When monitoring personnel are monitoring the tunnel, the following are known initial parameters: the method comprises the following steps of (1) position coordinates of each monitoring station, coordinates of each monitoring mark, an identifier of each monitoring station, an identifier of each monitoring mark, a direction and an identifier of each electronic device in each monitoring station, a zoom ratio of each electronic device corresponding to a current monitoring mark, and an initial pitch angle of each monitoring station; the distance parameter is the horizontal distance between the monitoring station and the monitoring sign. It is to be understood that, before the column equation set, the data that may be used above may be obtained by querying from a stored database, or may be obtained by invoking, which is not limited herein, and may be obtained before the column equation set.
103. And calculating the deformation of the tunnel according to the M images, the initial parameters of at least one electronic device corresponding to each monitoring station and the distance parameters between each point to be measured and two or more corresponding monitoring stations.
Firstly, the settlement amount of the monitoring mark in the image in the vertical direction is obtained through the shot image according to the image coordinate scale, wherein before the settlement amount corresponding to the scale is obtained, the image can be subjected to homologous point sub-pixel positioning, and the image can be subjected to adaptive template filtering, adaptive threshold processing, gray-scale image fitting, image enhancement processing and the like.
Further, the equation may be formulated according to the calculation of the amount of displacement in the vertical direction. Wherein, the calculation formula of the column equation may be: the vertical displacement of the first monitoring mark in the image is the zoom magnification of the first electronic device in the monitoring station corresponding to the first monitoring mark (vertical displacement of the first monitoring mark-vertical displacement of the monitoring station +/-horizontal distance x sin (pitch angle increment of the monitoring station) between the monitoring station and the first monitoring mark). The vertical displacement of the first monitoring mark, the zoom factor of the first electronic device in the monitoring station corresponding to the first electronic device, and the horizontal distance between the monitoring station and the first electronic device are known. What needs to be solved by the simultaneous equations is the vertical displacement of the monitoring station and the first monitored vertical displacement, and the obtained unknown number is taken as the deformation of the target position.
In the embodiment of the application, W monitoring stations are arranged in a tunnel in advance, wherein at least one point to be measured is arranged on W-1 monitoring stations except an initial monitoring station in the W monitoring stations, each monitoring station is provided with at least one electronic device, the shooting directions of all the electronic devices are the same direction, each point to be measured corresponds to at least one image, at least one image corresponding to each point to be measured is shot by the electronic devices on two or more monitoring stations corresponding to each point to be measured, after the images are acquired, acquiring initial parameters of at least one electronic device corresponding to each monitoring station in the W monitoring stations and distance parameters between each point to be measured and two adjacent monitoring stations, and calculating the settlement of the point to be measured by constructing an equation set and simultaneously solving to represent the settlement of the tunnel.
Referring to fig. 6, fig. 6 is a schematic flowchart of another tunnel deformation monitoring method according to an embodiment of the present invention, and as shown in fig. 6, the tunnel deformation monitoring method includes:
601. and constructing a first equation group according to a calculation formula of the displacement of the monitoring mark in the vertical direction in the image.
Specifically, taking the setting scheme in fig. 3 as an example for explanation, with the monitoring station and the monitoring flag set in fig. 3, equation set (1) can be listed:
therein, with a monitoring station C i For example, two monitoring marks M are photographed respectively i+1 And M i+2 Wherein the upper right of each parameter is labeled the number of the electronic device, the lower right is the monitor tag number,
to monitor the amount of vertical displacement of the marker M in the image of the electronic device C,
the scaling factor of the mark M is the electronic equipment C, the deltay is the settlement amount of the electronic equipment in the monitoring mark or the monitoring station,
is the horizontal distance, θ, between the monitoring station and the monitoring marker M C Is the pitch angle increment of the monitoring station. The value of h can be obtained by calculating the coordinate of a corresponding image scale, and the specific values of k and d can be calibrated when the values are set in the tunnelTo obtain Δ y M And Δ y C For monitoring quantity, it is an unknown number to be solved, and if one direction is selected as positive direction, then at last
Is positive and the opposite direction is negative, wherein deltay is due to the monitoring flag being set at the location of the monitoring station M And Δ y C The correspondence is equal.
Thus, the nth monitoring station may list equation (2) as:
further, as in the arrangement of fig. 4, the following equation (3) may be listed on the basis of the above equation set (1):
602. and simultaneously solving the first equation group to obtain a solution result, wherein the solution result comprises the settlement amount of each monitoring mark in the first equation group.
In one possible implementation, in listing the above equation set (1), it is to be understood that equation set (1) is only one equation set listed by one monitoring station, and in the case of n monitoring stations, n equation sets may be listed, where there are n monitoring stations, but 2n equations may be listed, but 2n +2 unknowns: the pitch angle variable quantity of n monitoring stations, the settlement quantity of n monitoring stations and the settlement quantity of 2 monitoring signs. Thus, when the amount of settling of at least two monitoring signs is known, the amount of settling of the other monitoring signs can be solved by a linear least squares method.
Furthermore, the settlement amount of each monitoring sign, the pitch angle variation of n monitoring stations, the settlement amount of n monitoring stations, the pitch angle variation of n monitoring stations and the settlement amount of n monitoring stations are solved by the equations (1) and (2), and the settlement amounts corresponding to the rest monitoring signs are solved by substituting the pitch angle variation of n monitoring stations and the settlement amount of n monitoring stations into the equation set (3). It can be understood that, in the M images, when the settlement amount occurring at the position of the monitoring station is the same as the settlement amount occurring at the position of the monitoring mark and only one settlement occurs, the image may be captured, and monitoring personnel can hardly judge whether the monitoring station or the position of the to-be-measured point where the monitoring mark is positioned is settled according to the image, therefore, the settlement amount of the monitoring station and the monitoring mark respectively obtained by the equation set (1) and the equation set (2) can be substituted into the equation set (3), the measured results can be corrected so as to obtain the settlement amount of the monitoring mark in different depth of field ranges, the settlement amount is a settlement deformation parameter of the point to be measured, an equation set and the known settlement point are used for solving, the influence caused by instability of the monitoring station can be effectively eliminated, and the measurement precision is improved.

Specifically, after the settlement amount of each monitoring mark is obtained, the position where the monitoring mark is located is marked as the deformation amount of the target position of the tunnel.
