Description

Technical Field

[0002] With the development of urban construction and the gradual rise of digital city technology, the detection of roads, underground pipelines and bridges is becoming increasingly important.

[0003] Existing detection technologies use detection equipment and follow a fixed detection pattern, that is, detecting by connecting measurement points between different survey lines. The processing software then segments the survey lines by generating a processing mesh. However, when generating the final 3D file, the data processing efficiency is low because each mesh needs to be processed individually and the data from other processed meshes needs to be correlated during the processing.

[0004] At the same time, the increase in the number of grids processed leads to logical time waste and low computational efficiency. Summary of the Invention

[0046] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0047] It should be noted that the terms "one aspect," "another aspect," "objective," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0048] Example 1

[0049] Figure 1This is a flowchart of a survey line segmentation method according to Embodiment 1 of the present invention. This embodiment is applicable to the processing of probe data. The method can be executed by a survey line segmentation device, which can be implemented in hardware and / or software. The survey line segmentation device can be configured in an electronic device with data processing capabilities. Figure 1 As shown, the method includes:

[0050] S110, draw survey lines based on the measurement data of the object being measured.

[0051] The technical solution of this embodiment can be executed by data processing software or electronic devices containing data processing software, and is suitable for scenarios where ground-penetrating radar performs data detection according to individual measurement points or pre-arranged measurement lines. For example, it can perform multi-channel detection of road surfaces, read the detection data through software, and then process the data.

[0052] The survey line can be an observation line composed of observation points arranged along a straight line at a certain scale. The object being measured can be roads, underground pipelines, underground lines, and bridges, etc. The measurement data can be coordinate data, returned radar wave data, etc.

[0053] The process involves measuring the object under test using radar, reading the measurement data, and then drawing a survey line based on the coordinates of the measured points, either by connecting the points one by one or by connecting the first and last points.

[0054] S120, Read the direction of the survey line and determine the drawing direction of the feature line based on the direction of the survey line.

[0055] The characteristic line can be a straight line or a curve used to represent the overall direction of one or more survey lines. For example, the characteristic line can be one of all survey lines. By selecting this survey line as the characteristic line, the number of survey lines on both sides of the characteristic line can be made similar.

[0056] The characteristic lines include the boundary lines or center lines of the survey lines. The boundary lines can be drawn on one side of the survey line, close to it. The boundary lines can be drawn along the direction of the survey line, and can be straight lines or curves. The center lines can be drawn along the direction of the survey line, and are located at the center of the area covered by one or more survey lines.

[0057] In this embodiment, optionally, reading the survey line direction and determining the drawing direction of the feature line based on the survey line direction includes:

[0058] The direction of the survey line is read based on the measurement data of the survey line.

[0059] If the survey line is a straight line, the drawing direction of the feature line is determined according to the direction of the survey line, and the starting and ending positions of the feature line are determined according to the measurement data of the survey line. The starting position can be the center of the farthest end of the survey line or a point within one grid cell near the survey line and extending beyond its range. The ending position can be the end of the survey line relative to the starting position, along its direction, or a point within one grid cell beyond the end of the survey line.

[0060] The grid can be a 50-meter by 25-meter square, with a length of 50 meters and a width of 25 meters.

[0061] Specifically, the coordinate data of the measuring points determined by the measurement data are used to determine the direction of the lateral line, and then the feature line is drawn.

[0062] In this embodiment, reading the survey line direction and determining the drawing direction of the feature line based on the survey line direction can accurately determine the direction and position of the feature line, which is beneficial for data processing. Optionally, based on the above technical solutions, reading the survey line direction includes:

[0063] The direction of the measuring line is determined based on the coordinates of the measuring points on the lateral line.

[0064] One method to determine the direction of a survey line by measuring the coordinates of measuring points is to connect the measuring points sequentially and calculate the average slope of the line connecting adjacent measuring points to determine the position and direction of the survey line, or to select two suitable measuring points at the beginning and end and connect them to determine the position and direction of the survey line.

[0065] In this technical solution, reading the direction of the measuring line clarifies the direction of the measuring line, enabling more accurate measurements.

[0066] S130, determine the arrangement direction and number of processing grids based on the drawing direction of the feature lines and the distribution position of the survey lines.

[0067] The arrangement direction can be horizontal or vertical. The number of arrangements can be determined by the smallest positive integer ratio of the horizontal distribution range of the survey line to the grid width.

[0068] The horizontal direction can be perpendicular to the survey line or the direction of the grid width. The vertical direction can be along the survey line or the direction of the grid length.

[0069] This includes determining the orientation and number of grid cells to be processed.

