LCr 4500 does not project any illumination for some menus of 3D scanning

Hello Tom,

Can you send the Debug log? If you are compiling the code then can you rebuild the exe with following changes in the main.cpp, this will show what all happening in the projector and camera communication.

Regards,

Sanjeev

int main()

{    

   // System Variables

   dlp::PG_FlyCap2_C   camera;

   dlp::LCr4500        projector;

   // Strucrtured Light modules

   dlp::GrayCode structured_light_vertical;

   dlp::GrayCode structured_light_horizontal;

   unsigned int total_pattern_count = 0;

   camera.SetDebugEnable(false);

   projector.SetDebugEnable(false);

   camera.SetDebugEnable(true);

   projector.SetDebugEnable(true);

....

}

Sanjeev,

Thanks for your response. Well, looking at process of recompiling the source in the document, it could take a whole day to set the development environment and recompile OpenCv and then source with MinGW in order to comment out a few lines of code. I can't help thinking why the program does not have an option to do that. Anyway, I will try what you recommended. :-)

Sanjeev

I've finally done what you suggested. Below is whole content of the recompiled program. As far as I can see, there is no particularly useful information. Please let me know if you have any other idea. Thanks.
