Embodiment Construction

[0016] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] like figure 1 As shown, firstly, the camera is used to obtain the lip video image of the target person, and then the lip image is automatically analyzed by the on-site computer to extract the feature value of the lip shape; then the on-site computer uploads the extracted lip shape feature value to the cloud server, The lip shape feature value is matched with the lip shape model in the lip shape model library by the cloud server. In the lip shape model library, each lip shape corresponds to a corresponding text. After the cloud server finds the matching lip model, it feeds back the text corresponding to the matching lip model to the on-site computer, and the on-site computer completes the input of the text.

[0018] As a further optimization of th...

Abstract

The invention provides a lip image recognition character inputting method based on a cloud lip model library under the current condition that language communication among people is difficult in noisy environments such as production workshops and the like. A basic principle of the method is as follows: target person lip images shot by a camera are analyzed automatically by an on-site computer, and feature values of lips are extracted; the extracted feature values of the lips are uploaded to the cloud through a network, the received feature values are matched with lip models in the cloud lip model library by a cloud server, characters corresponding to the matched lip models are fed back to the on-site computer after the matched lip models are obtained, and the characters are input. An effective solution is provided for passing of on-site oral production instructions in the production workshops, and the working pressure of the on-site computer for matching of the lip models is reduced.

Description

technical field [0001] The invention relates to the technical field of human-computer interaction, in particular to a lip shape image recognition text input method based on a cloud lip shape model library. Background technique [0002] In many production workshops, there is a lot of noise in the production environment, which seriously hinders the issuance of oral production instructions on site. [0003] In order to solve the above problems, the present invention provides a lip shape image recognition text input method based on a cloud lip shape model library, which is used to improve the efficiency of issuing oral production instructions on the production site and reduce the working pressure of lip shape model matching on the on-site computer. Contents of the invention [0004] In view of the above problems, the present invention provides a lip shape model based on the cloud lip model library by collecting lip video images and using video processing technology to automati...
