Stabilization of three-dimensional images in a scannerless range imaging system
A method for generating a stabilized three-dimensional image from a scannerless range imaging system comprises the steps of acquiring a bundle of three or more phase offset images corresponding to modulated illumination reflected from a scene, whereby one or more of the phase offset images includes...

| description | A method for generating a stabilized three-dimensional image from a scannerless range imaging system comprises the steps of acquiring a bundle of three or more phase offset images corresponding to modulated illumination reflected from a scene, whereby one or more of the phase offset images includes image motion relative to another phase offset image; searching for a stable chain of phase offset images in the image bundle, wherein a stable chain is a collection of images that is obtained by testing the phase offset images against a confidence measure that separates less severe correctable image motion from more severe image motion and then populating the stable chain only with those phase offset images that meet the confidence measure for correctable image motion; correcting for the image motion in the stable chain of images if a stable chain of at least three phase offset images is found to exist; and computing a stabilized three-dimensional image using the phase offset images from the stable chain of phase offset images. |
