Reconstruction of three-dimensional stereo objects from multi-aspect high-resolution SAR images is of great importance for SAR technology applications. In this paper, a building object is simply modeled as a cuboid, and automatic reconstruction of three-dimensional (3D) objects from multi-aspect metric-resolution SAR images is developed. In Part I, a method for building image extraction from metric-resolution SAR image is studied. The edge detector of constant false alarm rate (CFAR) is first employed to detect the edge of polarimetric SAR image. Due to the linear feature of building images, parallel Hough transform technique is introduced to further extract the parallelogram-like images of the building wall scatterings. Image extraction is successfully performed using both simulated image and X-band Pi-SAR images. Reconstruction of building objects from their multi-aspect images will be discussed in Part II.
