How Do You Control Light Intensity In Machine Vision? - How It Comes Together

Описание: How Do You Control Light Intensity In Machine Vision? In this informative video, we will discuss the essential role of light intensity control in machine vision systems. Understanding how to manage light intensity is key for achieving clear and consistent images during inspections in manufacturing automation and robotics. We will explore the two primary methods of controlling light intensity: analog control and digital control.

Analog control involves adjusting the brightness of light sources, such as LEDs, through voltage changes. While this method can provide linear brightness adjustments, it has its limitations, particularly regarding heat generation and the need for precise voltage tuning. On the other hand, digital control, especially through Pulse Width Modulation (PWM), offers an efficient way to manage brightness without the drawbacks of heat buildup, making it a preferred choice in many applications.

We will also cover the importance of synchronizing light intensity with camera exposure times, as well as the various illumination techniques that enhance image quality. By mastering these techniques, manufacturers can significantly improve the accuracy and reliability of their automated inspection processes.
