Embodiment 1
[0047] figure 1 The implementation flow of the method for extracting the star point centroid of the star sensor multi-channel image provided by the first embodiment of the present invention is shown. For the convenience of description, only the parts related to the embodiment of the present invention are shown, and the details are as follows:
[0048] In step S110, the connected domain is marked for each pixel in each row in the multi-channel image, and the marked value of each pixel is determined.
[0049] The embodiments of the present invention are applicable to star sensors and the like, where processors are installed in these star sensors to extract the centroids of star points of multi-channel images, and can accurately extract the centroids of star points located at the boundary of two channels.
[0050] When marking a pixel as a connected domain, the pixel grayscale of the pixel is used.
[0051] The multi-channel CMOS sensor of the star sensor outputs multiple image ...
Embodiment 2
[0076] Figure 5 A structural block diagram of the star sensor 100 provided by Embodiment 2 of the present invention is shown, and for convenience of description, only parts related to the embodiment of the present invention are shown.
[0077] refer to Figure 5 , the star sensor 100 may include one or more of the following components: a processing component 101 , a memory 102 , a power supply component 103 , a multimedia component 104 , an audio component 105 , a sensor component 107 and a communication component 108 . The above-mentioned components are not all necessary. The star sensor 100 can add other components or reduce certain components according to its own functional requirements, which is not limited in this embodiment.
[0078] Processing component 101 generally controls the overall operations of star sensor 100, such as operations associated with display, telephone calls, data communications, camera operations, and recording operations, among others. The proces...
