摘　　要：我国近期发射的月球探测器携带了全景相机的科学载荷,负责获取巡视器着陆区的月球表面影像。全景相机共有两台,采用双目立体成像,实际工作时保持相对位置和姿态关系不变。参考地球测绘、计算机视觉等领域的多个相似案例,使用一种改进的平差模型,经过实验验证,证明该模型能够消除不同立体像对间相对位置和姿态的偏差,使平差结果更加可靠,为我国探月任务中月表全景相机影像数据的摄影测量处理提供帮助和支持。The lunar probe launched recently in China carries the scientific load of the panoramic camera,which is responsible for the important task of acquiring lunar surface image of the landing area of the inspector.The two panoramic cameras in the lunar probe use the method of binocular stereo imaging and the relative position and pose between cameras remain unchanged during the imaging process.After consulting several similar cases in the fields of earth surveying and mapping and computer vision,an improved adjustment model is used.Test results show that the new model can eliminate the deviation of relative position and attitude between different stereo pairs and makes the adjustment results more reliable.In conclusion,the new adjustment algorithm can provide help and support for photogrammetric processing of lunar panoramic camera image data in lunar exploration missions in China.
