论文摘要
我们评估智能手机摄像头模拟的准确性。该仿真是端到端分析，从高动态范围3D场景的物理描述开始，并包括光学和图像传感器的规范。将模拟与场景的物理版本的测量进行了比较。图像系统模拟准确地匹配了光学模糊，景深，光谱量子效率，场景间反射和传感器噪声的测量。结果支持使用图像系统模拟方法用于软原型摄像机，并在机器学习应用程序中生成合成数据。
We assess the accuracy of a smartphone camera simulation. The simulation is an end-to-end analysis that begins with a physical description of a high dynamic range 3D scene and includes a specification of the optics and the image sensor. The simulation is compared to measurements of a physical version of the scene. The image system simulation accurately matched measurements of optical blur, depth of field, spectral quantum efficiency, scene inter-reflections, and sensor noise. The results support the use of image systems simulation methods for soft prototyping cameras and for producing synthetic data in machine learning applications.
