探测器拼接几何参数获取是验证以及评价拼接成功的关键因素之一，但几何参数获取技术的系统性方法一直没有形成。对于探测器微缝拼接过程中的两个探测器之间的旋转，与狭缝垂直方向的平移，狭缝宽度等重要几何量，基于成像的测试方法可以给出非常准确的结果。另外，利用影像测量仪可以对探测器拼接狭缝的平均宽度进行实际测量，两者结果类似。证明基于成像的测试方法能够一次性完成多种几何特征量的测试，并且能够保证较高精度，这正好满足航天应用快捷、高精度的需要，可以为探测器微缝拼接提供强有力的技术支撑。

The geometric parameters acquisition of splice detector is the most important thing to validate and evaluate the success of splice, but there is no systematic approach to solve it. For the rotation between the two detectors, the translation of the vertical slit, the slit width and other geometric parameters, the method based on imaging can give very accurate results. On the other hand, the smart-scope can give us the actual mean width of detector splicing, and the results are similar to the above. It proves that the method based on imaging can complete various geometric parameters tests with a very high precision. It just meets the needs of easy and high precision of the aerospace application, and it can provide powerful technical support for the detector slit splicing.
