摘要
海天线是海空背景图像所具有的重要特征之一,海天线的检测对天空区域和海面区域的划分以及目标检测具有重要作用。然而,复杂海空背景环境中的海杂波、云层、强反射、复杂气象条件等都会给海天线检测造成困难。针对复杂背景下海天线检测的环境适应性问题,对视觉传感器获取的原始图像及图像中海天线的特点、干扰因素及其抑制方法、现有的海天线生成方法三个方面进行了详细的阐述和分析,通过对比实验列出各种海天线生成方法的优缺点和适用场景,对比分析了自行提出的形态学方法的实验结果及适用场景。最后提出海天线检测面临的挑战,展望其下一步的研究方向。
Abstract
The sea-sky line is an important feature of sea and air background images, and its detection plays an important role in the division of sky and sea areas and target detection. However, sea clutter, clouds, strong reflection, and dynamic weather conditions in the complex sea and air background environment make it difficult to detect the sea-sky line. This paper aims to address the environmental adaptability problem of sea-sky line detection in a complex background. Three aspects were analyzed in detail: the characteristics of the original image obtained by the visual sensor and those of the sea-sky line in the image; interference factors and their suppression methods; existing methods of generating the sea-sky line. Furthermore, their advantages, disadvantages, and applicable scenarios were elaborated through comparative experiments, and the proposed morphological methods were experimentally compared. Finally, the future challenges and research directions of sea-sky line detection were discussed.
