Description

Technical Field

[0001] This application belongs to the technical field of deformation measurement, and particularly relates to a large-range structural deformation monitoring method and related devices. Background Art

[0002] At present, on the one hand, the measurement methods for large structures have problems of long measurement period and poor measurement accuracy. Specifically, traditional optical measurement technologies use instruments such as level gauges, optical theodolites, and electronic total stations to measure civil structures. It is difficult to automate the measurement process, the measurement period is relatively long, and the measurement results are also easily affected by atmospheric jitter, which affects the measurement accuracy. At the same time, it is also affected by the instability of the measurement platform itself, thus affecting the measurement accuracy.

[0003] On the other hand, there are also problems of limited measurement range and cost. For the measurement method of a single-camera optoelectronic deflection meter, a single camera is difficult to handle the measurement task of large structures. The distribution of measurement points to be measured on large structures is often relatively sparse, and the interval between measurement points to be measured reaches dozens of meters, resulting in inconsistent image resolutions of the images of different measurement points to be measured captured by a single camera, thereby affecting the measurement accuracy. For the array camera measurement scheme, that is, multiple cameras form an array camera. Although it can extend the measurement range and improve the measurement accuracy to a certain extent, the array cameras establish connections with each other through the method of image field stitching. The sparse distribution characteristic of the measurement points to be measured on large structures leads to the need to consume a large number of cameras for stitching coverage, resulting in a high cost.

[0043] Please refer to Figure 1A , Figure 1A which is a schematic diagram of the architecture of a large-scale structural deformation monitoring system provided by the embodiments of the present application. As Figure 1A shown, the large-scale structural deformation monitoring system 1 includes a terminal device 10, a processing device 20, an observation platform 30, a camera unit 40, and a total station 50.

[0044] Among them, the terminal device 10 is connected to the processing device 20, and the processing device 20 is respectively connected to the camera unit 40 and the total station 50.

[0045] Among them, the observation platform 30, that is, the camera platform, may be a platform for setting up a camera, or a pier, or a tripod, etc., which is not limited herein.

[0046] Among them, the civil structures include bridges, tunnels, high-rise buildings, dams, roadbeds, and so on.

[0047] Please refer to Figure 1B , Figure 1B which is a schematic diagram of a scenario measured by a camera unit provided in an embodiment of the present application. The large-scale structural deformation monitoring system 1 further includes a reference point 60 and a measurement point 70 to be measured. The camera unit 40 includes a measurement camera and a calibration camera 42.

[0048] Among them, the measurement camera 41 is used to capture an image of the measurement point 70 to be measured, and the calibration camera is used to capture an image of the reference point 60. The measurement point 70 to be measured is a point to be measured marked on the target large-scale structure to be measured. The horizontal distances of different measurement points 70 to be measured on the target large-scale structure to be measured in the camera coordinate system are different, and the vertical distances of different measurement points 70 to be measured are the same or the vertical distances of different measurement points 70 to be measured are within a preset distance interval.

The number and position settings of the measurement points 70 to be measured can be set according to the structural form and actual needs of the civil structure.

[0049] Among them, the camera parameters of each camera in the camera unit 40 can be set according to actual needs.

[0050] In a possible example, the terminal device 10 first responds to a first selection operation of the user for the large-scale structure to be measured measurement control in the measurement management interface of the structure to be measured, and displays a large-scale structure to be measured type selection interface.

[0051] Please refer to Figure 2 , Figure 2 which is a schematic flowchart of a large - scale structure deformation monitoring method provided by an embodiment of the present application, and is applied to a terminal device in a structure deformation monitoring system. The structure deformation monitoring system includes the terminal device, a processing device, an observation platform, and a camera unit arranged on the observation platform. The terminal device is connected to the processing device, and the processing device is connected to the camera unit. The method includes:

[0052] Step S201: In response to a first selection operation of a user on a large - scale structure to be measured control in a structure to be measured measurement management interface, display a large - scale structure type to be measured selection interface, where the large - scale structure type to be measured selection interface includes a plurality of structure type controls.

