Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of garden construction, and particularly relates to a garden Taihu stone solitary peak shape automatic generation method and system. BACKGROUND

[0002] The Taihu stone solitary peak is an important component in garden construction, and the Taihu stone is often used as the stone material for the rockery in the garden. The good Taihu stone is used as the solitary peak to enrich the landscape appreciation of the garden. Before the rockery technology matures, most of the gardens in history are constructed by using the Taihu stone solitary peak as an important way. There are a large number of articles and paintings in history to record the appreciation of the strange stone, and the "thin, wrinkled and transparent" are summarized to describe and appreciate the stone peak. However, most of the Taihu stone solitary peaks left in history are artificially processed and carved, and the naturally formed ones are few. With the continuous advancement of park construction, the demand for stone materials for rockery construction is increasing, and therefore the private courtyard tends to use the solitary peak to enrich the landscape. However, the natural thin and leaky state of the stone material is gradually scarce.

[0003] At present, the reference of the solitary peak shape has two aspects, one is to refer to the solitary peak shape left in history, and the other is to refer to the shape of the solitary peak depicted in the historical paintings. Both of these two methods have the defect that the reference cases are too few to meet the broad aesthetic needs. At the same time, due to the thinking rigidity of the craftsmen during processing, the diversity of the solitary peak shape is limited, resulting in the processing mode of the Taihu stone solitary peak in the market, which is characteristicless and causes the solitary peak in the private courtyard to be the same. Therefore, there is an urgent need for a solitary peak shape automatic generation method to guide the craftsmen to process the ordinary lake stone into a solitary peak to enrich the construction of the garden. SUMMARY

[0004] In view of the deficiencies of the prior art, the purpose of the present application is to provide a garden Taihu stone solitary peak shape automatic generation method and system to solve the problems in the background art.

[0005] The purpose of the present application can be achieved by the following technical solutions:

[0006] A garden Taihu stone solitary peak shape automatic generation method, comprising the following steps:

[0007] Step 1, first collect the three-dimensional shape data of the Taihu stone solitary peak in the existing garden and the image data of the Taihu stone solitary peak in the historical paintings, obtain the shape database and attribute database of the Taihu stone solitary peak, and derive the parameters for controlling the shape and attributes;

[0008] Step 2, measure the size of the lake stone raw material to be processed, select the state of the Taihu stone solitary peak as a standing peak or a lying peak, and then import the size of the lake stone raw material into a computer 3D modeling software to obtain a virtual processing model;

[0009] Step 3, compare the virtual machining model in step 2 with the morphology database in step 1, input the morphology control points and path control points, and generate the initial morphology of the unique peak in accordance with the size of the lake stone raw material;

[0010] Step 4, according to the parameter sample of the attribute database in step 2, input the three control parameter values of the three control parameters "thin", "wrinkle" and "transparent" for controlling the surface texture of the lake stone into the initial morphology of the unique peak obtained in step 3, optimize the unique peak modeling of the initial morphology, and generate the final lake stone unique peak morphology;

[0011] Step 5, input the lake stone unique peak model data adjusted in step 4 into the 3D printing numerical control machine, print and output the unique peak morphology entity model, and then the craftsman refers to the printed entity model to carve the lake stone raw material.

[0012] Preferably, the number of morphology control points and path control points is an integer between 1 and 50, the higher the number of morphology control points and path control points set, the more the volume of the lake stone raw material is eliminated, the lower the number of morphology control points and path control points set, the less the volume of the lake stone raw material is eliminated, and when the number of morphology control points and path control points is 1, the lake stone raw material is eliminated by 50% of the volume.

[0013] Preferably, the "thin" control parameter in step 4 is a parameter control of the thinness, the "wrinkle" control parameter is a parameter control of the wrinkle degree, and the "transparent" control parameter is a parameter control of the hole number, and the range of the thinness, the range of the wrinkle degree and the range of the hole number are all between 1 and 10.

[0014] Preferably, the greater the thinness, the more the volume of the lake stone raw material is eliminated and thinned, when the thinness is 10, 50% of the volume of the lake stone raw material based on the initial morphology obtained in step 3 is eliminated and thinned in width and length, and when the thinness is 1, the initial morphology of the lake stone raw material obtained in step 3 is maintained.

[0015] Preferably, the greater the wrinkle degree, the more the area of the lake stone raw material texture wrinkle is increased, when the wrinkle degree is 10, 50% of the surface area of the lake stone raw material based on the initial morphology obtained in step 3 is increased, and when the wrinkle degree is 1, the initial morphology of the lake stone raw material obtained in step 3 is maintained.

[0016] Preferably, the greater the hole number, the more the holes of the lake stone raw material are randomly opened, when the hole number is 10, 50% of the surface area of the lake stone raw material based on the initial morphology obtained in step 3 is used to randomly open holes, and when the hole number is 1, the initial morphology of the lake stone raw material obtained in step 3 is maintained.

[0019] 2.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1 As shown, a method for automatically generating the unique peak shape of Taihu stones in gardens includes the following steps:

[0031] Step 1: First, collect the three-dimensional morphological data of Taihu stone peaks in existing gardens and the image data of Taihu stone peaks in historical paintings to obtain the morphological database and attribute database of Taihu stone peaks, and obtain the various parameters that control their morphology and attributes.

