Embodiment Construction

[0019] Attached below figure 1 , attached figure 2 The present invention will be further described.

[0020] A method for identifying the position of a band switch of an instrument comprises the following steps: a) collecting original images of the outer surface of the instrument, and inputting the collected original images into a computer. b) Use the computer to grayscale the original image to convert the original image from a color image to a grayscale image. Since the color image is generally in RGB format, that is, each pixel is composed of R (red), G (green), and B (blue). Color) consists of three components. For 24-bit true color, each component is represented by 1 byte. The data storage is large and difficult to handle, so it is necessary to convert the color image to a grayscale image. Grayscale images only contain brightness information, not color information, thus reducing the amount of data processing by the computer. c) Binarize the grayscale image by computer,...

Abstract

A method for recognizing the position of a band switch of an instrument, comprising the following steps: inputting a collected original image into a computer and converting it into a grayscale image; performing binarization processing on the grayscale image; establishing rectangles respectively outside the contour; calculating the center of the band switch knob ; The computer calculates the gray value of the image at the center of the band switch knob, and calculates the difference between the gray values ​​of M pixels of the image in the rectangular area where the contour of the band switch knob is located and the gray value of the center of the band switch knob, The area formed by the P pixels with the largest difference is the indication mark of the band switch. The computer converts the M pixel points of the image in the rectangular area where the contour of the band switch knob is located from the plane rectangular coordinates to polar coordinates, and obtains the derivatives of the M pixel points to obtain the Y pixel points with the largest derivative value and the Y pixel points. The derivative values ​​of each other are the same, and the closed area between the Y pixels is the indicator of the band switch.

Description

technical field [0001] The invention relates to a method for identifying the position of an instrument band switch. Background technique [0002] At present, the indication recognition for pointer instruments is basically aimed at the dial scale and pointer of the instrument, but many instruments, especially analog instruments, also have various band switches on the panel. The function and range selected by the band switch can be read correctly in combination with the meter head. . The existing identification method cannot identify the position of the band switch. Contents of the invention [0003] In order to overcome the deficiencies of the above technologies, the present invention provides a method for accurately extracting the position of the instrument band switch. [0004] The technical scheme that the present invention overcomes its technical problem adopts is: [0005] A method for identifying the position of an instrument band switch, comprising the steps of: ...
