Abstract
Several types of accurate and high-speed 3D shape measurement using
linear LED devices were developed by author's research group. The linear LED
device is a key device to develop them. High-speed phase shift synchronized with
camera triggers can be achieved by switching the lighting position of the linear
LED. The control signals can be generated easily with a no special micro-computer.
A compact projector unit can be produced. Author also proposed a calibration
method, named a whole-space tabulation method (WSTM), for an accurate and
high-speed shape measurement using multiple reference planes. A handy, fullcolor and real-time 3D shape measurement unit was developed using them A quick
3D shape measurement projection mapping system was also developed using them.
The measurement result and the evaluation value can be projected onto the
measured object just after 3D shape measurement. An accurate and vibrationresistant 3D shape measurement unit was also developed. This method, named a
feature quantity type whole-space tabulation method (F-WSTM), makes possible
a vibration-resistant 3D shape measurement. Three phase information obtained
with three projectors are used to obtain 3D coordinates without any camera
parameters. In this talk, these methods and the developed 3D shape measurement
units are introduced.