[0053] Among them, please refer to Figure 3 , Figure 3 which is a schematic diagram of a structure to be measured measurement management interface provided by an embodiment of the present application. As shown in Figure 3 , the terminal device displays a structure to be measured measurement management interface 300. The structure to be measured measurement management interface 300 includes a large - scale structure to be measured control 301, a large - depth structure to be measured control 302, and other structure to be measured controls 303. The large - scale structure to be measured control 301 is used to obtain the first selection operation of the user.

[0054] Among them, the first selection operation is used to indicate the start of large - scale structure to be measured measurement configuration. The first selection operation can specifically be a click operation or a touch operation on the large - scale structure to be measured control 301. After the user clicks the large - scale structure to be measured control 301, the terminal device displays a large - scale structure type to be measured selection interface for the user to select the structure type of the structure to be measured.

[0055] Step S202: In response to a second selection operation of the user on a target structure type control in the large - scale structure type to be measured selection interface, display the target large - scale structure to be measured measurement interface, where the target large - scale structure to be measured measurement interface includes a target large - scale structure to be measured input data area and a start measurement control.

[0056] Among them, the structure types include bridges, tunnels, high - rise buildings, dams, and roadbeds, etc.

[0057] Please refer to Figure 4 , Figure 4 which is a schematic diagram of a large - scale structure type to be measured selection interface provided by an embodiment of the present application. The large - scale structure type to be measured selection interface 400 includes a bridge measurement control 401, a tunnel measurement control 402, a high - rise building measurement control 403, a dam measurement control 404, a roadbed measurement control 405, and other measurement controls 406.

[0058] Among them, the second selection operation is used to indicate the selection of the structure type. The second selection operation can specifically be a click operation or a touch operation on any one of the bridge measurement control 401, tunnel measurement control 402, high-rise building measurement control 403, dam measurement control 404, subgrade measurement control 405, and other measurement controls 406. For example, when the user clicks on the bridge measurement control 401, the terminal device displays the bridge measurement interface, that is, the target large-range structure to be measured interface.

[0059] Step S203, obtain the first input data of the target large-range structure to be measured entered by the user through the target large-range structure to be measured interface.

[0060] Step S204, in response to the third selection operation of the user on the start measurement control, create a measurement request message according to the first input data.

[0061] Please refer to Figure 5 , Figure 5 FIG. is a schematic diagram of a target large-range structure to be measured interface provided by an embodiment of the present application. The target large-range structure to be measured interface 500 includes a target large-range structure input data area 501 and a start measurement control 502. The start measurement control 502 is used to obtain the third selection operation of the user. The target large-range structure input data area 501 includes a structure form data input box, a camera parameter input box, and a reference point information input box. The target large-range structure input data area 501 is used to obtain the input data entered by the user.

[0062] Among them, the user inputs the first input data in the target large-range structure input data area 501.

[0063] Among them, the first input data includes, but is not limited to, the structure form information of the structure to be measured, the coordinate information of the reference point, the parameter data of the camera, etc. The structure form information includes the structure form image taken, and the parameter data of the camera includes the focal length, field of view, number, and position information on the observation platform of the camera, etc.

[0064] Among them, the third selection operation is used to indicate the start of measuring the target large-range structure. The third selection operation can be a click operation or a touch operation on the start measurement control 502, and the terminal device creates a measurement request message.

[0065] Step S205, send the measurement request message to the processing device, and the processing device is used to respond to the measurement request message and send the measurement result information to the terminal device.

[0066] After receiving the measurement request message, the processing device performs corresponding measurement operations. For example, it controls a measurement camera to take pictures of historical points to be measured or newly added target points to be measured on a large-scale structure to be measured, obtains a captured image, analyzes the captured image to obtain a measurement result, and sends a measurement result message to the terminal device.

[0067] Step S206: Display a measurement result interface for displaying the measurement result information.

