Method and system for object reconstruction

摘要

A system and method are presented for use in the object reconstruction. The system comprises an illuminating unit, and an imaging unit (see FIG. 1). The illuminating unit comprises a coherent light source and a generator of a random speckle pattern accommodated in the optical path of illuminating light propagating from the light source towards an object, thereby projecting onto the object a coherent random speckle pattern. The imaging unit is configured for detecting a light response of an illuminated region and generating image data. The image data is indicative of the object with the projected speckles pattern and thus indicative of a shift of the pattern in the image of the object relative to a reference image of said pattern. This enables real-time reconstruction of a three-dimensional map of the object.

1. A system for object reconstruction, comprising:
an illuminating unit, comprising a coherent light source and a generator of a random pattern comprising a diffractive optical element (DOE) in an optical path of illuminating light propagating from the light source toward an object, thereby projecting the random pattern onto an object; an imaging unit configured to detect a light response of an illuminated region and generating image data indicative of the object within the projected pattern; and a processor, configured to reconstruct a three-dimensional (3D) map of the object responsively to a shift of the pattern in the image data relative to a reference image of the pattern.
