Referring to fig. 1, a flow of one embodiment of an information generation method according to the present disclosure is shown. As shown in fig. 1, the information generating method includes the following steps:

step 101, acquiring first acquisition point position information of a first image acquisition point of the three-dimensional room source model, and acquiring second acquisition point position information of at least one second image acquisition point in the three-dimensional room source model.

In this embodiment, an executing subject (for example, a server and/or a terminal device) of the information generating method may acquire first acquisition point position information of a first image acquisition point of a three-dimensional room-source model, and acquire second acquisition point position information of at least one second image acquisition point in the three-dimensional room-source model.

Here, the second image capture point is an image capture point of the three-dimensional origin model other than the first image capture point.

In some scenarios, a worker may go to a room source site to take a picture in the field, and in each room of the room source, one or more image acquisition points may be set, that is, room source images are acquired at one or more positions (room source acquisition points), and a three-dimensional room source model is built according to the acquired room source images. The image acquisition point of the house source site can be position information in a real house source space. The acquisition point position information of the three-dimensional room source model can indicate the position of an image acquisition point in a real space and the position of the image acquisition point in a virtual space of the three-dimensional room source model.

Based on the three-dimensional room source model, Virtual Reality (VR) panoramic virtual roaming can be realized. So-called virtual roaming, i.e. roaming in virtual reality. The specific implementation mode is that the virtual reality panorama is taken as a main body, various media such as pictures, videos, audios and characters are selectively added, and various scenes including house sources or scenic spots are integrally and comprehensively displayed, so that a viewer can not only obtain integral knowledge, but also can go deep into one scene and one detail to browse and watch.

In a related implementation scene of virtual roaming of the VR panorama, roaming point controls (used for indicating the position of a roaming point) of other VR panoramas can be added into the VR panorama or a map according to the position of an image acquisition point in a real house source control, the roaming point controls can be in the form of arrows or footprints, and when a browser clicks the roaming point controls of other VR panoramas, the browser can be switched to other three-dimensional panoramas to browse. In other words, when the user views the house source image in the virtual reality panoramic roaming scene, the displayed virtual scene can simulate the user to view the house source scene at the real position corresponding to the roaming point.

It is understood that one or more real-world source image capture points may be included in the real space of the real house source, and that a plurality of image capture points may be included in the virtual space of the three-dimensional house source model. Any acquisition point in the virtual space of the three-dimensional room source model can be used as a first image acquisition point and can be processed in the mode of the embodiment; accordingly, an acquisition point other than the first image acquisition point may be the second image acquisition point. Here, the first and second distinction between the image capturing point is for convenience of description, and does not constitute a limitation on the image capturing point.

And 102, determining whether a predefined obstacle sub-model in the three-dimensional room source model exists between the first image acquisition point and each second image acquisition point in the at least one second image acquisition point according to the second acquisition point position information, the first acquisition point position information and the three-dimensional room source model.

In this embodiment, the execution subject may determine, according to the second capture point position information, the first capture point position information, and the three-dimensional origin model, for each of the at least one second image capture point, whether a predefined obstacle sub-model in the three-dimensional origin model exists between the first image capture point and the second image capture point.

In this embodiment, the three-dimensional house source model may include a plurality of sub-models, such as a sub-model corresponding to a wall, a sub-model corresponding to a floor, a sub-model corresponding to a ceiling, and the like.

In this embodiment, the obstacle sub-model in the three-dimensional model of the house source may be predefined. For example, the predefined barrier sub-model may comprise a wall sub-model.

Alternatively, determining that a predefined obstacle sub-model exists between two image acquisition points may be achieved in various ways. For example, several rays are emitted from a first image acquisition point, and the rays are reflected when encountering a predefined obstacle sub-model, and are directed when not encountering the predefined obstacle sub-model, it is determined whether there are direct rays passing through a second image acquisition point among the rays emitted from the first image acquisition point, and if so, it is determined that there is no predefined obstacle sub-model in the three-dimensional room source model between the first image acquisition point and the second image acquisition point.

And 103, for a second image acquisition point without a predefined obstacle sub-model between the second image acquisition point and the first image acquisition point, determining a roaming point control of the second image acquisition point as a first type roaming point control of the first image acquisition point.

