Vanishing Point Detection
Commencing with a review of methods for vanishing point (VP) detection, a new approach is suggested. The proposed approach estimates the location of candidate vanishing points and provides probability measures which reflect the likelihood of those points being the VPs. This new approach allows VPs to be identified in less structured environments compared with its conventional counterparts.
متن کاملVanishing Point and Vanishing Line Estimation with Line Clustering
In conventional methods for detecting vanishing points and vanishing lines, the observed feature points are clustered into collections that represent different lines. The multiple lines are then detected and the vanishing points are detected as points of intersection of the lines. The vanishing line is then detected based on the points of intersection. However, for the purpose of optimization, ...
متن کاملAn Optimised Vanishing Point Detector
In this paper we use line segments from a Hough transform algorithm to locate vanishing points in an image. The line parameters have already been determined to high accuracy, and the purpose of this paper is to present a scheme for locating the vanishing points from the line intersections which takes full advantage of this accuracy. We present a natural generalisation of the usual accumulator m...
متن کاملVanishing Point Detection in Urban Scenes Using Point Alignments
We present a method for the automatic detection of vanishing points in urban scenes based on finding point alignments in a dual space, where converging lines in the image are mapped to aligned points. To compute this mapping the recently introduced PClines transformation is used. A robust point alignment detector is run to detect clusters of aligned points in the dual space. Finally, a post-pro...
متن کاملVanishing Point Detection with an Intersection Point Neighborhood
A new technique to automatically detect the vanishing points in digital images is presented. The proposed method borrows several ideas from various papers on vanishing point detection and segmentation in sparse images and recombines them with a new intersection point neighborhood on Z.
