Error trying to roslaunch object3d_detector.launch about online_learning HOT 3 CLOSED

Hi,

For "[FATAL] [1541099625.238843188]: Error opening file: ~/MassVassar.bag" please refer to:

https://answers.ros.org/question/41665/error-opening-file-mylaserdatabag/

For "[ERROR] [1541099625.248293481]: Unable to open calibration file", please first check if the file path is correct, i.e. "/home/golnaz/online_ws/src/online_learning/object3d_detector/config/vlp16.yaml"

Hi,

I can open the bag file and the code works very well, thanks!

I still get an error with opening the yaml calibration file as follows:

YAML Exception: yaml-cpp: error at line 0, column 0: invalid node; this may result from using a map iterator as a sequence iterator, or vice-versa
[ERROR] [1541969450.088823936]: Unable to open calibration file: /home/golnaz/online_ws/src/online_learning/object3d_detector/config/vlp16.yaml

The code still runs even without that file. Would opening the yaml file increase the accuracy of the algorithm, or should I not even worry about it?

Thanks!

Hi

Yes, the calibration file is required by "velodyne_pointcloud" package, and the calibration do increase the accuracy of the data.
