Description

Technical Field

[0001] The present invention relates to the technical field of road garden design, and in particular to a garden design and correction method combined with road condition change detection. Background Art

[0002] Most of the existing road landscapes adopt extensive artificial design methods. After the road construction is completed, the road greening scheme suitable for the road type or road side space type is determined through artificial site survey. However, there are many types of roads, such as two-way four-lane roads, two-way two-lane roads, bridges, or tunnels, etc., and different road greening schemes are usually adopted. Similarly, the types of road side spaces are also diverse. For example, when the road type is an elevated road in the city, the road side space type is mostly buildings such as high-rise buildings, while when it is an elevated road in the suburbs, the road side space type may be open areas such as farmland and rivers. The greening schemes for roads with different road side space types are usually different. When the road type and road side space type constitute different combinations, the road greening scheme is even more diverse.

[0003] Road type and road side space type are the main factors affecting road greening schemes. Due to the variety of road types, there are also many types of road side spaces. Therefore, the design of road greening schemes currently basically adopts the manual design method after manual on-site survey. This method has the lag of greening scheme design, and it is necessary to wait until the basic construction of the road is completed before entering the design stage. In addition, with the acceleration of urban construction, some sections of the entire road may need to be modified, such as changing the road type, such as changing from two lanes to four lanes, changing a section or several sections of the road from a ground road to an elevated road, bridge, underground tunnel, etc. At this time, it may be necessary to adjust the greening scheme of these road sections or other road sections adjacent to these road sections. The existing method also adopts the method of manually adjusting the greening scheme after manual on-site survey, and it is impossible to automatically issue a revised plan based on the original greening plan of the entire road.

[0004] In addition, the most critical thing is that the existing greening plans that are artificially designed or modified through on-site surveys have no physical samples. The greening plans designed in the software after on-site surveys are only presented on the screen. The final greening effect can only be seen after the greening planting is completed on-site according to the plan. The purchaser cannot see the same or similar physical samples as the greening plan in a real environment before the greening construction. Summary of the invention

[0005] The present invention aims to automatically output road greening plans with physical samples for newly built roads or planned road sections without on-site surveys, only by inputting road singularity parameters, thereby reducing the lag in greening plan design and revision and improving the degree of automation in design and revision. It provides a garden design and revision method combined with road condition change detection.

[0006] To achieve this object, the present invention adopts the following technical solutions: A garden design and correction method combined with road condition change detection is provided, comprising the steps of: L1, input or input singular point parameters of the road to be designed and corrected after completing the road condition change detection, including the coordinates of the road type mutation point and / or the road side space type change point, wherein the mutation point is bound to the first road type and the second road type where the road type mutation occurs, and the change point is bound to the first road side space type and the second road side space type where the road side space type changes, and the first road side space type and the second road side space type are associated with the same or different road types; L2, using the singular point parameters as matching conditions, matching a designed revised road with similarity to the road to be designed and revised from a road library with a physical sample or a road library with a physical sample that has completed dynamic greening plan updates, and adding it to the reference road set; L3, according to the reference road set, marking the roads to be designed and revised by zoning; L4, for the road sections in the to-be-designed and revised road with the same partition and / or revised partition marks, assign the regionalized garden design or revision plan bound to the same partition mark and / or the revised partition mark; and prompt the user to manually revise the garden plan for the road sections in the to-be-designed and revised road marked as manually revised, and then add the to-be-designed and revised road with the completed greening plan design or revision to the road library.

[0007] Preferably, in step L2, the method for matching the reference road set of the road to be designed and corrected comprises the steps of: A1, performing parameter value similarity matching on each first singular point in the road to be designed and corrected and each second singular point in the same road to be designed and corrected, and extracting the second singular point with a similarity greater than a similarity threshold and a maximum similarity to associate with the first singular point as a matching object; A2, judging whether the difference between a first number of the first singular points in the to-be-designed corrected road and a second number of the second singular points associated with the points in the designed corrected road to implement step A1 is greater than a preset difference threshold, and whether the ratio of the second number to a third number of the second singular points in the designed corrected road is greater than a preset ratio threshold, If yes, it is determined that the designed revised road has similarity with the to-be-designed revised road; If not, it is determined that the designed revised road has no similarity with the revised road to be designed.

[0008] Preferably, the first singular point and the second singular point include the mutation point and / or the change point.

[0009] Preferably, the method for dynamically updating the greening scheme of the designed revised road comprises the steps of: C1, inputting the coordinates of the road section to be constructed in the designed revised road; C2, the system extracts each singular point covered by the road segment according to the input road segment coordinates of the road segment to be constructed; C3, updating the singular point parameters of each of the extracted singular points according to the road type and / or road side space type to be constructed for the road segment; C4, in the reference road set associated with the designed revised road to be constructed, matching the partition revised reference road having the maximum sorting order similarity and the maximum singular point parameter value similarity with each singular point updated in step C3; C5, constructing the two singular points forming the road segment to be constructed into a corresponding third point set, then matching a fourth point set having the maximum singular point parameter value similarity with the third point set from the partitioned revised reference road matched in step C4, and screening out each of the third point sets that are not matched to the fourth point set and adding them to the artificial revised point set associated with the designed revised road to be constructed; C6, the road segments associated with the third point set matched to the fourth point set are corrected using the regionally bound garden design or correction method corresponding to the fourth point set, and the road segments associated with each of the third point sets in the artificial correction point set are prompted to perform artificial garden scheme correction.

