The invention discloses an augmented reality three-dimensional interactive learning system and a control method, which belong to the technical field of three-dimensional interactive learning systems.A three-dimensional graph can be directly acquired. The system comprises an information processing module, a display, a physical teaching aid, a controller, a horizontal platform, a bracket, a lower flat plate, a middle flat plate and an upper flat plate. The bracket is vertically fixed on the upper surface of the horizontal platform. The lower flat plate, the middle flat plate and the upper flatplate are arranged from bottom to top and are vertically connected with a vertical frame with spacing. A number of vertical sliding holes are uniformly distributed in the lower flat plate. A sliding rod is vertically slidably arranged in each vertical sliding hole. A vertical through hole directly facing each vertical sliding hole is arranged in the middle flat plate directly above the vertical sliding hole. A vertical clamping hole is arranged in the middle flat plate on one side of each vertical through hole. A vertical pipe is fixed in each vertical clamping hole, wherein the lower nozzle of the vertical pipe is sealed. A limit block is fixedly arranged on the lower end in each vertical pipe. A lower fixed pulley and a water pressure sensor are arranged in each vertical pipe below eachlimit block.
