Problems solved by technology

However, due to the uncertainty of vision, it has the disadvantages of relying on the viewing angle of camera observation, poor adaptability to background and environment changes, etc.
[0004] To sum up, the current smart home and industrial control still lack simple, low-cost, non-contact gesture interaction devices.

Embodiment Construction

[0027] In order to make the purpose, technical solutions and advantages of the present invention clearer, the implementation of the present invention will be further described in detail below in conjunction with the accompanying drawings:

[0028] This embodiment provides an infrared-based 3D gesture recognition controller structure, see figure 1 , the controller 1 includes: a transmitting unit 2, a receiving unit 3, a control processing unit 4 and an output unit 5;

[0029] The emitting unit is composed of an infrared exciter 6;

[0030] The receiving unit is used to receive the infrared light reflected by the hand at the front of the controller, and convert it into information according to the intensity of the reflected infrared light and send it to the control processing unit;

[0031] The control processing unit is used to open and close the transmitting unit in turn, and convert the distance from each infrared reflection point to the controller according to the informati...

Abstract

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.

Description

technical field [0001] The invention relates to an infrared-based 3D gesture recognition controller and a realization method, in particular to a gesture recognition controller and a realization method for smart home and industrial control. Background technique [0002] Smart home is the development trend of future home furnishing. Its human-computer interaction interface will develop from the existing graphical interface (mainly used in the window of the screen and the operation mode of keyboard and mouse) to the physical user interface. Gesture recognition technology will be used in smart home. A large number of applications in the home; contact gesture recognition is not affected by changes in the external environment and background, the amount of calculation is small, and it has better real-time performance, but there are disadvantages such as inconvenient use and high cost. The non-contact gesture recognition technology better solves the compatibility problem of use and ...
