Embodiment 1

[0039] refer to Figure 1 to Figure 7 A method for converting sign language motion information based on spatial coding into text information: firstly establish text information, sign language coding information and action animations to establish a sign language dictionary database corresponding to the sequence, and the implementation method includes the following steps:

[0040] (1) Signal data acquisition: According to the baud rate of the data glove on the wearer and the position tracker, the data frame of the time period is obtained, and a series of vector data of the input data is obtained;

[0041] (2) Data preprocessing: according to the sign language habit of the wearer of the data glove, define the curvature value range, and use the position tracker to divide the space area according to the individual characteristics of the wearer, locate the mouth, left earlobe, right earlobe, The position of the left and right shoulders;

[0042] (3) Feature extraction of sign langu...

Embodiment 2

[0064] refer to Figure 1-Figure 7 A method for converting text information based on spatial coding into sign language motion information. First, text information, sign language coding information and action animations are set up to establish a sign language dictionary database corresponding to the sequence. The implementation method includes the following steps:

[0065] (1) According to the skeleton parameters of the virtual human, the demonstration space of the virtual human is set, and the demonstration space of the virtual human is defined by space division rules;

[0066] (2), record the center position of the moving palm in each area in the demonstration space and the matrix of the relevant bone positions;

[0067] (3), using the input information as a keyword to search in the sign language dictionary database, and if relevant information is retrieved, the sign language coding information is extracted;

[0068] (4) According to the sign language coding information, set...

Abstract

The invention relates to a space encoding-based method for realizing interconversion between sign language motion information and text message, which comprises the following steps: firstly, establishing a sign language dictionary database for establishing corresponding sequences of the text message, sign language code message and action animation; and secondly, performing intelligent sign languageidentification according to a glove which is a data glove for detecting hand gesture changes of a user and a position tracker for detecting the space region of hand of the user, wherein the intelligential identification comprises that a sign language motion information to text message conversion module and a text message module to sign language information conversion module. The invention provides a space encoding-based method for realizing the interconversion between the sign language motion information and the text message, which has the advantages of high speed, strong instantaneity, and low cost.

Description

technical field [0001] The invention relates to a method for realizing real-time communication between a deaf-mute person and a normal person, in particular to a sign language communication method. Background technique [0002] Sign language is the language used by deaf people. It is a relatively stable expression system composed of hand movements supplemented by facial expressions, and a special language that communicates by movement / vision. There are more than 20 million hearing-impaired people in our country, and they mainly use sign language to communicate. Since sign language is not the common language of most people in the society, this restricts their communication with the society to a great extent. The development of the sign language communication system can solve this problem to a certain extent, play an important role in creating a barrier-free environment for the deaf, and play a great role in promoting standardized Chinese sign language. [0003] With the in...
