This study aims to establish a Robust sensor system by considering a camera vibration. In stereo measurement, we cam approximate the distribution of the measurement error in image by using uniform distribution. Therefore, the parameters of the distribution of the measurement error 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 relationships between the parameters with regard to the distribution of the measurement error and the parameters of the camera vibration, we performed an experiment using a vibration testing system. By the result, we can establish the measurement error model. Moreover, we defined the existing probability of the object by using the parameters of the measurement error. Additionally, in order to be minimized the errors, we proposed a variable baseline method. We verified effect of the variable baseline method.
