Technical Field

[0003] This application relates to the field of electronic technology, specifically to methods, devices, equipment, storage media, and program products for detecting the ranging scale of ranging devices. Background Technology

[0004] Currently, the main instruments and equipment used for precision distance measurement in engineering construction are satellite positioning terminals and total stations. Long-term engineering construction surveying practice has revealed differences in distance measurement scales among these instruments and equipment. While these differences have a relatively small impact on ordinary measurements, they pose significant challenges to the accuracy and quality of precision distance measurements and cannot be ignored.

[0005] Measuring instruments are typically calibrated by quality supervision and inspection agencies. However, due to the influence of different agencies' established "length benchmark baselines," testing equipment, and testing environments, the technical parameters of precision distance measuring instruments vary. Furthermore, differences in distance measurement exist between different models of instruments. These differences can affect the accuracy and quality of engineering construction measurements. Especially in large-scale engineering projects, multiple surveying teams use instruments of varying models and accuracies. To ensure project quality, it is essential to conduct on-site measurement dimensional testing of all parties' instruments. Therefore, there is an urgent need to apply for a precise measurement dimensional testing method for engineering projects, ensuring consistent accuracy across various precision distance measuring instruments used during construction. Summary of the Invention

[0006] In view of this, this application provides a method, apparatus, equipment, storage medium, and program product for detecting the distance measurement scale of a distance measuring device, in order to solve the problem that precise distance detection cannot be achieved due to deviations in the scale of measuring instruments measured by different quality supervision and inspection agencies, as well as differences in distance measurement between different models of distance measuring instruments.

[0007] In a first aspect, this application provides a method for detecting the distance scale of a distance measuring device. The method includes: using a reference distance measuring device to perform two-phase observations of the distance between a first observation point and at least one second observation point, obtaining first distance information between each second observation point and the first observation point corresponding to each phase of observation; sequentially using different distance measuring devices to be tested to perform two-phase observations of the distance between the first observation point and at least one second observation point, obtaining second distance information between each second observation point and the first observation point obtained by each distance measuring device to be tested in each phase of observation; and calculating... The reference distance information between the second observation point and the first observation point is used; based on the second distance information between the second observation point and the first observation point obtained by each ranging device to be tested in each observation period, the observation distance information between the corresponding second observation point and the first observation point detected by the ranging device to be tested is calculated; based on the observation distance information between the second observation point and the first observation point detected by each ranging device to be tested and the reference distance information between the second observation point and the first observation point, the scale data of the corresponding ranging device to be tested is determined; the ranging device to be tested whose scale data meets the preset requirements among different ranging devices to be tested is determined as the target ranging device.

[0008] The distance measurement scale detection method for distance measuring devices provided in this application utilizes a reference distance measuring device to perform two-stage observations of the distance between each second observation point and a first observation zone point. Based on the results of the two-stage observations, the reference distance information between the corresponding second observation point and the first observation point is determined. Then, different distance measuring devices to be tested are used sequentially to perform two-stage observations of the distance between each second observation point and the first observation point. Based on the results of the two-stage observations, the observation distance information between the corresponding second observation point and the first observation point detected by each distance measuring device to be tested is determined. Finally, based on the observation distance information between each second observation point and the first observation point detected by each distance measuring device to be tested, and the distance between each second observation point and the first observation zone point... The reference distance information between observation points determines the scale data of the corresponding ranging device to be tested; the ranging device whose scale data meets the preset requirements among different ranging devices to be tested is determined as the target ranging device. The target ranging device is the ranging device whose scale meets the requirements, which can ensure the scale consistency between different ranging devices. Different target ranging devices can simultaneously perform distance testing at the construction site, which can realize precise distance measurement during the construction period. This solves the problem in related technologies that the scale of measuring instruments measured by different quality supervision and inspection agencies is biased, and the distance measurement difference of different models of ranging instruments also exists, which makes it impossible to achieve precise distance detection.

[0009] In one optional implementation, the step of determining the ranging device to be tested whose scale data meets the preset requirements as the target ranging device includes: obtaining the scale deviation range of the ranging device to be tested; and determining the ranging device to be tested whose scale data is within the scale deviation range as the target ranging device.

