Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Wherein the processor of the computer device is configured to provide computing and control capabilities.

The network interface of the computer device is used for communicating with an external terminal through a network connection. Optionally, the computer device may be a server, may be a PC, a personal digital assistant, other terminal devices such as a PAD, a mobile phone, and the like, a cloud, or a remote server, and the specific form of the computer device is not limited in this embodiment.
In the engineering design process, when a design model needs to be placed in a design area by the conventional technology, a designer usually depends on past design experience to manually select a proper position in the design area, and manually place the design model in the design area by operating computer equipment. However, the engineering design using this method is low in both design accuracy and design efficiency. The embodiment of the invention provides a method and a device for determining the pose of a model, computer equipment and a storage medium, and aims to solve the technical problems in the prior art.
The following describes the technical solution of the present invention and how to solve the above technical problems with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 2 is a schematic flowchart of a pose determination method for a model according to an embodiment. The embodiment relates to a specific process of reasonably unfolding a model to be placed by computer equipment according to the attribute of the model to be placed and scene environment information of a design scene. As shown in fig. 2, the method includes:
s101, determining a target expansion pose of a model to be placed by computer equipment according to the attribute of the model to be placed and scene environment information of a design scene; wherein the attribute of the model to be placed comprises the space geometric information of the model to be placed.
Specifically, the computer device may obtain the attribute of the model to be placed, and optionally, the obtaining of the attribute of the model to be placed by the computer may be manually performed by a designer through a mouse click, or may be performed by the designer through a selection instruction of the model to be placed input by a keyboard, which is not limited in this embodiment. Optionally, the attribute of the model to be placed may include spatial geometry information of the model to be placed, and the spatial geometry information of the model to be placed can represent the shape and size of the model to be placed. In addition, the computer device can combine scene environment information of the current design scene according to the spatial geometric information of the model to be placed, wherein the scene environment information of the design scene can represent spatial distribution in the current design scene, so that the computer device can determine an expansion position where the model to be placed can be placed in the current design scene and an expansion posture where the model to be placed is placed in the position according to the spatial geometric information of the model to be placed and the spatial distribution of the current design scene, wherein the expansion posture can include the orientation of the model to be placed; and the computer device takes the unfolding position and the unfolding posture as the target unfolding pose of the model to be placed.
For example, when the design scenario is a toilet and the model to be placed is a toilet model. According to the space geometric information of the toilet model, such as the shape and the size of the toilet model, and according to the scene environment information of the toilet, namely the space distribution in the toilet, the computer equipment can determine that the unfolded position is a position where the toilet model can be placed in a south-east corner of the toilet and 50 centimeters are close to the wall, and the direction of a water tank of the toilet model faces south, so that the unfolded posture of the toilet model is determined, and the target unfolded posture of the toilet model is obtained.
S102, the computer equipment expands the model to be placed in the design scene according to the target expansion pose.
It should be noted that each model may be expanded according to an expansion position (e.g., a coordinate point or an area) in combination with an expansion posture (e.g., orientation). Specifically, the target deployment pose may include a deployment position and a deployment posture of the model to be placed, so that the computer device may deploy the model to be placed on the deployment position according to the deployment posture to complete determination of the pose of the model to be placed, thereby implementing placement of the model to be placed in the design scene.
In this embodiment, the computer device determines the object expansion pose of the model to be placed according to the attribute of the model to be placed and the scene environment information of the design scene, and expands the model to be placed in the design scene according to the object expansion pose. The method provided by the embodiment can enable the computer device to automatically determine the target expansion pose of the model to be placed according to the attribute of the model to be placed and the scene environment information of the design scene, automatically expand the model to be placed in the design scene according to the target expansion pose, and automatically determine the pose of the model based on the pose, so that the model can be placed. Therefore, the designer does not need to manually select the specific placing position and the specific unfolding posture of the model to be placed through a mouse or other manual operation modes, and the design efficiency is greatly improved; and can make the designer concentrate on the design energy and ensure linking up of design thinking to make the designer can concentrate on considering the required model in this design scene from the function of design scene, rather than dispersing energy to the loaded down with trivial details such as the position alignment of specific every model and attitude adjustment, therefore, when very big improvement design efficiency, it has improved design quality greatly. And the computer equipment automatically determines the target expansion pose of the model to be placed according to the attribute of the model to be placed and the scene environment information of the design scene, and automatically expands the model to be placed in the design scene according to the target expansion pose, so that the design errors and design deviations caused by manual operation or insufficient experience of designers are further avoided, and the design accuracy is greatly improved.
