Description
Technical Field
[0001] The present invention relates to the technical field of mathematical models, and in particular to a method, device, equipment and readable storage medium for calculating earthwork volume. Background Art
[0002] With the advancement of science and technology and the improvement of people's requirements for quality of life, the scale and number of various engineering projects are constantly increasing. The proportion of earthwork volume in engineering investment is often large. The calculation of earthwork volume is an important factor in determining the engineering cost estimate and scheme selection. Therefore, calculating the accurate earthwork volume is of great significance to engineering projects.
[0003] The purpose of calculating earthwork volume is to obtain the volume difference of surface materials. The cross-section method used in traditional engineering cannot accurately calculate the excavation volume of anchor foundation pits. At the same time, in actual engineering measurements, whether using the cross-section method or the grid method, the workload is very large, and once the starting edge of the cross-section or grid is selected, it is difficult to reflect the true characteristics of the terrain, so there is often a large discrepancy between the calculated earthwork volume and the actual earthwork volume.
[0004] Moreover, due to the wide range of soil in the geographical environment, the complexity of the terrain structure, the diversity of geographical factors and other factors, the difficulty and accuracy of earthwork calculation in engineering projects are jointly determined. Therefore, how to quickly and accurately calculate the earthwork volume, especially the earthwork volume calculation for large areas and complex terrain, is of great significance for reasonably arranging project progress, accurately calculating project costs, and improving the quality of public projects.

