LIU Chun 1, SHI Wen-zhong 2, ZHU Shu-long 3. Spatial Visualization of Image Rectification Accuracy Based on Spatial Interpolation[J]. Journal of Remote Sensing, 2004, (2): 143-149. DOI: 10.11834/jrs.20040208.
The existing method of accuracy determination for image recertification mainly from the accuracy estimation of the control points. However
adding the technology of spatial visualization to the accuracy determination and giving the whole expression for that is the main idea of this paper. So the conformal transformation model for the image rectification is taken as a beginning to deduce the relation between the accuracy of an arbitrary point and the accuracy of control points. And according to such relation
the Inverse Distance Power method is used to give the spatial interpolation for the image rectification accuracy
which also achieved the interpolation value in x or y directions and of the point moving accuracy. Based on above
the visualizations of accuracy is put forward to give the detail description for the quality of image rectification. A case image is also adopted in this paper to give the explanation for spatial visualizations of accuracy
and also some helpful conclusion is obtained for its availability.
