Visualization of a synchronized stream of event data

[Daehyun Kang]

Hello. I had a question that prompted me to post here.
I want to get an image like the one below from an aedat file.

What would I need to do to do that?

I would really appreciate an answer and thanks for reading.

Hi,

We do not provide an out-of-the-box solution to create such an image.

However, assuming there is an aedat4 file containing synchronized frames and events, you could use dv-processing and OpenCV to create a similar one yourself: 

• The first thing needed to be done is to read events and frames over time. We demonstrate how to do this using dv-processing in here. We even provide a C++ sample exactly for that with visualization.
• To create a similar image as the one shown, you can sort and concatenate image frames and event "frames" by using their timestamps.
  

I hope this helps.

Best Regards,
