Title
(EN) Aerial survey method and device with redundant aerial photo elimination function
(ZH) 一种可剔除多余航片的航测方法和装置
Abstract
(EN)
The invention discloses an aerial survey method and device with a redundant aerial photo elimination function. The method comprises the sequential steps that S1, according to attitude information of an aircraft or an aerial camera at a shooting coordinate point, parameter information of the aerial camera and regional geographic information of a target region, ground projection data of aerial photos on the shooting coordinate point is obtained; and S2,the ground projection data obtained in S1 is compared with target region known data, if the two kinds of data have an intersection, aerial data of the shooting coordinate point is obtained, or otherwise the aerial data of the shooting coordinate point is eliminated, or aerial shooting is not performed on the shooting coordinate point. The device serves as hardware support of the method. By the adoption of the aerial survey method and device, the data processing volume in the aerial survey operation process can be effectively reduced, and data processing efficiency can be improved.
