New method for three-dimensional measurement by using the relative stereo method

Abstract

In recent years, three-dimensional measurement in machine vision is applied to various places, such as a production line. When applying to a production line, in order to raise its reliability and cost performance, it is indispensable to measure the three-dimensional position of an object at high speed and with high precision. Then, in order to measure the position of an object, we propose the new three-dimensional measurement technique which combined the single light stripe method and the relative stereo method in this paper. Further, we will show that this technique can measure the three-dimensional position of all the objects projected in the stereo images at high speed and with high precision. Finally, we show results of an evaluation experiment for the measurement technique.
