I have the same problem also ,did you solve it?
Hi,
When I was trying to run SVIn with the cave dataset, I saw the following error.
W0808 10:25:20.626619 336858 Subscriber.cpp:172] Frame delayed at time 1532199354.547382399 W0808 10:25:20.634047 336858 Subscriber.cpp:172] Frame delayed at time 1532199354.547884700 terminate called after throwing an instance of 'okvis::FrameSynchronizer::Exception' what(): [Exception] /home/jingyu/frog/svin_ws/src/SVIn/okvis_ros/okvis/okvis_multisensor_processing/src/FrameSynchronizer.cpp:128: detectionCompletedForAllCameras() assert(frameBuffer_[position].first->timestamp() > lastCompletedFrameTimestamp_ && (lastCompletedFrameId_ == 0 || frameBuffer_[position].first->id() > lastCompletedFrameId_)) failed: wrong order! timestamp last: 1532199354.547382399 timestamp new: 1532199354.399061650 id last: 25903 id new: 25548 [okvis_node-4] process has died [pid 336858, exit code -6, cmd /home/jingyu/frog/svin_ws/devel/lib/okvis_ros/okvis_node /camera0:=/cam0/image_raw /camera1:=/cam1/image_raw /imu:=/imu/imu __name:=okvis_node __log:=/home/jingyu/.ros/log/874f02ca-35f5-11ee-b9cb-8d5efeec27ae/okvis_node-4.log].
I tried to play the rosbag at different rates (0.1-1.0) but this issue still happenned.
Would you mind providing any insight about why this happens? Thanks!
This problem shows that there are duplicate frames in the frames corresponding to time 532199354.547382399 in the Cave data set, that is, the timestamps of two adjacent frames are equal. My solution is to add code to determine whether the timestamps are equal in the data subscription node, so as not to add duplicate frames to subsequent KFVIO.
It should work now as I have added stereo synchronizer to the code.
