Document Type and Number:
WIPO Patent Application WO/2020/192199
Kind Code:
A1
Abstract:
Provided are an aerial survey method and apparatus with a redundant aerial photograph elimination function. The method comprises the following sequential steps: S1. according to attitude information of an aircraft or an aerial camera at a photographing coordinate point, parameter information of the aerial camera and regional geographic information of a target region, acquiring ground projection data of aerial photographs on the photographing coordinate point; and S2. comparing the ground projection data acquired in S1 with known data of the target region, and if there is an intersection between the two pieces of data, acquiring aerial data of the photographing coordinate point, and if there is no intersection therebetween, eliminating the aerial data of the photographing coordinate point, or not performing aerial photography on the photographing coordinate point. By using the method and apparatus, the data processing volume in an aerial survey operation process can be effectively reduced, and data processing efficiency can be improved.
