Wherein, meter reading terminal includes: the camera and the wireless transmission module can shoot a picture to be read, upload data to the meter reading platform through the wireless module and receive configuration issued by the meter reading platform; the configuration here may include: the shooting times, the shooting intervals, the characteristic values of the target photos and the like;
the meter reading platform mainly has the functions of receiving the photos uploaded by the terminal, selecting the characteristics of the target screen photos, selecting the target screen photos, displaying the recognition results and interacting with the terminal through issuing configuration.
The meter reading expert system mainly has the following three characteristics: the terminal is combined with a cloud end of platform interaction; a library of algorithms for different phenotypes, different characteristics; the terminal has edge computing capability; the meter reading expert system is introduced below by combining the three characteristics.
In the embodiment of the invention, the terminal takes a group of photos according to a certain number of times of taking photos and a certain photo interval, so as to ensure that the group of photos includes each screen of the multi-screen meter, generally, the number of times of taking photos and the photo interval cover a jump cycle (that is, the multi-screen meter starts from one screen and is switched to the screen again), and the group of photos are uploaded to the meter reading platform;

after receiving the characteristic value issued by the platform, the terminal can select to take multiple groups of pictures each time and upload the pictures to the platform, and the platform selects a target picture, or only upload the target picture after the terminal selects the target picture.
Based on the interaction mode, a series of functions of photographing, uploading, feature selection and feature identification can be realized.
The target screen selection method based on feature recognition and the description of the algorithm library are as follows:
the target screen selection based on the feature recognition is to use an image recognition technology to distinguish different features of the same or multiple feature positions of different screens and select a photo desired to be displayed by a client.
As shown in fig. 2, the characteristic area of a group of photographs (including three photographs) is a box portion, and the different screens are distinguished by three lamps illuminated with the letters A, B, C. Therefore, it is sufficient to determine whether or not the corresponding lamp is turned on by the image recognition technology. The lighting position is judged by taking two methods of a color histogram and the number of black pixels as examples.
The color histogram is an RGB color space or a gray scale space, and takes a value of 0 to 255 correspondingly, and the horizontal axis is taken as the horizontal axis, and the vertical axis is the number of pixel points with corresponding values in the coordinate range of the selected picture. The feature value of the area can be expressed by a vector a = (A0, A1, A2, …, ai, …, a 255), and Ai represents the number of pixels in the area corresponding to the color space value i. The A may be used as a feature vector to determine whether the area is in accordance with expectations, and may be a color histogram (RGB) or a gray histogram, and the on/off of the lamp may be determined by the difference of the histograms when the lamp is on or off.
As shown in fig. 3, the number of black pixels is changed into a binary image by performing graying and binarization processing on the image, and the number of black pixels in the image is determined to distinguish whether the lamp is on or off, and the next image is a processing result of the lamp a and the lamp B, C after graying and binarization when the lamp a is on:
in fig. 3, the black pixel of lamp a is approximately: 950; the B lamp black pixel is approximately: 1400; the C lamp black pixel is approximately: 1440; a was judged to be different from B, C.
The meter reading platform stores different algorithms for different feature identification, the feature is identified by adapting to a proper feature identification algorithm based on the selection of the feature, and the identification algorithm can be optimized according to the feedback of the identification result. The feature recognition algorithm corresponds to different feature information, including but not limited to methods such as "color histogram", "black pixel" and the like mentioned herein, and some basic image processing methods (graying, binarization, expansion, corrosion and the like); the matching of the features to be recognized and the feature recognition algorithm can be dynamically adjusted according to the feedback of the recognition result, the consumed computation amount is limited, and the method can be operated in a meter reading terminal with limited resources;
as shown in fig. 4 and 5, the selection interface for meter reading platform features is shown, in the feature selection interface in the above figure, several keywords, i.e. objects, actions, and features, may be used to describe the difference between one target screen and other screens.
The JSON format can be used to describe the following:
{
object: { characters, lamps }
The actions are as follows: { Presence/absence, opening/closing }
Is characterized in that:
{
the text content is as follows: { "Total" }
Color: { black > 30%, yellow ≦ 30% }
Shape: { circle, line }
}
}
In particular to the example, the lamp can be simply described as:
{
object: lamp with a light source
The actions are as follows: open and close
Is characterized in that:
{
color: yellow colour
Shape: round (T-shaped)
}
}
According to the selected characteristics, the corresponding algorithm can be selected to select the photos, and the characteristic value of the algorithm is issued to the terminal, so that the terminal can select the target photos at the edge side based on the characteristic value and the algorithm.
The embodiment of the invention can also carry out interaction through a wireless transmission technology, the meter reading terminal receives the characteristic value, the shooting times and the shooting interval which are issued by the meter reading platform, selects a locally selected target photo or a group of photos to upload, and the meter reading platform dynamically adjusts and optimizes the characteristic value and the characteristic recognition algorithm according to the target photo uploaded by the meter reading terminal; the multi-screen ammeter reading terminal is used for multi-screen ammeter reading in the system, but the terminal has certain edge computing capacity, the platform performs feature recognition, and an expert system of terminal cloud interaction is not limited to the terminal, and the system can also be used for other platforms to select or recognize features based on data acquired by the terminal, and an algorithm can be operated in the application of the terminal.
The embodiment of the invention aims at the multi-screen multi-display electric meter without data transmission capability, and the meter reading can be realized by installing the terminal on the electric meter without any modification on the existing multi-screen electric meter to be read. Compare the ammeter that self possesses the long-range ability of uploading of data or through the scheme that infrared reading ammeter reading uploaded, instant photo to backstage of this scheme shooting ammeter, data credibility is higher.
In addition, the scheme can realize adaptation to different phenotypes and different characteristics, and meanwhile, based on edge computing capability of end cloud combination, transmission power consumption can be reduced, so that the cost of equipment is reduced.
