Trajectory visualization #3

Hello, may I ask how the pedestrian trajectory visualization in the paper is realized? image image

InhwanBae commented 1 year ago

Hi @caaaadac!

Basically, I use Matplotlib Plot to visualize the path. For better visualization, I additionally use OpenCV VideoCapture to obtain still images and convert the generated trajectories from a meter coordinate system to an image coordinate system via a homography matrix. This conversion allows the trajectory points to be drawn in the correct head positions of pedestrians on the image.

I'm closing this issue for now. Please feel free to open another issue for other questions.

Hi @InhwanBae, thanks for the nice work! Would you mind sharing your visualization code? I am interested in reproducing the visualization.
