[0002] A river-related construction project refers to a construction project within the management scope of a river or lake. Bridge, wharf, road, ford, pipeline, cable, water intake, drainage, and other construction projects that are built across, through, or adjacent to a river or lake within the management scope of a river or lake should comply with flood control standards, shoreline planning, navigation requirements, and other technical requirements, and should not endanger the safety of dikes, affect the stability of river regimes, or hinder flood drainage. The construction unit should submit the engineering construction plan to the water administrative department with jurisdiction (such as the Ministry of Water Resources, the river basin management agency, or the local water conservancy bureau) in accordance with the law, obtain the flood control evaluation review opinion and the river-related construction project license, and then implement it. If the engineering construction plan has not been reviewed and agreed by the relevant water administrative department in accordance with the aforementioned flood control requirements, the construction unit may not start construction. The river-related construction project license makes provisions for the type and scope of the project. After the project is approved, the construction and operation of the project need to be supervised, and the traditional supervision method is on-site inspection. With the rapid development of the economy and society, there are more and more river-related construction projects, and the workload of water administrative supervision is increasing.

[0057] In the following, example embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, and not all embodiments of the present application, and it should be understood that the present application is not limited by the example embodiments described herein.

[0058] Figure 1 Fig. 1 illustrates an optional flow diagram of a river-related construction project approval compliance evaluation method according to an embodiment of the present application; as Figure 1As shown, the river-related construction project approval construction conformity evaluation method according to the embodiment of the present application comprises:

[0059] S102, obtaining the license space range data of the river-related construction project, wherein the license space range data comprises the construction project type data and the space range data of the river-related construction project;

[0060] S104, obtaining the graph spot of the construction site; the graph spot is the remote sensing image interpretation graph spot data of the construction site of the river-related construction project;

[0061] S106, after the coordinate system unification processing of the graph spot and the license space range data, based on the spatial position information in the graph spot, the candidate license set associated with the graph spot is filtered out from the license space range data through spatial retrieval;

[0062] S108, calculating the spatial relationship between the graph spot and each license in the candidate license set, generating the associated license set, and respectively calculating the type conformity, the position conformity and the area conformity between the graph spot and the license for the type of each license in the associated license set;

[0063] S110, according to the preset weight, the type conformity, the position conformity and the area conformity are weighted and summed to generate the conformity weighted score of each license, and all the conformity weighted scores of the associated license set are traversed, and the highest score is determined as the final approval construction conformity evaluation result of the graph spot.

[0064] Next, a wharf construction project is taken as an example to illustrate the present application. The license information of the wharf comprises the type "wharf" and the allowed construction range is a two-dimensional polygon region. The graph spot data of the actual construction of the wharf is obtained through satellite remote sensing image interpretation, and the type of the graph spot is also "wharf", and the spatial position information thereof is composed of a series of coordinate points to form an irregular two-dimensional polygon.

[0065] Firstly, the license space range data of the wharf construction project is obtained, wherein the construction project type data is "wharf", and the space range data is a two-dimensional polygon coordinate set representing the allowed construction region. Meanwhile, the graph spot of the construction site is obtained, i.e. the image data of the actual construction of the wharf obtained through remote sensing image interpretation. The coordinate system unification processing is performed on the graph spot and the license space range data to convert them to the same coordinate system.

[0066] Then, based on the spatial position information in the graph spot, the candidate license set associated with the graph spot is filtered out from the license space range data through spatial retrieval. For example, assuming that there are multiple license items, the licenses possibly associated with the graph spot are filtered out to form the candidate license set by calculating the spatial relationship between the graph spot and each license. The type compliance degree, position compliance degree and area compliance degree of the graph spot and the license are calculated respectively for the type of each license in the associated license set.

[0067] In this embodiment, for the graph spot S, there is one license range L in the associated license set, and the type of L is "wharf". The type compliance degree is If there is another license , and the type of the license is "channel regulation", if "channel regulation" contains wharf, the type partial compatibility coefficient may be set according to the business rules, and then the type compliance degree is 0.6.

