要約(英語): Phase Shifting Method, measuring method of three-dimensional shapes, is able to measure by high accuracy in short time. However there are some difficulties to acquire three-dimensional data because of phase unwrapping problem which occurs phase unwrapping errors and makes accuracy worse. Some of techniques have been used for avoiding the problem in the traditional methods. One of the traditional methods combines with space encoding method. This method could be robust and high accurate but requires several gray-code patterns other than phase shifting patterns. This makes measuring time longer. In this paper, we propose a correcting phase unwrapping error method which requires only phase shifting patterns to measure objects. The proposal method corrects over 99 [%] phase unwrapping errors. This result is almost same as the result of the traditional method. Therefore we are able to unwrap phase values as same accuracy as the traditional method by our proposal method despite reducing projecting patterns.
