摘要:

我们描述了一个开源模拟器,它可以创建城市环境中典型汽车场景的传感器辐照度和传感器图像。该系统的目的是支持汽车应用的摄像头设计和测试。用户可以指定场景参数(例如,场景类型、道路类型、交通密度、一天中的时间)来从存储在数据库中的图形资源中组装大量随机场景。使用定量计算机图形学方法生成传感器辐照度,并使用图像系统传感器模拟创建传感器图像。合成传感器图像具有像素级注释;因此,它们可以用于训练和评估神经网络以用于成像任务,例如目标检测和分类。端到端仿真系统支持汽车应用的定量评估,从场景到摄像头再到网络精度。

英文摘要:

We describe an open-source simulator that creates sensor irradiance and sensor images of typical automotive scenes in urban settings. The purpose of the system is to support camera design and testing for automotive applications. The user can specify scene parameters (e.g., scene type, road type, traffic density, time of day) to assemble a large number of random scenes from graphics assets stored in a database. The sensor irradiance is generated using quantitative computer graphics methods, and the sensor images are created using image systems sensor simulation. The synthetic sensor images have pixel level annotations; hence, they can be used to train and evaluate neural networks for imaging tasks, such as object detection and classification. The end-to-end simulation system supports quantitative assessment, from scene to camera to network accuracy, for automotive applications.
