This paper describes recent trends in three-dimensional shape measurement technologies and multi-spectral image capture and processing. Two types of rangefinder, triangulation method and time-of-flight method, have been developed in wide application fields, for example, generation of database of human body, archives of remains and ruins, security monitoring, etc.. Their response time and accuracy have been improved sufficiently for practical applications. Spectral imaging technique has attracted attention in the machine vision field to enhance measurement and inspection systems. This paper also describes color analysis techniques using an imaging spectrograph for acquiring multi spectral image in real-time.