[0015] In an optional implementation, when the ranging device to be tested is a total station, the step of determining the scale detection error of the ranging device to be tested based on the observation distance information between each second observation point and the first observation point and the reference distance information between each second observation point and the first observation point further includes:

[0016] The measurement error of the total station under test is determined based on the observation distance information between each second observation point and the first observation point, the reference distance information between each second observation point and the first observation point, and the second relational formula.

[0017] The second relation is: K S =(K1) S +K2 S ) / 2

[0018] Among them, K S D represents the dimensional data of the total station to be tested. 12 D represents the reference distance information between the first observation point and the first second observation point. 13 D1 represents the reference distance information between the first observation point and the second observation point. 12 This represents the first distance information between the first observation point and the first second observation point in the first phase of observation, D2. 12 This represents the first distance information between the first observation point and the first second observation point corresponding to the second phase of observation, D1. 13 D2 represents the first distance information between the first observation point and the second observation point in the first phase of observation. 13 S represents the first distance information between the first observation point and the second observation point corresponding to the second phase of observation. 12 S represents the observation distance information between the first second observation point and the first observation point. 12 S1 represents the observation distance information between the second observation point and the first observation point.12 This represents the second distance information between the first observation point and the first second observation point in the first phase of observation, S1. 12 This represents the second distance information between the first observation point and the first second observation point corresponding to the second phase of observation, S1. 13 This represents the second distance information between the first observation point and the second observation point in the first phase of observation, S2. 13 This indicates the second distance information between the first observation point and the second second observation point corresponding to the second phase of observation.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] In related technologies, measuring instruments are typically calibrated by quality supervision and inspection agencies. However, due to the influence of different agencies' established "length benchmark baselines," testing equipment, and testing environments, the technical parameters of precision distance measuring instruments vary. Furthermore, distance measurement differences also exist between different models of instruments. These differences can affect the accuracy and quality of engineering construction measurements. Especially in large-scale engineering projects where multiple surveying teams conduct measurements using different models and accuracies of instruments, it is essential to conduct on-site measurement dimensional testing of all measuring instruments used by each team to ensure project quality.

[0032] In view of this, the ranging scale detection method for a ranging device provided in this application embodiment can be applied to a server to realize the ranging scale detection of the ranging device. The method provided in this application embodiment utilizes a reference ranging device to perform two-stage observations of the distance between each second observation point and a first observation zone point, and determines the reference distance information between the corresponding second observation point and the first observation point based on the results of the two-stage observations; sequentially, different ranging devices to be tested are used to perform two-stage observations of the distance between each second observation point and the first observation point, and the observation distance information between the corresponding second observation point and the first observation point detected by each ranging device to be tested is determined based on the observation distance information between each second observation point and the first observation point detected by each ranging device to be tested, and the distance between each second observation point and the first observation point... The reference distance information between them determines the scale data of the corresponding ranging device to be tested; the ranging device whose scale data meets the preset requirements among different ranging devices to be tested is determined as the target ranging device. The target ranging device is the ranging device whose scale meets the requirements, which can ensure the consistency of scale between different ranging devices. Different target ranging devices can simultaneously perform distance testing at the construction site, which can realize precise distance measurement during the construction period. This solves the problem in related technologies that the scale of measuring instruments measured by different quality supervision and inspection agencies is biased, and the distance measurement difference of different models of ranging instruments also exists, which makes it impossible to achieve precise distance detection.

[0033] According to an embodiment of this application, a method for detecting the ranging scale of a ranging device is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0034] This embodiment provides a method for detecting the ranging scale of a ranging device, which can be used in the aforementioned server. Figure 1 is a flowchart of the method for detecting the ranging scale of a ranging device according to an embodiment of this application. As shown in Figure 1, the process includes the following steps:

[0035] Step S101: Use a reference ranging device to perform two-stage observations on the distance between the first observation point and at least one second observation point to obtain the first distance information between each second observation point and the first observation point corresponding to each stage of observation.

[0036] For example, the reference ranging device can be a ranging device with sufficient measurement accuracy, including but not limited to a reference satellite positioning terminal and a total station with sufficient measurement accuracy. In this embodiment, the number of second observation points is two.

[0037] Step S102: The distance between the first observation point and at least one second observation point is observed in two phases using different ranging devices to be tested, so as to obtain the second distance information between each second observation point and the first observation point obtained by each ranging device to be tested in each phase of observation.

