Problems solved by technology

[0002] Geographic information has become an important resource. In order to obtain geographic information accurately, various methods such as satellites, airplanes, unmanned aerial vehicles, and field surveys have been adopted to obtain geographic information. Satellites fly at the highest altitude and have the widest viewing angle, but the accuracy is relatively low. Low, the field survey range is the smallest, but the accuracy is the highest, while the aircraft and drones are in the middle position, which can achieve both. However, in the actual use process, some places are forbidden air areas, and aircrafts are prohibited from flying. , so there is a need for a device that can be used in restricted areas, has a better viewing angle than field surveys, and has relatively good geographic information acquisition effects

Abstract

The invention relates to the technical field of image collection equipment, in particular to a feature extraction device and method for a geographic information image. The device comprises a moving carrier, a lifting mechanism and an obtaining mechanism, the moving carrier can conveniently and quickly move at any position, the lifting mechanism can change any height and angle, the obtaining mechanism can change the height and angle according to needs, and therefore needed image information is obtained. According to the invention, images can be flexibly and conveniently collected, the cost is low, the entrance threshold is low, and a good collection visual angle is provided.

Description

technical field [0001] The present invention relates to the technical field of image acquisition equipment, and more particularly, to a feature extraction device and method for geographic information images. Background technique [0002] Geographic information has become an important resource. In order to accurately obtain geographic information, various methods such as satellites, aircraft, unmanned aerial vehicles, and field surveys have been adopted. Satellites have the highest flying altitude and the widest viewing angle, but the accuracy is relatively low Low, the scope of on-site survey is the smallest, but the accuracy is the highest, while the aircraft and UAV are in the middle position, which can achieve both. Therefore, there is a need for a device that can be used in forbidden areas, has a better viewing angle than field surveys, and has relatively good geographic information acquisition effects. SUMMARY OF THE INVENTION [0003] The device and method for extra...
