Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication technology, and in particular to a roaming test method, apparatus, terminal device, and storage medium. Background Art

[0002] A wireless access point (AP) is an access point for wireless devices to access a wired network. In implementation, multiple APs need to be deployed in some areas, and after deployment, roaming tests are required to evaluate the deployment of APs.

[0003] In the related art, a tester carries a mobile phone and moves around a deployment area, interacts with an AP, performs a roaming test, and obtains a roaming test result; and then evaluates whether the deployment of the AP is reasonable based on the roaming test result.

[0004] However, in the above method, testers can only rely on experience to carry mobile phones and move around the deployment area, which may result in detection blind spots. In addition, the above method can only obtain the changes in roaming test data over time, but cannot determine the location corresponding to the roaming test data, making it difficult to accurately evaluate the deployment of APs. Summary of the invention

[0005] Embodiments of the present application provide a roaming test method, apparatus, terminal device, and storage medium for obtaining a moving track in a roaming test.

[0006] In a first aspect, an embodiment of the present application provides a roaming test method, which is applied to a terminal device. The method includes:

[0007] Performing augmented reality (AR) positioning at the trajectory point of the terminal device to obtain AR coordinates of the trajectory point; and determining detection data corresponding to the trajectory point; wherein the AR coordinates are coordinates in the AR coordinate system of the terminal device; and the trajectory point is the location of the terminal device in a roaming test in a detection area;

[0008] Based on the AR coordinates of the trajectory points, a movement trajectory of the terminal device is generated, and the movement trajectory and the detection data are displayed.

[0009] In the above scheme, during the roaming test, not only the detection data corresponding to the track point (the location of the terminal device) is obtained in real time, but also the AR coordinates of the track point in the AR coordinate system are obtained in real time through AR positioning, that is, the detection data of each track point and the corresponding AR coordinates (position information) are obtained in real time during the roaming test. In this way, after the roaming test is completed, the deployment of the AP can be evaluated more accurately based on the detection data of the track point and the corresponding AR coordinates; in addition, the movement trajectory of the terminal device is generated based on the AR coordinates of the track point (which will be updated in real time as the terminal device moves); by displaying the movement trajectory, detection data and the real-life picture corresponding to the detection area, the user can obtain the corresponding detection results of the track points that have been detected based on the movement trajectory and detection data, and plan the subsequent detection routes more reasonably based on this information, and conduct roaming tests more effectively.

[0010] In some optional implementation manners, before generating the movement trajectory of the terminal device, the method further includes:

[0011] In response to the floor plan of the detection area, determine the image coordinates and the first AR coordinates of the first positioning point in the detection area; wherein the first positioning point includes at least two positioning points; the image coordinates are coordinates in the image coordinate system of the floor plan; and the first AR coordinates are coordinates in the initial AR coordinate system of the terminal device;

[0012] Determining a first adjustment ratio between the image coordinate system and the initial AR coordinate system based on the image coordinates of the first positioning point and the first AR coordinates;

[0013] Generating a movement trajectory of the terminal device based on the AR coordinates of the trajectory point includes:

[0014] If the AR coordinate system corresponding to the terminal device is not offset, converting the first AR coordinate of the track point into the image coordinate of the track point based on the first adjustment ratio;

[0015] Based on the image coordinates of the trajectory points, a movement trajectory of the terminal device is generated in the floor plan.

[0016] In the above scheme, the AR coordinate system is used for terminal device positioning; the floor plan is an image, and the image coordinate system is used; at least two first positioning points are used, and the image coordinates and the first AR coordinates of the first positioning points are determined; then the first adjustment ratio between the image coordinate system and the initial AR coordinate system is determined, and the first AR coordinates of the trajectory point are transformed based on the first adjustment ratio to obtain the coordinates in the image coordinate system of the floor plan, and then the moving trajectory is generated in the floor plan. The floor plan has the indoor distribution structure of the detection area, which can more effectively guide the user to plan subsequent detection routes.

[0017] Some optional implementations also include:

[0018] If the AR coordinate system corresponding to the terminal device is offset, determine the image coordinates and the second AR coordinates of the second positioning point; wherein the second positioning point includes at least two positioning points; and the second AR coordinates are coordinates in the offset AR coordinate system of the terminal device;

[0019] determining a second adjustment ratio between the image coordinate system and the offset AR coordinate system based on the image coordinates and the second AR coordinates of the second positioning point;

[0020] Generating a movement trajectory of the terminal device based on the AR coordinates of the trajectory point also includes:

[0021] If the AR coordinate system corresponding to the terminal device is offset, converting the second AR coordinates of the offset trajectory point into the image coordinates of the offset trajectory point based on the second adjustment ratio;

[0022] Based on the image coordinates of the trajectory points after the shift, a moving trajectory of the terminal device after the shift is generated in the floor plan.

