The Freiburg Forest dataset was collected using our Viona autonomous mobile robot platform equipped with cameras for capturing multi-spectral and multi-modal images. The dataset may be used for evaluation of different perception algorithms for segmentation, detection, classification, etc. All scenes were recorded at 20 Hz with a camera resolution of 1024x768 pixels. The data was collected on three different days to have enough variability in lighting conditions as shadows and sun angles play a crucial role in the quality of acquired images. The robot traversed about 4.7 km each day. We provide manually annotated pixel-wise ground truth segmentation masks for 6 classes: Obstacle, Trail, Sky, Grass, Vegetation, and Void.

For each spectrum/modality, we provide one zip file containing all the sequences. Each sequence is a continous stream of camera frames. All the multi-spectral images are in the PNG format and the depth images are in the 16-bit TIFF format. For the evaluations mentioned in the paper, we provide two text files containing the train and test splits. If you would like to contribute to the annotations, please contact us. More details and evaluations can be found in our papers listed under publications.

Freiburg Forest Raw

The raw dataset contains over 15,000 images of unstructued forest environments, captured at 20Hz using our Viona autonomous robot platform equipped with a Bumblebee2 stereo vision camera.

Freiburg Forest Multi-Modal/Spectral Annotated

The dataset contains the following multi-modal/spectral images with groundtruth annotations: RGB, Depth, NIR, NRG, NDVI, EVI and their variants. Pixel-level annotations are provided for 6 semantic classes: Trail, Grass, Vegetation, Obstacle, Sky, Void.


A software implementation of this project (AdapNet++, SSMA, AdapNet, CMoDE) based on TensorFlow can be found on our GitHub repository.
