  • As the geometric precision of a three-line array CCD tridimensional mapping camera is one of the important factors to affect the mapping precision, the assembly method for the mapping camera is studied to build and ensure the spatial geometry relation of the mapping cameras. Firstly, the structure of mapping camera system and the definition of the coordinate are introduced. Then, the assembly requirements of the basal mirrors and the mapping camera are brought out. Finally, the assembly process of the mapping camera is determined, and its assembly steps are significantly introduced. After the camera alignment, the results show that the Optical Transfer Function(OTF) of the mapping camera is more than 0.2, and its distortion is less than 0.03%. Moreover, the space position relation among cameras can meet the installing requirements. The method can satisfy the alignment requirements of space geometry precision of the three-line array CCD tridimensional mapping camera.
