“…Current in-process sensors are based on interferometric and moiré techniques. Vision systems can be integrated with other coordinate digitizing sensors, such as touch probe sensors to acquire at high speed high precision coordinates acquisition of complex features in mechanical components [52, 53]. …”

Abstract:With the ever increasing complex sensing and actuating tasks in manufacturing plants, intelligent sensors cluster in hybrid networks becomes a rapidly expanding area. They play a dominant role in many fields from macro and micro scale. Global object control and the ability to self organize into fault-tolerant and scalable systems are expected for high level applications. In this paper, new structural concepts of intelligent sensors and networks with new intelligent agents are presented. Embedding new functionalities to dynamically manage cooperative agents for autonomous machines are interesting key enabling technologies most required in manufacturing for zero defects production.

“…Wang and Butler [11] presented an approach that uses machine vision and image processing techniques to permit transformations of the coordinate systems for a workpiece to be measured in an arbitrary orientation on the table of the CMM. Nashman [12] described the various sensors, such as vision and touch sensors, for dimensional inspection. She considered the current use of vision and touch sensors in dimensional inspection for developing CMMs.…”

This paper presents the development of a CAD-based and vision-aided precision measurement system. A new coordinate system alignment technique for coordinate measuring machines (CMMs) is described. This alignment technique involves a machine vision system with CAD-based planning and execution of inspection. The determination method for measuring datums for the coordinate measuring technique, using the AutoCAD development system, is described in more detail. To improve image quality in the machine vision system, a contrast enhancement technique is used on the image background to reduce image noise, and an on-line calibration technique is applied. Some systematic errors may be caused by imperfect geometric features in components during coordinate system alignment. This measurement system approach, with its new measuring coordinate alignment method, can be used for high-precision measurement to overcome such errors.
