Embodiment Construction
[0040] The present invention will be further described below in conjunction with specific embodiments. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0041] With the major breakthroughs in artificial intelligence and convolutional neural network technology in recent years, technologies such as image recognition, target detection, and natural language processing have rapidly stepped out of the laboratory and been widely used. Among them, the text detection and recognition technology in natural scenes involves both image processing and natural language analysis, and has also made great progress. At present, it is possible to efficiently recognize and extract text in any direction in complex images. Therefore, under the background of this engineering practice and theoretical technology, the present invention proposes an intelligent verification metho...

The invention discloses a power equipment terminal strip wiring checking method and device. The method comprises the following steps: monitoring a terminal strip physical wiring graph uploaded by field engineering personnel; preprocessing a real object graph returned from the field; positioning a terminal row graph block in the preprocessed physical graph; identifying a terminal number and an external wiring label in an image block; aligning a terminal port and an external connection wire; arranging recognition and alignment results and generating structured information; retrieving schematic diagram information and comparing the schematic diagram information with actual wiring information to generate a diagnosis result; and collecting diagnosis information to generate a final report. According to the invention, an effective wiring terminal intelligent proofreading scheme is realized by utilizing an image processing technology and based on a text detection latest theory and a related method in a natural scene, the problems of high false identification rate, complex operation and scene limitation in a traditional automatic proofreading scheme are solved, the operation and maintenance cost is greatly reduced, and the productivity is truly liberated.
Description
technical field [0001] The invention relates to a method and device for checking terminal wiring of general power equipment, in particular to a method and device for checking wiring of terminal strips of power equipment based on natural scene text detection, and belongs to the technical field of wiring checking of power equipment. Background technique [0002] In the engineering acceptance of the power industry, it is necessary to check the wiring of the electrical cabinet. In the traditional mode, the acceptance personnel must compare the provided drawings with the actual objects to verify whether the wiring is correct. Due to the relatively dense terminal blocks, a high degree of concentration is required during the verification process, which is prone to errors. Considering that the wiring proofreading needs to process the schematic design diagram information and the actual wiring information on site at the same time, the schematic diagram is less disturbed, and the drawi...
