摘要
According to the image taken by the Chang'e-3 as a near moon image, the elevation value cannot be obtained without a laser altimeter, and a method to estimate the elevation value of the Chang'e-3 is proposed. The method is based on the "Chang'e-2" multi-sensor data and trains the BP neural network model of the corresponding relationship between the feature descriptors and the elevation values in the image. Then, the corresponding elevation values are estimated using the features of the high precision image of the Chang'e-3. Exxperimental results show that the proposed method can reduce the elevation value estimation error to 3.94%. Therefore, the elevation value of the "Chang'e-3" is reliable and can be applied to high-precision moon reconstruction. © 2019, The Editorial Board of Journal of Xidian University.
