摘要: 遥感技术的发展使得遥感影像被应用于农业、军事等诸多领域,而深度学习方法的融入使得该项技术在目标检测、场景分类、语义分割方面取得了重大突破。与自然场景下的舰船检测不同,遥感图像中的舰船为俯视图,舰船较为密集,且容易与港口混合。当前对舰船检测的输出结果主要是检测框,缺少对舰船掩码的输出,使得无法全面分析出模型存在的不足;同时,由于遥感图像中的舰船停靠密集,容易产生漏检问题。为解决上述问题,利用Mask R-CNN对舰船进行目标检测,较全面地分析模型的训练情况、掩码和检测框的输出结果;通过对目标边缘的学习及参数的调整,使模型与舰船目标相适应。通过实验分析得出了适用于舰船检测的网络模型参数,从而有效降低了舰船停靠密集所产生的误检和漏检问题。
