从嫦娥三号全景相机的特点(双目相机)出发，提出了一种针对图像像对质量进行评价的方法，即结构相似度(SSIM)的评价方法。在分析了嫦娥三号全景相机成像原理以及以往采用的评价因子的基础上，运用此方法对全景相机所获得的图像像对进行了质量评价。该评价因子能够很好地适用于嫦娥三号全景相机所获得图像像对的质量评价，并且优于常用的一般评价因子。实验表明此评价方法在像对质量评价上具有一定的优势。为后续全景相机图像进行立体图像匹配提供参考。

Aiming at the characteristics of the ChangE′ 3 panoramic camera (binocular camera), an application of image quality evaluation method based on the structural similarity (SSIM) is proposed. After analyzing the ChangE′ 3 panoramic camera imaging principle and the traditional evaluation factors, the method is used for the quality evaluation of image pairs obtained by the panoramic camera. The evaluation factors can be applied to ChangE′ 3 evaluation of panoramic camera image pairs, and the method is superior to the common evaluation factors. Experiments show that this evaluation method as the quality evaluation factor is better than ever before, and it can apply in the assessment of stereo image matching subsequently.
