| 摘 要： | 为了提高基于CCD测量系统的测量精度,对传统的基于CCD的测量方法和测量精度进行了研究。当CCD成像平面与被测物体成一夹角α时,导出空间距离与图像像素之间的非线性关系。提出了通过标定和校准来提高基于CCD测量精度的新方法。实际结果表明,该方法可满足对大尺寸物体的高精度测量。 |

| Abstract: | For improving measurement accuracy of the measurement system based on CCD, the traditional measurement systems are analyzed. As the CCD imaging plane inclined an angle as α with the object to be measured, the nonlinear relation between the space distance and image pixel is turned up. By demarcating and calibrating, a new higher accuracy method is brought out. The result shows that the method can gain high accuracy for large-sized object measurement. |
| Keywords: | CCD measurement accuracy space distance nonlinear relation large-sized object |
