Design and Research of Three-Axis Stabilized Platform for Image Motion Compensation of Aerial Camera
During the working process of the aerial camera,due to the interference of the camera shake,the image motion will oc-cur during the shooting process,and the image motion is the main reason for the image quality.Equipping an aerial camera with a stable platform system is an effective solution to the problem of image motion.The principle of the stable platform system is to sta-bilize the sensor's line of sight toward a target by isolating the aerial camera imaging sensor from interference.In order to stabi-lize the line of sight and realize push-broom shooting,a three-axis stabilized platform is designed in this paper,and the attitude compensation method and structure design of the three-axis stabilized platform are studied.By analyzing the effect of image mo-tion on image quality,the rotation accuracy of the shaft system is determined,and the platform compensation equation based on the angular velocity of the cross-coupling of the roll axis,pitch axis and the heading axis frame is derived.Then,according to the shafting accuracy and motion compensation equation,the three-axis stable platform structure was designed and analyzed,and the performance of the visual axis stability was verified through experiments.The experimental results show that the platform has good stable performance under carrier interference.
