Why 2D bounding box mismatch the image? #66

Closed mrsempress closed 10 months ago

mrsempress commented 10 months ago

I use the following computation to get the position of the 2D bounding box, but it doesn't match the object in the image. img from lower_wide[time_id] intrinsics = lower_wide_intrinsics[time_id] extrinsics from lowres_wide.traj corners from the data_prepare_offline.py

I wonder whether the intrinsic matrix divides 1920/256(7.5) as a low resolution. And do I miss something operation?
