The invention relates to a pointer instrument reading identification method and device, computer equipment and a storage medium. According to the method, an image of a pointer instrument to be detected is obtained, and the image of the pointer instrument to be detected is determined according to a target detection algorithm; whether the image of the pointer instrument to be detected is matched with a preset template image is judged based on an acceleration robust feature algorithm, and if so, the key points of the image of the pointer instrument to be detected are determined according to the preset key points of the preset template image; the scale curve of the pointer instrument to be detected is constructed according to the key points; a suspected pointer point is determined according tothe gray values of the coordinate points on the scale curve; the pointer position of the pointer instrument to be detected is determined according to the gray value between a scale circle center point and the suspected pointer point; according to the pointer position, the reading of the pointer instrument to be detected is determined. The pointer instrument reading identification method providedby the invention has high inspection efficiency and accuracy for various pointer instruments.
Description
technical field [0001] The present application relates to the technical field of intelligent electric equipment, in particular to a method, device, computer equipment and storage medium for identifying readings of pointer meters. Background technique [0002] With the development of the power system, the requirements for the service quality and safe operation level of the power grid are constantly increasing. An important part of the power grid is all kinds of substations. To strictly ensure the stable and reliable operation of power equipment, regular inspections of power equipment are required. Substation inspection refers to the daily work of substations to conduct regular inspections, inspections and ensure the normal and reliable operation of power equipment within its jurisdiction. There are many equipment in the substation equipped with various pointer instruments, and the inspection of various pointer instruments is very important. [0003] In the traditional techn...
