Dear Sir or Ma'am,

This question is related to these others:

We finally got ahold of a Flea camera and now no longer have problems running the software. We are able to follow all the instructions in TIDUC48A up until step 2.5.5. We were able to create the calibration board and calibrate the camera. We tried to calibrate the projector but our projector does not project the checkerboard, instead only projecting a white screen. It is able to project a multicolored band of light in other contexts. How do we get the projector to show a checkerboard during projector calibration? Attached is my config and calibration information under the "TIDA-00254_3D_Scanner_LCr4500-2.0\\LCr4500_3D_Scanner_Application_v2" directory.

Hi Miguel,

Did you try attaching the images you want to display with the DLPC350 firmware? after attaching you can try reuploading the firmware and then displaying the patterns from flash. Let me know if this works out.

Thanks & Regards,
Hirak.

I apologize, I moved my equipment to a new lab and just sat down to try it again. Now I have an issue with the camera calibration. I can trigger the camera to take the picture, but I cannot get the projector to display the white light as advertised in this message:

<<<<<<<<<<<<<<<<<<<<<< Calibrating the Camera >>>>>>>>>>>>>>>>>>>>>>
Loading camera calibration settings...
Setting up camera calibration
Projecting white pattern to illuminate calibration board
Calibrating camera...
Calibration boards required = 20
Calibration boards captured = 0

When I initially turn on the DLP4500 I get a colored line pattern, so I know the projector itself works. However, whatever triggers it to turn on at that time does not function.

Thanks & Regards,
