No Points Added to Point Cloud

Created by Ryan Riley, Modified on Thu, 25 Jun at 4:00 PM by Ryan Riley

Several factors could cause no points to be added to the point cloud.

  1. Do PCAP file sizes look okay?
    1. Should be tens or dozens of MBs (for all but first and last file, which may be shorter)
  2. Are PCAPs from the correct flight?
    1. With Velodyne LiDAR you can investigate the GPRMC message in Wireshark, use an online GPRMC decoder, and see the time and position of the packets and compare to the trajectory.
    2. GRYFN Processing Tool logs should also give an indication of the times not aligning to the trajectory.
      1. Could not retrieve an EOP for timestamp:
  3. Are the minimum and maximum laser ranges inclusive of the required point distance from the flight?
