Image registration device based on driver video monitoring system in circuit control

Abstract

The invention discloses an image registration device based on a driver video monitoring system in circuit control. The device comprises a driver video monitoring system and a camera connected with the driver video monitoring system electrically. The camera is connected with a fixed support frame by a universal adjusting mechanism and is installed at the front end of a cab by the fixed support frame. A signal output terminal of a processor of the driver video monitoring system is connected with a light-emitting diode by a control circuit; the processor is used for determining whether a face image shot by the camera is located at the middle of a field of view of the camera; and the control circuit is used for converting an image registration state into a high / low-level signal. If the face image is located at the middle of the field of view of the camera, the control circuit outputs a high-level signal and the light-emitting diode does not emit light; and otherwise, the control circuit outputs a high-level signal and the light-emitting diode emits light. Therefore, whether the camera is aligned with the face can be determined only by observing whether the light-emitting diode lights up and then the angle of the camera is adjusted by the camera adjusting mechanism. Moreover, the device having a simple structure can be adjusted conveniently.

Description

technical field [0001] The invention belongs to the technical field of driver video monitoring systems, and in particular relates to an image alignment device and alignment method of a driver video monitoring system based on circuit control. Background technique [0002] With the continuous strengthening of government departments' emphasis on road traffic safety management and the continuous improvement of vehicle networking technology and vehicle intelligent safety level, driver video monitoring systems have been widely used in passenger vehicles, freight vehicles, buses, special transport vehicles, etc. on the model. The system mainly collects the driver's facial image through the camera, and applies image processing technology to realize the monitoring content such as fatigue driving detection, driver's attention state detection, smoking, dialing / receiving mobile phones, etc. It can effectively prevent traffic accidents and ensure driving safety. [0003] During the equ...
