On the contrary, these embodiments are provided so that the present application can be more thoroughly understood and the scope of the present application can be accurately conveyed to those skilled in the art.
[0045] Embodiment one
[0046] The embodiment one of the present application discloses a method for determining a corner reflector deployment scheme, referring to Figure 1 , the method for determining a corner reflector deployment scheme comprises:
[0047] Step S110, obtaining the environment parameters corresponding to the to-be-deployed point and the running trajectory of the probe;
[0048] In this embodiment, the to-be-deployed point can be pre-set according to the construction drawings or map of the construction site, and the environment parameters are the parameters required to meet the deployment conditions. The probe can be a radar, and the running trajectory is the projection of the probe trajectory on the earth's surface.
[0049] As an optional implementation, the environment parameters can be at least one of radio interference value, power transmission interference value, satellite signal strength value, latitude and longitude coordinates, and optical image.
[0050] Step S120, determining a distance straight line corresponding to the to-be-deployed point according to the running trajectory, and determining a to-be-selected deployment point according to the environment parameters;
[0051] In this embodiment, the distance straight line is perpendicular to the running trajectory on the horizontal plane, i.e. the distance straight line and the running trajectory form an orthogonal coordinate system on the horizontal plane. The to-be-selected deployment point is selected according to whether the environment parameters meet the pre-set deployment conditions.
[0052] As an optional implementation, the projection of the running trajectory on the plane where the to-be-deployed point is located is determined, and a straight line perpendicular to the projection on the plane is taken as the distance straight line.
[0053] Optionally, step S120 comprises:
[0054] Step S121, obtaining the incident signal cross section of the probe at the latitude and longitude coordinates;
[0055] Step S122, determining the to-be-deployed point where the incident signal cross section does not exist obstacles according to the optical image;
[0056] In step S123, a signal interference value of the to-be-deployed point is determined based on the environment parameter, and the to-be-deployed point position that meets the preset deployment condition is screened out as the to-be-selected deployment point position.
[0057] In this embodiment, the probe signal emitted by the probe to a point can be regarded as a cone, the vertex of the cone being the probe, and the bottom surface being the plane where the to-be-deployed point position is located.
[0058] As an optional implementation, the latitude and longitude coordinates of the to-be-deployed point position are determined, the cross section of the incident signal of the probe at the latitude and longitude coordinates is obtained, and it is determined whether there is an obstacle between the to-be-deployed point position and the probe according to the obtained optical image, and the to-be-deployed point position without the obstacle is selected. The to-be-deployed point position without the obstacle is determined, the signal interference value is determined based on the environment parameter of the to-be-deployed point position, and the to-be-deployed point position that meets the preset deployment condition is screened out as the to-be-selected deployment point position.
[0059] For example, based on the obtained environment parameter, a corresponding weight value is determined for each environment parameter according to a preset calculation formula, and then the signal interference value is calculated.
[0060] For example, the obtained environment parameter is regarded as the signal interference value, and when each environment parameter meets the corresponding deployment condition, the to-be-deployed point position is determined as the to-be-selected deployment point position.
[0061] Optionally, step S123 includes:
[0062] In step S1231, the three-dimensional coordinates of the to-be-deployed point position are obtained, and the radar coordinates corresponding to the to-be-deployed point position are calculated in combination with the three-dimensional coordinates and the latitude and longitude coordinates.
[0063] In step S1232, a radar map is obtained, and the background reflection intensity value at the radar coordinates is determined.
[0064] In step S1233, when the background reflection intensity value is less than or equal to a first threshold value, the radio interference value is less than or equal to a second threshold value, the power transmission interference value is less than or equal to a third threshold value, and the satellite signal intensity value is greater than or equal to a fourth threshold value, the to-be-deployed point position is determined as the to-be-selected deployment point position.
