飞行器实测图像几何校正要求计算时间短且所用程序内存小。论述了采用增量递推的算法优化图像几何校正算法;同时结合TMS320C6201DSP编译器特点,采用泰勒级数展开收敛函数满足了误差要求;根据正交矩阵特点简化参数求解,使运算满足了实时系统的要求。
Geometric correction of the measured image of the aircraft requires a short calculation time and a small program memory. In the meantime, the algorithm of TMS320C6201DSP compiler is used to optimize the image geometric correction algorithm. The Taylor series expansion function is used to satisfy the error requirement. According to the characteristics of orthogonal matrix, the parameters are solved to make the algorithm satisfy the real-time system Claim.
