摘要
双目视觉传感器在三维激光扫描测量中已得到广泛应用,其标定的简易与精确程度直接影响了三维激光扫描测量仪的使用。利用含有多个圆形标志的标定块以及两步标定方法,采用动态阈值分割,边缘提取,轮廓自动跟踪等技术,实现了对其自动标定。标定结果显示,自动化程度及标定精度较高,且具有较好的抗干扰性及稳定性。
The binocular stereovision sensor has been widely used in 3D laser scanning measuring system. The automation and precision of its calibration influence the using of 3D laser .scanning measuring system. Through a calibration target with multi-circular holes and two-stages calibration algorithm, calibration automation approach for binocular stereovision sensor was achieved by using dynamic threshold segmentation, edge extraction and contour auto-tracing technology. The calibration result showed its well automation and higher precision, better anti-noise capability and stability.
