Acquiring even striped patterns intensity in three-dimensional shape measurement system using an optical modulator

摘要

We have continued research on our three-dimensional shape measurement system, using spatial projections of light variation patterns. This method is non-contact, non-invasive, and completes measurement in a short time. However, light diffusion influence on the measurable accuracy. We proposed a method using differentiation to enhance accuracy of measurement, and were successful in achieving this goal. Moreover, the measurable area was expanded. Since our method involves computational manipulation of the data obtained by the original system, it requires no additional equipment. It is a very practical and effective method.
