Alpine landforms are mainly characterized by large height differences. When the airborne lidar is scanning, the point cloud density of the lowest point and the highest point is very different. In the effective altitude range, to ensure the lowest point cloud density, the laser radar maximum laser emission frequency To be higher, the current laser radar with a laser emission frequency of 800 KHz -2000KHz has better Aerial photography effects.
Feiyan Remote sensing’s own RIEGL VQ-1560i airborne lidar has a maximum launch frequency of 2 million Hz, an effective ground measurement speed of 1,330,000 points per second, and can operate at an altitude of up to 4,700 meters. It is especially suitable for Aerial Surveying and mapping in complex environments.
