| 摘 要： | 针对圆标记中心的高定位精度要求,提出一种新的基于空间矩的亚像素定位算法。建立了基于空间矩的圆曲线亚像素边缘检测算法,并用最小二乘边缘拟合算法来获取圆标记中心的亚像素位置,克服了基于传统的Lyvers空间矩算法进行圆标记中心定位存在的误差大的缺点。仿真对比实验表明该算法相对于其他算法具有更高的精度。

| Abstract: | To meet the requirement of high location precision for circle target center,a novel subpixel location algorithm based on spatial moment was proposed.A spatial moment based algorithm was developed to detect the edge of a circle,and the subpixel location of circle target center was determined using the least mean-square fitting algorithm.It overcomes the large error shortcoming of traditional Lyvers spatial moment algorithm in locating circle target center.Comparing simulation results show that the precision ... |
