Hi! I have a similar issue to https://github.com/uzh-rpg/rpg_esim/issues/10. I have followed @supitalp 's opinion. https://github.com/uzh-rpg/rpg_esim/issues/10#issuecomment-446555859 But I haven't modified the file,it's default.

Here is my error output: $ rosrun esim_ros esim_node \ --data_source=2 \ --path_to_output_bag=~/sim_ws/tmp/out.bag \ --path_to_data_folder=/home/seaeast/sim_ws/tmp/demo/frames/ \ --ros_publisher_frame_rate=10 \ --exposure_time_ms=10.0 \ --use_log_image=1 --log_eps=0.1 --contrast_threshold_pos=0.15 --contrast_threshold_neg=0.15

Any help would be really appreciated thanks

There are no problems in catkin build esim_ros progress. And my ROS version is melodic.

There is another error output:

Hi! I'm also facing the same issue any leads for resolving the same (Using ROS Melodic by the way) Thanks

You should change path to the camera calib file: https://github.com/uzh-rpg/rpg_esim/blob/d7708fff4acffec1771297674c4b917b7683d16b/event_camera_simulator/esim_ros/cfg/unrealcv.conf#L15

YuxuanSnow commented 3 years ago

As LarryDong said, you should change the absolute path in .conf file. More specifically, change "user" to your computer name.

I change ‘’user‘’ to my computer name, but it was shown ''No such file or directory''

YuxuanSnow commented 2 years ago

Well, that's depend on where do you install and where is your ROS workspace.

You have to find this file in your computer, and change it according to it (pwd).

VinoDeng commented 2 years ago

Thanks a lot, I have completed event camera simulation successfully via your method
