You can download the dataset on the data page. The dataset is split into ZIP archives of sizes up to 25 GB based on the sensor, data modality, the scene, etc. Please refer to the column “Chunk file” in the “Skoltech3D data” spreadsheet for the correspondence between the pieces of the dataset and the names of the ZIP files.
For convenience, we provide a python downloader to download specific parts of the dataset. The script is coming soon.
