[0045] Embodiment 1
[0046] Embodiment 1 of the present application discloses a method for determining a corner reflector deployment scheme, referring to Figure 1 , the method for determining the corner reflector deployment scheme includes:
[0047] Step S110, obtaining environmental parameters corresponding to the points to be deployed and the running trajectory of the detector;
[0048] In this embodiment, the points to be deployed can be pre-set according to the architectural drawings or maps of the construction site, and the environmental parameters are the parameters required to meet the deployment conditions. The detector can be a radar, and the running track is the projection of the detector's trajectory around the earth on the earth's surface.
[0049] As an optional implementation manner, the environmental parameter may be at least one of a radio interference value, a power transmission interference value, a satellite signal strength value, a latitude and longitude coordinates, and an optical image.
[0050] Step S120, determining the distance straight line corresponding to the to-be-deployed point according to the running trajectory, and determining the to-be-selected deployment point according to the environmental parameters;
[0051] In this embodiment, the distance straight line is perpendicular to the running track on the ground plane, that is, the distance straight line and the running track form a rectangular coordinate system on the ground plane. The deployment points to be selected are screened according to whether the environmental parameters meet the preset deployment conditions.
[0052] As an optional implementation, the projection of the running trajectory on the plane where the point to be deployed is located is determined, and a straight line on the plane that is perpendicular to the projection is used as the distance straight line.
[0053] Optionally, step S120 includes:
[0054] Step S121, obtaining the incident signal cross section of the detector at the latitude and longitude coordinates;
[0055] Step S122, determining, according to the optical image, a point to be deployed where no obstacle exists in the incident signal cross section;
[0056] Step S123, determining the signal interference value of the to-be-deployed point based on the environmental parameters, and screening the to-be-selected deployment points whose signal interference values meet the preset deployment conditions.
[0057] In this embodiment, the detection signal emitted by the detector to a point can be regarded as a cone, the vertex of the cone is the detector, and the bottom surface is the plane where the point to be deployed is located.
[0058] As an optional implementation, determine the longitude and latitude coordinates of the point to be deployed, obtain the cross section of the incident signal of the detector at the longitude and latitude coordinates, determine whether there is an obstacle between the point to be deployed and the detector based on the acquired optical image, and select the point to be deployed without obstacles. Determine the point to be deployed without obstacles; determine the signal interference value based on the environmental parameters of the point to be deployed, and select the point to be deployed whose signal interference value meets the preset deployment conditions as the selected deployment point.
[0059] Exemplarily, based on the acquired environmental parameters, a corresponding weight value is determined for each environmental parameter according to a preset calculation formula, and then the signal interference value is calculated.
[0060] Exemplarily, the acquired environmental parameters are all regarded as signal interference values, and when each environmental parameter satisfies the corresponding deployment condition, the to-be-deployed point is determined as a to-be-selected deployment point.
[0061] Optionally, step S123 includes:
[0062] Step S1231, obtaining the three-dimensional coordinates of the point to be deployed, and calculating the radar coordinates corresponding to the point to be deployed by combining the three-dimensional coordinates and the longitude and latitude coordinates;
[0063] Step S1232, obtaining a radar map, and determining the background reflection intensity value at the radar coordinates;
[0064] Step S1233, when the background reflection intensity value is less than or equal to the first threshold, the radio interference value is less than or equal to the second threshold, the power transmission interference value is less than or equal to the third threshold, and the satellite signal strength value is greater than or equal to the third threshold, the to-be-deployed point is determined to be the to-be-selected deployment point.
[0065] As an optional implementation, collect laser point cloud data at the point to be deployed to establish a three-dimensional model of the point to be deployed; determine the three-dimensional coordinates of the point to be deployed in the three-dimensional model, and combine the three-dimensional coordinates and the longitude and latitude coordinates to infer the radar coordinates of the point to be deployed according to a preset algorithm; obtain the radar map corresponding to the detector, and determine the background reflection intensity value at the point to be deployed according to the radar data in the radar map; when the background reflection intensity value is less than or equal to the first threshold, the radio interference value is less than or equal to the second threshold, the power transmission interference value is less than or equal to the third threshold, and the satellite signal strength value is greater than or equal to the third threshold, determine that the point to be deployed is the selected deployment point. The first threshold, the second threshold, and the third threshold are predetermined.
