Abstract:

To help the worker locate himself and reach the work field in time to carry out equipment maintenance in dark indoor environment, an indoor positioning and route guidance system was designed with the principle of inertial navigation in this paper. Then, based on iOS, the corresponding application APP was developed. Through the experimental test, this APP completed autonomous indoor guidance. In addition, a threshold made when using acceleration reduced the time cumulative error of inertial navigation.
