设计并实现了一种融合线结构光、立体视觉以及数据处理的实物数字化系统。以自定位方式取代传统的机械结构解决测量装置位姿确定问题，进而实现多视角测量数据拼合。系统的测量装置由结构光子系统和立体视觉子系统2部分组成，结构光子系统负责实时重构单视角测量数据，而立体视觉子系统负责实时对齐融合多视角测量数据。由于系统的自定位特性，在测量过程中工件可以任意移动而不影响数据多视角数据融合结果。实验结果表明，该实物数字化系统测头定位精度优于0．05 mm，而整体扫描精度优于0．12 mm，扫描速度为10000点/秒，能够应用于工业现场进行复杂工件及模型、模具表面数据检测及模型重构。

An original design scheme of portable self-referenced digitalization system is introduced in terms of mechanical structure, mathematic model and software design.The presented system integrates advanced data processing technology,laser scanning technology, stereo vision technology and so on,and can recognize its position by self-reference intellectively.The system consists of structure light subsystem and stereo vision subsystem.During scanning,the structure light subsystem reconstructs single laser line in real time and the stereo vision subsystem aligns it to the global coordinates.As the system is self-referenced,the scanned object can be moved arbitrarily. Experiment result demonstrates that the scanner position precision is 0.05mm,and the overall precision is better than 0.12mm,while the scanning speed is 10,000pts/s.The system can be applied in the surface data inspection and model reconstruction for small-sized work piece and mould.