[0010] Preferably, in step L3, the method for zoning the road to be designed and corrected comprises the steps of: B1, further matching the referenced designed revised roads having the greatest sorting order similarity with the first singular points in the to-be-designed revised roads from the referenced road set; B2, extracting a singular point sequence consisting of second singular points with the ability to directly assign partitions from the proposed reference road to be designed for correction, and filtering out first singular points having similar point-position association relationships with the second singular points in the singular point sequence from the first singular points formed in the road to be designed for correction, and filtering out the remaining first singular points as the basis points for difference partition correction; B3, correct each difference partition between each point and its adjacent first singular point, and make the same partition mark for the divided area between the adjacent second singular points in the singular point sequence and the proposed divided area between the adjacent first singular points that have a similar point relationship with the two adjacent second singular points, and make the corrected area with a corrected partition mark.

[0011] Preferably, in step B2, the singular point sequence with the ability of direct partition assignment is: a sequence composed of second singular points that are continuously arranged in the reference designed correction road and have been point-associated with the corresponding first singular point in the to-be-designed correction road; the second singular point and the first singular point have been point-associated, which means: the first singular point in the to-be-designed correction road has a singular point parameter value similarity with the second singular point and the maximum similarity, and the first singular point is bound with the corresponding second singular point by a point similarity relationship to complete the association of the two points.

[0012] Preferably, in step B3, the method for correcting each difference partition between each of the reference points and the first adjacent singular points comprises the steps of: B31, matching a partitioned revised reference road having the greatest similarity to the proposed reference designed revised road from the reference road set; B32, obtaining the first singular points adjacent to each of the reference points, and forming a corresponding first point set in pairs, and then matching a second point set having a maximum singular point parameter value similarity with the first point set from the partition correction reference road with each of the first point sets as a unit, and screening out each of the first point sets that are not matched with the second point set and adding them to the artificial correction point set; B33, for the correction area associated with the first point set, a correction partition mark is made to correct the garden design or correction plan carried by the divided area bound to the second point set that has the maximum singular point parameter value similarity with the first point set; and the road area covered between the two first singular points in each of the first point sets in the artificial correction point set is marked with an artificial correction of the greening plan.

[0013] Preferably, the method for matching the partition-corrected reference road comprises the steps of: B311, obtaining the first elevation data bound to each of the second singular points in each of the designed corrected roads in the reference road set, including the first elevation difference between the first divided area and the second divided area adjacent to the second singular point in the same designed corrected road, and then performing a dimensionality increase operation on each of the second singular points in the same designed corrected road and directly connecting adjacent points to obtain a first elevation fitting curve of each of the designed corrected roads in three-dimensional space; and obtaining the second elevation data bound to each of the second singular points in the proposed reference designed revised road, including the second elevation difference between the first divided area and the second divided area adjacent to the second singular point in the same proposed reference designed revised road, and then performing a dimensionality increase operation on each of the second singular points in the same proposed reference designed revised road and directly connecting adjacent points to obtain a second elevation fitting curve of the proposed reference designed revised road in three-dimensional space; B312, matching the designed corrected road corresponding to the first elevation fitting curve having the maximum curve similarity with the second elevation fitting curve from the first elevation fitting curves as the partition correction reference road.

[0014] Preferably, the first elevation difference is: the difference between a first spatial distance in the vertical direction between a first point having the maximum elevation associated with a singular point in a first divided area or a first proposed divided area in the same road and the singular point, and a second spatial distance in the vertical direction between a second point having the maximum elevation associated with the singular point in a second divided area or a second proposed divided area adjacent to the first divided area or the first proposed divided area.

[0015] The present invention has the following beneficial effects: 1. Based on the two main factors that affect the design or modification of road greening plans, namely, road type and / or road side space type, singular points are set in the road, making it possible for the system to automatically realize the design and modification of road greening plans.

[0016] 2. Add the designed revised roads with road greening entity samples to the road library, and use the singular point parameters as matching conditions to match the designed revised roads with similarities to the roads to be designed and revised from the road library and add them to the reference road set. The designed revised roads added to the road library incorporate artificial road greening correction plans, which are bound to the singular points associated with the revised road sections, which is beneficial for the system to match the data accuracy of the reference road set suitable for the roads to be designed and revised from the road library according to the singular point parameters, and further helps to improve the pertinence and accuracy of the design and correction of road greening plans for the designed and revised roads.

[0017] 3. By setting the singular point parameters, it is possible to quickly match a reference road set suitable for the road to be designed and corrected from many designed and corrected roads with physical samples. The user only needs to input the singular point parameters of each singular point in the road to be designed and corrected. The operation is very simple, which lays the foundation for the system to automatically, quickly and specifically provide road greening design or correction plans for the road to be designed and corrected.