[0023] In the above scheme, after the AR coordinate system corresponding to the terminal device is offset, the conversion relationship between the AR coordinate system and the image coordinate system will also change, and the previous first adjustment ratio will no longer apply; after the offset, at least two second positioning points are used, and the image coordinates of the second positioning points and the second AR coordinates (the coordinates in the offset AR coordinate system) are determined; then the second adjustment ratio between the image coordinate system and the offset AR coordinate system is determined, and the second AR coordinates of the offset trajectory points are converted based on the second adjustment ratio, so that the coordinates in the image coordinate system of the floor plan can be obtained, and then the moving trajectory can be generated in the floor plan, so that the moving trajectory can be accurately generated in the AR offset scene.

[0024] In some optional implementation manners, if the AR coordinate system corresponding to the terminal device is offset, the method further includes:

[0025] Based on the first adjustment ratio and the second adjustment ratio, converting the second AR coordinate of the offset trajectory point into the first AR coordinate in the initial AR coordinate system;

[0026] After the roaming test is completed, a roaming track corresponding to the roaming test is generated based on the first AR coordinates of all track points.

[0027] In the above scheme, if the AR coordinate system corresponding to the terminal device is offset during the roaming test, the AR coordinates of the trajectory point are not the AR coordinates in the unified AR coordinate system. By converting the second AR coordinates of the offset trajectory point into the first AR coordinates in the initial AR coordinate system, the first AR coordinates of the unified coordinate standard of all trajectory points in the roaming test are obtained, thereby generating the roaming trajectory of the entire roaming test in the unified coordinate system.

[0028] Some optional implementations also include:

[0031] In some optional implementations, displaying the movement trajectory and the detection data further includes:

[0032] The collected real-life image of the detection area is displayed.

[0033] The above solution, by displaying the collected real-life image of the detection area, facilitates the user to plan the route more reasonably based on the real scene ahead, such as avoiding obstacles, going to a specific area, etc.

[0034] Some optional implementations also include:

[0035] If the real scene image includes a target track point, the annotation information corresponding to the target track point is rendered in the real scene image.

[0036] The above scheme performs AR real scene marking by rendering the annotation information corresponding to the target trajectory point in the real scene image, thereby more intuitively displaying the locations that need to be focused on.

[0037] In some optional implementations, the target trajectory point is determined by:

[0038] In response to a user marking instruction, determining the trajectory point corresponding to the user marking instruction as the target trajectory point; wherein the marking type of the target trajectory point is user marking; and / or

[0039] A trajectory point representing AP switching is determined as the target trajectory point; wherein the annotation type of the target trajectory point is roaming.

[0040] Some optional implementations also include:

[0041] If the real scene image includes a target area, the AP information corresponding to the target area is rendered in the real scene image; wherein the target area is the location of the AP to which the terminal device is currently connected.

[0042] The above solution prompts the user the location of the AP by rendering the AP information corresponding to the location of the AP currently connected to the terminal device in the real-life image, thereby further guiding the user to reasonably plan the roaming route.

[0043] Some optional implementations also include:

[0044] Generate a roaming report for the detection area; wherein the roaming report includes part or all of the roaming track, roaming times, signal strength change curve and delay change curve corresponding to the roaming test.

[0045] The above solution generates a roaming report, which can be used to infer where roaming anomalies occur and where network anomalies and fluctuations occur, thereby providing better signal coverage.

[0046] In a second aspect, an embodiment of the present application provides a roaming test device, which is applied to a terminal device, and the device includes:

[0047] An AR positioning module is used to perform AR positioning at a track point of the terminal device to obtain AR coordinates of the track point; wherein the AR coordinates are coordinates in an AR coordinate system of the terminal device; and the track point is a location of the terminal device in a roaming test in a detection area;

[0094] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0095] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0096] The term "and / or" describes the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0097] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two devices. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0098] In this embodiment, the "terminal device" is a device carried by a user for roaming testing, and may be a handheld device such as a mobile phone.

[0099] During implementation, multiple APs need to be deployed in some areas, and after deployment, roaming tests are required to evaluate the deployment of the APs.

[0100] In the related art, a tester carries a mobile phone and moves around a deployment area, interacts with an AP, performs a roaming test, and obtains a roaming test result; and then evaluates whether the deployment of the AP is reasonable based on the roaming test result.

[0101] However, in the above method, testers can only rely on experience to carry mobile phones and move around the deployment area, which may result in detection blind spots. In addition, the above method can only obtain the changes in roaming test data over time, but cannot determine the location corresponding to the roaming test data, making it difficult to accurately evaluate the deployment of APs.

[0102] In some embodiments, the program-controlled test vehicle is controlled to run in a test scenario according to a preset trajectory, so that the program-controlled test vehicle successively establishes wireless connections with multiple roaming test APs in the test scenario through a test wireless network card, thereby determining test data on the preset trajectory.

[0103] However, the control process of the above method is complicated and requires an additional program-controlled test vehicle to implement.

