Intelligent wheelchair human body following control system based on surface electromyogram signals

The invention discloses an intelligent wheelchair human body following control system based on surface electromyographic signals. The system comprises a target detection module, an electromyographic decoding module, a motion control module and an environment monitoring module. The target detection module identifies a target human body and calculates the position of the target human body; the electromyographic decoding module collects electromyographic signals and recognizes the current gesture of an operator according to the electromyographic signals; the gesture is used for specifying expected distance and orientation of the wheelchair following a human body; the motion control module drives the wheelchair to follow the target human body according to the expected relative distance and orientation; the environment monitoring module detects position information of obstacles around the wheelchair to give a safety prompt to an operator, and the wheelchair is braked through the movement module in an emergency.