[0018] 4. The first singular points with point-to-point correlation are constituted into a first sequence, the second singular points with point-to-point correlation are constituted into a second sequence, and the actual sorting order of the second singular points in the second sequence along the road length direction in the designed corrected road to which they belong is constituted into a third sequence. By calculating the consistency of the sorting order of the second singular points in the second sequence and the third sequence, a simple method is used to achieve rapid and accurate matching of the reference designed corrected road suitable for the road to be designed from the reference road set.

[0019] 5. Through the zoning marking processing of the road to be designed and revised in step L3, based on the marking information of the divided areas, it is possible to quickly find the divided areas with the same zoning relationship as the proposed divided areas in the road to be designed and revised, and the revised areas with the zoning revision relationship in each designed and revised road, which is conducive to improving the speed and accuracy of road greening design and revision of the proposed divided areas.

[0020] 6. In step B31, the elevation data is used as one of the data bases for curve similarity matching, taking into account the influence of the elevation data on the road greening design of different road types and different road side space types under the elevation space conditions in actual situations. Therefore, when the road greening correction is performed on the correction area in the design correction road by using the correction partition in the matched partition correction reference road, it is more targeted.

[0021] 7. Through step L3, based on the referenced designed and revised roads identified from the referenced roads, each road segment in each road to be designed and revised is subjected to the same partition, revised partition and manual revision marking, thereby realizing the direct, revised or manual assignment of the garden design or revision scheme for each road segment. The direct and revised assignment methods are fully automated, and the assigned garden designs or revision schemes all have physical samples, which realizes the rapid and automatic issuance of garden designs or revision schemes with physical samples for the roads to be designed and revised. The manual assignment method increases the diversity of garden designs or revision schemes for each designed and revised road in the road library, which can reversely improve the pertinence of subsequent garden design schemes for other roads to be designed and revised.

[0022] 8. The user only needs to input the parameter values ​​of each singular point in the road to be designed and corrected, and the system can automatically mark the same partitions, corrected partitions, and areas that need manual correction for each road section in the road. For the marked same partitions and corrected partitions, the system will automatically match the appropriate landscaping design or correction plan for the state of the road to be designed and corrected. For the marked artificial correction areas, the system will prompt the user to manually design or correct the garden plan for the corresponding road section. Then the designed or corrected roads are added to the road library to increase the physical templates and improve the pertinence and accuracy of the subsequent automatic issuance of garden design plans for other roads to be designed and corrected.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] The garden design and correction method combined with road condition change detection provided by the embodiment of the present invention is as follows: Figure 1 As shown, the steps include: L1, input or input singular point parameters of the road to be designed and corrected after completing the road condition change detection, including the coordinates of the road type mutation point and / or the road side space type change point, wherein the mutation point is bound to the first road type and the second road type where the road type mutation occurs, the change point is bound to the first road side space type and the second road side space type where the road side space type changes, and the first road side space type and the second road side space type are associated with the same or different road types; For example, suppose Figure 3 If the road to be designed and corrected represented by figure a in FIG is a newly built road or a planned newly built road, the singular point parameters of each singular point of the newly built road are input in step L1. Assuming that the road is a planned road, for example Figure 3 The road between the singular points a5 and a6 in Figure a is a road section that has been completed or is to be constructed, and after construction, the road type or road side space type of this road section changes compared with the adjacent sections, then the singular point parameters of the singular points a5 and / or a6 are input in step L1 (if the road type and / or road side space type between the singular points a5 and a6 changes compared with the road type and / or road side space type between the singular points a4 and a5, then the singular point parameters of the singular point a5 are input).

[0030] Singular points include mutation points that represent a sudden change in road type and / or change points that represent a change in the road side space type. Figure 2 As shown in , road segment 100 is a two-way four-lane road, and road segment 200 is a two-way two-lane road. From road segment 100 to road segment 200, the two-way four-lane road changes to a two-way two-lane road, and a sudden change in road type occurs. The width of the road type sudden change rectangular area can be set to 30 meters, and the length is the width of the lane. For example, the width of the two-way four-lane road is used as an example, and the area selected by the rectangular box is the road type sudden change area (such as Figure 2 As shown in the figure mark "300", the system randomly selects a point in the mutation region 300 (such as Figure 2 The mutation point is bound to the first road type (such as Figure 2 Two-way four-lane road as shown in the figure) and the second road type (such as Figure 2 Two-way two-lane road as shown in ).

[0031] Similarly, assuming Figure 2 As shown in FIG, the left side of the road of the sub-road segment 201 belonging to the road segment 200 is of the B spatial type, and the right side of the road is of the A spatial type; the spatial types of the left side and the right side of the road of the sub-road segment 202 are both of the B spatial type. If the road side spatial type changes between the sub-road segments 201 and 202, the road side spatial type change area (such as Figure 2 As shown in the figure mark "500", the system randomly selects a point in the change area 500 (such as Figure 2 (shown by reference numeral “600” in the figure) is a point where the road side space type changes.

