Abstract

The invention discloses a gesture recognition method and system based on depth information, and the method comprises the steps: training a CNN model responded by a human body part, inputting an imageread by a camera, obtaining a response graph of an upper body part of a human body through the prediction of the trained model, judging the position of a hand, and segmenting a hand position image; training a CNN model based on hand joint points to realize end-to-end joint point positioning; preprocessing the segmented hand position picture, inputting the segmented hand position picture into a model for joint point position prediction, and fitting to form a gesture; clculating the distance between the position of the finger joint point and the central position of the palm, and judging the gesture matched with the position relation. According to the gesture recognition method and system based on the depth information provided by the invention, the depth information can be read in a complexscene, and interaction with the display is carried out through gesture recognition.

Description

technical field [0001] The invention belongs to the technical field of image processing and intelligent interaction, and relates to a gesture recognition method and system based on depth information. Background technique [0002] With the development of science and technology, more and more scholars pay attention to the research and application of human-computer interaction. Among them, gesture recognition, as a main branch of human-computer interaction, is one of the important research topics in the field of human-computer interaction. Gesture interaction has the advantages of convenience, strong interactivity, and rich expression content for users, and has always been the first choice of human-computer interaction. [0003] Before the popularity of depth cameras, gesture recognition mostly used two-dimensional RGB image input, which was easily disturbed by complex backgrounds, and the accuracy could not achieve the ideal interaction effect. [0004] In view of this, ther...
