Measurements

What is measurement in machine vision ?

In machine vision, Measurement refers to the process of using advanced imaging techniques to capture and analyze an object’s physical characteristics, such as dimensions, shape, position, and surface quality. This is achieved through high-resolution cameras, sensors, and software algorithms that enable precise measurements, often with sub-millimeter accuracy. Techniques like edge detection, pattern recognition, and 3D imaging are commonly used to measure various attributes, making machine vision a valuable tool for quality control, automated inspection, and assembly processes in industries like manufacturing, robotics, and logistics.

Essential Components of Machine Vision Measurement Systems
