Abstract

According to the embodiment of the invention, the method comprises the steps: acquiring the image information including a to-be-detected object, performing image opening operation on the image information to highlight the to-be-detected object, and obtaining object highlighted image information; executing a straight line segment detection operation on the object highlighted image information by using a straight line segment detection algorithm, and determining all straight line segment objects in the object highlighted image information; executing a straight line segment reconstruction operation on all the straight line segment objects by using a closed suppression combinatorial algorithm, and determining the to-be-detected object in the image information. Therefore, image processing and object detection can be automatically carried out on the image information so as to determine the overlapped irregular non-closed object in the image information, and compared with algorithms in the prior art, the method has higher detection accuracy and detection efficiency for the overlapped irregular non-closed object, the investment of manpower and material resources can be greatly reduced, the error rate is reduced, and the drawing auditing efficiency is improved.

Description

Technical field [0001] The present invention relates to the field of data processing, and more particularly to a method and apparatus for overlapping irregular non-enclosed objects. Background technique [0002] The compliance review of engineering design drawings is a common requirement, such as the normative review of graphics, tables, texts in the design drawings in the telecommunications design. The review involves whether the graphic object meets the requirements of the graphics, determined The association relationship between the object, and the like. This part of the work is mainly composed of manual completion and cost. Recently, the state puts forward AI's strategic construction, and the development of manual review and intelligent audit is bound to become trend. [0003] One of the points of the intelligent audit is the detection of the graphic object, the industry is more likely to achieve some simple objects, such as circles, triangles, etc., which constitutes a close...
