The invention discloses an automatic water-meter detection system based on image processing. The system includes a water meter. The water meter is connected with a wireless camera module through a wireless network. The wireless camera module is connected with a main control chip. The system also includes a flow sensor. The flow sensor is connected with the main control chip. The main control chipis connected with a human-machine interaction system, and includes an algorithm migration module, a wireless communication module, a resetting module and a power supply module. The power supply moduleincludes a super capacitor and a battery. The invention also discloses a method of image processing. Firstly, a water-meter image is preprocessed by the algorithm migration module of the main controlchip, then a number reading area of water-meter data is accurately positioned, and characters of the positioned number reading area are divided into single characters, then 13-dimensional feature vectors are extracted and obtained, and finally, a neural network model is employed to carry out character recognition on the extracted 13-dimensional feature vectors to obtain a certain particular recognition number matrix. The detection system and the image processing method disclosed by the invention facilitate counting of the water-meter data and detection of the amount of used water.
Description
technical field [0001] The invention belongs to the technical field of intelligent control, and relates to a water meter automatic detection system based on image processing and an image processing method thereof. Background technique [0002] Water is an integral part of human beings, and everyone needs to use water resources. In areas with complex geographical environments such as rural areas and old urban houses, the traditional manual meter reading method not only consumes a lot of human resources and costs, but also may cause errors in the water meter data obtained by meter reading, resulting in waste of water resources and even It will also cause disputes between users and water companies. For water supply companies and users, the disadvantages of the traditional meter reading charging method are becoming more and more prominent, and the difficulty of meter reading charging has also become a problem in the management of water supply companies. Inapplicable and unecon...
