摘要
介绍了机载光电探测航姿信息融合的必要性,阐述了航姿信息融合算法的基本原理,具体描述了融合算法的实现过程,算法主体思路是通过3次坐标系的转换,将目标在传感器图像上的位置坐标变换到一个稳定的不受飞机姿态影响的基准坐标系里,并给出了坐标系变换的确切数学表达式.最后给出了一个采用该算法的系统的实际演示效果和详细数据,证明了算法的有效性.
The importance of data fusion algorithm of attitude heading for Airborne Electro-Optic Detection is introduced. The basic principium of data fusion algorithm is illuminated, and the processing of the data fusion algorithm is described . According to this algorithm, reference frame should be mainly conversed three times to change the target position coordinate on-image of the sensor into a fiducial reference frame being independent of the aircraft, an exact mathematical expression of reference frame conversion is given. Lastly, the practical demo and data of actual system implementing the data fusion algorithm are presented to validate the data fusion algorithm.