[0038] For example, the ranging device to be tested may include different types and models of ranging devices. In the embodiments of this application, the ranging device to be tested may include, but is not limited to, a satellite positioning terminal and a total station.

[0039] Step S103: Calculate the reference distance information between the corresponding second observation point and the first observation point based on the first distance information between each second observation point and the first observation point for each period of observation.

[0040] For example, in this embodiment of the application, the average value of the first distance information between each second observation point and the first observation point obtained from the two observations is processed to obtain the reference distance information between the corresponding second observation point and the first observation point.

[0041] Step S104: Calculate the observation distance information between the corresponding second observation point and the first observation point detected by the corresponding ranging device under test based on the second distance information between each second observation point and the first observation point obtained by each ranging device under test in each observation period.

[0044] For example, in the embodiments of this application, the scale data of the corresponding ranging device to be tested is determined by the observation distance information between each second observation point and the first observation point detected by each ranging device to be tested, as well as the reference distance information between each second observation point and the first observation point. The embodiments of this application do not limit the calculation method, and those skilled in the art can determine it according to their needs, as long as the scale calculation can be achieved.

[0045] Step S106: The ranging device whose scale data meets the preset requirements among different ranging devices to be tested is identified as the target ranging device.

[0046] For example, the preset requirements may include, but are not limited to, the scale deviation range information of the ranging device to be detected. In this embodiment, if there are multiple target ranging devices among different ranging devices to be detected, it is assumed that the scales of the multiple target ranging devices are consistent and can be used simultaneously.

[0047] The ranging scale detection method for the ranging device provided in this embodiment utilizes a reference ranging device to perform two-stage observations of the distance between each second observation point and the first observation point. Based on the results of the two-stage observations, the reference distance information between the corresponding second observation point and the first observation point is determined. Then, different ranging devices to be tested are used sequentially to perform two-stage observations of the distance between each second observation point and the first observation point. Based on the results of the two-stage observations, the observation distance information between the corresponding second observation point and the first observation point detected by each ranging device to be tested is determined. Finally, based on the observation distance information between each second observation point and the first observation point detected by each ranging device to be tested, and the distance between each second observation point and the first observation point... The reference distance information between observation points determines the scale data of the corresponding ranging device to be tested; the ranging device whose scale data meets the preset requirements among different ranging devices to be tested is determined as the target ranging device. The target ranging device is the ranging device whose scale meets the requirements, which can ensure the scale consistency between different ranging devices. Different target ranging devices can simultaneously perform distance testing at the construction site, which can realize precise distance measurement during the construction period. This solves the problem in related technologies that the scale of measuring instruments measured by different quality supervision and inspection agencies is biased, and the distance measurement difference of different models of ranging instruments also exists, which makes it impossible to achieve precise distance detection.

[0048] This embodiment provides a method for detecting the ranging scale of a ranging device, which can be used in the aforementioned server. Figure 2 is a flowchart of the method for detecting the ranging scale of a ranging device according to an embodiment of this application. As shown in Figure 2, the process includes the following steps:

[0049] Step S201 involves using a reference ranging device to perform two-stage observations of the distance between the first observation point and at least one second observation point, obtaining first distance information between each second observation point and the first observation point for each stage of observation. For details, please refer to step S101 of the embodiment shown in Figure 1, which will not be repeated here.

[0050] Step S202 involves sequentially using different ranging devices to be tested to observe the distance between the first observation point and at least one second observation point in two phases, obtaining the second distance information between each second observation point and the first observation point obtained by each ranging device in each phase of observation. For details, please refer to step S102 of the embodiment shown in Figure 1, which will not be repeated here.

[0051] Step S203: Calculate the reference distance information between the corresponding second observation point and the first observation point based on the first distance information between each second observation point and the first observation point in each observation period. For details, please refer to step S103 of the embodiment shown in Figure 1, which will not be repeated here.

[0052] Step S204: Calculate the observation distance information between the corresponding second observation point and the first observation point detected by the corresponding ranging device under test based on the second distance information between each second observation point and the first observation point obtained by each ranging device under test in each observation period.

[0053] Step S205: Determine the scale data of the corresponding ranging device to be tested based on the observation distance information between each second observation point and the first observation point detected by each ranging device to be tested, as well as the reference distance information between each second observation point and the first observation point.

