The Research and Implementation of Dynamic Epipolar Rearrangement

Image re-sampling according to epipolar geometry is a prerequisite for a variety of photogrammetric tasks such as stereoscopic observation. Executing stereoscopic observation by virtue of a pair of epipolar images is a common approach. This paper proposes a new approach to generate epipolar images and measure in stereoscopic environment. In order to improve the accuracy of stereoscopic observation, a dynamic epipolar rearrangement (DER) method is presented. In this method, there is no need to construct the epipolar image pyramid, because the needed epipolar images for measurement is dynamically generated from the original stereo pair pyramid. Then scale the epipolar images and transfer it to the screen buffer directly for stereoscopic observation. The key technology and method for stereoscopic observation, such as constructing pyramid image data structure with high fidelity, dispatching image data by using multi-threaded and memory pool strategy to accelerate the speed of image display, especially the integration operation of integrating the generation of epipolar images with the transfer of the epipolar images to the screen buffer, are deeply investigated.
