Evaluation of three-dimensional measurement method based on phase shifting methods

摘要

We have developed three-dimensional shape measurement system. It is able to be used as security systems which protect properties and lives of people. This system uses phase shifting method measuring three-dimensional shapes. The traditional phase shifting method requires projecting several patterns on a target, and it needs high processing cost to solve phase unwrapping problems. So the traditional phase shifting method is hard to work in real time. Our method projects only one pattern on a target and needs low processing cost.
