Abstract: A method for determining an optimal location for positioning an image capturing device within a volume, the method including, obtaining a plurality of points to be visible from the image capturing device, performing inversion on points located in the vicinity of the plurality of points thus creating a computerized inversed object, each point in the vicinity of the plurality of point is translated to a corresponding point in the computerized inversed object, defining a convex hull of the inversed object, determining if a point of the plurality of points is visible from the viewpoint according to the position of its corresponding point on the convex hull relative to its neighbor points, repeating said determining for multiple locations within the volume, determining whether a predetermined set of points is visible from each location, selecting the optimal location of the image capturing device based on the results of said repeated determining.
