Abstract:Aiming at the centring problem in the triangulation system with two CCD,a new scheme which uses single CCD assisted by a controllable turning machinery for 360? light-sectioning profile measuring is presented.The measuring principle and system setup are given.Moreover,the calibration theory of the mapping function method as well as its implement are also introduced in detail.Experimental results for 3-D object show that besides having all advantages of the light-sectioning system with two CCD,this approach can realize automatic centring and has a simple data blending,high measurement accuracy and lower cost.
Keywords:Three  dimension object  Light section  Proflemetry  Calibration  Accuracy
