Estimation of the measurement error of photogrammetric techniques by controlled flexible deformable surface

The paper describes developed optoelectronic system for estimating of the measurement error of photogrammetric techniques. The idea of this system based on comparison of the results obtained with tested techniques with the results obtained by precise sensor, which allows determining the absolute measurement error of the techniques within the error of the sensor. As reference surface to measure the special developed device was used. As a test photogrammetric technique the Image Pattern Correlation Technique was used. The paper contains main information about developed system, its technical characteristics, detailed description of the system software and examples of experimental results obtained by the system.
