Abstract: Disclosed are methods and systems for generating three-dimensional reconstructions of environments. A system, for example, may include a housing having an image sensor directed in a first direction and a distance sensor directed in a second direction and a control unit including a processor and a memory storing instructions. The processor may be configured to execute the instructions to: generate a first 3D model of an environment; generate a plurality of revolved 3D models by revolving the first 3D model relative to the image sensor to a plurality of positions within a predetermined angular range; match a set of distance values to one of the revolved 3D models; determine an angular position of the second direction relative to the first direction; and generate a 3D reconstruction of the environment.

Abstract: The present disclosure provides computer vision systems and methods for an aircraft. The computer vision systems and methods identify a runway based on video frame data from a camera mounted to the aircraft, extract runway pixel positions associated with the runway, determine the aircraft position in a real world coordinate frame based on the pixel positions, the aircraft position including an aircraft lateral position and an aircraft elevation, receive predefined aircraft position data and go-around rules for a compliant approach to the runway, calculate an aircraft position deviation based on the aircraft position and the predefined aircraft position data, determine whether the aircraft position deviation is in conformance with the go-around rules, and output an indication of conformity with the go-around rules.
