BUILD_BREAK: TF transform error. Flightgoggles unusable #113

Closed SimpleUAVs closed 5 years ago

SimpleUAVs commented 5 years ago

Running flightgoggles from core.launch (and every other launch file) generates the following error:

"Could NOT find transform for /uav/camera/left/nwu in time: "uav/camera/left/nwu" passed to lookupTransform argument source_frame does not exist"

Still there, just runs a LOT slower now. Problem is with the last commit to flightgoggle_ros_bridge with fix to bug #110.

Error message is now:

"Could NOT find transform for /UAV/camera/left/nwu in time: Lookup would require extrapolation into the future. Requested time 58.057310245 but the latest data is at time 58.056268578, when looking up transform from frame [/uav/camera/left/nwu] to fram [world]"

SimpleUAVs commented 5 years ago

still there.

Hi Jeff,

The TF lookup issue that you're seeing is a new issue caused by the fix to #110. It should now be patched in commit d48e586.

Thanks, -Winter

SimpleUAVs commented 5 years ago

Seems to work now. Thanks
