摘要:
针对工业现场中相机因补料装置限制而无法正对料仓安装的难题,提出一种基于结构光3D相机倾斜拍摄的料仓物料体积检测方法。首先,通过建立倾斜坐标系下的3D重建数学模型,并利用三角测量原理和相位解算技术获取物料表面点云;其次,设计一种空间坐标预测方法,有效修复点云中的空洞区域;最后,构建差分体积算法,通过空仓与含料仓点云的差值精确计算物料体积。实验结果表明:在30°~60°倾斜角度下,文中方法体积检测的相对误差控制在2.5%以内,且不受料仓形状和尺寸的影响。
Abstract:
To address the challenge in industrial settings where cameras cannot be installed directly facing silos due to constraints of material replenishment devices, a material volume detection method for silos based on tilted imaging using structured light 3D cameras is proposed. Firstly, a 3D reconstruction mathematical model under tilted coordinates is established to obtain surface point clouds by the triangulation principle and phase unwrapping technology. Secondly, a spatial coordinate prediction method is designed to effectively repair the hollow region of the point clouds. Finally, a differential volume algorithm is constructed to accurately calculate the material volume through the difference between the point clouds of the empty silo and the silo with materials. The experimental results show that at tilted angles from 30° to 60°, the relative error of volume detection of the proposed method is controlled within 2.5%, and it is not affected by the shape and size of the silo.
