| 摘 要： | 提出将图像的灰度用三维曲面表示,并作各剖面得到灰度截面曲线,再作差分运算得到灰度截面差分曲线,来描述图像特征。并依此方法比较车牌图像各个区域,进行车牌定位。

| Abstract: | A idea is put forward that grey-level of picture is showed with three-dimensional curved surface, some section planes aremade to get grey-level sectional curves, distinction operation is made to get grey-level sectional distinction curves, image characteris described by them. Every area of license plate image is compared to locate license plate with these methods. |
