Perspective distortion correction method of scene text based on vanishing point

An effective perspective distortion correction method is presented to resolve the perspective distortion correction in text recognition of natural scene. A vanishing point is detected by text baseline obtained from the tip point of text character. A vanishing point position is used to get some deformation parameters of homography matrix, which is utilized to correct the image. The front view image is achieved using a homography matrix. Compared with other methods, this method is less restricted by text layout. Experimental results show this method can effectively correct the text image with a few lines in natural scene and increase recognition rate significantly.
