This study is aimed at developing a high-reliability motion stereo system through the consideration of camera vibration. In stereo measurement, we can approximate the distribution of measurement the error in images as a uniform distribution, and the distribution of the disparity error as a triangular distribution. Therefore, the parameters of the distributions are the mean value µ and the standard deviation σ, while the amplitude A and the frequency F are regarded as parameters of camera vibration. In our previous work, we constructed a model of the measurement error resulting from camera vibration. In this study, we define the existing probability of objects by using the measurement error model, and the reliability of object position. In addition, we verify the validity of the existing probability and reliability.
