Embodiment Construction

[0041] 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. However, due to the diversity of the camera direct reading meter reading device 10 and the base meter installation environment, especially when the environment is relatively harsh, the camera directly reads the meter reading device 10. 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 ...

Abstract

The invention discloses an image pickup direct meter reading device and system and a method and a device for increasing image pickup direct meter reading identification rate. During installation of the image pickup direct meter reading device, a testing device performs the following steps: acquiring different shooting parameter signals in sequence, and transmitting the shooting parameter signals to the image pickup direct meter reading device; receiving image signals shot by the image pickup direct meter reading device at different shooting parameters, and displaying the received image signals; receiving an image frame having best image quality selected by a user, wherein a shooting parameter corresponding to the selected image frame is a finally-set shooting parameter; and transmitting the finally-set shooting parameter to the image pickup direct meter reading device in order that the image pickup direct meter reading device saves the finally-set shooting parameter, and working at the finally-set shooting parameter. Through implementation of the technical scheme of the invention, the image pickup direct meter reading device can adapt to an installation environment, a shot image has high image quality, and the image pickup direct meter reading identification rate is increased.

Description

technical field [0001] The invention relates to the field of meter reading, in particular to a camera direct reading meter reading device, a system, a method and a device for improving the recognition rate of camera direct reading meter reading. Background technique [0002] The remote meter reading system for water, electricity and gas meters has been developed for decades, but the technical difficulty is still how to provide the accuracy of the readings. The inherent advantages of the camera direct reading meter reading system are convenient installation, long service life, strong anti-interference ability, and strong traceability of information. However, the camera direct reading technology relies on software algorithms to recognize the numbers on the photos, and the recognition is accurate. Speed ​​is one of the biggest obstacles to current application. If its recognition rate is not high, it will not be able to achieve the effect of the remote meter reading system at a...
