Embodiment Construction

[0049] The method for automatic recognition of the digital remote transmission image of the traffic meter can be implemented according to the following steps:

[0050] 1) Image preprocessing;

[0051] 2) character positioning;

[0052] 3) Image refinement;

[0053] 4) feature extraction;

[0054] 5) Character recognition.

[0055] Wherein, step 1) includes performing noise reduction and segmentation processing on the collected original reading image, the template filter method can be used to remove the noise in the image, and the adaptive threshold method is used to binarize the image at the same time; step 2) can be Multiple projection method is used to locate the position of each number in the meter image; step 3) adopts thinning algorithm to obtain single-pixel wide number body; step 4) adopts geometric feature extraction method to extract corresponding features; Geometric features include threading features, voyage features and point features; the step 5) uses a multi-fe...

Abstract

A method for identifying digital telemetering image of flow rate charging meter includes preprocessing image, positioning characters, detailing image, picking up characteristics and identifying characters. The digital telemetering-copying system of flow rate charging meter is also disclosed.

Description

technical field [0001] The invention belongs to the technical field of number automatic identification, and in particular relates to a method for automatic identification of digital remote transmission images of flow meter and a digital remote transmission meter reading system matched with the method. Background technique [0002] Since the reform and opening up, my country's urban population has increased dramatically. With the rapid expansion of the scale of residential construction, the installation of water meters and gas meters has also increased significantly. This leads to the following questions: [0003] (1) In recent years, the residential floors are generally higher than before the reform and opening up, and the labor intensity of meter reading personnel has increased significantly; [0004] (2) Residents spend significantly less time at home than before the reform and opening up, resulting in frequent occurrences of no one at home during meter reading, and some...
