Wright Laboratory is investigating techniques that will enhance automation of 3-D scanning systems. To assist that effort, Wright Laboratory, in cooperation with Wright State University, has built a flexible 3-D scanner platform. After mounting a camera and laser on the platform, new techniques were developed for camera-laser alignment and calibration, 3-D scanning, and 3-D surface point calculation. Of particular interest is the novel algorithm for computing 3-D surface points. Given a camera and laser pointing at a 3-D object, triangulation can calculate the 3-D surface points. The calibration procedure used by others to do this is not completely reliable in that the linear models used in camera lens distortion and geometry assumptions do not always accurately reflect what is happening in the non-linear real world. Here, we introduce a technique that compensates for the real-world application by doing a system-wide nonlinear transform. Speed is added to the triangulation technique by the use of a look-up table for range and height determination. This paper provides an introduction to 3-D scanning, a summary of current camera and laser 3-D scanning approaches, a description of the Wright Laboratory 3-D scanner, and an introduction to a novel non-linear 3-D acquisition algorithm along with its alignment and calibration procedure.","PeriodicalId":171918,"journal":{"name":"Proceedings of the IEEE 1995 National Aerospace and Electronics Conference.

Object oriented analysis (OOA) was selected to make use of the perceived advantages it offers such as data modeling, encapsulation of objects and their behavior, the potential for reuse, and its ability to scale-up to huge systems. The goal of the analysis was to create a set of OOA models that describes: (1) the implementation of the current (physical) enterprise; (2) the essential (logical) enterprise requirements of a combined Air Force and Navy integrated training management system; and (3) the essential (logical) enterprise requirements of an enhanced combined Air Force and Navy integrated training management system. The enterprise models will be used as a springboard for the development of requirement specifications for a training integration management system (TMS). TMS will be an automated system that manages all undergraduate flying/aviation training. It will support the Ground Based Training System. We present the steps taken in the analysis and modeling process for the creation of these enterprise models including: (1) object-oriented methodology, CASE tool and database selection; (2) user-driven paradigm mix and migration, (3) data collection process; (4) classification and development of class/object views: 5) development of information (functional) flow views; (6) development of dynamic (time dependent views; (7) user validation of current enterprise views; (8) future system enhancements and improvements; and (9) lessons learned.","PeriodicalId":171918,"journal":{"name":"Proceedings of the IEEE 1995 National Aerospace and Electronics Conference.

Processor storage is obviously the most desirable medium from a performance perspective, however, it is also the most costly. The other extreme is off-line storage such as a tape cartridge system which is the most inexpensive method but leaves much to be desired with respect to user response time. A reasonable alternative is DASD. In fact, in many installations the \"DASD farm\" is comparable in cost to the Central Processing Unit (CPU) configuration. The Department of Defense (DOD) is in the process of reducing costs and improving productivity by migrating and consolidating existing application software onto state-of-the-art computer hardware. Integral to this effort is: the Government's attempt to optimize the hardware data storage configurations required to support its users. Through simulation modeling, the BMC manager can analyze alternative configurations without actually incurring the associated expense. The simulation effort discussed in this paper describes an approach taken to model the DASD subsystem. A model was built using the SLAM simulation language.","PeriodicalId":171918,"journal":{"name":"Proceedings of the IEEE 1995 National Aerospace and Electronics Conference.

This paper describes several interconnect technologies being developed at Honeywell. Serial, high speed (approximately 1 Gbit/sec) fiber optic data communication modules are being developed for applications including local area networks, links to peripherals and supercomputer cabinet-to-cabinet interconnects. These modules are being incorporated onto boards under the \"PRISM\" program to be inserted in the Intel Paragon supercomputer in order to enable this machine to be expanded to two rows of cabinets separated by 10-20 meters. Polymer waveguides are used to provide high density board and backplane integrated optical interconnects, and are also used to package optoelectronic devices together with conventional electronic die in multichip modules (MCM) using conventional fabrication procedures. An expanded beam parallel waveguide connector allows 32 optical channels to replace one electrical pin in a standard SEM-E connector. Polymer waveguides have interconnect densities 50/mm, and have been integrated with conventional circuit board material in industry-standard flamination processes. Systems in the next 3 to 5 year time frame will need optical interconnects at the board and backplane level if the interconnects are not to force undesirable compromises in system performance. We show that board-integrable waveguides represent the optimum choice for embedded systems. An interconnect figure-of-merit is given which shows that polyimide waveguides promise a factor of 20 speed-density-power improvement over copper interconnects.","PeriodicalId":171918,"journal":{"name":"Proceedings of the IEEE 1995 National Aerospace and Electronics Conference.

The bistatic radar system proposed in the paper contains a T/R station and an R station. Generally, the T/R station provides data such as azimuth angle and distance, and in some circumstance, elevation of a target while the R station has measurements of azimuth angle and distance sum of the target. The coordinate transform is indispensable because of the long base line of a bistatic system. Thus five measurements transformed are presented for location resolution. Theoretically, 3-D location of a target requires only three independent measurements which correspond to three independent surfaces of position, therefore, it is possible to use this data redundancy to improve location accuracy. Some papers have discussed the location methods by means of measurement subsets division, GDOP analysis of measurement subsets, simplified LMS estimation (SLMS) or selecting the best subset (SBS) for solution. The SLMS method is based on the assumption that the relevance between every two different subsets is weak correlated to be neglected. In fact, it is not so. Data redundancy has not been sufficiently used in the SBS method. A nonlinear optimized method is presented in this paper which is based on the assumption that the change of GDOP in observation space of a T/R-R system is smooth that the weighted matrix of LMS estimation in the controlled observation area can be approached by means of nonlinear LMS learning method. Monte Carlo simulation test results of different methods are also given to show the improvement in location precision.","PeriodicalId":171918,"journal":{"name":"Proceedings of the IEEE 1995 National Aerospace and Electronics Conference.

In Colorado, a large scale operational test of an ITS Mayday emergency dispatch system has been launched. This Mayday operational test in Colorado is evaluating the use of GPS location technology and cellular phone two-way communications to provide assistance to travelers in an emergency dispatch area of more than 12,000 square miles in central Colorado. The test implements 2,000 in-vehicle units using a low cost GPS location device called the TIDGET, developed by NAVSYS Corporation. The major objectives of the Colorado test are: to evaluate the impact of the system and response network on emergency response activities, time, and public safety; to evaluate a low cost system that allows user to request roadside assistance; and to identify the necessary structure, responsibilities, and service levels of a Travel Assistance Center for commercial operation of the system. The results of this emergency location project are anticipated to make a significant contribution to increased highway traveler safety and reduced emergency response time. This NAVSYS Mayday system is an example of the rapid progress by which the ITS vision is becoming a reality in today's travel technology.","PeriodicalId":171918,"journal":{"name":"Proceedings of the IEEE 1995 National Aerospace and Electronics Conference.
