Problems solved by technology

The current mainstream detection method is to detect the human body in the image, and then detect key points in the detected human body. The process is complicated, the calculation is large, and extremely high hardware conditions are required: in terms of GPU, most of them use multiple graphics cards , the model of each graphics card is no less than NVIDIA Tesla K80; in terms of CPU, most of them use Core TM i5, it is very difficult to achieve widespread application in daily life under such conditions, which will affect its popularization and use

[0028] Please refer to figure 2 , figure 2 It is a flowchart of a method for detecting a two-dimensional posture according to a preferred embodiment of the present invention. The two-dimensional posture detection method includes the following steps:

[0029] Step S101: Acquire a frame of RGB image data including a human body at a preset time interval.

[0030] In this embodiment, the RGB image data may be RGB image data sent by a terminal communicatively connected with the server 100 received through the communication unit 113. The terminal may be an image acquisition device (for example, a camera, a mobile phone), or an electronic device that can store images. In this embodiment, the terminal is a camera, and the server 100 obtains one frame of real-time RGB image data from the camera at a preset time interval.

[0031] Step S102: Perform normalization processing on the RGB image data to generate the two-dimensional human body image data.

[0032] In this embodiment, the average ...

Abstract

The invention provides a two-dimensional gesture detection method and device, and relates to the field of computer vision. The two-dimensional gesture detection method comprises the following steps that: obtaining a plurality of key points and the position information of each key point from two-dimensional human body image data; according to a preset rule, mapping a plurality of key points to a pre-created feature map; evaluating close connection between any two key points mapped to the feature map; and connecting the two key points which exhibit the close connection to generate a gesture skeleton line to detect the gesture of a human body. The gesture skeleton line can be accurately and quickly generated without depending on the depth information of an image, requirements on hardware equipment are lowered, processing speed is high, and the accuracy of a detection result is high.

Description

Technical field [0001] The invention relates to the field of computer vision, and in particular to a two-dimensional posture detection method and device. Background technique [0002] Human posture detection has broad application prospects in the fields of fitness, security detection, medical treatment, and national defense. The research on human posture detection technology is one of today's hot topics. [0003] The posture skeleton line can be used to recognize the human posture. The result of human posture detection using posture skeleton line is more accurate, and it is not easy to reveal privacy. [0004] But even after so many years of development, human posture detection is still a difficult problem in computer vision. The current mainstream detection method is to detect the human body in the image, and then detect the key points in the detected human body. The process is complicated, the calculation is large, and it requires extremely high hardware conditions: in terms of G...
