In this embodiment, the client device 110 is preferably located at a first location, such as a construction site, and the server device 120 is preferably located at a second location, such as a data center. Through a network 105 , the server device 120 can be connected with one or more client devices 110 . In this embodiment, the network 105 is the Internet; but it is not limited thereto. In other different embodiments, the network 105 may also be a communication technology such as a local area network (Local Area Network, LAN), a telecommunications network (such as a network on a mobile phone), or a wireless network. For example, as shown in FIG. 1 , the client device 110 can be a tablet computer, and is coupled with the server device 120 through a wireless network. Through the connection with the server device 120, the client device 110 can request the server device 120 for various building model (Building Information Model, BIM) related data. The building model display system 100 of the present invention mainly stores the building model data in a storage module of the server device 120 . In this embodiment, the storage module can be a hard disk or any other media capable of storing data. In this embodiment, there is an actual distance between the first position and the second position. In other words, the client device 110 at the first location and the server device 120 at the second location may actually be located in different time regions and/or countries. In this case, when the relevant data of a building is needed, the client device 110 can request and obtain the relevant data of the architectural model corresponding to the building from the server device 120 through the network 105 .

FIG. 2 shows a three-dimensional architectural model of one floor of the building corresponding to the first position in FIG. 1 . It should be noted here that the diagram description is only for convenience of description. In other words, the three-dimensional building model is not limited to the shape and size shown in FIG. 2 ; in other different embodiments, the building model can be a plurality of floors. In this embodiment, as shown in FIGS. 1 and 2 , the server device 120 can store architectural models of various buildings. Specifically, the architectural model is a three-dimensional virtualized model of the whole or part of the actual building, and its dimensions preferably have the same ratio as the actual building. In other words, the size of the actual building can be calculated/converted based on the corresponding building model.

FIG. 3A is an exemplary diagram of a user interface of the client device 110 . In this embodiment, the client device 110 is preferably a tablet computer or a handheld computer, such as a notebook computer or a smart phone. In this case, the user interface of the client device 110 is an input interface and a display interface at the same time. However, in other different embodiments, the client device 110 may also be other electronic products capable of receiving instructions and displaying calculation results, such as desktop computers or workstations. In this embodiment, as shown in FIG. 3A , initially the client device 110 will not display any building-related images. The user must first log in to the server device 120 through the client device 110 to start using the functions of the architectural model display system 100 of the present invention. After successful login, in one embodiment, the client device browses the data of all building models stored on the server device 120 . Specifically, for example, the server device 120 can list all the stored building models as a table for the client device 110 to display. In this way, the user can select any required data related to the building model. After the building model is selected from the list, the server device 120 generates a two-dimensional building image 111 according to the building model selected by the user, and transmits the two-dimensional building image to the client device 110 . When the client device 210 receives the planar building image 111, it will be displayed on the user interface, as shown in FIG. 3A. In this embodiment, the plane building image 111 is a top view of the three-dimensional building model in FIG. 2 .

Next, as shown in FIG. 3B , the user can indicate a certain point position P and a direction D on the displayed planar building image 111 through the user interface of the client device 110 . Specifically, the fixed-point position P is a mark, which can represent a user's position in the planar building image 111 . In this embodiment, if the client device 110 is a tablet computer or a smart phone, the user can use its touch function to touch/click a certain point P on the plane building image 111, and dragging The action of can indicate a direction D. It should be noted here that the client device 110 is not limited to obtain the user's instruction through touch; in other different embodiments, the client device 110 can receive the user's instruction through other methods, such as a mouse And/or keyboard, speech recognition and other technologies.

