Description

Technical Field

[0001] The present invention relates to the field of electronic electricity meters, and more particularly to an electronic electricity meter. Background Art

[0002] An electronic meter is a device used in circuit systems. It utilizes a contactless remote control card. Its fully enclosed structure completely eliminates the risk of damage to the meter's card holder by high-voltage attacks, the insertion of hard objects such as iron, copper, or wooden sticks into the card slot, or the use of water, leading to potential theft. This provides a flexible installation environment, eliminating restrictions on height, distance, and other factors. Infrared-controlled electronic meters can be upgraded to a single card for water, electricity, and gas billing, enabling modern integrated property management without replacing meters. This highly targeted approach reduces renovation costs. The meter can be replaced directly, eliminating the need for cutting slots in the meter box or raising the meter base, saving manpower, money, material resources, and time, resulting in significant economic benefits.

[0003] Currently, the image processing performed on the working scene images of the electronic meter does not take into account the visual characteristics of the electronic meter itself, resulting in the image processing performed on the working scene images of the electronic meter not matching the visual characteristics of the electronic meter itself, which in turn causes the image processing effect to fail to meet expectations or causes the image processing computational complexity to be huge. Summary of the Invention

[0004] In order to solve the technical problems in the related fields, the present invention provides a block size selection system for an electronic meter, which uses an electronic eye imager to perform a bird's-eye shooting action on the environment where the surface of the electronic meter is located to obtain and output a corresponding real-time bird's-eye picture, and also performs nonlinear transformation processing using an exponential function, morphological processing of first expansion and then corrosion, and distortion calibration processing on the real-time bird's-eye picture in sequence to obtain and output a terminal enhancement picture with more reliable quality, and also parses the surface imaging area in the received terminal enhancement picture according to the standard contour pattern of the surface of the electronic meter, and uses the number of pixel rows and the number of pixel columns occupied by the surface imaging area as the first number and the second number, respectively. The number is output, and the height value of the reference block used for performing intra-frame coding on the entire real-time overhead picture in the vertical direction is determined based on the first number, and the length value of the reference block used for performing intra-frame coding on the entire real-time overhead picture in the horizontal direction is determined based on the second number, wherein the first number is a first multiple of the height value of the reference block used for performing intra-frame coding on the entire real-time overhead picture in the vertical direction determined based on the first number, and the second number is a second multiple of the length value of the reference block used for performing intra-frame coding on the entire real-time overhead picture, thereby realizing customization of the size of the coding block based on the imaging characteristics of the important components of the electronic meter.

[0005] Therefore, the present invention needs to have at least the following three important invention points: First, an electronic eye imager is used to take a bird's-eye view of the surface of the electronic meter to obtain and output a corresponding real-time bird's-eye view. This real-time bird's-eye view is then subjected to a nonlinear transformation using an exponential function, a morphological process using dilation followed by erosion, and distortion correction to obtain and output a more reliable end-point enhanced image. Second, parsing a surface imaging area in the received terminal enhanced image according to a standard contour pattern of the surface of the electronic meter, and outputting the number of pixel rows and the number of pixel columns occupied by the surface imaging area as a first number and a second number, respectively; The third part: determining the vertical height value of the reference block used for intra-frame encoding of the entire real-time overhead image based on the first quantity, and determining the horizontal length value of the reference block used for intra-frame encoding of the entire real-time overhead image based on the second quantity, wherein the first quantity is a first multiple of the vertical height value of the reference block used for intra-frame encoding of the entire real-time overhead image determined based on the first quantity, and the second quantity is a second multiple of the horizontal length value of the reference block used for intra-frame encoding of the entire real-time overhead image determined, thereby achieving customization of the size of the coding block based on the imaging characteristics of the important components of the electronic meter.

[0006] According to the present invention, there is provided an electronic electricity meter, comprising an electronic electricity meter body and a block size selection system for the electronic electricity meter, the system comprising: An electronic eye imager is used to perform a top-down shooting action on the surface environment of the electronic meter to obtain and output a corresponding real-time top-down picture; A head-end enhancement mechanism, connected to the electronic eye imager, is used to perform nonlinear transformation processing using an exponential function on the received real-time overhead image to obtain and output a corresponding head-end enhanced image; A secondary-end enhancement mechanism, connected to the primary-end enhancement mechanism, configured to perform a morphological process of dilation followed by erosion on the received primary-end enhanced picture to obtain and output a corresponding secondary-end enhanced picture; The end enhancement mechanism is used to perform distortion correction processing on the received secondary end enhanced picture to obtain and output the corresponding end enhanced picture; a content analysis device connected to the terminal enhancement mechanism, configured to analyze a surface imaging area in the received terminal enhancement image according to a standard contour pattern of the surface of the electronic meter, and output the number of pixel rows and the number of pixel columns occupied by the surface imaging area as a first number and a second number, respectively; A block identification device, connected to the content analysis device, is used to determine a vertical height value of a reference block used for performing intra-frame coding on the entire real-time overhead image based on the first quantity, and to determine a horizontal length value of the reference block used for performing intra-frame coding on the entire real-time overhead image based on the second quantity; Among them, determining the vertical height value of the reference block used for performing intra-frame coding on the entire real-time overhead image based on the first quantity, and determining the horizontal length value of the reference block used for performing intra-frame coding on the entire real-time overhead image based on the second quantity include: the first quantity is a first multiple of the vertical height value of the reference block used for performing intra-frame coding on the entire real-time overhead image determined based on the first quantity, and the second quantity is a second multiple of the horizontal length value of the reference block used for performing intra-frame coding on the entire real-time overhead image determined.

[0007] The block size selection system for electronic meters of the present invention has a compact design and wide application. By using an electronic eye imager to perform a bird's-eye image of the environment surrounding the electronic meter's surface to obtain and output a corresponding real-time bird's-eye view, and based on the optimized imaging data of the electronic meter's surface in the real-time bird's-eye view, a customized image processing scheme for performing intra-frame encoding on the entire real-time bird's-eye view is employed, thereby improving the effectiveness and efficiency of image processing.