[0104] In view of this, an embodiment of the present application proposes a roaming test method, apparatus, terminal device and storage medium. The method is applied to the terminal device, including: performing AR positioning at the trajectory point of the terminal device to obtain the AR coordinates of the trajectory point; and determining the detection data corresponding to the trajectory point; wherein the AR coordinates are the coordinates in the AR coordinate system of the terminal device; the trajectory point is the position of the terminal device in the roaming test of the detection area; based on the AR coordinates of the trajectory point, generating a movement trajectory of the terminal device; and displaying the movement trajectory and the detection data.

[0105] In the above scheme, during the roaming test, not only the detection data corresponding to the track point (the location of the terminal device) is obtained in real time, but also the AR coordinates of the track point in the AR coordinate system are obtained in real time through AR positioning, that is, the detection data of each track point and the corresponding AR coordinates (position information) are obtained in real time during the roaming test. In this way, after the roaming test is completed, the deployment of the AP can be evaluated more accurately based on the detection data of the track point and the corresponding AR coordinates; in addition, the movement trajectory of the terminal device is generated based on the AR coordinates of the track point (which will be updated in real time as the terminal device moves); by displaying the movement trajectory, detection data and the real-life picture corresponding to the detection area, the user can obtain the corresponding detection results of the track points that have been detected based on the movement trajectory and detection data, and plan the subsequent detection routes more reasonably based on this information, and conduct roaming tests more effectively.

[0106] The following will be combined with the accompanying drawings and specific embodiments to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0107] Figure 1 A flowchart of the first roaming test method provided in the embodiment of the present application is shown as follows: Figure 1 As shown, the following steps are included:

[0108] Step S101: performing AR positioning at the trajectory point of the terminal device to obtain the AR coordinates of the trajectory point; and determining the detection data corresponding to the trajectory point.

[0109] Among them, the AR coordinates are coordinates in the AR coordinate system of the terminal device; the trajectory point is the location of the terminal device in the roaming test in the detection area.

[0110] During implementation, in order to more accurately evaluate the deployment of APs, not only test data but also location information is obtained in real time.

[0111] Since APs are usually deployed indoors to provide wireless networks for indoor areas, roaming tests are usually performed indoors. Based on this, this embodiment uses terminal devices for AR positioning, which is more suitable for indoor positioning.

[0112] By acquiring the detection data of each track point and the corresponding AR coordinates (location information) in real time during the roaming test, the deployment of the AP can be evaluated more accurately based on the detection data of the track point and the corresponding AR coordinates after the roaming test.

[0113] Step S102: Generate a movement trajectory of the terminal device based on the AR coordinates of the trajectory points.

[0114] During the roaming test, if the tester only relies on experience to move the terminal device, there may be a detection blind spot, that is, there may be an area that the terminal device has not passed through, and the track point is far away from the area, which will also affect the test results;

[0115] Based on this, this embodiment also generates the movement trajectory of the terminal device based on the AR coordinates of the trajectory points (which will be updated in real time as the terminal device moves), so that the user can promptly know the trajectory points that have been detected, and can also combine the movement trajectory with the overall layout of the area to be tested to know the undetected areas.

[0116] Step S103: displaying the movement trajectory and the detection data.

[0117] In this embodiment, after determining the current movement trajectory, the movement trajectory and detection data are displayed. Based on the movement trajectory and detection data, the user can obtain the detection results corresponding to the trajectory points that have been detected. Combined with this information, the subsequent detection route can be planned more reasonably and the roaming test can be performed more effectively.

[0118] It is understandable that the terminal device is mobile and new track points are constantly added during the roaming test. Therefore, a mobile track is generated in real time (new track points are added to the previous mobile track), so that the user can know the route traveled in time.

[0119] This embodiment does not specifically limit the detection data, such as one or more of the data including signal strength, currently connected AP, delay, packet loss rate, negotiation rate, roaming related information, etc., which can be determined based on the interaction message between the terminal device and the AP.

[0120] See also Figure 2 As shown, a user interface provided by this embodiment, the upper left of the user interface is a signal strength change curve, and the upper right is the current network parameters; below the signal strength change curve and the current network parameters, roaming related information is displayed; these are all detection data;

[0121] Below the roaming related information on this user interface is the current movement track.

[0122] It is understandable that the above Figure 2 The user interface shown is only an example. In practice, the positions of different detection data may be swapped, or the movement track may be set at the top and the detection data may be displayed at the bottom, etc. This embodiment does not specifically limit this.

[0123] In implementation, the terminal device can rotate the moving track according to the current direction information (its own direction) (the moving track itself does not change), so that the user has a more intuitive experience. For example, if the terminal device turns left, the moving track will also turn left and keep moving forward from the user's perspective. The above direction information is calculated by the current forward vector and rotation angle of the terminal device.

