The system consists of a handheld laser scanning sensor and a position sensor. The laser scanning sensor is used to acquire the surface and geometry information, and the position sensor is utilized to unify the scanning sensors into a global coordinate system. The measurement process includes data collection, multi-sensor data fusion and surface reconstruction. With the multi-sensor data fusion, errors accumulated during the image alignment and registration process are minimized, and the measuring precision is significantly improved. After the dense accurate acquisition of the three-dimensional (3-D) coordinates, the surface is reconstructed using a commercial software piece, based on the Non-Uniform Rational B-Splines (NURBS) surface. The system has been evaluated, both qualitatively and quantitatively, using reference measurements provided by a commercial laser scanning sensor. The method has been applied for the reconstruction of a large gear rim and the accuracy is up to 0.0963 mm. The results prove that this new combined method is promising for measuring and reconstructing the large-scale objects with complex surface geometry. Compared with reported methods of large-scale shape measurement, it owns high freedom in motion, high precision and high measurement speed in a wide measurement range.     <\/jats:p>","DOI":"10.3390\/s150614328","type":"journal-article","created":{"date-parts":[[2015,6,17]],"date-time":"2015-06-17T11:19:34Z","timestamp":1434539974000},"page":"14328-14344","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Fast Measurement and Reconstruction of Large Workpieces with Freeform Surfaces by Combining Local Scanning and Global Position Data"],"prefix":"10.3390","volume":"15","author":[{"given":"Zhe","family":"Chen","sequence":"first","affiliation":[{"name":"State Key Lab of Precision Measuring Technology and Instruments, Tianjin University, Tianjin 300072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fumin","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Lab of Precision Measuring Technology and Instruments, Tianjin University, Tianjin 300072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xinghua","family":"Qu","sequence":"additional","affiliation":[{"name":"State Key Lab of Precision Measuring Technology and Instruments, Tianjin University, Tianjin 300072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Baoqiu","family":"Liang","sequence":"additional","affiliation":[{"name":"State Key Lab of Precision Measuring Technology and Instruments, Tianjin University, Tianjin 300072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2015,6,17]]},"reference":[{"key":"ref_1","unstructured":"John, M., Allan, S., Manhtriet, H., and Arnold, F.
