In this paper, we present a generic performance model able to evaluate the accuracy of depth estimation using depth from defocus (DFD). This model only requires the sensor point spread function at a given depth to evaluate the theoretical accuracy of depth estimation. Hence, it can be used for any (un)conventional system, using either one or several images. This model is validated experimentally on two unconventional DFD cameras, using either a coded aperture or a lens with chromatic aberration. Then, we use the proposed model for the end-to-end design of a 3D camera using an unconventional lens with chromatic aberration, for the specific use-case of small unmanned aerial vehicle navigation.

非常规相机离焦深度性能模型

在本文中,我们提出了一种通用性能模型,能够使用离焦深度 (DFD) 来评估深度估计的准确性。该模型只需要给定深度的传感器点扩散函数来评估深度估计的理论精度。因此,它可以用于任何(非常规)系统,使用一个或多个图像。该模型在两个非常规 DFD 相机上进行了实验验证,使用编码光圈或具有色差的镜头。然后,我们将所提出的模型用于使用具有色差的非常规镜头的 3D 相机的端到端设计,用于小型无人机导航的特定用例。
