a question about the contrib/rgbd /src/normal_lut.i
.
// Auto-generated by scripts/create_depth_normal_lut.py 20
static const int GRANULARITY = 20;
static const unsigned char NORMAL_LUT[20][20][20]={..........................................................}
the first line, create_depth_normal_lut.py ,I think this file is made by it , but I can't find the .py file , where I can find it or if I want to make my own data , what to do with it?
it is indeed not part of the opencv src. you might have to contact the original author (Rostislav Vasilikhin, aka savour)
(email is in the git logs)
