Mapillary is powered by world‑class computer vision

3D reconstruction and semantic segmentation connect images and extract map data at scale for smart cities, geospatial services, and autonomous vehicles.

How Mapillary works

What we do with computer vision

Find out what happens behind the scenes to turn images into connected street-level views and extract map data at scale.

Privacy blurring
All Mapillary imagery is anonymized for privacy compliance. Our deep learning based algorithms are optimized for blurring faces and license plates on street-level images.

3D reconstruction
Mapillary uses Structure from Motion to find the relative positions of images and create smooth transitions between them. Our OpenSfM pipeline is available as open source.

Image segmentation
Each image is pixel-wise labeled with 97 object classes. We have the best-performing algorithm for semantic segmentation of road imagery, based on Cityscapes and Mapillary Vistas benchmarks.

Traffic sign recognition
We detect more than 1,500 types of traffic signs in 100 countries. When the same sign appears in multiple images, its position in space is triangulated and the traffic sign is extracted as a map feature.
