Abstract: Un método que comprende: realizar el seguimiento (202) de una pose relativa entre una cámara (108) y un objetivo (101) utilizando una contribución de mediciones de sensor inercial y una contribución de mediciones basadas en visión, estando basadas las mediciones basadas en visión en imágenes del objetivo (101) capturado por la cámara (108); en donde la contribución de las mediciones de sensor inercial es una contribución ponderada y la contribución de las mediciones basadas en visión es una contribución ponderada; detectar (204) movimiento del objetivo (101); y reducir (208) la contribución ponderada de las mediciones de sensor inercial para realizar el seguimiento de la pose relativa entre la cámara (108) y el objetivo (101) cuando se detecta movimiento del objetivo (101); el método caracterizado por que la ponderación de la contribución de las mediciones de sensor inercial se varía en función de una confianza en la detección de movimiento del objetivo.

Abstract: A mobile device tracks a relative pose between a camera and a target using Vision aided Inertial Navigation System (VINS) that includes a contribution from inertial sensor measurements and a contribution from vision based measurements. When the mobile device detects movement of the target the contribution from the inertial sensor measurements to track the relative pose between the camera and the target is reduced or eliminated. Movement of the target may be detected by comparing vision only measurements from captured images and inertia based measurements to determine if a discrepancy exists indicating that the target has moved. Additionally or alternatively movement of the target may be detected using projections of feature vectors extracted from captured images.

Abstract: Embodiments disclosed pertain to the use of user equipment (UE) for the generation of a 3D exterior envelope of a structure based on captured images and a measurement set associated with each captured image. In some embodiments, a sequence of exterior images of a structure is captured and a corresponding measurement set comprising Inertial Measurement Unit (IMU) measurements, wireless measurements (including Global Navigation Satellite (GNSS) measurements) and/or other non-wireless sensor measurements may be obtained concurrently. A closed-loop trajectory of the UE in global coordinates may be determined and a 3D structural envelope of the structure may be obtained based on the closed loop trajectory and feature points in a subset of images selected from the sequence of exterior images of the structure.