FIG. 4A is a schematic diagram of an embodiment of the communication interaction between the client device 110 and the server device 120 . In this embodiment, the client device 110 generates a positioning indication and a direction indication according to the fixed point position P and the direction D respectively. Wherein, the client device 110 can further encode the positioning indication and the direction indication into a user indication, and transmit it to the server device 120 . However, in other different embodiments, the client device 110 may not encode the positioning indication and the direction indication as user indications, but directly transmit the positioning indication and the direction indication to the server device 120 . In this embodiment, after receiving the user instruction, the server device 120 first decodes it into a location instruction and a direction instruction, and determines that it corresponds to an observation position in the three-dimensional building model according to the location instruction. Specifically, the server device 120 will know the relative position of the fixed point P to the two-dimensional building image 111 according to the positioning instruction, and by comparing the two-dimensional building image transmitted to the client device 110 with the corresponding three-dimensional building model, it can calculate and determine An observation position corresponding to the fixed point position P in the building model. Specifically, the server device 120 calculates the relative three-dimensional position according to the two-dimensional fixed point position P. To this end, the server device 120 generates the observation position according to a preset height and the positioning indication. In this way, the server device 120 can determine the corresponding viewing position (stereoscopic position) from the fixed-point position P of the planar building image of the client device 110 . For example, if the default height is 180 cm, the observation position will reflect the default height and the fixed point position in the building model. However, in other different embodiments, the preset height can also be another number or can also be changed/updated by the client device 110 .

However, in another embodiment, the client device 110 may download the 3D building model from the server device 120 first. As shown in FIG. 4B , in this case, the client device 110 may receive a planar building image corresponding to the three-dimensional building model from the server device 120 . Then, the client device 110 can transmit the user instruction to the server device 120 according to the command input by the user. The server device 120 judges/calculates the observation position in the three-dimensional building model according to the three-dimensional building model and the user instruction, and transmits the observation position information to the client device 110 . After receiving the information, the client device 110 will update the fixed-point position in the plane building image according to the information.

In the embodiment of FIG. 4A , the server device 120 will generate and transmit a perspective view to the client device 110 according to the viewing position, the direction indication, a preset viewing angle range (viewing angle) and the three-dimensional building model. After receiving, the client device 110 will display the perspective view on the user interface, as shown in FIG. 5A . In this embodiment, the preset viewing angle refers to the angle at which the user can recognize the visual range in the building model at the viewing position in the three-dimensional building model with the direction D (direction indication) specified by the user. For example, if the default viewing angle range is 70 degrees, as shown in FIG. 3B , the perspective view generated by the server device 120 will be the normally observable visual range at a fixed point in the building, as shown in FIG. 5A. As shown in FIGS. 3B and 5A , when the user draws a direction D from a fixed point P on the user interface of the client device 110 , the client device 110 will simultaneously display a dotted line mark of the viewing angle range according to the direction D. In this embodiment, the range enclosed by the dotted line mark can be presented by color shading, such as yellow or any other suitable color. Although the preset viewing angle range is set to 70 degrees in this embodiment, in other different embodiments, the preset viewing angle range can be other degrees, or the user can draw the direction D and then use two The dragging action of the finger instantly expands or reduces the viewing angle range, so that the display range of the perspective view generated by the server device 120 can be relatively expanded or reduced. In addition, in this embodiment, the user can update information such as the fixed point position P, the direction D and/or the viewing angle range at any time through the user interface or the input interface of the client device 110 . In addition, in this embodiment, in the perspective view, the user can update the up-down angle of vision. For example, the user can drag two fingers on the perspective view, so that the server device 120 calculates a perspective view with a corresponding upper or lower angle to the client device 110 . However, in other different embodiments, the server device 120 may initially transmit the larger size/resolution perspective view to the client device 110 . In this case, the perspective view in FIG. 5A can be a partial display view of the higher size/resolution, and when the user indicates on the client device 110 that he wants to change the up/down angle of the perspective view, the client device 110 Simply move the display to a higher or lower position in this high size/resolution perspective. Therefore, the communication between the client device 110 and the server device 120 can be reduced, and the response time (response time) of the client device 110 to the user's command can be shortened.