[0124] The present embodiment does not limit the specific implementation method of the moving trajectory. The moving trajectory can use a uniform line; or use different lines according to different signal strengths, such as a green line for a strong signal, a yellow line for a normal signal, and a red line for a poor signal.

[0125] In the above scheme, during the roaming test, not only the detection data corresponding to the track point (the location of the terminal device) is obtained in real time, but also the AR coordinates of the track point in the AR coordinate system are obtained in real time through AR positioning, that is, the detection data of each track point and the corresponding AR coordinates (position information) are obtained in real time during the roaming test. In this way, after the roaming test is completed, the deployment of the AP can be evaluated more accurately based on the detection data of the track point and the corresponding AR coordinates; in addition, the movement trajectory of the terminal device is generated based on the AR coordinates of the track point (which will be updated in real time as the terminal device moves); by displaying the movement trajectory, detection data and the real-life picture corresponding to the detection area, the user can obtain the corresponding detection results of the track points that have been detected based on the movement trajectory and detection data, and plan the subsequent detection routes more reasonably based on this information, and conduct roaming tests more effectively.

[0126] The present application embodiment provides a flow chart of a second roaming test method, such as Figure 3 As shown, the following steps are included:

[0127] Step S301: In response to the floor plan of the detection area, determine the image coordinates and the first AR coordinates of the first positioning point in the detection area.

[0128] Among them, the first positioning point includes at least two positioning points; the image coordinates are coordinates in the image coordinate system of the floor plan; and the first AR coordinates are coordinates in the initial AR coordinate system of the terminal device.

[0129] In implementation, a floor plan of the detection area can be uploaded to the terminal device, or multiple floor plans can be pre-configured in the terminal device for the user to choose. The floor plan has the indoor distribution structure of the detection area. Therefore, generating a moving trajectory in the floor plan can more effectively guide the user to plan the subsequent detection route;

[0130] However, the AR coordinate system used for terminal device positioning, if the AR coordinate system corresponding to the terminal device has not shifted, uses the initial AR coordinate system; the floor plan is an image, and the image coordinate system is used; only by determining the image coordinates of the trajectory point in the image coordinate system can the movement trajectory be generated in the floor plan;

[0131] Based on this, this embodiment adopts at least two first positioning points, and determines the image coordinates and the first AR coordinates of the first positioning points; then determines the adjustment ratio between the image coordinate system and the initial AR coordinate system, and coordinate transformation can be performed based on the adjustment ratio.

[0132] Step S302: determining a first adjustment ratio between the image coordinate system and the initial AR coordinate system based on the image coordinates of the first positioning point and the first AR coordinates.

[0133] As described above, by determining the image coordinates of the first positioning point and the first AR coordinates, and then determining the adjustment ratio between the image coordinate system and the initial AR coordinate system, coordinate transformation can be performed based on the adjustment ratio.

[0134] Exemplarily, the first adjustment ratio may include a first horizontal adjustment ratio and a first vertical adjustment ratio; the first horizontal adjustment ratio is determined based on the difference between the image horizontal coordinates of different first positioning points and the difference between the first AR horizontal coordinates; the first vertical adjustment ratio is determined based on the difference between the image vertical coordinates of different first positioning points and the difference between the first AR vertical coordinates.

[0135] The following is a specific example to illustrate:

[0136] The coordinates of the first positioning point 11 in the image coordinate system are (a_11, b_11), and the coordinates in the initial AR coordinate system are (X_11, Y_11); the coordinates of the second positioning point 12 in the image coordinate system are (a_12, b_12), and the coordinates in the initial AR coordinate system are (X_12, Y_12);

[0137] The first transverse adjustment ratio K_x=(a_12-a_11) / (X_12-X_11); the first longitudinal adjustment ratio K_y=(b_12-b_11) / (Y_12-Y_11).

[0138] The above example is illustrated using two first positioning points as an example. In implementation, more first positioning points may be used, such as the first horizontal adjustment ratio and the first vertical adjustment ratio are determined based on different first positioning points; or the first horizontal adjustment ratio and the first vertical adjustment ratio corresponding to every two first positioning points may be determined, and the final first horizontal adjustment ratio and the first vertical adjustment ratio may be obtained by combining them, such as calculating the average value of the first horizontal adjustment ratios corresponding to every two first positioning points to obtain the final first horizontal adjustment ratio, and averaging the first vertical adjustment ratios corresponding to every two first positioning points to obtain the final first vertical adjustment ratio, etc.

[0139] Step S303: performing AR positioning at the trajectory point of the terminal device to obtain a first AR coordinate of the trajectory point; and determining detection data corresponding to the trajectory point.

[0140] The specific implementation of step S303 can refer to the above embodiment and will not be described again here.

[0141] Step S304: based on the first adjustment ratio, converting the first AR coordinates of the trajectory point into the image coordinates of the trajectory point.

