Summary: | The invention belongs to the technical field of laser radars, relates to a single-photon three-dimensional image reconstruction method and system based on superpixel filtering, and solves the problems that: existing post-processing algorithms such as a UA algorithm have a relatively serious image block effect and hardly meet the real-time processing requirement in speed, and the algorithms such as ManiPoP are relatively high in requirement cost for computing resources and and cannot meet the requirements of practical application. According to the method, a filtering kernel is designed based on imaging physical parameters, suppression of noise in echo signals and effective utilization of signal photons are achieved based on the superpixel filtering principle, and real-time target high-precision three-dimensional information acquisition is achieved with low calculation cost.
