Aerial survey high-level automatic zoning method

Abstract

The invention relates to an aerial survey high-level automatic zoning method, which is characterized in that the method comprises the following steps of S101 acquiring an aerial photograph of a regionto be aerial surveyed and determining a specific region to be aerial surveyed; S102 sampling the specific area of the aerial survey with an equal distance grid, obtaining high-level data, and generating a high-gray image; S103 layering the specific area of the aerial survey; S104 binarizing each layer of the specific area of the aerial survey to obtain a binary image; S105 executing a connected region detection algorithm on the binary image, and extracting connected regions separated from each other in each layer; 106 performing the contour detection for each connected region to obtain that contour of each connected region; S107 vectorizing the contour of the connected region; S108 importing the information of the connected area of each layer into the ground station, and planning the corresponding aerial survey task. The method of the invention can realize the stratification of the aerial survey area, and is convenient for the aerial survey to plan the aerial survey tasks for different stratification.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an aerial survey high-level automatic partition method. Background technique [0002] UAV aerial survey is a powerful supplement to traditional aerial photogrammetry.
