The present invention discloses an artificial muscle collaborative mirror rehabilitation system and control method based on ultrasonic detection control. The rehabilitation system includes an ultrasonic detection group, a pneumatic muscle group, and an electric control group. The ultrasonic detection group performs high-density array ultrasonic detection on the muscles of the user's healthy limb to obtain the muscle state of the healthy limb, and analyzes the muscle state information through the electric control group to resolve the limb collaborative movement information. The pneumatic muscle group simulates the layout and attachment method of human limb skeletal muscles on the bones, and is controlled by the electric control group for collaborative drive to achieve mirror movement of the healthy limb. The present invention adopts ultrasonic detection and pneumatic muscle simulation of mirror movement, which can detect the movement pattern of the healthy limb (including movement amplitude, movement angle, movement speed and strength, etc.) at the muscle level, and collaboratively control the affected limb in real time to completely imitate the movement of the healthy limb, so that the rehabilitation equipment can assist the patient to achieve the mirror movement effect and improve the rehabilitation efficiency.

Different illumination lines, generated by a first and a second laser separated by a selectable angle between 1 and 15 degrees, are swept across a field of view using a scanning mirror. This is done in such a way that an object is illuminated successively with a known time delay, determined by the angular separation and the mirror movement. Reflections from the object are detected by corresponding detectors, and the data from these events is processed to generate position information for each illumination. By analyzing the change in the object's position between the captured data points and incorporating a controlled time delay, a velocity measurement of the object is calculated.
