Abstract

The invention relates to the field of automotive lamp detection, in particular to an automotive lamp shape detection method, comprising the following steps of: obtaining the position and the angle ofthe gap value measurement are according to the three-dimensional model of the body contour block; and separately measuring the body contour block and the lamp to be tested according to the above position and angle. When separately measuring the body contour block and the lamp to be tested, the photoelectric sensor for measuring the two-dimensional contour data of the above two can respectively adopt two exposure measurement parameters to adapt to the transparent lamp to be tested and the non-transparent body contour block. Furthermore, the problem that the conventional photoelectric sensor measurement method is difficult to accurately measure the exposure of the lamp and the body contour block at the same time is solved.

Description

technical field [0001] The invention relates to the field of vehicle lamp detection, in particular to a method for detecting the shape of a vehicle lamp. Background technique [0002] Before the existing automobile lamps are installed, the measurement of the gap between the lamps and the body is generally carried out manually. The manual detection method is to install the profiling blocks of the lamps and the body on the inspection tool, and then use the measuring tool to measure the gap between the lamps. and the gap between the profiled block of the body is measured. There are many disadvantages in manual inspection, mainly reflected in the low inspection efficiency, the installation process and measurement of lights, profiling blocks and inspection tools take a long time, and the measurement results are easily affected by human factors. If some photoelectric sensors are considered to detect the gap between the car lamp and the body profiling block, the following problems...
