The sequence numbers of the above-described embodiments are merely descriptive and do not represent the superiority or inferiority of the embodiments.

[0044] Unless otherwise specified, any step in the embodiments of this application performed by the electronic device may be executed by the processor of the electronic device. It is also worth noting that the embodiments of this application do not limit the order in which the electronic device performs the following steps. Furthermore, the methods used to process data in different embodiments may be the same or different methods. It should also be noted that any step in the embodiments of this application can be executed independently by the electronic device; that is, when the electronic device performs any step in the following embodiments, it may not depend on the execution of other steps.

[0045] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application.

[0046] This application provides an information determination method, referring to... Figure 1 As shown, the method may include the following steps:

[0047] Step 101: Determine the reference position information of the driving equipment based on the first signal received by the first antenna of the driving equipment.

[0048] In this embodiment, the driving device can be a car, ship, or drone, etc.; the first antenna can refer to an antenna installed on the driving device. Specifically, the first signal received by the driving device can be processed to obtain the first Global Positioning System Fix Data (GGA) for the driving device, and the reference position information of the driving object can be determined based on the first GGA data.

[0049] Step 102: Determine the approximate location information of the target device based on the second signal received by the second antenna of the target device mounted on the driving equipment.

[0050] The first antenna is located within a planar region formed by multiple second antennas.

[0051] In this application embodiment, the target device may refer to a real-time kinematic (RTK) mapping device installed on a driving device; the second antenna may refer to the antenna of the RTK mapping device itself.

[0052] Each RTK mapping device may have one second second line of sight or two second second lines of sight. It should be noted that the number of second second lines of sight in this invention is at least two, that is, the driving equipment is equipped with at least two RTK mapping devices with one second second line of sight, or at least one RTK mapping device with two second second lines of sight.

[0053] In this embodiment, the planar area formed by the second second line can be a line segment, a triangle, or a rectangle, etc., and can be determined according to the number of second second lines.

[0054] Step 103: Based on the reference position information and the preliminary position information, determine the target error of the position of the traveling equipment.

[0055] In the embodiments of this application, the target position of the driving device can be determined based on multiple preliminary position information, and the positioning error of the driving device, i.e., the target error of the position of the driving device, can be determined based on the target position and reference position information.

[0056] The information determination method provided in the embodiments of this application can determine the positioning error of a driving vehicle by combining reference position information determined based on the signal received by the first antenna and multiple approximate position information determined based on the signals received by multiple second antennas. That is, multiple approximate positions are considered when determining the positioning error of the driving vehicle, rather than relying solely on a single positioning position as in related technologies. This solves the problem of low accuracy in determining the positioning error in related technologies. Furthermore, by placing the first antenna within the planar area formed by multiple second antennas, the problem of additional errors introduced by the adjacent placement of the vehicle's antenna and the surveying equipment's antenna in related technologies can also be solved, further improving the accuracy of the determined vehicle positioning error.

[0057] Based on the foregoing embodiments, embodiments of this application provide an information determination method, which can be applied to an information determination device, with reference to... Figure 2 As shown, the method may include the following steps:

[0058] Step 201: The information determining device determines the reference position information of the driving device based on the first signal received by the first antenna of the driving device.

[0059] In this embodiment, the reference location information may include latitude and longitude information, altitude information, and data recording time. Specifically, the first signal can be processed according to the National Marine Electronics Association (NMEA) protocol to obtain first GGA data, and then the reference location information can be extracted from the first GGA data. The altitude information may include a first altitude and a second altitude; the data recording time may refer to Coordinated Universal Time (UTC).

[0060] It should be noted that the traveling equipment has only one first antenna, and the installation position of the first first antenna needs to be determined based on the number and installation position of the second second antenna of the RTK mapping equipment mounted on the traveling equipment.

[0061] For example, the first GGA data can be shown in Table 1 below.

[0062]

[0063] Table 1

[0064] It should be noted that, in addition to UTC time, longitude, latitude, and altitude information, GGA data may also include positioning quality indication, horizontal accuracy factor, number of satellites, and other information.

[0065] Step 202: The information determining device determines the approximate position information of the target device based on the second signal received by the second antenna of the target device mounted on the driving device.

[0066] The first antenna is located within a planar region formed by multiple second antennas.

[0067] In this embodiment, if there are two second antennas, the first antenna is set on the line segment formed by the installation points of the two second antennas, that is, the installation position of the first antenna and the installation positions of the two second antennas are on the same straight line; if there are three second antennas, the first antenna will be located in the triangular area or circular area formed by the three second antennas; if there are four second antennas, the second antennas will be located in the rectangular area or circular area formed by the four second antennas.

[0068] It should be noted that if there are two second antennas, the first antenna can preferably be placed in the middle of the two second antennas, even if the center of the second antenna coincides with the center of the line segment formed by the two antennas.

