Photon counting laser radar data ground elevation inversion method

The invention belongs to the technical field of photon counting laser radars, and particularly relates to a photon counting laser radar data ground elevation inversion method. The method comprises the following steps: firstly, acquiring original photon data of the photon counting radar, extracting noise photons in the original photon data, and removing the extracted noise photons to obtain signal photons; then, extracting ground photons from the signal photons by adopting a cloth simulation method; and finally, inverting the ground elevation. Experiments show that the method can effectively extract signal photons so as to obtain high-precision ground elevation curves under different land coverage and topographic conditions, the average error and root-mean-square error of the inversion ground elevation are low, the inversion precision is high, and the method is suitable for large-scale popularization and application. An effective solution is provided for estimating the ground elevation by using photon counting
