Embodiment 1

[0022] The plane resolution of the lunar surface imaging sensor is 0.1m, and the height information of every point on the lunar surface at an interval of 0.1m can be obtained through the lunar surface imaging sensor. Such as figure 1 As shown, the area occupied by the lunar probe in the case of landing is defined as the unit area S, and the center of the unit area S is defined as the landing center. The width of each grid in the figure is 0.1m. If the unit area S is 0.2m×0.2m, then S has height data of 3×3 points in total.

[0023] The point on the lunar surface corresponding to the current lunar probe is the initial judgment point of the landing center, and the landing center is moved point by point from the inside to the outside in a clockwise spiral form, such as figure 2 As shown in , all the height data in the unit area S where each landing center is located are calculated to determine whether the landing area of ​​the corresponding unit area is safe.

The width of each grid in the figure is 0.1m. If the unit area S is 0.2m×0.2m, then S has height data of 3×3 points in total.

[0108] The point on the lunar surface corresponding to the current lunar probe is the initial judgment point of the landing center, and the landing center is moved from the inside to the outside in a circular manner, such as Figure 4 As shown in , all the height data in the unit area S where each landing center is located are calculated to determine whether the landing area of ​​the corresponding unit area is safe.

Abstract

A method for scan-selecting safety landing region of moon craft at hovering stage includes obtaining 3-D information of moon surface by utilizing sensor of moon surface-imaging defining region occupied by moon craft-landing as unit area being defined as landing center, moving said landing center as per fixed distance from inside to outside to judge whether each landing region on landing center issatisfied with landing condition or not and moving said landing center continuously to make judgment if it is not or otherwise moving moon craft to relevant position for landing.

Description

technical field [0001] The invention relates to the technical field of selecting a safe soft landing area for a lunar probe according to lunar topography information during a hovering phase. Background technique [0002] The Lunar series of lunar probes of the former Soviet Union and the Surveyor series of lunar probes of the United States did not judge the safety of the landing area before landing on the moon, and directly landed softly on the moon; Astronauts come to select the landing area to ensure a safe landing. For the unmanned lunar soft landing probe, in order to ensure the safety of landing, the control system must have the ability to obtain information on the lunar surface and select a safe landing area. Japan's SELENE-B detector is equipped with a scanning laser viewfinder and image sensor, the purpose of which is to image the lunar surface before landing and detect obstacles to ensure landing safety. However, there are no related reports on the selection metho...
