Embodiment 1

[0034] figure 1 It is a flowchart of the gesture recognition method described in this embodiment. Such as figure 1 As shown, the gesture recognition method described in this embodiment includes:

[0035] S101. Acquire three-dimensional data of an identification object.

[0036] In a preferred implementation of this embodiment, the identification object may be a human hand.

[0037] In a preferred implementation of this embodiment, the three-dimensional data acquisition method may be: adopt an existing three-dimensional space data acquisition method, and acquire it through an identifier. For example, binocular disparity can be used to calculate the three-dimensional information. For another example, a TOF (Time of Flight, time of flight) method may be used to calculate the depth map by calculating the reflection time of light to obtain the three-dimensional data of the identified object. For another example, the monocular structured light method can be used to calculate th...

Embodiment 2

[0078] According to the same idea of ​​the present invention, the present invention also provides a gesture recognition device, image 3 is a schematic structural diagram of the gesture recognition device described in this embodiment, as image 3 As shown, the gesture recognition device described in this embodiment includes a three-dimensional data acquisition module 31 , an operation plane acquisition module 32 , an foot point cloud extraction module 33 , a separation module 34 , a gesture determination module 35 and a gesture execution module 36 .

[0079] Wherein, the three-dimensional data acquiring module 31 is used for acquiring the three-dimensional data of the identification object.

[0080] In a preferred implementation of this embodiment, the three-dimensional data acquisition method may be: adopt an existing three-dimensional space data acquisition method, and acquire it through an identifier. For example, binocular disparity can be used to calculate the three-dime...

Abstract

The invention discloses a gesture identification method and a gesture identification device. The gesture identification method comprises the following steps: acquiring three-dimensional data of a to-be-identified object; fitting the three-dimensional data, and acquiring a fitting operation plane; acquiring foot point cloud of the three-dimensional data on the fitting operation plane; taking a window with preset size by taking each foot point in the foot point cloud as a locating basis; scanning an inner area of the selected window; marking foot points to be separated according to a scanning result; after all the foot points to be separated are removed, classifying communicated areas in the residual foot point cloud into a same independent area; respectively calculating the area of each independent area, so as to acquire the amount of effective areas; when the amount of the effective areas satisfies preset amount conditions, judging that a preset gesture is captured; and executing a command corresponding to the preset gesture. The invention also provides a device that the gesture and the command correspond in consistence. With the adoption of the gesture identification method and the gesture identification device provided by the invention, a gesture of an operator can be rapidly and accurately captured, and the command corresponding to the preset gesture is executed.

Description

technical field [0001] The present invention relates to the field of human-computer interaction technology, in particular to a gesture recognition method and device. Background technique [0002] At present, the operation of files is limited to the mouse and keyboard. This operation method is extremely inconvenient in some cases. For example, in a demonstration occasion, the speaker may need to operate multiple files, and may need to minimize the current program and open the next one. file and maximize the file to highlight it. Although the current mouse operation can easily click the maximum and minimum buttons, it requires the operator to rely on the mouse and keyboard during operation, and cannot comfortably perform human-computer interaction at any position. [0003] At present, as a new interaction method between humans and computers, somatosensory operation recognition technology is widely used in various fields such as intelligent robots, computers, game consoles, mo...
