Abstract

The images from the linear array sensors circular scanning perpendicular to orbit have the properties of super wide breadth and high resolution, which also comes with the problem of stereo matching. One method to improve the reliability and efficiency of stereo matching is to search the same one point in linear array. Refer to epipolarity models of linear pushbroom image and plane array remote sensing image, we construct the epipolarity model of the linear array circular scanning image based on a strict imaging model. In this work, we obtain the epiplolarity of the images captured by the linear array sensors circular scanning perpendicular to the orbit using these models. The result shows that the epipolarity of the circular scanning image presents different shapes in different region, including most part with line, a few with parabola and hyperbola in the boundary. These conclusions could provide the progress of three dimension reconstruction.
