Prophesee camera plug-ins for DV or libcaer

[jonah.s...@gmail.com]

Hello, 

I was wondering if there is the ability to utilize Prophesee or Prophesee-partner cameras with DV or even libcaer. I would imagine we would have to write our own plug-in for the camera in libcaer and corresponding object in DV. Is there an established way to do this?

Hello,

plugging them into libcaer would be very involved and not make much sense, as libcaer is specifically the low-level abstraction layer for our cameras.

To add them to DV, you'd simply write a DV module that has no inputs, only outputs, which uses whatever low-level camera access library Prophesee makes available to get the data and format it into our output formats.

Luca - thanks for the quick reply. I would follow something close to this tutorial, correct? https://inivation.gitlab.io/dv/dv-docs/docs/first-module/

I would also adapt the CMakeLists to also add the Prophesee libraries, right?

[Luca Longinotti]

Correct on both counts, yes.

Hello,

I'm also dealing with that. I'm wondering how to format data. Could you give me more detailed guidance?

Within our frameworks we use AEDAT4 data formats, so events are dv::EventPacket, frames are dv::Frame, IMU data is dv::IMUPacket.

You'd basically have to create these datatypes and set their fields with the data you get from the competitor's camera.
