Abstract

This study aims to establish an error model for a stereo measurement system by considering camera vibration. In stereo measurements, we can approximate the measurement error distribution in images as a uniform distribution. Therefore, the parameters of the measurement error distribution are the mean value µ and the standard deviation σ, while the amplitude A and the frequency F are regarded as the parameters of the camera vibration. In order to verify the relationships between the parameters of the measurement error distribution and those of the camera vibration, we performed an experiment using a vibration-testing system. The results of the experiment showed that the vibration did not affect µ. Moreover, we found a positive correlation between σ and A as well as a negative correlation betweenσ and F. Using these relationships, we estimated the parameters of the measurement error from the parameters of the camera vibration.