[0069] In this embodiment, the preliminary location information may include the latitude and longitude information, altitude information, and data recording time corresponding to the second antenna. Specifically, at least two second signals received from at least two second antennas can be processed according to the NMEA protocol to obtain multiple second GGA data. Then, preliminary location information can be extracted from each second GGA data. It should be noted that each second antenna corresponds to one preliminary location information.

[0070] Step 203: The information determination device determines the target position of the traveling device based on multiple preliminary position information.

[0071] In this embodiment, the target location may refer to the theoretical location of the driving device. Specifically, the distance between the first antenna and each second antenna can be determined, and the target location of the driving object can be determined based on multiple distances and multiple preliminary location information.

[0072] In the embodiments of this application, step 203 can be implemented by steps 203a to 203c.

[0073] Step 203a: The information determination device determines the distance between the first antenna and each second antenna.

[0074] In the embodiments of this application, if there are two second antennas, two distances can be determined; if there are three second antennas, three distances can be determined.

[0075] In one feasible approach, if there are two second antennas and the first antenna is located at the midline between the two second antennas, two distances can be obtained, and the two distances obtained are equal.

[0076] Step 203b: The information determination device filters multiple preliminary location information based on the target parameters to obtain multiple first location information.

[0077] In this embodiment, the target parameter can characterize whether the preliminary location information is missing any necessary field information. In one possible implementation, the target parameter can be carried in the preliminary location information and can be represented by a numerical value. For example, 0 can indicate that the preliminary location information contains all necessary field information; 1 can indicate that the preliminary location information is missing some necessary information.

[0078] In this embodiment of the application, multiple preliminary location information can be filtered according to the target parameters in each preliminary location information to obtain multiple first location information (i.e., fixed solutions) containing all necessary field information, that is, the preliminary location information lacking necessary information is removed from all preliminary location information.

[0079] Step 203c: The information determining device determines the target position of the traveling device based on multiple first position information and multiple distances.

[0080] In the embodiments of this application, step 203c can be implemented by steps 203c1 to 203c2.

[0081] Step 203c1: The information determination device determines the weight corresponding to each distance.

[0082] In this embodiment, the weight represents the importance corresponding to each distance. If multiple distances are equal, then the weight corresponding to each distance is also equal. It should be noted that the weight can be determined based on historical data and actual needs.

[0083] Step 203c2: The information determination device determines the target location based on multiple first location information, multiple distances, and multiple weights.

[0084] In this embodiment of the application, multiple first coordinates can be obtained by processing the first position information, and the target position of the driving object can be determined based on the multiple first coordinates, multiple distances and the weight corresponding to each distance.

[0085] In the embodiments of this application, step 203c2 can be implemented by steps 203c21 to 203c23.

[0086] Step 203c21: The information determining device determines multiple first coordinates based on multiple first position information, and performs format conversion on each first coordinate to obtain multiple second coordinates.

[0087] In the embodiments of this application, the latitude, longitude and altitude information in each first location information can be converted into geodetic coordinates in the geodetic coordinate system, namely BLH coordinates.

[0088] For example, if the first location information is as shown in Table 2 below, then the first coordinates obtained after converting the latitude, longitude and altitude information can be (31.250489718, 121.612116071, 51.400299999).

[0089]

[0090] Table 2

[0091] Then, the obtained first coordinates can be transformed again to convert them into coordinates in a spatial rectangular coordinate system. For example, after transforming the first coordinates (31.250489718, 121.612116071, 51.400299999), we can obtain its second coordinates in a spatial rectangular coordinate system (-2860729.990282290, 4647847.671791870, 3289694.259323440).

[0092] It should be noted that one first coordinate corresponds to one second coordinate.

[0093] Step 203c22: The information determination device determines the reference coordinates based on multiple second coordinates, multiple distances, and multiple weights.

[0094] The target location includes the reference coordinates.

[0095] In this embodiment, each distance and its corresponding weight can be calculated first to obtain multiple values. Then, the reference coordinates can be determined based on the multiple values ​​and multiple second coordinates. In one feasible approach, if there are two second antennas, that is, two second coordinates, two distances and two weights, the formula for calculating the reference coordinates can be as shown in formulas (1) to (3) below.

[0096]

[0097] Where d1 represents the first distance from the first antenna to the first second antenna; d2 represents the second distance from the first antenna to the second second antenna; a represents the weight corresponding to the first distance; b represents the weight corresponding to the second distance; x1 represents the x-coordinate of the first second coordinate system corresponding to the first second antenna; x2 represents the x-coordinate of the second second coordinate system corresponding to the second second antenna; y1 represents the y-coordinate of the first second coordinate system corresponding to the first second antenna; y2 represents the y-coordinate of the second second coordinate system corresponding to the second second antenna; z1 represents the vertical coordinate of the first second coordinate system corresponding to the first second antenna; z2 represents the vertical coordinate of the second second coordinate system corresponding to the second second antenna; x c y represents the x-coordinate in the reference coordinate system. c z represents the ordinate in the reference coordinate system. c This represents the vertical coordinate in the reference coordinate system.

[0098] It should be noted that the reference coordinates are coordinates in a spatial rectangular coordinate system.

