| Summary: | Every measurement performed must have an error, one of them is derived from the inside of instrument used. This error usually called as systematical error. In order to minimize the effects of systematical error, some calibration can applied to the instrument. In this research, the instrument will be calibrated is Terrestrial Laser Scanner (TLS). Since TLS is an instrument within new technology, there is no standardized method of TLS calibration. According to Optical Test and Calibration Ltd, calibration is the activity of checking, by comparison with a standard, the accuracy of a measuring instrument of any type. So, in this reaserch, the calibration will be carried out is by comparing the measurement results of TLS with the measurement results of ETS which is has a true measurement results. In the process of its implementation, the calibration is performed in a room that has been set targets that will become the object of measurement. Data acquisition with TLS is started by scanning the target and followed by scanning the room. The acquisition of data with the ETS is only done by measure the existing target. The results from these two data acquisition are then processed to obtain the data to be compared, i.e. the data range and target coordinates result. The difference between the results of the comparison shall be considered as the value of the measurement error of the TLS. From this research, the average value of distance differences is 4 mm and the average value of targets coordinate differences are -4 mm on e-axis (easting), -2 mm on n-axis (northing), and -3.2 m on u-axis (up). |
