This paper proposes a new multiviewpoint stereo measurement method. Accuracy is improved by integrating stereo data obtained from multiviewpoints whose relative positions are known. In this method, a normal distribution is assumed for the measurement error on the stereo image planes. First, th probability density functions of the measurement error from the multiviewpoints are combined. Then, the combined function is expressed using real space coordinates and coordinate transformation parameters which give relative viewpoint positions, and the most likely coordinates are estimated from the condition that minimizes the function. The variance in the estimated coordinates is analyzed. As a result, the optimum viewpoint positions for minimizing the measurement error are investigated, and the relationship between the number of viewpoints and variance of the optimum viewpoint positions are calculated. Finally, these results are confirmed by computer simulation.
