摘　　要：传统的基于相关的匹配方法计算量相当大,而且当模板相对于搜索图有角度旋转时,匹配的计算量更大。用圆投影和Zernike矩的方法对快速的且具有旋转不变性的模板匹配方法进行了研究,圆投影将图像由二维变换成一维,这样就降低了计算复杂度,通过相似性度量可进行快速地粗匹配,然后在可能的匹配点中,再用Zernike矩实现精匹配。The computation of conventional cross-correlation type algorithms is expensive. Furthermore, when the template rotate relative to the image, the amount of computation with conventional algorithms is larger. An algorithm for a rotation invariant template matching method based on the combination of the circle projection method and Zernike moments is researched. By making circle projection, Image can be transformed to one dimension from two dimensions, thus computational complexity is reduced and fast coarse matching is also processed by cross-correlation measure. Then accurate template matching is performed only on the matching candidates using Zernike moments.