[0032] The detailed process of step 1 is as follows:

[0033] Step 1.1: First, use a 3D scanner with a scanning accuracy of 0.1mm to perform 3D data scanning on the existing Taihu stone peaks in the garden. Then, use photogrammetric scanning technology to collect images of Taihu stone peaks from historical paintings.

[0034] Step 1.2: Then, data collection and comparison are carried out to form a morphological database and obtain morphological patterns related to the size of lake stones. For example, standing peaks and single peaks are usually larger at the top and smaller at the bottom, while lying peaks and single peaks are usually smaller at the top and larger at the bottom.

[0035] Step 1.3: Finally, use the morphological database to collect and compare data to form an attribute database, and obtain the texture patterns related to the surface of the lake stone, such as the degree of thinness, the degree of wrinkles, and the number and size of holes.

[0036] Step 2: Measure the size of the Taihu stone raw material to be processed, select the single peak state of Taihu stone as either upright or horizontal, and then import the size of the Taihu stone raw material into computer 3D modeling software to obtain a virtual processing model;

[0037] The detailed process of step 2 is as follows:

[0038] Step 2.1: Obtain the three-dimensional dimensions of the lake stone raw material by measurement. Lake stone raw materials are usually not very flat. When measuring the dimensions, record the dimensions according to the widest, longest, and highest values ​​of the raw material.

[0039] Step 2.2, import the measured three-dimensional size data of the lake stone raw material into a computer 3D modeling software, such as Rhinoceros, 3DS MAX, Creo, CATIA, etc.

[0040] Step 3, compare the virtual machining model in step 2 with the morphology database in step 1, input the morphology control points and path control points, and generate the initial shape of the unique peak that conforms to the size of the lake stone raw material;

[0041] The detailed process of step 3 is as follows:

[0042] Step 3.1, select the database data of related size in the morphology database in step 1 as reference, summarize the basic morphology rule, and set the position and number of the morphology control points and the position and number of the path control points in the three-dimensional model of the lake stone raw material, such as Figure 2 Figure 3 As shown in the figure, the round dot is the morphology control point, and the square dot is the path control point;

[0043] Step 3.2, set the morphology control points to form a growth path with bionics characteristics through 3D modeling software and visual compilation platform such as Physarealm in Grasshopper, and then let the software grow to form a spatial morphology;

[0044] Step 3.3, according to the density and spatial position of the growth path in step 3.2, optimize through automatic geometric topology, and finally obtain the initial shape of the unique peak of the lake stone,

[0045] Wherein, the morphology database model referred to according to different lake stone raw material sizes will also be different, the position of the set morphology control points is determined according to the morphology database referred to, and the number thereof can be more or less, the value interval of the morphology control points and the path control points is 1-50, the higher the number of the set morphology control points and path control points, the more complex the initial shape, and the more the volume of the lake stone raw material is eliminated, the less the number of the set morphology control points and path control points, the simpler the initial shape, and the less the volume of the lake stone raw material is eliminated, when the value is 1, it is the largest to eliminate 50% of the volume of the original lake stone size.

[0046] Step 4, according to the parameter samples of the attribute database in step 2, input the three control parameter values of the lake stone surface texture in the unique peak initial shape obtained in step 3, the three control parameters are "thin", "wrinkle" and "transparent" control parameters, optimize the unique peak modeling of the initial shape, and generate the final lake stone unique peak shape;

[0047] The "thin" control parameter is a parameter control of the thinness degree. According to the thinness degree and the law of the thinness degree in the attribute database parameter sample, the thinness degree of the lake stone is controlled by a numerical value. The maximum value of the thinness degree is 10, which can eliminate and thin 50% of the size of the initial shape obtained in step 3 in width and length. When the minimum value of the thinness degree is 1, the initial shape obtained in step 3 is basically maintained. According to the demand, the thinness degree can be adjusted in the numerical value interval of 1-10 to obtain the required thinness degree.

[0048] The "wrinkle" control parameter is a parameter control of the wrinkle degree. According to the wrinkle degree of the surface texture of the lake stone in the attribute database parameter sample, the wrinkle degree of the lake stone is controlled by a numerical value. The maximum value of the wrinkle degree is 10, which can increase the texture wrinkle area by 50% on the surface of the initial shape obtained in step 3. When the minimum value of the wrinkle degree is 1, the initial shape obtained in step 3 is basically maintained. According to the demand, the wrinkle degree can be adjusted in the numerical value interval of 1-10 to obtain the required wrinkle degree.

[0049] The "transparency" control parameter is a parameter control of the number of holes. According to the number and size of the holes in the attribute database parameter sample, the number of holes of the lake stone is controlled by a numerical value. The maximum value of the number of holes is 10, which is 50% of the surface area of the initial shape obtained in step 3 for randomly opening holes. When the minimum value of the number of holes is 1, the initial shape obtained in step 3 is basically maintained. According to the demand, the number of holes can be adjusted in the numerical value interval of 1-10 to obtain the required number of holes.

[0050] The shape law and parameter control in steps 3 and 4 and the texture law and parameter control are as shown in Tables 1 and 2.
