摘要
为检测填料板的波峰高度、平均波间距等参数,提出了一种基于线结构光的填料板尺寸测量系统.首先,介绍了系统的组成及基于激光三角法的测量方案,对测量系统进行标定,获取了相机成像模型与被测物之间的坐标转换关系;然后,利用改进的灰度重心法对线激光的光条中心进行提取;最后,对采集的点云数据沿y轴切片,分别对多组切片上的点集进行拟合,从而完成波峰高度和平均波间距的测量.实验结果表明,使用的改进的光条中心提取法精度更高,波峰高度测量误差可达±0.04 mm,平均波间距的测量误差可达±0.08 mm,满足实际生产需求.
Abstract
In order to detect the peak height and average wave spacing of the packing board,a size measurement system based on line structured light is proposed.Firstly,the composition of the system and the measurement scheme based on the laser triangle method were introduced,calibrated the measurement system,obtained the coordinate con-version relationship between the camera imaging model and the measured object.Then,extracted the center of the line laser stripe by the improved gray-gravity method.Finally,the collected point cloud data was sliced along the y-axis to fit points on multiple sections to complete peak height and average wave spacing measurement.The experimental re-sults show that the improved light bar center extraction method has higher accuracy,the measurement error of peak height can reach±0.04 mm,and the measurement error of average wave spacing can reach±0.08 mm,which meets the actual production needs.
