100-2000kHz PRR 5mm@50m accuracy 1500m range PM-1500 airborne LiDAR system for topographic mapping of complex terrain
At present, the traditional topographic mapping is mostly carried out by aerial photogrammetry, which is more effective for the mapping of small-scale topographic map. Facing the operation demand of large-scale topographic mapping, especially the mountain topographic mapping with high drop and dense forest, the applicability and operation efficiency of photogrammetry need to be further improved. With the development of 3D laser scanning technology and the emergence of airborne LiDAR technology, it brings new solutions for topographic mapping of complex terrain scenes.
PM-1500 airborne LiDAR has the characteristics of high point frequency, high line frequency and long range, which can effectively solve the difficulties of topographic mapping of high drop terrain. In addition, PM-1500 also has four times echo. Based on the echo information, the ground vegetation can be filtered out to obtain the real terrain information. The 3D point cloud based on the terrain and surface can realize 4D products automatically or semi automatically to meet the needs of topographic mapping of complex terrain scenes.
Features
1. Longer range up to 1500m@60% with 5mm@50m accuracy
2. FoV 75°, wider flight strip, higher operation efficiency
3. 4 times echo, penetrate through the vegetation gap to obtain real terrain information
4. Real time point cloud display, real-time feedback data
5. One-stop data processing with independently developed software
