Drone and satellite AI for map and GIS
Problem and task description
We were given the challenging task of the automatic territory map generation using the drone photos and satellite imagery. Within this task we needed to get actual information from photos about geo-located objects like buildings, rivers, lakes, roads, forests, fields and place it on a generated map. The task also included the roofs layout classification and recognition.
We utilized state-of-the-art and our own technologies based on computer vision, object detection, image segmentation and image processing to bring AI into this field. Our solution is a part of big pipeline that can do the following:
- Detect objects, determine its types and geometry on images from drone or satellite
- Recognize buildings and their geometry, including roofs layout, building type, its height and size
- Recognize roads, lakes, rivers, and put them on the map
- Analise forests configuration, detect changes over time by comparing with previous observations
