What is Machine Vision?
Machine vision is machines' vision, which gives machines visual perception so that machines have scene perception capabilities similar to biological vision systems.
Vision is our most powerful way of perception. We can obtain much information about the surrounding environment through visual perception without contact. After the advent of computers, people began to try to imbue machines with visual perception capabilities.
Because biological vision systems are very complex, we cannot fully equip a machine with this powerful visual perception capability. We are still committed to building a machine vision system that handles specific tasks in a controlled environment. Since the visual environment in industry is controllable and the processing tasks are specific, most machine vision is now used in industry.
What is the main task of machine vision?
The main task of machine vision is to generate a set of description information for the scenes or objects involved in the image by analyzing the image.
That is to say, the input of the machine vision system is an image (or image sequence), and the output is a perceptual description of these images. This set of descriptions is closely related to the objects or scenes in these images, and these descriptions can help the machine complete specific subsequent tasks and guide the robot system to interact with the surrounding environment.
For example: instruct the robot arm to grab parts on the conveyor belt as required. The type, position and orientation of the parts are arbitrary. When the parts on the conveyor belt pass by the camera above, a set of descriptions can be generated through machine vision: type, position, and orientation, thereby guiding the robot arm to grab as required.
