本文研究了大型物体空间直线度的在线实时激光视觉准直测量技术。详细介绍了视觉对准测量的基本原理。介绍了视觉传感器、测量系统及其标定的数学模型。在此基础上，研制了一套实验系统，并对1500 mm长的无缝钢管进行了直线度检测。实验结果表明，该测量技术能够实现全在线测量，具有较高的精度和稳定性，具有实际应用价值。(C)2001 Elsevier Science B.V.保留所有权利。
In this paper, on-line and real-time laser visual alignment measurement technique is studied to measure the spatial straightness of large objects. The basic principle of the visual alignment measurement is detailed. The mathematics models of visual sensor, measurement system and their calibrations are presented. Based on the technique, an experiment system is developed and the straightness of a 1500 mm long seamless steel pipe is inspected. The experiment results show that the measurement technique can achieve total on-line measurement and it offers high precision and stability, which is of practical importance for the application.
