胶囊内窥镜技术是胃肠道内窥镜检查的一个重大突破,但其临床反馈尚有一些问题待解决,其中一个问题就是定位跟踪。在各种可能的定位技术中,磁体定位技术具有不用供电且体积小等特点,应用于胶囊内窥镜的定位问题是非常合适的。文章针对磁体定位技术中的磁偶极子定位模型,提出一种新的算法--混合人工蜂群算法,并将该算法与标准人工蜂群算法、随机复合形算法、Levenberg-Marquart(LM)算法进行对比。实验结果表明,混合人工蜂群算法在算法定位精度、算法稳定性和抗噪能力等方面,比其他三种算法具有更优越的性能。
膠囊內窺鏡技術是胃腸道內窺鏡檢查的一箇重大突破,但其臨床反饋尚有一些問題待解決,其中一箇問題就是定位跟蹤。在各種可能的定位技術中,磁體定位技術具有不用供電且體積小等特點,應用于膠囊內窺鏡的定位問題是非常閤適的。文章針對磁體定位技術中的磁偶極子定位模型,提齣一種新的算法--混閤人工蜂群算法,併將該算法與標準人工蜂群算法、隨機複閤形算法、Levenberg-Marquart(LM)算法進行對比。實驗結果錶明,混閤人工蜂群算法在算法定位精度、算法穩定性和抗譟能力等方麵,比其他三種算法具有更優越的性能。

The technology of the capsule endoscope for the detection of the gastrointestinal disease has made a major breakthrough. But the clinical feedback show that some problems are to be solved, including the problem of the location and tracking. Among the possible localization technologies, the magnetic positioning technology with advantages of no need for power and not much space occupation and so on, is very suitable to be applied to the problem of localization of the capsule endoscope. In this paper, for the positioning model of the magnetic dipole based on the magnetic positioning technology, a new algorithm -- hybrid artiifcial bee colony algorithm was proposed and compared with the artiifcial bee colony (ABC) algorithm and the nonlinear optimization algorithms that the random complex algorithm and the levenberg - marquart (LM) algorithm. The experimental results show that in terms of the positioning accuracy, the stability and the anti-noise ability, the hybrid artiifcial bee colony algorithm has better performance than the other three methods.
