Embodiment Construction
[0025] UAV aerial photography remote sensing forest measurement technology is different from the existing technology and has been greatly improved, specifically:
[0026] UAV low-altitude aircraft is used as the remote sensing platform, which integrates ordinary digital camera, differential GPS and gyro platform, and uses digital photography technology to obtain low-altitude UAV remote sensing images with high ground resolution and large scale; through computer digital image processing system , for forest farms, according to the conformation rules of ground objects and image characteristics, the quantity and quality of forest stand investigation factors are identified and measured on images, and the tree measurement factors interpreted on images are: canopy density, tree height, tree crown diameter and tree number The equal factor is the function of the measured volume on the ground, and the aerial standing tree volume table and the aerial forest stand volume table are compiled...
