  • Method of ortho-rectification for high-resolution remote sensing image
    Patent number: 7865039
    Abstract: A high-resolution remote sensing image is processed through a true ortho-rectification. A totally new idea of H-buffer is provided to store heights of objects on the ground. The ortho-rectification includes a hidden analysis, a hidden detection and a hidden compensation. The process uses polygon patch of a building or a roadway as process unit. In the end, seam lines after hidden compensation are smoothed. The whole process time is reduced in calculations, assures quality of the orthoimage, and meets a requirement of a high-accuracy and high-resolution digital mapping.

  • Method of generating positioning coefficients for strip-based satellite image
    Patent number: 7783131
    Abstract: The present invention provides coefficient for a strip-based image taken by a satellite. By using the coefficient, the absolute error of the image can be made smaller than two pixels. Therefore, the accuracy of the image is high. The present invention can be applied to any pushbroom scanning satellite.
