Photographic method testing system for Motorbicycle front shining lamp distritution performance based on C/S mode

Abstract

The present invention discloses an image shooting method testing system of the light distribution property of the headlights of the motorcycle based on C/S mode. The hardware part of the system includes a PC machine and a displayer which are positioned in the workshop, a workpiece rotating table which is positioned on the front of the workpiece for placing the lamps to be detected, a testing curtain positioned on the wall of the darkroom, a CCD vidicon positioned on the five-dimensional adjusting frame and oppositing to said testing curtain and an industrial personal computer which is connected to said CCD vidicon and is provided with an image collecting card inside; a rectangular light inlet window positioned on the wall between the darkroom and the workshop; the industrial personal computer is positioned on the PC machine of said workshop through netting twines; the software part of the system is the self-written measuring programs aiming to the system in the present invention. The advantages of the present invention are: the production cost is low; the detecting speed is fast; the light type photos of the lamps can be storied and self-adapting collimated; the system is an important reference of the disqualification factors and the improvement of the products for analysing the products for the corporations.

Description

technical field [0001] The present invention relates to a vehicle detection device, more specifically, the present invention relates to a light distribution performance test system for motorcycle headlamps Background technique [0002] With the high-speed development of China's economy, the penetration rate of motor vehicles is getting higher and higher, and the headlights, as their important safety components, are getting more and more attention. But for now, the quality of existing headlight products is not satisfactory, and among all kinds of motor vehicles, the problem of motorcycle headlights is particularly prominent. [0003] China is a big country of motorcycles. According to statistics, the output of motorcycles in 2005 has exceeded 18 million. However, the results of spot checks show that the passing rate of light distribution performance of motorcycle headlights is less than 50%, which is an important safety hazard. One of the reasons for this phenomenon is that...