In this embodiment, a second image acquisition point may be a first type of corresponding acquisition point of a first image acquisition point if there is no predefined barrier sub-model between this second image acquisition point and the first image acquisition point. The first type of roaming point control corresponding to the acquisition point can be determined as a first type of roaming point control of the first image acquisition point.

It can be understood that the roaming point control of the first image acquisition point can be a roaming point control of the first image acquisition point, and the first-type roaming point control belongs to roaming point controls other than the roaming point control of the first image acquisition point.

Optionally, the first type of roaming point control of the first image capturing point may be a roaming point control which may be displayed in a process of displaying a three-dimensional panoramic image with the first image capturing point as a center. The second type of roaming point control of the first image acquisition point can be a roaming point control which cannot be displayed in the process of displaying the three-dimensional panoramic image with the first image acquisition point as the center.

Here, the waypoint controls may include various forms of information, such as text, e.g., images. If the waypoint controls include images, the specific styles for the images may also be varied, such as arrows, footprint images, circular images, and the like.

It should be noted that, in the information generating method provided in this embodiment, first acquisition point position information of a first image acquisition point of a three-dimensional room source model is obtained, and second acquisition point position information of at least one second image acquisition point in the three-dimensional room source model is obtained, where the second image acquisition point is an image acquisition point of the three-dimensional room source model other than the first image acquisition point; then, for each second image acquisition point in the at least one second image acquisition point, determining whether a predefined obstacle sub-model in the three-dimensional room source model exists between the first image acquisition point and the second image acquisition point according to the second acquisition point position information, the first acquisition point position information and the three-dimensional room source model; and if the roaming point control exists, determining the roaming point control of the second image acquisition point as the first type roaming point control of the first image acquisition point.

Therefore, the determined first-type roaming point control conforms to the objective scene when the user looks at the house in the field, specifically, when the user looks at the house in the field, objects seen at the image acquisition point include objects which are not blocked by barriers such as walls and do not include objects behind the barriers such as walls, so that the first-type roaming point can be displayed as an object which is not blocked in the scene of the house in the field, and the first-type roaming point control conforms to the objective cognition of the user on the relationship between the objects in the scene of looking at the house.

Referring to fig. 2, fig. 2 shows an application scenario according to the corresponding embodiment of fig. 1.

In fig. 2, the local contents of the three-dimensional model of the house origin are shown. The first image capturing point 201 and the second image capturing point 202 are located on two sides of the wall sub-model 204, and the first image capturing point 201 and the second image capturing point 203 are also located on two sides of the wall sub-model 204. A doorway area 205 is opened in the wall sub-model 204 to indicate a doorway.

In the scenario shown in fig. 2, it can be determined that there is no obstacle sub-model between the second image capturing point 202 and the first image capturing point 201 according to the first capturing point position information of the first image capturing point 201, the second capturing point position information of the second image capturing point 202, and the three-dimensional origin model, specifically, there is no obstacle due to the existence of the doorway area 205 between the second image capturing point 202 and the first image capturing point 201, and the intercommunication is achieved.

In some embodiments, the method further comprises: and for a second image acquisition point with a barrier sub-model between the second image acquisition point and the first image acquisition point, determining a roaming point control corresponding to the second image acquisition point as a second type roaming point control of the first image acquisition point.

Referring to fig. 2, according to the position information of the first collecting point of the first image collecting point 201, the position information of the second collecting point of the second image collecting point 203, and the three-dimensional house source model, it can be determined that a barrier sub-model (i.e., a wall sub-model) exists between the second image collecting point 203 and the first image collecting point 201. The second image acquisition point 203 in fig. 2 is a second type of corresponding acquisition point of the first image acquisition point, and the waypoint control of the second image acquisition point 203 is a second type of waypoint control of the first image acquisition point.

In some embodiments, the method further comprises: and when the three-dimensional panoramic image corresponding to the first image acquisition point is displayed, displaying at least part of the first type of roaming point control.

Referring to fig. 3, fig. 3 illustrates a scenario associated with the roam point control display.

