【 摘 要 】

This paper gives firstly a brief analysis of the harm of the shape deviation of pressure vessel head and disadvantages of traditional head mechanical contact measurement. On the basis of these, a non-contact laser-scanning measurement is presented. And then this paper introduces its principle, and analyzes in detail existing errors in measuring the head contour. Finally, Simulated defect measurement results are presented in the paper.
