摘要: 摄像机广泛使用于公共场合及专业场景,但仅限于视频图像的捕捉,当有测距需求时,需要安装双目摄像机或其他测距设备。以变电站已安装的分散式摄像机为例,提出一种基于分散式多目视觉基线的协同测距方法,通过构建多组虚拟双目摄像机,实现对移动目标的测距。该方法利用变电站已有分散部署的高清摄像机,在已知位姿参数与基准目标的前提下,动态构建多组双目视觉测距基线,结合多视角图像的时间与空间一致性,实现移动目标的实时定位与安全距离测量。研究内容包括:多摄像机位姿参数的自标定与基线优选机制、基于双目几何约束的移动目标深度估计、融合语义分割的目标关键点匹配策略,以及多基线协同测距的加权融合算法。在实验室与真实变电站场景下的实验结果表明,所提方法能够在低算力边缘设备上实现厘米级测距精度,显著优于传统单基线双目系统,具有良好的工程适用性与推广价值。
