摘要: 随着现代数字制造技术的快速发展，在工业产品测量领域，对微型物体几何尺寸的测量需要满足非接触、高精度、多尺寸等需求，而现有测量技术还不能达到这些要求。为了实现多尺寸、高效、快速、非接触式的精确测量，文中利用光纤耦合激光器光束质量好、线宽超细、精度高、单色性好、体积小以及免调节等优势，研制了基于光纤激光的精密非接触测量系统，提出了一种基于光纤耦合激光的超精密视觉测量方法，主要包含基于光纤线激光的目标成像、激光线滤波与提取、测量模型建立及几何参数标定、数据转换和三维重建测量等关键技术。利用光纤激光器向测量物体表面连续发射激光线，采用高分辨率相机，通过照明/不照明两次成像技术获取物体的平面尺寸和高度信息。对激光线图像进行滤波校正，快速提取激光线，对几何参数进行标定和坐标转换，然后进行处理数据，获取物体测量部位的三维测量值。实物测量和对比实验验证了文中测量方法的准确性、快速性和有效性，测量精度可达微米级。为微型物体几何尺寸的三维非接触、高精度、多尺寸测量提供了有效方法和测量仪器。

Abstract: With the rapid development of modern digital manufacturing technology, in the field of industrial product measurement, the measurement of the geometric dimensions of objects need some requirements, such as non-contact, high-precision, multiple sizes, high-volume, etc. The existing measurement technologies cannot meet these requirements. In order to achieve multiple sizes, high-efficiency, rapid, and non-contact precise measurement, fiber-coupled lasers with the advantages of good beam quality, ultra-fine line width, high precision, good monochromaticity, small size, convenient using, no adjustment, maintenance-free and high stability were used to develop a precision non-contact measurment system based on fiber lasers. A high-precision measurement method based on fiber-coupled lasers was proposed, which mainly included object imaging based on fiber-optic line laser, bilateral filtering and extraction of laser line, mathematical relationship establishment of measurement model, geometric parameter calibration, data conversion and 3D reconstruction and other key technologies. The fiber laser continuously emitted laser line to the object, adopted a high-resolution camera, and photographed the laser line image of the object through two imaging techniques of illumination/non-illumination to acquire 2D plane size and height information of the object. The laser line image was filtered and corrected, the laser line was quickly extracted, the geometric parameters were calibrated and the coordinate transformation was performed, and then the processing data was processed to obtain the measurement value of the measurement parts of the object. A large number of object measurements and comparative experiments were carried out to verify the validity and accuracy of the measurement system and measurement method. The measurement accuracy can reach micron level. It provides an efficient method and measurement equipment for the three-dimensional high-precision non-contact measurement of industrial products.
