Referring to fig. 3, fig. 3 is a flow chart illustrating a positioning method according to an exemplary embodiment of the present application. The method may be applied to the implementation environment shown in fig. 1, which may be performed by the positioning device 120 in the implementation environment shown in fig. 1.
As shown in fig. 3, in an exemplary embodiment, the positioning method may include S310-S330, which are described in detail below:
s310, detecting first positioning information of an object to be positioned.
It should be noted that, the object to be positioned is an object to be positioned, and its category includes, but is not limited to, an object, a person, and the like.
The first positioning information includes information for characterizing the position of the object to be positioned, which may be coordinates, longitude and latitude, or other information capable of characterizing the position of the object to be positioned.
When a certain object is required to be positioned, the positioning device can detect positioning information of the object to be positioned to obtain first positioning information.
Optionally, the positioning device may detect positioning information of the object to be positioned based on a wireless positioning technology, so as to obtain the first positioning information.
The wireless positioning technology is a technology for positioning based on wireless signals, for example, a device to be positioned can send wireless signals to a signal receiving device, the signal receiving device measures the received wireless signals to obtain measurement parameters, so that positioning is performed based on the measurement parameters, and optionally, in order to improve accuracy of indoor positioning, the device to be positioned can send wireless signals to a base station based on Ultra Wide Band (UWB) technology. Wireless location techniques include, but are not limited to, time difference of Arrival (Time Difference of Arrival, TDOA) location techniques, angle-of-Arrival (AOA) location techniques, and the like. The TDOA location is a technology for locating by using the signal arrival time difference, that is, the measurement parameter includes the signal arrival time; AOA positioning technology is a technology that uses the angle of arrival of a signal for positioning, i.e. the measured parameters include the angle of arrival of the signal.
Optionally, the object to be positioned may send a wireless signal to the positioning device through the terminal, and the positioning device measures the received wireless signal to obtain a measurement parameter, so as to detect positioning information of the object to be positioned based on the measurement parameter; or the object to be positioned can send a wireless signal to the base station through the terminal, the base station measures the received wireless signal to obtain a measurement parameter, the measurement parameter is sent to the positioning device, and the positioning device detects the positioning information of the object to be positioned based on the measurement parameter. The terminal comprises, but is not limited to, a mobile phone, a tablet computer, a work card capable of transmitting wireless signals and the like.
S320, if the first positioning information is matched with the set position characteristics, acquiring second positioning information of the object to be positioned; the second positioning information includes positioning information determined from scene data acquired at a target location corresponding to the first positioning information.
The set position features are preset data used for judging whether the second position information of the object to be positioned needs to be acquired or not, and the specific content of the set position features can be flexibly set according to actual needs. In one example, to improve the positioning accuracy of an area where a wireless signal is susceptible to interference, the set position feature may be a position where the object to be positioned enters the wireless positioning technology and is susceptible to interference, for example, an edge of the area, etc.; alternatively, the set position feature may be a feature that characterizes the entry of the object to be positioned into an area where positioning accuracy is required.
The target position is a position corresponding to the first positioning information, and optionally, the target position may be a position indicated by the first positioning information; alternatively, the position may be a position near the position indicated by the first positioning information, for example, a position where the distance from the position indicated by the first positioning information is smaller than a predetermined value.
The second positioning information contains information for characterizing the position of the object to be positioned, which may be coordinates, longitude and latitude, or other information capable of characterizing the position of the object to be positioned. In order to improve the positioning accuracy, scene data can be acquired at a target position, and the scene data acquired at the target position contains relevant data of an object to be positioned because the target position corresponds to the first positioning information; and then, determining the positioning information of the object to be positioned according to the acquired scene data, and taking the determined positioning information as second positioning information. Wherein scene data may be collected by at least one of infrared, radar, camera, etc.
Alternatively, the scene data may be collected by a data collection device. The data acquisition device may be a device mounted at or near the target location, for example, a camera fixed to a wall, or the like; alternatively, the data acquisition device may be a mobile device, such as a mobile robot or the like.
In order to improve the positioning accuracy, if the first positioning information of the object to be positioned is matched with the set position characteristic, the second positioning information of the object to be positioned is acquired.
S330, determining target positioning information of the object to be positioned according to the first positioning information and the second positioning information.
After the first positioning information and the second positioning information of the object to be positioned are obtained, the target positioning information of the object to be positioned can be determined according to the first positioning information and the second positioning information. Because the first positioning information and the second positioning information are determined based on different positioning technologies, the target positioning information of the object to be positioned is determined by combining the two positioning technologies, so that the positioning accuracy can be improved.
It should be noted that, the specific manner of determining the target positioning information of the object to be positioned according to the first positioning information and the second positioning information may be flexibly set according to actual needs. Optionally, the second positioning information is determined based on the scene data acquired by the target position corresponding to the first positioning information, so that the accuracy is higher, and the second positioning information can be used as the target positioning information; alternatively, an intermediate position between the position indicated by the first positioning information and the position indicated by the second positioning information may be used as the target positioning information.