[0054] Specifically, the number of second observation points is two. When the ranging device to be detected is a satellite positioning terminal to be detected, the above step S205 includes:

[0055] Step S2051: Determine the scale data of the satellite positioning terminal under test based on the observation distance information between the second observation point and the first observation point detected by the satellite positioning terminal under test, the reference distance information between each second observation point and the first observation point, and the first relational formula.

[0056] The first relation is shown in equations (1), (2), and (3): K D =(K1) D +K2 D ) / twenty one)

[0057] Among them, K D D represents the scale data of the satellite positioning terminal to be tested. 12 D represents the reference distance information between the first observation point and the first second observation point.13 D1 represents the reference distance information between the first observation point and the second observation point. 12 This represents the first distance information between the first observation point and the first second observation point in the first phase of observation, D2. 12 This represents the first distance information between the first observation point and the first second observation point corresponding to the second phase of observation, d. 12 This represents the observation distance information between the first second observation point and the first observation point, d. 13 This represents the observation distance information between the second observation point and the first observation point, d1. 12 This represents the second distance information between the first observation point and the first second observation point in the first phase of observation, d2. 12 This represents the second distance information between the first observation point and the first second observation point in the second phase of observation, d1. 13 This represents the second distance information between the first observation point and the second observation point in the first phase of observation, d2. 13 This indicates the second distance information between the first observation point and the second second observation point corresponding to the second phase of observation.

[0058] For example, in this embodiment of the application, when the ranging device to be detected includes the satellite positioning terminal to be detected, there are 3 reference ranging devices. The reference ranging devices are reference satellite positioning terminals. It is assumed that there are three high-precision reference satellite positioning terminals numbered D1 to D3 (parameters are A+B×D, where A is the fixed error, B is the proportional error ≤0.5mm / km, and D is the baseline length in km). Three observation piers TP01, TP02, and TP03 are selected (the distance from TP01 to TP02 and TP03 is greater than 1km respectively). Observation pier TP01 is set at the position of the first observation point, observation pier TP02 is set at the position of one observation point, and observation pier TP03 is set at the position of another observation pier. The position diagram of the three observation piers can be shown in Figure 3. During distance observation, three reference satellite terminals, numbered D1 to D3, were first erected on three observation piers, leveled, and their heights measured. The terminals were then powered on, and devices with electromagnetic emission sources, such as walkie-talkies, were moved approximately 20 meters away from the observation piers. After observation for t (t≥2) hours, the terminals were powered off, concluding the first period of the first phase of observation. The distance information between different second observation points and the first observation point was recorded as D11. 12 D11 13 Among them, D11 12 D11 represents the distance between observation pier TP01 and observation pier TP02. 13 This represents the distance between observation piers TP01 and TP03. After rotating the three satellite positioning terminals 180° and slightly leveling them, they were powered on and observed for t hours before being powered off. The second observation period ended. The distances between different second observation points and the first observation point were represented as D12.12 D12 13 The first phase of observation has ended. Following the methods and procedures of the first phase, observations were conducted sequentially on three reference satellite positioning terminals numbered D1 to D3. The distance information between different second observation points and the first observation point was recorded as D21. 12 D21 13 D22 12 D22 13 The second phase of observation has ended.

[0059] The first phase of observation corresponds to the first distance information D1 between the first observation point and the first second observation point. 12 Determined by the following formula (4): D1 12 =(D11) 12 +D12 12 ) / twenty four)

[0060] The second phase of observation corresponds to the first distance information D2 between the first observation point and the first second observation point. 12 Determined by the following formula (5): D2 12 =(D21) 12 +D22 12 ) / 2 (5)

[0062] The second phase of observation corresponds to the first distance information D2 between the first observation point and the second second observation point. 13 D2 is determined by the following formula (7): 13 =(D21) 13 +D22 13 ) / 2 (7)

[0063] The observation distance information between the second observation point and the first observation point detected by the satellite positioning terminal under test is determined in the following way:

[0064] Three satellite positioning terminals, numbered d1 to d3 (with parameters a + b × d, where a is the fixed error, b is the proportional error in mm / km, and d is the baseline length in km), were mounted on three observation piers, leveled, and their heights measured. The terminals were then powered on, and devices with electromagnetic emission sources, such as walkie-talkies, were moved approximately 20 meters away from the observation piers. After observation for t (t ≥ 2 hours), the terminals were powered off. The baseline lengths observed were d11 and d3 respectively. 12d11 13 , among which, d11 12 d11 represents the distance between observation pier TP01 and observation pier TP02. 13 This indicates the distance between observation piers TP01 and TP03. After rotating the three satellite positioning terminals to be tested 180° and slightly leveling them, they were powered on and observed for t hours before being powered off. The second observation period ended, and the observation baseline lengths were d12... 12 d12 13 Similarly, d11 12 d11 represents the distance between observation pier TP01 and observation pier TP02. 13 This indicates the distance between observation piers TP01 and TP03, marking the end of the first phase of observation. Following the methods and procedures of the first phase, observations were subsequently conducted sequentially on the three satellite positioning terminals numbered d1 to d3, with baseline lengths of d21... 12 d21 13 d22 12 d22 13 The second phase of observation has ended.

[0065] The first phase of observation corresponds to the first distance information d1 between the first observation point and the first second observation point. 12 d1 is obtained by calculating using the following formula (8): 12 =(d11) 12 +d12 12 ) / 2 (8)

[0066] The second phase of observation corresponds to the first distance information d2 between the first observation point and the first second observation point. 12 d2 is obtained by calculation using the following formula (9): 12 =(d21) 12 +d22 12 ) / 2 (9)

[0067] The first phase of observation corresponds to the first distance information d1 between the first observation point and the second observation point. 13 d1 is obtained by calculation using the following formula (10): 13 =(d11) 13 +d12 13 ) / 2 (10)

[0068] The second phase of observation corresponds to the first distance information d2 between the first observation point and the first second observation point. 13 d2 is calculated using the following formula (11). 13 =(d21) 13 +d22 13 ) / 2 (11)

[0069] In some optional implementations, when the ranging device to be tested is a total station, step S205 further includes:

[0073] For example, in this embodiment of the application, the observation distance information between each second observation point detected by the total station to be tested and the first observation point is determined in the following manner:

[0074] The total station to be tested (parameters are a"+b"×s, where a" is the fixed error, b" is the proportional error, in mm / km, and s is the test baseline length, in km) must undergo precise testing using both "additional constant" and "prism constant difference". The total station to be tested is set up on point TP01, leveled, and its height is measured. Two prisms with approximately equal constant differences (constant difference ≤ 0.1mm; prisms with a constant difference greater than 0.1mm can be used for constant difference correction of the measured distance) are selected and set up on observation piers TP02 and TP03 respectively, leveled, and their heights measured. The prism faces are aligned with the direction of the total station to be tested. Meteorological parameters at both ends of the baseline are recorded, and station information is input into the instrument. The observation distances are measured according to the prescribed number of repetitions, with distances of S11. 12 S11 13 S11 12 S11 represents the distance between observation pier TP01 and observation pier TP02. 13 This indicates the distance between observation piers TP01 and TP03; after rotating the prism base 180° and slightly leveling it, record the meteorological parameters and input them into the instrument. Observe the distances S12 according to the prescribed number of measurements. 12 S12 13 Similarly, S12 12 S12 represents the distance between observation pier TP01 and observation pier TP02. 13 This indicates the distance between observation piers TP01 and TP03. Observations were performed sequentially according to the observation steps of the first expected total station test, with the observation distances being S21. 12 S21 13 S22 12 S22 13 The second phase of observations has concluded.

[0075] The first phase of observation corresponds to the first distance information S1 between the first observation point and the first second observation point. 12 S1 is obtained by calculation using the following formula (15): 12 =(S11) 12 +S12 12 ) / 2 (15)

[0076] The second phase of observation corresponds to the first distance information S2 between the first observation point and the first second observation point. 12 S2 is obtained by calculation using the following formula (16): 12 =(S21) 12 +S22 12 ) / 2 (16)

[0077] The first phase of observation corresponds to the first distance information S1 between the first observation point and the second observation point. 13S1 is obtained by calculation using the following formula (17): 13 =(S11) 13 +S12 13 ) / 2 (17)

[0078] The second phase of observation corresponds to the first distance information S2 between the first observation point and the first second observation point. 13 S2 is calculated using the following formula (18). 13 =(S21) 13 +S22 13 ) / 2 (18)

[0079] Step S206: The ranging device whose scale data meets the preset requirements among different ranging devices to be tested is determined as the target ranging device. For details, please refer to step S106 of the embodiment shown in Figure 1, which will not be repeated here.

