| description | The invention provides an asteroid striking surface determination method and device, equipment, a medium and a product, and belongs to the technical field of asteroid defense. According to the embodiment of the invention, based on the attitude of the asteroid, the N geometric surfaces of the spacecraft which can be hit to the asteroid can be determined from the three-dimensional model; and under a set coordinate system, based on a first unit vector of the geometric surface in the first direction, a second unit vector of the geometric surface in the second direction, a first angle between the second unit vector and the third velocity vector, and a collision model of the spacecraft and the asteroid, determining a target striking surface from each geometric surface. Namely, according to the embodiment of the invention, the geometric surface which can be hit by the spacecraft under any attitude of the asteroid can be determined, and the benefit generated by hitting each geometric surface by the spacecraft can be |
