Hello,
I'm analyzing a point cloud dataset captured by a lidar sensor and have a question regarding its Vertical Field Of View (VFOV) channel configuration. The dataset documentation suggests the VFOV configuration shown in the attached image (lidar_beam.png), but my analysis (Screenshot.png) of the data implies a different setup. Specifically, the data near the origin (where the lidar is located) was captured by channel/lidar_beam 63, and as the distance from the origin increases, the channel number decreases sequentially down to channel 0. This pattern suggests that the channels are arranged vertically from bottom to top in the order of 63 to 0 rather than the even/odd pattern suggest by the lidar_beam.png. Can you provide insights or confirm if my understanding of the channel configuration being 63 (lowest) to 0 (highest) along the z-axis is correct?
You may want to add more information about what type of LiDAR system you have and other specifics about your setup like is this a ground ground based LiDAR or aerial LiDAR or other experimental? You may harvest better answers from others experts reading your question if more details are included. One thought is can you physically measure control (reference) points to your also physically measured origin to validate the LiDAR points from VFOV data?
