Image alignment device for convex surface reflecting mirror-based driver video monitoring system

Abstract

The invention discloses an image alignment device for a convex surface reflecting mirror-based driver video monitoring system. The image alignment device comprises a driver video monitoring system and a camera electrically connected with the same, the camera is connected with a fixed support rack via a universal adjusting mechanism, the camera is mounted on a front end of a driver cab via the fixed support rack, and a convex surface reflecting mirror is arranged right below the camera. The convex surface reflecting mirror beside a camera lens is adjusted in such a way that a driver face image reflected by the reflecting mirror is consistent with an image obtained via the camera, only the driver face image in the reflecting mirror needs to be observed at this time so as to adjust a pitch angle and a rotation angle of the camera, the driver face image is enabled to be at a central position of the reflecting mirror, and then image alignment can be realized; the image alignment device is simple in structure and enables convenient aligning operation.

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 a convex mirror. Background technique [0002] With the increasing number of cars and the continuous extension and development of the road system, various traffic accidents are also increasing. The increasingly severe road traffic safety situation not only causes a large number of people and property losses, but also leads to more social problems. produce. According to the investigation and statistics of accident causes, more than 75% of traffic accidents are related to driver factors, such as driver fatigue driving, distraction, smoking, drinking, mobile phone, etc. , an important means to ensure driving safety, and the driver video monitoring system has basically become the standard configuration of commercial vehicles such as two passengers and one d...