[0043] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.
[0044] It should be noted that references to "one embodiment," "an embodiment," "an example embodiment," etc., in this specification indicate that the described embodiment may include specific features, structures, or characteristics. However, not every embodiment must include these specific features, structures, or characteristics. In addition, such references do not necessarily refer to the same embodiment. Furthermore, when specific features, structures, or characteristics are described in conjunction with an embodiment, whether or not explicitly described, it is indicated that it is within the knowledge of those skilled in the art to incorporate such features, structures, or characteristics into other embodiments.
[0045] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0046] In some embodiments, as Figure 1 As shown in FIG, a method for calculating earthwork volume is provided, and the specific method includes:
[0047] S101, obtaining actual three-dimensional coordinate data of a target area and designed three-dimensional coordinate data of the target area.
[0048] Among them, the target area is the area where earthwork volume calculation is required. For example, when constructing a bridge, the construction location is the target area; the actual three-dimensional coordinate data is the three-dimensional coordinate data of each position in the target area before construction; the design three-dimensional coordinate data is the three-dimensional coordinate data of each point in the target area after construction according to the design drawing.
[0049] Specifically, the actual three-dimensional coordinate data of the target area can be collected based on instruments such as a total station, GPS, and laser rangefinder, and then the manually uploaded design three-dimensional coordinate data can be obtained.
[0050] Optionally, the method of obtaining actual three-dimensional coordinate data and design three-dimensional coordinate data can also be: obtaining data collection requirements of the target area; data collection parameters include feature point collection density, geographical characteristics of the target area and data collection possibility; based on the data collection requirements, collecting actual three-dimensional coordinate data of the target area; obtaining design drawings of the target area and design requirements of the target area; based on the design drawings and design requirements, calculating the design three-dimensional coordinate data of the target area.
[0051] Among them, the feature point collection density is the distance between feature points, which is usually 20 meters. However, for some special terrains, this distance can be appropriately reduced; the geographical characteristics of the target area include the geometric characteristics of the terrain surface, the complexity of the terrain, and the landform type; the data collection possibility is the collection possibility given by the relevant collection instrument; the design requirements include the dynamic requirements of the target area. For example, a large bridge will produce a certain amount of displacement during use, and a certain amount of space must be reserved for these displacements.
[0052] For example, the sampling density of feature points can be determined according to the geographical characteristics of the target area. However, when there are various fault lines such as mountain top points, valley points, foot points, ridge points, saddle points, depressions, ridge lines, valley lines, steep slopes and water edges, that is, places where the terrain changes dramatically, the sampling density of feature points can be increased, and turning points or inflection points must be feature point collection points; when the terrain is relatively fragmented or crisscrossed with gullies, the sampling density of feature points also needs to be increased. When the landform type is mountainous, the sampling density of feature points should also be increased. On the contrary, when the target area is relatively flat, the density of feature point collection can be appropriately reduced. This not only enables the constructed actual triangulated network model to completely restore the actual situation of the target area, but also minimizes the actual three-dimensional coordinate data collection. The workload is reduced. At this time, GPS-RTK technology is used to collect data according to the sampling density of characteristic sampling points. Only when there is only one fixed solution for a point, the actual three-dimensional coordinate data of the point is collected, thereby completing the actual three-dimensional coordinate data collection of the target area; then, according to the design drawings of the target area and the design requirements of the target area, the design three-dimensional coordinate data of the target area is calculated. For example, when the project in the target area is the construction of a bridge, since the bridge will undergo a certain displacement under actual circumstances, it is necessary to consider the changes in the slope ratio of the foundation pit slope, the changes in the width of the reserved platform, the changes in the height of the slope at all levels, the changes in mileage, the changes in offset, etc. On this basis, the design three-dimensional coordinate data of the target area is calculated.
[0053] S102: constructing an actual triangulated network model of the target area according to the actual three-dimensional coordinate data of the target area.
[0054] Specifically, the actual three-dimensional coordinate data of the target area is converted into the form of coordinates (X, Y, Z), and saved in .dat format. The actual three-dimensional coordinate data in .dat format is then imported into CASS software to establish the actual triangulated network model of the target area.
[0055] S103: constructing a design triangulated network model of the target area according to the design three-dimensional coordinate data of the target area.
[0056] Specifically, for the same reason, the design three-dimensional coordinate data of the target area is converted into the form of coordinates (X, Y, Z), and saved in .dat format. Then, the design three-dimensional coordinate data in .dat format is imported into CASS software to establish the design triangulated network model of the target area.
[0057] S104: Calculate the earthwork volume of the target area based on the actual triangulated network model and the designed triangulated network model.
[0058] Specifically, the actual triangulated network model and the designed triangulated network model are superimposed and placed together. The part of the actual triangulated network model that exceeds the designed triangulated network model is the part that needs to be excavated, that is, the excavation volume; the part of the designed triangulated network model that exceeds the actual triangulated network model is the part that needs to be filled, that is, the filling volume.
[0059] Optionally, the method for calculating the earthwork volume of the target area can also be: superimposing the actual triangulated network model and the designed triangulated network model to obtain the model intersection surface between the actual triangulated network model and the designed triangulated network model; and calculating the earthwork volume of the target area based on the actual triangulated network model, the designed triangulated network model and the model intersection surface.
[0060] Specifically, image data of the target area is obtained and the actual triangulated network model is optimized based on the image data; the actual triangulated network model and the design triangulated network model are placed in the same world coordinate system to obtain the model intersection surface between the actual triangulated network model and the design triangulated network model; if the model intersection surface coincides with the outer surface of the actual triangulated network model, the fill volume of the target area is calculated based on the actual triangulated network model and the design triangulated network model; if the model intersection surface coincides with the outer surface of the design triangulated network model, the excavation volume of the target area is calculated based on the actual triangulated network model and the design triangulated network model.
[0061] For example, in the process of establishing the actual triangulated network model, there may be places where the actual triangulated network model does not conform to the actual situation. The camera can be used to capture image data of the target area, and the actual triangulated network model can be optimized based on the image data, such as deleting some 3D feature points, deleting triangles, adding triangles, reorganizing triangles, etc. After optimization, it can be made more consistent with the original landform. After adjustment, an actual triangulated network model that can more intuitively reflect the three-dimensional shape of the original ground can be formed; then the actual triangulated network model and the designed triangulated network model are placed in the same world coordinate system. Since the actual triangulated network model and the designed triangulated network model are not completely consistent, The two are the same, so there will be a model intersection surface between the two. It may be that the actual triangulation model exceeds the design triangulation model, or the design triangulation model exceeds the actual triangulation model. When the actual triangulation model exceeds the design triangulation model, the model intersection surface will coincide with the outer surface of the design triangulation model. At this time, it means that the part exceeding the design triangulation model is the part that needs to be excavated, and this part is the excavation volume; when the design triangulation model exceeds the actual triangulation model, the model intersection surface will coincide with the actual triangulation model. At this time, it means that the part exceeding the actual triangulation model is the part that needs to be filled, and this part is the filling volume.
[0062] The earthwork volume calculation method provided in the above embodiment first obtains the actual three-dimensional coordinate data of the target area and the designed three-dimensional coordinate data of the target area; then constructs an actual triangulated network model of the target area based on the actual three-dimensional coordinate data of the target area; then constructs a designed triangulated network model of the target area based on the designed three-dimensional coordinate data of the target area; and finally calculates the earthwork volume of the target area based on the actual triangulated network model and the designed triangulated network model. By constructing an actual triangulated network model that can reflect the actual situation of the target area and a designed triangulated network model that can reflect the situation of the target area after construction, the difference between the two at various locations can be more clearly distinguished, and the earthwork volume of the two at various locations can be more accurately calculated. This not only increases the accuracy of the earthwork volume calculation, but also does not require a large amount of manual surveying, increasing the convenience of earthwork volume calculation.
[0063] In order to more comprehensively demonstrate this solution, this embodiment provides an optional method for calculating the earthwork volume, such as Figure 2 As shown:

[0065] Among them, data collection parameters include the density of feature point collection, the geographical characteristics of the target area, and the possibility of data collection;

[0074] The earthwork volume includes the excavation volume and the filling volume.
[0075] Specifically, if the model intersection surface coincides with the outer surface of the actual triangulated mesh model, the fill volume of the target area is calculated based on the actual triangulated mesh model and the designed triangulated mesh model; if the model intersection surface coincides with the outer surface of the designed triangulated mesh model, the excavation volume of the target area is calculated based on the actual triangulated mesh model and the designed triangulated mesh model.
