Example of UDP Data Analysis
Take PandarQT’s Channel 5 in Block 3 of the UDP Data as an example:
1) Vertical angle of Channel 5 is 43.877°, according to the calibration file included with each LiDAR.
1. Horizontal angle is the current reference angle of the rotor (Azimuth of Block 3) plus the horizontal angle offset (7.388°, according to the calibration file
included with each LiDAR). Define clockwise in the top view as the horizontal angles’ positive direction
2. The 2-byte distance data in the UDP Data Packet, multiplied by 4 mm, is the actual distance in real world millimeters.
After determining the horizontal angle, vertical angle, and distance of a data point, this point can be drawn in a polar or rectangular coordinate system. The
real-time point cloud data is drawn by analyzing every point in the UDP data.
