Effects and Correction of Camera Shaking in Stereo Measurement
The measurement error influenced by the camera tiny shaking including translation, rotation and the combination in the stereo measurement are analyzed. The correction method of camera shaking based on the theory of photogrammetry is proposed, using control points in scene and the measurement error by calculating the camera pose with corrected pose estimation. Simulation results show that, with the tiny shaking, the camera translation makes the measurement errors increase linearly, while the rotation makes the errors grow quadratically. The re-projection error in the object space is less than 1 mm with short distance measurement and proper arrangement of four control points, and it gradually falls below 0.55 mm with the increase of control points number. Simulation experiment verifies the reliability of the correction method, and this method can be used in stereo measurement on an unstable platform to reduce the effect of camera shake.
