In operation S220, text information and graphic frame information in the flowchart picture are respectively identified, where the text information includes text content and text coordinates, and the graphic frame information includes graphic frame content and graphic frame coordinates.

the method includes S310 to S330

Operation S310, dividing the flowchart picture into a text information picture and a graphic frame information picture;

and gridding the flow chart picture by a preset size. Sequentially judging the type of the grid according to the number of pixels in each grid, and when the number of pixels is larger than a preset threshold value, determining the type of the grid as the text information grid; and when the number of the pixels is smaller than a preset threshold value, the picture frame information grid is obtained. The combined text information grid forms a text information picture, and the combined graphic frame information grid forms a graphic frame information picture.

Operation S320, identifying a text information picture, and generating the text information;

as shown in fig. 4A, processing a text information area by an embodiment of the present disclosure includes: preprocessing the text information picture and generating a text coordinate; the textual content is identified and generated.

Through the embodiment of the disclosure, the text information picture is preprocessed to generate the text coordinate, and the preprocessing comprises the steps of correcting the inclination of the text information area and normalizing the scale. For example, for hand-drawn flow chart pictures, the characters are inclined to some extent when the pictures are taken, and the sizes of the characters are different during the writing process. After the text information area of the handwritten flow chart is obtained, inclination correction and scale normalization processing are required to be carried out on the text information area, so that the recognition error caused by character inclination is reduced, the size of the character is unified, and the subsequent recognition efficiency is improved.

According to the embodiment of the disclosure, the text information picture is preprocessed to generate the text coordinates, the text is cut according to the horizontal projection and the vertical projection of the text information picture, and the text coordinates are determined. For example, a text message picture is horizontally projected, an upper limit and a lower limit of each line of characters are found, and line segmentation is performed. And performing vertical projection on each cut line, finding the left and right boundaries of each character, and cutting the single character. The ordinate of each piece of text content is determined by the horizontal projection of the piece of text content.

As shown in fig. 4B, the processing of the graphic frame area by the embodiment of the present disclosure includes: preprocessing the graph frame information picture and generating a graph frame coordinate; and identifying and generating the graphic frame content.

According to an embodiment of the present disclosure, the graphics frame information picture is preprocessed and graphics frame coordinates are generated, including rectifying the graphics frame into an ideal geometric figure. For example, the irregular curve ab is adjusted to be a regular line segment a 'b', and the coordinate positions of the end points a 'and b' of the line segment are adjusted to be coincident with the end points of the adjacent line segment, so that a closed geometric figure is formed.

The preprocessing of the graphic frame information picture according to the embodiment of the present disclosure further includes cutting the graphic frame into individual graphic frame units. The segmentation method can be that a flow line is distinguished through the closeness characteristic of the graphic frame; and distinguishing the individual graphic frame units through the connectivity of the graphic frames.

According to an embodiment of the present disclosure, creating a graphic frame template includes creating a graphic frame template based on at least one set of test graphic frames. Each set of graphics boxes is shown in FIG. 7, and contains all the basic graphics boxes required to draw the flowchart. For example, 10 basic graphic frames drawn by persons are collected to obtain 10 groups of test graphic frames, and each group of test graphic frames contains all the basic graphic frames required for drawing the flow chart, and forms a graphic frame template.

According to the embodiment of the disclosure, a deep neural network-based graphic frame matching model is established, and a graphic frame template is input into the deep neural network graphic frame matching model for training and evaluation.

According to the embodiment of the disclosure, the identification of the graphic frame is to determine the category of the graphic frame according to the similarity between the graphic frame and each graphic frame in the graphic frame template.

It is understood that the graphic frame content of the disclosed embodiments may include: graphics category, graphics size, etc.

S130, matching the text content and the graphic frame content according to the text coordinate and the graphic frame coordinate to generate a data file;

according to the embodiment of the disclosure, the text content and the graphic frame content are matched according to the text coordinate and the graphic frame coordinate to generate the data file. And if the text coordinate and the graphic frame coordinate are not matched, adjusting the text coordinate and/or the graphic frame coordinate. For example, as shown in fig. 5A, when the text coordinate ordinate coincides with the graphic box ordinate, the text ordinate may be adjusted to reduce the height of the text so that all the coordinates of the text are inside the graphic box coordinate. Fig. 5B schematically shows that when a part of the set of abscissa of the text content is larger than the set of ordinate of the graphic frame, the abscissa on the right side of the graphic frame is adjusted to increase the area of the graphic frame so that all the coordinates of the text are inside the coordinates of the graphic frame.
