摘要
针对天地背景轮廓线具有波动起伏、边缘模糊及轮廓边缘灰度值变化缓慢的特点,采用灰度阈值方法,实现了多种天地背景边缘轮廓提取,可为后续的天空背景图像分割及空中目标检测提供技术支持。算法具有实现简单、计算量小、运行速度快、定位精确、抑制噪声的特点,弥补了经典图像边缘提取算法的不足,并结合远距离摄录的天空海面、天空海面岛屿、天空山地等背景的视频图像,给出了文中检测算法与其他算法的图像处理结果对比分析。
According to the characteristics of sky and earth background contour line such as fluctuation, blur？ring edge and slow change grey value of contour edge, grey threshold method is adopted to extract sky and ground background edges. It can provide technology support for subsequent sky background image segmentation and air target detection. The algorithm has the characteristics of easy to realize, few calculation, fast operation speed, preci？sion location and low noise, which compensates the shortcomings of traditional image edge extraction algorithm. With background video images recorded from long range such as sky and surface, sky, surface and island, sky and mountain, the image processing result contrast analysis of the detection algorithm and other algorithm is proposed.
