Abstract :
A novel approach for scene matching real-time image geometric rectification is proposed. Based on the analysis of the reason caused geometric distortion in the process of real-time image capturing, two coordinates system are given, the real-time image distortion classification are analyzed, and the distortion mathematic models are established. Then, the geometric rectification of the real-time image is realized according to the aircraft camera¿s height and attitude angle information, including method for calculating the offset and determining the size of the new real-time image. Simulation experimental results proved the validity and the efficiency of the approach.