[0068] In the formula, for the calculation of the position compliance degree, the centroids CS and CL of the graph spot S and the license range L are calculated first, for example, the distance between the centroid of the graph spot and the centroid of the license range is meters, the maximum distance between any point on the license range and the centroid of the license range is meters, and the attenuation coefficient is . The formula is . For the area compliance degree, assuming that the area of the graph spot is 8000 square meters, the area of the license range is 10000 square meters, the intersection area of the graph spot and the license range is 7500 square meters, and the difference set area is 500 square meters, then . The preset weights are, for example, , , respectively, and the compliance degree weighted score is . All compliance degree weighted scores of the associated license set are traversed, and assuming that 0.863 is the highest score, the final batch construction compliance degree evaluation result of the graph spot is determined as 0.863, and the river-related construction project batch construction compliance degree evaluation is completed.

[0069] Based on the content of the above embodiment, as an optional embodiment, the river-related construction project batch construction compliance degree evaluation based on the spatial position information in the graph spot, the candidate license set associated with the graph spot is filtered out from the license space range data through spatial retrieval, which comprises: calculating the minimum circumscribed rectangle of the graph spot based on the spatial position information in the graph spot; and performing spatial intersection operation on the minimum circumscribed rectangle and the license space range data set to obtain the intersected candidate license set.

[0070] In this embodiment, the minimum circumscribed rectangle of the graph spot is calculated based on the spatial position information in the graph spot. Figure 2Fig. 2 shows a schematic diagram of a minimum circumscribed rectangle of a plot according to an embodiment of the present application, as shown in Figure 2 As shown, the plot is an irregular polygon, and its minimum circumscribed rectangle is obtained by geometric calculation, which can completely contain the plot and has the minimum area. Then, the minimum circumscribed rectangle is subjected to a spatial intersection operation with the licensed space range dataset to obtain the intersection candidate license set. For example, assuming that there are 100 licenses, 10 licenses intersecting with the minimum circumscribed rectangle of the plot are selected as the candidate license set by performing the intersection operation between the minimum circumscribed rectangle of the plot and the spatial range of each license, so that the subsequent detailed spatial relationship calculation only needs to be performed on the 10 licenses, greatly improving the efficiency.

[0071] Based on the above embodiment, as an optional embodiment, the present application provides a method for evaluating the construction project license compliance degree, which comprises the following steps of: calculating the spatial relationship between the plot and each license in the candidate license set, and determining the license spatial range data with the spatial relationship of intersection as the associated license to obtain the associated license set.

[0072] Figure 3 Fig. 3 shows a schematic diagram of the intersection between the plot circumscribed rectangle and the license range according to an embodiment of the present application, as shown in Figure 3 As shown, in the present embodiment, the spatial relationship between the plot and each license in the candidate license set is calculated, and it is judged whether they intersect. The license intersecting with the plot is determined as the associated license to generate the associated license set. For example, for each license in the candidate license set, the spatial relationship between the plot and the license is judged by a spatial analysis algorithm. If the spatial relationship between the plot and the license L is intersection, the license L is included in the associated license set, and finally the associated license set is obtained to further calculate the compliance degree.

[0073] Based on the above embodiment, as an optional embodiment, in the evaluation of the river-related construction project license compliance degree, if the plot type and the license type are completely matched, such as the plot type being “wharf” and the license type also being “wharf”, the type compliance degree is 1. If the plot type and the license type are partially incompatible, for example, the plot type is “road” and the license type is “wharf”, the type compliance degree is 0. If the plot type and the license type are partially compatible, for example, the license type is “channel regulation” which contains various sub-projects such as wharf and revetment, and the plot type is “wharf”, the type partial compatibility coefficient a can be set to 0.6, and the type compliance degree is 0.6.

[0074] Optionally, whether the plot S is a building type belonging to the range of the license L type is judged by using the following mathematical formula for quantification:

[0075]

[0076] Wherein, a is a type part compatibility coefficient, defined according to business rules, and the default value is 0.6.

[0077] Based on the content of the above embodiment, as an optional embodiment, the application provides a method for obtaining the position compliance in the evaluation of the river-related construction project approval compliance, comprising the following steps:

[0078] Obtaining the Euclidean distance between the centroid of the graph and the centroid of the permitted range and the maximum distance between any point on the permitted range and the centroid of the permitted range;

[0079] Determining the position compliance according to the Euclidean distance of the centroid of the permitted range and the maximum distance between any point on the permitted range and the centroid of the permitted range;

[0080] The specific determination method of the position compliance is as follows:

[0081]

[0082] Wherein, is the graph, is the permitted range, is the maximum distance between any point on the permitted range L and the centroid of the permitted range L, , is the attenuation coefficient (a>0), which controls the distance sensitivity, is the basic attenuation, is suitable for punitive severe attenuation. In this embodiment, a frame diagram for calculating the centroid distance between the graph and the permitted range according to an optional embodiment of the application is shown, as shown in

[0083] the position compliance is analyzed by determining the position relationship between the graph and its associated permit. Including distance, position relationship, etc. Figure 4 Figure 4 The calculation of the position compliance adopts different methods according to the spatial data form of the permit.

