Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
In the field of indoor positioning, two types of WIFI positioning are generally applied, one is a neighbor method, and the other is a fingerprint method. Wherein the fingerprint method is specifically explained as follows: the method comprises the steps of carrying out grid division on a positioning area, collecting WIFI fingerprints aiming at each grid, generating a corresponding model through a feature extraction algorithm, and determining the current position by comparing the WIFI fingerprints collected by equipment needing positioning. When the positioning is carried out by the fingerprint method, the positions are positioned by means of the fingerprint concept, and one WIFI fingerprint corresponds to one position.
Fig. 1 is a flowchart of a method for constructing a location fingerprint library according to an embodiment of the present invention. Referring to fig. 1, a method for constructing a location fingerprint library, the method being applied to a construction device, the method comprising:
step 101: receiving and storing real-time WIFI data and test WIFI data; real-time WIFI data are collected by fingerprint data collection equipment, test WIFI data are collected by test data collection equipment, and the fingerprint data collection equipment and the test data collection equipment are synchronously collected.
Specifically, when the fingerprint library is constructed, it is necessary to collect WIFI signals in a set Point of Information (POI). The POI here may be a house, a shop or a bus station. In this embodiment, the fingerprint data acquisition device and the test data acquisition device synchronously acquire WIFI signals in the same POI, and then transmit the WIFI signals to the construction device, and the construction device stores the received data. It should be noted that during signal acquisition, fingerprint data acquisition device and test data acquisition device are synchronous collection, and the real-time WIFI data that fingerprint data acquisition device gathered can be transmitted to the construction equipment by self, also can be transmitted to the construction equipment through test data acquisition device. The fingerprint data acquisition equipment is preset equipment, the test data acquisition equipment can be a mobile phone, and the construction equipment is a cloud server.
Step 102: and after the set test conditions are met, generating the real-time fingerprint data corresponding to all the real-time WIFI data. Here, the test condition is set to a preset time period. It should be noted that the specific duration of the preset time period is not unique, and may be set according to actual requirements.
Illustratively, the preset time period is 3 minutes, and after the preset time period is up to 3 minutes, the construction equipment generates corresponding real-time fingerprint data according to the real-time WIFI data received within the preset time period through a preset model. The preset model can be generated through a feature extraction algorithm, and the specific model generation process and the fingerprint generation process are not described in detail herein.
Step 103: and performing fingerprint quality verification on the real-time fingerprint and the tested WIFI data to obtain a verification result. The specific verification process is as follows: determining corresponding real-time acquisition positions according to all real-time fingerprint data; determining corresponding test acquisition positions according to all the test WIFI data; and selecting any one real-time acquisition position and any one test acquisition position for verification to obtain a verification result. Each fingerprint data only corresponds to a position, so the position corresponding to the real-time fingerprint and the position corresponding to the tested WIFI data are compared, and the accuracy of the real-time fingerprint, namely the accuracy of the fingerprint data acquisition equipment, can be known.
In more detail, when the real-time acquisition position and the test acquisition position are the same, the verification is passed, otherwise the verification is not passed. When the verification is passed, the data acquisition precision of the fingerprint data acquisition equipment can be indicated to be higher.
Wherein, more in detail, the process of determining the corresponding test acquisition position at the test WIFI data may be: and generating a test fingerprint according to the test WIFI data, and determining a corresponding test acquisition position according to the test fingerprint.
Because the fingerprint data acquisition equipment and the test data acquisition equipment acquire data in the same POI, when the positions are compared, any one group of the real-time acquisition positions and the test acquisition positions can be selected for comparison.
Step 104: and determining whether the real-time WIFI data acquisition process passes according to the verification result so as to construct a fingerprint library. Specifically, all verification results and the total verification group number are obtained; reading the number of groups passing the verification in the verification result; calculating verification passing proportion according to the number of groups and the total verification group number data; when the verification passing proportion is larger than or equal to the preset standard, determining that the data acquisition process passes; and if so, constructing a fingerprint database according to the real-time fingerprints. After the verification is finished, the verification passing number and the total verification number are counted in all the verification results, for example, the total verification number is 100, the verification passing number is 90, the percentage of the verification passing number in the total verification number is calculated to be 90%, the preset standard is 80%, and it is determined that the data acquisition process passes. It should be noted that the preset standard can be set according to actual requirements and is not fixed.
Now, taking an actual scenario as an example, a process of creating a fingerprint library in the present application is described in detail. Fig. 2 is a schematic diagram of an acquisition area according to an embodiment of the present invention. Referring to fig. 2, in the set acquisition area, the acquisition area is divided into a plurality of grids, a technician holds a fingerprint data acquisition device to acquire WIFI signals within each grid range, and when acquisition starts, the technician sends a synchronous acquisition instruction to a mobile phone of a test data acquisition device held by a user through the fingerprint data acquisition device to synchronously acquire the WIFI signals. When the real-time WIFI data are acquired by the fingerprint data acquisition equipment, the real-time WIFI data are transmitted to the test data acquisition equipment through wireless communication, the test data acquisition equipment uploads the real-time WIFI data and the test WIFI data acquired by the test data acquisition equipment to the construction equipment, the construction equipment receives and stores the real-time WIFI data and the test WIFI data, after the data are received for 5 minutes, all the real-time WIFI data and the test WIFI data received within 5 minutes are subjected to fingerprint generation to obtain position information corresponding to respective fingerprints, and positions and test acquisition positions are acquired in real time; and then randomly selecting one group from a plurality of real-time acquisition positions and test acquisition positions for comparison, if the positions of the real-time acquisition positions and the test acquisition positions are the same, judging that the fingerprint verification passes, sequentially executing the steps until all the real-time acquisition positions and the test acquisition positions are compared, calculating the verification passing rate, if the verification passing rate is more than 90%, determining that the data acquisition passes, and constructing a fingerprint database according to the fingerprint information acquired by the fingerprint data acquisition equipment.
In the above embodiment, the real-time WIFI data and the WIFI data are synchronously acquired and tested, so that the working efficiency of the construction of the fingerprint database is greatly improved. Meanwhile, data testing verification can be carried out when data are collected, problems occurring in collection can be known in time, the collection scheme is adjusted in time, the data collection efficiency is greatly improved, and the labor cost is reduced.
