Abstract

The paper deals with two problems occurring when larger parts are manufactured by state of the art laser beam or water jet NC-cutting machines: first, the machine has to know the contour to cut; second, the contours of cut parts must be measured to ensure the required dimensions. The developed solution is applicable for both tasks. A large scale backlighted measuring table allows to handle parts up to 2000/spl times/1500 mm/sup 2/. The calibration problem is solved using an especially structured frosted glass plate, the desired accuracy will be reached using subpixel methods. For problems arising in real applications, e.g. how to handle the thickness of parts or how to fit images of different cameras together, solutions are proposed and implemented. A stressing point is the applicability of the developed system in an engineering environment.
大型汽车部件光学测量的亚像素精度
本文研究了目前激光或水射流数控切割机加工较大零件时存在的两个问题:首先,数控切割机必须知道要切割的轮廓;其次,必须测量被切割零件的轮廓,以确保所需的尺寸。开发的解决方案适用于这两个任务。大型背光测量台允许处理高达2000/spl次/ 1500mm /sup /的零件。采用特殊结构的磨砂玻璃板解决了标定问题,采用亚像素法可达到所需的精度。对于实际应用中出现的问题,如如何处理零件的厚度或如何将不同相机的图像贴合在一起,提出并实施了解决方案。一个重点是所开发的系统在工程环境中的适用性。
