Embodiment Construction
[0043] combine figure 1 , in the camera direct-reading meter reading system, during normal operation, the camera direct-reading meter reading device 10 photographs the readings on the base meter surface, and the generated image signal is transmitted to the far end, so that there is no need to manually arrive at the scene to carry out meter reading. In addition, the camera direct reading meter reading device 10 generally sets its shooting parameters to default values when it leaves the factory. The quality of the image taken by the meter reading device 10 is not high, and the base meter reading cannot be clearly identified after the image is transmitted to the remote end. In order to improve the camera direct reading meter reading recognition rate, it is necessary to arrange a test device 20, use this test device 20 to adjust its shooting parameters when the camera direct reading meter reading device 10 is installed, to adapt to the installation environment on the spot, so t...
