针对图像指纹特征，提出一种图像指纹识别定位原理，首先对图像采用高阶曲面拟合的方法，得到图像边缘检测结果，然后利用网格搜索的随机hough变换法识别出圆形指纹特征，最后，依据图像地理先验知识，获取图像位置，得到目标定位。仿真实验结果表明，此方法能够准确的对图像指纹进行识别定位，即准确计算出它在图像中的位置及大小，并为图像目标识别提供了一种可行有效的方法。
針對圖像指紋特徵，提齣一種圖像指紋識彆定位原理，首先對圖像採用高階麯麵擬閤的方法，得到圖像邊緣檢測結果，然後利用網格搜索的隨機hough變換法識彆齣圓形指紋特徵，最後，依據圖像地理先驗知識，穫取圖像位置，得到目標定位。倣真實驗結果錶明，此方法能夠準確的對圖像指紋進行識彆定位，即準確計算齣它在圖像中的位置及大小，併為圖像目標識彆提供瞭一種可行有效的方法。

A principle of image fingerprint identification and location is put forward in accordance with the features of image fingerprint.Firstly,an approach of higher order surface fitting is taken to obtain the image edge detection result.Next the randomized Hough transform method of the grid-search is exploited for the identification of round fingerprint features.Then the image position is got on the basis of prior knowledge of geographic pattern,and the target is finally located.The simulation result shows that an accurate identification and location of image fingerprint can be achieved through this method,which can calculate its position as well as size in the image and makes the image target identification and location feasible and efficient.