[0032] It should be noted here that there are many existing technical means for detecting road condition changes, such as using visual recognition algorithms to Figure 3 The road segment between the two singular points a5 and a6 shown in the figure is monitored by video. When it is detected that the road segment has a change in road type or road side space type compared with its adjacent road segment, the singular points a5 and a6 are extracted, and the numerical update of the parameters bound to the singular points a5 and a6 is completed. However, in actual applications, it is very costly and unrealistic to perceive the change in road type or road side space type of a road segment through monitoring. Most of the road construction is limited cost construction of a certain section or several sections of road. Therefore, it is preferred to use a manual detection method for road condition change detection, that is, manually input the coordinates of the road segment to be constructed or to be constructed, and then the system extracts the singular points covered by the road segment according to the coordinates of the road segment, and then updates the parameter data of each extracted singular point according to the road type or road side space type to be changed after the completion of the construction.

[0033] Through step L1, after inputting the singular point parameters of the road to be designed and corrected into the system or completing the road condition change detection, such as Figure 1 As shown, the garden design and correction method combined with road condition change detection provided in this embodiment is transferred into steps: L2, using the singular point parameters as matching conditions, from the road library with physical samples or the road library with dynamic greening plan updates and physical samples, the designed revised roads with similarities to the road to be designed are matched and added to the reference road set; The method of matching the reference road set of the road to be designed and corrected in step L2 is specifically described below: The reference road set matching the road to be designed and corrected specifically includes the following steps: A1, for each singular point in the designed and corrected road (defined as the first singular point), perform parameter value similarity matching with each second singular point in the same designed and corrected road, and extract the second singular point with the maximum similarity and a similarity greater than the similarity threshold to associate with the first singular point as the matching object; For example, Figure 3 The singular points a1-a7 in the graph a are the first singular points. Assuming that the road library with a physical sample (i.e., the road greening is completed) or the greening scheme is dynamically updated and has a physical sample includes designed and corrected roads, then for each first singular point in a1-a7, Each second singular point in each of the stripes is matched for parameter value similarity. For example, One of the articles is Figure 3 According to the expression of graph b in , the parameter value similarity matching is performed for each first singular point in a1-a7, such as the singular point a1, and each second singular point in b1-b8 in the designed corrected road expressed in graph b.

[0034] For example, if the singular point a1 and the singular point b2 have similar singular point parameter values ​​and the similarity is the maximum, then the second singular point b2 is extracted and associated with the first singular point a1. It should be noted here that the point association is constructed on the premise that the road to be designed and corrected is one-to-one with the designed and corrected road.

[0035] Here, the method for similarity matching of singular point parameter values ​​is briefly described as follows: In this embodiment, the singularity point includes a mutation point and / or a change point. When the singularity point is both a mutation point and a change point, the singularity parameter value of the singularity point is: the fusion value of the road type mutation value bound to the singularity point and the road side space type change value; when the singularity point is a mutation point or a change point, the singularity parameter value of the singularity point is: the road type mutation value bound to the singularity point or the road side space type change value. The road type mutation value can be determined by the encoding method. The road type of "two-way four lanes" can be encoded as "SX4CD", and the road type of "two-way two lanes" can be encoded as "SX2CD". The road type changes from two-way four lanes to two-way two lanes, which can be expressed in the encoding method as "SX4CDtoSX2CD". The road side space type change value can also be implemented in a similar encoding method. The fusion value of the road type mutation value and the road side space type change value can be directly spliced ​​and fused, for example, the road type mutation value expressed by "SX4CDtoSX2CD" and the road side space type change value expressed by "XXX" bound to the same singular point are fused into a fusion value expressed by "SX4CDtoSX2CD-XXX". For the similarity matching of two singular points, in this embodiment, the coding consistency matching method is adopted. For example, for the two fusion values ​​of "SX4CDtoSX2CD-001" and "SX2CDtoSX4CD-002", the similarity threshold can be set to 1. When "SX4CDtoSX2CD" and "SX2CDtoSX4CD" have coding similarity, the similarity between "SX4CDtoSX2CD" and "SX2CDtoSX4CD" is "1", otherwise it is "0". "SX4CDtoSX2CD" and "SX2CDtoSX4CD" are only different in the change direction from four lanes to two lanes. In this case, the system assumes that the two have similarity, and the similarity value is assigned to "1". However, assuming that "SX4CDtoSX2CD" and "SX6CDtoSX4CD" are matched for similarity, it is obvious that the lane change types represented by the two are different, so the similarity value of the two is assigned to "0". And "001" and "002" are obviously different road side space types, so the similarity of "001" and "002" is assigned to "0". Therefore, the similarity of "SX4CDtoSX2CD-001" and "SX2CDtoSX4CD-002" is 0.5, which does not meet the condition of the similarity threshold greater than or equal to "1", and it is determined that the two are not similar.

[0036] For each designed and corrected road in the road library, after completing the point association of the singular point, in step L2, matching the road to be designed and corrected can refer to the method of the road set and proceed to step: A2, determining whether the difference between a first number of first singular points in the road to be designed for correction and a second number of second singular points associated with the points in the designed road for correction that implement step A1 is less than a preset difference threshold, and whether the ratio of the second number to a third number of second singular points in the designed road for correction is greater than a preset ratio threshold, If so, it is determined that the designed revised road and the to-be-designed revised road have similarity; If not, it is determined that the designed revised road has no similarity with the revised road to be designed.

