This paper describes how the maximum blur radius affects the depth results by depth from the defocus (DFD) method based on liquid crystal (LC) lens. Boundary frequency is determined by the maximum blur radius. It is found that if the maximum blur radius used in the calculation is larger than the real value, the depth resolution obtained is reduced; on the other hand, if one smaller than the real value is used, the depth resolution in the middle range of the scene is increased, but errors occur in the near and far planes. Using the maximum blur radius close to the real one results in the best depth results.

最大模糊半径对基于液晶透镜的深度传感器的影响

本文介绍了基于基于液晶（LC）透镜的散焦（DFD）方法，最大模糊半径如何影响深度结果的深度。边界频率由最大模糊半径确定。可以发现，如果计算中使用的最大模糊半径大于实际值，则深度分辨率会降低；反之，另一方面，如果使用小于真实值的值，则场景中间范围的深度分辨率会提高，但是在近平面和远平面中都会发生错误。使用接近真实半径的最大模糊半径可获得最佳深度效果。
