| Abstract: | A high accuracy measurement method for a 3D moving object with specified marks is presented in this paper.Several subpixel image processing algorithms are used to derive the object posion and grating intersections.A new camera calibration and correction method is introduced and used.With these techniques,the 3D movement of objects is measured accurately with multicamera system. |
