| Abstract: | According to effect of the gray distribution difference between the reference image and real-time image on matching probability,a Scene Matching Navigation(SMN) method based on histogram equalization was proposed by combining histogram modification with gray-level correlation.First,histograms were adjusted to reduce the difference of gray distribution between the reference image and real-time image.Then cross correlation was used to obtain the result of matching.The main methods for checking the scene match... |
