Viewing-zone (VZ) is an important research topic for stereoscopic displays. Although much research has been done to date, more studies need to be conducted to ascertain the VZ criterion. In this paper, we proposed a novel evaluation method based on optical theory, simulation and experiment to figure out the VZ. We find that the VZ is no more diamond-shaped as the past studies reported.

Abstract. During the measurement procedure of line structured light 3D scanning system, there is a key about how to calibrate the whole measuring system. In order to solve the calibration problem in the line structured light 3D measured system such as requirements for high accuracy calibration models, complicate calibration procedures and so on. This paper presented a calibration method combining the vertical calibration board with 3D scanning measurement system, this method is simple, easy to operate and the assistant adjustment equipment is unnecessary. Experiment showed that this method can attain relative accuracy about 0.51% which indicates the rationality of this method.
