S22, respectively straightening the shear wall contour in the reinforcement diagram and the shear wall contour in the construction diagram along the corresponding longest edges;
the alignment along the corresponding longest side is represented by alignment in an XOY coordinate, and the longest side is selected for alignment because the longest side can generally indicate the longitudinal direction of the graph, the shear wall contours are aligned according to the longest side, namely, the shear wall contours are aligned according to the longitudinal direction, and alignment comparison is convenient when the shear wall contours are rotated at right angles subsequently; and because the longest sides of the shear wall profile in the construction drawing and the shear wall profile in the reinforcement drawing are not the same side, the shear wall profile and the shear wall profile in the reinforcement drawing can be different by 0-3 times of 90 degrees or 0-3 times of 90 degrees after mirror image after being respectively aligned along the longest sides. If the longest edge has the same plurality of edges, one edge is randomly selected to be aligned, and the subsequent edge can also rotate at right angles, so that the subsequent determination and comparison of the longest peripheral edge and the adjacent edge are not affected.
