Problems solved by technology

[0011] (1) Video analysis technology. This technology uses the image analysis camera to drive the tracking of the shooting camera by the change of the area image before and after. This technology will cause inaccurate tracking when the lights and curtains on the scene change. It is the case of no tracking; it is impossible to achieve the effect of automatic tracking and shooting of multiple people on the podium and the effect of teachers walking to the front of the student area, and cannot support large classrooms, etc.
[0012] (2) Infrared detection technology, this technology needs to install red infrared emitting strips and infrared receiving devices around the class

Embodiment 1

[0079] see Figure 4 As shown, an intelligent tracking device based on radar detection includes: behavior point sensing device, positioning controller, behavior detection analyzer, behavior detection and analysis control panel, behavior control publisher, data storage, power interface, network interface, Connect cables, cable protectors.

[0080] The behavior point sensing device is composed of a laser emitting device and a laser receiving device. The laser emitting device and the laser receiving device are arranged correspondingly. The laser emitting device is used for continuously emitting laser lines, and the emitting frequency is 25-50 times per second. The behavior point sensing device adopts the following structure:

[0081] The behavior point sensing device is placed at the rear or side of the classroom. The laser emitting device emits pulse waves continuously in actual use. The laser pulse waves hit the high-speed rotating mirror and emit pulse waves in all direction...

Embodiment 2

[0107] Compared with Embodiment 1, the behavior point sensing device adopted in Embodiment 2 adopts the following structure:

[0108]The behavior point sensing device is placed at the rear or side of the classroom, and the viewing angle of the installation position is convenient for observing the students in the classroom and the teacher on the podium; one or more laser emitting devices correspond to a laser receiving device, and a large number of laser emitting devices and The laser receiving devices are densely distributed on the outer surface of a sphere. These laser emitting devices emit laser lines from the center of the sphere to the surroundings. Each laser line is emitted by the laser emitting device and received by the laser receiving device; the spherical shape composed of the laser emitting device and the laser receiving device The structure has an opening at the bottom, which is circular, for mounting the support frame and cables.

Embodiment 3

[0110] Different from Embodiments 1 and 2, the behavior point sensing device adopted in Embodiment 3 adopts the following structure:

[0111] Laser emitting devices and laser receiving devices are placed on the walls around the classroom, one laser emitting device corresponds to one laser receiving device, a large number of laser emitting devices and laser receiving devices are densely distributed on each wall, and each laser line is composed of The laser emitting device emits and is received by the laser receiving device. The laser line emitted by the laser emitting device is perpendicular to the wall on which the laser emitting device is installed; the densely distributed behavior point sensing devices form a horizontal and vertical scanning grid, forming a Scanning the plane grid, when an object blocks any scanning line in the grid, the two-dimensional coordinates can be determined according to the blocked horizontal and vertical laser lines. A cable port is installed at th...

Abstract

The invention discloses radar detection and laser radar technology based intelligent tracking equipment and intellectualized behavior detection analysis method. The radar detection based intelligent tracking equipment comprises a positioning controller, a behavior point sensing device, a behavior detection analyzer, a behavior detection analysis control panel, a behavior control publisher, a data storage device, a cable protection device and the like, wherein the behavior point sensing device comprises a laser transmission device and a laser receiving device. The radar detection based intelligent tracking equipment can detect behaviors of teachers and students in a classroom in real time and publish the behaviors to the behavior control publisher and meanwhile performs human-machine interaction through the behavior detection analysis control panel, wherein the cable protection device can be applicable to cables in different length and can conveniently and effectively protect the cables. According to the radar detection based intellectualized behavior detection analysis method, contrastive analysis can be performed according to data in the storage device and data collected by the radar detection based intelligent tracking equipment, so that the behaviors of the teachers and the students and positions of the behaviors can be obtained in real time and displayed in the behavior control publisher.

Description

technical field [0001] The present invention relates to an intelligent tracking device based on radar detection and its positioning method, in particular to an intelligent tracking device based on laser radar detection and intelligent behavior detection for the recording of excellent courses in the classroom, real-time detection and analysis of teacher and student behavior Analytical method. Background technique [0002] Intelligent tracking equipment is mainly through infrared detection, video analysis, ultrasonic and other equipment. After detection, induction and other processing, it drives the camera to rotate, zoom out, zoom in, focus, etc., and through related strategies, the teacher's camera, the student's camera, VGA Images and other screens are automatically synthesized into standard video files. [0003] One of the purposes of the smart tracking device is to record the video of the high-quality courses, that is, when no one is on duty, the teacher's camera will au...
