Embodiment 1

[0046] A method for realizing a human motion recognition training system, comprising the following steps:

[0047] (1) Collection of training information:

[0048] The various action samples that need to be recognized are collected through the depth detection camera and the third-party SDK, and when the collected sample data is stored, the storage format includes the following fields: Action ID (Action ID: Int32), Action Name (Action Name: String), logarithm of motion information frame (Frame Count: Integer), depth information frame (Depth Frame #n: Integer Array) and bone information frame (Skeleton Frame #n: Integer Array);

[0049] (2) Regularization processing of sample data:

[0050]a. Unify the coordinate system, that is, perform coordinate transformation on the depth information data and bone information data of each frame, and unify them into the same world coordinate system;

[0051] b. Discretize the coordinates of bone points, that is, discretize the coordinates o...

Abstract

The invention discloses an achieving method of a human movement recognition training system. The method includes the following steps of (1) collecting training information, (2) normalizing sample data, (3) extracting a characteristic three-dimensional vector set, and (4) recognizing and identifying motions. According to the method, a reduced precision discretization coordinate algorithm is used for simplifying operation information representation and reducing calculation amount of a characteristic extraction algorithm, and meanwhile a multi-level feature matching algorithm is used for accelerating the recognition speed. The achieving method is simple and reasonable in logical design and algorithm, feasible, reliable and easy to achieve.

Description

technical field [0001] The invention belongs to the technical field of computer engineering, and relates to a method for realizing a training system based on machine learning for generating a specific human action recognizer. Background technique [0002] Action recognition is a very popular research field in recent years. Through image capture equipment, the recognition process of human body actions can be completed in a short period of time, and converted into operating instructions for computers and other equipment; thus it is used as an effective input method. Applied to a wide range of applications such as games and movie production. [0003] The first problem to be solved in action recognition is to find the part of the human body. The part of the human body is the basis for action recognition, which is generally called "focus position". Because usually the attention position is exposed parts such as human face and hands, and its color is quite different from the envi...