[0142] Since the first adjustment ratio represents the conversion relationship between the AR coordinate system and the image coordinate system, the first AR coordinates of the trajectory point can be converted into the image coordinates of the trajectory point in the above-mentioned floor plan based on the first adjustment ratio.

[0143] Exemplarily, the first adjustment ratio may include a first transverse adjustment ratio and a first longitudinal adjustment ratio;

[0144] Determine the first AR horizontal coordinate change amount based on the difference between the first AR horizontal coordinate of the trajectory point and the first AR horizontal coordinate of any first positioning point, and determine the first image horizontal coordinate change amount based on the first AR horizontal coordinate change amount and the first horizontal adjustment ratio; add the first image horizontal coordinate change amount to the image horizontal coordinate of the first positioning point to obtain the image horizontal coordinate of the trajectory point;

[0145] Based on the difference between the first AR vertical coordinate of the trajectory point and the first AR vertical coordinate of any first positioning point, the change of the first AR vertical coordinate is determined, and based on the change of the first AR vertical coordinate and the first longitudinal adjustment ratio, the change of the first image vertical coordinate is determined; the image vertical coordinate of the trajectory point can be obtained by adding the first image vertical coordinate change to the image vertical coordinate of the first positioning point.

[0146] For example, the coordinates of the first positioning point 11 in the image coordinate system are (a_11, b_11) and the coordinates in the initial AR coordinate system are (X_11, Y_11):

[0147] The image horizontal coordinate a_m of the track point m=K_x(X_m-X_11)+a_11; wherein K_x is the first horizontal adjustment ratio, X_m is the first AR horizontal coordinate of the track point m, X_11 is the first AR horizontal coordinate of the first positioning point 11, and a_11 is the image horizontal coordinate of the first positioning point 11;

[0148] The image vertical coordinate of the trajectory point m is b_m=K_y(Y_m-Y_11)+b_11; wherein K_y is the first vertical adjustment ratio, Y_m is the first AR vertical coordinate of the trajectory point m, Y_11 is the first AR vertical coordinate of the first positioning point 11, and b_11 is the image vertical coordinate of the first positioning point 11.

[0149] Step S305: generating a moving trajectory of the terminal device in the floor plan based on the image coordinates of the trajectory points.

[0150] Since the image coordinates of the trajectory points are the coordinates in the image coordinate system of the floor plan, the movement trajectory of the terminal device can be generated by drawing points on the floor plan based on the image coordinates of the trajectory points.

[0151] Step S306: Displaying the movement trajectory and the detection data.

[0152] In this embodiment, the movement trajectory is formed in the floor plan, and therefore, displaying the movement trajectory is to display the floor plan including the movement trajectory.

[0153] See also Figure 4 As shown, a user interface provided by this embodiment is provided, and the movement track in the user interface is generated in the floor plan.

[0154] Above Figure 4 The user interface shown is also an exemplary description. The positions of the floor plan and the detection data can be swapped. In addition, the user interface may display the entire floor plan or a portion of the floor plan (for example, when the floor plan is large, only a portion of the floor plan may be displayed). This embodiment does not make specific limitations on this.

[0155] In the above scheme, the AR coordinate system is used for terminal device positioning; the floor plan is an image, and the image coordinate system is used; at least two first positioning points are used, and the image coordinates and the first AR coordinates of the first positioning points are determined; then the first adjustment ratio between the image coordinate system and the initial AR coordinate system is determined, and the first AR coordinates of the trajectory point are transformed based on the first adjustment ratio to obtain the coordinates in the image coordinate system of the floor plan, and then the moving trajectory is generated in the floor plan. The floor plan has the indoor distribution structure of the detection area, which can more effectively guide the user to plan subsequent detection routes.

[0156] The present application embodiment provides a flow chart of a third roaming test method, such as Figure 5 As shown, the following steps are included:

[0157] Step S501: If the AR coordinate system corresponding to the terminal device is offset, the image coordinates of the second positioning point and the second AR coordinates are determined.

[0158] The second positioning points include at least two positioning points; and the second AR coordinates are coordinates in the offset AR coordinate system of the terminal device.

[0159] During implementation, if the AR coordinate system corresponding to the terminal device is offset, the conversion relationship between the AR coordinate system and the image coordinate system will also change;

[0160] Based on this, this embodiment adopts at least two second positioning points, and determines the image coordinates and second AR coordinates of the second positioning points; then determines the adjustment ratio between the image coordinate system and the offset AR coordinate system, and coordinate transformation can be performed based on the adjustment ratio.

[0161] This embodiment does not specifically limit the manner in which the terminal device determines that the AR coordinate system is offset. For example:

[0162] 1. The terminal device will collect images during the AR positioning process. If the images collected by the terminal device do not have relevant feature points, it is determined that the AR coordinate system is offset;

[0163] 2. When the user's current position in the perceived movement trajectory does not match the actual position, a command representing the offset is triggered, and the terminal device responds to the command to determine that the AR coordinate system is offset.