Alternatively, in an example, if the first positioning information does not match the set position feature, the first positioning information may be directly used as the target positioning information.
In the embodiment shown in fig. 1, by detecting first positioning information of an object to be positioned, if the first positioning information is matched with a set position feature, obtaining second positioning information of the object to be positioned, where the second positioning information includes positioning information determined according to scene data acquired at a target position corresponding to the first positioning information, so that the second positioning information is determined according to the scene data of a scene where the object to be positioned is located, and accuracy of the second positioning information is improved; then, determining target positioning information of the object to be positioned according to the first positioning information and the second positioning information, thereby combining two different positioning technologies to determine the target positioning information of the object to be positioned, and further improving positioning accuracy; in addition, the second positioning information of the object to be positioned is acquired under the condition that the first positioning information is matched with the set position characteristics, so that the positioning accuracy in a specified scene can be improved, the amount of resources consumed by positioning can be reduced, and resources are saved.
In an exemplary embodiment, referring to fig. 4, fig. 4 is a flow chart of a positioning method shown in another exemplary embodiment of the present application. The method may be applied to the implementation environment shown in fig. 1, which may be performed by the positioning device 120 in the implementation environment shown in fig. 1. As shown in fig. 4, the positioning method includes S310, S410-S420, and S320-S330, which are described in detail as follows:
s410, acquiring historical positioning information of an object to be positioned; the time difference between the detection time of the historical positioning information and the detection time of the first positioning information is smaller than a preset time threshold.
It should be noted that the historical positioning information is the position information of the object to be positioned detected before the first positioning information is detected. The historical positioning information can be positioning information of an object to be positioned, which is detected based on a wireless positioning technology; alternatively, the historical positioning information may be positioning information of the object to be positioned detected based on other positioning technologies, for example, if the positioning device periodically determines target positioning information of the object to be positioned, the historical positioning information may be historical target positioning information.
The preset time threshold is used for acquiring the historical positioning information. The specific value of the method can be flexibly set according to actual needs, for example, the method can be set to be 2 seconds, 1 second and the like; in one example, if the positioning device periodically detects the position information of the object to be positioned based on the wireless positioning technology, or the positioning device periodically determines the target positioning information of the object to be positioned, the preset time threshold may also be 1 period, 2 periods, or the like.
In order to determine whether the first positioning information of the object to be positioned matches the set position feature, the positioning device may acquire historical positioning information in which a time difference between the detection time and the detection time of the first positioning information is smaller than a preset time threshold.
In step S420, if it is determined that the object to be positioned moves between the designated area and the adjacent area of the designated area according to the first positioning information and the historical positioning information, it is determined that the first positioning information matches with the set position feature.
The designated area may be an area designated from a plurality of areas divided in advance, and alternatively, an area requiring high positioning accuracy may be used as the designated area, for example, in order to ensure production and operation safety, strict management of a person or an object entering a key area (for example, a data center, a dangerous area) is required, and thus, the key area in production and operation may be set as the designated area. Alternatively, the specified area may be an area to which the position indicated by the first positioning information belongs.
Because the interval between the designated area and the adjacent area of the designated area is smaller, and an obstacle such as a wall may exist between the designated area and the adjacent area, and the obstacle has large interference on wireless signals, positioning is performed based on the wireless positioning technology, so that the object to be positioned in the designated area is easily positioned to the adjacent area of the designated area, or the object to be positioned in the adjacent area of the designated area is easily positioned to the designated area, and the positioning accuracy is reduced. Based on the above, in order to improve the positioning accuracy, whether the object to be positioned moves between the designated area and the adjacent area can be judged according to the acquired historical positioning information and the first positioning information, if so, the object to be positioned is characterized as moving between the designated area and the adjacent area of the designated area in a short time, the positioning error probability is higher, and in order to improve the positioning accuracy, the first positioning information is determined to be matched with the set position characteristics, so that the target positioning information of the object to be positioned is determined according to the first positioning information and the second positioning information.
Optionally, if the first positioning information matches with the set position feature and includes that the object to be positioned moves between the designated area and the adjacent area of the designated area, the corresponding second positioning information may include a detection result determined based on the scene data and representing whether the object to be positioned moves between the designated area and the adjacent area of the designated area.
It should be noted that: specific implementation details of S310-S330 shown in fig. 4 may refer to S310-S330 shown in fig. 3, and will not be described here again.
In the embodiment shown in fig. 4, the historical positioning information that the time difference between the detection time and the detection time of the first positioning information is smaller than the preset time threshold is obtained, if it is determined that the object to be positioned moves between the designated area and the adjacent area of the designated area according to the first positioning information and the obtained historical positioning information, the first positioning information is determined to be matched with the set position feature, so that the accuracy of the object to be positioned can be determined based on the first positioning information and the second positioning information, and the positioning accuracy in the designated area is improved.
