The method of depth inversion in airborne laser depth measurement system is analyzed. The method of wave tidal correction and the method of using parameters measured by dynamic global positioning system phase ambiguity solver (KGPS OTF) are deduced (without correction) . Through comprehensive analysis of various parameters that affect the accuracy of airborne laser sounding, and using the technical parameters of airborne lidar, the precision of water depth extraction of the two methods is quantitatively estimated. The results show that the accuracy of the wave tide correction method is slightly higher than that of the no correction method, but no correction method is more simple and clear, and the data post-processing calculation can be greatly reduced
