S11, positioning a target page of the aircraft manufacturing and modifying range list through the tag information. It should be noted that the content in the existing list of the aircraft manufacturing and modifying range includes a data table, where the data table includes a table name and a field name, where the field name is a flight material number or a work order number, where the work order number is a drawing number or a work order number, where the table name may be referred to as tag information, and the tag information is located on a target page, and the field name is associated with the work order content.

S52, positioning to a sub-graph position (sub-graph drawing coding position) according to the sub-graph position coding, wherein the sub-graph drawing coding positioning method comprises the following steps: the subgraph drawing code is positioned through drawing coordinates, the drawing coordinates refer to the intersection points of the x and y axes of the drawing, the x and y axes of each drawing are coordinate values which are symmetrical by letters and numbers on the left and right and up and down of the drawing respectively, and the intersection points of the coordinate values are coordinate values; if taking the position code 41D25 as an example, 41 represents the number of the sub-drawing, D is the x-axis coordinate, and 25 is the y-axis coordinate; the positioning method is as follows: determining the position where the coordinate is the intersection of the X-axis coordinate D point and the Y-axis coordinate 25 point, namely the position point of the 41 th drawing number of the sub-drawing), scanning the drawing by taking the position where the drawing code of the sub-drawing is located as a base point, calculating the distance of a blank area along the scanning direction when the blank area is scanned, if the distance of the blank area is greater than a set boundary value, converting the scanning direction, continuing to scan by taking the position where the sub-drawing number is located as the base point, and continuing to scan when the content is scanned.
S53, when the blank area is scanned, calculating the blank area distance by taking the boundary position of the non-blank area and the blank area as a starting point, and if the blank area distance is larger than a set boundary value, taking the boundary position as a sub-image boundary point.
And S54, when the scanning is finished, connecting the boundary points of the subgraphs to form a closed graph, and taking the enclosed closed graph as the boundary of the subgraph.
