Embodiment Construction

[0049] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0050] In the current target identification method, the characteristic parameters of the target object collected by the camera may change in the case of poor lighting conditions or when the target is occluded. Determining the target object according to the characteristics of the target in the video will obviously lead to the interruption or error of the target tracking, and even cause the target to be tracked to be lost.

[0051] In view of this, in the technical solution proposed by the embodiment of the present invention, the target object is determined according to the extracted characteristic parameters of the object to be identified and the distance from the object to be iden...

Abstract

The embodiment of the invention provides a target identification method and a device, which are used for solving the technical problems in the prior art that easily lead to the loss of the target to be tracked. The object identification method comprises the following steps: extracting at least three video frames from the collected video stream, and extracting the characteristic parameters of the object in each video frame to obtain a characteristic parameter set; Wherein the at least three video frames come from at least three different cameras; Extracting characteristic parameters of an object to be identified in a first video frame and determining a distance between the object to be identified and a corresponding camera; Wherein the first video frame is any one video frame other than theat least three video frames; Discriminating the target object in the first video frame according to the distance, the characteristic parameters, and the set of characteristic parameters.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a target identification method and equipment. Background technique [0002] Intelligent video surveillance is a method of actively monitoring targets. It uses video analysis technology to analyze and process the field of view images monitored by cameras in real time. Once an emergency occurs, it can lock the target (such as pedestrians, vehicles) and pass Control the camera direction, angle of view, etc. to track the target. [0003] The core of intelligent video surveillance is the target detection and tracking method. The current target identification method is mainly to perform pure video technical analysis on the video captured by the camera, and determine the target to be tracked from the captured video according to the characteristics of the target for tracking. [0004] However, the characteristics of the target may change with the change of the shooting environm...