As a possible implementation manner of the foregoing embodiment, on the basis of the foregoing embodiment, the scene environment information includes spatial geometric information of the design scene and existing model information in the design scene.
Specifically, the scene environment information may further include spatial geometry information of the design scene, for example, a spatial shape and a size of the design scene, and existing model information in the design scene, and the existing model information may include a shape, a size, a usage space, a pose, and the like of an existing model. It should be noted that the existing model information in the design scenario may include information of other models that have already been designed in the design scenario. For example, in the design process, a designer firstly chooses to design a wash basin model in a toilet and secondly designs a toilet model, so that when the toilet model needs to be placed after the design of the wash basin model is completed, the designed wash basin model is used as an existing model in the design scene, and the determination of the target unfolding posture of the toilet model is influenced, for example, the toilet model cannot be placed at the position where the wash basin model is placed.
In this implementation, the computer device uses the existing model information as a part of the scene environment information in the design scene, and can determine the target expansion posture of the model to be placed more reasonably according to the spatial geometric information of the design scene and automatically combine the existing model information of other models already designed in the design scene in the earlier stage when determining the target expansion posture of the model to be placed, thereby avoiding the problems of position conflict or unreasonable posture and the like between models designed before and after the model is designed manually, and making the target expansion posture of the model to be placed more correct and reasonable, thereby further improving the accuracy of design and further improving the design quality.
Fig. 3 is a schematic flowchart of a pose determination method for a model according to another embodiment. The embodiment relates to a specific process of determining the object unfolding pose of a model to be placed by computer equipment according to the attribute of the model to be placed and scene environment information of a design scene. On the basis of the above embodiment, the above S101 may include:
s201, the computer equipment determines a first candidate space in the design scene according to the space geometric information of the model to be placed, the space geometric information of the design scene and the existing model information in the design scene.
Specifically, the computer device may exclude an already occupied space from the design scene according to the spatial geometry information of the model to be placed, for example, the external dimensions of the model to be placed, and the spatial geometry information of the design scene, for example, the spatial shape and dimensions of the design scene, and in combination with the existing model information, for example, the shape, dimensions, usage space, and pose of the already designed existing model in the design scene, and use the remaining space in the design scene after the exclusion as the first candidate space. Therefore, the first candidate space is all the free space in the design scene.
S202, the computer equipment determines the target expansion pose of the model to be placed according to the first candidate space in the design scene and the positioning rule of the model to be placed; wherein the positioning rule is used for representing the allowable placing condition of the model to be placed.
Specifically, since the positioning rule can represent the allowable placement condition of the model to be placed, the computer device can select, in combination with the positioning rule of the first model to be placed, an expansion position where the model to be placed is allowed to be placed in the first candidate space, determine an expansion posture where the model to be placed is allowed to be expanded in the expansion position, and use the expansion position and the expansion posture as the target expansion posture of the model to be placed. Optionally, the placement allowing conditions may include installation allowing conditions and usage allowing conditions, so that the positioning rule may ensure that the target deployment pose determined by the computer device can be installed and used.
Optionally, the placement permission condition may further include an acceptable space size of the model to be placed, and an attribute of an associated model matching the model to be placed.
