Abstract

The invention provides a head-mounted smart wearable device, a positioning system, and a positioning method. The method includes: acquiring positioning reference data, which includes any one or more types of positioning information as follows: GPS information, inertial navigation information and Wi-Fi information; according to the positioning information in the positioning reference data, determining a piece of first position information; acquiring a navigation map, and shooting and collecting environmental image data; according to the first position information, the environmental image data and the navigation map, acquiring and then displaying corresponding navigation positioning information. The method and system can increase positioning precision and improve travel safety of users.

Description

technical field [0001] The invention relates to the field of mobile smart devices, in particular to a head-mounted smart wearable device, a positioning system and a positioning method. Background technique [0002] With the continuous expansion of city scale and the continuous increase of people's activity range, people's location or environment is not the area they are familiar with in many cases. Therefore, it is more and more important to identify the direction in time and quickly determine the route to the destination. [0003] In the existing technology, smart phones, smart watches and other smart wearable devices with GPS positioning function can usually be used as navigation tools. However, when navigating through smart phones, smart watches and other smart wearable devices, the user will In many cases, for example, when the user is walking or running, if the user frequently checks the navigation guidance, the user's attention will be distracted, which will cause pot...
