The Lunar Orbiter Laser Altimeter (LOLA) is currently the largest and most accurate laser altimeter in lunar exploration, which can provide geographical control for other lunar products. However, due to the uncertainty of orbit determination and laser direction deviation, there are geographic positioning errors on some laser profiles. In view of these abnormal orbit data, an improved laser self-constrained adjustment method is proposed in this paper. Firstly, the laser profile that is too different from the surrounding terrain is identified as an abnormal orbit based on the slope, and the other orbits are used as references for self-constrained orbit adjustment based on the point density (the appropriate adjustment strategy is automatically selected according to the reference point density). Finally, the two types of orbit data are merged and the final adjustment is made, and then it is used as the corrected result. The results of cross point analysis show that this method can effectively correct the anomalous orbit and improve the data accuracy.
