Xianhong Wang · Chuangan jishu xuebao · 2010
An electronic elimiating rotation method based on mathematic platform is put forward,which can be used on image rotation by carrier perturbation when the video theodolite tracks target on the active pedestal. The hardware system with strapdown inertial navigation equipment,DSP and FPGA,can elimate rotation and fill the image by reverse rotation and bilinear interpolation.This system developed has successfully applied in minitype shipboard theodolite,can complete the restoration of 720×576×24 color video image,and achieve frame frequency with 25 frame/s for one fine quality image and less then one pure pixel level of maximum pixel error.