FIG. 5B is a schematic diagram of another embodiment of the user interface of the client device 110 in FIGS. 3A and 5A . As shown in FIG. 5B , the client device 110 can simultaneously display the plane building image and the perspective view transmitted from the server device 120 . Specifically, as shown in FIG. 5B , the two-dimensional building image and the perspective view can be simultaneously displayed on the user interface of the client device 110 in layers or side by side. Therefore, since the fixed-point position P, direction D and/or viewing angle range can be updated at any time according to the user's preference, during the process of updating these data, the user can freely visit the building by watching the two-dimensional building image and the perspective view at the same time. A virtualized architectural model of a building in a first location. In addition, since the three-dimensional architectural model of the building is only stored in the server device 120 , all calculations for converting the planar image into a three-dimensional image are all borne by the server device 120 . Therefore, the client device 110 only needs to output instructions and receive the planar building image and perspective view of the server device 120 to provide the user with a simple, fast and convenient method for referring to the three-dimensional building model of the building.

FIG. 6A is a schematic flowchart of a method for displaying a building model of the present invention. The architectural model display method of the present invention is preferably used in an architectural model display system, such as the aforementioned architectural model display system. Wherein, the system includes the above-mentioned client device 110 and a server device 120 storing a three-dimensional building model. The method includes the following steps:

Step S100 includes using the client device 110 to receive a two-dimensional building image from the server device 120, wherein the two-dimensional building image is generated by a three-dimensional building model. Specifically, the client device 110 first requests data related to the three-dimensional building model from the server device 120 . Firstly, since the server device 120 may store a plurality of architectural models of different buildings, the client device 110 will first display the various architectural models stored in the server device 120 in a table on its user interface. Thus, the user in front of the client device 110 can select the relevant data of the building model to be viewed. For this selection, the server device 120 will generate a corresponding planar building image according to the selected building model, and transmit it to the client device 110 .

Step S200 includes using the client device 110 to generate and transmit a user command with a direction indication to the server device 120 according to the two-dimensional building image. In detail, in one embodiment, the client device 110 can generate a positioning indication and a direction indication respectively according to the fixed point position P and the direction D in the planar building image. Then, the client device 110 can generate a user instruction to the server device 120 according to the positioning indication and/or the direction indication. However, in other different embodiments, the client device 110 may directly transmit the positioning indication and/or the direction indication to the server device 120 without generating a user command.

Step S300 includes using the server device 120 to determine an observation position in the three-dimensional building model corresponding to the two-dimensional building image according to a user instruction. In this embodiment, after receiving the user command, the server device 120 will read the positioning indication and direction indication in the user command. The server device calculates the corresponding three-dimensional position (observation position) in the three-dimensional building model according to the positioning instruction and the preset height. Specifically, the three-dimensional position represents the observation position where the user stands virtually and can observe the architectural model corresponding to the fixed-point position P in the three-dimensional architectural model.

Step S400 includes using the server device 120 to generate a perspective view according to the three-dimensional building model, the observation position and the direction indication. Specifically, in this embodiment, the server device 120 calculates and generates a relative perspective view from the three-dimensional building model according to the observation position (stereo position) and direction indication. To put it simply, the server device 120 calculates in the three-dimensional building model, is located at the place where the viewing position is located, indicates the specified direction with the direction, and generates a perspective view according to a preset viewing angle range. In other words, this perspective view represents that the user is located at the fixed point P in the actual building, and can recognize the virtualized visual scene in the building in the direction of the direction D and within the visual range of the preset viewing angle range .

Step S500 includes receiving and displaying a perspective view by the client device 110 . In this step, the client device 110 will receive the perspective view generated by the server device 120 and display it on the user interface, as shown in FIG. 5A and/or 5B. In this way, since the building model is stored in the server device 120 and all calculations on the building model are processed by the server device 120, the client device 110 can quickly browse and visit the virtualized building.

