Compared with the conventional 2-D coordinate measuring systems, the new system has great improvement at measuring speed, aiming accuracy, measuring function and degree of automation The new system consists of two parts image measuring system of displacement and image autofocusing and aiming system The displacement measuring system in which CCD camera is used for locating the optical scale not only processes the advantages of absolute code measuring system powerful noiseproof feature, good long-time stability, easily compensated ruling error of optical scale, but also has the advantages of morden numerical systems easy numeralization and intelligence The autofocusing and aiming system in which CCD camera is applied for gaining the defocusing information and edge location information of workpiece enjoys the advantages of fast autofocusing, accurate result, high accuracy of edge detection and wide range of measured parameters, etc The feasibility of the new 2-D measuring system is analyzed in this thesis and related parameters are calculated.

详细本文在分析了现有二维中小尺寸测量系统中,光学仪器的光学读数系统和调焦、瞄准系统的优缺点之后,结合现代数字化仪器的优缺点,提出研制一种新的二维图像测量机系统。与传统二维坐标测量系统相比,新型系统在测量速度、瞄准精度、测量功能及自动化程度等方面都有较大的提高。该系统由图像式位移测量系统和图像式自动调焦、瞄准系统组成。图像式位移测量系统采用CCD摄象机拾取光学线纹尺的位置信息,既具有传统光学式绝对码位移测量系统的优点—抗干扰能力强、长期稳定性好、光学标尺误差易于补偿等优点,又具有现代化数字仪器易于微机化、智能化的优点。

Because they are all derived from the behavior of single slit island under changing yardstick, which was inconsistent with the principle of slit island method that fractal dimension is calculated from the perimeter-area relation of many slit islands.

首次研究指出:文献中对码尺依赖性问题的已有解释以码尺改变时单个分形岛的行为变化为出发点,这与小岛法从大量断面小岛的周长-面积关系得到其周线分维数的测量思想不符合。

I want to buy a yardstick.

我想买把码尺

To measure a length accurately to within a millionth of an inch, we must have a measure graduated in millionths of an inch; a yardstick graduated in inches is useless.

测量百万分之一英寸的长度,需要刻度为百万分之一英寸的量尺;对此,以英寸为刻度的码尺是毫无用处的。

As they went, Robin's men hewed down great poles from the forest trees, which they took with them, and, fifty yards from the gate of St. Mary's Abbey, they set up a gallows of these poles, and on it hanged Roger the Cruel, with the Abbot's parchment of promise sewn on his breast, that all men might see. Across the foot of it Friar Tuck had written at Robin's bidding:"This doom to Abbot Hugo's hireling murderer. When next Abbot Hugo goes abroad, the doom will find him too."

当他们走时,罗宾的人从森林的树砍下树干,他们带着树干,距离圣玛利亚寺门口五十码时,他们用这些树干架起绞台,上面吊着残酷的罗格,修道院院长答应的羊皮纸挂在他的胸部,所有的人都可看见,距离一尺之处,塔克修道士写下罗宾的命令:「这是雨果修道院院长雇用谋杀者的命运,下次雨果修道院院长外出,这样的命运也将会捕捉到他。
