Camera shooting type remote water meter reading system achieving fast recognition and reading recognition method thereof

Abstract

Provided are a camera shooting type remote water meter reading system achieving fast recognition and a reading recognition method thereof. The system comprises a camera, a fill light, a single-chip microcomputer, a storage and an RS485 circuit; the camera is arranged to be just opposite to a dial plate of a direct-reading character wheel water meter, the fill light is arranged near the camera, light is emitted to the dial plate of the direct-reading character wheel water meter, the single-chip microcomputer is connected with the camera, the fill light, the storage and the RS485 circuit separately, image information of the dial plate of the direct-reading character wheel water meter is shot by the camera and sent to the single-chip microcomputer, the single-chip microcomputer firstly trains dial plate image training samples to obtain feature vector matrices of numbers from 0 to 9 and form a factor matrix, then the collected dial plate image information is processed to obtain digital pictures of all character wheels, and finally an actual reading of the water meter dial plate is obtained by multiplying the digital picture of each character wheel by the factor matrix. According to the camera shooting type remote water meter reading system achieving fast recognition and the reading recognition method thereof, the problem that an existing water meter reading system single-chip microcomputer is out of memory can be effectively solved, and the cost of the water meter reading system is lowered.

Description

technical field [0001] The invention relates to a water meter remote transmission system, in particular to a fast-recognition camera-type remote transmission water meter meter reading system and a reading recognition method thereof. Background technique [0002] my country's remote water meters can be roughly divided into two categories: pulse type and direct-reading type according to the collection method of data terminals. The development of the two types of water meters is gradually becoming mature, each occupying a part of the market share, and has formed certain applications in the industry. Norms are also widely accepted. Its principles and characteristics are summarized as follows: [0003] 1 pulse remote water meter [0004] The pulse-type remote water meter reading system has been developed for more than 20 years in our country, and the development and application of technology have reached a mature stage. The disadvantage of this type of water meter is that when ...
