Paper Abstract

A 3-D coordinate measurement with novel concept and experimental arrangements of large space and multiple viewpoints is proposed. The measurement system includes a stereovision sensor and a separate LCD stripe projection. This measurement method ensures a high number of object points, up to 5x5x5m measurement volume, and rapid data acquisition. If only one and next partial view have an overlap area, system could automatically transform each partial views measuring data into a same world coordinate system. It can measure a wider area or 360 degree (whole-body) shape by alter the stripe projection's position. Furthermore, it is unnecessary to stick any marker on the object surface and a subsequent matching of the partial view is not required to obtain a whole-body measurement.
