Air-ground integrated city ecological civilization managing system and method based on Beidou positioning

Abstract

The invention discloses an air-ground integrated city ecological civilization managing system and method based on Beidou positioning. Satellites, unmanned planes, vehicles and the like carried with Beidou satellite navigation and positioning terminals collect satellite and low-altitude aerial photography images as well as vehicle laser scanning, vehicle video shooting and ground fixed-point shooting data, 2D texture images and 3D point cloud data of a large-scale scene are rapidly and completely obtained from the data in various manners, and segmentation, classification, identification and high-dimensional reconstruction of the large-scene are realized based on the multi-source combined data. Compared with the prior art, the system and method have the advantages that the precision of a scene model can reach the centimeter level which is greatly higher than the meter level of a traditional method, and practical measurement, calculation and verification show that the data collecting and processing time is only about 1 / 4 that of the traditional method.

Description
