Embodiment Construction

[0086] An intelligent identification method for a pointer instrument, such as figure 1 shown, including the following steps:

[0087] Step 101: Perform image clipping on the input image according to the recognition range set by the instrument parameter model, and perform distortion correction on the skewed image according to the skew angle set by the instrument parameter model.

[0088] Specifically include the following steps:

[0089] Step 10101: Perform image clipping on the input image according to the recognition range set by the instrument parameter model.

[0090] Step 10102: The skewed image is corrected for distortion according to the skew angle set by the instrument parameter model.

[0091] In the process of image preprocessing, distortion correction is performed on the image:

[0092] Distortion is that various distortions (distortions) often occur in the process of image acquisition or display: geometric distortion, grayscale distortion, and color distortion. ...

Abstract

The invention discloses an intelligent identification method of a pointer instrument, which comprises the following steps: carrying out image clipping on an input image according to an identificationrange set by an instrument parameter model, and carrying out distortion correction on a deflected image according to a deflection angle set by the instrument parameter model; carrying out image preprocessing on the corrected image: carrying out hough straight line detection on the preprocessed image to obtain the position of each straight line in the image; judging and filtering each straight lineaccording to parameters of the instrument parameter model, and finding out a pointer straight line; determining the direction of the pointer straight line according to the found pointer straight linein combination with the instrument parameter model; and according to the instrument range parameters of the instrument parameter model and the direction of the pointer straight line, calculating an instrument reading, and outputting a result. The invention provides the intelligent identification method of the pointer instrument, which is high in algorithm execution speed and good in identification effect.

Description

【Technical field】 [0001] The invention belongs to the technical field of artificial intelligence, and specifically refers to an intelligent identification method of a pointer instrument. 【Background technique】 [0002] The substation intelligent auxiliary system is the demand of the modern development of the substation. Through the front-end collection, combined with the platform intelligent video, artificial intelligence recognition algorithm and platform big data analysis model, the intelligent video monitoring and inspection of the substation are realized, and the readings of the instruments are analyzed. The equipment status is analyzed and alarmed, thereby reducing the number of manual inspections and abnormal inspections at the station, improving the efficiency and quality of operation and maintenance work, and replacing inspection personnel for inspections to ensure the safe operation of the power supply system. [0003] The traditional intelligent recognition algorit...
