针对某基地提出的基于机器视觉的火箭跟踪伺服系统对火箭目标分割提取的要求,提出了带有衰减因子的Prewitt边缘检测算子与改进的最大类间方差法相结合的图像分割方法.根据火箭的形态特征提出了一种带方向非线性滤波去噪法,对分割后所得到的图像做了进一步去噪处理,除去了与火箭形态无关的边缘.仿真实验表明,采用该方法对火箭目标正确分割率为96.5%,并能够实时有效地对火箭序列图像进行有效分割.
針對某基地提齣的基于機器視覺的火箭跟蹤伺服繫統對火箭目標分割提取的要求,提齣瞭帶有衰減因子的Prewitt邊緣檢測算子與改進的最大類間方差法相結閤的圖像分割方法.根據火箭的形態特徵提齣瞭一種帶方嚮非線性濾波去譟法,對分割後所得到的圖像做瞭進一步去譟處理,除去瞭與火箭形態無關的邊緣.倣真實驗錶明,採用該方法對火箭目標正確分割率為96.5%,併能夠實時有效地對火箭序列圖像進行有效分割.

To satisfy machine vision based rocket tracking servo system's requirements for rocket target segmentation, a segmentation method combined with Prewitt edge detection operator with decaying factor and improved Otsu algorithm was proposed. Based on the rocket's morphological characteristics, a nonlinear filter de-noising method was presented to denoise and remove the non-rocket edge. Simulation results show that the proposed method has 96.5% successful segmentation rate for rocket target, and can effectively segment rocket image sequence in real-time.
