Question about kittiHelper.launch #11

Closed Gatsby23 closed 4 years ago

Gatsby23 commented 5 years ago

I have download the Kitti Velodyne bag files into my data folder, but it doesn't work. Should I download the color sequences or the gray sequency to the same folder?

Hello, the same question here. According to the manual, if one wants to try KITTI demo, it is necessary to:

It is not stated whether all datasets gray/color/lidar are needed or not, and what exactly corresponds to YOUR_DATASET_FOLDER? Which directory of the folder structure is needed here? There are data_odometry_X.zip files (X=gray,color,velodyne) with dataset/sequences/00 underneath Which folder is used as YOUR_DATASET_FOLDER in kitti_helper.launch file?

It is not explained. I tried adding: $UNZIP_LOC/ $UNZIP_LOC/dataset/ $UNZIP_LOC/dataset/sequences/

and providing with sequence number 00, 01, etc.. It does not seem to be reading at all. Could you provide some hints on this?

It is really misleading if it is written that some functionality exists but it is not possible to make it work by following simple instructions.
