Problems solved by technology
Because the map data and positioning technology of indoor navigation technology and outdoor navigation technology are different, the accuracy of the current indoor and outdoor integrated navigation system is low, making the application of indoor and outdoor integrated positioning and navigation system unable to be widely promoted.
[0005] Aiming at the problem in the prior art that there is no good indoor and outdoor integrated navigation system due to the difference in map data and positioning technology between indoor navigation technology and outdoor navigation technology, it is necessary to provide an outdoor navigation system that can provide high precision The method of fusing the indoor navigation system on the basis of and the method of using this fusion technology for navigation

Embodiment Construction
[0042] Below, the structure and working principle of the present invention will be further described in conjunction with the accompanying drawings.
[0043] Such as figure 1 As shown, a fusion method of indoor and outdoor navigation of the present invention comprises the following steps:
[0044] S1. Acquire first original map data for outdoor navigation and second original map data for indoor navigation. Among them, the first map raw data may include but not limited to outdoor electronic map element information data such as building position data, outline data, street position data, and street size data, and the second map raw data may include but not limited to building outlines Data, floor data, indoor point of interest data, elevator data, staircase data, indoor road data and other indoor electronic map element information data.
[0045] S2. Establishing a high-precision Gaussian plane rectangular coordinate system for determining Gaussian coordinate data of one or more ...

The invention discloses indoor and outdoor navigation integration and a navigating method. An integration method includes: acquiring original data of a first map and a second map; establishing a high-precision gaussian rectangular plane coordinate system; selecting border triggering areas; determining first longitude and latitude coordinate data and first gaussian coordinate data of the border triggering areas; acquiring second map data. The navigating method includes: acquiring the original data of the first map and the second map according to the integration method, and navigating accordingto the obtained original data of the first map and the second map. The indoor and outdoor navigation integration and the navigating method have the advantages that seamless integration of the indoor and outdoor navigation can be realized, and positioning precision and navigating precision of integrated indoor and outdoor navigation are increased.
Description
technical field [0001] The invention relates to the technical field of wireless communication, in particular to a fusion of indoor and outdoor navigation and a navigation method. Background technique [0002] With the continuous development of wireless communication network technology, navigation technology is becoming more and more popular, so that people can rely on mobile phones, computers or vehicle-mounted navigation systems to meet the needs of positioning and route planning during daily travel. [0003] At present, outdoor navigation technology has become more and more mature, and has relatively accurate and high-precision positioning and route planning functions, making people's outdoor activities more convenient. And when people are active indoors, such as shopping malls, exhibition halls, office buildings, etc., they need to use indoor navigation technology to complete the navigation. [0004] However, most situations in life require combined application of outdoo...
