A method for three-dimensional imaging is provided, storing a first two-dimensional image of field of view of a scanning device at a first position where a first three-dimensional view of the object is captured with said handheld scanning device； estimating location metric of a second two-dimensional image of field of view of said scanning device at a second position relative to said first image while said scanning device is being moved from said first position to said second position； and generating instructions on providing feedback to the user based on said location metric； wherein said feedback is provided to indicate if said second position is adequate for capturing a second three-dimensional view. A system for three-dimensional imaging is provided as well.
