Portable 3D scanning system based on an inertial sensor

Portable 3D scanning systems are increasingly used in many applications at present as a result of its high flexibility, portability and high efficiency. Iterative closest points method is widely used for multi-view measurement results registration. However, there are many restrictions for portable system, the alignment often depends on landmarks on object surface or object features, in some applications, it may not achieve satisfactory expectations. In this paper, we propose to conduct the registration based on pose estimation from a low cost inertial sensor, which will increase the measurement effectiveness. Test result demonstrates that the method is feasible. With attitude information inside the system, the measurement device does not need external support information and has good prospects for application.
