Flow chart reading method and device, electronic equipment and storage medium

The invention relates to the field of standard file digitization, in particular to a flow chart reading method and device, electronic equipment and a storage medium. The flow chart reading method comprises the following steps: carrying out binarization processing on a flow chart image to obtain a first processed image; negation operation is carried out on the first processed image to obtain a second processed image, and the negation operation comprises the steps that black pixel points in the first processed image are set to be white, and white pixel points in the first processed image are set to be black; and according to a connected domain in the second processing image, determining a corresponding relationship between graphs and characters in the flow chart image, the connected domain being a connected region with white pixel points. According to the process, the flow chart information is obtained by converting the flow chart image into the binary image with a simple mode of the second processing image, th