[0070] The arrangement direction and number of grid lines can be automatically generated by determining the feature lines;

[0071] Alternatively, after determining the feature lines, draw buttons in the first and / or second directions of the feature lines, and determine the grid arrangement direction and number by clicking the buttons.

[0072] The first direction and the second direction can be the directions on both sides of the feature line laterally.

[0073] Based on the above technical solutions, optionally, the arrangement direction and number of processing grids are determined according to the drawing direction of the feature lines and the distribution position of the survey lines, including:

[0074] Determine the length and width of the processing grid.

[0075] Read the lateral distribution range of the survey line and determine the ratio of the lateral distribution range to the width of the processing grid.

[0076] Based on the drawing direction of the feature lines and the scale value, the arrangement direction and number of grid cells are determined. The scale value is limited to 1 and can be less than or equal to 1 or greater than 1. If the scale value is less than or equal to 1, a single column or row of grid cells is generated; if the scale value is greater than 1, a grid of columns or rows with the smallest positive integer value of the scale value is generated.

[0077] This technical solution clarifies the grid arrangement direction and number based on the drawing direction of the feature lines and the ratio of the horizontal distribution range to the width of the processing grid, which helps to simplify the grid.

[0078] Based on the above technical solutions, optionally, if the feature line is a survey boundary line, then the arrangement direction and number of processing grids are determined according to the drawing direction of the feature line and the scale value, including:

[0079] If the ratio is less than or equal to 1, the arrangement width of the processing grid is determined to be 1, and a processing grid with an arrangement width of 1 is generated with the boundary line of the survey line as the reference line.

[0080] If the ratio value is greater than 1, then the arrangement width of the processing grid is determined to be the smallest positive integer greater than the ratio value, and a processing grid with an arrangement width of the smallest positive integer is generated with the survey line boundary line as the reference line.

[0081] The arrangement width can be the smallest positive integer representing the ratio of the transverse distribution range of the survey line to the grid width. For example, when the ratio of the transverse distribution range of the survey line to the grid width is 0.2, the arrangement width is 1; when the ratio of the transverse distribution range of the survey line to the grid width is 6.2, the arrangement width is 7.

[0082] This technical solution determines the number of grid lines for the survey line by drawing boundary lines, avoiding grid intersections and clarifying the grid arrangement direction and number, thereby simplifying the grid.

[0083] Based on the above technical solutions, optionally, if the feature line is the center line of the survey line, then the arrangement direction and number of the processing grids are determined according to the drawing direction of the feature line and the scale value, including:

[0084] If the ratio is less than or equal to 1, the arrangement width of the processing grid is determined to be 1, and a processing grid with an arrangement width of 1 is generated with the center line of the survey line as the axis.

[0085] If the ratio value is greater than 1, then the arrangement width of the processing grid is determined to be the smallest positive integer greater than the ratio value, and a processing grid with an arrangement width of the smallest positive integer is generated with the survey line centerline as the axis.

[0086] This technical solution determines the number of grid lines for the survey line by drawing a center line, avoiding grid intersections and clarifying the grid arrangement direction and number, thus simplifying the grid. Based on the above technical solutions, optionally, after reading the survey line direction and determining the drawing direction of the feature lines according to the survey line direction, the method may further include:

[0087] The survey line and the feature line are displayed on the front-end page; and drawing buttons are generated in the first and second directions of the feature line.

[0088] In response to a click operation of the drawing button in the first or second direction, a processing grid with a width of 1 is generated in the first or second direction of the feature line with the feature line as the boundary.

[0089] In this technical solution, the grid arrangement direction and number are determined by generating drawing buttons, thus simplifying the number of grids.

[0090] S140, the survey line is segmented according to the arrangement direction and number of the processing grid.

[0091] After generating the grid, the radar data is segmented based on the grid. The data in each grid only retains the radar data in the corresponding grid. In this way, when generating the 3D file, only the data in the corresponding grid needs to be read, avoiding wasting time on logic and increasing data processing efficiency exponentially.

[0092] The technical solution of this embodiment draws survey lines based on measurement data of the object under test, reads the direction of the survey lines, determines the drawing direction of feature lines based on the direction of the survey lines, and then determines the arrangement direction and number of processing grids based on the drawing direction of the feature lines and the distribution of the survey lines. Then, the survey lines are segmented according to the arrangement direction and number of processing grids. This solves the problem of the large number of grids determined by coordinates and the time wastage caused by reading radar files for each channel of each survey line. It can clearly define the direction of the survey lines and simplify the number of grids, thereby improving the efficiency of data processing.