[0066] Step S130, determining, among the lines corresponding to the adjacent to-be-selected deployment points, a first line parallel to the running track and a second line parallel to the distance straight line;
[0067] Step S140, taking the candidate deployment point corresponding to the first link whose length is greater than the directional effect distance and / or the second link whose length is greater than the distance effect distance as the target deployment point;
[0068] In this embodiment, the connecting line is a straight line between adjacent candidate deployment points, and the directional effect distance and the distance effect distance are the minimum distances in two perpendicular directions without generating a side lobe effect. When the distance between the candidate deployment points is less than the directional effect distance or the distance effect distance, deploying a corner reflector at this point will generate a side lobe effect.
[0069] As an optional implementation, determine the connecting lines between adjacent candidate deployment points, select the connecting line parallel to the running trajectory as the first connecting line; select the connecting line parallel to the distance straight line as the second connecting line; determine the first connecting line whose length is greater than the directional effect distance and the second connecting line whose length is greater than the distance effect distance; and use the candidate deployment points at the endpoints of the above-mentioned first connecting line and the second connecting line as the target deployment points.
[0070] For example, it may happen that the line connecting point one and point two is greater than the directional effect distance or the distance effect distance, but the line connecting point two and point three is less than the directional effect distance or the distance effect distance. At this time, point two should be determined as the target deployment point, while point three is not the target deployment point.

[0074] Step S152, removing the unqualified deployment points, and generating the corner reflector deployment plan according to the latitude and longitude coordinates of the screened target deployment points.
[0075] As an optional implementation, determine the unqualified deployment points where the length of the first connecting line is less than the directional effect distance, or the second connecting line is less than the distance effect distance, wherein when the connecting line between an unqualified deployment point and point one is less than the directional effect distance or the distance effect distance, but the length of the connecting line with point two is greater than the directional effect distance or the distance effect distance, it should be determined as a target deployment point. Remove the unqualified deployment points, and generate a corner reflector deployment plan based on the latitude and longitude coordinates of the screened target deployment points, wherein the plan also includes the elevation angle of the corner reflector installation.
[0076] Optionally, the optical images at the target deployment points are analyzed to screen out points that do not meet the installation conditions as unqualified points. For example, there is water leakage or other adverse conditions at the points.
[0077] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:
[0078] The method adopts the following steps: obtaining the environmental parameters corresponding to the point to be deployed and the running trajectory of the detector; determining the distance straight line corresponding to the point to be deployed according to the running trajectory, and determining the selected deployment point according to the environmental parameters; determining the first line parallel to the running trajectory and the second line parallel to the distance straight line among the lines corresponding to the adjacent selected deployment points; taking the selected deployment point corresponding to the first line whose length is greater than the directional effect distance and / or the second line whose length is greater than the distance effect distance as the target deployment point; generating the corner reflector deployment plan according to the coordinates of the target deployment point. Therefore, the technical problem that the corner reflector has poor anti-interference ability, resulting in low monitoring accuracy and cannot meet the three-dimensional deformation monitoring requirements in the related technology is effectively solved, thereby achieving the technical effect of accurately detecting the degree of building deformation.
[0079] Embodiment 2
[0080] Based on the first embodiment, the second embodiment of the present application proposes a method for determining a corner reflector deployment scheme, referring to Figure 2 , before step S140, further comprising:
[0081] Step S210, determining the directional resolution of the detector corresponding to the running track, and the range resolution corresponding to the range straight line;
[0082] Step S220, obtaining preset directional effect parameters and distance effect parameters;
[0083] Step S230: determining the directional effect distance according to the directional resolution and the directional effect parameter, and determining the distance effect distance according to the distance resolution and the distance effect parameter.
