Closed-loop control aerial survey unmanned aerial vehicle

Abstract

The invention discloses a closed-loop control aerial survey unmanned aerial vehicle which is provided with a flight control system and a camera, the flight control system records exterior orientation data, and the camera executes image acquisition. The unmanned aerial vehicle is further provided with an additional module, the additional module is connected between the flight control system and the camera, the camera is controlled to execute image acquisition while the flight control system records exterior orientation data, it is guaranteed that orientation data correspond to images, and measuring point data incompleteness is avoided.

Description

technical field [0001] The invention relates to a closed-loop controlled aerial survey unmanned aerial vehicle, which belongs to the technical field of aerial survey equipment. Background technique [0002] UAV aerial surveys must simultaneously acquire images and corresponding external orientation data, including three-axis attitude, position coordinates, etc., to provide basic data for later image correction, fusion, and splicing. [0003] In the prior art, the aerial survey image is obtained by taking photos with the camera carried by the UAV, and the external orientation data is provided by the airborne flight controller. While the flight controller outputs the camera control signal, it extracts the external orientation data for storage and recording. However, if the camera does not read the signal or other reasons cause the camera not to be executed, the data will be incomplete, resulting in post-data processing errors. [0004] UAV flight safety depends on the stabil...
