Backup navigation system for unmanned aerial vehicles
11656638 · 2023-05-23 · ·

Described is a method that involves operating an unmanned aerial vehicle (UAV) to begin a flight, where the UAV relies on a navigation system to navigate to a destination. During the flight, the method involves operating a camera to capture images of the UAV's environment, and analyzing the images to detect features in the environment. The method also involves establishing a correlation between features detected in different images, and using location information from the navigation system to localize a feature detected in different images. Further, the method involves generating a flight log that includes the localized feature. Also, the method involves detecting a failure involving the navigation system, and responsively operating the camera to capture a post-failure image. The method also involves identifying one or more features in the post-failure image, and determining a location of the UAV based on a relationship between an identified feature and a localized feature.

HIGH FIDELITY ANCHOR POINTS FOR REAL-TIME MAPPING WITH MOBILE DEVICES
20230194301 · 2023-06-22 ·

Methods, systems and computer program products, for map data collection. An anchor point creation mode is activated on a mobile data collection device when the mobile data collection device enters a geographical anchor point creation area. In the anchor point creation mode, the mobile data collection device collects and streams mapping raw data to a remote computing device. A high definition map of the anchor point creation area is created by combining received raw data with mapping data from other data sources. After the map has been created, when a mobile data collection device enters the anchor point creation area, information from the map is used in a data capture mode to refine a determination of a position and/or orientation of the mobile data collection device, and a position and/or orientation of one or more features detected by the mobile data collection device.