[0065] As an optional implementation, laser point cloud data at the to-be-deployed point is collected to establish a three-dimensional model at the to-be-deployed point; three-dimensional coordinates of the to-be-deployed point in the three-dimensional model are determined, and the radar coordinates of the to-be-deployed point are inversely deduced according to a preset algorithm in combination with the three-dimensional coordinates and the latitude and longitude coordinates; a radar map corresponding to the probe is acquired, and the background reflection intensity value at the to-be-deployed point is determined according to radar data in the radar map; when the background reflection intensity value is less than or equal to a first threshold value, the radio interference value is less than or equal to a second threshold value, the power transmission interference value is less than or equal to a third threshold value, and the satellite signal strength value is greater than or equal to the third threshold value, the to-be-deployed point is determined as the to-be-selected deployment point. The first threshold value, the second threshold value, and the third threshold value are predetermined.
[0066] In step S130, a first line parallel to the running track and a second line parallel to the distance-to-straight line are determined in a line between adjacent to-be-selected deployment points.
[0067] In step S140, the to-be-selected deployment points corresponding to the first line with a length greater than the directional effect distance and / or the second line with a length greater than the distance-to-direction effect distance are target deployment points.
[0068] In the embodiment, the line is a straight line between adjacent to-be-selected deployment points, and the directional effect distance and the distance-to-direction effect distance are minimum distances in two perpendicular directions that do not produce sidelobe effects. When the distance between to-be-selected deployment points is less than the directional effect distance or the distance-to-direction effect distance, sidelobe effects are produced when a corner reflector is deployed at the point.
[0069] As an optional implementation, a line between adjacent to-be-selected deployment points is determined, a line parallel to the running track is selected as a first line, a line parallel to the distance-to-straight line is selected as a second line, a first line with a length greater than the directional effect distance and a second line with a length greater than the distance-to-direction effect distance are determined, and to-be-selected deployment points at the end points of the first line and the second line are target deployment points.
[0070] For example, the line between point one and point two can be greater than the directional effect distance or the distance-to-direction effect distance, but the line between point two and point three can be less than the directional effect distance or the distance-to-direction effect distance, in which case point two should be determined as a target deployment point, and point three is not a target deployment point.
[0071] In step S150, a corner reflector deployment scheme is generated according to the coordinates of the target deployment point.
[0072] Optionally, step S150 includes:
[0073] Step S151, determining an unqualified deployment point where the length of the first line is less than the directional effect distance, or the length of the second line is less than the distance effect distance.
[0074] Step S152, removing the unqualified deployment point, and generating the corner reflector deployment scheme according to the latitude and longitude coordinates of the screened target deployment point.
[0075] As an optional implementation, the unqualified deployment point where the length of the first line is less than the directional effect distance, or the length of the second line is less than the distance effect distance, is determined, wherein when the length of the line between a certain unqualified deployment point and point one is less than the directional effect distance or the distance effect distance, but the length of the line between the unqualified deployment point and point two is greater than the directional effect distance or the distance effect distance, the unqualified deployment point should be determined as a target deployment point. The unqualified deployment point is removed, and the corner reflector deployment scheme is generated according to the latitude and longitude coordinates of the screened target deployment point, wherein the scheme further includes the elevation angle of the corner reflector installation.
[0076] Optionally, the optical image at the target deployment point is analyzed, and a point that does not meet the installation condition is screened out as an unqualified point. For example, there is water leakage or other harsh conditions at the point.
[0077] The technical solutions in the embodiments of the present application have at least the following technical effects or advantages:
[0078] Since the environment parameters corresponding to the to-be-deployed point and the running track of the probe are acquired, the distance direction straight line corresponding to the to-be-deployed point is determined according to the running track, the to-be-deployed point is determined according to the environment parameters, the first line parallel to the running track and the second line parallel to the distance direction straight line are determined in the line between the adjacent to-be-deployed points, the to-be-deployed point corresponding to the first line with a length greater than the directional effect distance and / or the second line with a length greater than the distance effect distance is determined as a target deployment point, and the corner reflector deployment scheme is generated according to the coordinates of the target deployment point, the technical problem that the anti-interference ability of the corner reflector is poor in the related art, the monitoring precision is low, and the three-dimensional deformation monitoring demand cannot be met is effectively solved, and the technical effect that the building deformation degree is accurately detected is achieved.
[0079] Embodiment two
[0080] Based on embodiment one, embodiment two 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 corresponding to the running track of the probe, and the distance direction resolution corresponding to the distance direction straight line.
