Problems solved by technology

[0003] At present, the algorithm used in the recognition process of the existing gesture recognition technology is relatively complicated, which is not only time-consuming, but also has low precision and poor accuracy in recognizing gestures.
In addition, the existing gesture recognition technology based on pattern recognition has poor real-time performance and is not suitable for occasions requiring instant interaction.

Abstract

The invention provides a gesture identification method including that a detected image sequence including depth information of the hands of a user is acquired; based on the image depth information and image color information, the hand contour of the user can be detected from every frame of the detected image sequence; for each hand of the user, the detected characteristic point sequence of the hand is determined in the every frame of the detected image sequence by means of a preset hand structure template; for each hand of the user, the matching sequence of the detected characteristic point sequence of the hand is determined in a plurality of preset characteristic point sequences, and the motion names and positions of the hand are determined based on the matching sequence; and gestures matched with the motion names and positions of the hands of the user are selected from a preset gesture table to be the gesture identification result of the detected image sequence. The gesture identification method can accurately identify the gestures of users, and is high in identification precision and fast in identification speed.

Description

technical field [0001] The invention relates to signal processing technology, in particular to a gesture recognition method. Background technique [0002] With the development of science and technology, electronic devices such as notebook computers, mobile phones, and tablet computers gradually have more and more functions, and gesture recognition is just one of these functions. [0003] At present, the algorithms used in the recognition process of the existing gesture recognition technology are relatively complicated, which not only consumes time, but also has low precision and poor accuracy in recognizing gestures. In addition, the existing gesture recognition technology based on pattern recognition has poor real-time performance and is not suitable for occasions requiring instant interaction. Contents of the invention [0004] A brief overview of the invention is given below in order to provide a basic understanding of some aspects of the invention. It should be under...