[0037] For example, Figure 3 The number of the first singular points (defined as the first number) in the road to be designed and corrected expressed by the graph a in is "7", that is, there are 7 first singular points from a1 to a7; Figure 3 The number of second singular points (defined as the second number) in the designed corrected road expressed by the b diagram that realizes the point association of step A1 (i.e., has a singular point parameter value similarity with a first singular point in a1-a7) is assumed to be "5". For example, each of the 5 second singular points b2, b3, b4, b6, and b7 realizes point association with a corresponding first singular point in a1-a7. Then the difference between the first number and the second number is 7-5=2. Assuming that the preset difference threshold is "3", the judgment condition that the difference between the first number and the second number is less than the difference threshold is met. Figure 3 The second singular points in the designed corrected road expressed by the b diagram include b1-b8. The number of second singular points (defined as the third number) is "8", so the ratio of the second number to the third number is five-eighths. Assuming that the ratio threshold is set to "0.5", the judgment condition that the ratio of the second number to the third number is greater than the preset ratio threshold is also met, so it is judged that Figure 3 The designed corrected road expressed in Figure b has similarity with the corrected road to be designed expressed in Figure a.

[0038] The method involved in step L2 for dynamically updating the greening scheme of the designed and revised road with a physical template will be described in detail in the following content. The following first describes the technical content to be performed in step L3 after matching the reference road set in step L2.

[0039] After matching the reference road set in step L2, Figure 1 As shown, the garden design and correction method combined with road condition change detection provided in this embodiment is transferred into steps: L3, based on the reference road set matched in step L2, the road to be designed and revised is marked by partition, which specifically includes the following steps: B1, further matching the referenced designed revised roads having the maximum sorting order similarity with the first singular points in the to-be-designed revised roads from the referenced road set; For example, suppose that the reference road set includes the designed modified roads , , . Assume that the corrected road has been designed Depend on Figure 3 The b diagram in the figure shows that there are 8 singular points in total, including b1-b8 (defined as the second singular point), among which b2 and Figure 3 The first singular point a1 in the road to be designed and corrected, represented by the a figure in , has a similarity point-to-point relationship, and b3 and a2, b4 and a3, b6 and a4, and b7 and a6 also have a similarity point-to-point relationship. Then the system first sorts the first singular points a1, a2, a3, a4, and a6 in the direction of the road length to form a sorting sequence expressed as { a1, a2, a3, a4, a6}, and sorts b2, b3, b4, b6, and b7 according to the point-to-point relationship to form a sorting sequence expressed as { b2, b3, b4, b6, b7}. It should be noted here that the first singular points in { a1, a2, a3, a4, a6} are sorted in the direction of the road length, and the second singular points in { b2, b3, b4, b6, b7} are sorted according to their respective relationships with the corresponding first singular points. Then b2, b3, b4, b6, and b7 are sorted in the direction of the road length. For example, assuming that b3 is arranged before b2 in the direction of road length, and b4, b6, and b7 are arranged in order after b2, then b2, b3, b4, b6, and b7 are arranged in the direction of road length, expressed as {b3, b2, b4, b6, and b7}. Finally, the system calculates the similarity of the sorting order of {b2, b3, b4, b6, and b7} and {b3, b2, b4, b6, and b7}, which is expressed as the ratio of the number of elements with the same sorting order to the total number of elements in the sequence. For example, in these two sequences, the sorting order of b4, b6, and b7 is the same, and the number of elements with the same sorting order is "3", and the total number of elements in the sequence is "5". The similarity of the two sequences is three-fifths, which is the similarity of the sorting order of the designed and corrected roads and the roads to be designed and corrected in the reference road set. In step B1, the system extracts the designed revised road with the greatest sorting order similarity from the reference road set as the matched reference designed revised road.

[0040] After matching the referenced designed roads for the roads to be designed and corrected from the referenced road set in step B1, in step L3, the method of zoning the roads to be designed and corrected is transferred to the steps: B2, extracting a singular point sequence consisting of second singular points with the ability to directly assign partitions from the road to be designed and corrected, and filtering out first singular points with similar point-position correlations with second singular points in the singular point sequence from first singular points formed in the road to be designed and corrected, and filtering out the remaining first singular points as the basis points for difference partition correction; Specifically, the singular point sequence with the ability of direct partition assignment is: a sequence composed of the second singular points that are continuously arranged in the referenced designed correction road and are associated with the corresponding first singular point in the to-be-designed correction road. The second singular point is associated with the first singular point, which means that the first singular point in the to-be-designed correction road has a singular point parameter value similar to the second singular point and has the maximum similarity. The first singular point is bound to the second singular point in a point similarity relationship to complete the association of the two points.

[0041] For example, Figure 3 The second singular points b2, b3, and b4 in the proposed reference road are arranged in a continuous manner and are associated with b2. Figure 3 The first singular point a1 in the road to be designed and corrected expressed in Figure a is associated with b3 as a2, and with b4 as a3. Then the sequence {b2, b3, b4} formed by b2, b3, and b4 is a singular point sequence with the ability of direct partition assignment.

