Abstract

The invention discloses a simulation image generation method and device. The method comprises the following steps: determining a working imaging model and camera parameters of a camera; determining acamera imaging area and a pixel imaging area of the camera according to the digital topographic map of the target object, the working imaging model and the camera parameters; and generating a simulation image of the target object according to the pixel value of the pixel imaging area, the simulation image at least comprising a camera image oriented to a deep space exploration task digital simulation system. According to the invention, the technical problem that the camera image for the deep space exploration task digital simulation system cannot be effectively obtained in the related technology is solved.

Description

technical field [0001] The invention relates to the field of deep space exploration image simulation, in particular to a method and device for generating a simulation image. Background technique [0002] In order to control the control risk of extraterrestrial celestial body detection, during the preparation process or task execution process of extraterrestrial celestial body detection missions, it is necessary to carry out digital or semi-physical simulation of the surface environment of extraterrestrial celestial bodies, which is used for verification and rehearsal of several links of mission control. [0003] Take the Chang'e-3 mission as an example. The Chang'e-3 mission is the first soft landing of an extraterrestrial object implemented by our country, and the first remote operation of the patrol device to conduct a lunar inspection. On the basis of the great technological leap achieved by the Chang'e-3 mission, in order to effectively reduce the risk of project impleme...
