CamOcr camera module

CamOcr camera module extends possibilities of MEATEST automatic calibration software Caliber. CamOcr is designed for scanning of seven-segment digital displays of measuring instruments – devices under test.
Using CamOcr can be “connected” to the computer also instruments (UUT) that are not equipped with any kind of PC interface. UUT display is scanned by digital camera. CamOcr converts scanned pictures to numbers. These numbers (measuring results) are used in for further calculations. It is very easy to do repeated measurements and calculate uncertainty type A for every calibration point.
The module assembly incorporates a camera with the rotary holder retaining the camera attached to the pedestal, enabling the camera to be turned in several directions, setting in that way the optimal light conditions. The module requires no auxiliary lightning, however, under poor light conditions, an image evaluation may last longer.

Caliber / WinQbase software

Camera module is fully compatible with calibration software WinQbase. WinQbase serves for the registration and calibration of measuring instruments. With the camera-scanning module, it features entirely automatic calibration of digital instruments, which have no option to be connected to the computer. During the calibration process, the program proceeds similarly as if having been connected to the computer. The camera-scanned image is digitally processed and transferred into a digital information. The program is determined for seven-segment display. A set of measurements in each check point is done, then being statistically evaluated and deviation and uncertainty of measurement is stated. This solution benefits from a significant reducing of work quantity for calibration as well as from better repetition and objectivity of measuring. The system entirely eliminates influence of the operator on the uncertainty calibration.

CamOcr module can be used only as an option of Caliber software. Independent application is not supported.
