Improved orientation estimation for texture planes using multiple vanishing points
2000
Pattern Recognition
Preserved Fulltext
In this paper we describe a method for multiple vanishing point and, hence complete perspective pose estimation, which obviates the need to compute the texture gradient. ...
Vanishing point locations play a critical role in determining the perspective orientation of textured planes. However, if only a single vanishing point is available then the problem is undetermined. ...
We will exploit this property to develop a geometric algorithm for recovering the image-plane position of the vanishing-point, and hence, for estimating the orientation of the texture-plane. ...
