A method for estimating three-dimensional depth value from two-dimensional images

The present invention relates to a method for estimating three-dimensional depth value from two-dimensional images, characterised by the steps of placing an object (102) on a rotatable plate (103); acquiring a first view of the object (102) comprising a first image and a second image of the object (102), wherein the first image of the object (102) is captured at an angle between 0° to 360°, and the second image is captured at an angle in a range of 1° to 35° relative to the first image; obtaining two-dimensional feature point coordinates by applying Good Features to Track technique and extracting colour information, simultaneously, from the first image and the second image; filtering two-dimensional feature point coordinates; applying Pyramidal Lucas-Kanade Optical Flow technique to obtain displacement magnitudes from the two-dimensional feature point coordinates; calculating World Coordinate; estimating the three-dimensional depth value of the acquired images; and implementing inverse perspective mapping algorithm on the three-dimensional feature point coordinates.
