Abstract: With the rapid development of the aerospace satellite industry, the manufacturing and launch of satellites have entered a phase of rapid expansion. Concurrently, as mass satellite production takes precedence, the posture measurement of satellite sensors is progressively advancing towards automation and intelligence. In response to the requirements of automated attitude determination and control measurement technology for large-scale satellites, corresponding technical methodologies have emerged. Building upon the existing automated attitude determination and control measurement technology for mass-produced satellites, this paper conducts a thorough analysis of the optical crosshair extraction model and automated search algorithm within the current models. Addressing identified shortcomings, the paper proposes novel optical crosshair extraction and automated search algorithms, significantly enhancing the efficiency of satellite automated attitude determination measurements.

Key words: satellite automatic measurement, cross silk image recognition, automatic search of collimated cubic mirror, visual guide, graph convolution
