Embodiment Construction

[0054] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many of the details listed in the specification are only for readers to have a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be implemented even without these specific details.

[0055] like figure 1 As shown, according to an automatic identification and evidence collection target tracking method of the present invention, the tracking method includes the following steps:

[0056] Step 1: Install a cluster of identification and tracking cameras in the forensic space area, and connect each camera to the data processing server. For example, taking an empty square as an example, each area of ​​the square is within the shooting range of the c...

Abstract

The invention discloses an automatic recognition evidence obtaining target tracking method and belongs to the field of image recognition. The polarity of a certain area is scanned and identified through a camera cluster; then, all the cameras are combined; evidence obtaining, recognition and tracking of one area are completed; a tracking recognition processor is independently arranged for each camera; the response delay condition occurring when the camera realizes multi-target tracking is reduced; practice contrast, in this way, the structure is simple, compared with a single server for processing; according to the method, the efficiency is improved by 60%, the tracking processing speed is higher, the position precision is higher, the tracking response is more sensitive through the combination of prediction and real-time tracking, evidence can be obtained in real time, a real-time movement route of a tracking target can be provided, and clues and better case solving are provided for related units.

Description

technical field [0001] The invention relates to the field of image recognition, in particular to an automatic identification and evidence collection target tracking method. Background technique [0002] Photographs have been used to document events, people and places for over 100 years. Digital images are now ubiquitous, thanks to innovative equipment and techniques that have resulted in an ever-increasing number of images captured. Advances in technology have made digital media and digital images our primary source of information, used as evidence in court, as part of medical records, and as financial documents. In practice, digital image forensics can be simply defined as the following process: the first step is to obtain image evidence in suspicious devices, and to search and organize these extracted images more effectively. In the second step, the source attribute and authentication of the image are analyzed; in the third step, the forensic experts give relevant invest...
