Abstract:
A method is provided for obtaining a disparity map for reconstructing a three dimensional image. The map is based upon a large range of disparities and is obtained by using a hardware provided with a buffer capable of storing data that relates to substantially less disparities than a data associated with the large disparities' range. The method comprises the steps of: providing a pair of stereoscopic images captured by two image capturing devices; dividing the large disparities' range into N disparity ranges; executing a stereo matching algorithm for a plurality of times, using data retrieved from a pair of captured images, wherein the algorithm is executed each time while using a different disparity range out of the N disparity ranges, thereby obtaining a plurality of individual disparity maps, each corresponding to a different disparity range; and merging the individual disparity maps to generate a map of the large disparities' range.
Abstract:
A method and apparatus are provided for generating a three dimensional image. The method comprises: illuminating a target; capturing an image that comprises an object present at the illuminated target; converting the captured image into data and processing it to determine depth of the object; and generating a three dimensional image of the object whose depth has been determined. Preferably, the illumination intensity applied while illuminating the target, is determined based on the current intensity of ambient light at the target.
