A method and apparatus for determining scale information in a probe image navigation process

Abstract

The embodiment of the present application relates to the technical field of deep space exploration, and particularly relates to a scale information determination method and device in a probe image navigation process. The method comprises: obtaining a target time of next output ranging data based on an action occurrence time of distance measurement of a distance measurement device and a working period; sending an image shooting instruction to a navigation image processor in a next preset control period; obtaining a local waiting time before the navigation image processor executes the image shooting instruction based on the target time, a period start time and a local interrupt latch value; after the local waiting time, shooting a lunar surface image below the probe through the navigation image processor, and taking the ranging data output by the distance measurement device at the target time as scale information for matching the lunar surface image with a preset navigation image. The technical scheme of the present application can obtain accurate scale information in the lunar surface image navigation process, and improve the accuracy and success rate of image matching.
