Embodiment Construction
[0032] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0033] One of the core concepts of the embodiments of the present invention is to combine binocular stereo vision with two sets of structured light to perform three-dimensional reconstruction of user gestures. After obtaining three-dimensional information, combined with time information of user gestures, four-dimensional information of user gestures is obtained. And calculate the trajectory of the user's gesture based on the four-dimensional information; match the trajectory with the preset trajectory, and if the matching is successful, obtain the corresponding control command to control the smart device.

The invention provides a method and device for conducting gesture control on a smart device. The method comprises the steps that three-dimensional reconstruction is conducted on user gestures by adopting first structured light and second structured light to obtain a three-dimensional information matrix of the user gestures, wherein the first structured light and the second structured light have different coding structures; a four-dimensional information matrix is generated by combining the three-dimensional information matrix with corresponding time information; gesture tracks of the user gestures are obtained on the basis of the four-dimensional information matrix; if the gesture tracks are successfully matched with a preset gesture track category, a control instruction corresponding to the matched preset gesture track category is acquired, wherein the preset gesture track category has the corresponding control instruction; the control instruction is executed on the smart device. Accordingly, the image sequence acquisition time can be shortened, and the compactness, robustness and precision of a three-dimensional information result are improved.
Description
technical field [0001] The invention relates to the field of human-computer interaction, in particular to a method for gesture control of smart devices and a device for gesture control of smart devices. Background technique [0002] With the development of information technology, Human–Computer Interaction (Human–Computer Interaction or Human–Machine Interaction, HCI or HMI for short) technology is gradually becoming popular. As an important branch of human-computer interaction, gesture recognition has been a research hotspot in recent years. [0003] At present, the commonly used gesture recognition algorithm is a model-based recognition algorithm, which uses multiple cameras to reconstruct the gesture in 3D, obtains the 3D information of the gesture, and matches the 3D information with a given 3D model. [0004] In computer vision, 3D reconstruction refers to the process of reconstructing 3D information from single-view or multi-view images. In the process of obtaining 3...
