Methods and devices for obtaining a geographical coordinate for a position on the ground
Patentradars sammanfattning
Vantor Sweden AB discloses a method and processing device that determines precise geographical coordinates for ground-level positions from an airborne video camera without relying on GNSS. An initial camera pose is bootstrapped by matching at least three manually or semi-automatically identified feature points between a live video frame and a pre-stored textured 3D geo-referenced model; a navigation filter then continuously tracks the camera pose by fusing Visual Odometry and Visual Positioning against the same 3D model. When a user indicates a target location in any subsequent video frame, the system ray-casts through the known camera pose and the 3D model to resolve the georeferenced coordinate of that point in near real-time.
