The invention discloses an
infrared-based three-dimensional (3D)
gesture recognition controller and a realization method. The controller comprises a transmitting unit, a receiving unit, a control
processing unit and an output unit; the transmitting unit consists of an
infrared laser; the receiving unit is used for receiving the
infrared ray which is reflected by a hand on the front end of the controller and converting the infrared
ray into the information to be transmitted to the control
processing unit according to the intensity of the reflected infrared
ray; and the control
processing unit is used for opening and closing the transmitting unit in turn, calculating a distance from each infrared transmitting point to the controller according to the information of the receiving unit, judging a movement gesture of the hand on the front end of the controller according to the distance of each infrared reflection point of each time point to the controller and outputting a
gesture recognition result through the output unit. Due to the adoption of the infrared-based 3D
gesture recognition controller and the realization method, the 3D
action recognition of the gesture can be realized, the result can be outputted, including the gesture of the hand from left to right,
right to left, front to rear, rear to front, top to bottom and bottom to top; and simplicity and feasibility in use can be realized, and the cost is low.
