Keywords: Mars Express; HRSC; Image Fusion; Linear pushbroom imagery; back projection; best scan line searching Abstract. The High Resolution Stereo Camera (HRSC) on European spacecraft Mars Express is especially designed for topographic mapping of Mars. HRSC can acquire both panchromatic and multi-spectral images simultaneously. The resolution of panchromatic image is higher than that of multi-spectral image. Through image fusion, the high resolution multi-spectral image of Mars can be generated. In this paper, the HRSC raw image is geometrically rectified firstly based on rigorous geometric model. Then, the panchromatic image and multi-spectral image are fused based on IHS transformation. In order to improve the processing efficiency, a fast algorithm for back projection of ground points based on the geometric constraints of the central perspective planar of scan line is proposed. Experiments tested on HRSC images demonstrate our algorithm’s feasibility and efficiency.
