Background technology
Drawing is many people art form loved by all, and the mode that main stream approach is painted on computers at present is to pass through electricity
Sub- paintbrush is painted on painting canvas, and this painting mode requires very high to the skill of drawing, for it is most of like drawing but not
Acquired a certain degree of difficulty for the user for the skill that is skilled in painting.
The method of existing electronic painting creation is all by being realized to the secondary editor of material, and the works of description all need
Conceive in advance in the brain of user, be short of in the interest of drawing and personalization etc..
The content of the invention
It is an object of the invention to for deficiency of the prior art, there is provided a kind of interactive mode based on sound intensity value is painted
Drawing method and device, to solve problems of the prior art.
Technical problem solved by the invention can be realized using following technical scheme：
A kind of interactive drawing method based on sound intensity value, comprises the following steps：
1) some painting elements are randomly selected；
2) collected sound signal, some frames are broken down into；Calculate the energy value of each frame voice signal, the energy value
For the quadratic sum of all sampled values in the frame, and centralization processing is done to the energy value, obtain the loudness value of voice signal；
3) loudness value is mapped to the painting element extracted in step 1), painting element carries out feature according to loudness value
Adjustment, the mathematical function of the Character adjustment are
Y=1/ [1+e^ (- x)]
Wherein, y represents the characteristic value of basic painting element, and x represents the loudness value of voice signal, and e herein represents nature
The truth of a matter of logarithm；
4) painting element after Character adjustment is shown on the display unit.
Further, the feature of the painting element includes shape, color, size, position and texture.
Further, the interactive drawing method also includes presetting drawing time and drawing number.
Further, the interactive drawing is carried out based on a device, and described device includes：
Collecting unit, it is used for collected sound signal, and the voice signal of collection is sent to computer；
Memory cell, it is used to be stored with painting element, random in the memory unit by computer when drawing starts every time
Extract several painting elements；
Computer, it is used for the energy value for by some frames of audio-signal resolution, calculating each frame voice signal, and to described
Energy value does centralization processing, obtains the loudness value of voice signal；The loudness value is used for one of painting element or one group
Feature carries out Character adjustment；
Display unit, its painting element being used for after Character adjustment.
Further, the display unit includes electronic-paper display screen, cathode-ray imaging display, liquid crystal display and laser
Projection device.
Compared with prior art, the beneficial effects of the present invention are：
Loudness value based on sound, and loudness value is converted into the feature of painting element so that draw individual character is presented every time
Picture change, unduplicated.
Brief description of the drawings
Fig. 1 is the schematic diagram of the interactive drawing method of the present invention based on sound intensity value.
Embodiment
To be easy to understand the technical means, the inventive features, the objects and the advantages of the present invention, with reference to
Embodiment, the present invention is expanded on further.
Referring to Fig. 1, a kind of interactive drawing method based on sound frequency value of the present invention, comprise the following steps：
1) some painting elements are randomly selected；
2) collected sound signal, some frames are broken down into；Calculate the energy value of each frame voice signal, the energy value
For the quadratic sum of all sampled values in the frame, and centralization processing is done to the energy value, obtain the loudness value of voice signal；
3) loudness value is mapped to the painting element extracted in step 1), painting element carries out feature according to loudness value
Adjustment, the mathematical function of the Character adjustment are
Y=1/ [1+e^ (- x)]
Wherein, y represents the characteristic value of basic painting element, and x represents the loudness value of voice signal, and e represents natural logrithm
The truth of a matter；
4) painting element after Character adjustment is shown on the display unit.
Collecting unit, it is used for collected sound signal, and the voice signal of collection is sent to computer；
Memory cell, it is used to be stored with painting element, random in the memory unit by computer when drawing starts every time
Extract several painting elements；
Computer, it is used for the energy value for by some frames of audio-signal resolution, calculating each frame voice signal, and to described
Energy value does centralization processing, obtains the loudness value of voice signal；The loudness value is used for one of painting element or one group
Feature carries out Character adjustment；
Display unit, its painting element being used for after Character adjustment.
The technical characteristic implication that the above method and device include is as follows：
Sound：Refer to voice, natural phonation, artificial sound.
Loudness value：It is multiframe by audio-signal resolution, each frame length is 20ms as usual.For each frame, this is calculated
The energy value (quadratic sum of each sampled value) of frame acoustic information, (it is 0 that energy value is mapped as into average for energy value centralization processing
Numerical value) after, the loudness value as this frame voice signal.
