为了使轮椅机器人辅助行动不便的残疾人及老年人抓取生活中的物品,提出了基于YOLO算法和双目视觉定位结合的目标物体定位系统。首先将左右两幅图像进行校正和生成视差图,之后使用YOLOv3算法检测左图得到目标矩形框,为了避免矩形框的中心落在视差匹配错误区域造成得到的世界坐标值错误,通过对视差图的直方图分析,发现目标的视差值分布在较为集中的区域,因此,可以求取集中区域的像素点的世界坐标的均值,取平均值中的z坐标值,并利用双目原理公式反推其x,y值,最终得到目标物体中心坐标的世界坐标值。实验结果表明,该系统能

为解决视频多目标跟踪问题,提出一种特征和度量联合学习的深度神经网络架构,称为关联相似度网络。关联相似度网络以端到端的方式学习跟踪轨迹和检测结果之间的关联相似度。针对有缺陷的检测结果,关联相似度网络同时学习矩形框回归、目标分类和相似度回归3个任务。不同于现有基于对比排序思想的方法,我们直接训练一个二分类器来学习跟踪轨迹与检测结果的关联相似度,同时设计了损失函数来约束匹配集合元素的个数。得益于上述设计
