Problems solved by technology
[0003] Among them, the transmission network is an uncertain factor. In places where there is no wireless network coverage or the wireless network signal is poor, it is often impossible to receive GPS signals, so positioning cannot be achieved.
For example, in some underground garages, the position of the car in the garage cannot be determined due to the inability to obtain GPS signals. When picking up the car, it is difficult to find the parking position.

The invention discloses a transportation-tool positioning and searching method, a positioning device and a mobile terminal. The transportation-tool positioning method is used for determining the positions of transportation tools in a preset site, and includes the steps that the surrounding environment information of the transportation tools is collected; the surrounding environment information is compared with a pre-obtained map of the preset site to determine the positions of the transportation tools in the preset site. By means of the transportation-tool positioning and searching method in the mode, the positions of the transportation tools can be determined without GPS positioning, and the functions of accurate searching, positioning, navigation and the like of the transportation tools are achieved.
Description
technical field [0001] The present invention relates to the technical field of positioning, in particular to a positioning and searching method, device and mobile terminal for vehicles. Background technique [0002] GPS (Global Positioning System) is a system that uses GPS positioning satellites to perform real-time positioning and navigation around the world. Almost all existing vehicles such as automobiles or mobile terminals (such as mobile phones, smart wearable devices, etc.) are equipped with GPS systems. GPS can provide functions such as vehicle positioning, anti-theft, anti-robbery, driving route monitoring, and call command. To realize all the above functions must have three elements of GPS terminal, transmission network and monitoring platform. [0003] Among them, the transmission network is an uncertain factor. In places where there is no wireless network coverage or the wireless network signal is poor, it is often impossible to receive GPS signals, so that posi...
