Embodiment Construction

[0040] In this specification, the terms front, rear, top, and bottom refer to the front-rear direction of the vehicle. The axes X, Y, Z correspond respectively to the longitudinal axis (from front to the rear), the transverse axis and the vertical axis of the vehicle.

[0041] figure 1 A plan view of a motor vehicle 1 is shown, equipped with a front camera 2 , a rear camera 3 , a LIDAR remote detection device 4 , and headlights 5 and 6 . ADAS type technologies can use these different electric and electronic components. For this, it is necessary to calibrate it, usually using predetermined geometric reference marks defined by alignment areas on the ground, usually using mats that do not appear to be able to adapt to different vehicle templates. Disadvantages that are not matched and difficult to locate accurately. Such geometric reference marks can be predefined in the computer to be used for calibration.

[0042] The present invention proposes a geometric reference device ...

Abstract

The present invention relates to a method of mounting a marking area on a substantially flat level ground for calibrating a camera of a motor vehicle, the method comprising: - positioning the vehicle on the ground with the wheels aligned with the longitudinal axis (X) of the vehicle parallel, - positioning a geometric reference device on the ground around the vehicle, said reference device comprising a set of separate elongated plates forming scales (11-14), each scale (11-14) having an at least partially positioned A lower flat surface on the ground and sufficiently rigid not to deform on said lower plane, positioning is achieved by placing the scale of the adjustment device on the ground at a predetermined distance from the vehicle according to a predetermined schematic. The invention also relates to a corresponding device.

Description

technical field [0001] The present invention relates to a method of mounting a geometric reference marker on a substantially flat level ground for calibrating electric and / or electronic components of a motor vehicle and suitable equipment. Background technique [0002] The use of new embedded technologies such as ADAS (Advanced Driver Assistance Systems) technology in motor vehicles results in new electrical / electronic component calibration and / or learning operations performed by motor vehicle instructors both in the factory and after sale. These operations may consist of physical and / or electronic adjustments of one or more components such as cameras (optical vision), radar / range finders (electromagnetic waves), sonar (sound waves), especially with infrared LIDAR (light detection and ranging) remote detection devices, lasers (light amplification by stimulated emission of radiation); light (beam) projectors. [0003] These learning operations, which are essential to the cor...
