Relationship between view angle and distance between parallel edges with vanishing point in 2D images

Abstract

A vanishing point is one of the possibly several points in a 2D image where lines that are parallel in the 3D source converge. Vanishing point provides a lot of information in most of the applications like distance of objects in 3D Scene. This point depends on camera viewing angle as well as distance between the parallel edges in a scene. In order to find the relationship between the vanishing points with view angle and distance between parallel edges, various data were collected by having an experimental setup by varying the distance between two parallel sticks in an image and also by varying the angle of the camera with the parallel sticks. Different data mining techniques were used, and the results were found in two phases. The results of regression model for the relationship between the angle of the camera and the X and Y coordinates of the vanishing point have been analyzed using neural network model, which gave 100 % validity on the model. © 2014 Springer India.