Specifically, the acceptable space size of the model to be placed may include the size of the model to be placed itself and the available space size of the model to be placed, for example, the positioning rule of the toilet model may include that the acceptable space size of the model to be placed is that the installation and use area is greater than 50 centimeters by 50 centimeters; the attributes of the correlation model matched with the model to be placed may include attributes of other correlation models correlated with each other matched with the installation and use characteristics of the model to be placed, for example, the correlation model correlated with the model to be placed toilet model is a wall model, and the attributes of the wall model are vertical walls, so that the vertical wall attributes can be matched with the toilet model, which allows normal installation and use of the toilet model.
Optionally, as another possible implementation manner of S202, on the basis of the foregoing embodiment, reference may also be made to the following embodiment shown in fig. 4, which is not described herein again.
In this embodiment, the computer device determines a first candidate space in the design scene according to the spatial geometry information of the model to be placed, the spatial geometry information of the design scene, and the existing model information in the design scene, and determines the target expansion pose of the model to be placed according to the first candidate space in the design scene and the positioning rule of the model to be placed. Because the positioning rule can represent the allowable placing condition of the model to be placed, the method adopted by the embodiment can enable designers to automatically determine the target unfolding posture for reasonably placing and reasonably unfolding the model to be placed according to the positioning rule without manually selecting the specific placing position and the specific unfolding posture of the model to be placed and manually considering whether the model to be placed meets the placing condition of a certain position space, and can automatically complete the reasonable placing of the model according to the positioning rule by computer equipment.
Fig. 4 is a schematic flowchart of a pose determination method for a model according to yet another embodiment. The embodiment relates to a specific process of determining the target expansion pose of a model to be placed by computer equipment according to a first candidate space and the positioning rule of the model to be placed. On the basis of the foregoing embodiment, the foregoing S202 may specifically include:
s301, the computer device screens out a second candidate space capable of placing the model to be placed from the first candidate space according to the acceptable space size of the model to be placed, and obtains the attribute of the existing model in the second candidate space.
Specifically, the computer device excludes, from the first candidate space, a scattered space in which the model to be placed cannot be placed in the spatial dimension according to the acceptable spatial dimension of the model to be placed, that is, excludes a space in which the model to be placed cannot be placed, for example, a slit space, and uses the excluded space as a second candidate space, so that it is known that the second candidate space can satisfy the placing of the model to be placed in the spatial dimension, that is, a condition of "placing in place". Meanwhile, the computer device may further obtain attributes of an existing model in the second candidate space, and optionally, the attributes of the existing model may include a usage space required by the existing model already existing in the second candidate space, for example, a usage space for a person to stand on needs to be reserved by the washbasin model; the attributes of the existing model may include installation conditions that the existing model in the second candidate space has matching the model to be placed, for example, a corner of a bathroom as the existing model may provide an installation location for a shower in the shower room model.
S302, selecting an unfolding position space from the second candidate space by the computer equipment according to the attribute of the association model and the attribute of the existing model in the second candidate space; wherein the attributes of the existing model in the unfolded position space match the attributes of the associated model.
Specifically, the computer device selects, from the second candidate space, a location space having an attribute of the existing model matching an attribute of the associated model thereof as an expanded location space according to the attribute of the associated model. For example, when the model to be placed is a shower room model, the model related to the shower room model is a corner, that is, the shower room is generally set up by the corner, and the attribute of the existing model is that the corner is a vertical wall, so that the computer device can be used as the unfolded position space according to the position space of the corner having the vertical wall in the toilet room. Optionally, the computer device obtains a usage habit of a user, and sets the position of the shower room and the direction of the toilet model to be the same direction, so that the computer device can select a position space in the same direction as the toilet model in the second candidate space as an expansion position space of the shower room.
As a possible implementation manner of S302, the steps shown in fig. 5 may be referred to. Optionally, as shown in fig. 5, the S302 may specifically include:
s401, the computer equipment selects a plurality of third candidate spaces from the second candidate spaces according to the attributes of the correlation model and the attributes of the existing models in the second candidate spaces, and the attributes of the existing models in the third candidate spaces are matched with the attributes of the correlation model.
