Description

Technical Field

[0001] The present invention belongs to the field of garden landscape, and in particular relates to a construction method, device and application of complex garden shapes based on AR reality enhancement. Background Art

[0002] As people's requirements for the quality of landscape architecture continue to increase, more and more garden designers choose to set up complex shapes in the visual core areas of garden projects.

[0003] For example, flower borders are a form of landscape with flowers and plants as the main elements. Due to the wide variety of plant species and complex contours of flower border landscapes, their implementation also faces many challenges and difficulties. The accuracy of construction layout is crucial to the final construction effect of the flower border. The complex contour lines on the flower border design drawings need to be accurately restored in actual construction. For example, the contour lines of the flower border are tortuous and changeable. In traditional flower border planting projects, construction workers will use lime to "draw" the contour lines of the flower border on the planting soil on site. However, this process is completely dependent on the construction workers' understanding and experience of the drawings, as well as their proficiency in drawing lime lines. Therefore, there are often errors between the contour lines of the design plan and the lime lines laid out on site, making it difficult to guarantee the final landscape effect of the flower border.

[0004] Another example is the special-shaped seat. The construction drawings of the special-shaped seat only include the overall plan drawings and a small number of section drawings. In order to present a natural and smooth shape, the special-shaped seat is composed of a continuous curved surface with a curvature of G1 that changes nonlinearly. It is difficult to accurately describe the special-shaped three-dimensional shape with only a small number of two-dimensional section drawings. The more obvious the nonlinear deformation of the three-dimensional shape, the more vague the expression of the shape in the two-dimensional drawing. After the special-shaped seat is processed in the factory and assembled on site, the construction team should inspect the product quality, including the shape, surface gloss, thickness and other aspects. However, the existing measurement technology can only measure the overall size of the product and the approximate size of a small number of nodes, and cannot truly verify the processing accuracy of the special-shaped product. The accuracy review of special-shaped landscape sketches always stays at the stage of "looking like" and passing. Due to the lack of effective technical means for accuracy review, the construction team cannot accurately control the actual amount of work, and it is difficult to ensure the production accuracy and installation accuracy of special-shaped landscape sketches.

[0005] Therefore, this solution is proposed to address the shortcomings of garden landscapes with complex shapes that are difficult to accurately lay out and difficult to review and test after construction. Summary of the invention

[0006] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a method, device and application for constructing complex garden shapes based on AR reality enhancement, which can realize the construction layout or model review and detection of complex shape construction objects through AR reality enhancement technology to ensure construction quality.

[0007] Technical solution: To achieve the above purpose, the technical solution of the present invention is as follows:

[0009] Construct 3D models of complex garden shapes and 3D models of positioning reference objects;

[0010] Extracting the outer contour line of the three-dimensional model of the complex garden shape, and enlarging the outer contour line in proportion to the actual construction size;

[0011] The adjusted outer contour line is projected onto the construction site by using AR augmented reality technology in combination with a positioning reference object;

[0012] The projected outer contour line is used as a reference line for construction; before the construction of the complex garden shape, the reference line is used to perform layout on the construction site to obtain the actual construction layout line, or after the construction of the complex garden shape, the construction object is checked for accuracy according to the reference line.

[0013] Furthermore, it includes synchronously loading the three-dimensional model for positioning reference objects into the three-dimensional model of the construction object to be constructed; and using the positioning reference objects on site to position and control the relative position of the outer contour line and the positioning reference objects.

[0014] Furthermore, the reference line includes reference line one and reference line two. The outer contour line of the three-dimensional model of the object to be constructed is extracted as reference line one, and the outer contour line of the three-dimensional model of the positioning reference object is extracted to form reference line two, and the reference line one and reference line two are integrated into the same layer interface.

[0015] Further, when the reference line is used as a construction layout line, the reference line is widened to form a strip shape.

[0016] Furthermore, before the construction of the complex garden shape, the layout includes: at the construction site, performing multi-point distributed marking on the reference line or forming a continuous marking line.

[0017] Furthermore, after the complex garden shape is constructed, the accuracy review test includes: comparing the reference line with the outer contour of the construction body for coincidence or deviation.

[0018] Furthermore, the positioning reference object is any object existing in the construction site.

[0019] Furthermore, the positioning reference objects include at least one or more of road sidelines, trees, stumps, lamp posts, sculptures, pavilions, and rivers on site.

