Problems solved by technology

However, due to human physical and psychological fatigue, negligence and omissions will inevitably occur, and it is difficult to effectively monitor 24 hours a day
When it is necessary to inquire about a certain illegal video that occurred at a certain time in a certain day, you can only manually fast forward and rewind to browse and query all the video in this time period, verify and transcribe. opportunity

Embodiment Construction

[0033] Embodiment of this distributed intelligent video search system

[0034] The embodiment of this distributed intelligent video search system is for example figure 1 As shown, it includes the monitoring center and 1~n intelligent front-ends distributed in each monitoring point. Among them, three intelligent front-ends that are closer to the monitoring center are directly connected to the monitoring center through a wired LAN, and the rest of the intelligent front-ends are connected to the intelligent center through the Internet, and the number of intelligent front-ends can be increased or decreased as needed. Each intelligent front end has a unique network address stored in the monitoring center. The monitoring center is connected to 2 sets of user terminals through the local area network and the Internet. Such as figure 2 Each intelligent front-end shown includes a camera main body and lens installed in the casing, a video acquisition module, a video processing system...

Abstract

The invention relates to a distribution type intelligent video searching system and a using method. The system comprises a monitoring center and one to n intelligent front ends with unique address. A video processing system of each intelligent front end comprises a microprocessor, a data compressing module, a memory and a video analyzing module for storing N rules of the image feature of an event to be captured. The microprocessor analyzes the real-time video according to the rules, and the video data conforming to the rules are compressed as events and stored by classes. Each intelligent front end is connected with the monitoring center of the rear end through a network. The method comprises the following steps of: determining the monitoring rule; identifying the real-time video, and storing by classifying by each front end; sending the search instruction of time and event numbers by the monitoring center; searching the result according to instructions and sending the results back to the monitoring center by the front end; and requesting the front end to send the required video data according to the results by the monitoring center. The invention can realize quick video search based on events, saves a large amount of storing space and transmitting cost, and greatly decreases the workload of searching.

Description

(1) Technical field [0001] The invention relates to the technical field of video surveillance, in particular to a distributed intelligent video search system and a usage method. (2) Background technology [0002] At present, monitoring cameras are installed in key parts such as banks, intersections, school gates, warehouses, etc., to record the scene video images of each control point in real time. valuable information provided. However, most of the cameras used in existing video surveillance are traditional ordinary cameras, which can only simply complete the function of video collection; their storage is also just simple video recording. In order to facilitate storage and analysis, network cameras have appeared, such as the Chinese utility model patent "Embedded IP Network Smart Camera" with the patent No. 032576617, which provides cameras that can transmit video signals to the monitoring and command center through the Internet. It solves the remote control of the camera...
