Embodiment Construction
[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0028] In the embodiment of the present invention, by irradiating the light source on the body with the through hole, since the reflection intensity of the through hole and the body are different, according to the principle of optical imaging, the collected image of the body with the through hole includes the edge of the body and the through hole. The black and white image of the hole, by measuring the distance from the center of the through hole to the edge of the body in the black and white image, can detect whether the distance between the through hole and the edge of the body in the body with th...

The present invention is applicable to the field of distance detection, and provides a method and system for detecting the position of a through hole. The method includes the following steps: collecting an image of a body with a through hole illuminated by a light source, and the image includes the edge of the body and A black and white image of a via; detect the distance of the edge of the body from the via in said image. In the embodiment of the present invention, by irradiating the light source on the body, according to the principle of optical imaging, a black and white image including the edge of the body and the through hole can be collected, and by detecting the distance between the through hole and the edge of the body in the black and white image, it can be more objective , More accurately detect whether the position of the through hole in the body meets the requirements. At the same time, due to the use of software to control the detection method of hardware, batch detection can be realized, which greatly saves time and human resources, reduces labor intensity, and ensures the quality of detection.
Description
technical field [0001] The invention belongs to the detection field, in particular to a method and system for detecting the position of a through hole. Background technique [0002] The bodies of many existing products are provided with through holes for fixing. For example, the inner surface of the mobile terminal shell is also inlaid with threaded holes for fixing the camera or the main board of the mobile terminal. Due to the small size of the threaded hole, it is difficult to process. When the threaded hole is embedded in the inner surface of the mobile terminal shell, there will inevitably be errors. The distances are inconsistent. If the error is large, it will reduce the quality of the finished product of the mobile terminal, thereby affecting the reputation and development of the enterprise. Therefore, it is necessary to detect the distance between the threaded hole embedded in the casing of the mobile terminal and the edge of the mobile terminal. [0003] In the ...
