Abstract

A detector for checking the grading performance of motor vehicle headlight consists of two reference columns for positioning, three digital cameras, detection screen, driving mechanism of screen and computer. It features setting screen driving mechanism in front of motor vehicle, two digital cameras on top of screen with shooting range to cover planar width defined by two positioning reference column, another digital camera on one of two said columns or near center of line connected on the ground between said two columns. The detecting method is also disclosed.

Description

1. Technical field: [0001] The invention relates to a motor vehicle headlamp tester and a detection method for detecting the light distribution performance of a motor vehicle symmetrical light headlamp, and belongs to the innovative technology of the motor vehicle headlight tester and the detection method. 2. Background technology: [0002] According to GB7258-2004 provisions of motor vehicle operation safety technical conditions, the beam irradiation position requirements: [0003] 1) When inspecting the irradiation position of the low-beam beam of the headlamp, when the headlight is irradiated on the screen at a distance of 10m, the height of the corner or midpoint of the cut-off line of the low-beam beam of the passenger car headlamp should be 0.7H to 0.9H H (H is the reference center height of the headlight, the same below), other motor vehicles (except tractor transport unit) should be 0.6H ~ 0.8H. For motor vehicles (except for motor vehicles equipped with one headlam...
