CAM-OCR Camera module

Module 'CAM - OCR' is designed for scanning of seven-segment display through a computer provided with the digital camera. 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 software processes the image information, transferring it into the digital ASCII code.

The camera may be connected to the computer without a necessity of switching off. It is completely functional upon connecting to the USB-port (after the installation of the program). The supplying is ensured also from the USB-port. The module requires no auxiliary lightning, however, under poor light conditions, an image evaluation may last longer.

Read-Cam software

Program module 'ReadCam' intended for processing of measuring results without support of WinQbase. Values taken from the display are written directly into the file '*.xls' for further processing in the Excel software. The program is suitable for the checking of measuring instruments. It enables an elaboration of multiple measurements, calculation of the value dispersion as well as measurement uncertainty.

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.