[0164] Step S502: determining a second adjustment ratio between the image coordinate system and the offset AR coordinate system based on the image coordinates of the second positioning point and the second AR coordinates.

[0165] As described above, by determining the image coordinates and the second AR coordinates of the second positioning point, and then determining the adjustment ratio between the image coordinate system and the offset AR coordinate system, the coordinates of the offset trajectory point can be transformed based on the adjustment ratio.

[0166] Exemplarily, the second adjustment ratio may include a second horizontal adjustment ratio and a second vertical adjustment ratio; the second horizontal adjustment ratio is determined based on the difference between the image horizontal coordinates of different second positioning points and the difference between the second AR horizontal coordinates; the second vertical adjustment ratio is determined based on the difference between the image vertical coordinates of different second positioning points and the difference between the second AR vertical coordinates. The method of determining the first adjustment ratio is similar to that described above and will not be repeated here.

[0167] Step S503: performing AR positioning at the trajectory point of the terminal device to obtain a second AR coordinate of the trajectory point; and determining detection data corresponding to the trajectory point.

[0168] The specific implementation of step S503 can refer to the above embodiment and will not be described again here.

[0169] Step S504: based on the second adjustment ratio, converting the second AR coordinates of the offset trajectory point into the image coordinates of the offset trajectory point.

[0170] Since the second adjustment ratio represents the conversion relationship between the offset AR coordinate system and the image coordinate system, the second AR coordinates of the offset trajectory point can be converted into the image coordinates in the above-mentioned floor plan based on the second adjustment ratio.

[0171] Exemplarily, the second adjustment ratio may include a second horizontal adjustment ratio and a second vertical adjustment ratio; based on the difference between the second AR horizontal coordinate of the trajectory point and the second AR horizontal coordinate of any second positioning point, the second AR horizontal coordinate change amount is determined; based on the second AR horizontal coordinate change amount and the second horizontal adjustment ratio, the second image horizontal coordinate change amount is determined; the image horizontal coordinate of the trajectory point can be obtained by adding the second image horizontal coordinate change amount to the image horizontal coordinate of the second positioning point;

[0172] Based on the difference between the second AR vertical coordinate of the trajectory point and the second AR vertical coordinate of any second positioning point, the change of the second AR vertical coordinate is determined, and based on the change of the second AR vertical coordinate and the second longitudinal adjustment ratio, the change of the second image vertical coordinate is determined; the image vertical coordinate of the trajectory point can be obtained by adding the second image vertical coordinate change to the image vertical coordinate of the second positioning point.

[0173] For example, the coordinates of the second positioning point 21 in the image coordinate system are (a_21, b_21), and the coordinates in the offset AR coordinate system are (X_21, Y_21):

[0174] The image horizontal coordinate a_n of the track point n=K′_x(X′_n-X_21)+a_21; wherein K′_x is the second horizontal adjustment ratio, X′_n is the second AR horizontal coordinate of the track point n, X_21 is the first AR horizontal coordinate of the second positioning point 21, and a_21 is the image horizontal coordinate of the second positioning point 21;

[0175] The image ordinate of trajectory point n is b_n=K′_y(Y′_n-Y_21)+b_21; wherein K′_y is the second longitudinal adjustment ratio, Y′_n is the second AR ordinate of trajectory point n, Y_21 is the first AR ordinate of the second positioning point 21, and b_21 is the image ordinate of the second positioning point 21.

[0176] Step S505: Based on the image coordinates of the trajectory points after the shift, a moving trajectory of the terminal device after the shift is generated in the floor plan.

[0177] Since the image coordinates of the trajectory points are the coordinates in the image coordinate system of the floor plan, the movement trajectory of the terminal device can be generated by drawing points on the floor plan based on the image coordinates of the trajectory points.

[0178] As described above, the terminal device is moving, and new trajectory points are constantly added during the roaming test, generating a mobile trajectory in real time (adding new trajectory points to the previous mobile trajectory). Therefore, this embodiment also has a mobile trajectory generation process and display process before the offset. For details, please refer to the above embodiment, which will not be repeated here.

[0179] Step S506: Displaying the movement trajectory and the detection data.

[0180] The specific implementation of step S506 can refer to the above embodiment and will not be described again here.

[0181] In the above scheme, after the AR coordinate system corresponding to the terminal device is offset, the conversion relationship between the AR coordinate system and the image coordinate system will also change, and the previous first adjustment ratio will no longer apply; after the offset, at least two second positioning points are used, and the image coordinates of the second positioning points and the second AR coordinates (the coordinates in the offset AR coordinate system) are determined; then the second adjustment ratio between the image coordinate system and the offset AR coordinate system is determined, and the second AR coordinates of the offset trajectory points are converted based on the second adjustment ratio, so that the coordinates in the image coordinate system of the floor plan can be obtained, and then the moving trajectory can be generated in the floor plan, so that the moving trajectory can be accurately generated in the AR offset scene.

