Embodiment 1

[0048] This embodiment provides a method for quickly constructing a map to assist indoor positioning in an emergency rescue scene. The emergency rescue scene occurs in a target building, and the method for quickly constructing a map to assist indoor positioning in the emergency rescue scene is performed by rescuers. Rescuers wear sensing modules. see figure 1 , which is shown as a schematic flow diagram of the rapid construction of map-assisted indoor positioning method in the emergency rescue scene, as shown in figure 1 As shown, the rapid construction map-assisted indoor positioning method in the emergency rescue scene includes:

[0049] S1. Construct a three-dimensional map of the target building. In this embodiment, the target building is searched through Google Maps, and the outline of the target building is obtained. Measure the length of each side of the target building through the distance measurement function of Google Maps. Draw a plan map of the target building ...

Embodiment 2

[0093] This embodiment provides an indoor positioning system for quickly building a map in an emergency rescue scene. The emergency rescue scene occurs in a target building. The positioning system is implemented by a rescuer who wears a sensor module. In the emergency rescue scene, a map-assisted indoor positioning system is quickly built, and the handheld terminal and the remote control center cooperate to complete the emergency rescue. see Figure 5 , which is a schematic diagram of the principle structure of the rapid construction of map-assisted indoor positioning system in the emergency rescue scene. Such as Figure 4 As shown, the rapid construction map-assisted indoor positioning system 1 in the emergency rescue scene includes: a three-dimensional map construction module 11, an instruction output module 12, an initial position acquisition module 13, a data reading module 14, a data processing module 15, and a calculation module 16 , a first judgment module 17 , a firs...

Abstract

The invention provides a method for quickly setting up a map to assist indoor positioning under an emergency rescue scene. The method comprises the following steps: setting up a three-dimensional map of a target building; obtaining initial position coordinate information of a rescuer entering the target building; reading sensing data and processing the sensing data; deducing the walking position coordinate information of the rescuer at the current moment through a pre-stored calculation algorithm; with one of double feet of the rescuer as a reference foot, judging whether the reference foot is in a static state at the current moment, if so, correcting a calculation error and an accumulative position calculation error, and outputting corrected walking position coordinate information of the rescuer at the current moment, otherwise, outputting deduced walking position coordinate information of the rescuer at the current moment; marking the walking position coordinate information of the rescuer at the current moment in the three-dimensional map of the target building. The method provided by the invention is used for dynamically tracking the rescuer in real time and providing assistance for integral command and dispatch of emergency rescue and the life guarantee of the rescuer.

Description

technical field [0001] The invention belongs to the field of indoor positioning, and relates to a positioning method and system, in particular to a method and system for quickly constructing a map to assist indoor positioning in an emergency rescue scene. Background technique [0002] The current mature indoor positioning methods are mainly based on WIFI, Bluetooth, WLAN, RFID, UWB and other wireless technologies, as well as dead reckoning and inertial navigation methods based on inertial sensors. Among them, different indoor positioning technologies are suitable for different applications. All positioning methods based on wireless technology rely on the deployment of related base station equipment in advance and require the establishment of a signal characteristic database. However, in emergency rescue scenarios, it is usually impossible Ensure that the above-mentioned required facilities are installed in the rescue site, and its specific location cannot be known in time, a...