[0068] It can be seen that in the embodiment of the present application, the terminal device first responds to a first selection operation of the user on the large-scale structure to be measured measurement control in the measurement management interface of the structure to be measured, and displays a large-scale structure type selection interface. The large-scale structure type selection interface includes multiple structure type controls. Then, in response to a second selection operation of the user on the target structure type control in the large-scale structure type selection interface, it displays a measurement interface for the target large-scale structure to be measured. The measurement interface for the target large-scale structure to be measured includes an input data area for the target large-scale structure to be measured and a start measurement control. Further, it obtains the first input data of the target large-scale structure to be measured entered by the user through the measurement interface for the target large-scale structure to be measured. Furthermore, in response to a third selection operation of the user on the start measurement control, it creates a measurement request message according to the first input data, and then sends the measurement request message to the processing device. The processing device is used to respond to the measurement request message and send the measurement result information to the terminal device. Finally, it displays the measurement result interface, which is used to display the measurement result information. It is possible to realize the measurement of a large-scale structure by the structure deformation monitoring system through the terminal device responding to the selection operation of the user on the displayed measurement interface, analyzing the entered input data, creating and transmitting the measurement request message, and displaying the measurement result interface, and the processing device responding to the measurement request information to perform the measurement operation and return the measurement result information, which is beneficial to improving the intelligence of deformation measurement.

[0069] In a possible example, when the target large-scale structure to be measured is a target bridge, the first input data includes an image of the current structural form of the target bridge. When creating a measurement request message based on the first input data, the method may include the following steps: obtaining a historical structural form image of the target bridge, in which a plurality of historical points to be measured are marked, and the lateral distances of different historical points to be measured are different in the bridge coordinate system of the target bridge; determining a target component for which points to be measured need to be added according to the current structural form image and the historical structural form image; determining a layout rule for the target points to be measured of the target component; determining the layout positions and the number of target points to be added according to the layout rule for the target points to be measured; obtaining second input data of a target camera entered by the user through the large-scale structure to be measured measurement interface, where the target camera is used to capture images of the target points to be measured; and creating the measurement request message for the target points to be measured according to the information of the points to be measured of the target points to be measured and the second input data of the target camera.

[0070] Wherein, when the target large-scale structure to be measured is under construction, the structural form of the target large-scale structure is constantly changing. During this process, the places that need to be monitored on the target large-scale structure are constantly increasing or decreasing. Accordingly, the points to be measured need to be added or reduced in layout, and the number of corresponding measurement cameras also needs to be increased or reduced.

[0071] The target components include, but are not limited to, bridge piers, girders, and cable towers.

[0072] The terminal device includes a memory, and the memory is used to store the historical structural form image of the target bridge. The terminal device can compare and analyze the current structural form image and the historical structural form image to determine the target components for which points to be measured need to be added. It can identify the structural form of the target bridge, including the target components and the parameter information of the target components, through an image processing method. For example: if it is identified that the historical structural form image includes a bridge pier and the current structural form image includes a bridge pier and a girder, the girder is the target component for which points to be measured need to be added; if it is identified that the historical structural form image includes the first bridge pier and the current structural form image includes two bridge piers, the added bridge pier is the target component for which points to be measured need to be added; if it is identified that the historical structural form image includes a bridge pier and a girder, the number of bridge piers is four, and the length of the girder is 30 m, and the current structural form image includes a bridge pier and a girder, the number of bridge piers is four, and the length of the girder is 50 m, the girder is the target component for which points to be measured need to be added.

[0073] Among them, for different components of the bridge, the arrangement rules of the points to be measured are different. The arrangement rules of the points to be measured can be preset, and at the same time, the number of points to be measured can be increased or decreased according to the actual situation. Pier: Arrangement position of the point to be measured: the outer edge of the pier, Number of settings: 4, One point to be measured is arranged at each of the 4 outer edges. Beam body: Arrangement position of the point to be measured: the cross-section of the beam body, Number of settings: determined according to the length of the beam body, One point to be measured is arranged every 5 meters. Cable tower: Arrangement position of the point to be measured: the four corners at the bottom of the cable tower, Number of arrangements: 4 points to be measured are arranged for each cable tower.

