[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.
