For the demand for long-range and high-resolution target reconstruction of slow-moving small underwater targets, research on single-photon lidar technology is being carried out. This paper reports sequential multimodal adaptive algorithm based spatiotemporal sequence fusion, which has strong information extraction noise filtering ability can reconstruct depth reflective intensity from complex echo photon time counts spatial pixel relationships. The method consists three steps: data preprocessing, sequence-optimized extreme value inference filtering, collaborative variation strategy image optimization to achieve high-quality in environments. Simulation test results show that outperforms current imaging algorithms, built system achieves lateral distance resolution 5 mm 2.5cm@6AL, respectively. indicates a great advantage sparse counting possesses capability under background light noise. It also provides good solution targets with long-distance high-resolution.