Specifically, the computer device selects, from the second candidate space, a location space matched with the attribute of the associated model associated with the model to be placed as a third candidate space according to the attribute of the existing model in the second candidate space. The attribute matching between the two types of the data may include the same type, the same structure, or the same material characteristics, which is not limited in this embodiment. In general, the third candidate space may be plural. For example, when the model to be placed is a shower room model, the associated model of the shower room model is a corner model, i.e., the shower room is generally set up against the corners, and therefore, the computer device can select all the corner positions in the second candidate space as the third candidate space of the shower room.
S402, the computer equipment sorts the plurality of third candidate spaces according to a preset sorting rule, and selects a first third candidate space as the expansion position space; the sequencing rule comprises at least one of a model position correct rule, a model and whole consistency rule, a model cost and a model construction difficulty degree.
It should be noted that the preset ordering rule may include at least one of a rule for correct model position, a rule for consistency between models, a cost of a model, and a difficulty level of model construction. The model position correctness rule is used for judging whether the model to be placed is correctly placed, for example, if the attribute of the corner in the third candidate space is the corner formed by a glass wall, the shower room is placed at the corner, so that the shower head cannot be installed, and the space of the unfolded position is incorrect; the consistency rules of the models and the models are used for judging the matching degree of the models which need to be kept consistent, for example, the shower room model needs to be arranged right above the bathtub model, and the consistency is good if the shower room model and the bathtub model are completely aligned in the vertical direction; the model cost comprises the installation cost and the use cost of the model. For example, the cost of punching holes in glass is higher than that of punching holes in cement walls, so that cement walls can be selected preferentially when a model needing to be punched and installed is used; the above-mentioned model construction degree of difficulty, for example when the closestool is installed and is used, its space is bigger the installation degree of difficulty is smaller, it is more convenient to use, on the contrary, the space is smaller the installation degree of difficulty is bigger, it is more inconvenient to use.
Specifically, the computer device may rank the plurality of third candidate spaces according to a preset ranking rule by combining at least one dimension of the model position accuracy rule, the model and overall consistency rule, the model cost, and the model construction difficulty level according to a preset ranking rule, and ranking the degree of superiority and inferiority represented by the at least one dimension. Optionally, the computer device may determine the goodness grade of each third candidate space according to the weight preset by each dimension, arrange the goodness grades from high to low, and use the first-ranked, i.e., the third candidate space with the optimal comprehensive ranking as the expansion position space.
In this implementation manner, the computer device selects a plurality of third candidate spaces from the second candidate space according to the attribute of the associated model and the attribute of the existing model in the second candidate space, ranks the plurality of third candidate spaces according to a preset ranking rule, and selects the third candidate space located at the head as the expansion position space. In this implementation manner, the computer device can select a plurality of third candidate spaces from the second candidate space according to the attributes of the associated model and the attributes of the existing models in the second candidate space, and rank the degrees of superiority and inferiority of the plurality of third candidate spaces according to a preset ranking rule, so that the plurality of dimensions can be integrated, and a most reasonable third candidate space is automatically selected as an expansion position space, so that the model can be placed in the current design scene to be maximally accurate and reasonable, the design quality is higher, and the use comfort of a user is better.
S303, the computer equipment determines the unfolding posture of the model to be placed in the unfolding position space according to the space geometric information of the model to be placed.
Specifically, the computer device can determine the orientation, i.e. the unfolding posture, of the model to be placed in the unfolding position space according to the above space geometric information of the model to be placed, such as the shape and the size of the model to be placed, and by combining the installation and use requirements of the model to be placed.
As a possible implementation manner of S303, the step shown in fig. 6 may be referred to in S303, and optionally, the implementation manner may include:
s501, the computer equipment determines an expansion origin of the model to be placed according to the space geometric information of the model to be placed.
It should be noted that each model may set an expansion origin and a self coordinate system based on the expansion origin, and optionally, the self coordinate system may be a three-dimensional space coordinate system. Thus, when the model is developed, it can realize the development of the three-dimensional space of the model in accordance with the specific position of the development origin and the orientation of its own coordinate system based on the development origin.
