Abstract:
Depth map of an image provides information about the distance of the objects in the image to the stereoscopic camera. This information is widely employed in three dimensional visualization of stereoscopic images. Depth map of an image can be evaluated by calculating the disparity values of objects in the image. Disparity is the planar difference between corresponding points in an image pair, captured by a stereoscopic camera. In this work, we propose a fast and accurate method for evaluating the disparity values of images captured by a digital stereoscopic camera system. The stereovision system, evaluating the disparity values, runs on a field programmable gate array chip and uses an off the shelf stereo camera module to capture stereo images. The disparity values, evaluated by the system, show good match with the theoretical values.
