Embodiment Construction

[0052] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0053] Such as figure 1 As shown, the first aspect of the present invention relates to a real-time human motion recognition method S100, the method S100 comprising:

[0054] S110. Acquire a depth image of the human body to be identified in real time.

[0055] Specifically, in this step, a 3D camera may be used to collect a depth image of the human body to be recognized in real time. Of course, in addition to the 3D camera, other image acquisition devices that can acquire the depth image of the human body in real time can also be used.

[0056] It should be noted that, in this step, the human body to be identified may only include one person, and of course, th...

Abstract

The invention discloses a real-time human body action recognition method and a real-time human body action recognition device. The method comprises the following steps of acquiring a depth image of ato-be-recognized human body in real time; extracting the skeleton data of the human body in the depth image according to the depth image, and performing normalization treatment on the skeleton data, wherein the skeleton data comprises a joint point data set of human body key nodes; acquiring an action recording file, wherein the action recording file comprises a preset action recording file; setting a joint point combination according to the action recording file, and marking the starting position of actions in the action recording file; training the actions in the action recording file by utilizing a preset algorithm, extracting a feature vector and storing the feature vector into an action template file; recognizing the action of the to-be-recognized human body based on the action template file and the joint point data set, and outputting a recognition result. The human body action recognition accuracy can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of human motion recognition, in particular to a real-time human motion recognition method and a real-time human motion recognition device. Background technique [0002] The history of human-computer interaction technology has been developed for more than 50 years. In recent years, the use of motion recognition technology to realize human-computer interaction has become one of the key research directions of scholars at home and abroad. Human action recognition is a challenging topic in computer vision, but it also has broad application prospects. Vision-based human motion analysis is a very active research direction in the field of computer vision, which includes motion detection, object classification and tracking, and understanding and recognition of human motion. The relationship between these contents is progressive: the detection of moving human body is the basis of target classification and tracking, a...
