摘要	Aimed at the problems in measuring the three dimensional weld pool surface in tungsten inert gas arc welding in existing methods, which are hardly applied in the strong arc light, high temperature radiations and specular refection. A novel method named laser-vision was developed, and the measurement system was established. The experiments with laser dot matrix and parallel lines pattern were performed and the reflected laser distorted images were captured by a high speed camera. The reflected laser dot coordinate and its transfer model between projected laser dot coordinate were extracted and established, respectively. The geometric parameters of the weld pool surface were obtained offline. The comparison of the extracted and measured result shows that the proposed method can successfully measure the three dimensional information of the weld pool surface and the extracted results coincide with the actual measurement well. The error of width, length and convexity is 0.8%, 0.6% and 4.7%, respectively. This paper provides a new method for control of 3D weld pool surface in real-time. ©, 2015, Shanghai Jiao Tong University. All right reserved.