Fig. 6B is a flow chart of another embodiment of Fig. 6A. As shown in FIGS. 6A and 6B , step S200 may include step S220 . Step S220 includes using the client device 110 to generate a user command according to a positioning indication and a direction indication. Specifically, the positioning indication and the direction indication are generated according to user input information received by the client device 110 on its user interface (input interface). The positioning instruction is based on the point position P that the user clicks on the two-dimensional building image on the user interface by touch or other methods. The direction indication is generated according to a dragging direction D drawn by the user after clicking the selected point P. The client device 110 will record the fixed-point position P and the direction D and the relative position in the plane building image to generate a user instruction.

As shown in FIG. 6B, step S300 may further include using the server device 120 to read the above-mentioned positioning indication and direction indication from the user instruction, and judge the position in the three-dimensional building model corresponding to the plane building image according to the positioning indication and direction indication. Viewing position (stereoscopic position). Specifically, the server device 120 will determine and generate the observation position according to the preset height and the positioning indication. In this way, the server device can determine the corresponding three-dimensional position from the fixed-point position of the two-dimensional building image of the client device 110 . In this way, the server device 120 can convert the plane position into a three-dimensional position.

As shown in Figure 7, the following steps may be further included after step S500:

Step 600 includes using the server device 120 to receive an updated positioning instruction from the client device 110; step 610 includes using the server device 120 to determine the three-dimensional position corresponding to the three-dimensional building model according to the update instruction, and generate the three-dimensional building model on the three-dimensional the perspective view of the location; and step 620 includes displaying the perspective view with the client device 110 .

FIG. 8 is a flow of the user inputting commands again when the client device 110 displays the perspective view and the two-dimensional building image at the same time, and the fixed-point position P has been set. As shown in FIG. 8 , steps 700 to 740 may be further included.

Step 700 includes using the client device 110 to simultaneously display the perspective view and the two-dimensional building image. Specifically, the planar building image and the perspective view can be simultaneously displayed side by side on the user interface of the client device 110 . Through this, since the fixed-point position P, direction D and/or viewing angle range can be changed at any time according to the user's preference, and then change these numbers, the plane building image and perspective view can freely visit the virtual virtual building of the first position. Architectural models. In addition, since the 3D architectural model of the building is only stored in the server device 120 , all image conversions from plane to 3D images are entirely borne by the server device 120 . Therefore, the client device 110 only needs to output instructions and receive the planar building images and perspective views from the server, so as to provide users with a quick and simple way to view/refer to the three-dimensional building model of the building.

Next, as shown in FIG. 8 , step 710 includes using the client device 110 to receive an operation instruction from a user interface thereof, calculate an updated positioning instruction and an updated direction instruction according to the operation instruction, and thereby generate an updated user instruction transmission to the server device 120. Specifically, when the client device 110 displays the perspective view and the two-dimensional building image at the same time, and the fixed-point position P has been set, the user can input commands on the user interface or input interface of the client device 110, as described above tap/touch or drag as described above. The client device 110 calculates and updates the positioning indication and/or the updating direction indication according to the action/operation command, and generates an updated user command to transmit to the server device 120 . For example, in one embodiment, if the user touches and selects a location on the displayed planar building image, the client device 110 will generate an update positioning instruction according to the location. The updated positioning indication represents the new fixed-point position P clicked by the user. The user can then input direction instructions, such as drawing a direction with a dragging action on a two-dimensional building image. The client device 110 will calculate the update direction indication according to the operation instruction, and generate an update user instruction to the server device 120 according to the update location indication and the update direction indication. However, in other different embodiments, the user does not need to input the operation instructions on the planar building image; the user can also input the above operation instructions on the perspective view.

As shown in FIG. 8 , step 720 includes using the server device 120 to determine an updated viewing position in the three-dimensional building model corresponding to the two-dimensional building image according to the updating user instruction. Specifically, the server device 120 reads the updated positioning indication and/or the updated direction indication from the updated user command, and calculates the corresponding new observation position (updated observation position) in the three-dimensional building model according to the updated positioning indication. . Step 730 includes using the server device 120 to generate an updated perspective view according to the three-dimensional building model, the updated observation position and the updated direction indication. Next, step 740 includes receiving and updating the updated perspective view by the client device 110 . In this way, when the client device 110 displays the perspective view and the two-dimensional building image at the same time, the architectural model display system 100 can quickly update the perspective view and/or the two-dimensional building image of the client device 110 at any time according to the user's operation. .

