Although the purpose of target finding can be achieved by performing technical improvement in the missing space of the positioning equipment in the prior art, the construction cost is greatly increased. The invention can better finish the aim of target searching under the condition of lacking the positioning equipment, reduce the cost and improve the economic benefit.
The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
In one embodiment, the present invention provides a method for object finding, which can be performed by any device performing the method for object finding or navigating, and the device performing the method for object finding or navigating is implemented by hardware and/or software. As shown in fig. 2, the method for target acquisition provided by this embodiment includes the following steps:
step S101: and acquiring a map of a space where the main body and the target searched by the main body are located together.
In this step, a map of a space where the subject and the target sought by the subject are located together is obtained, and the map may be a brief spatial arrangement map (including a main environmental target which can be advantageously sought by the target and is identified by the subject, and does not have to be too comprehensive), or may be a detailed map; the map obtained in this step may be a two-dimensional map, a three-dimensional map, or a combination of a two-dimensional map and a three-dimensional map.
The targets in this embodiment may be various fixtures, markers, stores, books, vehicles, articles, and the like.
Alternatively, a map of a common space in which both the subject and the target are located is obtained by scanning the identification two-dimensional code. The two-dimensional code is generated by map software in advance, when the terminal equipment calls the camera to scan and identify the two-dimensional code, and then the two-dimensional code is decoded, the map of the common space where the main body and the target are located can be obtained, and the method has the advantages of simplicity, high efficiency and safety.
Optionally, the terminal device is provided with target searching software, and after the main body opens the target searching software, a map of a space where the main body and the target searched by the main body are located together can be obtained.
Step S102: an initial position and a direction of movement of the subject on the map and a current position of the target on the map are determined.
In this step, the initial position refers to the position of the main body on the map when the main body starts to search for the target, and the initial position of the main body is kept unchanged in the process of searching for the target by the main body; the current position of the target on the map may remain the same during the process of the subject seeking the target, or may change with the movement of the target.
The initial position and the movement direction of the main body on the map can be determined by scanning and identifying the two-dimensional code or by placing a positioning mark and a direction mark on the map by the main body. When the main body obtains the map and the initial position of the main body by scanning and recognizing the two-dimensional code, the movement direction of the main body can also be obtained by scanning and recognizing the two-dimensional code or obtained by artificially placing a direction mark in a complex environment. Optionally, there are two ways to determine the initial position of the subject on the map:
the first method is as follows: the two-dimensional code is scanned and identified to obtain the map, and meanwhile, the two-dimensional code is accompanied with position information and direction information, so that the current position of the main body can be obtained through scanning and identifying the two-dimensional code, and the initial position of the main body on the map is determined according to the current position of the main body. The initial position and the movement direction of the main body on the map are determined by scanning and identifying the two-dimensional code, and the method has the advantages of being simple to operate and convenient to position.
The second method comprises the following steps: the method comprises the steps of obtaining a map by scanning and identifying the two-dimensional code, determining an initial position according to a first positioning identifier of a main body placed on the map, and determining a movement direction according to a direction identifier of the main body placed on the map. After obtaining the map through scanning discernment two-dimensional code, the main part full play self subjective initiative, confirm self perception and map to the environmental position in place space contrast, place first location sign (or drawing pin) on the map and confirm the current position of main part, thereby can confirm the initial position of main part according to first location sign, simultaneously, the main part is placed direction sign (or drawing pin) on the map and is confirmed the direction that the main part will advance, thereby can confirm the direction of motion of main part according to the direction sign. Under the determination mode, the main body fully exerts the subjective activity of the main body, and the participation degree of the main body is improved.
When the main body does not scan the two-dimensional code in time and enters a space environment where the main body and the target are located together, the main body obtains a map of the space where the main body and the target located by the main body are located together by opening target locating software, then after the main body synthesizes the environment and the map through subjective cognition, positioning marks are manually placed on the map to determine an initial position, and meanwhile, a direction mark is placed to show a direction to be traveled.
Optionally, the current position of the target on the map is determined by any one of the following three ways:
the first method is as follows: local query
Acquiring the name of a target;
searching the position of the data element matched with the acquired name in a first database, wherein the first database is a database which is established after environmental data of a space where the target is located is collected in advance, the environmental data can be any form which is beneficial to target acquisition and is identified by a subject, and the position of the data element matched with the acquired name comprises but is not limited to: a schematic space layout diagram (which can be a three-dimensional and/or two-dimensional diagram) required for target searching in the space, various labels, various placing objects (or racks) capable of being identified by the subject, markers, any other form of two-dimensional codes with existence and positioning positions capable of being identified by the subject, and the like;
and taking the position of the data element as the current position of the target on the map, thereby determining the current position of the target sought by the main body on the map.
The second method comprises the following steps: other terminal device transmitting
Receiving the positions of targets sent by other terminal equipment;
and taking the position of the received target as the current position of the target on the map, thereby determining the current position of the target sought by the main body on the map.
