Embodiment Construction

[0026] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

[0027] Such as figure 1 As shown, the specific embodiment of the present invention is: the technical solution of the present invention is: provide a kind of gesture input method construction method based on computer vision, the steps are as follows

[0028] Step 100: Collect gestures, that is, capture gesture video signals to obtain gesture data image frames.

[0029] The specific implementation process is as follows: a gesture word is a limited basic gesture sequence, and each basic gesture includes the following three stages: the preparation stage, that is, the movement stage of moving the hand from an initial rest position to the key gesture position; the key gesture stage, That is, the gesture action stage; the recovery stage, that is, the movement stage in which the hand returns to the initial position. In a specific embodiment of the prese...

Abstract

The invention relates to a computer-vision-based gesture input method construction method, which comprises the following steps of: gesture acquisition, video processing, gesture analysis, gesture identification and construction of a gesture input method. Gesture frames are clustered by utilizing an asynchronous buffering model to obtain key gesture frames, and only the key gesture frames are subjected to the subsequent gesture analysis and gesture identification; therefore, compared with the conventional system for analyzing and identifying each frame of gestures, a system provided by the invention can give a more real-time response. In addition, the combined application of the gesture identification and the input method is creative in the history of human-computer interaction.

Description

technical field [0001] The invention relates to a gesture input method construction method and system, in particular to a gesture input method construction method and system based on video clustering processing. Background technique [0002] With the development of technology, gesture input technology has also been greatly developed in some special fields. The premise of gesture input technology is to collect gesture signals, and then analyze and process the collected gesture signals. The detection of the gesture target refers to the detection of the gesture target from the image stream under the complex background conditions of people, and then the gesture recognition. Gesture recognition is to interpret its high-level meaning based on the gesture and change process of the human hand. Since the gesture has the following four characteristics, extracting features with geometric invariance is one of the main key technologies for the realization of the gesture input method: the...
