Studied on Agricultural Visual Navigation Tilt of the Image Correction Based on the MATLAB

摘要

Agricultural machinery automatic navigation is a very important part of modern intelligent agricultural machinery with broad development prospects. Because of the influence of the rough ground, farm machinery automatic navigation vehicles of image collection could produce certain angle, causing the error of the navigation parameters extraction of the later. To improve the accuracy of the navigation parameters, the phase correlation law was put forward based on log-polar transform;Images were transformed from a Cartesian coordinate system to the log-polar coordinate, and corrected by image registration. The experimental results showed that the method could be rapid, effective to correct angle of the image.
