Wow, driving in the pedestrian zone around Staromák is bad enough already, but they also happily post pictures. Not okay.
Maybe they got some special permission?
There is zero mention of privacy in the post so probably not.

#23So how do we explore? Is there a link somewhere in the article?
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.

#24Hate that I can't put this on wiki commons because of the non-commercial license.
Hi, sorry but that is not the purpose of this data. We are releasing it for research and education purposes.
You might redirect your critique to the other ~1000 companies in the world who have such data and don't release anything at all under any terms.

We obeyed all laws when capturing this data. As you might notice, old town square does allow vehicles under special circumstances (delivery vehicles, mostly)

#28Hi everybody, wow we are on the front page of HN! What a dream come true!
So far we have had a few hundred signups for the data. I ran the applications through chatGPT to get an idea of what people want to do with the data:
Research and Academic Purposes: A significant number of respondents plan to use the dataset for research in areas like computer vision, 3D reconstruction, Gaussian splatting, neural rendering fields (NeRF), and autonomous driving. Many aim to publish papers, conduct experiments, or work on academic projects such as theses.
Learning and Educational Use: Many individuals expressed interest in using the dataset for learning purposes, personal education, or as a teaching aid. This includes students working on class projects, hobbyists looking to enhance their skills, and educators seeking material for
lectures and demonstrations.
Personal Projects and Hobbyist Exploration: A considerable portion of respondents wish to explore the dataset for personal enjoyment or hobby projects. This includes experimenting with new technologies, exploring the city virtually, or simply satisfying personal curiosity.
Virtual Reality (VR) and Augmented Reality (AR) Applications: Numerous users intend to integrate the dataset into VR/AR environments using platforms like Unreal Engine and Unity. Applications range from creating immersive experiences and simulations to developing VR walkthroughs and gaming environments.
Video Creation, Animation, and Visual Effects (VFX): Several respondents plan to use the dataset for filmmaking, creating animations, or experimenting with visual effects. This includes producing content for personal portfolios, social media, and non-commercial projects.
Experimentation and Testing: A number of users are interested in testing new technologies, workflows, or software capabilities using the dataset. This includes experimenting with rendering techniques, 3D modeling, and spatial data handling.
Gaussian Splatting and Advanced Rendering Techniques: Many respondents specifically mentioned Gaussian splatting as an area of interest. They plan to use the dataset to test, implement, or improve techniques related to point-based rendering and large-scale scene visualization.
Game Development: Some users aim to incorporate the dataset into game development projects. This includes creating realistic environments, developing game mods, or using the data as reference material for designing game levels.
Artistic and Creative Projects: A subset of respondents expressed intentions to use the dataset for artistic endeavors, such as digital art installations, motion graphics, and experimental visualizations.
Virtual Tourism and City Exploration: A few individuals plan to use the dataset to virtually explore the city, create virtual walking tours, or develop tools that allow others to experience Prague remotely.
Key Takeaways: High Interest in Research and Education: The dataset is highly valued for its potential to contribute to academic research and educational purposes.
Strong Enthusiasm for VR/AR and Advanced Visualization: There's a notable enthusiasm for using the dataset in VR/AR applications and exploring advanced rendering techniques like Gaussian splatting.
Diverse Range of Uses: Respondents show a wide range of interests, from personal exploration and hobby projects to professional development and creative arts.

#29crazy! wont be too long until this is here for major cities as well.
Prague is the capital of Czech Republic and has over 1.3 million inhabitants, so I'd say it qualifies as a "major city"
I love Prague and I spent a quarter of century living there, but its status as a major city depends on context.
In the list of world cities by population, it ranks 403rd.

For Czechs or Central Europeans in general, it is a major city, but not in worldwide context.

Sorry it's just a mild complaint. I am still happy that this dataset exists! Just my first thought was "ah I will put it on Wikimedia Commoms", and then... I realize I can't.
