Block-based Vanishing Line and Vanishing Point Detection for 3D Scene Reconstruction

This paper presents a robust and reliable block-based method for vanishing line and vanishing point detection. The proposed method provides assistance in construction of a depth map, which is a necessity of 3D scenes. Moreover, the method focuses on the fundamental image structural element analysis, and divides them into six successive steps. Furthermore, complicated mathematic calculation and approximation are replaced by six block-based estimation algorithms. Also, the method is a regular algorithm design which is suitable for VLSI design on future 3D applications.
