Semantic Segmentation using Deep Convolutional Neural Networks
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.
