Fig. 1 shows a kind of flow diagram of plane house type drawing generating method provided in an embodiment of the present invention.
As shown in Figure 1, plane house type drawing generating method provided in an embodiment of the present invention specifically includes the following steps:
S11, the top view or horizontal sectional view for obtaining three-dimensional building model；
Specifically, three-dimensional space model is to carry out real simulation to house panorama, and user is able to enter virtual three-dimensional space
Between in intuitively understand house type pattern.The top view of three-dimensional building model and the plane floor plan in house are opposite under normal conditions
It answers, if house is more than or cannot to obtain whole floor layouts from top view by one layer, three-dimensional building model can be intercepted
Horizontal sectional view respectively as each layer in house preliminary plane floor plan.
S12, plane floor plan is generated according to the top view or horizontal sectional view of the three-dimensional building model.
Specifically, plane house type required for the embodiment of the present invention is further generated by the top view or sectional view obtained
Figure.
Plane house type drawing generating method provided in an embodiment of the present invention, by the top view or water that obtain three-dimensional building model
Plane section figure generates the plane floor plan in house, can reduce the error of floor plan size, and efficient quick.
On the basis of the above embodiments, the method also includes:
The method for generating three-dimensional building model:
Fig. 2 shows a kind of flow diagrams for the method for generating three-dimensional building model provided in an embodiment of the present invention.
As shown in Fig. 2, the method provided in an embodiment of the present invention for generating three-dimensional building model specifically includes the following steps:
S21, the 3D point cloud data and realistic picture for obtaining house three-dimensional space；
Specifically, the embodiment of the present invention is scanned house by the equipment of profession, for example, by using infrared induction camera
House is scanned, the picture of each object in the room house Nei Ge and room is obtained, the three of the point cloud of each plane in each room
Coordinate is tieed up, point cloud refers to the point data set of the body surface obtained by measuring instrument, indicates usually using three-dimensional coordinate.By
The spacing between each plane in this available each room, moreover it is possible to obtain door and window material, thickness of wall body, pipeline
The various dimensions houseclearing such as parameter.
S22, house three-dimensional space model frame is built according to the 3D point cloud data of acquisition；
Specifically, collected point cloud data is uploaded to server, each plane is formed by planarization process, thus
Constitute three-dimensional frame diagram.
S23, the house three-dimensional space that will acquire realistic picture that the house put up is attached to according to default corresponding relationship is three-dimensional
On each face of spatial model frame, three-dimensional building model is generated；
By the image of each object in each room and room, relationship is laid in three-dimensional to the embodiment of the present invention according to a certain percentage
In house architecture diagram, image and three-dimensional house framework is set to match, to generate final three-dimensional building model.
On the basis of the above embodiments, S12 is specifically included:
The top view or horizontal sectional view are converted into the first plane floor plan；
Door and window information is added in the first plane floor plan, generates final plane floor plan.
Specifically, the top view or horizontal sectional view extracted by three-dimensional building model will appear lacking for door and window information
It loses, it is therefore desirable to determine the position of the door and window in top view or horizontal sectional view.
Specifically, described that door and window information is added in the first plane floor plan, final plane floor plan is generated, is had
Body includes:
According to the position of lines absent region and size in the first plane floor plan, in the first plane floor plan
Corresponding door or window are added in middle lines absent region, generate final plane floor plan.
Due to door and window and seam between the walls, the point cloud data of acquisition seam topagnosis, therefore first
The position that lines lack in plane floor plan is the position of door and window, adds door and window in corresponding position, generates complete plane
Floor plan.
For example, the length and width in the region that lines lack in the first plane is respectively in preset first group of numerical intervals
Interior or length and width ratio is greater than the first numerical value, then determine the region for the position of door, and by the length in the region and
Width size is converted to the ratio of the first plane floor plan addition table in the first plane floor plan according to top view or sectional view
Show the lines of door.
Similarly, the length and width in the region that lines lack in the second plane is respectively in preset second group of numerical intervals
Interior or length and width ratio is less than second value, then determine the region for the position of window, and by the length in the region and
Width size is converted to the ratio of the first plane floor plan addition table in the first plane floor plan according to top view or sectional view
Show the lines of window.
Specifically, above-mentioned first group of numerical intervals, the first numerical value, second group of numerical intervals and second value can be according to true
The practical door and window dimension information of the source of houses is preset.
In addition, change of the embodiment of the present invention according to the density and each plane inner region material of the point of collected each plane
Change the position to judge door and window in three-dimensional building model.For example, not produced since door and window and wall have gap in sweep time gap
Raw point data, therefore may become smaller in the density of scanning to door and window when point.According to features described above, the embodiment of the present invention is worked as
When judging that the density of the point of a certain region acquisition is less than first threshold, determine that a certain area for door, or is being judged in the region
When the density of the point of domain acquisition is less than second threshold, determine the region for window.
Similarly, the material of door and window is also different from wall, and therefore, the embodiment of the present invention is according to different zones material
Variation is to judge being door or window.When the collected material information in region a certain in plane be the first material, determine the region
For door, or when in plane a certain collected material information in region be the second material, determine the region for window.
Then, by above-mentioned zone, door or window are added in corresponding position in the first plane floor plan, generate final
Plane floor plan.
On the basis of the above embodiments, door and window information is added in the first plane floor plan, generates final put down
Face floor plan, specifically includes:
The door and window information that user draws in the first plane floor plan is received, final plane floor plan is generated.
Specifically, in user, according to the position and size information of door and window, the corresponding position in the first plane floor plan is added
After door or window, the final plane floor plan comprising door and window information can be generated.
Alternatively, the embodiment of the present invention can be automatically in corresponding position according to the judgement in the region lacked to each plane lines
It sets and generates door and window, form final plane floor plan.
The embodiment of the present invention can add house dimension information in the plane floor plan ultimately generated, such as each room
Length and width, so that user intuitively understands the pattern of house type.
