## KITTI dataset
|
||||
|
||||
[](https://www.youtube.com/watch?v=M_ZcNgExUNc)
|
||||
|
||||
We demonstrate the usage of the system with the [KITTI dataset](http://www.cvlibs.net/datasets/kitti/eval_odometry.php) as an example.
|
||||
|
||||
**Note:** The path to calibration and configuration files used here works for the APT installation. If you compile from source specify the appropriate path to the files in [data folder](/data/).
|
||||
|
||||
Download the sequences (`data_odometry_gray.zip`) from the dataset and extract it.
|
||||
```
|
||||
# We assume you have extracted the sequences in ~/dataset_gray/sequences/
|
||||
# Convert calibration to the basalt format
|
||||
basalt_convert_kitti_calib.py ~/dataset_gray/sequences/00/
|
||||
|
||||
# If you want to convert calibrations for all sequences use the following command
|
||||
for i in {00..21}; do basalt_convert_kitti_calib.py ~/dataset_gray/sequences/$i/; done
|
||||
```
|
||||
Optionally you can also copy the provided ground-truth poses to `poses.txt` in the corresponding sequence.
|
||||
|
||||
### Visual odometry
|
||||
To run the visual odometry execute the following command.
|
||||
```
|
||||
basalt_vio --dataset-path ~/dataset_gray/sequences/00/ --cam-calib /work/kitti/dataset_gray/sequences/00/basalt_calib.json --dataset-type kitti --config-path /usr/etc/basalt/kitti_config.json --show-gui 1 --use-imu 0
|
||||
```
