# LiDAR Degeneracy Datasets
Dataset associated with submission for handling LiDAR-degenerative environments through LiDAR-radar-inertial fusion with factor graphs.
The datasets consist of sensor measurements (IMU, LiDAR, and FMCW radar) of an aerial robot manually flown through environments challenging for LiDAR sensors. These are a biking tunnel (geometric self-similarity) and a university corridor filled with fog (obscurants). In addition CAD extrinsics between the sensors are provided.
## Environments
### [Fyllingsdalen Tunnel](https://maps.app.goo.gl/Crj1o13NznuE5fZn8)
Manual flight along a 8m-wide, 500m-long, straight section of a biking tunnel in Bergen, Norway.
Bag files can be found [here](https://ntnu.box.com/s/congyw29kpo80exau7e1tpeyoqay6u9d)
### [Fog-Filled University Corridor](https://maps.app.goo.gl/V5ZfTVAy4xxQHPzs5)
Manual flight in a university environment in the Elektro building of NTNU in Trondheim, Norway. The first corridor flown through after takeoff is filled with dense fog.

#### Sensors
Synchronized using microcontroller-based internally developed synchronization/triggering module
- [Ouster OS0-128 LiDAR](https://ouster.com/products/scanning-lidar/os0-sensor/)
- [VectorNav VN100 IMU](https://www.vectornav.com/products/detail/vn-100)
- [Texas Instruments IWR6843AOP-EVM Radar](https://www.ti.com/tool/IWR6843AOPEVM)
The header time stamp for IMU and radar originate from the triggering module, to replay the trigger-stamped LiDAR data from packet topics use [this](https://github.com/ntnu-arl/ouster-ros/tree/dev/sensor_sync_replay) driver.
