Intelligent target searching, positioning and evidence obtaining system and method based on computer vision

Abstract

The invention provides an intelligent target searching, positioning and evidence obtaining system and method based on computer vision. The method comprises the following steps of guiding photoelectricimage collection equipment to monitor a region where a target is located according to a sensor target detected by a sensor; the image acquisition equipment transmits acquired image information to theimage processing computer for target detection; recording the positions and sizes of all target detection frames in the image; matching the detection frame with the sensor target according to the sensor target information, starting target tracking after the matching is completed, returning the detection frame information to the display control program, and adjusting the photoelectric equipment bythe display control program according to the continuously received detection frame information, so that the target is positioned at a proper position in an image display interface, and obtaining evidences of images and videos. If no sensor except the photoelectric equipment exists, only a photoelectric inspection designated area is used for positioning the target, and the matching, tracking and evidence obtaining processes can still be completed. The alarm target evidence obtaining efficiency is improved, and the trivial operation process of alarm target evidence obtaining is reduced.

Description

technical field [0001] The invention relates to the field of electronic information, in particular to a computer vision-based intelligent target search, location and evidence collection system and method. Background technique [0002] The problem of water area governance has a long history. In the course of historical development, the masses of the people are constantly fighting fiercely against water area pollution, illegal crimes and other issues. In recent years, the state and society have further awakened their awareness of enhancing ecological civilization construction, and have gradually increased their efforts to crack down on crimes. Relevant policies have been introduced and implemented one after another. The importance of water governance is self-evident. The difficulty and complexity of governing oceans, rivers, lakes, etc. are coming head-on, requiring a lot of manpower and material resources, and the demand for intelligent waters governance is becoming increasin...

Problems solved by technology

[0003] However, most of the optoelectronic equipment currently used for water area monitoring collects evidence for abnormal targets, or finds abnormal targets through the monitoring system, and manually takes the next step to obtain evidence. or can only take pictures with a large field of view for a certain area, and cannot flexibly adjust the size of the field of view, making it difficult to lock the target; or cannot accurately and efficiently connect the target detected by the photoelectric device with the sensor target, and the forensic information is one-sided or match error rate is too high

All of the above problems will cause certain troubles and obstacles to further law enforcement operations.
