Stereo vision-based measurements device for construction inspection

A measurement device for fast dimensional inspection in construction industry is designed and developed based on stereo vision. Two high-resolution cameras based on 13MP image sensor are used in this device. A variety of invariant detectors and descripters are used for image matching. The measurement error for 200 mm baseline is less than 1 mm within a range of 5 m. A prototype has been developed and tested in real construction sites.
