Mapillary’s computer vision technology automatically detects objects depicted in images, such as buildings, cars, pedestrians, bicycle racks, and much more. Since each image has geocoordinates, it is possible to also visualize the object detections on the map.
This will allow you to easily get a visual reference to different kinds of objects and filter imagery by what type of objects it contains. The visualizations at this stage reflect positions of the images where certain objects are visible (not the positions of the objects themselves).
This article explains how to explore object detections on the Mapillary web app. To learn more about the different types of map data that Mapillary offers, and object detections more specifically (including the list of detected object types), see the respective help articles.
Browsing object detections
- To turn on object detections, click on the "Map data" icon at the top of the Mapillary web app and make a selection under either "traffic signs" or "points"
- The dropdown arrow will show a variety of traffic signs and points you can display on the map
- The map will change to give you a better visualization of the detections
- You can return to the normal map view by pressing "Reset selection"
You will see some example object classes to help you start exploring detections. Click on e.g. cars, crosswalks, or trash cans to filter for images where these objects can be seen. Alternatively, you can use the search box to search for whatever objects interest you. As you type, you will see a list appear that helps you match your search to the available classes. To exit the list, press Esc on your keyboard.
The currently applied filters appear above the search box and you can remove any of them by clicking on the cross on the respective label.
You can close the detection browsing window at any time by clicking the cross at its top right corner or the “Map data” button. Your applied searches will remain active and you can access the search box any time by just clicking on the “Map data” menu again.
As you apply object class filters, you might not see anything on the map at first if you are at a low zoom level (less than level 10).
