A factory calibration method of IoT water meter based on image recognition |
| abstract |
The invention discloses a method for factory calibration of an Internet of Things water meter based on image recognition. The image recognition algorithm is used to calibrate the Internet of Things water meter before leaving the factory. The method first obtains the meter number of the Internet of Things water meter; then collects the dial image of the Internet of Things water meter; The dial image is processed, and the blocks containing only the dial are cut out; then the image recognition of the blocks containing the dial is performed to obtain the water meter reading; finally, the meter calibration device establishes a connection with the server, and uploads the IoT water meter number and water meter reading to the server. , complete the IoT water meter calibration. The invention reduces the workload of the Internet of Things water meter calibration personnel and improves the meter inspection efficiency; and the Internet of Things water meter calibration method of the invention has a high degree of automation, simple operation and high accuracy. |
