Altos 4D Imaging Radar -- Road testing point cloud

Real time, Onboard computed point cloud from Altos 4D imaging Radar.
Left Video (Colored by height)
1. Red - closer to ground; Purple - high in the air
2. The larger points are from Radar, the smaller (and denser) points on the background are from Lidar (for reference).
Right Video (Color by ground speed)
Yellow : Points from a 128 line Lidar
Green: Stationary Points
Red: Approaching Points
Purple: Departing Points
Note:
1. There is x3 acceleration for the video, and equivalently 3-frame accumulation for the Radar points (due to decay time setting in the replay).
2. The lighter grid on the ground is 20m x 20m, the brighter grid is 100m x 100m
