Combined Stereo Location Among Multi-sensor Remote Sensing Images

  • We described the geometric aspects and the mathematical treatment for stereoscopic image pair composed of IKONOS,SPOT4 satellite images and airborne SAR images.First,the rational function model of IKONOS imagery,collinearity equations with line central projection for SPOT4 imagery and F.Leberl model for SAR imagery as well as methods to simultaneously determine or refine individual parameters of these models were briefly reviewed.Firstly,a straight-forward single-step procedure was developed,which follows the philosophy of photogrammetric bundle adjustment techniques.Secondly,the combined stereo location model with multi-sensor remote sensing images was constructed from these geometry models.The stereo location is the procedure of determining the ground coordinates of a ground point from a pair of corresponding homologue points in the combined stereoscopic pair.Experimental results show that it is feasible to realize combined stereo location with multi-sensor images.The accuracy of combined stereo location is close to classical stereoscopic pairs in some conditions.
