摘　　要：为了保证三线阵测绘相机装调后相机之间的空间位置关系,保证三线阵测绘相机应用时的测绘精度和图像质量,对三线阵测绘相机CCD像面的装调方法进行研究。首先,根据测绘精度和图像质量的要求,明确了三线阵测绘相机的装调指标。其次,确定了装调方案,对装调要点进行了叙述,为三线阵测绘相机的装调提供了一种装调方法。实际装调检测结果表明,应用该方法可以将相机之间空间位置关系安装到α≤3"、β≤5"、γ≤5"。该方法可以满足三线阵测绘相机之间的空间位置关系装调,具有实际应用价值。In order to ensure the space position relations among cameras, mapping precision and picture quality when three-line array mapping camera is used, three-line array mapping camera alignment was studied. CCD image plane alignment method of three-line array mapping camera was investigated. First, according to the require- ment of mapping precision and picture quality, three-line array camera alignment indicators are cleared. Second, the alignment scheme is identified, the alignment key points are described and an alignment method for three-line array mapping camera is given. Actual test shows that the space position relations among cameras can be installed as a 〈 3 ″, β 〈 5″, y 〈 5″ using this method. This method can satisfy the alignment requirements of space position relations of three-line array mapping camera and has practical application value.
