Utilizing the layered sensing paradigm, an area is surveyed by a multitude of sensors at many different altitudes and operating across many modalities. Utilizing a combination of sensors provides better insight into a situation than could ever be achieved with a single sensor. A fundamental requirement in layered sensing is to first register, stabilize, and normalize the data from each of the individual sensors. This paper extends our previous work [1] to include experimental analysis. The paper contribution provides an evaluation of four registration algorithms now including the (1) Lucas-Kanade (LK) algorithm, (2) the Ohio State University (OSU)1 correlation-based method, (3) robust data alignment (RDA), and (4) Scale Invariant Feature Transform (SIFT). Results demonstrate that registration accuracy and robustness were achieved with the LK and correlation-based methods over the others for image-to-image registration, restricted adaptive tuning, and stabilization over warped images; while the SIFT outperformed the others for partial image overlap.","PeriodicalId":305765,"journal":{"name":"Proceedings of the IEEE 2009 National Aerospace & Electronics Conference (NAECON)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121777321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A vehicle's engine control unit (ECU) manages and controls various sensor signals and determines the output in terms of torque, fuel quantity and actuator positions. The data available in the ECU is however restricted only to that particular vehicle where it was generated. This work presents a scenario where critical data from each vehicle is broadcasted and a dynamic adhoc network of vehicles is formed. The algorithms in the ECU then detect possible collisions, decide which vehicle should take action and alert the driver with the most optimum response. The analysis presented here is based on simulation data. Traffic management is achieved with modules placed along the road, which collect the broadcasted data. Modules, after analyzing traffic density and average speeds, interact with neighboring modules. This traffic information is broadcasted to all vehicles in close proximity to the traffic modules. The vehicle uses this information along with details from the navigation system to reroute the automobile to avoid high traffic areas.","PeriodicalId":305765,"journal":{"name":"Proceedings of the IEEE 2009 National Aerospace & Electronics Conference (NAECON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130653949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Broadcast digital radio transmissions (e.g., digital TV signals) contain field and segment sync codes, which can be used for ranging even though it was not originally designed for so. Another example is the wireless local area network (WLAN) signals. However, there are two major difficulties. Although the location of SOOP sources is known, the number of independent SOOP sources and their geometric distribution may not be favorable for precise positioning. Besides, the clocks of SOOP transmitters are not synchronized, each subject to a different bias and drift. To respond to the 2009 NAECON Grand Challenge, we set forth a cooperative position location approach. The proposed concept makes use of differential ranges between cooperative devices to a common SOOP source, the relative ranges between the cooperative devices, and displacement measurements by the cooperative devices. The cooperation among networked location devices not only allows them to choose the most appropriate positioning mechanism but also provides them with additional measurements to reduce the number of SOOP otherwise required. In addition to data exchange, the radio link between two cooperative devices also allows for estimation of their clock offset. This leads to a joint position location solution via fixed-point smoothing. In this paper, we present the proposed system concept, its subsystems, and their operations and also analyze preliminary simulation results.","PeriodicalId":305765,"journal":{"name":"Proceedings of the IEEE 2009 National Aerospace & Electronics Conference (NAECON)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127999469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
