Paper Abstract

This paper aims to design a multi-line structured light projector with equal spacing, small volume and long-term use. The application background of the projector is the rubber coating detection in the automobile industry, which needs to have the characteristics of high brightness, good monochromaticity, and clear visible projection on the black plastic material. Because the glue is slightly heated, the glue will affect the detection effect. Therefore, it is necessary to ensure sufficient light intensity, and the light is not too strong. Too strong light will cause the glue to be baked and lose the meaning of detection. The projector designed in this paper utilizes a plurality of semi-transparent mirror splitting and wire-cutting processing means to ensure the positional relationship of the light strips. It has the following advantages: simple structure, convenient calibration, small size and low price.
