We investigate a method to obtain accurate 3D measurements and we compare it with a standard photogrammetry method. The method utilizes a closed-loop to bring the point under measure in the middle of the two images of a stereo pair. It uses poor calibrated cameras and the accuracy of the measurements relies on the high resolution of the stereo head encoders and on its calibration as well. Experimental results have shown that the proposed method is more accurate than the standard photogrammetry method, as well as it is more robust to small variations of the initial position of the cameras
