| 摘 要： | 基于条纹投影方法和主动三角化技术，详细分析三维光学数字成像系统的性能，并对其进行仿真分析。首先简单描述系统的结构。然后定量分析各个参数对系统性能的影响，具体包括：成像系统出瞳和测量参考面之间的距离；成像系统出瞳和投影系统入瞳之间的距离；投影条纹的空间周期。最后用模拟数据对系统进行验证，结果说明所得到的三维测量数据更加精确。

| Abstract: | Based on the projection of fringe pattern and on active triangulation, it is analyzed the performance of a 3D full-field imaging system and the simulation analysis is presented. First, we briefly describe the system setup and give an exact mathematical relationship between the height of objects surface, the phase and the experimental setup parameters. Using this relationship, the shape of objects can be obtained precisely. Then, the influence on the measurement results introduced by an inaccuracy in the determination of the systemic parameters is investigated in detail. Finally, the experiments are carried out to evaluate the measurement performance using the simulated data. |
