| Abstract(in English) | In this paper, we describe an approach for estimating the orientation of a signboard relative to the camera from a single view and rectifying a distorted signboard image taken from a non-orthogonal viewing direction. First, signboards in scene images are detected by using several heuristics of characters and character lines. Then, we try to compute the relative orientation of the camera and a detected signboard from a single view and rectify a distorted signboard image using two methods. Experimental results indicate the effectiveness of the proposed approach. |
