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. 本发明属于激光雷达技术领域，涉及一种基于超像素滤波的单光子三维图像重建方法及系统，克服现有后期处理算法如UA算法存在较为严重的图像块效应，且速度难以达到实时化处理要求的问题以及ManiPoP等算法对计算资源的要求成本较高，不能满足实际应用的需求等问题。本发明基于成像物理参数设
