Description

technical field [0001] The invention relates to the field of intelligent embedded video processing, in particular to a dynamic stepless derotation system and method based on high-level synthesis of large-scale integrated circuits. Background technique [0002] During the video recording and aiming process of the airborne pod, the outer frame structure of the TV will inevitably undergo rolling motion, which will cause relative movement of the optical system relative to the carrier aircraft, resulting in image rotation; During the process, the fuselage often rolls at a large angle (even up to 360°), which causes the TV screen to rotate at a large angle, which seriously affects the perception of the operator. Therefore, in many optical sighting devices or photoelectric pod systems, in order to eliminate the image rotation problem caused by the attitude change of the aircraft, it is necessary to perform anti-rotation processing on the original video image acquired by the TV syst...

Problems solved by technology

At present, there are three common derotation methods in practical engineering applications, namely electronic derotation, optical derotation and physical derotation. Optical derotation is currently the most used method, which corrects the image by rotating the derotation prism in the imaging optical path , although this method has low delay and fast response speed, but its processing technology is complex, the accuracy of race-rotation angle is low, and the system volume and power consumption are large
