Abstract: Provided herewith a computer-based method for assessing a location of an object-of-interest (OBIN) in a building site. The method may comprise: acquiring an image of an OBIN captured by an image capturing device (ICD) within the building site; acquiring a position and orientation of the ICD at the time the image was captured; processing the image to identify an observed reference point of the OBIN on the image; and determining spatial coordinates for the observed reference point with respect to the model. Alternatively, the method may comprise: acquiring an image of a building site captured by an ICD; acquiring a position and orientation of the ICD at the time the image was captured; determining an expected position on the image for an object based on a model of the building site; determining an image-based-position of the object; and detecting a discrepancy between the expected position and the image-based position.

Abstract: A method for determining a position of an image capture device (ICD) within a building site, the module comprising: registering an image captured in the building site by the ICD; registering an initial ICD position of the ICD at the time the image was captured; generating a plurality of proposed ICD positions based on the initial ICD position; and selecting an optimized ICD position from the plurality of proposed ICD positions. Optionally, the optimized ICD position is selected responsive to a model of the building site that comprises sufficient information to generate a three dimensional (3D) representation of the building site.
