摘要: 互联网与电子商务的高速发展带来了物流业的颠覆性变革,但目前我国物流业存在总成本偏高、技术装备偏低、配送系统效率低下的缺点。长久以来,物资的几何尺寸信息的利用在物流行业中处于薄弱环节,有效利用几何尺寸信息将极大程度地改善物流业的包装、分拣以及分类运送等环节。基于此,设计了物流业物资的几何尺寸测量系统,该系统基于双目视觉系统,将视差法三维重构算法与特征提取及定位算法紧密结合,能够在复杂场景下对一般物流业物资进行现场测量,且受光照影响较少。测量系统的关键环节是目标物体特征的提取以及几何尺寸的测量。实验结果表明,几何尺寸的平均测量误差小于2%,最大误差小于3%,能够满足物流业的基本要求,可使之更加快速和智能。
