| 中文摘要: |
| 图像分辨力大大低于胶片是数字图像处理的一大弱点,此弱点极大地限制了数字图像处理技术在精密测量等领域的应用.亚像素软件处理技术能弥补这一缺点.介绍了常用的亚像素处理技术,以及提高角度精确度和边缘检测的方法. |
| 英文摘要: |
| The fault that the picture resolution of digital image processing is much worse than film greatly limits the application of digital image processing techniques in measurements.Sub-pixel techniques can mend this fault.In this paper,we introduce the common sub-pixel processing techniques and methods in improving accuracy of angular measurement and edge detection. |
