syncronisation of multiple cameras #16

Open phil333 opened 4 years ago

phil333 commented 4 years ago

I need a stereo camera, and I am having issues with the synchronisation of both cameras. While the images are taken at the same time, they are published with a significant delay.

if I wanted to improve the publishing speed, where would I start?

I faced synchronization problems with ROSIntegration but resolved them by setting bSimulateTime to false inside of my game instance (which is a child of UROSIntregrationGameInstance).

hi @Tim-Fronsee , I just tried that, but that doesn't work for me. The problem seems to be with the processing of the images. While they images are taken at the same time, there is a publishing interval. The interval is bigger, if the images are bigger in resolution.