In the method, the terminal device held by the main body receives the target position sent by other terminal devices through a system channel, and the terminal device held by the main body can determine the current position of the target on the map according to the received target position.
The third method comprises the following steps: subject input
After the map is obtained by scanning and identifying the two-dimensional code, the main body gives full play to the subjective initiative of the main body, the position of the searched target on the map is judged by checking and comparing, then the second positioning identifier (or the drawing pin) is placed on the map to confirm the current position of the target, and the position of the second positioning identifier placed in the map by the main body is obtained and is taken as the current position of the target on the map, so that the current position of the searched target of the main body on the map is determined.
Step S103: and determining the dynamic mapping position of the main body on the map in the process of finding the target.
After the initial position of the main body on the map and the current position of the target on the map are determined in step S102, the main body can start target retrieval, and in the process of retrieval, the dynamic mapping position of the main body is displayed on the map in real time, so that the main body can view the dynamic mapping position in real time, and the accurate navigation of the target to be retrieved is realized.
In this step, in the process of target finding, the dynamic mapping position of the subject on the map may be obtained by calculating vector points formed by three basic quantities, that is, the initial position is the base point, the movement direction determined by the direction determining means (for example, a gyroscope or the like), and the movement distance determined by the movement measuring means (for example, a gravity sensor or the like). Specifically, the dynamic mapping position of the main body on the map in the process of finding the target is determined through the following steps:
acquiring movement direction data and movement distance data of a main body in the process of searching for a target, wherein the movement direction data can be measured by using a direction determining device (such as a gyroscope and the like), and the movement distance data can be measured by using a movement measuring device (such as a gravity sensor and the like);
next, with the initial position as a base point, a movement vector is calculated according to the movement direction data and the movement distance data, and then a corresponding vector point is calculated according to the movement vector, and a dynamic mapping position of the subject on the map can be determined according to the calculated vector point, as shown in fig. 3, a deviation may exist between an actual movement track of the subject and the movement vector, but the vector point corresponding to the movement vector can accurately reflect the dynamic mapping position of the subject on the map.
Optionally, in this step, the salient intermediate target and the position of the salient intermediate target in the space where the target is known may be pre-recorded in the database, and then the dynamically mapped position of the subject in the target retrieval process may be presented on the map of the terminal device by using the augmented reality technology. Specifically, the dynamic mapping position of the main body on the map in the process of finding the target can be further determined through the following steps:
the method comprises the steps of scanning and acquiring a remarkable intermediate target in a space where the target is located by utilizing an augmented reality technology, wherein the remarkable intermediate target can be various environmental targets which can be favorably searched by the target and are identified by a subject;
comparing the obvious intermediate target with a second database to obtain the position of the obvious intermediate target, wherein the second database records the obvious intermediate target in the space where the target is located and the position of the obvious intermediate target in advance;
and taking the position of the obvious middle target as the dynamic mapping position of the subject on the map.
The 'virtual' in the terminal held by the main body is roughly superposed with the 'real' seen by the main body by utilizing the augmented reality technology so as to determine the dynamic mapping position of the main body on the map, and the cognitive ability of the main body to the environment is fully utilized.
Alternatively, in this step, the dynamic mapping position of the subject may be determined using a two-dimensional code whose position is fixed in advance. Specifically, the dynamic mapping position of the main body on the map in the process of finding the target can be further determined through the following steps:
scanning a two-dimensional code with a position in a space where an identification target is located fixed in advance to obtain the position of the two-dimensional code, wherein the position of the two-dimensional code is fixed and known in advance, and the two-dimensional code is placed at a position which is obvious and beneficial to a main body to know as much as possible so as to be convenient for the main body to know and scan and identify;
after the two-dimensional code is scanned and identified and the position of the two-dimensional code is obtained, the position of the two-dimensional code is taken as the dynamic mapping position of the main body on the map, and the dynamic mapping position of the main body on the map changes along with the scanning and identification of the two-dimensional code at different positions in the process of searching the target by the main body, so that the navigation is provided for the main body.
In another embodiment, as shown in fig. 4, the method for target acquisition provided by this embodiment includes the following steps:
step S201: obtaining a map of a common space where a main body and a target searched by the main body are located;
step S202: determining an initial position and a movement direction of a subject on a map and a current position of a target on the map;
step S203: determining a dynamic mapping position of a main body on a map in the process of finding a target;
steps S201 to S203 are similar to steps S101 to S103, and are not described herein again.
In this embodiment, after step S203, the method further includes:
step S204: and generating corresponding sound and/or visual prompt information according to the dynamic mapping position.
After determining the dynamic mapping position of the main body on the map in the process of searching the target, the step generates corresponding sound and/or visual (such as lamplight, images and the like) prompt information according to the dynamic mapping position, so that the user can complete target searching according to the prompt information, the target searching efficiency is further improved, and the target searching experience is improved.