[0084] In this embodiment, the directional resolution is the resolution of the information acquired by the detector in the direction of the running track, and the range resolution is the resolution of the information acquired by the detector in the range straight line direction. The directional effect parameter and the range effect parameter are determined based on experimental data.
[0085] As an optional implementation, the directional resolution of the detector in the direction of the running track is determined, and the range resolution in the range straight line direction is determined, and the obtained directional resolution and range resolution are averaged to obtain the directional resolution and the range resolution. The preset directional effect parameter and the range effect parameter are obtained; the directional resolution is multiplied by the directional effect parameter to obtain the directional effect distance; the range resolution is multiplied by the range effect parameter to obtain the range effect distance.
[0086] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:
[0087] Since the directional effect distance is determined according to the directional resolution and the directional effect parameter, and the distance effect distance is determined according to the distance resolution and the distance effect parameter, the technical problem of the side lobe effect when the corner reflector is installed in the related technology is effectively solved, thereby achieving effective and convenient avoidance of the side lobe effect between corner reflectors.
[0088] Embodiment 3
[0089] Based on Example 1, Example 3 of the present application proposes a method for determining a corner reflector deployment scheme, referring to Figure 3 , step S130 includes:
[0090] Step S310, determining the connection lines between the adjacent candidate deployment points;
[0091] Step S320, determining a first angle between the connecting line and the running track, and a second angle between the connecting line and the distance straight line;
[0092] Step S330, when the first angle is less than a first preset angle, determining the connecting line to be the first connecting line;
[0093] Step S340: when the second included angle is smaller than the second preset angle, determining the connecting line as the second connecting line.
[0094] In this embodiment, when the angle between the connecting line between the candidate deployment points and the running trajectory or the distance straight line is less than a preset angle, it is also determined that the connecting line is parallel to the running trajectory or the distance straight line.
[0095] As an optional implementation, determine the connecting lines between adjacent to-be-selected deployment points, determine the angle between each connecting line and the running trajectory as the first angle; determine the angle between each connecting line and the distance straight line as the second angle; when the first angle is less than the first preset angle, determine the connecting line as the first connecting line; when the second angle is less than the second preset angle, determine the connecting line as the second connecting line.
[0096] For example, according to the resolution of the detector, when the resolution is smaller, that is, the detection accuracy is higher, the preset angle is smaller; otherwise, it is larger.
[0097] Exemplarily, the first preset angle is 30 degrees, and the second preset angle is 25 degrees.
[0098] Optionally, before step S150, the method further includes:
[0099] Step S350: When the first angle is greater than the first preset angle, and the second angle is greater than the second preset angle, determining the candidate deployment point as the target deployment point.
[0100] As an optional implementation, when the first angle is greater than the first preset angle and the second angle of the line is greater than the second preset angle, the two candidate deployment points corresponding to the line are determined to be target deployment points.
[0101] Exemplarily, if there is no first connection line or second connection line between the two candidate deployment points and other candidate deployment points, the two candidate deployment points corresponding to the connection line are determined to be target deployment points.
[0102] For example, if there is a first connection line or a second connection line between the two candidate deployment points and other candidate deployment points, it is necessary to re-determine whether the length of the first connection line or the second connection line is greater than the directional effect distance or the distance effect distance.
[0103] Optionally, the finally determined target deployment point does not have any first line or second line with other target deployment points, or the lengths of the existing first lines are greater than the directional effect distance; the lengths of the existing second lines are greater than the distance effect distance.
[0104] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:
[0105] Since the method adopts the method of determining the connecting line between the adjacent selected deployment points, determining the first angle between the connecting line and the running track, and the second angle between the connecting line and the distance straight line, when the first angle is less than the first preset angle, determining the connecting line as the first connecting line, and when the second angle is less than the second preset angle, determining the connecting line as the second connecting line, the technical problem that the corner reflector in the related technology has poor anti-interference ability, resulting in low monitoring accuracy and cannot meet the three-dimensional deformation monitoring requirements is effectively solved, thereby achieving the technical effect of accurately detecting the degree of building deformation.
