Embodiment 1

[0043] Such as figure 1 As shown, according to an embodiment of the present invention, the automatic water meter reading system based on image processing technology disclosed in this embodiment includes: a water meter image acquisition module that collects digital image information on the surface of the water meter through a camera , Send the image information to the image transmission module; specifically, install a module with a camera that can be powered by mains or lithium batteries on the top of the water meter, the camera is aimed at the surface of the water meter, and the shooting results can be transmitted to the image transmission module .

[0044] The image transmission module is used to compress the image and mark the collected image information, and transmit the processed image data to the cloud server through GPRS or WIFI network; the cloud server is used to receive all the data transmitted from each water meter The image data is described and stored according to ta...

Embodiment 2

[0047] According to another embodiment of the present invention, this embodiment discloses an automatic meter reading method for water meters based on image processing technology. Specifically, the method includes the following steps:

[0048] Step1, add the meter cover with the water meter image acquisition module and camera to the mechanical water meter, and the camera is aligned with the dial, which can be powered by mains or built-in lithium battery.

[0049] Step2: After the smart water meter control system sends out the meter reading instruction, the water meter image acquisition module performs an image acquisition on the dial.

[0050] Step3: After the image acquisition is completed, it is compressed by the image transmission module, marked and uploaded to the cloud server.

[0051] Step4: After the cloud server receives the picture, it is classified and stored according to the image tag. The purpose of classification is to match the data source at a faster speed after the reco...
