ABSTRACT:
In accordance with a specific embodiment of the present invention, an image is projected upon a surface. The image can include a pattern having a plurality of individual shapes used to measure and map the surface. The plurality of individual shapes include features that are detectable in a direction parallel to the plane formed by a projection axis of the projected shapes and a point associated with a view axis. The image further comprises a feature containing an encoding information for identifying the plurality of shapes individually. The feature containing encoding information can be a separate feature from each of the plurality of individual shapes, or may be a feature integral to the plurality of individual shapes. The feature containing encoding information is oriented such that the encoding information is retrieved along a line perpendicular to a plane formed by the projection axis and the point along the view axis. The use of the feature is used to perform multiframe reference independent scanning.
