| 摘 要： | 针对发射场火箭初始段漂移量的测量，提出一种带灰度梯度方向的SUSAN算子，实现了基于该算子与变模板相关跟踪算法的目标跟踪测量方法.首先在SUSAN特征检测原则的基础上，将对角点的检测转化为对边缘的检测，同时记录梯度方向，在剔除了图像噪音点之后，由具有特定方向信息的边缘像素点精确定位角点的坐标.该方法克服了标准SUSAN算法准确度低的弊病，使得对目标的提取准确度可以达到亚像素级，并增强了抗噪性能，实验证明该算法提取准确性高，运算量小，易于实现. |

| Abstract: | A new algorithm to measure the drift of rockets in the initial launching stage is presented and developed.It is designed to combine the improved SUSAN detector and the correlation.In this method,the corner detector is improved to detect the edge.Meanwhile,the direction of Gradient is recorded.After filter,the coordinates of corners are calculated accurately by using the edge pixels with special direction.The precision and the anti-noise performance is improved by this method.The results show that the precision reaches sub-pixel,with few mistake in detecting,and this algorithm is easy to realize for its less operations. |
| Keywords: | Drift quantity measurement Target tracking SUSAN Corner detector Correlation |
