A method of generating a three-dimensional representation of an environment from stereo image data 302 comprises: selecting 308 a set of feature points in each image, calculating the stereo disparities between the points, joining 310 the points in each image to form a polygonal mesh for each image, and using the disparity between corresponding points to determine 312 the plane parameters for the image. The method may be used in an advanced driving system comprising stereoscopic pair of cameras. A second method of processing stereo image data comprises: using stereo matching to generate a 3D representation of the environment for object detection, using the representation to determine a transformation to be applied to the first image or the second image such that distant portions of the image are expanded and near portions are shrunk. A further method of processing stereo image data for application in an object detection system comprises: using stereo matching to produce a 3D representation, and determining, using the 3D representation, one or more 2D region of interest where each of the regions of interest is associated with a portion of the generated 3D representation.
