摘　　要：针对成像声呐的水下目标检测问题,提出一种改进的snake目标轮廓提取方法。该方法首先通过构建高斯模型对成像声呐进行目标检测,提高了目标检测能力。其次根据预设目标粗略区域,结合梯度矢量流(GVF)改进的snake算法,实现了目标轮廓的连续提取。仿真试验验证了所提方法的有效性。An improved snake target contour extraction method is proposed for the underwater target detection problem of imaging sonar.The method firstly improves the target detection capability by constructing a Gaussian model for imaging sonar for target detection.Secondly,the snake algorithm is improved according to the preset target rough region,combined with the gradient vector flow GVF to achieve continuous extraction of target contours.The effectiveness of the proposed method is verified by simulation tests.
