Embodiment Construction

[0041] The invention provides a system and method for managing ecological civilization of an air-ground integrated city based on Beidou positioning. In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] In order to facilitate understanding, first introduce the Beidou satellite navigation system.

[0043] BeiDou (COMPASS) Navigation Satellite System﹞ has the functions of positioning, timing, message and GPS wide-area difference in China and its surrounding areas, and is used in surveying and mapping, telecommunications, water conservancy, transportation, fishery, exploration , forest fire prevention and national security and many other fields g...

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

technical field [0001] The invention relates to the technical field of urban ecological civilization management, in particular to an urban ecological civilization management system and method based on Beidou positioning. Background technique [0002] Ecological civilization is a new stage in the development of human civilization, that is, the civilization form of the socialization of world ethics after industrial civilization; ecological civilization is the sum of material and spiritual achievements obtained by human beings following the objective law of harmonious development of man, nature and society ; Ecological civilization is a cultural and ethical form based on the basic purpose of harmonious coexistence between man and nature, man and man, and man and society, virtuous circle, all-round development, and sustainable prosperity. From the perspective of harmony between man and nature, the definition of the achievements of the 18th National Congress of the Communist Pa...
