In this paper, we propose “Orthographic Projective Grid Space (OPGS)” defined by two orthographic uncalibrated cameras. We also describe the methods to reconstruct the object in the space and generate the arbitrary view images without camera calibration. The coordinate system of OPGS is more similar to the one of Euclid space than the coordinate system of Projective Grid Space, in which the shape of the objects can be reconstructed without camera calibration. We use Silhouette Intersection method with octree data structure to make the reconstruction time faster. Additionally, we also describe the experiments and the evaluations about the space for demonstrating the effectiveness of the proposed OPGS. We can reconstruct the object as polygon model in the space and it looks like the models in Euclid space.
