Embodiment
[0052] Such as figure 1 As shown, the gesture control system of the present invention includes two color cameras with clock synchronization, a processor and two three-dimensional projectors.
[0053] Wherein, the color camera 103 is used to capture the forward and backward movement of the operator's gesture 101; the color camera 102 is used to capture the left and right movement of the operator's gesture;
[0054] The processor is used to analyze the image sequence captured by the gesture capture sensor, obtain the position information of the gesture in each frame of the image sequence and the speed information of the current gesture movement, and divide the interface to be projected into left and right according to the obtained operation information. projection area and right projection area;
[0055] The three-dimensional projectors 105 and 106 are placed opposite to the left and right fronts of the color cameras 102-103; they are respectively used to receive the data of th...

The invention discloses a gesture control system comprising two gesture capturing sensors with clock synchronization, a processor and two three-dimensional projectors, wherein one of the gesture capturing sensors is used for capturing the front-back movement of the gesture of an operator and the other one is used for capturing the front-back movement and the left-right movement of the gesture of the operator; the processor is used for analyzing the image sequence captured by the gesture capturing sensors, obtaining the location information of the gesture in each frame of image of the image sequence and the velocity information of the current gesture movement and dividing the interface needed to be projected into a left projection area and a right projection area according to the obtained operating information; and the two three-dimensional projectors are oppositely arranged in the left front and the right front of the gesture capturing sensors and respectively used for receiving data of the left projection area and the right projection area and projecting. The invention also discloses a control method of the system. Compared with the prior art, the gesture control system disclosed by the invention is simpler and more convenient for operation, simple and natural in gesture and low in error recognition rate.
Description
technical field [0001] The invention relates to the field of human-computer interaction control, in particular to a gesture control system and a control method thereof. Background technique [0002] In the non-contact human-computer interaction system, the human-computer interaction based on gesture control is an important link. Human-computer interaction based on gesture control is simple and convenient, and its commonly used operation method is gesture roaming. Gesture roaming refers to mapping the movement of gestures in physical space to the interface of the controlled object to realize the operation of the controlled object. The existing gesture motion mapping method is mainly two-dimensional motion, such as using the mouse to draw a trajectory on the screen to operate the application. This method is different from the habit of human beings moving in three-dimensional space, and the intuitive experience of human-computer interaction is low. . Even if some new 3D oper...
