Query: The ParallelEye Dataset: Constructing Large-Scale Artificial Scenes for
  Traffic Vision Research   Video image datasets are playing an essential role in design and evaluation
of traffic vision algorithms. Nevertheless, a longstanding inconvenience
concerning image datasets is that manually collecting and annotating
large-scale diversified datasets from real scenes is time-consuming and prone
to error. For that virtual datasets have begun to function as a proxy of real
datasets. In this paper, we propose to construct large-scale artificial scenes
for traffic vision research and generate a new virtual dataset called
"ParallelEye". First of all, the street map data is used to build 3D scene
model of Zhongguancun Area, Beijing. Then, the computer graphics, virtual
reality, and rule modeling technologies are utilized to synthesize large-scale,
realistic virtual urban traffic scenes, in which the fidelity and geography
match the real world well. Furthermore, the Unity3D platform is used to render
the artificial scenes and generate accurate ground-truth labels, e.g.,
semantic/instance segmentation, object bounding box, object tracking, optical
flow, and depth. The environmental conditions in artificial scenes can be
controlled completely. As a result, we present a viable implementation pipeline
for constructing large-scale artificial scenes for traffic vision research. The
experimental results demonstrate that this pipeline is able to generate
photorealistic virtual datasets with low modeling time and high accuracy
labeling.
