# Citrus-Farm-Dataset
![Leading Image](docs/figures/leading_image.png)

## Introduction
CitrusFarm is a multimodal agricultural robotics dataset that provides both **multispectral images** and **navigational sensor data** for localization, mapping and crop monitoring tasks.
- It was collected by a wheeled mobile robot in the [Agricultural Experimental Station](https://cnas.ucr.edu/resources/agricultural-experiment-station) at the [University of California Riverside](https://www.ucr.edu/) in the summer of 2023.

Other notes regarding GPS frame:
- With one GPS receiver on the robot, we can access only the 3D position (rather than full 6-DoF pose) of the robot. Therefore, the orientation (quaternion) component of LiDAR-GPS extrinsic parameters is not very meaningful.
- More precisely, the GPS-RTK data is with respect to the center of the GPS receiver; if your algorithm output is expressed in IMU or LiDAR frame, it is better to convert it to the GPS frame first and align orientation using SVD, before computing the actual error (e.g., Absolute Trajectory Error (ATE)). We provide such evaluation scripts in the [tools](tools.html) as well.

## CitrusFarm Dataset
CitrusFarm is a multimodal agricultural robotics dataset that provides both **multispectral images** and **navigational sensor data** for localization, mapping and crop monitoring tasks.
- It was collected by a wheeled mobile robot in the [Agricultural Experimental Station](https://cnas.ucr.edu/resources/agricultural-experiment-station) at the [University of California Riverside](https://www.ucr.edu/) in the summer of 2023.
- It offers a total of **nine** sensing modalities, including stereo RGB, depth, monochrome, near-infrared and thermal images, as well as wheel odometry, LiDAR, IMU and GPS-RTK data.
