ORB SLAM2 mono no response #787

Open eeyzl5 opened 5 years ago

eeyzl5 commented 5 years ago

When I tried to run monocular orb slam2 on both TUM and KITTI datasets, there is no any response, no error, no display and just stuck without any output. I also tried the ROS version and it has the same problem. However, when I then tried stereo orb slam2 with EuRoC dataset and everything just went well. So I am not sure if it's the problem of the dataset or the installation of orb slam2 mono. Very glad if anyone could give me some hints.

Hello @eeyzl5 Can you give the command that you run? Which dataset in TUM are you running? Thanks

eeyzl5 commented 5 years ago

Hi @Alexandre34

For the mono orb slam2 I just ran the command provided in README: ./Examples/Monocular/mono_tum Vocabulary/ORBvoc.txt Examples/Monocular/TUM1.yaml home/daniela/Downloads/rgbd_dataset_freiburg1_xyz/rgb

I was using freiburg1 dataset.

For the ROS version I ran a node like this: rosrun ORB_SLAM2 Mono Vocabulary/ORBvoc.txt Examples/Monocular/TUM1.yaml

Then play the rosbag: rosbag play rgbd_dataset_freiburg1_desk.bag

Both attempts failed without any response and output.

Thanks!

@eeyzl5 Try ./Examples/Monocular/mono_tum Vocabulary/ORBvoc.txt Examples/Monocular/TUM1.yaml home/daniela/Downloads/rgbd_dataset_freiburg1_xyz (without the /rgb at the end) By default the monocular mode reads the file rgb.txt in the folder sequence specified then reads the images. Because there are no rgb.txt file in the rgb folder it doesn't read anything.

@Alexandre34

Thanks for your advice but unfortunately it's still the same problem. Probably it's the problem of the installation?

Alexandre34 commented 5 years ago

@eeyzl5 Ok that's weird. Try to reinstall the library and make sure that OpenCV and Eigen are of the right versions.

Oh! I eventually find out the stupid mistake. I missed a '/' before 'home' that specifies the path to sequence folder. After I add the '/' everything just works fine. Thank you so much for your help!
