Abstract
The invention provides a text input method based on lip shape image recognition. According to the fundamental principles, a computer automatically analyzes a target person lip image shot by a camera, extracts a feature value of the lip shape, matches the extracted feature value with a lip shape model in a lip shape model library and then completes input of texts corresponding to the matched lip shape model. By means of the technical scheme, an effective solution is provided for transmission of verbal production orders in a production workshop site.
Description
Technical field
The present invention relates to human-computer interaction technique field, be specifically related to a kind of character input method based on lip image recognition.
Background technology
At a lot of workshop, there is larger noise in production environment, what this was serious hinders assigning of on-the-spot oral production ordering.
For solving the problem, the invention provides a kind of character input method based on lip image recognition, assigning efficiency for what promote the oral production ordering in production scene.
Summary of the invention
For the problems referred to above, the present invention is by gathering lip video image and utilizing video processing technique to carry out automatically measuring and the mode of mating with lip model to lip eigenwert, a kind of character input method based on lip image recognition is provided, thus promote production scene oral production ordering assign efficiency.
Concrete technical scheme provided by the invention is:
Based on a character input method for lip image recognition, it is characterized in that, the method comprises the following steps:
Video image acquisition, by the lip video image of camera collection target person;
Video analysis, is analyzed described lip video image according to image analysis technology by computing machine, obtains the eigenwert of lip;
Lip Model Matching, mates the eigenwert of described lip with the lip model in lip model bank;
Text event detection, according to the lip model of coupling, completes the input of word.
Each lip model in described lip model bank, word corresponding corresponding respectively.
Beneficial effect: a kind of character input method based on lip image recognition provided by the invention, is carried out automatic analysis by computing machine to lip image, extract the eigenwert of lip, lip eigenwert is mated, completed the input of word with lip model.This technical scheme is the transmission of producing the oral production ordering of plant site, provides a kind of effective solution.
Accompanying drawing explanation
It is workflow diagram of the present invention shown in Fig. 1.
Embodiment
In order to more specifically describe the present invention, below in conjunction with the drawings and the specific embodiments, technical scheme of the present invention is described in detail.
As shown in Figure 1, obtain the lip video image of target person with video camera, then carry out automatic analysis by computing machine lip image, extract the eigenwert of lip; By computing machine, the lip eigenwert of extraction is mated with the lip model in lip model bank again.In lip model bank, each lip is respectively to there being corresponding word.After finding the lip model matched, completed the input of word by the word that computing machine is corresponding according to the lip model of coupling.
As the further optimization to the present embodiment, the word of computer input, workshop electronic display shows, obtains associated production instruction in time to facilitate field staff.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
