Embodiment Construction

[0054] Such as figure 1 As shown, a camera meter reading system based on deep learning includes: a camera stand, a smart meter reading terminal and a radio frequency module; the smart meter reading terminal and the camera stand are connected wirelessly through a radio frequency module.

[0055] The camera frame includes a supplementary light LED system, a macro camera and an MCU. The supplementary light LED system is fixed on the sides of the four sides of the camera frame, the macro camera is located at the top of the camera frame, and the MCU is installed on the macro camera. The MCU and the smart meter reading terminal are each connected to a high-performance RF transceiver; the RF transceiver enters the RF range to start wireless communication, and sends an interrupt request to the MCU. The captured image is sent back to the smart meter reading terminal. The smart meter reading terminal divides the dial wheel and the small dial and uses the 0-9 feature vector obtained from...

Abstract

The invention discloses a camera shooting meter reading system and method based on deep learning. The system comprises a camera frame, a smart meter reading terminal and a radio frequency module; thesmart meter reading terminal and the camera frame are wirelessly connected through the radio frequency module; a radio frequency transceiver enters a radio frequency range to start wireless communication and to send an interrupt request to an MCU, the MCU activates a fill light system, an acceleration sensor and a macro camera successively for working, the camera transmits a shot image back to a raspberry pie carried on a smart terminal, the raspberry pie splits a dial plate character wheel and a small dial plate to perform sample model training so as to obtain feature vectors of 0-9, then processes the collected dial plate images, and obtains the actual reading of the dial plate of a water meter. In the camera shooting meter reading system and method disclosed by the invention, the recognition accuracy of the dial plate of the water meter is high, the accuracy is high, the communication cost is low and the stability of data transmission is high.

Description

technical field [0001] The invention relates to the technical field of camera intelligent meter reading, in particular to a camera meter reading system and method based on deep learning. Background technique [0002] Camera meter reading usually includes camera direct reading meter reading, remote camera meter reading and wireless camera meter reading methods. At present, the field of camera meter reading has been widely concerned by scholars at home and abroad. For example, [Design of the Wireless Remote Water-Meter-Reading System Based on Meter-Dial Photography] proposes a wireless water meter applied to the remote CC system. The amount is too large, the communication cost is high, and the transmission rate is slow. [0003] In the prior art, many methods have been proposed to solve the shortcomings of manual meter reading errors, omissions, estimation and copying. Chinese patent CN 201331354Y, published on October 21, 2009, application number 200920104941.4, camera dir...
