Issue with getting results

[shameal205]

Hello,
Could I get some help with an SDF issue? I'm new to the field but I'm trying to use my own data set, I can get SDF maps similar to the demo, but I'm unable to get passed that. All my "voxel.sdf" values are above 0 and get skipped over in the "ExtractVoxel" function in "extract_voxel.cc". What in my dataset could I do to avoid

Thank you in advance!

The simplest way is passing the silhouette image in black and white as in examples.cc

Just in case, the image you posted below in red and blue is NOT SDF (32-bit float one channel in this implementation) itself; It's a visualization of SDF in 8-bit uchar (0-255) 3 channels.
It shouldn't be an input to this code.

Reasons for failures with valid image inputs would be either your camera parameters or voxel initialization range (set in bb_max and bb_min) is wrong.
Note that this code uses the OpenCV camera coordinate. If you want to pass the ones from CG software such as Blender to this code, you must convert them correctly.
