Problems solved by technology
However, due to the shape of the visor and the installation position of the current low beam, there are often shapes that meet the light type, but although the brightness in the dark area of the light spot is weaker than that at the bottom right, there is still a certain intensity and cut-off line. The transition zone of the bright band is wide, the inflection point is unclear, or there are bright spots in the dark area, which will cause some bad effects on the other driver and affect the driver's sight, thus causing traffic accidents

The invention discloses an automobile headlamp detector. The main content is that a pedestal trolley is installed on guide rails. A stand column is installed on the pedestal trolley. The lower end of a right guide column and the lower end of a left guide column are installed on the pedestal trolley. The upper end of the right guide column and the upper end of the left guide column are installed at the top end of the stand column. A supporting base is installed on the right guide column and the left guide column. A light receiving box body is fixedly installed on the supporting base. A display device is installed on the light receiving box body. A control device is installed at the top end of the display device. A front Fresnel lens is installed on the light receiving box body. A semi-reflecting and semi-transmitting lens is installed at the lower left side in the light receiving box body and parallel to a reflecting lens. The reflecting lens is arranged at the upper left side in the light receiving box body. A CCD camera is arranged at the right side of the semi-reflecting and semi-transmitting lens. An imaging screen is close to the right side surface of the light receiving box body and close to the bottom end. A four-quadrant photocell and a rear Fresnel lens are arranged at the right side of the reflecting lens and close to the top end. The four-quadrant photocell is arranged at the right side of the rear Fresnel lens.
Description
Technical field [0001] The invention relates to the technical field of automobile lamp detection, in particular, to an automobile headlamp detector. Background technique [0002] In the course of driving, due to the vibration of the car, the installation position of the headlight components may change, thereby changing the correct irradiation direction of the headlight beam and producing a non-standard light shape. At the same time, the bulb of the headlamp will gradually age during use, and the reflector surface will also be contaminated to make its light-gathering performance worse, resulting in insufficient brightness of the headlamp. These changes will cause the driver to be confused about the road ahead, or cause the opposing driver to dazzle when meeting with the oncoming car, which may cause a traffic accident. Therefore, the luminous intensity and direction of the headlights are the key factors that affect the driving safety of the car and must be tested regularly. [000...
