Abstract
An optical passive stereo assembly for generating a three-dimensional image, the optical assembly comprising: two image capturing devices each mounted within the optical passive stereo assembly in a skewed position to the other with respect to the horizontal plane; a processor configured to: process data retrieved from a plurality of pixels comprised within images captured by the two image capturing devices, and generate a point cloud, being a set of data points in a 3D space retrieved from the tilted coordinate system (X′, Y′, Z′); apply a 2D rotation in the X-Y plane to the point cloud, thereby converting the coordinate system of the resulting point cloud to a conventional cartesian coordinate system (X, Y, Z), to enable generating the three-dimensional image.
