Abstract Preview model Parameters Evaluation RANSAC algorithm (PERANSAC) is given in vanishing point detecting. A preview model parameters evaluation selection is added in the RANSAC algorithm. With guaranteeing the same confidence of the solution as RANSAC, a very large number of erroneous vanishing point obtained from contaminated samples are discarded in the preview evaluation selection. The time of evaluating the quality of the vanishing point is reduced. RANSAC efficiency is significantly improved. PERANSAC algorithm is evaluated on real-world images, a significant increase in speed is shown and the solutions are same as RANSAC.
