Visual surveillance system for law enforcement or police case investigation is different from traditional application, for it is designed to monitor pedestrians, vehicles or potential accidents. Visual surveillance risk is defined as uncertainty of visual information of targets and events monitored in present work and risk entropy is introduced to modeling the requirement of police surveillance task on quality and quantity of vide information. the prosed coverage model is applied to calculate the preset FoV position of PTZ camera.
Video surveillance is an important security technology, which is widely use in public areas and police detection utilizing video surveillance system is a powerful method in the police investigation that must answer the question of five W’s on crim. In this paper, a HWMSE system is designed to solve problems in case detection based on the theories of metasynthesis from qualitative to quantitative. The proposed HWMSE system is constituted of four components: Database sub-system of case information and knowledge, man-machine combination toolsets of video analysis, deduction simulation system based on crime behavior modeling and case analyzing platform.
