zwyking commented 4 years ago

there is an attribute pids of the Image , i want to understand what is meaning of the data of pids

etrulls commented 4 years ago

Where? I opened an h5 depth map file and I don't see anything like this. Please be specific when asking for help.

zwyking commented 4 years ago

oh ，sorry! I mistaken the attribute. p = images[idx].xys It's the images[idx].xys.

etrulls commented 4 years ago

I assume that comes from reading the binary files provided by colmap. The "xys" are keypoint locations, you can see how to use them here (which I guess is where you got that snippet from?). Should be pretty self-explanatory, but please refer to the Colmap documentation if still in doubt.