[0020] A construction device for complex garden shapes based on AR reality enhancement, comprising:

[0021] An image capture and recognition module is used to capture images in a real environment, obtain images of reference objects, or locate objects based on reference objects;

[0023] A virtual content generation module, used for generating corresponding virtual reference lines according to the obtained outer contour lines;

[0024] The projection display module is used to project the generated reference lines into the real environment to achieve an interactive experience.

[0025] The application of AR reality enhancement in the layout of garden landscape contour lines includes a construction method of complex garden shapes based on AR reality enhancement, which is used to layout on the construction site according to the reference line to obtain the actual construction layout line, or project the reference line onto the constructed building body to perform external contour accuracy verification and detection.

The specific technical application process is contour modeling → positioning reference modeling → AR augmented reality layout. After adopting AR technology, the layout of the flower border has changed from "copying" to "tracing", which can greatly improve the accuracy of the layout work. At the same time, by adopting this method, the reference line is projected onto the constructed construction body for external contour matching and accuracy verification, and the model appearance detection and measurement of the constructed landscape model can be performed to ensure the accuracy of the construction.

[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The terms used in the present disclosure are for the purpose of describing specific embodiments only and are not intended to limit the present disclosure. The singular forms "a", "said" and "the" used in the present disclosure and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0035] The specific implementation of the present invention is further described in detail below in conjunction with the drawings and examples.

[0036] As attached Figure 1 As shown, a construction method for complex garden shapes based on AR reality enhancement includes:

[0037] Construct a three-dimensional model of a complex garden shape and a three-dimensional model of a positioning reference object; extract the outer contour line of the three-dimensional model of the complex garden shape, and enlarge the outer contour line in proportion to the actual 1:1 construction size; project the adjusted outer contour line onto the construction site through AR augmented reality technology in combination with the positioning reference object; use the projected outer contour line as a reference line for construction; before the construction of the complex garden shape, perform lofting on the construction site according to the reference line to obtain the actual construction lofting line, or after the construction of the complex garden shape, perform accuracy review and inspection on the construction object according to the reference line.

[0038] The present invention applies AR technology to the layout construction link of complex landscape flower borders, which can help the construction team to accurately control the contour lines during the layout process, ensure that the position and layout of the plants meet the design requirements, and better meet the needs of landscape designers and owners for high-quality flower borders. The specific technical application process is flower border contour modeling → positioning reference modeling → AR augmented reality layout. The outer contour line of the three-dimensional model can be obtained through the image capture and recognition module, or it can be directly modeled in the three-dimensional software to extract the outer contour line of the three-dimensional model, and the outer contour line is enlarged 1:1 in proportion to the actual construction size; the adjusted outer contour line is projected to the construction site through AR reality enhancement technology, and a 1:1 contour projection line can be seen at the construction site; the projected outer contour line is used as a reference line for construction.

[0039] After obtaining the reference line, it is used to perform layout on the construction site according to the reference line to obtain the actual construction layout line, as shown in the attached figure. Figure 3 and attached Figure 4 As shown in , the projected reference line can be directly obtained at the construction site, and the reference line can be used as a layout line or a construction reference line. The reference line is projected onto the construction body that is being constructed or has been constructed to perform outer contour matching and comparison, that is, accuracy verification and inspection.

[0040] It is understandable that the three-dimensional model of the positioning reference object in this solution can be "empty" or "ground". For example, when the flower mirror is built on an open ground, there is no need for a relative reference object, and the ground can also be regarded as a reference object.

[0041] After adopting AR technology, Chuantong's flower border layout has changed from "copying" to "tracing", which can greatly improve the accuracy of the layout work. At the same time, by using this method, the reference line is projected on the built main body for external contour matching and comparison, and the appearance of the built landscape model can be inspected and measured to ensure the accuracy of the construction.

[0042] The three-dimensional model used for positioning the reference object is synchronously loaded into the three-dimensional model of the object to be constructed; the relative position of the outer contour line and the positioning reference object is controlled by using the positioning reference object.

[0043] The positioning reference object is any object existing in the construction site. The positioning reference object includes but is not limited to at least one or more of the road sidelines, trees, stumps, lamp posts, sculptures, pavilions, and rivers at the construction site.

