Abstract: A method and a system for simultaneous semantic mapping and investigation of a built environment are provided herein. The method may include: obtaining distance readings from a moving agent to a built environment; applying the distance readings to a semantic classifier thereby classifying a set of the distance readings into respective semantic built elements selected from a predefined list of two or more types of built elements; repeating the classifying of the distance readings until a connected set of built elements is generated, defining a built volume; detecting at least one opening in the built volume leading to a further built volume; repeating said obtaining, said applying and said classifying, until a connected set of built elements is generated, defining the further built volume; and generating a vectorial map semantically representing the built elements in each of the built volume and the further built volume, and the opening therebetween.

Abstract: Aspects of embodiments to systems and methods for navigating a mobile platform using an imaging device on the platform, from a point of origin towards a target located in a scene, and without requiring a Global Navigation Satellite system (GNSS), by employing the following steps: acquiring, by the imaging device, an image of the scene comprising the target; determining, based on analysis of the image, a direction vector pointing from the mobile platform to the target; advancing the mobile platform in accordance with the direction vector to a new position; and generating, by a distance sensing device, an output as a result of attempting to determine, with the distance sensing device, a distance between the mobile platform and the target. The mobile platform advanced towards the target until the output produced by the distance sensing device is descriptive of a distance which meets a low-distance criterion.
