Automatic photographing path planning and flying method of unmanned aerial vehicle for territorial survey proof

Abstract

The invention relates to the technical field of territorial survey proof, and discloses an automatic photographing path planning and flying method of an unmanned aerial vehicle for territorial survey proof, which comprises the following steps: according to pattern spot distribution of an operation area, adopting a manual interaction mode, firstly selecting proof pattern spots, and then appointing a pattern spot proof sequence; automatically extracting pattern spot proof shooting points by a program; the program referring to DEM data and flight height setting, automatically calculating the flight height of each pattern spot proof photographing point, and automatically generating an unmanned aerial vehicle photographing path; performing one-key flight on an investigation proof work site; the unmanned aerial vehicle carrying out automatic flight evidence-proof photographing on the evidence-proof photographing point along the flight route, and transmitting the unmanned aerial vehicle attitude and photographing information back in an encryption mode; and after field work proof is completed, performing automatic homeward voyage. According to the invention, the ability of human intervention can be well exerted, regular work such as setting of positive shooting and oblique shooting points can be automatically completed, and the working efficiency of shooting path planning and field evidence can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of land investigation and evidence production, and in particular relates to a method for automatically planning and flying a UAV photographing path for land investigation and evidence production. Background technique [0002] In order to improve the system of land survey, monitoring and statistics, strengthen the information service of land resources, and meet the needs of economic and social development and land resources management, it is necessary to analyze the inconsistencies between the land types identified by local field surveys and the land types interpreted by the industry, as well as the unidentified images. It can be reflected that all the newly added features in the local supplementary survey survey need all on-the-spot evidence. Obtaining real and accurate field survey data such as map-pattern land types and map-pattern boundaries is an important source and key link for data acquisition in natio...
