All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the invention provides a power distribution network 10kV pole-mounted load switch 3D model, and the core principle of the invention is to collect two-dimensional images of each structural unit of a load switch through different shooting directions, draw a linear block diagram of each image, select a preset surface grid for converting the two-dimensional images into a stereo diagram, stretch the linear block diagram along a direction parallel to the shooting angle to generate stereo diagrams of different angles, fuse the stereo diagrams of different angles of each structural unit to form a stereo three-dimensional diagram of the unit, and finally combine the stereo three-dimensional diagrams of each structural unit to form the whole load switch 3D model.
That is, the invention firstly generates the three-dimensional stereo map of each structural unit of the load switch, and finally combines the three-dimensional stereo maps of each structural unit together to form the whole 3D model of the load switch, so that the invention not only can display the whole structure diagram of the load switch in an all-round way, but also can help users to understand the internal shapes and structures of complex parts and assemblies of the load switch, enrich the practical forms and diversity of teaching, fully mobilize the learning functions of perception, kinesthesis and thinking of students, arouse the interest of the students in autonomous learning, and greatly improve the training effect.
The simulation system comprises a multi-source data acquisition system 1, a single 3D processing system 2, a 3D integration system 3 and a data storage system 4, the simulation system can develop a virtual three-dimensional model based on an eDrawings program, and the whole simulation process of the three-dimensional model comprises the following steps: the method comprises the steps of splitting a structural monomer, forming a structural monomer stereogram, combining the structural monomers and forming an integral three-dimensional stereogram.
The multi-source data acquisition system 1 is used for splitting an entity object into a plurality of independent structural units and acquiring two-dimensional image information of the structural units from different shooting angles.
It should be added that when some structural monomers cannot directly obtain two-dimensional image information, that is, some structures are nested inside and cannot be disassembled, a three-dimensional image using the structural monomers can be directly searched.
The shooting angles of the structural units are divided into three groups of opposite surfaces, the shooting angles of the three groups of opposite surfaces are respectively a front surface, a back surface, a left surface, a right surface, an upper surface and a lower surface, the multisource data acquisition system 1 generally only selects one shooting angle of each group of opposite surfaces, and when structural differences exist in each group of opposite surfaces, the multisource data acquisition system 1 needs to acquire all shooting angles of one group of opposite surfaces.
Generally, the structural unit defines 6 observation surfaces, each of the 6 observation surfaces is grouped into three groups of opposite surfaces, the three groups of opposite surfaces are respectively a front surface and a back surface, a left surface and a right surface, and an upper surface and a lower surface, that is, shooting angles are selected from the opposite surfaces, if the structural shapes of the front surface and the back surface are the same, only one shooting angle of one opposite surface is selected, similarly, if the structural shapes of the left surface and the right surface are the same, only one shooting angle of one opposite surface is selected, and if the structural shapes of the upper surface and the lower surface are the same, only one shooting angle of one opposite surface is selected.
If the two shooting angles of the opposite surface are different in structural shape, shooting in two directions is needed, and then the same parts of the two shooting angles are fused together, so that a three-dimensional stereo image with a fully detailed structural monomer is formed.
When two shot images of a set of opposite surfaces are obtained, the two shooting angles are parallel to each other, so that when the same parts of the two shooting angles are fused, the accuracy of the structural position relation of the two planes can be ensured.
The single 3D processing system 2 is used for marking mapping points of two-dimensional image information edges at different angles, connecting the mapping points to form two-dimensional plane maps at different angles, extending the two-dimensional plane maps along the direction parallel to the shooting angle of the two-dimensional plane maps to generate a plurality of stereograms, and fusing the same parts of the stereograms to form the independent 3D stereogram of the structural single body.
After two-dimensional image information of each structural monomer at different angles is obtained, a plane diagram is obtained first, then the plane diagram is stretched in a three-dimensional mode to obtain an independent 3D stereogram of the structural monomer, and for the structural monomers at multiple shooting angles, the same parts of the stereogram can be fused to form the independent 3D stereogram of the structural monomer.
To sum up, the single 3D processing system 2 first obtains a perspective view of each angle, and then fuses all the perspective views to form an independent 3D perspective view suitable for different observation angles, as shown in fig. 2, specific steps of constructing the independent 3D perspective view by using the single 3D processing system 2 are summarized as follows:
s100, selecting two-dimensional image information of a group of opposite faces of the structural single body, marking mapping points of edges of the group of opposite faces, selecting the mapping points at inflection points of the structure generally, and connecting the mapping points to generate a basic two-dimensional plane map of each structure.
S200, connecting all the surveying and mapping points in sequence to create a basic two-dimensional plane contour map of the two-dimensional image information.
And S300, cutting each structural monomer into different stretching image layers according to the volumes of different lines of the basic two-dimensional plane contour diagram.
For example, when the three-dimensional shapes of the upper section, the middle section and the lower section of the contour line of one structural single body are different, the upper section, the middle section and the lower section can be divided into three stretching layers, and then the three stretching layers are respectively used for generating the three-dimensional structures with different shapes according to different three-dimensional stretching modes.
