1. Use visual inspection of products to replace human visual inspection. Including: shape inspection, that is, checking and measuring the geometric size, shape and position of parts; Defect inspection, that is, checking whether the parts are damaged or scratched; Complete inspection, that is, to check whether the parts on the component are complete.
2. Identify the parts to be assembled one by one, determine their spatial position and direction, and guide the robot's hand to accurately grab the required parts and put them in the designated position to complete the classification, handling and assembly tasks.
3. Navigate for the mobile robot, and use the vision system to provide the external information of the environment in which the mobile robot is located, so that the robot can independently plan its travel route, avoid obstacles, reach the destination safely and complete the specified work task.
The first two of them belong to the category of industrial robots, and with the development of technology, researchers have also proposed the concept of visual servo. Visual navigation, whether autonomous, semi-autonomous, or the earliest remote control mode, is an interactive process between the actor (subject) and the environment (object) to complete a certain task.
Despite this, the vision of mobile robots has not yet reached the point where vision is so important to humans compared to humans, and a large part of the reason is that the theory and method of visual information processing are not perfect. The camera can scan millions of pixels of the environment in a very short time, even more than the current human eye information collection capacity, but in terms of processing methods and processing speed is far from comparable to humans.
However, it can be believed that with the progress of microelectronics technology and the development of computer vision, the visual function of mobile robots will become more and more powerful, and at the same time, machine vision will account for an increasing proportion of mobile robot information perception.
