摘要
介绍了目前国内外鞋楦数字化的现状,重点对比了接触式测量、激光扫描和立体视觉3种方法。接触式测量可靠性高,但必须进行测头半径补偿,测量速度较慢,会磨损测头和划伤工件表面,并且无法测量细微的位置和死角。激光扫描法测量精度相当高,可测量柔软易脆对象,不做测头半径补偿,工作距离大,范围广,但是容易受物件表面光学性质影响,设备精密,价格昂贵。立体视觉方法也可测量柔软易脆对象,速度快,硬件简单,价格低廉,并且不会抹平模型上的尖点。立体视觉方法是目前正在发展的1种图像测量方法,与前2种方法相比,同样能完成鞋楦数字化,但是在鞋模的定制方面更为合适。
It is the key of computer-aided shoemaking to digitize shoe model, and there have been some methods such as contacting measure, laser measure, and machine vision measure, and so on. Though reliable, it is slow of contacting measure, and the equipment possibly scratches some nicks in the measure head and part, and it is difficulty to deal with fine areas and narrow angles. More precisely, laser measure can do with soft and fragile parts, and do not need to compensate the radius of the measure head. It can cover a large range. But the measure result of laser measure is often influenced by the surfaces which have different optics properties. The equipment of this way mounts precious lens, so it had to be very expensive. Machine vision measure also can do with soft and fragile parts, rapidly and cheap without precious section. Unlike the other methods, this way does not smooth the sharp point of model. Machine vision measure maybe is the most adaptable way to digitizing foot models.
