Point Cloud Data Analysis
Take Channel 5 in Block 2 as an example:
■ Analyze the vertical angle of a data point
The designed vertical angle of Channel 5 is -46.695°, according to Appendix I (Channel Distribution)
Notes
·
The accurate vertical angle is recorded in this LiDAR's unit's angle correction file, see Section 1.3 (Channel Distribution).
·
0° is the horizontal direction; define upward as positive (see Figure 1.5).
·
Channel # counts from 1, bottom to top.
■ Analyze the horizontal angle of a data point
Y-axis is the 0° position; define clockwise in the top view as positive (see Figure 1.4).
Horizontal angle = ① + ②
① Angular position of current block (see Appendix II for definition)
② Firing time angular offset of the current firing channel
