摘要：
A system and method for determining an optimal position of an eye relative to an ophthalmic device are disclosed. One embodiment of the method includes receiving data comprising an image of a surface of an eye with the eye at a first position relative to an ophthalmic device. An edge feature in the image is located, and a sharpness calculation on the edge feature is performed using a predetermined algorithm to yield a sharpness value. The eye surface is then adjusted to a second position relative to the ophthalmic device, and the previous steps are repeated until the sha rpness value is maximized, which is an indication that an optimal eye position has been achieved. An embodiment of the system includes a processor and a software package executable by the processor, the software package adapted to perform the calculations as above. Means are also provided for adjusting the eye surface to a second position relative to the ophthalmic device.本發明係揭露一用以決定一眼睛相對於一眼科器材的一最適位置之系統及方法。該方法的一實施例係包括接收包含一眼睛的一表面之一影像之資料而其中該眼睛位於一相對於一眼科器材之第一位置。定位出影像中的一邊緣特性，且利用一預定演算法進行該邊緣特性上之一敏銳度計算以產生一敏銳度數值。眼睛表面隨後被調整至一相對於眼科器材之第二位置，且重覆先前步驟直到敏銳度數值達到最大為止，其係指示出已經達成一最適眼睛位置。系統的一實施例係包括一處理器及一由該處理器執行之軟體套裝件，軟體套裝件適可進行如上述的計算。亦提供用以將眼睛表面調整至相對於眼科器材的第二位置之裝置。