Specifically, the computer device can determine a point of the model to be placed as the deployment origin according to the spatial geometry information of the model to be placed. Generally, the geometric midpoint of the model to be placed or the special structure point of the model to be placed can be selected, for example, the toilet model can take the center of the water outlet of the toilet as the deployment origin of the toilet model according to the space geometric information of the toilet model, or take the outermost midpoint of the toilet tank as the deployment origin of the toilet model. It should be noted that the unfolding origin determined by the computer device is different, and the corresponding unfolding modes are also different. In this implementation, the position of the deployment origin determined by the computer device is not particularly limited, as long as the model deployment can be implemented according to the deployment origin.
S502, the computer equipment determines the unfolding posture according to the unfolding origin, the relative position relation of the existing model in the unfolding position space and the unfolding environment.
Specifically, the computer device can determine the position of the deployment origin in the deployment position space according to the deployment origin and by combining the deployment position space, determine the orientation of the coordinate system based on the position of the deployment origin according to the relative position relationship of the existing model in the deployment position space, and determine the deployment posture of the model to be placed by combining the deployment environment around the deployment position. For example, when the toilet model is based on the midpoint of the outermost side of the water tank as the unfolding origin, the unfolding direction of the toilet model needs to be combined with the positions of other existing models in the toilet model, such as the position of an already-arranged wall model, and the unfolding environment of the toilet model is combined, and when the unfolding environment of the toilet model is a corner, the toilet paper box model can be arranged on the wall at the side of the toilet; when the expansion environment of the toilet bowl model is not a wall corner, the toilet bowl paper box model can be arranged on the same wall with the toilet bowl body, so that the toilet bowl model can be expanded in an extensible space direction which meets the preset requirement from the wash basin model, and installation and use are realized.
Optionally, the computer device may further perform size adjustment on the model to be placed according to the surrounding environment, so that the model to be placed is more convenient to install and use. For example, the size of the initial shower room model is only the size meeting the use requirement, as shown in fig. 6a, the shower room model occupies one corner of the bathroom, in order to make the shower room more convenient for the user to use, the size of the shower room can be adjusted according to the size of the bathroom under the condition that the space of the current environment allows, so that the size of the shower room model is the same as the width of the bathroom, as shown in fig. 6b, the use comfort of the shower room is improved, and the material cost and the installation cost of the shower room are reduced.
In the implementation mode, the computer equipment determines the unfolding original point of the model to be placed according to the space geometric information of the model to be placed, and determines the unfolding posture according to the relative position relation between the unfolding original point and the existing model in the unfolding position space. In this implementation, the computer equipment can determine the deployment origin of the model to be placed according to the space geometric information of the model to be placed, and determines the orientation of the coordinate system of the computer equipment based on the deployment origin, the relative position relation of the existing model in the deployment position space and the deployment environment, and then determines the deployment posture of the model to be placed, thereby realizing the reasonable deployment of the model to be placed. In this embodiment, computer equipment can combine the relative position relation of having the model in the expansion position space, will wait to place the model and carry out reasonable expansion automatically in this expansion position space, thereby will wait to place the model and place in current design scene with correct and reasonable gesture, it has avoided the designer manual setting to wait the design inefficiency that the expansion gesture that places the model leads to, design error and design deviation that the manual setting expansion gesture probably brought can also be avoided, when making design efficiency further improve, the accuracy and the rationality of its design further improve.
