Machine vision integrates various technologies, i.e., optics, machinery, electronics, computer software and hardware, to enable the extraction of different image features that are critical in different vision tasks. Therefore, image quality determines the success or failure of the entire Machine Vision system. To achieve high quality image, high-quality lighting is essential. Depending on the imaging configurations and targets, proper lighting components and solutions should be designed. Machine Vision Lights controller: analog controller, digital controller, strobe controller, diffusion board for constant current controller (optional). The Lights are located above the measured object and shines on the surface of the measured object. According to the luminous angle, OdinVision Lights can be divided into high-angle Lights, low-angle Lights, as well as high and low angle shadowless Lights. High-angle Light Definition: If the angle between the light and the horizontal plane is bigger than 45°, it is called high-angle light. Effect analysis: for the high-angle light, lights reflected from the even part of the target surface can enter into the lens, and as suh the resulting image has high grayscale values. But, lights reflected from uneven part of the surface cannot enter into the lens, and as such the resulting image has low grayscale values. Main applications: positioning, character detection, contour detection, scratch detection, dimensional measurement. Common Lights: high-angle ring light, strip light, surface light, coaxial light, point light, etc. Low-angle Light Definition: If the angle between the light and the horizontal plane is smaller than 45°
