Abstract: In the 3D digital measurement of large-scale objects, image
mosaic is the key technology to achieve the whole measurement for the
small measuring field of sensor unit. The
mobile-coordination-measuring-systems-based three-dimensional image
mosaic technology is proposed. It has good flexibility and
manoeuvrability, and also can expand the measuring space to meet the
needs. Through experiments, the method is proven to be with relative
high precision on three-dimensional image mosaic and space length
measuring error is less than 0.091%.
Key words: Digital measurement Image mosaic Mobile coordinate measuring
