ACTA OPTICA SINICA(2021)
摘要
At present, the number of illegal intrusion incidents in the field of public security is increasing rapidly, so new sensing technologies are urgently needed to detect illegal intrusion events. Aiming at the bottleneck problems of accurate positioning, accurate identification, and multi parameter fusion, Tianjin University, Tiandy Technologies Co., Ltd., and other research institutions have proposed the key technology for event recognition and perception of photoelectric information. It closely integrates the advantages of video monitoring and distributed optical fiber sensing technology. This technology has realized all-weather and full coverage monitoring and recognition of abnormal events in key areas through the optical time and frequency domain distributed disturbance positioning technology, interference signal pattern recognition technology, superstar optical image recognition technology, video capture analysis and recognition technology, multi parameter sensing perception and fusion technology, active polarization tracking and sensing technology, etc. This paper focuses on the research progress of key technologies of event recognition and perception in photoelectric information events.