[0044] In some specific implementations, the flower border landscape is known for its smallness and exquisiteness, and the area occupied by a single area is usually small. In the actual construction process, the flower border of a single area can be controlled by the surrounding significant surface construction objects (such as building boundaries, road corners, sculptures or landscape stone centers) to control the relative position. Therefore, it is necessary to establish these surface construction objects that can be used for flower border positioning control, that is, positioning reference objects, and load them into the flower border contour model simultaneously. Using the positioning reference objects, the flower border contour can be accurately placed at the designated position of the design.

[0045] In some specific embodiments, as shown in the attached Figure 3 and attached Figure 4 As shown, the reference line includes reference line 1 C and reference line 2 A1. The outer contour line of the three-dimensional model of the object to be constructed is extracted as reference line 1 C, and the outer contour line of the three-dimensional model of the positioning reference object is extracted to form reference line 2 A1. The reference line 1 C and reference line 2 A1 are integrated into the same layer interface in the modeling software and are also located in the same coordinate system. When projecting to the construction site, the reference line 2 is used to align or overlap with the reference object on the site to form a positioning point, thereby quickly locating the position of the reference line C.

[0046] It can be understood that the three-dimensional model of the positioning reference object in this solution can be "empty" or "ground". For example, when the flower mirror is built on an open ground, there is no need for a relative reference object, and the ground can also be regarded as a reference object. In this case, reference line 2 is the ground line.

[0047] In some specific embodiments, when the reference line is used as a construction layout line, the reference line is widened to form a strip shape. The widened width is in the range of 1 cm to 30 cm. The application of AR technology to project the slender flower border contour lines onto the planting soil needs to be carried out under outdoor strong light construction conditions. The slender contour lines cannot be clearly displayed on the planting soil. Therefore, it is necessary to first import the flower border contour lines drawn by the designer into the three-dimensional model software, pick up the contour lines and offset them to both sides, and build a strip-shaped three-dimensional model block. According to practical experience, the contour lines need to be widened to 10 centimeters wide to ensure smooth implementation.

[0048] In some specific implementations, the lofting includes: at the construction site, performing multi-point distributed marking on the reference line or forming a continuous marking line. That is, the formed reference line can be a continuous line or a dot matrix distribution method, as long as the contour marking can be achieved. Preferably, a continuous curve is used, because the contour line is mostly a G1 continuous curve, and the continuous curve can make the edge contour size more accurate.

[0049] In some specific implementations, the accuracy verification test includes: comparing the reference line with the outer contour of the construction object for coincidence or deviation. During the construction process, the reference line can be used as a reference mark visible to the naked eye, so that the complex structural parts can be constructed according to the reference line to ensure that their appearance is consistent with the expected contour; after construction, the reference line can also be used to perform an outer contour test to confirm whether the outer contour of the constructed object is qualified and whether it can meet expectations based on the coincidence.

[0050] As attached Figure 2 As shown, a construction device for complex garden shapes based on AR reality enhancement includes:

[0051] An image capture and recognition module is used to capture images in a real environment, obtain images of reference objects, or locate objects based on reference objects;

[0052] A three-dimensional model building module is used to build a three-dimensional model and extract the outer contour line of the three-dimensional model;

[0053] A virtual content generation module, used for generating corresponding virtual reference lines according to the obtained outer contour lines;

[0054] The projection display module is used to project the generated reference lines into the real environment to achieve an interactive experience.

[0055] Furthermore, this solution provides the application of AR reality enhancement in the contour line setting of garden landscapes, including the construction method of complex garden shapes based on AR reality enhancement, which is used to perform setting out on the construction site according to the reference line to obtain the actual construction setting out line, or project the reference line onto the construction body under construction or already constructed to conduct the outer contour accuracy verification test. During the construction process, the reference line can be used as a reference mark visible to the naked eye, so that the complex structural parts to be constructed can be constructed according to the reference line to ensure that their appearance is consistent with the expected contour; after construction, the reference line can also be used to perform outer contour detection to confirm whether the outer contour of the constructed construction object is qualified according to the degree of overlap and whether the construction accuracy can meet expectations.

[0056] AR technology not only helps to improve the accuracy and efficiency of construction, but also greatly reduces construction errors and construction costs, demonstrating its great innovation and practical value in garden engineering, and playing a significant role in promoting the construction of garden engineering. The innovative application of AR technology effectively solves many problems in traditional construction methods and injects new vitality and potential into the development of garden engineering. In the future, with the continuous advancement and popularization of AR technology, its application in garden engineering will surely become more extensive and in-depth, further promoting garden engineering to move towards intelligence, environmental protection and sustainable development. I believe that the progress of these digital technologies will bring a better prospect for garden engineering and improve the overall industry level.

