BlinkSim

A versatile simulator for advancing research in event-based and RGB-event data fusion.

Demos

Automatically generated results where objects are randomly selected from a pool and then placed and moved according to some pre-defined rules (also the camera):

Rendered result of customized scene:

Features

• Event simulation: event data simulated from high-frequency rendering data
• Simulation of low dynamic range, motion blur, defocus blur and atmospheric effect
• Dense point tracking: provide tracking ground truth for each pixel at any frame and any object
• Forward/backward optical flow
• Depth maps

Datas that are not shown in the demo but are also accessible

• Normal maps
• Instance segmentation
• Camera poses and intrinsic
• Object poses
