According to the terrain features of the tailings dam, the water boundary image of the tailings dam is obtained by the acquisition of the water. The contour recognition, threshold segmentation, and watershed algorithm can be used to retrieve the boundary between dry beaches and water surface. Analyze and deal with the image pixel coordinates, the most accurate pixel coordinates of waterline can be...
Nowadays star sensor technology used in aircraft attitude measurement has become more and more popular for its high precision, light weight, without attitude accumulation errors and other advantages. In order to enhance the accuracy of star sensor, it is critical to make efforts to promote the precision of star image locating. High precision star image locating method mentioned in this article includes...
A new method of affine object recognition and affine parameters estimation is presented. For a real-time image and a group of templates, firstly, we segment the object regions in them and compute their covariant matrices. Secondly, normalize the ellipse regions defined by covariant matrices to circle regions to get rotational invariants, and compute the similarity function value between rotational...
