Question about 2D bounding box #40

Open gray311 opened 2 months ago

gray311 commented 2 months ago

I want to transform the 3d_bbs to 2D bounding boxes of the each frame, but I can't get extrinsic matrix of the sensor. Can you offer some suggestions for me to get 2D bbox? Thanks!

Hi! Sorry for the late reply! You can find the bbox of the traffic lights, walkers, and vehicles in the actors_data. These coordinates are based on a system that originates at the ego-vehicle and do not require additional transformations."
