Visualize/compute light prediction #9

Closed mcleanalec closed 3 years ago

mcleanalec commented 3 years ago

It's not clear within the code how to compute/visualize the light direction. How do you do that?

From the output I can see pred_boxes and pred_light. The units of pred_light are not clear - I can see from the paper/code you use the atan2 function but I am not sure how to use those units. Can you elaborate, please?

As mention in the paper, we roughly compute the 2D light direction based on the center of object and shadow. This is more accurate than the Pred_light, which only helps network to find the associations.
