Machine vision and sensor technology use camera calibration and 3D reconstruction algorithms to accurately measure objects in images, and use image recognition algorithms for object recognition. Machine vision has shifted from academic research to the commercial field, and is the core of the industrial automation revolution. It does not only focus on the revolution of industrial robot technology. Its applications cover almost all machines and all aspects of the manufacturing cycle. In a wide range of applications such as industrial automation, robotics, drones and 3D modeling, medical instruments, it can provide more detailed and accurate positioning, analysis and measurement of objects. Vision sensor is a key element in any machine vision system, and it is rapidly improving in terms of speed and accuracy.
