Aerial survey high-level automatic partition method

Abstract

The present invention relates to an aerial survey high-level automatic zoning method, which is characterized in that it comprises the following steps: S101, obtaining the aerial photograph map of the area that needs aerial survey, and determining the specific area that needs aerial survey; Grid sampling to obtain high-level data, and generate a height grayscale image; S103, stratify the specific area of ​​the aerial survey; S104, perform binary processing on each layer of the specific area of ​​the aerial survey to obtain a binary image; S105, Execute the connected domain detection algorithm on the value image to extract the connected domains separated from each other in each layer; S106, for each connected domain, perform contour detection to obtain the contour of each connected domain; S107, perform vectorization processing on the contour of the connected domain ; S108 , importing the connected domain information of each layer into the ground station, and planning corresponding aerial survey tasks. The invention can realize the stratification of the aerial survey area, which is convenient for the aerial survey to plan aerial survey tasks for different stratifications respectively.

Description