However, in another embodiment, if the client device 110 downloads the three-dimensional building model from the server device 120 first, the perspective view can also be generated by the client device 110 according to the received building model. Specifically, as shown in FIG. 9A, if the client device 110 has a stored three-dimensional architectural model, the architectural model display system 100 of the present invention may perform the following steps F100 to F400:

Step F100 includes using the client device 100 to display a two-dimensional building image, wherein the two-dimensional building image is generated from a three-dimensional building model. In detail, the client device 100 first downloads the three-dimensional building model from the server device 120 . In this embodiment, the planar building image is an image generated by the server device 120 according to the three-dimensional building model, and is transmitted to the client device 110 simultaneously with the three-dimensional building model. However, in other different embodiments, the two-dimensional building image can also be generated by the client device 110 according to the downloaded building model after the client device 110 downloads the three-dimensional building model.

Step F200 includes using the client device 110 to generate a user command with a direction indication according to the two-dimensional building image. Specifically, the client device 110 calculates the direction indication according to the operation actions/instructions input by the user on the two-dimensional building image displayed on the user interface. For example, if the user draws a line on the user interface, the client device 110 can calculate a direction according to the touch start point and end point, and generate a direction indication according to the direction. Then, the client device 110 encodes the direction indication into a user command.

Step F300 includes using the server device 120 to determine an observation position in the three-dimensional building model corresponding to the planar building image according to the user instruction. In this embodiment, although the client device has downloaded the three-dimensional building model and displayed the relative plane building image, when the user wants to change the position, the traditional building model display system cannot simultaneously display the perspective view and the The correct position of the image of the flat building. In other words, there is a discrepancy in the displayed position between the perspective view and the two-dimensional building image. Since the hardware device of the client device 110 may not be able to cope with the operation of updating the location in real time, in this embodiment, the operation is performed by the server device 120 . Specifically, the client device 110 will transmit the user command with directions to the server device 120 . The server device 120 judges/calculates the observation position in the three-dimensional building model according to the user instruction and the three-dimensional building model corresponding to the two-dimensional building image displayed on the client device 110 . The observation position is an updated position corresponding to the user in the three-dimensional building model.

Step F400 includes using the client device 110 to display relative fixed-point positions in the planar building image according to the observation position. Specifically, after the server device calculates the new observation location, it will transmit the observation location information to the client device 110 . The client device 110 updates the fixed-point position in the displayed planar building image according to the observation position information. Therefore, whenever the user wants to update the location, the fixed-point location of the client device 110 can be updated by calculating a new observed location through the server device. In this way, when the user browses the architectural model (through the perspective view and the planar architectural image), the client device 110 can display the correct fixed-point position, which can improve the convenience for the user to use the architectural model display system 100 .

Fig. 9B is another embodiment of Fig. 9A. As shown in FIG. 9B , step F500 may be further included. Step F500 includes using the client device 110 to generate and display a perspective view corresponding to the observation position according to the user instruction and the received three-dimensional building model. Specifically, in this embodiment, after the server device 120 generates a new observation position and transmits its information to the client device 110, the client device 110 can receive the stereoscopic view according to the instruction input by the user, The building model and viewing position information are generated and displayed relative to the perspective view. In this manner, when the user inputs an instruction to change the position, the client device 110 can instantly and simultaneously display the correct fixed-point position and perspective view to the user.

The present invention has been described by the above-mentioned related embodiments, however, the above-mentioned embodiments are only within the scope of implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the invention. On the contrary, modifications and equivalent arrangements included in the spirit and scope of the claims are included in the scope of the present invention.