[0042] In step B2, the method of obtaining the point-based correction of the difference partition by filtering is illustrated by the following example: Continuing with the above example, assume that the singular point sequence with partition direct assignment capability is { b2, b3, b4}, Figure 3 The first singular points a1, a2, and a3 in the road to be designed and corrected expressed in the a diagram have similar point correlation relationships with the second singular points b2, b3, and b4 in the singular point sequence, respectively. Then, a1-a3 are filtered out from the first singular points a1-a7 in the road to be designed and corrected, and the remaining first singular points a4-a7 are filtered out as the basis points for difference partition correction.

[0043] After obtaining the points on the road to be designed and corrected as the basis for difference partition correction through filtering in step B2, in step L3, the method for performing partition marking processing on the road to be designed and corrected proceeds to step: B3, correct each difference partition between each point and its adjacent first singular point, and make the same partition mark for the divided area between the adjacent second singular points in the singular point sequence and the proposed divided area between the adjacent first singular points with similar point relationship with the two adjacent second singular points, and make the corrected area with the corrected partition mark.

[0044] For example, in the singular point sequence {b2, b3, b4}, the second singular points b2 and b3 are adjacent, b3 and b4 are adjacent, b2 and b3 have point-similar association relationships with the first singular points a1 and a2 respectively, and b3 and b4 have point-similar association relationships with a2 and a3 respectively. Figure 3 In the example, the proposed subdivision area 10 between adjacent a1 and a2 is marked as the same subdivision area as the already subdivided area 20 between adjacent b2 and b3. The mark carries the point-similar association relationship between a1 and a2 and b2 and b3, and carries the greening design or correction scheme associated with the already subdivided area 20. Subsequently, the greening design and correction scheme associated with the already subdivided area 20 can be quickly obtained based on this mark, and the proposed subdivision area 10 defined as the same subdivision area as the already subdivided area 20 can be found, which is conducive to improving the speed and pertinence of road greening design and correction for the proposed subdivision area.

[0045] The following specifically describes how to correct the difference partitions in the design correction road in step B3: Continuing with the above example, Figure 3 The first singular point a4-a7 in the graph a is the remaining basis point filtered in step B2. In step B3, the road area between the basis point a4 and the adjacent a3 constitutes the first difference partition, the road area between a4 and a5 constitutes the second difference partition, the road area between a5 and a6 constitutes the third difference partition, and the road area between a6 and a7 constitutes the fourth difference partition.

[0046] In this embodiment, the method for correcting the difference partition includes the steps of: B31, matching the partition correction reference road with the maximum similarity to the referenced designed correction road from the reference road set; In this embodiment, two methods are provided to match the partition correction reference road with the greatest similarity to the reference designed correction road from the reference road set.

[0047] The first method is: filter out the referenced designed corrected road matched in step B1 from the referenced road set, and then further match the designed corrected road with the maximum similarity to the referenced designed corrected road from the remaining referenced road set as the matched partitioned corrected reference road. This maximum similarity matching method is the same as the method of matching the referenced designed corrected road from the referenced road set for the road to be designed corrected in step B1, both of which match the maximum sorting order similarity between the first singular point and the second singular point with similar point position association relationship in the two roads, and will not be repeated here.

[0048] The second method adds the elevation data bound to each singular point as the data basis for matching the partition correction reference road. The elevation data in this embodiment refers to: the elevation difference between the first point with the maximum elevation with the singular point in the first divided area of ​​the same road and the second point with the maximum elevation with the singular point in the second divided area adjacent to the first divided area. The elevation refers to the spatial distance between the first point or the second point and the singular point in the vertical direction.

[0049] In this embodiment, the second method for matching partitions to correct reference roads specifically includes the following steps: B311, obtaining first elevation data bound to each second singular point in each designed and revised road in the reference road set, including a first elevation difference between a first divided area and a second divided area adjacent to the second singular point; For example, suppose Figure 3 The elevation difference between the first divided area (indicated by the reference numeral "20") and the second divided area (indicated by the reference numeral "30") adjacent to the second singular point b3 in the designed corrected road expressed in Figure b is 10 meters, that is, the difference between the first spatial distance in the vertical direction between the first point with the maximum elevation and the second singular point b3 in the first divided area 20 and the second spatial distance in the vertical direction between the second point with the maximum elevation and the second singular point b3 in the second divided area 30. There are many existing methods for finding the point with the maximum elevation between the second singular point b3 and the first divided area 20 or the second divided area 30, for example, the z-axis value of the first point in different areas of the first divided area 20 in the three-dimensional space can be randomly selected, and then the z-axis value of the second singular point b3 in the z-axis direction can be obtained, and the maximum value obtained by subtracting the two z-axis values ​​is the first point with the maximum elevation. In the prior art, the vertical height of a singular point or a point randomly selected from a divided area from the ground can be calculated or directly obtained through satellite detection or manual marking.

