Abstract
In recent years, smart city has attracted more and more attention because of its high intelligence and informatization. In the future, smart community, smart parking lot and smart exhibition hall will enter people's life. In these smart services, indoor navigation and positioning technology is the basic technology. High precision indoor and outdoor seamless positioning technology plays a vital role in people's future life, is the science and technology source power to promote public innovation and entrepreneurship, and is an important part of supporting the national strategic needs. At present, indoor navigation is still facing challenges such as high cost, poor adaptability and poor endurance. In this paper, combined with threedimensional( 3D) visualization technology, indoor navigation is designed and applied. The results show that the indoor navigation system combines indoor positioning and artificial intelligence to achieve multichannel positioning and reduce power consumption, which can be widely used in the construction of smart city and bring convenience to people's life.
Highlights
In the 21st century, with the rapid development of wireless communication technology and Internet technology, people's demand for location-based services is growing, so wireless navigation and positioning technology has made great progress.[1]
With the increasing demand for indoor positioning, it is urgent to develop various technologies suitable for indoor positioning and navigation according to the data obtained from indoor digitization.[3]
Indoor navigation still faces many challenges, mainly including: 1) high cost and complexity, such as infrared, ultrasonic and other hardware facilities are required to achieve positioning and navigation, which limits the popularity of indoor positioning; 2) It has poor adaptability to dynamic environment, and the movement of some people or objects will affect the positioning accuracy; 3) The endurance is poor
Summary
In the 21st century, with the rapid development of wireless communication technology and Internet technology, people's demand for location-based services is growing, so wireless navigation and positioning technology has made great progress.[1] So far, GPS, Beidou and other satellite positioning systems have been able to provide all-weather, real-time navigation services. It is more and more urgent to digitize indoor environment and provide location-based services with indoor data. Due to the occlusion of buildings, the satellite signal decays rapidly, and the effective position information can not be obtained from it, resulting in poor positioning effect. With the increasing demand for indoor positioning, it is urgent to develop various technologies suitable for indoor positioning and navigation according to the data obtained from indoor digitization.[3]. The purpose of this study is to use the mobile 3D scanning system to digitize the indoor space, import the results of digitization (mainly point cloud data and panoramic image) into the platform of indoorviewer, and use the platform to publish the 3D real scene information of indoor space online for the use of terminal equipment
