Embodiment
Embodiment of the method
As shown in Figure 1, a kind of digital book drawing method, comprises the following steps;
S1, on assigned address, projection obtains perspective view, and writing-painting emits beam, and forms hot spot on perspective view, and writing-painting is write or painted, and hot spot moves on perspective view;
S2, according to preset frequency, take perspective view and form several single frames photographic images, determine in real time the position of hot spot and determine spot motion track by Continuous Tracking facula position;
S3, real-time continuous several single frames photographic images that superpose, obtain handwriting image, comprise person's handwriting pixel and non-person's handwriting pixel in handwriting image;
S4, handwriting image is superimposed on default Background, is about to person's handwriting pixel and is filled in Background and paints predetermined color, non-person's handwriting pixel is not filled, form thus the first blank map; Person's handwriting in the first blank map is carried out to translation processing according to the parallax value of setting, obtain the image after translation, the image after translation is defined as to the second blank map;
S5, according to specified format, the first blank map, the second blank map are fused into digital format figure continuous wave output;
S6, show digital format figure continuously, form the digital book picture of drawing.
Preferably, in step S2, the concrete operations of determining facula position are: the rgb value that extracts all pixels in every width single frames photographic map picture, rgb value to all pixels in single frames photographic map picture carries out gray processing, according to default gray processing threshold value, carry out the operation of gray processing Threshold segmentation, extract gray scale and be greater than the pixel of gray processing threshold value, and these gray scales are greater than to the position that the location positioning of the pixel of gray processing threshold value is hot spot.
Preferably, as Figure 2-3, in step S2, the concrete operations of Continuous Tracking facula position are: in the consecutive frame photographic images of the captured single frames photographic images obtaining, take the position of current hot spot is reference position, extract the connected domain that intensity is greater than gray processing threshold value nearby, with this, follow the tracks of the position of hot spot.
In this process, for real also original subscriber's painting and calligraphy person's handwriting, strengthen painting and calligraphy and experience, need to determine the position of hot spot, carry out spot location.
Spot location is the data by gathering, and accurately calculates facula position, and real-time follow-up, location spot all can show continuously, fast facula position while making user writing, drawing on digital indicator.
Quantity by hot spot on screen is divided, and spot location technology can be divided into single-point location and multipoint positioning technology, and single-point location technology refers to the location technology for a hot spot, and multipoint positioning refers to the location technology for a plurality of hot spots; By whether contact screen is divided, spot location technology can be divided into contact location and contactless location technology, contact location technology refers to the technology that hot spot positions by contact screen, and contactless location technology refers to the technology that hot spot does not position by contact screen.
The present embodiment is for above-mentioned two kinds of dividing condition, and the contactless single-point location technology of primary study, by spot location technology and digital convergence, to realize digitizing interaction.
Preferably, as shown in Fig. 4-5, need to determine whether person's handwriting has interruption in this process, there is interruption to repair, its concrete operations are: judge in consecutive frame photographic images, whether person's handwriting has interruption, if there is interruption, continue to judge whether the interruption distance of person's handwriting is less than default critical value, if being interrupted distance, person's handwriting is less than this critical value, in the direction of the center of gravity line of historical person's handwriting and current person's handwriting, the current person's handwriting of continuous compound rate, to discontinuities, divides discontinuities and is connected, supplements, thereby repairs disconnected pen; If person's handwriting is interrupted distance, be more than or equal to this critical value, do not repaired.
Person's handwriting reparation is a large outstanding technical characterictic of the present embodiment, can not only reproduce in real time person's handwriting, and can identify the handwriting and carry out certain repairing, the repairing of in the situation that determining that being interrupted part is disconnected pen, some less-than-ideal disconnected pens being carried out has embodied this method and has followed intelligentized trend.
Preferably, specified format refers to side-by-side form or dot-by-dot form.
The present embodiment is for coordinating the needs of digital indicator, and digital format is appointed as side-by-side form or dot-by-dot form, is understandable that, according to thinking of the present invention, digital format figure is appointed as to other form also within the scope of the invention.
In reality, while carrying out painting and calligraphy creation, pen acts on paper, at the edge of person's handwriting, conventionally all can occur a kind of effect of infiltration, and the color of person's handwriting, by dense thin out, successively to exosmosis, is given the visual experience of a kind of gradual change of people.
During for real simulation painting and calligraphy creation, pen acts on the effect of impregnation on paper, and the present embodiment also primary study edge weakens technology, for person's handwriting edge, weakens edge color, from depth to shallow, by dense thin out, gradual change successively, finally forms effect of impregnation.
