New technology of automatic meter verification instrument

Introduction: After installing the light source without a light source, the automatic indicator table vernier has a clearer and sharper image. This ensures that the readout value is more accurate, especially when the calibration dial is a convex indicator table, the non-reflective light source is well resolved. The contradiction between lighting and reflection has improved the reliability of data.

The appearance of the automatic meter verification instrument greatly facilitates the verification work. However, when the CCD completely simulates the reading value of the human eye, the light emitted from the ring light source is reflected at a position on the surface of the indicator sheet and enters the photographing lens. The surface image at this position is severely obscured by the intense light spots (or surfaces) of the light source, thereby forming interference, and a clear image of the indicator table cannot be obtained, which affects the detection result.

The patented lightless light source technology developed by Sinopharm Instruments has completely solved this problem. After the installation of the lightless light source, the captured image is clearly sharper and the readout value is more accurate, especially when the dial is a convex indicator table, the non-reflective light source solves the contradiction between illumination and reflection well and improves. The reliability of the data.

Light is closely related to our lives. Light also has a huge impact on our automatic calibrator. Automatic calibrator uses CCD to simulate the human eye to read the indicator, and the light emitted from the ring light source will A certain position on the surface of the indicating table is reflected and enters the shooting lens, so that the surface image of the position is severely obscured by a strong light spot (or surface) of the light source, thereby forming interference, and a clear image of the indicator table cannot be obtained, which affects the detection result. Our non-reflective light source was installed on the automatic meter verification instrument developed by the company in 2003. Our company has also become the first manufacturer in China that has a non-reflective light source technology automatic metering meter.

This technology has the following advantages:

1. High definition of image: It completely solves the problem of unclear image captured by CCD. The image captured with non-reflective light source has high definition, good picture quality, and image quality is an important basis for image recognition accuracy.

2. The value is more accurate: It can ensure that the readout value is more accurate, especially when the dial is a convex indicator table, the new light source solves the contradiction between illumination and reflection well, and improves the reliability of the data.

3. The structure is simple and convenient to operate.
