Method and system for automatically finding and registering target in surveillance video

Abstract

The invention relates to the field of intelligent security protection, and discloses a method and system for automatically finding and registering a target in surveillance video. The method system for automatically finding and registering the target in the surveillance video comprises the following steps that the target is detected in a video stream; feature extraction is carried out on the detected target so that the target feature is obtained; whether the target feature has already existed in a target list or not is judged, if yes, the frequency of appearance of the target feature is increased by one, and if not, the target feature is added into the target list, and the frequency of the appearance of the target feature is set as one; whether the frequency of appearance of the target feature exceeds a preset threshold value or not is judged, and if yes, the target feature is arranged in an alarm list in a registration mode. On the basis of a comparison system, the key target which appears repeatedly is automatically found and automatically arranged in the alarm list in a registration mode to serve as an object which is analyzed and processed subsequently in a focused mode, and the common comparison system is more intelligent and practical.

Description

technical field [0001] The invention relates to the field of intelligent security, in particular to a method for automatic discovery and automatic registration of targets in surveillance video. Background technique [0002] Real-time comparison is an application method of intelligent video analysis technology. It detects the target from the video stream and compares it with the alarm list registered in the system in advance. When the set threshold is reached, an alarm is issued. Its typical application is bayonet The way is to set up the system in important passages to capture the images of past targets in real time and compare them with the registered alarm list in real time to alarm, such as the vehicle bayonet system used in traffic arteries and the face recognition at railway stations, bus stations, entrances and exits of important places, etc. bayonet system, etc. [0003] Alarm list: compare the list to be compared in the system in real time, and compare the detected ...

Problems solved by technology

[0005] The real-time comparison application is one of the typical application methods in the field of intelligent security. In the traditional real-time comparison system, the alarm list is mostly added to the system through registration (including batch import or incremental update from other systems), and the important The flow of people in the place is very rapid, and the traditional alarm list registration method alone cannot meet the requirements of intelligence and real-time
