Abstract: Low　altitude 　image　matching　with　re peated 　texture　may　have　a　small　amount　of 　corresponding　points 　or 　beunsuccessful 　because　of 　ambiguous　matching．To　solve 　the　problem aphase　correlation　method　supportes 　low　altitude 　aerial 　image　matching　with　re peated 　texture 　is 　proposed．The method　estimates 　the 　traversal 　range　of 　corresponding　points including　translation rotation and scale 　space．The 　traversal 　range　is 　estimated　by　a　cross －power　spectrum　of 　the 　image　Fourier　transform　and　a　complex 　con jugate 　of 　another 　image　Fourier　transform．Next Harris－Laplace 　scale 　space 　is estimated　by　the 　scale 　traversal 　range　and　corners　detection．Thencorresponding　point　matching　is 　a chieved　by　a　correlation　coefficient 　and　epipolar 　constraint．The 　experimental 　results 　show　that 　the method　may　be 　reliable 　and　practical 　for 　low　altitude 　images　matching　with　a　re peated 　textureand　obtains 　enough　and　well－distributed 　corresponding　points．
