Device and method for demarcating rearview camera

Abstract

The invention discloses a device and a method for demarcating a rearview camera, relates to the technical field of automobiles and aims at realizing simplicity in structure and easiness in operation and lowering cost. The device comprises a first plumb, a laser casting device, a second plumb and a target device, the first plumb is fixed on a central line of the head of an automobile and is perpendicular to the ground, the laser casting device casts laser to the tail of the automobile to determine a central line of the tail of the automobile, the laser penetrates a first plumb line to determine a central line of the whole automobile, the second plumb is fixed on the central line, of the tail of the automobile, determined by the laser and overhung to the ground to determine a plumb point, at least one reference point, at least one reference line penetrating each reference point and demarcating patterns are arranged on the target device which is placed on the ground at the tail of the automobile, one of the reference point is coincident with the plumb point, and all of the reference lines are parallel to the laser. The device and the method are suitable for being used in the demarcating process of the rearview camera of the automobile.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a calibration device and method for a rear-view camera. Background technique [0002] At present, rear-view cameras are generally installed at the rear of cars to assist drivers (especially novice drivers) in reversing and parking. [0003] When reversing, the rear view camera transmits the image behind the car to the display screen in front of the driver. The driver can intuitively see the real-time video image behind the car. At the same time, the display screen will display dynamic and static auxiliary lines. The driver can Accurately park the car on the parking space according to these displayed information. However, during the process of processing and installation, the rear view camera may deviate from the standard angle of design, which will cause the position of the image transmitted to the display to deviate from the standard position of the image on the display, th...
