摘要
运用基于数字图像处理技术进行高炮武器系统射击诸元校正工作中,弹目偏差的确定是校射的关键,而确定弹目偏差的关键步骤之一是需要对弹目图像进行边缘检测,提取弹丸和目标的边缘特征。在综合分析典型边缘检测算法的基础上,提出运用基于迭代阈值的边缘检测算法进行弹目图像边缘求取,并分析了迭代法确定最佳阈值的步骤,给出了迭代阈值边缘检测算法工作流程,最后通过仿真实验表明基于迭代阈值的边缘检测算法具有良好的边缘检测效果,是一种有效的弹目图像边缘检测算法。
In the process of antiaircraft artillery weapons system shooting amending based on digital image processing technique,the determination of miss distance is the key of shooting amending.One of the key steps of determining miss distance is to make the edge detection for projectile and target＇s image and pick up the projectile and target ＇s edge features.Based on the comprehensive analysis of typical edge detections algorithms,the paper proposes an edge detection algorithm based on iterative threshold to obtain projectile and target＇s image edge features,analyses the steps of determining the optimal threshold value,and illuminates the workflow of iterative threshold edge detection algorithm.The simulation results show that the iterative threshold edge detection algorithm has a good edge detection result.It is an effective projectile and target＇s image edge detection algorithm.
