摘　　要：随着对实时立体测绘图像的需求,相机探测器由胶片向CCD发展。为了保证三线阵测绘相机的测绘精度,文章对三线阵测绘相机的视轴夹角及线阵平行性的装调检测进行了研究,针对测试指标提出了新的装调测试方案,并对方案中的关键技术进行了阐述。实际装调检测结果表明,该方案能够满足多相机间夹角测试精度优于5″,CCD线阵不平行度测试精度优于15″的要求。可以满足三线阵测绘相机空间位置的装调测试,具有实际应用价值。With the demand of three-dimensional mapping images ,the camera detector has been developed from the film to CCD. In order to ensure the mapping accuracy of the three-line array camera,a new alignment method is proposed for camera axis angle and parallelism of CCD linear array. The method proposes a new test scheme and describes the key technology. The results show that this method can meet the test accuracy of the multi-camera angle and the parallelism of the CCD linear array. This method can satisfy the requirements for alignment and test of the space location of the three-line array camera;it has practical value.
