Study on measurement of cut tobacco stacking volume based on TOF LiDAR Scanning
摘要
Abstract
[Objective]This study aims to explore the application prospects of online measurement of cut tobacco stacking volume using TOF LiDAR scanning.[Methods]An online measurement system for cut tobacco stacking volume on a conveyor belt was independently developed.The study investigated the effects of TOF LiDAR scanning height,conveyor belt color,and operating speed on the system.Additionally,a 2.5D volume calculation was performed on the cut tobacco point cloud processed by the algorithm.[Results]The results showed;1)The measurement height of the LiDAR significantly affects the proportion of outliers in the detected point cloud.Point cloud data scanned at a height of 1200 mm are more suitable for measuring the stacking volume of cut tobacco on the conveyor belt.When the conveyor belt color is white,the measurement error of the TOF LiDAR distance to the conveyor belt is minimized.Within the conveyor belt operating speed range of 40～130 mm/s,the amount of point cloud data has little impact on the reconstruction of the material scanning contour.2)During the variation of LiDAR scanning measurement height,"gaps"may occur.Using the interpolate mode to perform interpolation on missing values during volume calculation can fill the gaps,effectively improving the accuracy of the measurement results.3)The average relative error of the accumulation volume measurement of conveyor belt materials based on TOF LiDAR scanning is less than 3.0％,which well verifies that the online measurement system has high measurement accuracy.[Conclusion]Using TOF LiDAR scanning for online measurement of cut tobacco stacking volume is highly feasible and accurate.关键词
