Abstract/ Foreword

Due to usage, handling, and improper storage, measuring tapes undergo changes in their condition over time. For this reason, regular inspection is necessary to ensure the desired quality of results, aiming to verify the accuracy of the tape and its usability in practice. During the calibration of measuring tapes, the position of the scale divisions on the tape is evaluated using a device known as a horizontal comparator. This device consists of a linear base on which a carriage with evaluating equipment, in our case a camera, is automatically moved. The position of the carriage movement is measured by laser interferometer. To eliminate the very laborious and time-consuming precise positioning of the camera over the division on the scale, the position of the division relative to the camera's projection centre is evaluated by processing the image of the calibrated tape. The article describes this novel solution and the device developed for this purpose. Using the developed comparator, calibration of tapes and other length measures, such as levelling staffs could be done. The entire calibration process is autonomous, thanks the user interface developed for the calibration process. Second part of the article focuses on the analysis of results and their comparison with another laboratory.
