Description

Technical Field

[0001] This utility model relates to the field of visual inspection technology, and in particular to an adjustable multi-angle light source calibration device based on visual inspection. Background Technology

[0002] Visual inspection uses machines to replace human eyes for measurement and judgment. It involves using machine vision products (image acquisition devices, either CMOS or CCD) to convert the captured target into an image signal, which is then transmitted to a dedicated image processing system. Based on pixel distribution and information such as brightness and color, this signal is converted into a digital signal. The image system performs various calculations on these signals to extract the target's features, and then controls the on-site equipment based on the judgment results. It is a valuable mechanism for production, assembly, or packaging. It has immeasurable value in detecting defects and preventing defective products from being delivered to consumers. In machine vision systems, obtaining a high-quality, processable image is crucial. The success of a system depends first and foremost on ensuring good image quality and clear features. Most machine vision projects fail due to poor image quality and unclear features. To ensure a good image, a suitable light source needs to be selected.

[0003] In practical use, most existing adjustable multi-angle light source calibration devices based on vision inspection are manually adjusted, which is slow and does not improve the efficiency of light source calibration and adjustment, or ensure the accuracy and consistency of lighting conditions.