When the stretching layers are divided, the same contour line can be divided into different stretching layers, and the same contour line can determine stretching sizes of different stretching layers, for example, when the upper section and the middle section are cut, the same contour line exists, and when the three-dimensional stretching structures of the contour line are the same, the contour line can be used as the upper-section stretching layer or the lower-section stretching layer.
S400, correspondingly matching different stretching image layers into preset surface grids of the stereo image according to the shooting angle of the currently selected two-dimensional plane profile image, and stretching the preset surface grids along the direction parallel to the shooting angle to generate the stereo images at different angles.
In this step, the preset surface meshes are generally in the form of cones, cubes, cylinders, rings, pyramids, spheres, etc., and different contour line graphs are stretched into different three-dimensional shapes according to different preset surface meshes directly according to the shapes of the real objects.
S500, comparing the size of each group of opposite stereo images, modifying the stretching length according to the related size information of different groups of stereo images, and fusing all the stereo images to form the integral stereo image of each structural monomer.
Combining the above steps S400 and S500, the specific operation of stretching the contour map into a perspective view is as follows:
and selecting one stretching layer in the basic two-dimensional plane contour map at any shooting angle, selecting the central point of the stretching layer as a stretching origin, and stretching along the direction parallel to the shooting angle.
And adjusting the stretching length of each stretching layer in the same basic two-dimensional plane contour diagram, ensuring that the volume difference of different stretching layers is the same as that of a real object, generating a layered stereogram at each shooting angle, and marking the cross contact plane of the adjacent stretching layers in the layered stereogram.
And integrating the layered stereo images with the crossed contact planes at one time, and cutting to modify the volume shape of the crossed position of the layered stereo images.
Because different stretching layers exist in one structural monomer, when the stretching layers are respectively converted into the stereo images, due to the limited form of the preset grids, the stereo shapes of some stretching layers can not directly obtain a stereo cutting image when the preset grids are used for stretching, therefore, each stretching layer is reasonably stretched to generate the stereo image of a single layer, and then the stereo images of irregular stretching layers are cut by utilizing the cross fusion angle and the cross depth of two adjacent layers, so that the accuracy of the stereo shapes of the structural monomers is ensured.
And performing secondary integration on the modified layered stereogram to generate an independent 3D stereogram of each structural single body, and disassembling the stereogram of each structural single body again according to the division of the stretching layer, so that the information of the independent 3D stereogram of each structural single body is conveniently modified.
As one of the characteristic points of the present invention, the 3D model of the embodiment first splits a simulation object into a plurality of structure monomers, then splits each structure monomer into different layers, forms a stereogram of a single layer by stretching and fusing the different layers, and finally fuses the stereograms of the layers to generate a stereogram of the structure monomers.
Therefore, the 3D model of the embodiment has high accuracy, small units of the whole simulation object are simulated, the small units are combined into a large unit, characteristic information of a plurality of planes is acquired through collection, the details are more, the accuracy is more, therefore, the demonstration and explanation are facilitated, a user can be helped to understand the details and the working principle of the simulation object, and an ideal three-dimensional demonstration effect is achieved.
The 3D integration system 3 is used to combine all the independent 3D perspective views to generate a closed entity object overall 3D perspective view.
That is, after generating the independent 3D perspective views of the structural monomers, all the independent 3D perspective views are combined to form the overall 3D perspective view of the entity object, and the method for generating the overall 3D perspective view specifically includes:
sequentially stacking all the independent 3D stereograms;
determining nesting depth of two independent 3D stereograms with nesting relation, forming a cutting point at a nesting boundary position, and dividing the independent 3D stereograms into a plurality of cutting segments according to the nesting relation;
selecting a cutting segment on the independent 3D stereogram for hiding;
and selecting the exposed section and the hidden section of the independent 3D stereogram to combine the whole 3D stereogram, wherein the 3D integration system 3 is used for combining all the independent 3D stereograms to generate the closed entity object whole 3D stereogram.
The 3D integration system 3 combines a plurality of independent 3D stereograms into a whole, and can perform secondary disassembly according to the classification of the independent 3D stereograms, so that the explosion schematic diagram of the whole object can be conveniently demonstrated.
As the second most important feature of the present invention, most of the 3D models in the prior art can only obtain a three-dimensional perspective view of a simulation object, and are not easy to directly obtain internal parts, can not display complex parts of the simulation object, and inner and outer shape structures of an assembly body, so that the existing 3D models cannot visually help users to understand details and working principles of the simulation object, and cannot achieve an ideal three-dimensional display effect.
However, the 3D model provided in the present embodiment has the overall 3D perspective view combined by all the independent 3D perspective views, and all the independent 3D perspective views in the overall 3D perspective view can also be separated by disassembling.
That is to say, the 3D model can not only display the intuitive three-dimensional stereo image of the simulation object, but also directly disassemble the structural parts into a single body to carry out the explosive display of the three-dimensional stereo image of the simulation object because the three-dimensional stereo image of the simulation object is composed of single small structural parts, thereby helping a user to understand the details and the working principle of the simulation object and achieving the ideal stereo display effect.
The data storage system 4 is used for storing 3D stereograms of the entity object at different angles and in different states, and the generated structure single stereogram and the generated whole stereogram can be collected in the data storage system 4.
Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention.
