Embodiment Construction

[0020] This embodiment is a preferred implementation mode of the present invention, and other principles and basic structures that are the same or similar to this embodiment are within the protection scope of the present invention.

[0021] The core principle of the present invention is to try to select a place with a relatively clean background in the monitoring area as a feature tracking area, and use a feature tracking algorithm to track in the selected feature tracking area, thereby finding the best matching point as a tracking target. Tracking shooting and video recording are carried out to the tracking target. In this embodiment, the selected monitoring camera selects the position between the top of the lectern in the image and the bottom of the blackboard or projection screen (if the lower edge of the blackboard or projection screen is below the upper edge of the lectern, Then you can select an appropriate position on the upper edge of the lectern as the extra tracking a...

Abstract

The invention discloses a multi-target automatic tracking method, which comprises the following steps: A, triggering a teacher tracker, starting face detection tracking, finding a face target in a monitoring region, performing video monitoring and recording according to the face target, and saving images in a characteristic tracking region; B, detecting the number of faces in the monitoring region, repeating the step A if one face exists in the monitoring region, and starting motion target characteristic tracking when over two faces are recognized in the monitoring region; C, finding a cluster point which is most matched with the saved information of the characteristic tracking region in a current image in reference to the information of the characteristic tracking region saved in the step A, determining the location of a target once again according to the cluster point, adjusting the teacher tracker by taking the location of the cluster point as the location of the target, and performing video monitoring and recording on the location of the cluster point.

Description

technical field [0001] The invention discloses a convenient monitoring object identification, in particular a multi-target automatic tracking method. Background technique [0002] With the continuous development of video surveillance technology, the application fields of video surveillance are becoming wider and wider, and video surveillance technology is gradually introduced into the education industry to monitor the quality of teaching and classroom effects. In the education industry, for course recording, students and teachers are generally tracked and recorded by multiple cameras. The teacher tracking algorithm in the existing video recording in the education industry is based on face recognition technology or contour recognition technology to identify and track the teacher's position. The image algorithm recognizes the face target within the tracking range. After the target is recognized, the camera will follow The target moves to achieve automatic tracking. Howev...