[0084] For example, form 1:

[0085] For example, form 1:

[0086] ​When the permitted spatial data is in the form of a single point, that is, a permitted point, only a rough calculation of its positional conformity can be made. The position of the permitted point (a single point) relative to the patch can be one of three types: 1. The permitted point is inside the patch edge, and the conformity is determined to be a preset value of 1; 2. The permitted point is on the patch edge, and the conformity is determined to be a preset value of 2; 3. The permitted point is outside the patch edge, and the conformity is determined to be 0.

[0087] Form 2:

[0088] When the permitted spatial data is in the form of a polygon, i.e., within the permitted area, a more accurate calculation of its positional compliance can be made, including the calculation of its distance compliance. Specifically:

[0089] The input conditions for both the patch and the permitted area are two-dimensional spatial data. Calculate the Euclidean distance between their centroids. Figure 5 The figure illustrates a schematic diagram of a frame representing the maximum distance between any point on the permitted range L and the centroid, according to an optional embodiment of this application. Figure 5 As shown, calculate the area of ​​the polygonal surface of the patch S and the polygonal surface of the permitted range L, respectively, for the vertices of the polygons. Its area is:

[0090]

[0091] Calculate the centroids CS and CL of the polygonal features S and the polygonal features within the permissible range L, respectively. The formula for calculating the centroid is:

[0092]

[0093]

[0094] Calculate the Euclidean distance between the centroids of the polygonal features S and the polygonal features within the permissible range L (where n is the spatial data dimension, taken as 2):

[0099] Calculate the positional compliance:

[0100]

[0101] wherein , is a decay coefficient (0 > >0), controlling the distance sensitivity. is a base decay, is applicable to a punitive sharp decay.

[0102] Physical meaning: the closer the distance, the higher the score (tending to 1); the farther the distance, the lower the score (tending to 0).

[0103] Based on the content of the above embodiment, as an optional embodiment, the application provides an obtaining step of the area compliance in the evaluation of the river-related construction project approval compliance, comprising:

[0104] calculating the intersection area and the difference set area of the graph and the permitted range;

[0107]

[0108] wherein, is a graph, is a permitted range, is an intersection area, is a difference set area, is an area calculation formula, is an intersection area, is a difference set area

[0109] In this embodiment, Figure 6 a frame schematic diagram of the difference set calculation and the intersection calculation of the graph and the permitted range according to an optional embodiment of the application is shown, as shown in Figure 6 , the area coverage of the graph S in the permitted L range is quantitatively evaluated to calculate the proportion of the intersection and difference set area in the total area of the permitted L range. Wherein, the graph and the permit are not empty.

[0110] For example, the part of the face-shaped polygon of the graph S that coincides with the face-shaped polygon of the permitted range L is defined as the intersection area ,

[0111]

[0112] For example, the difference set area is defined as The region S, a polygonal area in the image, is independent of the permissible range polygon L; that is, the region in S that does not overlap with L.

[0113]

[0114] The specific method for determining the area is as follows:

[0115]

[0116] Then calculate the area compliance:

[0118] in, For the purpose of the image, Within the scope of the license, The intersection area For the difference set region, Here is the formula for calculating the area. The area of ​​intersection. The area of ​​the difference set. The area within the permitted range.

[0119] Finally, the type conformity, location conformity, and area conformity are weighted and summed according to preset weights to generate a conformity weighted score for each permit. All conformity weighted scores of the associated permit set are traversed, and the highest score is determined as the final approval conformity evaluation result of the map patch.

[0120] In this embodiment, a weighted score for compliance is calculated based on the weight of each compliance degree.

[0121]

[0123] ;

[0124] End of license set After traversal, the highest weighted score of compliance is taken as the permissible compliance score of the current patch, for example, as shown in the following formula:
