In order to make lunar lander autonomous safely on the moon, the potential hazard should be detected. Effective detection of rocks will also provide information for choosing a better landing region which is suitable for exploration. The 2D maximum entropy thresholding method is proposed to segment the shade area from the image, and then the ellipse fitting(More)
Soft landing on the moon is the main target of the second phase of China Lunar Exploration Project. In order to gain guidance accuracy less than 100m, the terrain relative navigation methods should be involved. However the terrain map of lunar with enough resolution will not be available within triennium, the modeling of lunar terrain surface with proposed(More)
In this work, we tentatively propose that the hydrogen-bonding strength EHB (referring to the minimal hydrogen-bonding energy) and its corresponding hydrogen-bond (HB) distance (referring to the optimal HB distance dHB) for simple mono-HB systems have an exponential relationship on the basis of MP2 and DFT computational results. We take a step further and(More)