In this embodiment, the computer device screens out a second candidate space in which the model to be placed can be placed from the first candidate space according to the acceptable space size of the model to be placed, and obtains the attribute of the existing model in the second candidate space, in addition, the computer device selects an unfolding position space from the second candidate space according to the attribute of the correlation model and the attribute of the existing model in the second candidate space, and the computer device determines the unfolding posture of the model to be placed in the unfolding position space according to the space geometric information of the model to be placed, so that the target unfolding posture of the model to be placed is determined by combining the unfolding position space and the unfolding posture. In this embodiment, the computer device can automatically screen out a second candidate space in which the model to be placed can be placed from the first candidate space, and automatically determine an expansion position space in which the attributes of the existing model and the attributes of the associated model can be matched from the second candidate space according to the attributes of the existing model and the attributes of the associated model in the second candidate space, and further automatically determine the expansion posture of the model to be placed in the expansion position space according to the space geometric information of the model to be placed, so as to obtain the target expansion posture of the model to be placed, so that a designer does not need to manually select a specific placement position and a specific expansion posture of the model to be placed through a mouse or other manual operation modes, thereby greatly improving the design efficiency; and can make the designer concentrate on the design energy and ensure linking up of design thinking to make the designer can concentrate on considering the required model in this design scene from the function of design scene, rather than dispersing efforts to the loaded down with trivial details such as the position alignment of specific every model and attitude adjustment, consequently, when very big improvement design efficiency, improved design quality greatly. And the computer equipment automatically determines the target expansion pose of the model to be placed according to the attribute of the model to be placed and the scene environment information of the design scene, and automatically expands the model to be placed in the design scene according to the target expansion pose, so that the design errors and design deviations caused by manual operation or insufficient experience of designers are further avoided, and the design accuracy is greatly improved.
Fig. 7 is a schematic flowchart of a pose determination method for a model according to yet another embodiment. The embodiment relates to a specific process of expanding a model to be placed in a design scene by a computer device according to an object expansion pose. The model to be placed may include a main model and a sub model. Optionally, on the basis of the foregoing embodiment, as shown in fig. 7, the foregoing S102 may specifically include:
s601, the computer device adopts the target unfolding pose to unfold the main model in the unfolding position space.
It should be noted that the model to be placed may include a main model and a sub model, and optionally, the sub model may be one or multiple. For example, the toilet model may include a main model, i.e., a toilet body model, and may also include a sub model, e.g., a carton model; for another example, the wash station model may include a main model, i.e., a wash station body model, and may include two sub-models, e.g., two mirror front lamp models on the left and right sides. Specifically, the computer device unfolds the main model in the unfolding position space according to the target unfolding pose. Optionally, the computer device may adjust the size of the main model within the size variable range of the main model according to the size of the unfolding position space, so that the model to be placed is more convenient to use or more convenient to install.
S602, the computer device expands the sub-model in the expansion position space according to the first incidence relation between the main model and the sub-model.
Specifically, a first association relationship exists between the main model and the sub model, where the first association relationship may include a position association relationship between the main model and the sub model, and may also include a distance association relationship between the main model and the sub model. The computer device may unfold the submodel in the unfolding position space at a position where a distance from the main model meets a preset distance threshold range and a relative position from the main model meets a preset requirement according to the first association relationship between the main model and the submodel. For example, the first association relationship includes that the distance between the paper box sub-model in the toilet bowl model and the toilet bowl main model cannot exceed a preset distance threshold, otherwise, the use is inconvenient, so the computer device may expand the paper box model within a preset distance threshold range of the toilet bowl main model according to the first association relationship. Optionally, the computer device may further adjust the size of the sub-model within the size variable range of the sub-model according to the size of the expansion position space, and adjust the position of the sub-model within the preset distance threshold range, so that the sub-model is more convenient to use or more convenient to install.
In this embodiment, the computer device expands the main model in the expansion position space using the target expansion pose, and expands the sub model in the expansion position space according to the first association relationship between the main model and the sub model. According to the method adopted by the embodiment, the main model is automatically and reasonably unfolded through the computer equipment according to the unfolding pose of the target, the sub-model is automatically and reasonably unfolded in the unfolding position space according to the first incidence relation between the main model and the sub-model, so that the comprehensive unfolding of the model to be placed is automatically completed, and the problem that the unfolding of the sub-model is unreasonable due to the fact that only the pose of the main model is considered but the pose of the sub-model is not considered when the model is artificially designed is avoided.
