Embodiment A

[0091]Embodiment A, a positioning method based on finding the distance between the host and the target:

[0092] In embodiment A, the first associated data may specifically be the first distance data between the host and the target obtained in the first movement track. Correspondingly, step 203 specifically includes:

[0093] Step 203A1, according to the first distance data and the coordinate data of multiple positions, calculate the coordinate data of the object to be found;

[0094] Step 203A2, based on the coordinate data of the target and the current coordinate data of the search host, determine the direction of the target.

[0095] image 3 It shows a schematic diagram of a first movement trajectory for finding a host provided by the embodiment of the present application. The first movement trajectory contains n times of distance measurement, and there are n distance measurement distances d 1 -d n and n ranging moments to find host coordinates: P 1 -P n .

[0096] A...

Embodiment B

[0120] The first associated data may specifically be the first signal strength value between the host and the target obtained in the first movement track, and step 203 may specifically include:

[0121] Step 203B1, arranging the order of multiple positions according to the magnitude of the first signal strength value;

[0122] Step 203B2, determine the direction of the object to be found according to the coordinate data corresponding to the arranged positions.

[0123] In embodiment B, after arranging a plurality of first signal strength values ​​(such as RSSI values) in order of size, the distance to the target is closer if the signal strength value is large, and the distance to the target is farther if the signal strength value is small According to the coordinate data corresponding to the arranged position, the direction of the object to be found is determined.

[0124] Correspondingly, the second associated data includes the second signal strength value between the search...

Embodiment C

[0128] Specifically, the first associated data may be the first direction data between the search host and the target obtained in the first movement track, and step 203 may specifically include:

[0129] Step 203C1, according to the first direction data, determine the direction of the sought object.

[0130] Correspondingly, the second associated data includes third distance data and / or third signal strength values ​​between the searching host and the searched object acquired in the second movement trace, and the preset The item finding success condition includes a preset distance threshold and / or a preset signal strength threshold, step 205, specifically includes:

[0131] Step 205C1, when the third distance data is less than or equal to the preset distance threshold and / or the third signal strength value is less than or equal to the preset signal strength threshold, output a search success prompt message, wherein the The finding success prompt information is used to prompt ...

Abstract

The invention discloses a target searching method and device, a storage medium and a computer equipment. The method comprises the steps: obtaining first associated data between a searching host and asearched target at multiple positions; and outputting first prompt information according to the first associated data corresponding to each position, wherein the first prompt information is used for prompting a holder of the searching host to move towards the direction in which the searched target is located. Compared with a mode of realizing target positioning by utilizing a plurality of base stations built at different positions in the prior art, the method has the advantages that only one portable searching host is needed, the method can be suitable for indoor scene positioning, and the holder of the searching host can be guided to move towards the direction of the target, so the target is more convenient to search.

Description

technical field [0001] The present application relates to the technical field of positioning, and in particular to a method, device, storage medium and computer equipment for finding a target. Background technique [0002] Location-based service (Location-based service, LBS), also known as positioning service, refers to mobile terminals, such as mobile terminals and operators' mobile communication networks (such as GSM network, CDMA network) to cooperate with each other, and judge mobile terminals through base stations that transmit mobile terminal signals. The location of the terminal determines the geographical location information (latitude and longitude coordinates) of the mobile terminal user, so as to provide the location-related service information required by the user. The positioning process only takes a few seconds, and the traffic cost is only a few tens of bytes. Due to the regional and convenient characteristics of consumers' demand for life services, location-...
