The UAV Verification Experiment of On-orbit Dynamic Scene Matching
In order to improve the imaging quality of remote sensing camera,this paper proposes a working pattern of metering,calculating and imaging.In order to verify its effectiveness on-orbit,this paper designs a dynamic scene matching verification system based on unmanned aerial vehicle and the flight experiments were carried out.The verification system includes metering camera,imaging cameras,acquisition processing,ground monitoring control and other parts.There is a certain preset angle between the metering camera and the imaging camera,before the imaging camera is push-broom imaging a certain area,the image of this area can be obtained by metering camera in advance,and the highest luminance information of this area can be measured.Then,Exposal parameters of the imaging camera can be calculated by setting the highest luminance information measured before as the saturation luminance of the imaging camera.Finally,when the imaging camera focuses on this area after orbiting to a certain extent,the imaging camera could realize dynamic scene matching by adopting exposure parameters calculated previously.The flight experiments in Dalian obtained the high-resolution image with a resolution of 0.01m.Experiment results show that,the realization of matching method is simple and can achieve in 1s.The proposed method can obtained well exposure images and the image details are rich.This experiment provides support for the practical application on-orbit.
