VanishingPointDetection

2-Line Exhaustive Searching for Real-Time Vanishing Point Estimation in Manhattan World,Xiaohu Lu, JianYao, Haoang Li, Yahui Liu and Xiaofeng Zhang, WACV2017.

http://xiaohulugo.github.io/papers/Vanishing_Point_Detection_WACV2017.pdf

Prerequisites:

OpenCV > 2.4.x

Usage:

  1. build the project with Cmake
  2. set the internal parameters of the input image (it's ok to use approximate values, for example: pp(cols/2,rows/2), f=1.2*max(cols,rows), but the result will be a little worse)

Performance:

40ms on a computer with Intel Core i5-3550p CPU without any optimization and parallel computation in the Release mode.
