Embodiment Construction

[0033] Reference will now be made in detail to embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings, wherein like numerals refer to like elements throughout.

[0034] figure 1 is a diagram showing the configuration of the gesture recognition device 100 according to the embodiment of the present disclosure. refer to figure 1 , the gesture recognition device 100 may include an image acquisition unit 110 , a modeling unit 120 , a gesture sample generation unit 130 , an image prediction unit 140 , a gesture recognition unit 150 and a storage unit 160 .

[0035] The image acquisition unit 110 includes a main sensor or a depth camera. The image acquiring unit 110 captures an image of a target to acquire a depth image about the target. figure 2 is a diagram showing an example of a depth image obtained by an image acquisition unit in practice. according to figure 2 In the depth image shown in , the bright part indicates that the ...

Abstract

An apparatus and a method for pose recognition, the method for pose recognition including generating a model of a human body in a virtual space, predicting a next pose of the model of the human body based on a state vector having an angle and an angular velocity of each part of the human body as a state variable, predicting a depth image about the predicted pose, and recognizing a pose of a human in a depth image captured in practice, based on a similarity between the predicted depth image and the depth image captured in practice, wherein the next pose is predicted based on the state vector having an angular velocity as a state variable, thereby reducing the number of pose samples to be generated and improving the pose recognition speed.

Description

technical field [0001] Embodiments of the present disclosure relate to a method and device for gesture recognition, and more particularly, to a method and device for gesture recognition capable of improving the recognition speed of gesture recognition. Background technique [0002] In recent years, with the development of non-contact sensors such as depth cameras or accelerometers, the interface between human and machine devices has changed from a contact method to a non-contact method. [0003] The depth camera shines laser light or infrared (IR) light on the target and calculates the distance between the camera and the target (i.e. , the depth information of the target). By using a depth camera, a three-dimensional depth image including depth information of each pixel is obtained. [0004] If the three-dimensional depth image obtained as above is used, the posture information of the person can be measured to a more precise degree than in the case of using only the two-di...
