Optical flow: wrong flow for moving objects when replay a captured Carla file #4611

Open mawistc opened 3 years ago

mawistc commented 3 years ago

CARLA version: 0.9.12 Platform/OS: Windows and Ubuntu 18.04 Problem you have experienced: Incorrect optical flow, from moving objects are wrong. Looks like only global ego motion is calculated What you expected to happen: Get correct optical flow data

Steps to reproduce: Set a Optical flow camera sensor Record a Carla file - client.stop_recorder() Relay the Carla file and store Optical flow camera sensor data - client.replay_file("record.log"))

@MatthiasWildeBusiness does this only happen for the playback of a recorded file? What if you record the sensor data during the initial simulation - are the OFs for moving object correct, then?

Hi, actually this happens during rendering directly. Replaying a captured file is not supported at all since this is a kind of "set positions" mode and can not calculate flow.
