Specific embodiment
To keep the purposes, technical schemes and advantages of the embodiment of the present application clearer, below with reference to drawings and examples,
The specific embodiment progress of technical scheme in further detail, is clearly illustrated.However, specific implementations described below
Mode and embodiment are for illustrative purposes only, rather than the limitation to the application.It only contains the implementation of the application a part
Example, instead of all the embodiments, the other embodiments that those skilled in the art obtain the various change of the application all belong to
In the range of the application protection.
Fig. 1 is a kind of composition schematic diagram for image recognition meter reading terminal that one embodiment of the application provides, including dress of taking pictures
Set 11, image processing apparatus 12, first transceiver 13.
The image of the shooting meter of camera arrangement 11.Image processing apparatus 12 determines the fringe region of image, according to pre- level pressure
Contraction ga(u)ge then carries out pixel compression to fringe region and generates compression image.First transceiver 13 send compression image to data platform into
Row image restoring and application.
Camera arrangement 11 is to provide the main modular for image of taking pictures for image recognition meter reading terminal, including but not limited to camera shooting
The components such as head, flash lamp, it can carry out control triggering by timing or manually, after camera arrangement 11 is triggered, dodge opening
Light lamp, and start camera, it takes pictures.
On the problem of taking pictures, the high camera of pixel is taken pictures clearly, but the data volume of image is big, is caused to data transmission
Pressure, and the low camera of pixel can preferably solve the problems, such as transmission, but the clarity of image is inadequate, be easy to cause use
Image recognition engine can not identify or identify difficulty, it is often more important that in terms of review, reviewing officer also differentiates unclear.
The camera arrangement 11 of the present embodiment can choose the camera for supporting highest 640*480 pixel image, can adjust
Whole output pixel size, by image recognition engine server verifying and function in terms of demand, such image can expire
The requirement of sufficient discrimination.
Image processing apparatus 12 uses a kind of image border compression method, when installing and using for the first time, passes through the first transmitting-receiving
Then the image of the transmission shooting of device 13 receives knowing by image from data platform by first transceiver 13 to data platform
The position of the size and main view for the image main view that other engine server determines in the picture determines therefrom that in image except main view
Fringe region except figure.In the later period in use, if image recognition meter reading terminal installation condition does not change, main view size and
The position of main view in the picture is also constant.
Fig. 2 is a kind of schematic diagram for image edge area that one embodiment of the application provides.As shown in Fig. 2, P1 is image,
P2 is main view.X is pixel distance of the image left edge to main view left edge, and y is image top edge to main view top edge
Pixel distance.The region of P1-P2 is fringe region.
Fringe region is compressed and is restored, is mainly manifested in as shown in Figure 3A, i.e., the matrix represented in (00, mn)
In, the data of even column in matrix are rejected, but do not reject the data that region shown in (ab, cd) includes.Obtained data
Matrix is content shown in Fig. 3 B.This process belongs to the compression process of image.
The compression image obtained after above-mentioned image procossing is sent to data platform 2 by first transceiver 13, number
It is sent to image recognition engine server 3 by image is compressed according to platform 2, pixel will be carried out in image recognition engine server 3
Reduction, this process belong to the reduction process of image.The compressing image data that image recognition engine server 3 will receive, according to
Predetermined reduced rule corresponding also meta-rule, the data of the even column really lost to it restore, and the method for reduction is by its left side
The data of side are replicated and are filled into even column, and the image finally restored is as shown in Figure 3 C, i.e. the data and the of 2i column
The data of 2i-1 column are identical.Specific compression of images and the method for reduction are not limited thereto.
By processing, the valid data amount of image will reduce one third.For first transceiver 13, the frequency of transmission
Rate will also reduce one third, to improve the success rate of data transmission, the use of flow also reduces one third, to subtract
Use cost is lacked.
This method is based on application scenarios, firstly, image recognition meter reading terminal does not taking cost into account include with image
The processing unit of Processing Algorithm does not have complicated image sampling function.Secondly, the operation that complicated image sampling function needs
Energy consumption can be allowed to increase, so simple image processing method can only be used.And in image meter reading scheme, the center of image itself
Domain, which is actually needed, clearly to be showed, and review is facilitated, and can be used as the region of meter registration evidence, i.e., is defined as this region
Main view P2, by this method treated image border, i.e. the region of (P1-P2) can cause a degree of distortion, but first
First the degree of its distortion has no effect on identification of the main view P2 of diagram in image recognition engine server 3, ensure that meter
The correctness that registration is read by image recognition, secondly, pixel shown in image border belongs to meter other information region, body
Show the information such as the dial plate appearance of meter, when manual review only confirms that it does not change to the review in this region, it is believed that with
It is same meter when installation, so reducing clarity caused by its distortion is approved in range in industrial application, i.e., not
Influence image recognition meter reading terminal use process in systems.
The technical solution that the present embodiment proposes is not influencing image recognition by being compressed and being restored to image border
In the case where success rate, reduce the data volume of data transmission, increases the knowledge of the success rate and image data in data transmission
Not rate.

It moves and alerts, the meter of terminal or terminal association may be disassembled, moves or be transformed, and administrative staff can be according to letter
Breath does corresponding processing.
Particularly, when vibration-sensing module 18 starts, sensed image identifies the vibration of meter reading terminal, to main control module 15
It sends a warning message, main control module 15 controls camera arrangement 11 and carries out upload of taking pictures, to record situation when alerting.
Particularly, when vibration-sensing module 18 is taken pictures using delay, it is to record vibration generation that delay, which is taken pictures,
The situation of adjoint generation afterwards, that is, when vibration-sensing module 18 starts, image recognition meter reading terminal and meter are thoughts
It answers, there are no being subjected to displacement or changing, delay is taken pictures, and is able to record a period of time after the starting of vibration-sensing module 18, is occurred
Situation.
Particularly, vibration-sensing module 18 start after take pictures for a period of time behavior time set, be rule of thumb
It is set, this time is too short or too long possibly can not all record truth at that time.
Wherein, alternatively, image processing apparatus 12 includes main view determining module 121, marginal zone
Domain determining module 122, compression module 123.It is specific same as the previously described embodiments.
Timing trigger module 17 includes clock, timer.Clock passes through main control module 15 and first transceiver 13 to data
Platform obtains clock information, according to the time of clock information synchronised clock.Timer receives the timing from main control module 15 and refers to
It enables, according to the parameter setting timing in time-of-the-day order.
The technical solution that the present embodiment proposes, by the addition of vibration-sensing module and information acquisition module, so that terminal
Image data can be transmitted correctly when change in location, and acquire more temperature, humidity, battery information, make terminal more intelligence
Energyization.
