【摘要】：面扫描三维测量技术具有非接触、测量速度快、精度高等优势,在锻压领域具有巨大的应用潜力。但是通用的面扫描三维测量设备在测量过程中易受测量规划、数据处理等人为因素影响,测量精度难以保证。为解决此问题,提出一种基于面扫描和六自由度机器手的自动化三维测量技术,该技术由六自由度机器手、三维测量头、控制系统等组成,能够充分利用机器手运动灵活、工作范围大的特点和面扫描测量速度快、精度高的优势。此外,该技术采用了一种基于矩阵直积的手眼标定算法,实现了多次测量数据的高精度自动拼合。实际应用表明,该技术能够实现复杂锻件等工业产品的快速、精确、自动三维测量和精度检测。
[Abstract]:Surface scanning 3D measurement technology has the advantages of non-contact, fast measurement speed and high precision, and has great application potential in the field of forging. However, the general surface scanning 3D measuring equipment is easy to be affected by human factors such as measurement planning, data processing and so on, so it is difficult to guarantee the measurement accuracy. In order to solve this problem, an automatic three-dimensional measurement technology based on surface scanning and six-degree-of-freedom manipulator is proposed, which is composed of six-degree-of-freedom robotic hand, three-dimensional measuring head and control system, which can make full use of the characteristics of flexible movement and large working range of the manipulator, as well as the advantages of fast and high precision of surface scanning measurement. In addition, this technique adopts a hand eye calibration algorithm based on matrix direct product, and realizes the high precision automatic assembly of multiple measurement data. The practical application shows that this technology can realize the rapid, accurate, automatic three-dimensional measurement and accuracy detection of complex forgings and other industrial products.