[0182] In some optional implementations, when the AR coordinate system corresponding to the terminal device is offset, the following steps are further performed:

[0183] Based on the first adjustment ratio and the second adjustment ratio, converting the second AR coordinate of the offset trajectory point into the first AR coordinate in the initial AR coordinate system;

[0184] After the roaming test is completed, a roaming track corresponding to the roaming test is generated based on the first AR coordinates of all track points.

[0185] During implementation, if the AR coordinate system corresponding to the terminal device is offset during the roaming test, the AR coordinates of the trajectory point are not the AR coordinates in the AR coordinate system; the second AR coordinates of the offset trajectory point need to be converted into the first AR coordinates in the initial AR coordinate system to obtain the AR coordinates with unified coordinate standards for all trajectory points during the roaming test.

[0186] For example, for trajectory point n, the image coordinates determined based on the first adjustment ratio and the first AR coordinates are theoretically the same as the image coordinates determined based on the second adjustment ratio and the second AR coordinates. Therefore, the corresponding first AR coordinates can be determined based on the first adjustment ratio, the second adjustment ratio and the second AR coordinates.

[0187] The method for determining the first adjustment ratio and the second adjustment ratio can be referred to in the above embodiment and will not be described in detail here.

[0188] The following is a specific example to illustrate the AR coordinate system transformation:

[0189] a_n=K_x(X_n-X_11)+a_11=K′_x(X′_n-X_21)+a_21;

[0190] b_n=K_y(Y_n-Y_11)+b_11=K′_y(Y_n-Y_21)+b_21;

[0191] From the above two formulas, we can infer that X_n=(X′_n-X_21)K′_x / K_x+(a_21-a_11) / K_x+X_11;

[0192] Y_n=(Y′_n-Y_21)K′_y / K_y+(b_21-b_11) / K_y+Y_11;

[0193] Among them, the coordinates of the first positioning point 11 in the image coordinate system are (a_11, b_11), and the coordinates in the initial AR coordinate system are (X_11, Y_11); the coordinates of the second positioning point 21 in the image coordinate system are (a_21, b_21), and the coordinates in the offset AR coordinate system are (X_21, Y_21); K_x is the first horizontal adjustment ratio, K_y is the first vertical adjustment ratio, K′_x is the second horizontal adjustment ratio, K′_y is the second vertical adjustment ratio, the coordinates of the trajectory point n in the offset AR coordinate system are (X′_n, Y′_n), and the coordinates in the initial AR coordinate system are (X_n, Y_n).

[0194] After the roaming test is completed, a roaming trajectory in a unified coordinate system is generated based on the first AR coordinates of all trajectory points in the initial AR coordinate system.

[0195] It can be understood that the above moving trajectory is a real-time trajectory, and the roaming trajectory is an overall trajectory.

[0196] Since the roaming trajectory is the roaming trajectory of the entire roaming test generated based on the AR coordinates of the unified coordinate standard; therefore, a roaming report can be generated based on the roaming trajectory, and abnormality identification can be performed later based on the roaming report.

[0197] In the above scheme, if the AR coordinate system corresponding to the terminal device is offset during the roaming test, the AR coordinates of the trajectory point are not the AR coordinates in the unified AR coordinate system. By converting the second AR coordinates of the offset trajectory point into the first AR coordinates in the initial AR coordinate system, the first AR coordinates of the unified coordinate standard of all trajectory points in the roaming test are obtained, thereby generating the roaming trajectory of the entire roaming test in the unified coordinate system.

[0198] In some optional implementation manners, the above-mentioned displaying the movement trajectory and the detection data further includes:

[0199] The collected real-life image of the detection area is displayed.

[0200] That is to say, this embodiment not only displays the movement trajectory and detection data, but also displays the real-life image of the detection area collected by the terminal device, such as obtaining a real-life image in front of the terminal device by collecting images through the camera of the terminal device.

[0201] See also Figure 6 As shown, a real scene is displayed below the detection data and above the movement track.

[0202] It is understandable that the above Figure 6The user interface shown is only an example. During implementation, the positions of different detection data may be swapped, and the positions of the detection data, movement trajectory and real-scene image may also be swapped. In addition, these three items of information may not be displayed side by side, such as overlaying the movement trajectory on the real-scene image, occupying part of the area of ​​the real-scene image, etc. This embodiment does not make any specific limitations on this.

[0203] The above solution, by displaying the collected real-life image of the detection area, facilitates the user to plan the route more reasonably based on the real scene ahead, such as avoiding obstacles, going to a specific area, etc.

[0204] In some optional implementations, some trajectory points may be marked to obtain target trajectory points, which may be determined by, but not limited to, the following methods:

[0205] In response to a user marking instruction, determining the trajectory point corresponding to the user marking instruction as the target trajectory point; wherein the marking type of the target trajectory point is user marking; and / or

[0206] A trajectory point representing AP switching is determined as the target trajectory point; wherein the annotation type of the target trajectory point is roaming.

