摘要
结合基于锚点的质心算法定位精度高和与锚点无关的ABC算法成本低优点,提出了一种改进算法,即连通度阈值与三角面积结合算法.在减少质心算法锚点数目的情况下控制ABC算法的误差在可接受的范围内,从而满足实际应用对精确度的要求.最后讨论了使用改进算法需要注意的两方面因素和如何根据实际应用进行选择.
The anchor- based mass algorithm has higher precision while the anchor-free ABC algorithm has lower cost. In order to take advantages of them, a new localization algorithm is presented. It not only controls the precision within endure ranges of ABC algorithm, but also reduces the number of anchors of the mass algorithm. So it can meet the needs of the actual applications. In the last, the attentions of the new localization algorithm is indicated.
