Embodiment Construction
[0058] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution, and provides detailed implementation and specific operation process, but the protection scope of the present invention is not limited to the present invention. Example.
[0059] like figure 1 As shown, a kind of fast star map image star point extraction method of the embodiment of the present invention comprises the following steps:
[0060] S101: Segment the star map image: use a multi-window sampling method to determine the threshold in the star map image threshold segmentation method, and separate the star point pixels from the background pixels according to the idea of image segmentation;
[0061] S102: Coarsely locate the observed star points: learn from the idea of clustering algorithm, first classify some star point pixels, regard the pixels belonging to the same star point as a categ...
