Based on the theory of epipolar slope matching, this paper proposes a new method of rapid ambiguity\|avoiding feature matching which can be used to solve the problem of ambiguity in matching effectively considering the trait of the inspection system of multi\|view stereo vision.

The calculation and analysis indicate that the influence of polarization channel amplitude unbalance error on target polarization matchingis most important, and across polarization interference is also important.

Under tested analysis for the different polarization conditions of source antenna,It shows that antenna polarization matching should be carefully considered.

Traditional maximal matching(MM) algorithm cannot get a proper balance between these two factors,so in this paper we propose a new kind of Extended Maximal Matching(EMM) algorithm.

Several representative maximal matching algorithms such as PIM,iSLIP,FIRM and Output Serial Polling are studied in this paper.

For the films prepared at 650 ℃, their RHEED pattern observed along the direction of Al2O3 [11–20] exhibits as clear spots, indicating that the growth mode of these films is island-by-island mode and the epitaxial matching relationship between such films and sapphire substrates is (111)[11–2] NiO // (0001) [11–20] Al2O3.
