with Scan Studio 12 for about a week now. Tonight I went to a friends studio and tried scanning a few of his sculptures. They range in size from about 1 sq meter to pieces that are the size small trucks. Here is a picture of ...

Re: Alignment problems

For me, the calibration checkered pattern is jagged and can't be jugged if it crosses the center of calibratiom circles. Using LG full hd tho, its smooth. Maybe its a good idea to print the center point in different color to get better idea of the calib precision. If your Projected Check Board is J...

Re: Alignment problems

Generally I can tell how good my alignment is by how well David displays the checkerboard after the calibration sequence. This is important feedback. The key is also looking at the alignment of the corners that are at the very periphery of the envelop. If they aren't perfect, Adjust the position of...

Re: Alignment problems

Hi. I've found something new and very useful for who has problems with alignment. I have same problem, but I'm sure it is because of Projector. I have a SHARP Projector. Never successful alignment with single camera (Over 1.5mm Deviation per 200mm object). But with dual camera it is reduced down to...

Re: Alignment problems

@3dxcan when you try and share the scan will leave place for discusion. 2scan in DAVID =10 scan in FLEX. It depends for what you want to judge!!! I know for markers tha help alignment in FLEX but didnt have time to test. If so share your scan data. @Micr0 Thanks! I will find time to post setup. I'm...

Re: Alignment problems

2 shots is too few to judge. Flexscan can utiluze markers for alignment. So instead of millions of points, it aligns using few number of target points. That's where the real benefit is.i'd try with a lsrge object and use target points.

Re: hdi advance flexible 3dscanner hardware positioning

Wow. Glad to hear someone is trying things other than david. Angle between 20 to 25 is ideal. Thats used in other scanners too. Flex shouldnt be an exception.

Re: Alignment problems

I think that ONE of the most important case for good alignment is also the SETUP. I tested different projection angle and with "Total triangulation angle" 19.18° i had lines in the scan. Recalibrate with "Total triangulation angle" 23.89° and the lines disappear. Also the alignm...

i am really exited about the calibration routine of flexscan3d. The DOF is also beeing considered... https://www.youtube.com/watch?v=ovnn6sSlSHk And here's another very similar: https://www.scaninabox.com/ It too uses a single flat panel and multiple "scans" for calibration. I actually ho...
