Problems solved by technology
[0002] In the field of optical material processing, it is often necessary to measure the profile of transparent materials, such as glass, to obtain information such as its cross-sectional size and volume. Conventional manual measurement methods are inefficient and can only measure a single dimensional parameter.
Optical measurement methods have the characteristics of high efficiency and easy computer automation, and have been widely used in the contour detection of non-transparent materials. However, due to the transmission of light by transparent materials, it is difficult to detect the contour of transparent materials using conventional methods.

The invention relates to a transparent body three-dimensional profile detection system based on line structured light refraction imaging. The transparent body three-dimensional profile detection system comprises an imaging device and an image controller connected with the imaging device. One side of the imaging device is vertically and fixedly provided with a light source generating device, a light receiving plate is arranged under the light source generating device, and the optical axis of the imaging device form an inclined angle to the optical axis of the light source generating device; light emitted by the light source generating device first penetrates through a transparent material to be detected on the light receiving plate and forms light spots on the light receiving plate, then the light spots enter the imaging device for imagining after being refracted by the transparent material, the imaging device sends an imaged image to the image controller, and the image control processes the received image and then calculates the thickness of the transparent material according to the deflection of image points. According to the transparent body three-dimensional profile detection system based on line structured light refraction imaging, by penetrating a transparent body through line structured laser, the shortcomings in the prior art can be overcome; by means of position offset of a virtual image formed through refraction, the profile detection of the transparent body can be achieved and meanwhile good detection results can be obtained.
