The visual servo system consists of a visual system, a servo control strategy, and the device itself. The visual system obtains appropriate real-time feedback information by extracting image visual features. The servo control strategy calculates control quantities that meet performance constraints based on visual real-time feedback information and the current status of the machine. The device body receives the output of the servo control strategy and performs corresponding actions.

The use of PVT motion control algorithm can ensure precise control of the position and speed of the target at a specific time point. Even in applications involving high-speed processing of micro holes and large inertia, the following error of the motion platform can reach the micron level, thus satisfying various needs. Occasions that have strict requirements on trajectory in manufacturing engineering, such as precision dispensing, high-speed laser processing, etc.