[0050] After obtaining the first elevation data bound to each second singular point in the same designed and corrected road by calculating the difference between the first spatial distance and the second spatial distance, in step B311, the second singular points in the same road are then subjected to a dimensionality increase operation and directly connected to obtain a first elevation fitting curve of each designed and corrected road in three-dimensional space; For example, Figure 3 Figure b is a plane curve diagram of a designed and corrected road drawn in two-dimensional space without carrying elevation data. When each second singular point in the diagram carries elevation data, the first elevation fitting curve of the plane curve in three-dimensional space is obtained by performing dimensionality enhancement operations on these second singular points (the values ​​of the x and y axes remain unchanged, and the z-axis value is changed from "0" to the corresponding z-axis) and directly connecting each adjacent second singular point.

[0051] Similarly, in step B311, the second elevation data bound to each second singular point in the proposed reference designed corrected road is obtained simultaneously, including the second elevation difference between the first divided area and the second divided area adjacent to the second singular point in the same proposed reference designed corrected road, and then the second singular points in the same proposed reference designed corrected road are upgraded in dimension and the adjacent points are directly connected to obtain the second elevation fitting curve of the proposed reference designed corrected road in three-dimensional space.

[0052] The calculation principle of the second elevation fitting curve is the same as that of the first elevation fitting curve and will not be repeated here.

[0053] After obtaining the first elevation fitting curve and the second elevation fitting curve through step B311, the method of matching the partition correction reference road in step B31 proceeds to step: B312, matching the designed correction road corresponding to the first elevation fitting curve having the maximum curve similarity with the second elevation fitting curve from each first elevation fitting curve as the partition correction reference road.

[0054] It should be noted here that there are many existing methods for curve similarity matching, and since the similarity matching method for the first elevation fitting curve and the second elevation fitting curve is not within the scope of the rights protection required by this application, it will not be explained in detail.

[0055] In step B31, the elevation data is used as one of the data bases for curve similarity matching, taking into account the influence of elevation space conditions on the road greening design of different road types and different road side space types in actual situations, so that the road greening correction of the correction area in the road to be designed and corrected by the corrected partition in the reference road with the matched partition correction is more targeted. Therefore, the method provided in steps B311-B312 can also be applied to step B1. Through steps B311-B312, firstly, the referenced designed and corrected road is matched from the referenced road set, and then from at least one referenced designed and corrected road, the matching method with the maximum sorting order similarity with each first singular point in the road to be designed and corrected is further matched to the referenced designed and corrected road, and then step B2 is executed, so that the matched referenced designed and corrected road is more targeted as the basis for garden design and correction of the road to be designed and corrected.

[0056] After matching the partition correction reference road through step B31, in step B3, the method of correcting each difference partition between each reference point and its adjacent first singular point includes the following steps: B32, obtaining the first singular points adjacent to each reference point, and each pair of points constitutes a corresponding first point set, and then using each first point set as a unit, matching a second point set having the maximum singular point parameter value similarity with the first point set from the partition correction reference road, and filtering out the first point set that is not matched with the second point set and adding it to the artificial correction point set; For example, Figure 3 The first singular points a4-a7 in the road to be designed and corrected, represented by a in FIG, are the remaining reference points after filtering through step B2. According to the formation rule of the first point set defined in step B32, the first singular points a3 and a4 constitute the first point set s1, the first singular points a4 and a5 constitute the first point set s2, the first singular points a5 and a6 constitute the first point set s3, and the first singular points a6 and a7 constitute the first point set s4.

[0057] In this embodiment, the method of matching the second point set having the maximum singular point parameter value similarity with the first point set from the partition-corrected reference road is exemplified as follows: Assumptions Figure 3 The b figure in FIG. 1 is the partition correction reference road matched in step B31. The system constructs a corresponding second point set for each two adjacent second singular points in the partition correction reference road. Figure 3 The partition correction expressed in the b graph in the reference road is constructed from the second singular points b1 and b2 as the second point set r1, b2 and b3 as the second point set r2, and so on, until b7 and b8 are constructed as the second point set r7. Then, taking the maximum singular point parameter value similarity matching of the first point set s1 and each second point set as an example, the first point set s1 is matched with the second point sets r1-r7 one by one for singular point parameter value similarity. For example, the first singular points a3 and a4 in the first point set s1 are matched with the second singular point b1 in the second point set r1 for singular point parameter value similarity. If a3 matches b1, a4 is matched with the second singular point b2. If they also match, it is determined that the first point set s1 and the second point set r1 have singular point parameter value similarity. If any first singular point in the first point set s1 does not match any second singular point in the second point set r1, it is determined that the first point set s1 and the second point set r1 do not have singular point parameter value similarity. Then, the second point set with the maximum singular point parameter value similarity is extracted from all second point sets that have similarity with the first point set.

[0058] It should be noted here that the basis data for matching the singular point parameter value similarity between the first point set and the second point set includes any one or more of the road type mutation value bound to the singular point, the road side space type change value and the elevation difference.

[0059] After obtaining the second point set having the singular point parameter value similarity with the first point set through step B32 and obtaining the artificially corrected point set, in step B3, the method of correcting each difference partition between each point and its adjacent first singular point is transferred to step: B33, for the correction area associated with the first point set, a correction partition mark is made to correct the garden design or correction plan carried by the divided area bound by the second point set with the maximum singular point parameter value similarity with the first point set; and the road area covered between the two first singular points in each first point set in the artificial correction point set is marked with an artificial correction of the greening plan.

