Abstract

The invention relates to a visual recognition-based power meter type detection method. The method comprises steps: (1) an image acquisition device is used for photographing a power meter to acquire a power meter appearance image; (2) an image pre-treatment device is used for carrying out pre-treatment on the power meter appearance image to output a pre-treatment appearance image; and (3) based on various reference power meter patterns pre-stored in a static storage device, a Freescale IMX6 treatment device carries out one-by-one matching on the pre-treatment appearance image, and the type of a reference power meter pattern succeeding in matching is outputted to serve as a target power meter type. Thus, accurate reference data can be provided for a power supply department, and important basis is provided for monitoring on the power meter by the power supply department.

Embodiment Construction

[0046] The implementation of the detection system implementing the visual recognition-based electric energy meter model detection method of the present invention will be described in detail below with reference to the accompanying drawings.

[0047] An electric energy meter is an instrument used to measure electric energy, also known as an electric watt-hour meter, a fire meter, and a kilowatt-hour meter.

[0048] The working principle of the electric energy meter is as follows: when the electric energy meter is connected to the circuit under test, an alternating current flows in the current coil and the voltage coil, and the two alternating currents generate alternating magnetic flux in their iron cores respectively. The alternating magnetic flux passes through the aluminum disc and induces an eddy current in the aluminum disc; the eddy current is subjected to force in the magnetic field, so that the aluminum disc obtains torque (active torque) and rotates. The greater the po...
