对航空CCD相机机械拼接焦面搭接区域内由于2个CCD像移量不同导致的像点错位问题进行了分析。首先，根据航空中心投影成像的几何关系，给出了正直摄影时地面起伏导致的搭接区相对像移量，然后，由共线方程出发，建立了搭接区相对像移量的数学模型，分析了载机姿态、地面起伏、CCD拼接距离等因素对搭接区相对像移量的影响。最后，根据建立的数学模型及工程应用实例选取了补偿载机姿态变化的稳定平台，并给出了搭接区相对像移量的数值分析结果。本文建立的搭接区数学模型对采用机械拼接方案的航空相机具有一定的工程和应用意义。

Influences on relative pixel displacement in overlapping area of mechanical assembly CCD focal planes in remote sensing cameras are studied. Various factors, such as stability of the platform, wavy terrain, distance between two spliced CCDs, are taken into account. The relative pixel displacement of normal photography due to the wavy terrain is studied by using the geometric relationship of central projection. Starting from the collinear equation, the exact mathematical model of the relative pixel displacement is derived by using analytic method. According to the model founded and an example with engineering application, the corresponding stabilized platform is determined, and the numerical results are given. The study has engineering sense and practical value in actual project.