[0099] Step 204: The information determination device determines the target error of the position of the traveling device based on the reference position information and the target position.

[0100] In this embodiment of the application, reference coordinates can be determined based on reference position information, and the positioning error of the driving device, i.e. the target error of the position of the driving device, can be determined based on the reference coordinates and the reference coordinates in the target position.

[0101] In the embodiments of this application, step 204 can be implemented by steps 204a to 204b.

[0102] Step 204a: The information determination device performs format conversion on the reference coordinates to obtain the converted coordinates.

[0103] In the embodiments of this application, the coordinates in the spatial rectangular coordinate system can be transformed to obtain the geodetic coordinates in the geodetic coordinate system, namely the BLH coordinates (transformed coordinates).

[0104] Step 204b: The information determining device determines the reference coordinates based on the reference position information, and determines the target error based on the reference coordinates and the transformed coordinates.

[0105] In this embodiment, the target error may include horizontal error and elevation error. Specifically, the latitude, longitude, and altitude information in the reference location information can be converted into geodetic coordinates in a geodetic coordinate system, i.e., reference coordinates. Based on the obtained reference coordinates and the converted coordinates, the horizontal and elevation errors of the position of the traveling equipment can be determined.

[0106] In the embodiments of this application, step 204b can be implemented through steps 204b1 to 204b2.

[0107] Step 204b1: The information determination device determines the horizontal and vertical errors of the position based on the reference coordinates and the transformed coordinates.

[0108] In this embodiment, the reference coordinates can be converted into coordinates in a spatial rectangular coordinate system, i.e., the converted reference coordinates are obtained. Then, the horizontal error and the elevation error are determined based on the reference coordinates, the converted reference coordinates, the datum coordinates, and the converted coordinates. It should be noted that the reference coordinates, the converted reference coordinates, the datum coordinates, and the converted coordinates all correspond to the same UTC time.

[0109] Specifically, the reference coordinates (X, X) of point i can be determined according to the following formula (4). i ,Y i Z i ), transformed reference coordinates (B) i ,I i H i ) and the reference coordinates (X) of point j j ,Y j Z j ), transformed coordinates (B) j,I j H j ) Perform the calculation to obtain the station center coordinates (e) of point j relative to point i. j ,n j ,u j ).

[0110]

[0111] Then, the obtained station center coordinates can be calculated according to formula (5) to obtain the azimuth angle d of point j relative to point i. j .

[0112]

[0113] Furthermore, the station center coordinates (e) of point i relative to point j can be calculated using formulas (4) and (5). i ,n i ,u i ) and azimuth d i Then, the horizontal error herr of the position of the traveling equipment at point j can be calculated according to formulas (6) and (7). j and elevation error lerr j .

[0114]

[0115] lerr j =|herr*cos(d j -d i -π)| Formula (7)

[0116] Then, similarly, the horizontal error herr of the position of the driving device at point i can be calculated according to formulas (6) and (7). i and elevation error lerr i .

[0117] Step 204b2: The information determination device determines the target error based on multiple horizontal errors and multiple elevation errors.

[0118] In this embodiment of the application, the horizontal and vertical errors of the position of the driving device at each UTC time can be calculated according to step 204b3, and the multiple horizontal and vertical errors obtained can be statistically analyzed to obtain the target error including the standard deviation 1 sigma, two times the standard deviation 2 sigma, three times the standard deviation 3 sigma and the circular probability error (CEP) value.

[0119] It should be noted that the descriptions of the same steps and contents as in other embodiments in this embodiment can be found in the descriptions in other embodiments, and will not be repeated here.

[0120] The information determination method provided in the embodiments of this application can determine the positioning error of a driving vehicle by combining reference position information determined based on the signal received by the first antenna and multiple approximate position information determined based on the signals received by multiple second antennas. That is, it considers multiple approximate position information when determining the positioning error of the driving vehicle, rather than determining the positioning error based solely on a single positioning position as in related technologies. This solves the problem of low accuracy in determining the positioning error in related technologies. Furthermore, by placing the first antenna within the planar area formed by multiple second antennas, it also solves the problem of additional errors introduced by the adjacent placement of the vehicle's antenna and the surveying equipment's antenna in related technologies, further improving the accuracy of the determined vehicle positioning error.

[0172] The information determination device provided in the embodiments of this application can determine the positioning error of a driving vehicle by combining reference position information determined based on the signal received by the first antenna and multiple approximate position information determined based on the signals received by multiple second antennas. That is, it considers multiple approximate position information when determining the positioning error of the driving vehicle, rather than determining the positioning error based solely on a single positioning position as in related technologies. This solves the problem of low accuracy in determining the positioning error of vehicles in related technologies. Furthermore, by placing the first antenna within the planar area formed by multiple second antennas, it also solves the problem of additional errors introduced by the adjacent placement of the vehicle's antenna and the surveying equipment's antenna in related technologies, further improving the accuracy of the determined vehicle positioning error.
