Abstract

The invention provides a searching method, a searching device and a searching system of a target object. The method comprises the steps that an initial target image which is matched with the target object is searched for in a current video source, and standard image characteristic information of the target object is calculated in the initial target image; the path information of the target object in each video source is searched for according to the standard image characteristic information, the appearance sequence of the target object in each video source is searched for, and a video source locus list of the target object is created; the movement locus of the target object is traced out in an electronic map according to the relative position relation of the video source locus list of the target object and each video source. According to the embodiment of the invention, the movement locus of the target object in each video source is accurately and rapidly searched for by utilizing the searching method of the target object, the target object is automatically searched for across the video sources, the efficiency and the precision of searching for the target object by a camera shooting system are improved, and the practicability of the camera shooting system is greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a method, device and system for searching a target object. Background technique [0002] Now, when many cities are building "safe cities", most of them use the camera monitoring system to visually observe the situation in various locations in the city. irreplaceable advantage. [0003] In the prior art, the camera in the video surveillance device records images to generate a video source. When people need to find out the target object from the video source, they usually use the extraction and combination technology of the key frame of the video image, based on the color of the target object, Image feature information such as shape, texture, and motion direction extracts the target object from the image background of the video source, then analyzes the behavioral characteristics of the target object, and realizes target recognition and comparison based on these features....
