Referring to fig. 1, fig. 1 is a schematic flow chart of an animation generation method of a singeing machine for printing and dyeing fabrics, which comprises the following steps:
step S100, acquiring a station physical image containing a fabric to be printed and dyed;
Step S200, determining the area of the fabric to be printed in the station physical image, taking the area as the area of the fabric to be printed, and taking the area outside the area of the fabric to be printed in the station physical image as a scene image;

step S410, determining combustion areas of a plurality of continuous frame flame images;

Step S441, calculating the outer edge EC of the burning area C with single pixel width according to the mask of the virtual image I;
where Φ=i-C, I represents the virtual image, C represents the combustion area, EC represents the outer edge of the combustion area, Φ represents the scene image (which remains unchanged throughout the step).

Specifically, starting the search from the upper left corner of virtual image I, each ψ q e Φ, calculating the pixel gap d (ψ q,ψPmax), determining the most similar pixel block ψ qmin, where ψ qmin(d(ψqmin,ψpmin)＝min{d(ψq,ψpmin)},ψq e Φ), filling the unknown points in ψ pmax with ψ qmin; d (ψ qmin,ψpmin) denotes the gap between pixel blocks ψ qmin and ψ Pmax; d (phi q,ψPmax)＝∑(a(i,j)-b(i,j))2, the total number of the components is,
It should be noted that each point in the pixel block ψ q must be in the scene image Φ, and the pixel block ψ qmin closest to ψ pmax needs to be selected from the scene image Φ, so that d (ψ qmin,ψq) is minimum. The matching between conventional pixel blocks can only compare the values of the pixels already in the psi qmin. However, this embodiment uses pixel blocks for pixel level restoration, and performs basic estimation of the internal color information for the unknown region Ω, so that a closer pixel block ψ p can be found.
In step S446, the confidence of the points in ψ Pmax is updated, and it is determined that the points of the combustion area C are all filled, if yes, the process goes to step S441, otherwise, a composite image is output.
It should be noted that, after the unknown region in the pixel block ψ pmax is filled, the confidence coefficient C (p) of the pixel point in the pixel block ψ pmax is updated, and the formula for updating the confidence coefficient C (p) is: c (q) =c (qmin),In the course of the repair, as the pixel confidence C (p) decays, it is shown that the closer to the center of the unknown region C, the lower the confidence in the pixel information.
The present embodiment expands pixels according to the contour direction in the neighborhood block p of the outer edge point p based on the sampling of the contour in the pixel block. The confidence C (p) may be regarded as a measure of the trusted information for the neighborhood psip p of the point p. The purpose of using the confidence C (p) is to prioritize the best-known pixel points ψ p. The earlier the filled points the higher their confidence. For example, at the corner, block ψ p, the greater its C (p), the more likely it is to be filled in preferentially; in contrast, the smaller the block ψ p at the gentle edge, its C (p) will be filled later.
As a further improvement of the above embodiment, the confidence coefficient C (p) at any point p is calculated as:
Wherein f p is the number of pixels that have been filled in the neighborhood ψ p of point p; the I phi p is the number of pixel points in the field phi p;
As a further improvement of the above embodiment, the data item D (p) of each point p on the outer edge EC of the combustion zone is calculated by:
step S4421, calculating the gradient of each point p on the outer edge EC And gradient ofVertical gradient of 90 ° vertical
Step S4422, calculating n p,np is to calculate the normal of the point p on the outer edge EC in the neighborhood ψ p of the point p;
step S4423, according to the formula (E.g., let α=255), the data item D (p) is calculated.

6. The animation production method of a singeing machine for printed fabrics according to claim 5, wherein the confidence coefficient C (p) of any point p is calculated by the following formula:
Wherein f p is the number of pixels that have been filled in the neighborhood ψ p of point p; the |ψ p | is the number of pixel points in the field ψ p.
7. The method for generating the animation of the singeing machine for dyed fabrics according to claim 5, wherein the data item D (p) of each point p on the outer edge EC of the burning zone is calculated by:
calculating the gradient of each point p on the outer edge EC And gradient ofVertical gradient of 90 ° vertical
Calculating n p,np is to calculate the normal of the point p on the outer edge EC in the neighborhood psi p of the point p;
according to the formula The data item D (p) is calculated.
8. An animation producing device of a singeing machine for printed and dyed fabrics, characterized by comprising:
At least one processor;
At least one memory for storing at least one program;
The at least one program, when executed by the at least one processor, causes the at least one processor to implement the animation generation method of a printed fabric singeing machine as claimed in any one of claims 1 to 7.
9. A computer-readable storage medium, wherein the computer-readable storage medium has stored thereon an animation production program of a textile singeing machine for printing, which, when executed by a processor, implements the steps of the animation production method of the textile singeing machine for printing of any one of claims 1 to 7.
