  • 摘要:This paper focuses on automatic identification of lunar craters in the context of safe landing siteidentification. Craters appear on the lunar surface in high density and are the most interesting features of any planetarysurface. In this paper, the technique presented is for crater detection and fitting an ellipse after determining the positionand orientation of the craters. Image smoothing is optional as it is done to extract crater features greater than a specifiedsize from the image. Morphology gradient technique is used in this approach to extract edges belonging to craters only.Ellipse is fitted on the edge map using least square error and square completion method. This algorithm is tested ondifferent datasets of Chandrayaan-1 TMC and LRO (NAC) and results are compared with manually detected craters.