[0074] Among them, the second input data includes the information of the points to be measured and the parameter data of the target camera, such as the focal length, field of view, number, and position information on the observation platform of the target camera. The information of the points to be measured includes the ID of the point to be measured and the position of the component to be arranged. For example: ID: L011, the position of the component to be arranged is the beam body.

[0075] Among them, the measurement request message includes the second input data and the information of the points to be measured of the target point to be measured.

[0076] Among them, the user can input the second input data in the input data area of the target large-range structure to be measured in the target large-range structure measurement interface.

[0077] It can be seen that in this example, the terminal device can analyze the target component that needs to add the points to be measured based on the current structural form image and the historical structural form image of the target bridge, and determine the arrangement position and the number of arrangements of the target points to be measured that need to be added, obtain the second input data entered by the user, create a measurement request message according to the information of the points to be measured of the target point to be measured and the second input data of the target camera, and realize the arrangement of the target points to be measured and the measurement of the newly added target points to be measured, which is beneficial to improving the intelligence of deformation measurement.

[0078] In a possible example, for determining the arrangement position and the number of arrangements of the target points to be measured that need to be added according to the arrangement rules of the target points to be measured, the above method may include the following steps: determining the historical measurement area of the target component according to the historical structural form image; determining the current measurement area of the target component according to the current structural form image; determining the target point to be measured arrangement area according to the current measurement area and the historical measurement area; positioning the target points to be measured that need to be measured in the point to be measured arrangement area according to the arrangement rules of the target points to be measured.

[0079] Among them, the area where the current measurement area increases compared with the historical measurement area is the target point to be measured arrangement area.

[0080] For example, the target point to be measured arrangement area is a 20m long beam body area, and the arrangement rule of the target points to be measured is to arrange one point to be measured every 5 meters at the cross-section of the beam body, then five new target points to be measured are added, and the interval between the five target points to be measured is 5 meters.

[0081] It can be seen that in this example, the terminal device can determine the target area for arranging the points to be measured, and further locate the target points to be measured based on the target rule for arranging the points to be measured, which is beneficial to improving the intelligence of determining the points to be measured.

[0082] In a possible example, after determining the arrangement positions and the number of target points to be added according to the target rule for arranging the points to be measured, the above method may include the following steps: marking the target area for arranging the points to be measured and the target points on the current structural form image; displaying an interface for arranging the points to be measured, where the interface for arranging the points to be measured includes the marked current structural form image.

[0083] Please refer to Figure 6 , Figure 6 FIG. 6 is a schematic diagram of an interface for arranging points to be measured provided by an embodiment of the present application. The interface 600 for arranging points to be measured includes a structural form display area 601, and the structural form display area 601 is used to display the marked current structural form image on the target large-range structure to be measured.

[0090] Among them, the control point is a target placed in the field of view of the target camera for measuring the internal and external parameters of the target camera. The number of cooperative targets can be one or more, which is not limited here.

[0091] Among them, determining the first conversion relationship according to the third image point coordinates and the first coordinates includes the following steps: establishing a camera calibration formula between the first coordinates and the third image point coordinates; establishing a least squares optimization equation according to the calibration formula; solving the least squares optimization equation to obtain the target external parameters, and taking the target external parameters as the first conversion relationship.

