Research Progress on Key Technologies of Target Detection for Laser Imaging Guidance

With the increasing demand for precision strikes in modern warfare, the laser active imaging guidance technology has become a key technology for enhancing the effectiveness of guided weapons due to its anti-interference and high precision, etc. Focusing on the target detection technology in the field of laser active imaging guidance, this paper first expounds the principle of laser active imaging. The three- dimensional information of a target is obtainsed through the emission and reflection of laser beams, providing multi-dimensional data support for target detection. Secondly, it summarizes the research status of target detection technologies suitable for active imaging laser guidance from two aspects: the target detection technology after projecting the three-dimensional information into the two-dimensional information and the target detection technology for three-dimensional point clouds. On this basis, it points out that the core challenge in this field is how to achieve real-time and high-precision target detection in complex and large-scale environments. Finally, it looks forward to the future development trend of relevant technologies. The purpose is to provide references for the further development and application of target detection technology in the field of laser active imaging guidance, and offer new ideas and methods for the further development of this technology.
