提出了采用二元光学元件(BOE)进行三维形貌测量的新方法。设计二元光学元件产生空间二维点阵结构光,经物面调制后的点阵信息被相机一次获取,利用三角测量法得到物体的三维空间坐标。按该方法处理得到的结果与实际物体的形貌特征吻合。结果表明,按该测量系统具有便捷式功能,适用于三维照相等应用领域。 A new method of three-dimensional topography measurement using binary optical element (BOE) is proposed. The binary optical element is designed to generate the space two-dimensional lattice light. The lattice information modulated by the object plane is acquired by the camera once and the three-dimensional coordinate of the object is obtained by the triangulation method. The results obtained by this method are consistent with the physical features of the actual objects. The results show that, according to the measurement system has a convenient function, suitable for applications such as three-dimensional photography.