[0207] Exemplarily, if the user wants to mark a specific trajectory point, such as a trajectory point with poor signal, a trajectory point with abnormal signal, etc., a user marking instruction can be triggered, such as clicking the position corresponding to the target trajectory point in the user interface of the terminal device, and entering the marking content; the terminal device determines the trajectory point corresponding to the user marking instruction as the target trajectory point, and the marking type of the target trajectory point is user marking;

[0208] If the terminal device determines that AP switching occurs at a certain trajectory point, the trajectory point is determined as a target trajectory point, and the marking type of the target trajectory point is roaming.

[0209] In some optional implementation manners, the following steps are further performed based on the above embodiments:

[0210] The target track point is marked in the moving track.

[0211] As described above, there are multiple types of target trajectory points, such as target trajectory points marked by users, target trajectory points marked by roaming, and target trajectory points marked with special symbols in the moving trajectory, and corresponding types can also be added.

[0212] See also Figure 7 As shown, the target track point is marked with a dot in the moving track, and the corresponding type is added in the form of a dialog box.

[0213] The above solution records some locations that need to be focused on in the trajectory by marking the target trajectory points in the moving trajectory.

[0214] In some optional implementation manners, the following steps are further performed based on the above embodiments:

[0215] If the real scene image includes a target track point, the annotation information corresponding to the target track point is rendered in the real scene image.

[0216] This embodiment displays a real scene image. If the real scene image contains target track points, annotation information corresponding to the target track points can be rendered in the real scene image to perform AR real scene marking.

[0217] This embodiment does not specifically limit the annotation information. For example, since there are multiple types of target trajectory points, such as target trajectory points marked by users and target trajectory points of roaming, the annotation information may include corresponding types. In addition, for target trajectory points marked by users, the annotation information may also include the marked content. For target trajectory points of roaming, the annotation information may also include roaming-related information, such as the original AP, the AP after switching, switching parameters, etc.

[0218] During implementation, the moving path may also be rendered in the real scene image.

[0219] See also Figure 8 As shown, for the target track point marked by the user, the type of the target track point, the network parameters of the target track point and the marked content are rendered in the real scene. Figure 8 Taking "the signal at the stairwell door is not very good" as an example, during implementation, the user can enter other annotation content.

[0220] See also Fig. 9 As shown, for the target track point of roaming, the type of the target track point is rendered in the real scene, switching from AP1 to AP2, AP1 address, AP2 address and switching parameters, etc. Fig. 9 Take the handover parameters including signal strength change, roaming time and roaming packet loss as an example.

[0221] The above scheme performs AR real scene marking by rendering the annotation information corresponding to the target trajectory point in the real scene image, thereby more intuitively displaying the locations that need to be focused on.

[0222] In some optional implementation manners, based on the above embodiments, the following steps are further performed:

[0223] If the real scene image includes a target area, the AP information corresponding to the target area is rendered in the real scene image; wherein the target area is the location of the AP to which the terminal device is currently connected.

[0224] During implementation, the user may not be clear about the specific location of the AP deployment. Based on this, this embodiment renders the location of the AP to which the terminal device is currently connected in the real scene image.

[0225] See also Fig.10 As shown, the terminal device is currently connected to AP2, and the corresponding AP information is rendered at the location of AP2 in the real scene. Fig.10 Take the example where the AP information includes the AP to which the terminal device is currently connected and the symbol corresponding to the AP.

[0226] The above solution prompts the user the location of the AP by rendering the AP information corresponding to the location of the AP currently connected to the terminal device in the real-life image, thereby further guiding the user to reasonably plan the roaming route.

[0227] In some optional implementation manners, based on the above embodiments, the following steps are further performed:

[0228] generating a roaming report for the detection area;

[0229] The roaming report includes part or all of the roaming track, roaming times, signal strength change curve and delay change curve corresponding to the roaming test.

[0230] The generation method of the roaming trajectory can refer to the above embodiment. The roaming number is the number of switching of the AP connected to the AR during the roaming test. The signal strength change curve is the change of signal strength over time. The delay change curve is the change of delay over time.

[0231] In this embodiment, by generating a roaming report, it is possible to subsequently infer where roaming anomalies occur and where network anomalies and fluctuations occur based on the report, thereby providing better signal coverage.

[0232] like Fig.11 As shown, an embodiment of the present application provides a roaming test device 1100, which is applied to a terminal device, and the device includes:

[0248] Based on the image coordinates of the trajectory points after the shift, a moving trajectory of the terminal device after the shift is generated in the floor plan.

[0264] Generate a roaming report for the detection area; wherein the roaming report includes part or all of the roaming track, roaming times, signal strength change curve and delay change curve corresponding to the roaming test.
