4.1.4 Point Cloud Data Parsing
If you need to parse Lidar data, please follow the steps below:
Step 1
. Parse the data package to obtain the relative horizontal angle, ranging
information, intensity data and microsecond timestamp information of each laser;
Step 2
. Read the device package to obtain information such as the horizontal correction
angle value, UTC (GPS or NTP time service) and the current configuration of the device;
Step 3
. Obtain the vertical angle of each line according to the laser beam distribution;
Step 4
. According to the distance measurement value, vertical angle and the calculated
horizontal angle of the point cloud data, the XYZ coordinate values are obtained;
Step 5
. If necessary, calculate the precise time of the point cloud data through UTC,
microsecond timestamp, light-emitting time of each laser, as well as single and dual
echo modes;
Step 6
. Reconfigure information such as Ethernet, PPS synchronization horizontal
angle, motor speed and other information as needed, and pack the configuration
package protocol.
