SYSTEM AND METHOD FOR RECONSTRUCTION OF RANGE IMAGES FROM MULTIPLE TWO-DIMENSIONAL IMAGES USING A RANGE BASED VARIATIONAL METHOD

摘要

Reconstruction of range images from multiple two-dimensional images uses 2D images of a scene, defining a reference 2D image and then defining an initial generated range image associated with the reference 2D image. The initial generated range image includes depth information for at least a portion of the pixels of the reference 2D image. A cost-functional is provided to calculate a cost reflecting how well the generated range image matches a set of criteria. Each criterion is evaluated as a cost sub-functional of the cost-functional, together with a factor that reflects the criterion's importance to the overall cost. A variational method is used to find an optimal generated range image in regards to this cost. The variational method includes repeatedly updating the generated range image and re-calculating the cost using the cost-functional until a given stopping criterion is reached.
