The application provides a ROS-based distributed mobile robot visual servo following method, comprising: constructing a distributed heterogeneous control architecture separating an upper computer from a lower computer; the upper computer detects a target through a YOLO model and locks the target to follow, calculates a longitudinal following linear velocity according to a target image feature, encapsulates a linear velocity, a target transverse position, a control parameter and an enable flag bit into a control instruction, and sends the control instruction to the lower computer through a UDP protocol; the lower computer listens to and analyzes the UDP instruction through a ROS node, executes a transverse PD steering control to calculate an angular velocity, combines the longitudinal linear velocity to generate a motion instruction, drives a chassis to execute a following action, and triggers a safety shutdown when the target is lost or communication is abnormal. The application solves the problems of control delay caused by insufficient computing power of an existing single-board computer full-stack scheme, poor robustness in a complex environment and insufficient safety, and realizes high real-time and high-robustness mobile robot visual servo following.
