Mosaic REALMAP: Explore Prague in detail with 1.26M images

author here. Hello!

This dataset is the result of many, many hours of actual driving, with our own camera hardware (mosaic X, designed and built right here in the czech republic) and dual RTK + GNSS/INS/VSLAM system to allow extremely precise positioning.

I would like to encourage adhering to the CC-BY-NC-SA license as much as possible. I would like to at least have a quick dialog which each person who grabs this dataset to explain this as clearly as possible.

This data is not public domain. It was created through tremendous effort and sunk cost, and I would like people to use it for research / learning purposes and to share their results with the world. Releasing all the data with a public link is honestly a bit too scary for me at this point.

Hence the signup form :-)\

After you sign up, you'll get a link to the dataset. First a link to a very small dataset, which is all we have managed to anonymize so far (we have to obscure faces and license plates in order to adhere to GDPR legislation). We will make the entire dataset available in a few weeks.

Thanks for making the dataset available. As I recorded several city walks with multiple cameras simultaneously (usually 3-6 Osmo Pocket in 4K60) I'd like to create Gaussian splatting datasets from many such walks. What costs and hardware requirements can be expected for city-wide GS datasets like the one of Prague?

I'm wondering if I can create them myself or should donate the many TB of multicam recordings.
