Earth Observation / Remote Sensing
- GIS data
- Can be taken from many means - remote sensing != satellite, can include drone / other cameras
- Drones vs satellite imagery
- Drones are similar, but scale is abit different
- Drones vs satellite imagery
- What do EO images look like?
- Typically Hyperspectral images
- Nowadays also look at SAR images
Earth observation images
- Common use cases of such images include LULC, weather monitoring, disaster relief
- Deep learning and EO, 2 types:
- Processed on edge (in orbit, on drone)
- Benefits - save bandwidth … but I believe it is out of scope since it is highly unlikely that Continental will have its own fleet / constellation of satellites.
- Previously this was what I was working on using the nvidia agx xavier. Problem that I was solving was … show gif of results
- Post processed on ground
- Focus of today presentation
- Processed on edge (in orbit, on drone)
Benefits of satellites vs traditional methods
- Near real time (what is the time window?)
- Viable these days using satellite company’s API
Change detection
- Disaster relief
How all of this relates to AI, and to the automotive industry

- satellite imagery to tag road features in a bid to improve GPS navigation in all of these cases, as well as planning and providing disaster relief when road conditions may be dramatically altered.

- Automated road information acquisition from remotely sensed data is always an interesting research area due to its promising values in various applications, e.g., autonomous driving (Wei et al., 2020,Yang et al., 2020), road network mapping making (Senthilnath et al., 2020), road network planning (Wang et al., 2021c,Zhang et al., 2020), traffic control and management (Zhou et al., 2020), map navigation and smart city construction (Chen et al., 2021b,Tan et al., 2020), etc.

Motion prediction, Occupancy and Flow prediction challenges
-
Real time transportation updates?
- movement of goods and people, allowing transportation companies to optimize routes and schedules. This can help improve efficiency and reduce costs, ultimately leading to improved profitability.
- Pose estimation based on satellite image
- Geolocalization using ground-to-satellite cross-view image retrieval
- Knowing the exact location of a vehicle is critical for autonomous cars, and currently GPS systems are being used which the researchers claim suffer from limited precision and are sensitive to multipath effects — such as in “urban canyons” formed by tall buildings.
From <https://developer.nvidia.com/blog/satellite-images-help-track-a-vehicle/>

- The method consists of a Siamese network that learns feature embeddings suitable to matching groundlevel imagery with their corresponding satellite view

- Beyond Cross-view Image Retrieval: Highly Accurate Vehicle Localization Using Satellite Image [Yujiao Shi]
- Although this work was motivated by the poor accuracy of conventional image retrieval-based localization, we do not intend to replace the image retrieval-based localization technique. Instead, city-scale place retrieval can provide an initial estimate for a query camera. Our method then refines this pose estimate to higher accuracy