[0057] During the layout process, the 3D model of the flower border outline and the positioning reference 3D model are converted into skp format and stored in the iPad; then, the SketchUP 3D software APP in the iPad is run to turn on the AR augmented reality function. The virtual image of the 3D model is projected on the planting soil after the terrain is adjusted. After using AR technology, Chuantong's flower border layout has changed from "copying" to "tracing", which can greatly improve the accuracy of the layout work.

[0058] Embodiment 1:

[0059] As attached Figure 3 and attached Figure 5 As shown, it is the application of flower mirror in garden landscape. Figure 5 In the figure, the left picture is a schematic diagram of the reference line projection; the right picture is a schematic diagram of the construction layout line.

[0060] Among them, A is the reference object; A1 is the reference line 2; C is the reference line 1.

[0061] Construct a three-dimensional model of a complex garden shape and a three-dimensional model of a positioning reference object; extract the outer contour line of the three-dimensional model of the complex garden shape, and enlarge the outer contour line in proportion to the actual 1:1 construction size; project the adjusted outer contour line onto the construction site through AR augmented reality technology in combination with the positioning reference object; use the projected outer contour line as a reference line for construction; before constructing the complex garden shape, perform lofting on the construction site according to the reference line to obtain the actual construction lofting line.

[0062] Flower border landscape is known for its smallness and exquisiteness, and the area occupied by a single area is usually small. In the actual construction process, the relative position of the flower border in a single area can be controlled by the surrounding significant surface construction objects (such as building boundaries, road corners, sculptures or landscape stone centers). Therefore, it is necessary to establish the three-dimensional models of these surface construction objects that can be used for flower border positioning control and load them into the flower border contour model simultaneously. Using the positioning reference three-dimensional model, the flower border contour can be accurately placed at the designated position of the design. First, convert the flower border contour line three-dimensional model and the positioning reference three-dimensional model into skp format and save them in iPad; then, run the SketchUP three-dimensional software APP in iPad, turn on the AR augmented reality function, and project the virtual image of the three-dimensional model on the planting soil after the terrain adjustment; secondly, after confirming the positioning reference construction object, fix the position of the flower border contour line; finally, the construction personnel hold the iPad and use the traditional lime method to perform ground lofting according to the flower border contour line projected on the ground. After adopting AR technology, the flower border lofting of Chuantong has changed from "copying and drawing" to "tracing in red", which can greatly improve the accuracy of the lofting work.

[0063] Embodiment 2:

[0064] As attached Figure 4 and attached Figure 6 The following is an application of corridor seats in garden landscape. Figure 6 In the middle, the right picture shows the main body of the building after construction, and the left picture shows the reference line projected onto the main body of the building for accuracy verification and model matching comparison.

[0065] Among them, A is the reference object; C1 is the reference line 1; and F is the entity of the construction object.

[0066] In the construction process of conventional landscape projects, like ordinary outdoor seats, the construction drawings of special-shaped seats only include overall plan drawings and a small number of cross-sectional drawings. In order to present a natural and smooth shape, the entire special-shaped seat is composed of a nonlinear continuous surface with a curvature of G1. It is difficult to accurately describe the special-shaped three-dimensional shape with only a small number of two-dimensional cross-sectional drawings. The more obvious the nonlinear deformation of the three-dimensional shape, the more vague the expression of the shape in the two-dimensional drawing.

[0067] After the special-shaped benches are processed in the factory and assembled on site, the construction team should inspect the product quality, including the shape, surface gloss, thickness and other aspects. However, the existing measurement technology can only measure the overall size of the product and the approximate size of a small number of nodes, and cannot truly verify the processing accuracy of special-shaped products. The accuracy review of special-shaped landscape sketches always remains at the stage of "passing if it looks like it". Due to the lack of effective technical means for accuracy review, the construction team cannot accurately control the actual amount of work, and it is difficult to ensure the production accuracy and installation accuracy of special-shaped landscape sketches.

[0068] The use of AR technology in the precision review of special-shaped landscape pieces helps to achieve accurate processing and fine installation of special-shaped benches. The design team, construction team and processing manufacturer jointly added a 3D in-depth model as a transition between the 2D drawings and the 3D objects, optimizing the construction process into three stages: in-depth modeling (from 2D drawings to 3D models), processing and installation, and AR augmented reality review (from 3D models to 3D objects).

