Scales bar calibration for photogrammetric use
Calibration is done in our calibration room. The calibration wall used holds multiple photogrmmetric targets, and a standard carbon scale bar (Sn: CSB-40-2500-009).
Calibration is done with V-STARS S8 photogrammetric system. The standard carbon scale bar is calibrated each year by an authorized COFRAC laboratory (LNE, CETE, etc...)
The calibration room temperature is maintained at 20°C ± 1°C.