[0092] Among them, the camera calibration formula is as follows: λ is the scale factor, K is the internal parameter matrix of the camera, G TS,Cis the first conversion relationship, and the third image point coordinates are denoted as The first coordinate is denoted as The non - linear least squares optimization equation is as follows: The camera is denoted as C i , and the moment when the calibration work is carried out is denoted as t i , t i The total station coordinate system at time t It is calculated that at time t i the first conversion relationship between C i and is:

[0093] Among them, the external parameter matrix of the camera coordinate system of each camera relative to the total station coordinate system can be obtained. In this way, the rigid body transformation between any two cameras at the initial monitoring time t0 can be derived through the total station coordinate system as an intermediate reference system, as shown in the following formula:

[0094]

[0095] Furthermore, it can be determined that the rigid body transformation between any two cameras at time t1 can be derived through the total station coordinate system as an intermediate reference system, as shown in the following formula:

[0096]

[0097] Among them, the relationship between the total station coordinate system i at time t and the reference coordinate system W can be decomposed into a rotation around the coordinate origin once and a translation once, as shown in the following formula: The number of reference points is three. Based on the first coordinates of the three reference points, the fourth coordinate of the origin of the total station coordinate system in the reference coordinate system can be calculated Substitute the first coordinates of the three reference points into the relationship formula between the total station coordinate system and the reference coordinate system, and calculate the rotation relationship i between the total station at time t and the measurement reference coordinate system i The conversion relationship between the total station at time t and the measurement reference coordinate system can be expressed as: i where time t j is the first time point, and time t

[0098] Among them, considering that the total station itself may also have a certain displacement during the time interval between the first time point and the second time point, when determining the transformation relationship between the camera coordinate system and the reference coordinate system with the help of the total station coordinate system, it is necessary to first determine the transformation relationship between the total station coordinate system at the first time point and the total station coordinate system at the second time point, that is, the seventh transformation relationship. Then, according to the third transformation relationship = the first transformation relationship × the second transformation relationship × the seventh transformation relationship, the first transformation relationship between the camera coordinate system and the reference coordinate system at the second time point is determined.

[0099] Among them, a reflecting prism can be installed on the stabilizing pier as the geodetic reference point, assuming that the geodetic reference point remains unchanged, and the transformation relationship between the total station coordinate systems at two time points can be calculated according to the following resection calibration formula:

Further, based on the aforementioned resection calibration formula, the transformation relationship between the total station coordinate system at the first time point and the total station coordinate system at the second time point can be calculated, that is, the seventh transformation relationship.

[0102] Among them, the fourth transformation relationship is the transformation relationship between the observation platform coordinate system and the reference coordinate system at the second time point. It is necessary to first determine the six-degree-of-freedom change amount of the observation platform during the time interval between the first time point and the second time point. The fourth transformation relationship = the sixth transformation relationship × (the six-degree-of-freedom change amount generated by the observation platform during the time interval between the first time point and the second time point). The sixth transformation relationship is the transformation relationship between the observation platform coordinate system and the reference coordinate system at the first time point. The sixth transformation relationship = the initial transformation relationship × (the six-degree-of-freedom change amount generated by the observation platform during the time interval between the initial moment and the first time point), that is is the transformation relationship between the observation platform and the reference coordinate system at the initial t0 moment, that is, the initial transformation relationship, is the six-degree-of-freedom change amount generated by the observation platform during the time interval between the initial moment and the first time point, is the sixth transformation relationship.

[0103] Among them, the fifth transformation relationship = the third transformation relationship × the fourth transformation relationship.

[0104] Among them, the relational expressions of the coordinate change amount, the fifth transformation relationship, and the displacement change amount are as follows:

[0105]

[0106] Among them, represents the target displacement change amount, represents the coordinate change amount, represents the six-degree-of-freedom change amount that occurs between the observation platform at t i and t j The unit matrix I is a square matrix with elements on the diagonal (referred to as the main diagonal) from the upper left corner to the lower right corner all being 1, and all other elements being 0. The target displacement change amount can be calculated based on this relationship.

[0107] It can be seen that in this example, the terminal device displays the device measurement data in the device measurement data display area, the conversion relationship data in the coordinate system relationship display area, and the measurement result data of the point to be measured in the measurement result display area, which is beneficial to improving the intelligence of deformation monitoring.
