Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings, but it is not intended to limit the present invention.

[0027] Due to the influence of rhythm in sign language expression, head movement will produce amplitude changes, so combining the use of the head to improve the sense of reality of sign language expression becomes one of the innovative points of the present invention.

[0028] Such as figure 1 As shown, a method for synthesizing rhythmic head motion based on motion offset mapping according to an embodiment of the present invention includes the following steps:

[0029] Step 101, input the natural text to be processed into the sign language markup language system, and the sign language markup language system generates the content information, prosodic structure and prosodic mark of the processed natural text.

[0030] The sign language markup language system described in step 101 in this embodiment adopts...

Abstract

The invention discloses a rhythmic head motion synthesis method based on motion deviation mapping. The method comprises the following steps of: inputting the natural text to be processed into a sign language markup language system, wherein the sign language markup language system analyzes to generate the content information, rhythm mark and rhythm structure of the processed natural text; setting a parameter and a corresponding value, reading the gesture data of the word corresponding to the content information of the natural text from the database in the sign language markup language system, normalizing the dynamic time of the degree of freedom of the head joint, reading the parameter value, and processing the gesture data of the word corresponding to the content information of the processed natural text by a motion deviation mapping method to obtain the motion information after amplitude change; and obtaining the sign language animation demonstration information of the natural text by matching the motion information after amplitude change with the rhythm structure of the processed natural text. Through the invention, the sense of reality of the sign language animation can be enhanced, and the intelligibility of the sign language animation can be improved.

Description

technical field [0001] The invention belongs to the technical field of sign language application, and in particular relates to a rhythmic head motion synthesis method based on motion offset mapping. Background technique [0002] As a visual language, sign language is expressed through the cooperation of multiple modes such as hands, head, face and body. Gesture expression effects are also different in different contexts, usually reflected in prosodic features such as amplitude, speed, and rhythm. In order to synthesize a realistic virtual human animation, the use of capture technology based on real human motion can solve this problem, but the disadvantage is that if you want to generate a slightly changed motion relative to the original captured data, you have to go through the process of motion capture again. The volume is so huge that it is not suitable for real-time virtual human animation. How to synthesize realistic and expressive sign language animations based on ori...
