Route planning in handheld blind navigation system based on RFID
Lin Xin-nong · Jisuanji gongcheng yu sheji · 2012
A route planning algorithm for blind navigation system with internet of things technolog is proposed.By using shortest-path algorithm as a basic algorithm,relational database as the storage mode,combining with the multi-factor fuzzy algorithm to determine the road network weights,and using the spatial distribution feature of the real road network,the searching area is restricted reasonably with restricted rectangle searching area algorithm.Combining with its practical applications in blind navigation system.An actual example is given,and this method is validated by an example and emulator.
