Description
Technical field
The invention belongs to wireless location, location-based service and internet of things field, especially a kind of positioning dimension determines method, determines
Position system and localization method.
Background technique
As the wireless sensors such as GNSS, WiFi, BLE are in the universal of the mobile terminals such as smart phone and wearable target,
And extensive use has been obtained in the demand of location-based service, Internet of Things to location information, wireless location system and technology.Mainstream
Wireless location technology include polygon intersection, fingerprint recognition etc..For most of generic wireless location applications, it is based on mesh
The signal strength of (such as mobile terminal) with respect at least three wireless base stations is marked, it can be in wireless base station information (such as coordinate and wireless
Signal propagation attenuation model parameter) known in situation, position and the precision of target are calculated using polygon crossing location；Or
In the case where wireless base station information is unknown, the position of target is calculated using fingerprint recognition.
For different positioning applications, it may be necessary to select different positioning system and method.Therefore, positioning application needs
The compromise of performance and cost (including hardware cost, calculating cost etc.).Polygon (with respect to three wireless bases at least three sides, i.e. target
The distance stood) intersection and fingerprint recognition have become the mainstream technology of current wireless location, can in most cases,
The location information of three-dimensional space is provided.But then, currently still there are some positioning to apply, do not need three-dimensional localization.Such as:
Zero dimension positioning application: it swipes the card, cattle and sheep fixed point feeding, point of interest detection, shake periphery etc.；
One-dimensional positioning application: it is positioned in such as airdrome luggage inspection, tunnel；
Two-dimensional localization application: application etc. in most of outdoor utilities, single floor.
In comparison, high-dimensional and (such as compared for three-dimensional localization, two-dimentional, one-dimensional and zero dimension is positioned as compared with low dimensional
Compared with low dimensional) localization method it is each advantageous.For example, high-dimensional localization method is more pervasive, i.e. methodology and system is
Can meet the needs of positioning in most three-dimensional space.On the other hand, there is following advantage using the localization method compared with low dimensional:
First, calculation amount is lower, and correspondingly power consumption is lower.Second, the number of required base station is lower, and then less in number of base stations
In the case of availability it is stronger.Third, location parameter to be calculated is less, in the same number of situation of observation, special parameter
Estimated accuracy may be higher.
The prior art sets generally directed to the positioning application of specific dimension and uses different localization method or algorithm.Positioning
The selection of method generally determines before positioning product produces and burning.For example, for above-mentioned zero dimension application, usually using RFID or
Person's Bluetooth technology needs to be previously set to use zero dimension location algorithm, i.e., target is navigated to the periphery of some base station；For upper
One-dimensional or two dimensional application is stated, is usually also required to that the dimension of positioning is previously set, to select corresponding location algorithm.
With low cost positioning application, such as in face of the universal of the positioning service of Internet of Things, it is sometimes desirable to automatic according to application
Switching positioning dimension.For example, it can be switched to the localization method compared with low-dimensional according to the actual situation sometimes in higher-dimension application, thus
Achieve the purpose that the estimated accuracy for reducing calculation amount, improving special parameter.For example, sometimes, being visited in three-dimensional localization application
Target is measured to be near a base station or between two base stations.At this time, zero dimension or one-dimensional positioning method is used only
The position of target can be obtained.
