本文提出了一种编码孔径的设计方法，并将其安装在投影仪中进行主动深度测量。孔径设计采用遗传算法实现。本文介绍了一种基于投影仪和摄像机的深度测量系统。该系统包括一个带有编码孔径的原型投影仪，该投影仪使用离焦深度（DfD）技术来重建形状。然后，我们提出了一种创建编码孔径的方法，以获得最佳的深度测量性能。我们还提出了一种有效的离焦参数校准技术和DfD的代价函数，以提高精度和鲁棒性。实验结果表明，该方法可以在考虑噪声的情况下模拟生成孔径图进行适应度计算。利用我们的深度测量算法进行了评估，以确认所提出的模式优于其他模式。
This paper proposes a method for designing a coded aperture, which is installed in a projector for active depth measurement. The aperture design is achieved by genetic algorithm. In this paper, a system for depth measurement using projector and camera system is introduced. The system involves a prototype projector with a coded aperture which is used to reconstruct a shape using Depth from Defocus (DfD) technique. Then, we propose a method to create a coded aperture to achieve the best performance on depth measurement. We also propose an efficient calibration technique on defocus parameters and a cost function for DfD to improve the accuracy and the robustness. Experimental results show that the proposed method can create an aperture pattern using simulation considering noise for fitness calculation. Evaluations are conducted to confirm that the proposed pattern is better than other patterns with our depth measurement algorithm.
