Along with development of computer, used widely by the computer drawing personal portrait.At present, the automatic collection of known personal portrait or generation equipment all are based on a certainly with reference to photo usually, and relevant collecting device of utilization and Computer Analysis Calculation Method draw corresponding portrait data.These methods have obtained cognitive comparatively widely and utilization.It mainly is the analytical calculation that had existed picture and form thereof to differ from one another already to certain, thereby extracts the portrait data of this picture correspondence, and can be whole in the relevant enterprising step of equipment, adopts certain method to show again.But, existing method all is by the picture that had existed is already analyzed, at first to suppose the user had already outwardness with reference to photo, the right to use that also will have this photo simultaneously, if when the user never had individual photo or the current individual photo that can't obtain certain time period, cause the purpose that can't realize generating relevant portrait; Secondly, adopt the photo that had existed already as input and reference, this reference that had existed has already just become a limitation, removing has outside certain requirement form and sharpness as the reference photo, and the target portrait that the user obtained will be that the essential characteristic that is confined to described reference substantially generates.
In sum, present individual portrait automatic creation system has limitation on applicability, and therefore doing really needs further to improve.
Summary of the invention
Technical matters to be solved by this invention provides a kind of computer based method for drawing portrait, makes the user can gather and use individual portrait more easily.
For solving the problems of the technologies described above, a kind of method for drawing portrait provided by the present invention may further comprise the steps: by the portrait key element of artificial drafting quantity sufficient, and described portrait key element is prestored into computing machine; The user selects suitable portrait key element to form complete portrait by computing machine.
The mode that the present invention adopts traditional drawing to combine with computing machine, earlier by manually drawing out the portrait key element, this artificial portrait key element of drawing is imported computing machine, when the user need draw portrait, thereby promptly can therefrom select suitable key element to form complete portrait.Drawing personal portrait by this method need be based on existing photo, and whole drawing process is more convenient and effective.
Further improvement of the present invention is that described portrait key element is drawn by the sketch gimmick.Compare with adopting real pictures, the portrait key element that adopts the sketch gimmick to draw has better secret protection and interest; And compare with adopting the cartoon material, then have better emulation.
Further improvement of the present invention is, according to the similarity degree between the portrait key element that is prestored into database, gives continuous identification code for each portrait key element, makes it to form continuous key element spectral line.Based on the continuous key element spectral line of portrait key element, for the further analytical calculation between the portrait data that generated provides standardized basis.
Further improvement of the present invention is, for each portrait key element is given adjustable key element attribute.Described key element attribute comprises the position of portrait key element, size, length and width compression ratio, color and luster etc.
Further improvement of the present invention is, for the portrait key element with left-right symmetric type, limits the horizontal level operation of described portrait key element, makes the central lines of the center line and the face contour of described portrait key element.Like this, no matter how the user operates, revise, to move the portrait key element, the portrait key element of all left-right symmetric types is in the process that forms complete portrait, and its horizontal level all is coordination and mates, so just having saved a lot of time of user, is very big improvement for user's experience.

Fig. 3 is the second operation interface synoptic diagram of method for drawing portrait of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done description further.
The present invention is a kind of computer based method for drawing portrait, and it is mainly finished by following steps: earlier by artificial portrait key element of drawing quantity sufficient; The personal portrait key element is common shape of face, eyes, nose, lip etc., and as preferred embodiment of the present invention, all portrait key elements are all drawn by artificial sketch gimmick; Compare direct use real pictures and develop and come or directly adopt true man's portrait key element further to generate the method for individual portrait, sketch is drawn has sufficient secret protection and interest; Adopt the cartoon material further to generate personal portrait as personal portrait or cartoon material as the portrait key element and compare, sketch is drawn has better emulation again.
Again above-mentioned portrait key element of completing is prestored into computing machine, the foundation of portrait data and storage are based on the structured data format of each portrait feature category and attribute; Each key element of portrait to eyes 5, according to the mode of continuous subtle change, to another form, according to its similarity degree, is given continuous identification code respectively from a form as the eyes among Fig. 11, makes it to form continuous key element spectral line.As shown in Figure 1, eyes 1 are respectively eye-001 and eye-002 with the identification code of eyes 2, and the identification code on eyes key element spectrum differs a minimum base unit, and when then embodying, these two eyes key elements are the most similar.By that analogy, other each portrait key elements (shape of face, nose, face) all are like this, and on various successive lines, two portrait key elements with minimum identification code gap are the most similar.Based on the continuous key element spectral line of this kind portrait key element, for the further analytical calculation between the portrait data that generated afterwards provides standardized basis; For instance, if will compare two similarity degrees between the portrait, can pass through the identification code of a comparison portrait key element, thereby make the comparison of similarity degree quantitatively, and calculate the similarity value according to certain rule.
After the portrait data aggregation of having finished quantity sufficient, the user just can select suitable portrait key element to form complete portrait by computing machine.Consult shown in Figure 2, the first operation interface synoptic diagram of method for drawing portrait of the present invention, the user can select suitable portrait key element to form complete portrait under this interface.For example the user clicks " hair style ", then can demonstrate the sketch hair style that all have been prestored into database in drop-down menu, and the member selects suitable hair style therein, click selected after, this kind hair style will be loaded on the big frame on the right.So, can operate other each portrait key element equally, such as shape of face, eyes, eyebrows etc. are finished the drafting of whole personal portrait.Again as shown in Figure 3, the member can be further according to the guidance panel on the right, the property value of the portrait key element that loaded is adjusted etc., as adjusting the height of eyebrow, the width of face etc.User's drawing can be saved to server with data after finishing, and has promptly finished the collection to this portrait.
In the present invention,, limit the horizontal level operation of described portrait key element, make the central lines of the center line and the face contour of described portrait key element for portrait key element (as eyes) with left-right symmetric type.Like this, no matter how the user operates, revise, to move the portrait key element, the portrait key element of all left-right symmetric types is in the process that forms complete portrait, and its horizontal level all is coordination and mates, so just having saved a lot of time of user, is very big improvement for user's experience.Domestic consumer is not the professional; when its drawing portrait or operation; differ and reach level very accurately surely; the phenomenon that the portrait that occurs coordinating very much originally through regular meeting is disarrayed; such as nose or eyes are accidentally turned left or toward having moved right a little; user's panesthesia is imappropriate, but is difficult to find.Therefore the present invention defines the operation to the staple horizontal level, be symmetrical characteristics according to human portrait essence, start with from subtlety, solved problem technically, remedied user's deficiency in this respect, and improved the efficient of drawing portrait widely, the time of 60-180 second just can obtain complete realistic individual portrait sketch usually.
