Unrelated information, restores useful real information as in, enhances detectability for information about and simplifies data to the maximum extent,
So as to improve feature extraction, image segmentation, matching and the reliability of identification.
In another embodiment, image preprocessing further includes, and amr message sample image is normalized.For example,
The dial plate image of a variety of different amr messages is collected, after creating amr message sample image, by all establishment amr message samples
This image is all normalized into 240x240 sizes, then extracts the characteristic of amr message sample image.In this way by uniformly copying
The size of table message sample image is convenient subsequently to be established detection model and realizes detection to amr message.
S330 carries out pattern-recognition training to the characteristic of all amr message sample images, obtains amr message inspection
Survey model.
Specifically, amr message detection model may be based on the detection model of grader structure, by believing all meter readings
The characteristic for ceasing sample image carries out pattern-recognition training, and the dial plate image of variety classes, different representations is divided
Class, based on every a kind of establishment amr message detection model.
Wherein, grader can be k nearest neighbor grader, decision tree classifier and support vector machine ensembles learning method etc., no
With grader is divided to have different pattern-recognition training algorithms, user can be based on recognition accuracy, recognition efficiency selects difference
Grader structure amr message detection model.
By obtaining the dial plate image of a variety of different amr messages, sufficient amr message sample image is ensure that, into one
Step extracts the characteristic of all amr message sample images, and pattern is carried out to the characteristic of all amr message sample images
Recognition training and classification, so as to obtain a variety of inhomogeneous amr message detection models, to meet the knowledge to different amr messages
Other demand can further improve the accuracy rate of amr message identification.
In another specific embodiment, amr message further includes User ID and continuous data, when gauge table ID databases
During including detecting obtained gauge table ID, obtain amr message and the step of export after, further include：By User ID, gauge table
ID and continuous data associated storage.Wherein, each gauge table has unique corresponding gauge table ID.
By by User ID, gauge table ID and continuous data associated storage, fully integrating the related data of each gauge table,
To realize that meter data is shared and provides strong data supporting, convenient for the continuous data of each gauge table is carried out statistics and
Management, and corresponding continuous data is inquired by User ID or gauge table ID fast and easys, it is obtained and the use convenient for user
The relevant continuous data in family.
Further, as shown in figure 4, automatic meter reading method further includes step S410 to step S430：
S410 according to continuous data, obtains metering data.
Specifically, according to acquired continuous data, corresponding expense can be calculated using charging algorithmic tool, convenient for root
It is deducted fees or is paid the fees according to the expense of gained.
S420 according to continuous data and metering data, generates metrical information.
