The invention provides an automatic swimming timing method and system based on a visual technology and a medium, and relates to the technical field of swimming timing. The method comprises the steps that four AI detection cameras are arranged on the two side faces of the two ends of a swimming pool respectively and used for detecting a target frame and a body closing point node of a human body appearing in a picture through a trained YOLO model; performing picture calibration on the first to fourth AI detection cameras, and calibrating a touch wall line and a lane separation line; the processing unit judges whether all personnel are in place according to the detection result of the AI detection camera and the wall contact line; uniformly calculating the starting time of each lane when the starting sound is played and the targets are in place according to regulations; and then the processing unit judges wall contact according to the detection result of the AI detection camera in combination with the wall conta
