We have a new GL3Dview.exe which has
many more features than the old one. If you view the old tutorial, you can find
most of those features in the drop down menus in the new version.

3-DIMENSIONAL GALLERY
Chris K has downloaded and
gotten the UofKScannerLT system running with his Logitech camera. The quality
of the scans are extremely good for a Logitech camera.
Chris K has sent us more
examples which I am putting on a separate CHRIS K
WEBPAGE. If you click on images, you can download the imbedded mat5 form or
*F.bmp and view in our new GL3Dview.exe program.
MAPPING LOW RESOLUTION DEPTH SCANS TO HIGH RESOLUTION
TEXTURE IMAGES (LOW TO HIGH RES AUTO SKINNING)
The idea is here is to get a
mat5 data set from a scanner and then immediately take a high resolution
texture image using a digital camera. The program leastsquaretriangle.exe can
be used to interpolate the low resolution depth scan to the high resolution
mat5 with the high resolution texture image as the C.bmp file. The key to doing
this is to lock down the scanner camera and projector as well as the high
resolution digital camera to the same reference frame or structure. The digital
camera can be manually trigger and the jpg image can be downloaded offline
manually. Once the components are locked down, a calibration grid is scanned by
the scanner and captured by the digital camera. The program calibrate.exe is
designed to first process the calibration grid for depth and then put in
texture mode to calibrate the digital camera. Once this is done, the system can
be used to capture objects and as long as they remain locked to the same
structure and no zoom or magnification values are changed, the sytem does not
have to be recalibrated. The program for mapping is leastsquaretriangle.exe. http://www.joeledelstein.com, was able
to perform this with the Logitech webcam software and his own digital camera.
His results can be downloaded from the link below.
