The Lidar sensor setup could be referred as the illustration figure below:
The ego front is x-axis, the left side is y-axis and the upwards is z-axis. Each position of
environment agent is encoded with a 7-dimension vector, i.e., (x, y, z, length, width, height, orientation)
.
orientation is in range (-pi, pi]
, which is illustrated in above figure.
CenterPoint use point pillar to extract points cloud's features and then scatter the features to pseudo image, the figure below illustrate the global indices detail between real physical world and pseudo image space. The global indexing method used in scatter module should be the same with the ground truth (heatmap) generation logic.