[0060] For example, suppose Figure 3 The area 40 between the first singular points a4 and a5 in the first point set in the graph a is the correction area. In step B33, the correction area 40 is modified by a second point set (assuming that Figure 3 The divided area (assuming that Figure 3 The area indicated by reference numeral "50" in Figure b) carries a revised zoning mark for revision of the garden design or revision plan.

[0061] Through step L3, after the road to be designed and revised is marked by zoning, Figure 1 As shown, the garden design and correction method combined with road condition change detection provided in this embodiment is transferred into steps: L4, for the road sections with the same zoning and / or revised zoning marks in the road to be designed and revised, assign the divided garden design or revision scheme bound to the same zoning mark and / or revised zoning mark; and prompt the user to manually revise the garden scheme for the road sections marked as manually revised in the road to be designed and revised, and then add the roads to be designed and revised that have completed the greening scheme design or revision to the road library.

[0062] The following is an explanation of the method for dynamically updating the greening plan for the designed and revised road involved in step L2, which specifically includes the following steps: C1, input the coordinates of the road section to be constructed in the designed revised road; for example, assuming Figure 3Figure a in FIG. 1 is a designed revised road to be constructed on a certain section or several road sections. Assuming that the road section 60 in the road section is the road section to be constructed, the coordinates of the road section 60 in the road are input in step C1. In this embodiment, for each road section in the road after the singular point parameter value similarity matching is completed and the partitioning process is performed, the corresponding position coordinates can be assigned according to the extension direction of the road. There are many existing methods for assigning position coordinates to road sections. For example, any point in the road section selected by the rectangular frame can be positioned, and the positioning position coordinates of the point are used as the position coordinates assigned to the area.

[0063] C2, the system extracts the singular points covered by the road segment according to the input road segment coordinates of the road segment to be constructed; for example, following the example in step C1, the road segment 60 covers the first singular points a6 and a7, then the first singular points a6 and a7 are extracted in step C2; C3, updating the singular point parameters of each extracted singular point according to the road type and / or road side space type to be constructed for the road segment; Continuing with the above example, for example, if the road type to be constructed for road segment 60 is changed from two-way four-lane to two-way two-lane, the singular point parameters bound to the first singular points a6 and a7 extracted in step C2 are updated; the calculation method of the singular point parameters has been described in detail in the above content and will not be repeated here.

[0064] C4, in the reference road set associated with the designed revised road to be constructed, matching the partition revised reference road having the maximum sorting order similarity and the maximum singular point parameter value similarity with each singular point updated in step C3; For example, suppose Figure 3 Figure a in the figure is a designed and revised road to be built, and one of the designed and revised roads in its associated reference road set (how to obtain the reference road set associated with the road to be designed or revised is explained in detail in steps A1-A2, which will not be repeated here) is as follows Figure 3 Example of Figure b in Figure 3 Match the image b in Figure 3 The method of determining that each first singular point in the graph a has a second singular point with the largest singular point parameter value similarity has been explained in the above content and will not be repeated here. In addition, the method of determining whether two roads have the largest singular point sorting order similarity based on each singular point with the singular point parameter value similarity in the two roads has also been clearly explained in the above content and will not be repeated here.

[0065] C5, construct the third point set for the two singular points that form the road section to be constructed. For example, continuing with the above example, Figure 3The first singular points a6 and a7 forming the road segment 60 in the figure a are constructed as a corresponding third point set; then, a fourth point set having the maximum singular point parameter value similarity with the third point set is matched from the partition correction reference road matched in step C4, and each third point set that is not matched to the fourth point set is screened out and added to the artificial correction point set associated with the designed correction road to be constructed; the method for judging whether the third point set and the fourth point set have the maximum singular point parameter value similarity is the same as the method for judging whether the first point set and the second point set have the maximum singular point parameter value similarity in step B32, and will not be repeated.

[0066] C6, for the road segments associated with the third point set matched to the fourth point set, the garden design or correction scheme corresponding to the fourth point set is used for correction, and the road segments associated with each third point set in the artificial correction point set are prompted to correct the artificial garden scheme.

[0067] In summary, the garden design and correction method combined with road condition change detection provided by this embodiment requires that the user only needs to input the parameter values ​​of each singular point in the road to be designed and corrected, and the system can automatically mark the same partitions, correction partitions, and areas that need manual correction for each road segment in the road. For the marked same partitions and correction partitions, the system will automatically match a suitable and physical model of landscaping design or correction scheme for the state of the road to be designed and corrected. For the marked artificial correction area, the system will prompt the user to manually design or correct the garden scheme for the corresponding road segment. Then, the designed or corrected road is added to the road library to increase the amount of road library data with physical samples, and improve the pertinence and accuracy of the subsequent automatic issuance of garden design schemes for other roads to be designed and corrected.

Those skilled in the art should understand that various modifications, equivalent substitutions, changes, etc. can be made to the present invention. However, as long as these changes do not deviate from the spirit of the present invention, they should be within the scope of protection of the present invention.
