Problems solved by technology

Based on the geometric and mathematical knowledge of two points and one line, this method can determine the centerline of the car body, but the two points it marks are only the extended marks of the reference point of the center of the car body. If an error occurs during the extension process, the centerline is not calibrated correctly
At the same time, in principle, the extension of the center reference point of the car body is based on the vision of the human eye. The position

Embodiment Construction

[0055] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is said to be "fixed" to another element, it may be directly on the other element, or there may be one or more intervening elements therebetween. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The terms "vertical", "horizontal", "left", "right", "inner", "outer" and similar expressions are used in this specification for the purpose of description only.

[0056] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention. Terms used in the description of the pre...

Abstract

The invention relates to the technical filed of vehicle maintenance and device calibration and discloses a calibration device and method of the center line of a vehicle body. The calibration device comprises a support device and laser devices. The support device comprises a horizontal graduation ruler, and the laser devices are used to be installed on the vehicle body and emit laser beams to the horizontal graduation ruler. When the calibration device of the center line of the vehicle body is used, the two laser devices are arranged on vehicle wheels of the two sides of a vehicle, and two laser beams which are emitted at equal intervals with the vehicle wheel as reference points, are irradiated on the horizontal graduation ruler; according to the scale of the horizontal graduation ruler, the support device can be moved to an appropriate position, and the center line of the vehicle can be conveniently calibrated.

Description

【Technical field】 [0001] The invention relates to the technical field of vehicle maintenance and equipment calibration, in particular to a vehicle body centerline calibration device and method. 【Background technique】 [0002] In the field of automobile maintenance, such as four-wheel alignment, Advanced Driver Assistant Systems (ADAS) calibration, etc., it is necessary to calibrate the centerline of the car body to facilitate the placement of subsequent calibration equipment, including equipment centers and car body centers Calibration of the centerline of the vehicle body is indispensable for alignment, distance between the equipment and the vehicle body, and vertical center plane between the equipment and the vehicle body. [0003] In the process of realizing the present invention, the applicant found that the main drawbacks of the existing centerline calibration method are as follows: [0004] 1. The calibration is not rigorous and the error is large. Existing calibrati...
