In this embodiment, a method for copying paper calligraphy works is provided, and fig. 1 is a flowchart of a method for copying paper calligraphy works according to an embodiment of the present application, and as shown in fig. 1, the flowchart includes the following steps:
step S102, the client software photographs calligraphy works to obtain images, wherein the client software is installed on a mobile terminal, and the calligraphy works comprise at least one of the following: paper calligraphy works, calligraphy works engraved on the real objects, and calligraphy works written on the real objects;
step S104, the client software scans a two-dimensional code and opens a page provided with an uploading control, wherein the two-dimensional code is a link carrying identification information of the calligraphy works, and the link points to the page;
step S106, the client software uploads images through the control;
step S108, the server software receives the image and the identification information and obtains character information corresponding to the identification information according to the identification information; the character information comprises the distances between four points on each word in the calligraphy works stored in advance, the distances between the four points on each word and the four points on adjacent words, and the four points on each word are respectively the leftmost point, the rightmost point, the topmost point and the bottommost point of the word; in a preferred embodiment, when there are a plurality of leftmost points, rightmost points, uppermost points, or lowermost points on each word, a point whose position is shifted is selected from among the leftmost points, a point whose position is shifted is selected from among the rightmost points, a point whose distance difference between the distance from the point to the leftmost point and the distance from the point to the rightmost point is the smallest is selected from among the uppermost points, and a point whose distance difference between the point and the rightmost point is the smallest is selected from among the lowermost points.
The manner in which four points are selected from each word may be selected using manual labeling. In this case, as an optional embodiment, the distance between these points is previously measured manually and inputted into the server.
As another example, this may be done by way of machine learning. And establishing a second model for machine learning of the neural network, wherein the second model is obtained by training a plurality of groups of training data, each group of the plurality of groups of training data comprises preset input data and output data corresponding to the input data, the input data comprises Chinese characters, and the output data is the positions of four points of the Chinese characters corresponding to the input data. After the second model is trained, Chinese characters are input into the second model, and the positions of the corresponding four points can be obtained. At this time, the distance between the first point and the second point of the first character is taken as a standard distance, and all distances in the calligraphy work are multiples (including integer multiples and decimal multiples) of the standard distance. The corresponding ratio is thus easily obtained.
Step S110, the server software obtains a first proportion of the distance between four points of each word and a second proportion between four points of each word and adjacent words according to the character information;
as an optional implementation, the server obtains the text in the image from the image, and converts each text into vector path information. There are various ways to convert to vector path information, example 1: and adjusting brightness and/or contrast of the image, recognizing characters in the image by using character recognition once the image is adjusted, comparing the recognized characters with characters in the calligraphy works stored in a database in advance, and stopping adjustment if the recognized characters are correct. If the recognition is wrong, the brightness and/or contrast is continuously adjusted until the recognition is error-free. And performing binarization processing on the adjusted image, drawing a path at the joint of black and white pixels of the binarized image, and converting the drawn path information into vector path information.
Example 2: this can be done by way of machine learning. Establishing a first model for neural network machine learning, wherein the first model is obtained by training a plurality of groups of training data, each group of the plurality of groups of training data comprises preset input data and output data corresponding to the input data, the input data is an image comprising Chinese characters, and the output data is vector path information of the Chinese characters corresponding to the input data. After the first model is trained, the image is input into the first model, and corresponding vector path information can be obtained.
As an optional implementation, the vector path information obtained through the two examples is compared, and if there is a difference between the two vector path information, the average value is taken as the final vector path information. The vector path information obtained in this way is more accurate.
The obtained vector path information may be stored in a database of the server side, and the generation time of the vector path information is stored. When another client software uploads the image by scanning the two-dimensional code next time, the saved vector path information is directly used.
In step S112, the server software adjusts the size and the position of the word on the image according to the first ratio and the second ratio. In the case where the vector path information is obtained in step S110, the vector path information of each word is adjusted to adjust the size and position of the word on the image.
Preferably, after step S112, the server software may further send the adjusted image to the client software, and the client software sends the adjusted image to a printer for printing.
As an alternative, the number of the images sent by the server software to the client software may be two, the first image is adjusted based on the original image, and the background information in the image is saved. And the second step is that the vector information is used for generating patterns, the paths surrounded by the vector information are filled with colors to generate character images, and the character images and the background images are combined to generate images with the same size as the original images. At this time, which image to print may be selected, wherein the second image is a sharper image. The first image is more memorial.
As another optional implementation, when filling color, for each path of the word to be filled, obtaining a value of each pixel point of the word in the original image, calculating an average value of all pixel points of the word, and filling the path of the word using the average value.
As another optional implementation, the text image is generated into a text image with a transparent background, a group photo of the user and the calligraphy work is shot through client software, and the text in the text image with the transparent background is faded and added to the background of the group photo. Through the processing mode, a tourist photo with memorial significance is obtained.
Through the steps, the photos shot by the calligraphy enthusiasts are processed by the server to be closer to the original taste of the calligraphy works, so that the problems that the calligraphy works shot by the calligraphy enthusiasts are unclear or the fonts are distorted when the calligraphy works are printed on paper are solved, and the calligraphy works are more clearly restored on the paper.
