DISTRIBUTION CODE ABSTRACT (Maximum 200 Words)Polymorphous Computing Architectures (PCA) rapidly "morph" (reorganize) software and hardware configurations in order to achieve high performance on computation styles ranging from specialized streaming to general threaded applications; the former is most like a pipeline processor, while the latter is most like a collection of common desktop processors. This project explored a multi-time scale morphable software environment (denoted 'milieu') whose purpose was to suggest ways to build applications from components of varying scales; these components were to include small and large amounts of code, different algorithms, and different parallelism. The purpose of PCA is to reduce the cost, size, power, and other "footprint" aspects of computing that can be most efficiently done with radically different kinds of computing elements; pre-PCA systems connect disparate parts with low utilization outcomes. This project sought to create a model-based software framework for reactive monitoring, optimization, modeling, resource negotiation and allocation, regeneration, and verification. Model-based software uses principles like "legos" or "tinker toys" to model interactions and roles, and allow a framework in which software is created. This project report addresses the research objectives and key accomplishments, while introducing the technical concepts and approaches developed in this project for the PCA software development. Future work is also recommended in this report.
The objective of this work is to develop a 3D measuring system for on-line 3D measurement in industry locale. Our system is based on the depth image using a structured-light method. A generator emitting a single stripe light and a camera are used to establish a 3D vision measurement system which is also called as a subsystem. But it only can obtain the depth image of a part at the measured object section. Our system is made up of four subsystems placed symmetrically in space. The depth images obtained by the subsystems are joined to form the depth image of a full section. If the object is uniformly shafted along a fixed beeline direction, the depth image of the full object surface is achieved. The indefiniteness in the image combination criterion can be removed when using the depth image. This paper introduces the system principle and the mathematical model. The algorithm is proposed with system parameters. A prototype is developed. The system has the range of 100mm in height x 100mm in width. The length is not limited. The measuring error is less than 0.5mm in height and width and less than 0.01mm in length. The characteristics make the system suitable for on-line 3D shape measurement and non-contact measurement with high speed.
