N2 - In this paper, we present an alternative parametric active contour (APAC) model for 3D lunar crater detection with shadow and overexposure problem. Compared with the traditional parametric active contour model, the main difference is that we construct a Gaussian attractive force field between two initial curves for each crater proposal, which enables the two initial curves to mutually convey message to each other and avoids local optimum. In addition, we introduce the elevation information estimated from CCD stereo images into the external energy term of the APAC model, which helps to remove false craters by providing the geometric properties of craters. The proposed method is evaluated on eight pairs of stereo images with different numbers, scales and illuminations captured by Chang'E-I satellite, which demonstrates its effectiveness and efficiency.