[0082] obtaining a preset direction effect parameter and a distance direction effect parameter;
[0083] determining the direction effect distance according to the direction resolution and the direction effect parameter, and determining the distance direction effect distance according to the distance direction resolution and the distance direction effect parameter.
[0084] In the embodiment, the direction resolution is information obtained by the detector, resolution in the direction of the running track, and the distance direction resolution is information obtained by the detector, resolution in the direction of the distance direction. The direction effect parameter and the distance direction effect parameter are determined according to experimental data.
[0085] As an optional implementation, the direction resolution in the direction of the running track is determined, the distance direction resolution in the direction of the distance direction is determined, the obtained direction resolution and distance direction resolution are averaged respectively to obtain the direction resolution and distance direction resolution. The preset direction effect parameter and distance direction effect parameter are obtained. The direction effect distance is obtained by multiplying the direction resolution by the direction effect parameter. The distance direction effect distance is obtained by multiplying the distance direction resolution by the distance direction effect parameter.
[0086] The technical solutions in the embodiments of the present application have at least the following technical effects or advantages:
[0087] Since the direction effect distance is determined according to the direction resolution and the direction effect parameter, and the distance direction effect distance is determined according to the distance direction resolution and the distance direction effect parameter, the technical problem of side lobe effect existing in the installation of corner reflectors in the related art is effectively solved, and the side lobe effect between corner reflectors is effectively and conveniently avoided.
[0088] Embodiment Three
[0089] Based on Embodiment One, Embodiment Three of the present application provides a method for determining a corner reflector deployment scheme, referring to Figure 3 , step S130 comprises:
[0090] Step S310, determining a line connecting adjacent candidate deployment points.
[0091] Step S320, determining a first included angle between the line and the running track, and a second included angle between the line and the distance direction straight line.
[0092] Step S330, when the first included angle is less than a first preset angle, determining that the line is the first line.
[0093] Step S340, when the second included angle is less than the second preset angle, determining that the line is the second line.
[0094] In the embodiment, when the included angle between the line connecting the candidate deployment point and the running track or the distance direction straight line is less than the preset angle, it is determined that the line is parallel to the running track or the distance direction straight line.
[0095] As an optional implementation, the line connecting the adjacent candidate deployment points is determined, the included angle between each line and the running track is determined as a first included angle, and the included angle between each line and the distance direction straight line is determined as a second included angle. When the first included angle is less than a first preset angle, it is determined that the line is a first line. When the second included angle is less than a second preset angle, it is determined that the line is a second 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, and vice versa.
[0097] For example, the first preset angle is 30 degrees, and the second preset angle is 25 degrees.
[0098] Optionally, before step S150, the method further comprises:
[0099] Step S350, when the first included angle is greater than the first preset angle, and the second included angle is greater than the second preset angle, determining that the candidate deployment point is the target deployment point.
[0100] As an optional implementation, when the first included angle is greater than the first preset angle, and the second included angle of the line is greater than the second preset angle, it is determined that the two candidate deployment points corresponding to the line are target deployment points.
[0101] For example, if the line between the two candidate deployment points and other candidate deployment points does not exist the first line or the second line, it is determined that the two candidate deployment points corresponding to the line are target deployment points.
[0102] For example, if the line between the two candidate deployment points and other candidate deployment points exists the first line or the second line, it is necessary to re-determine whether the length of the first line or the second line is greater than the direction effect distance or the distance direction effect distance.
[0103] Optionally, the finally determined target deployment point does not exist any first line or second line with other target deployment points, or the length of the existing first line is greater than the direction effect distance, and the length of the existing second line is greater than the distance direction effect distance.
[0104] The technical solutions in the embodiments of the application have at least the following technical effects or advantages:
[0105] By determining the line connecting the adjacent candidate deployment points, determining the first angle between the line and the running track and the second angle between the line and the distance straight line, determining the line as the first line when the first angle is less than the first preset angle, and determining the line as the second line when the second angle is less than the second preset angle, the technical problem that the anti-interference ability of the corner reflector is poor in the related art, resulting in low monitoring accuracy and failing to meet the three-dimensional deformation monitoring requirement is effectively solved, and the technical effect of accurately detecting the building deformation degree is achieved.
