3D vision is a breakthrough in machine vision
The emergence of 3D vision has driven the rapid innovation of industrial robots and broadened their UV application prospects. New vision technologies give robotic systems the flexibility to perform functions that they have never had before.
Industrial robots themselves are incredible innovations in manufacturing, but the "blind" version of robots has its limitations. So what is the difference between a 3D vision guided robot and a traditional robot?
Robots are used in large numbers to replace boring, repetitive work, and liberate the low-end labor force. But because of the lack of visual awareness that limits their ability to perform more high-end tasks, traditional robots must be programmed to accomplish a single task without the ability to cope with new changes, and must be reprogrammed when the task changes.
Flexibility is a key driver of ROI's return on investment. 3D vision capabilities enable robots to perform multiple tasks without reprogramming, while predicting unforeseen surprises in the work environment. In addition, 3D vision allows the robot to recognize the object in front of it to a certain extent and respond accordingly. All of these features increase the flexibility of the robot for faster and better return on investment.
At present, 3D vision technology has many methods in industrial robot applications. One of the most prominent application methods is picking and placing, which is very difficult for traditional robots. Blind robots can only pick objects from predetermined positions, 2D cameras. The system was unable to pick a part from the scene.
The three-dimensional vision realized by laser triangulation is one of the most commonly used methods of robot vision in picking and positioning applications. Essentially, a computer-aided design (CAD) model is taught to the robot to identify a part of the space and its direction. The laser is used by the robot to determine its spatial position on the X, Y, and Z axes. Once the robot knows where it is and the part, it can pick up the part and place it.
Although this seems like a simple task, it is a revolution in the industrial field. It saves time and money for end users. With the simple description of the CAD model, the robot can perform a variety of tasks.
Whether it's from laser triangulation or a different approach, 3D vision is the driving force for innovation. The selection and use of robots in the past was very difficult, but now it will be a normal operation.
