Abstract

The present invention provides a kind of human face cartoon animation image design method, and step is：1st, human face photo is obtained；2nd, several characteristic points of photo are gathered, the characteristic vector of face is constructed using characteristic point, establish face character topological diagram, represent the topological structure between each organ of face, it has certain tolerance to Facial metamorphosis, one characteristic vector of each vertex representation in topological diagram, for recording feature point the summit annex characteristic information；3rd, the characteristic vector with reference to face, face character topological diagram, the contour line line of curvature of face establish cartoon animation image database；4th, characteristic point is compared with database, extraction animation image；5th, cartoon animation image is rendered, special effect processing, generates the face of cartoon character moulding；6th, the key message of cartoon character moulding face is detected, is output to mobile terminal.This method realizes the visualization of face animation, solves the problems such as face lines ossify, be mechanical, meets the recreational demand of user.

Description

A kind of human face cartoon animation image design method
Technical field
The invention belongs to cartoon design field, more particularly, to a kind of human face cartoon animation image design method.
Background technology
Animation making is the new industry of our countries, wherein the design and application for human face cartoon are just extensively by joyous Meet.At present, human face cartoon cartoon design is typically after face characteristic is extracted, and retains human face feature, obtains human face sketch Portrait painting first sample, processing is then carried out to first sample and obtains human face cartoon.But the human face cartoon of generation, gathered with photo or video recording It is larger compared to gap, and lines are rigid, mechanical, stiff, can not meet the recreational and interactive demand of user.Therefore, grind It is a urgent problem to be solved to send out human face cartoon animation image design method a kind of.
The content of the invention
In view of this, the present invention is directed to propose a kind of human face cartoon animation image design method, vivid, lively can set Count out human face cartoon image.
To reach above-mentioned purpose, the technical proposal of the invention is realized in this way：
A kind of human face cartoon animation image design method, comprises the following steps：
1st, facial image or photo are obtained；
2nd, several characteristic points of facial image/photo are gathered, the characteristic vector of face is constructed using characteristic point；Pass through Characteristic point, face character topological diagram is established, represent the topological structure between each organ of face, it has certain for Facial metamorphosis Tolerance, one characteristic vector of each vertex representation in topological diagram, for recording feature point the summit annex feature Information；
3rd, the characteristic vector with reference to face, face character topological diagram, the contour line line of curvature of face establish cartoon animation shape Image data storehouse；
4th, characteristic point is compared with the data in cartoon animation image database, extraction characteristic point combination similarity surpasses Cross 80% animation image；
5th, the cartoon animation image in database is combined with face verification, and cartoon animation image is rendered, be special Effect processing, texture mapping, generate the face of cartoon character moulding；
6th, the key message of cartoon character moulding face is detected；
7th, if you have questions, repeat the above steps；If there is no problem, the face by cartoon character moulding is output to mobile terminal.
Further, this method also carries out marking to the cartoon character moulding face for being output to mobile terminal including user and commented Valency, obtain the satisfaction of user.
Further, facial image or photographic intelligence are obtained by the camera on mobile terminal.
Further, the characteristic point comprises at least eyes, nose, mouth, chin and forehead.
Further, the special effect processing includes rendering with water and ink making, Cartoon shading, water ripples production etc..
Further, the key message of the animation image includes profile information, bone information and lines information.
Relative to prior art, human face cartoon animation image design method of the present invention has the advantage that：Pass through Acquisition for mobile terminal facial image or photo, characteristic point is extracted, the characteristic vector of face is constructed using characteristic point, establishes face Attribute topological diagram, characteristic point is compared with the data in cartoon animation image database, extraction animation image；Realize face The visualization of animation, solve the problems, such as that face lines are rigid, mechanical, stiff, meet the recreational and interactive demand of user.
Brief description of the drawings
The accompanying drawing for forming the part of the present invention is used for providing a further understanding of the present invention, schematic reality of the invention Apply example and its illustrate to be used to explain the present invention, do not form inappropriate limitation of the present invention.In the accompanying drawings：
Fig. 1 is the schematic flow sheet of the embodiment of the present invention.
Embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the present invention can phase Mutually combination.
Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
A kind of human face cartoon animation image design method, comprises the following steps：
1st, facial image or photo are obtained by the camera on mobile terminal.
2nd, several characteristic points of facial image/photo are gathered, the characteristic point comprises at least eyes, nose, mouth, chin And forehead；The characteristic vector of face is constructed using characteristic point；By characteristic point, face character topological diagram is established, represents face Topological structure between each organ, it has certain tolerance for Facial metamorphosis, each vertex representation one in topological diagram Individual characteristic vector, for recording feature point the summit annex characteristic information.
3rd, the characteristic vector with reference to face, face character topological diagram, the contour line line of curvature of face establish cartoon animation shape Image data storehouse.
4th, characteristic point is compared with the data in cartoon animation image database, extraction characteristic point combination similarity surpasses Cross 80% animation image.
5th, the cartoon animation image in database is combined with face verification, and cartoon animation image is rendered, be special Effect processing, texture mapping, generate the face of cartoon character moulding；The special effect processing include rendering with water and ink making, Cartoon shading, Water ripples production etc..
6th, the key message of cartoon character moulding face is detected；The key message include profile information, bone information and Lines information.
7th, if you have questions, repeat the above steps；If there is no problem, the face by cartoon character moulding is output to mobile terminal.
8th, user carries out marking evaluation to the cartoon character moulding face for being output to mobile terminal, obtains the satisfaction of user Degree.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention God any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection with principle.