[0069] In this embodiment, a three-dimensional model of a complex garden shape and a three-dimensional model of a positioning reference object are constructed; the outer contour line of the three-dimensional model of the complex garden shape is extracted, and the outer contour line is enlarged in proportion to the actual 1:1 construction size; the adjusted outer contour line is projected onto the construction site through AR augmented reality technology in combination with the positioning reference object; the projected outer contour line is used as a reference line for construction; after the complex garden shape is constructed, the construction object is subjected to precision review and inspection according to the reference line. After construction, the outer contour can also be inspected through the reference line to confirm whether the outer contour of the constructed object is qualified and whether it can meet expectations based on the degree of overlap.

[0070] (1) Deepening modeling

[0071] The modeling accuracy of the special-shaped stool depends entirely on whether the special-shaped mold conforms to the design drawings. The in-depth designer of the processing plant and the technical staff of the construction unit work together to establish a three-dimensional in-depth model based on the two-dimensional construction drawings of the special-shaped stool. At present, the more mature three-dimensional modeling software that has been used are SketchUP, 3DMAX and Rhino. Among them, Rhino can establish fine, elastic and complex NURBS surface models, which are widely used in three-dimensional animation production, industrial manufacturing, scientific research and other fields. NURBS surface is a surface based on mathematical formulas, which can reflect the continuous and smooth real surface of special-shaped sketches, so the three-dimensional in-depth model of the special-shaped stool is generally established by Rhino. After the three-dimensional model is confirmed by the design team, the processing plant can continue to make the processing mold of the special-shaped seat. At this time, the basis for processing and installation has actually been converted from the two-dimensional construction drawings to the three-dimensional in-depth model. In order to facilitate mold making, the in-depth designer of the processing manufacturer will divide the complete three-dimensional in-depth model of the special-shaped stool into multiple independent small modules and digitally encode them. This method not only improves the production accuracy, but also greatly simplifies the construction process.

[0072] (2) Processing and installation

[0073] The processing manufacturer makes and produces molds according to the independent small modules split from the three-dimensional deepening model. The production process can be divided into four steps: first, make the external processing mold of the special-shaped bench; second, pour the evenly mixed polymer inorganic composite stone material into the mold; third, after the composite material solidifies, remove the mold to obtain the finished product; finally, make detailed adjustments to the finished product, and mark the digital code of each small module in a hidden position. At the construction site, build the concrete foundation of the special-shaped bench according to the construction drawings. After the hardness of the foundation meets the requirements, accurately lay out the bottom edge of the bench, and mark the code of each small module of the special-shaped bench in advance. The processed small modules are transported to the construction site and accurately fixed to the concrete foundation with expansion bolts.

[0074] (3) AR Augmented Reality Review

[0075] The technicians of the construction unit used AR technology to review the accuracy of the finished products of the special-shaped stools, which was divided into three steps: first, the in-depth 3D model of the special-shaped stool was converted into skp format and stored in the iPad; second, the SketchUP 3D software APP in the iPad was run to turn on the AR augmented reality function; finally, the virtual image of the 3D model was projected on the ground. It is worth noting that the 3D model needs to be set at a ratio of 1:1 before projection. During the projection process, the position of the bottom of the model needs to be adjusted to fit the actual product after installation. If it is found that there is a large difference between the virtual image of the 3D model and the actual product, a screenshot is taken and sent to the processing manufacturer, requiring re-production on the grounds that the product accuracy is too low. If the difference is not large, it can be regarded as the processing accuracy meets the standard, and the 3D model can be installed to review the engineering quantity. Through this method, the production accuracy and installation quality of the special-shaped stools can be effectively ensured.

[0076] Through the successful practice in the two construction application scenarios of precise layout of complex landscape flower borders and precision review of special-shaped landscape sketches, it can be seen that AR technology not only helps to improve the accuracy and efficiency of construction, but also greatly reduces construction errors and construction costs, showing its great innovation and practical value in garden engineering, and playing a significant role in promoting the construction of garden engineering. The innovative application of AR technology effectively solves many problems in traditional construction methods and injects new vitality and potential into the development of garden engineering. In the future, with the continuous advancement and popularization of AR technology, its application in garden engineering will surely be more extensive and in-depth, further promoting garden engineering to move towards intelligence, environmental protection and sustainable development. I believe that the progress of these digital technologies will bring a better prospect for garden engineering and improve the overall industry level.
