摘要: 针对低光照图像背景环境复杂导致目标检测易产生误检、漏检现象,提出了一种基于SSD目标检测的改进低光照图像精度和速度的方法。该方法先对低光照图像进行增强处理,然后将处理后的低光照图像和增强图像分别输入到融入乐高滤波器的SSD网络结构中进行训练检测,通过得到的两种检测模型对处理后的数据集进行检测,最后融合检测结果候选框中的不重复框,筛选候选框中的重复框,标记出正确位置的目标,从而提升对低光照图像检测的精度。在网络结构不同位置融入乐高滤波器,模型参数量分别减少8.9%和29.5%,浮点运算次数下降6.8%和34.9%,检测框融合处理后检测精度得到了3%~7%的提升。该方法更符合实际应用,有效提升了低光照图像的检测速度和精度,扩大了目标检测的应用范围。
