Paper Abstract

Three pulsed time-of--flight laser rangefinders have been developed for studying the measurement of the 3-D shape of large objects. A manually scanned system is suggested for manufacturing accuracy measurement and control for ship block assembly. This system can be used to measure distance, plane regularity, angles, spatial forms etc . , within a range from 3 m to 30 m with mm-level accuracy . The two others are automatically scanning based on galvanometer driven mirrors, and a servo-controlled mechanical scanner. These systems are intended for applications where it is important to be able to gather 3-D data automatically and with high speed. The resolutions are also on the mm-level, but the measurement speed is 10 000 points/s at maximum.
