Commercial line laser scanners for cross-section measurement in the automotive industry predominantly employ full cross-section fitting. In scenarios characterized by strong straight-line features of double parallel cross-sections, this approach introduces redundant computation, and the closed algorithms are difficult to adapt to the dynamic optimization requirements of production lines. To address this issue, specifically for such scenarios, the Hough transform is introduced to directly detect local straight-line features, based on the camera calibration, image filtering, and laser centerline extraction techniques associated with the light-section method. While maintaining measurement accuracy, this strategy substantially reduces measurement time, achieving a profile measurement error of ≤0.15 mm for double parallel cross-sections and effectively improving the automated measurement level of car body cross-sections.

汽车行业断面测量商用线激光扫描仪多采用全断面拟合,在双平行断面的强直线特征场景下存在算力冗余,且封闭算法难以适配产线动态优化需求。为此,针对该场景,基于光切法配套的相机标定、图像滤波与激光中心线提取技术,引入霍夫变换实现局部直线特征直接检测,在保证精度的同时大幅降低测量耗时,实现双平行断面轮廓测量误差≤0.15 mm,有效提升了车身断面自动化测量水平。

汽车行业断面测量商用线激光扫描仪多采用全断面拟合,在双平行断面的强直线特征场景下存在算力冗余,且封闭算法难以适配产线动态优化需求。为此,针对该场景,基于光切法配套的相机标定、图像滤波与激光中心线提取技术,引入霍夫变换实现局部直线特征直接检测,在保证精度的同时大幅降低测量耗时,实现双平行断面轮廓测量误差≤0.15 mm,有效提升了车身断面自动化测量水平。

Commercial line laser scanners for cross-section measurement in the automotive industry predominantly employ full cross-section fitting. In scenarios characterized by strong straight-line features of double parallel cross-sections, this approach introduces redundant computation, and the closed algorithms are difficult to adapt to the dynamic optimization requirements of production lines. To address this issue, specifically for such scenarios, the Hough transform is introduced to directly detect local straight-line features, based on the camera calibration, image filtering, and laser centerline extraction techniques associated with the light-section method. While maintaining measurement accuracy, this strategy substantially reduces measurement time, achieving a profile measurement error of ≤0.15 mm for double parallel cross-sections and effectively improving the automated measurement level of car body cross-sections.
