This article intends to solve the matching problem of 2C level lunar images by Chang'E-1 (CE-1) lunar probe satellite. A line-scanner image matching method is proposed which represents deformation by the quadric function along the camera motion direction and bases on the deformation model for a relief terrain's imaging on sensors of the satellite borne three-line scanner camera. A precise matching is carried out for the normal view, the frontward view, and the backward view images of the CE-1 by combining the proposed method with the standard correlation method. A super-resolution (SR) reconstruction algorithm based on the wavelet interpolation of non-uniformly sampled data is also adopted to realize SR reconstruction of CE-1 lunar images, which adds the recognizable targets and explores CE-1 lunar images to the full.
