Embodiment 1
[0054] This embodiment provides a method for dynamic data collection of ubiquitous positioning signals and fingerprint library construction, please refer to figure 1 , the method includes:
[0055] Step S101: Dynamically collect current location coordinate information and AP signal information, and store the collected coordinate information and AP signal information as a dynamic fingerprint library data file.
[0056] Specifically, the inventors of the present application have discovered through a large amount of research and practice that indoor and outdoor positioning systems have a rich development history and a wide variety of technologies. However, there is currently no system that can directly provide ubiquitous indoor and outdoor positioning services. The main reason is the need to deploy additional local signal transmission infrastructure. Indoor and outdoor positioning systems that can leverage existing infrastructure are commonly used today, and most of these techno...
Embodiment 2
[0071] This embodiment provides a matching positioning method, please refer to Image 6 , the matching targeting methods include:
[0072] Step S201: outputting AP signal information scanned by the device to be positioned to obtain a data sequence to be positioned, wherein the data sequence to be positioned includes a plurality of AP signals;
[0073] Step S202: Matching the AP signal information contained in the data sequence to be positioned with the information in the signal dynamic fingerprint database to obtain the current positioning coordinates.
[0074] Specifically, the embodiment of the present invention provides a matching and positioning method, which mainly adopts dynamic fingerprint library construction and matching to obtain the position of the positioning object. The fingerprint positioning method means that the equipment to be positioned is pre-equipped with the signal fingerprint database of the building, and the current positioning result is obtained by mat...
Embodiment 3
[0090] This embodiment provides a ubiquitous positioning signal dynamic data collection and fingerprint database construction system, please refer to Figure 8 , the system consists of:
[0091]The signal dynamic collection module 301 is used to dynamically collect current location coordinate information and AP signal information, and store the collected coordinate information and AP signal information as dynamic fingerprint database data files.
[0092] Specifically, the acquisition personnel can dynamically collect time stamps, current location coordinate information, receivable AP mac and signal strength information through the signal receiving end measurement equipment during the moving process according to the collection line; use the storage output program to store the time Stamp, real-time location coordinate information, received AP mac and signal strength information are stored as dynamic fingerprint library data files. It should be noted that, in other embodiments, ...
