Which algorithms are used by Google Maps

Image sources

Street View photos come from two different sources: Google and users.

Content from Google

Google content has the addition of "Street View" or "Google Maps". Faces and license plates are automatically made unrecognizable in our pictures.

User content

For user content, a clickable or tapped account name and sometimes a profile picture is displayed.

This is how Google Street View works

Our technical team put a lot of work into making the Street View images public. You can find more information here.

  • STEP 1

    take photos

    First of all, we have to drive through the places and take photos of them so that we can show them in Street View. When and where we drive depends on many factors, such as the weather and the population density of the various areas. After all, we always want to take the best pictures.

  • STEP 2

    Align images

    There are sensors attached to the car that measure the GPS location, speed and direction of travel. We correlate the received signals with each other in order to assign the correct geographical location on the map to each image. This enables us to better reconstruct the exact route of the car and even tilt and realign the images as required.

  • STEP 3

    From photo to 360 ° recording

    The images are taken by cameras that are next to each other and overlap somewhat. They are then merged into a single 360 ​​° exposure. This is how we avoid creating gaps. We then use special algorithms for image processing with which the transitions are processed in such a way that they can no longer be recognized as far as possible.

  • STEP 4

    Always the right picture

    We use the speed at which the car's three lasers reflect off surfaces to determine how far away a building or object is. This data enables us to create 3D models from it. If you move the mouse towards a point in the distance, the optimal panorama of this place is displayed in this 3D model.

We still want to go here

We are on the road in many countries with our Street View vehicle. With our recordings you can explore places all over the world. In the country list you can see where we will be soon.

Due to factors that are beyond our control, it is always possible that our vehicles cannot start or that there are minor deviations. This can be the case, for example, in bad weather conditions or when roads are closed. Smaller towns and villages in the vicinity may also be included when specifying town names.

Thousands of users use Google Maps every day and we want to make sure that you can find your way to the places whenever you want. To do this we need to be sure to use the correct street names, street signs, routing, and information about shops and other places of interest to you. That is why we will resume trips through large parts of Germany from June 29, 2020. At the top of this page you will find all the information about where we are right now.

We know that there is a lot of interest in our camera cars. They are the same cars that we used in the past to take pictures for Street View. In the coming trips we will only use the images to improve Google Maps and have no plans to publish them.

We have already been here

The blue areas on the map show where Street View footage is available. If you want to see more details, just zoom in on the picture. You can also find the content on our websites and in our apps.

The Google Street View vehicles

In the overview you can find out more about our Street View vehicles.

  • Street View car

    A lot has happened since Street View was launched in the US in 2007. There are now our 360 ° photos of places on all continents.

  • Street View Trekkers

    With our Trekker we can show even more places around the world in Street View - places that no car, trike, trolley or snowmobile can get to. The Trekker is a backpack with a camera system mounted on top. With it we can take pictures of places that can only be reached on foot via narrow paths or narrow passages. Our first recordings with this camera technology come from the rough and rocky terrain of the Grand Canyon in the US state of Arizona.

  • Street View trolley

    When a group of art-loving Google employees wanted to use Street View technology in museums around the world, we had to develop a system that could easily fit through museum doors and walk around sculptures with ease. For indoor recordings, all the necessary equipment had to fit on a smaller frame. The result was a kind of luggage cart with a camera system mounted on it: the Street View trolley. We used it not only to take pictures for Street View in museums, but also in other buildings such as the White House or in sports stadiums.

  • Street View snowmobile

    We imagined it would be funny to take the Street View cameras with us on the slopes. Our team spent several weekends securing the Street View equipment to a snowmobile using squared lumber, duct tape, and additional hard drives wrapped in ski jackets to protect them from freezing temperatures. The result: Now skiers, snowboarders and snowshoe hikers can explore Whistler Blackcomb Mountain and the hilly, snow-covered terrain of adjacent ski areas.

  • Street View Trike

    For cities with narrow streets, we needed a vehicle that was not only manoeuvrable, but could also easily transport the Street View Trekker. So that we can also reach the narrowest streets, our team opted for the Indonesian scooter Selis Robin. May we introduce: the Street View Trike! This vehicle has been fitted with an additional mast specially designed to stabilize the Street View Trekker.
