Embodiment 1

[0082] Embodiment one, as figure 1 As shown, a seam switching indoor and outdoor joint positioning method includes the following steps:

[0083] S1: Obtain the location area where the target to be located is located, and perform area identification on the location area to obtain an area identification result;

[0084] S2: Judging the positioning mode of the target to be positioned according to the area recognition result, and locating the target to be positioned according to the determined positioning mode, to obtain target position information of the target to be positioned;

[0085] Wherein, judging the positioning mode of the target to be positioned according to the area identification result is specifically implemented as follows: when the area identification result is an indoor area, the positioning mode corresponding to the target to be positioned is an indoor positioning mode; When the recognition result is an outdoor area, the positioning mode corresponding to the obj...

Embodiment 2

[0134] Embodiment two, such as Image 6 As shown, a seamless switching indoor and outdoor joint positioning system is applied to the seamless switching indoor and outdoor joint positioning method in Embodiment 1, including a central processing unit and a positioning module, and the central processing unit communicates with the The positioning module is connected in communication;

[0135] The central processing unit is used to obtain the location area where the target to be located is located, and perform area identification on the location area to obtain an area identification result;

[0136] The central processing unit is further configured to judge the positioning mode of the target to be positioned according to the area identification result;

[0137] Wherein, when the area identification result is an indoor area, the positioning mode corresponding to the target to be positioned is an indoor positioning mode; when the area identification result is an outdoor area, the po...

Abstract

The invention relates to a seamless switching indoor and outdoor joint positioning method and system. The method includes acquiring the location area where a target to be positioned is located, and performing area identification on the location area to obtain an area identification result; judging the location of the target to be located according to the area identification result positioning mode, and locate the target to be positioned according to the determined positioning mode, and obtain the target position information; when the area identification result is an indoor area, the positioning mode corresponding to the target to be located is an indoor positioning mode; when the area identification result is an outdoor area, The positioning mode corresponding to the target to be positioned is the outdoor positioning mode; when the area recognition result is an indoor-outdoor switching area, the positioning mode corresponding to the target to be positioned is the indoor-outdoor switching positioning mode. The present invention can quickly and accurately identify the indoor and outdoor states of the target, select a suitable positioning mode to accurately locate the target, realize seamless switching between indoor positioning and outdoor positioning, and effectively improve positioning accuracy.

Description

technical field [0001] The present invention relates to the technical field of indoor and outdoor positioning, in particular to a seamless switching indoor and outdoor joint positioning method and system. Background technique [0002] With the development of human society and the rise of smart cities, people's demand for positioning technology is increasing. Positioning technology has important applications in various fields such as commercial activities, scientific research, emergency search and rescue, and crimes. [0003] According to the scope of the positioning system, there are mainly two types of positioning technology: indoor positioning and outdoor positioning. At present, outdoor positioning includes GPS / Beidou positioning and GNSS positioning, and indoor positioning mainly includes positioning methods based on WIFI, infrared, ultrasonic, Bluetooth and RFID. However, both outdoor positioning and indoor positioning have their own limitations, and can only be used ...
