[Viso2] Performance on a Jetson TX1

Hi,

I need to track the driving line of a car in real time. I decided to use libviso2 as it provides fairly accurate results, however so far I didn't have a setup that allowed realtime in-car calculations. The Jetson TK1 is too slow (taking >1s per Visual Odometry calculation). Does anyone have experience with the speed of the Jetson TX1? Would it be able to have ~10 fps using the libviso2 library?

Thanks in advance Tim

If you are building packages from source, make sure to enable optimisations (ie: build with -DCMAKE_BUILD_TYPE=Release or RelWithDebInfo).

Thanks for your answer. The library is build in Release Mode, so that's not the problem.

A bit late - but I have had a similar problem. If you profile it, it only uses one of the four cores, and no gpu's. I would suggest extending the library to use these and you'll get a much higher frame rate.

I ended up using the ZED 3D cameras VO capabilities, which delivered pretty good and fast results.

Ah - ok. Good to know - thanks. I'm going to stick with it a bit for now as we have bought a Bumblebee XB3.

Oh - forgot to add. I have tried it on the TK1 and TX1 and not much improvement....

I mean between the two boards - so multithreading and gpu seems the way to go.
