In this paper, we have proposed a CROWD-PAN-360 (CP360), novel smartphone-based system to generate 360-degree panoramic map of a querying user for his unfamiliar surrounding using crowd-sourced images. The objects (logical locations) appearing in the images are identified using manually or automatically generated tags. The system is context-aware and it intelligently associates user location coordinates with several smartphone contexts, like acceleration and orientation. CP360 can significantly reduce GPS positional errors for even cheap low-end smartphones and can identify the user surroundings very efficiently. We extensively tested the system in both indoor and outdoor environments of IIT Roorkee campus using Android smartphones over a dataset of more than 6000 crowd-sourced images of nearly 70 objects (departments, hostels, cafeteria, etc.) and CP360 generates the panoramic map with an average accuracy of 92.2%.<\/span><\/span><\/span>\n<\/p>\n<p style=\"text-align: justify;\">\n\t&nbsp;\n<\/p>\n<p style=\"text-align: center;\">\n\t<img decoding=\"async\" alt=\"\" src=\"https:\/\/www.braininspirednavigation.com\/wp-content\/uploads\/2015\/07\/073015_0804_CROWDPAN3601.png\" \/><br \/>\n\t&nbsp;\n<\/p>\n<p style=\"text-align: justify;\">\n\t<span style=\"font-family:times new roman,times,serif;\"><span style=\"font-size:18px;\"><span style=\"color: black;\">Raychoudhury, V.; Shrivastav, S.; Sandha, S.S.; Cao, J., <strong>&quot;CROWD-PAN-360: Crowdsourcing Based Context-Aware Panoramic Map Generation for Smartphone Users,&quot;<\/strong>&nbsp;<em>Parallel and Distributed Systems, IEEE Transactions on<\/em>, vol.26, no.8, pp.2208,2219, Aug. 1 2015<\/span><\/span><\/span>\n<\/p>\n<p style=\"text-align: justify;\">\n\t<span style=\"font-family:times new roman,times,serif;\"><span style=\"font-size:18px;\"><span style=\"color: black;\">doi:10.1109\/TPDS.2014.2345067<\/span><\/span><\/span>\n<\/p>\n<p style=\"text-align: justify;\">\n\t<span style=\"font-family:times new roman,times,serif;\"><span style=\"font-size:18px;\"><span style=\"color: black;\">keywords:Context-aware;&nbsp;crowd-sourcing;&nbsp;location-based services;&nbsp;smartphone sensing<\/span><\/span><\/span>\n<\/p>\n<p style=\"text-align: justify;\">\n\t<span style=\"font-family:times new roman,times,serif;\"><span style=\"font-size:18px;\"><span style=\"color: black;\">URL:<a href=\"http:\/\/ieeexplore.ieee.org\/stamp\/stamp.jsp?tp=&amp;arnumber=6871426&amp;isnumber=7155620\"><span style=\"color:blue; text-decoration:underline\">http:\/\/ieeexplore.ieee.org\/stamp\/stamp.jsp?tp=&amp;arnumber=6871426&amp;isnumber=7155620<\/span><\/a><\/span><\/span><\/span>\n<\/p>\n<p>\n\t&nbsp;\n<\/p>\n<p>\n\t<span style=\"color:black; font-family:Segoe UI; font-size:7pt\">&nbsp;<\/span>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CROWD-PAN-360: \u4e00\u79cd\u9762\u5411\u667a\u80fd\u624b\u673a\u7528\u6237\u7684\u4f17\u5305\u4e0a\u4e0b\u6587\u611f\u77e5\u5168\u666f\u5730\u56fe\u751f\u6210\u65b9\u6cd5 &nbsp; &nbsp; &nbsp; &nbsp; \u968f\u7740\u667a\u80fd\u624b\u673a\u548c\u4f4d\u7f6e\u611f\u77e5\u670d\u52a1\u6280\u672f\u53ca\u5e94\u7528\u7684\u5feb\u901f\u53d1\u5c55\uff0c\u5f80\u5f80\u9700\u8981\u8bc6\u522b\u7528\u6237\u76f8\u5bf9\u4e8e\u5468\u56f4\u73af\u5883\u7684\u4f4d\u7f6e\uff0c\u800c\u4e0d\u662f\u539f\u59cb\u7684\u4f4d\u7f6e\u5750\u6807\u4fe1\u606f\u3002\u5728\u672c\u6587\u4e2d\uff0c\u4f5c\u8005\u63d0\u51fa\u4e86\u4e00\u79cdCROWD-PAN-360&nbsp;(CP360)\uff0c\u901a\u8fc7\u4e00\u79cd\u57fa\u4e8e\u667a\u80fd\u624b\u673a\u7684\u8f6f\u4ef6\u7cfb\u7edf\u5229\u7528\u4f17\u5305\u56fe\u7247\u751f\u6210\u7528\u6237\u6240\u4e0d\u719f\u6089\u5f97\u73af\u5883\u7684360\u5ea6\u5168\u666f\u5730\u56fe\u3002\u901a\u8fc7\u624b\u52a8\u6216\u8005\u81ea\u52a8\u4ea7\u751f\u7684\u6807\u7b7e\u8fdb\u884c\u6807\u8bc6\u51fa\u73b0\u5728\u56fe\u7247\u4e2d\u7684\u5bf9\u8c61\u7684\u903b\u8f91\u4f4d\u7f6e\u3002\u8fd9\u79cd\u4e0a\u4e0b\u6587\u611f\u77e5\u7684\u7cfb\u7edf\u80fd\u591f\u5c06\u7528\u6237\u7684\u4f4d\u7f6e\u5750\u6807\u4e0e\u82e5\u5e72\u4e2a\u667a\u80fd\u624b\u673a\u7684\u4e0a\u4e0b\u6587\uff08\u5982\u52a0\u901f\u5ea6\u3001\u65b9\u5411\uff09\u8fdb\u884c\u667a\u80fd\u5173\u8054\u3002CP360\u80fd\u591f\u6709\u6548\u964d\u4f4eGPS\u5b9a\u4f4d\u7684\u8bef\u5dee\u5e76\u4e14\u80fd\u591f\u6709\u6548\u8bc6\u522b\u7528\u6237\u7684\u73af\u5883\u3002 &nbsp; Abstract&mdash;Recent advances in smartphones and location- ware services&nbsp;necessitate identifying logical locations of users, in terms of their surroundings, instead of raw location coordinates.