[0080] This embodiment provides a method for detecting the ranging scale of a ranging device, which can be used in the aforementioned server. Figure 4 is a flowchart of the method for detecting the ranging scale of a ranging device according to an embodiment of this application. As shown in Figure 4, the process includes the following steps:

[0081] Step S401 involves using a reference ranging device to perform two-stage observations of the distance between the first observation point and at least one second observation point, obtaining first distance information between each second observation point and the first observation point for each stage of observation. For details, please refer to step S201 of the embodiment shown in Figure 1, which will not be repeated here.

[0082] Step S402 involves sequentially using different ranging devices to be tested to observe the distance between the first observation point and at least one second observation point in two phases, obtaining the second distance information between each second observation point and the first observation point obtained by each ranging device in each phase of observation. For details, please refer to step S202 of the embodiment shown in Figure 1, which will not be repeated here.

[0083] Step S403: Calculate the reference distance information between the corresponding second observation point and the first observation point based on the first distance information between each second observation point and the first observation point in each observation period. For details, please refer to step S203 of the embodiment shown in Figure 1, which will not be repeated here.

[0084] Step S404: Based on the second distance information between each second observation point and the first observation point obtained by each ranging device to be detected in each observation period, calculate the observation distance information between the corresponding second observation point and the first observation point detected by the ranging device to be detected. For details, please refer to step S204 of the embodiment shown in Figure 1, which will not be repeated here.

[0085] Step S405: Based on the observation distance information between each second observation point and the first observation point detected by each ranging device to be tested, and the reference distance information between each second observation point and the first observation point, determine the scale data of the corresponding ranging device to be tested. For details, please refer to step S205 of the embodiment shown in Figure 1, which will not be repeated here.

[0086] Step S406: The ranging device whose scale data meets the preset requirements among different ranging devices to be tested is identified as the target ranging device.

[0087] Specifically, step S406 includes:

[0088] Step S4061: Obtain the scale deviation range of the ranging device to be tested.

[0089] For example, in this embodiment of the application, the scale deviation of the satellite positioning terminal to be detected ranges from 0 to 2 × 10⁻⁶. -6 .

[0090] Step S4062: The ranging devices whose scale data are within the scale deviation range among the different ranging devices to be tested are identified as the target ranging devices.

[0091] For example, in the embodiments of this application, if |1-K d |、|1-K S |All ≤2×10 -6 If the measurement scales of the satellite terminals and total stations in this group are consistent, they can be used simultaneously; otherwise, they cannot be used simultaneously. If |1-K d |、|1-K S |Only one of the instruments has a ≤2×10 -6 or both are greater than 2×10 -6 If the two instruments have different scales, they cannot be used simultaneously.

[0092] In some alternative implementations, the method further includes:

[0093] Step a1: Obtain the detection error threshold for each ranging device to be tested.

[0094] For example, in this embodiment of the application, the detection error threshold of the satellite positioning terminal to be tested is 0.3 + b × d (0.3 is the "residual error (empirical value)" after eliminating fixed errors, b is the proportional error of the satellite terminal measured by the detection baseline, and d is the detection baseline length), and the detection error threshold of the total station to be tested is a" + b" × s (a" is an additive constant, b" is a multiplicative constant, in mm / km, and s is the detection baseline length, in km).

[0095] Step a2: Based on the second distance information between each second observation point and the first observation point obtained by each ranging device to be tested in each observation period, calculate the distance detection error of the corresponding ranging device to be tested.

[0096] For example, in this embodiment of the application, the detection error σ of the satellite positioning terminal to be detected d The following formula (19) is used to calculate:

[0097] The detection error σ of the total station to be tested s The following formula (20) is used to calculate:

[0098] Step a3: If the distance detection error of any distance measuring device to be tested is less than or equal to the detection error threshold of the corresponding distance measuring device to be tested, then the detection error of the distance measuring device to be tested is determined to meet the requirements.

[0099] For example, in this embodiment of the application, if the detection error of the satellite positioning terminal to be tested meets the requirements, then the satellite positioning terminal to be tested is qualified; otherwise, it is unqualified. If the detection error of the total station to be tested meets the requirements, then the total station to be tested is qualified; otherwise, it is unqualified.
