Machine vision is essential for the application of robots. Both industrial robots and service robots need robot vision as their "eyes." However, there are differences between the robot vision used in industrial robots and service robots. Let's take a look at the specific differences.
The primary difference between machine vision in industrial robots and service robots lies in their application scenarios. In the environment of industrial robots, computer vision perceives a relatively singular scene, such as industrial components or materials, or monitoring certain operational processes. Service robots, on the other hand, have much more diverse application scenarios, including everyday life scenarios, such as recognizing jewelry or facial expressions. Within service robots, such as home robots and drones, vision is a crucial navigation tool, used to measure and model the surrounding environment. Another typical application is surveillance.
The second difference between the application of robot vision in industrial robots and service robots lies in accuracy. In industrial robots, the recognition accuracy of computer vision is always below the millimeter level, including both static and dynamic recognition accuracy. Static recognition refers to a situation where the camera or the observed object is relatively stationary. In this case, the recognition accuracy depends on the camera resolution, including whether the edges of the object are clear and whether the differences are distinct. At this level, the accuracy can even reach below the micrometer level. Service robots, on the other hand, generally do not have very high accuracy, which may be above the centimeter level.
This shows that the application of machine vision differs among different types of robots. Industrial robots perform tasks that require high precision, while service robots do not. Therefore, there is a significant difference in precision between the two. Furthermore, service robots primarily serve people and require more spatial and scene recognition, while industrial robots only need to recognize the working environment and people.
