Title:
METHOD FOR COMPARING FITTINGNESS OF TWO-DIMENSIONAL DRAWING IN ENGINEERING
Document Type and Number:
WIPO Patent Application WO/2018/184282
Kind Code:
A1
Abstract:
A method for comparing the fittingness of a two-dimensional drawing in engineering, at least comprising the following steps: A. obtaining vector and bitmap information of a standard drawing which serves as a foundation and of a project drawing; B. carrying out hash operation on entity types and characteristic points in the vector and bitmap information, and comparing project information of the same hash value; C. calculating at least one or more pieces of information out of an entity change percentage, an area difference percentage, a manual intervention area change percentage and a pixel difference percentage according to the comparison result; and D. obtaining drawing fittingness information according to the obtained information and difference entity weight information. The described method only compares the same parts of a project drawing and a standard drawing, that is, the ratio of an entity in the project drawing that is the same as that in the standard drawing multiplied by a corresponding layer weight value to the total entity in the standard drawing multiplied by a corresponding layer weight, thus ensuring a good fit between the comparison result and a comparison made by a person.
