Machine vision detection system has become an indispensable part of industrial production. In terms of the amount of information collected and interpreted in the production process, machine vision is the most abundant, and it is the key technology to successfully realize industry 4.0.
For intelligent robots, robot vision detection system is the core technology of environment perception, including 2D vision system and 3D vision; at present, 2D vision system technology is relatively mature, and 3D vision system is relatively limited.
The control of intelligent robot must first do environment perception, make control decision according to the environment and task, and finally execute the corresponding action. The requirement of robot vision here is that first of all, you must understand the environment, including the perception and understanding of the environment, and then you may have to perform tasks to be able to find the target.
Robot vision system must meet the requirements of real-time. For industrial robots, the decisive factors to realize the automation include the combination of software and hardware; among them, the main factor of hardware lies in the hardware part of machine vision acquisition, including industrial camera / industrial intelligent camera, lens, light source, etc., but the most difficult technology to determine its motion trajectory and action is software, because software needs to solve the problem of thinking.
At present, robot vision system mainly includes general-purpose type and embedded type, which is more commonly used because it can meet complex engineering applications, its performance can be configured higher, and it is easy to maintain.
At present, the application of embedded system is less. Although it saves space and looks beautiful, it has too many limitations. With the continuous development of technology, embedded system will become the mainstream.
At present, the mainstream domestic industrial robot vision system is fully compatible with different types of manipulators and PLC control systems, mainly to solve the problems of dynamic position tracking and positioning, precise positioning and admire, precise position adjustment, etc.