In an exemplary embodiment, referring to fig. 5, fig. 5 is a flow chart of a positioning method shown in another exemplary embodiment of the present application. The method may be applied to the implementation environment shown in fig. 1, which may be performed by the positioning device 120 in the implementation environment shown in fig. 1. As shown in fig. 5, the positioning method includes S310, S510-S520, and S320-S330, which are described in detail as follows:
S510, obtaining the distance between the position indicated by the first positioning information and the boundary of the designated area.
For specific examples of the designated areas, please refer to the foregoing descriptions, and no further description is given here.
After the first positioning information of the object to be positioned is detected, a distance between the position indicated by the first positioning information and the boundary of the designated area may be acquired.
And S520, if the acquired distance is smaller than a preset distance threshold, determining that the first positioning information is matched with the set position feature.
If the distance between the position indicated by the first positioning information and the boundary of the designated area is smaller, the fact that the object to be positioned is located near the boundary of the designated area is indicated, and the positioning error probability is higher, so that in order to improve the positioning accuracy, the first positioning information is determined to be matched with the set position characteristics, and the target positioning information of the object to be positioned is determined according to the first positioning information and the second positioning information.
It should be noted that: specific implementation details of S310-S330 shown in fig. 5 may refer to S310-S330 shown in fig. 3, and will not be described here again.
In the embodiment shown in fig. 5, if the distance between the location indicated by the first positioning information and the boundary of the designated area is smaller than the preset distance threshold, it is determined that the first positioning information is matched with the set location feature, so that the accuracy of the object to be positioned can be determined based on the first positioning information and the second positioning information, and the positioning accuracy of the edge of the designated area is improved.
In an exemplary embodiment, referring to fig. 6, fig. 6 is a flow chart of a positioning method shown in another exemplary embodiment of the present application. The method may be applied to the implementation environment shown in fig. 1, which may be performed by the positioning device 120 in the implementation environment shown in fig. 1. As shown in fig. 6, the positioning method includes S310, S610-S620, and S330, which are described in detail as follows:
s610, if the first positioning information is matched with the set position characteristics, acquiring authority information of the object to be positioned.
In this embodiment, corresponding rights are set for different objects.
In order to determine whether the object to be positioned has the authority to enter the designated area, if the first positioning information is matched with the set position characteristics, acquiring the authority information of the object to be positioned.
S620, if the object to be positioned is determined to not have the authority to enter the designated area according to the authority information, second positioning information is acquired.
If the object to be positioned does not have the authority to enter the instruction area according to the authority information of the object to be positioned, in order to more accurately acquire the position of the object to be positioned, whether the object to be positioned enters the designated area or not is determined, second positioning information is acquired, and therefore target positioning information of the object to be positioned is determined according to the first positioning information and the second positioning information.
Optionally, if it is determined that the object to be positioned has the authority to enter the designated area according to the authority information of the object to be positioned, in order to save resources, the second positioning information may not be acquired, and the first positioning information may be directly used as the target positioning information of the object to be positioned; of course, in other examples, in order to make the acquired position information more accurate, even if the authority information of the object to be positioned determines that the object to be positioned has the authority to enter the instruction area, the second positioning information may be acquired so as to determine the target positioning information of the object to be positioned according to the first positioning information and the second positioning information.
Optionally, after determining that the object to be located does not have the authority to enter the designated area according to the authority information and determining the target location information, if determining that the object to be located is located in the designated area according to the target location information, an alarm can be performed, and a specific alarm mode can be flexibly set according to actual needs, for example, a short message can be sent to a manager to prompt and the like.
It should be noted that: specific implementation details of S310 and S330 shown in fig. 6 may refer to S310 and S330 shown in fig. 3, and are not described herein.

The object detection data may include a mobile robot number, a data acquisition position of the mobile robot, a data acquisition time, an ID of at least one object (for example, an ID of a UWB terminal carried by the object), position information of at least one object, and acquired data.
S1702, the robot control device determines positioning information of at least one object according to the object detection data, and transmits the positioning information of the at least one object to the UWB positioning device.
The robot control device may determine, according to the map, a wall body and an area to which each object corresponds according to position information of at least one object in the object detection data, and determine positioning information of each object according to the area number and the wall body number, where the positioning information may include an ID of the object, position information, the area number, the wall body number, a position detection time, and the like.
S1703, the UWB positioning device stores positioning information of at least one object.
The UWB positioning device may store positioning information of at least one object to a database.
S1704, the UWB terminal transmits the UWB positioning reference signal outwards.
In order to enable the UWB positioning device to position the UWB terminal and thus the object to be positioned, in this embodiment, the UWB terminal may send an UWB positioning reference signal to the outside based on UWB technology, and the UWB positioning reference signal is used to measure the position of the UWB terminal.
Optionally, the UWB positioning reference signal may be a periodic nanosecond pulse signal, which is mainly used for measuring accurate arrival time and arrival angle by the UWB base station.