In fig. 3, the waypoint control 301 is a waypoint control of the first image capturing point 201 itself, in other words, if the user triggers the waypoint control 301, the terminal may display a three-dimensional panoramic image centered on the first image capturing point 201. The roaming point control 302 is a roaming point control of the second image capturing point 202 itself, and when the user triggers the roaming point control 302, the terminal can display a three-dimensional panoramic image with the second image capturing point 202 as a center. The roaming point control 303 (actually not shown in dotted lines) is a roaming point control of the second image capturing point 203 itself, and when the user triggers the roaming point control 303, the terminal can display a three-dimensional panoramic image centered on the second image capturing point 203.

According to the example shown in fig. 2, the second image capturing point 202 is a first corresponding capturing point of the first image capturing point, and the waypoint control 302 of the second image capturing point 202 is a first type waypoint control of the first image capturing point, that is, a waypoint control which may be displayed during the process of displaying the three-dimensional panoramic image with the first image capturing point as the center. The second image acquisition point 203 is a second corresponding acquisition point of the first image acquisition point, and the roaming point control 303 of the second image acquisition point 203 is a second type roaming point control of the first image acquisition point, namely a roaming point control which cannot be displayed in the process of displaying the three-dimensional panoramic image with the first image acquisition point as the center.

Here, if the number of the first-type waypoint controls corresponding to the first image capturing point is at least two, all or part of the first-type waypoint controls may be displayed.

Optionally, when the user controls the angle of the displayed three-dimensional panoramic image to be aligned with the doorway area, the roaming point control 302 may be displayed; when the doorway area is not included in the three-dimensional panorama image that the user controls to be displayed, the roaming point control 302 is not displayed.

Therefore, when the three-dimensional panoramic image corresponding to the first image acquisition point needs to be displayed, the roaming point control which can be displayed in the three-dimensional panoramic image corresponding to the first image acquisition point can be quickly determined according to the type of the roaming point control corresponding to the first image acquisition point. The speed of displaying the roaming point control conforming to the cognition of the user in the objective scene is improved while the cognition of the user in the objective scene is conformed.

In some embodiments, the method further comprises: and responding to the detected trigger operation aiming at the displayed first-class roaming point, and displaying a three-dimensional panoramic image corresponding to the triggered first-class roaming point control piece.

In some embodiments, the waypoint controls may include a circular control or an elliptical control. The circular or oval roaming point is similar to the shape of a finger click when a human operates the terminal, so that the triggering operation of the user can be received to the maximum extent, and the operation efficiency of the user is improved.

By way of example, the screen may display a three-dimensional panoramic image corresponding to the roam control 301, and the user may click on the roam point control 302, where the roam point control 302 may indicate the three-dimensional panoramic image of the room b. The screen may then switch to displaying the three-dimensional panoramic image of room b.

Therefore, the user can conveniently operate according to the indication of the first-type roaming point control, the house-viewing path of the house is simulated on the spot, the accuracy rate of the user for acquiring the house source information is improved, and the speed of browsing the three-dimensional panoramic image corresponding to the house source is improved.

In some embodiments, the step 102 includes: generating a target line segment with the first image acquisition point and the second image acquisition point as endpoints; determining whether the target line segment has an intersection with a predefined barrier sub-model in the three-dimensional house source model.

As an example, referring to fig. 2, fig. 2 also shows an intersection 206 of a connecting line between the first image capturing point 201 and the second image capturing point 202 and a plane of the wall, where the intersection 206 is located in the doorway area 205, and is not located on the wall sub-model 204, and is determined to have an intersection; fig. 2 also shows an intersection point 207 of a connecting line between the first image capturing point 201 and the second image capturing point 203 and the plane of the wall, and if the intersection point 207 is on the wall sub-model 204, it is determined that there is no intersection point.

In some embodiments, the method further comprises: if the intersection point exists, determining that a predefined obstacle sub-model in the three-dimensional house source model exists between the first image acquisition point and the second image acquisition point; if there is no intersection point, it is determined that there is no predefined barrier sub-model in the three-dimensional origin model between the first image acquisition point and the second image acquisition point.

Therefore, whether a blockage exists between the first image acquisition point and the second image acquisition point can be quickly determined, and the first-type roaming point control can be quickly determined.

In some embodiments, prior to step 101, the method further comprises: and the server loads the three-dimensional room source model.

Here, the server may be the execution main body or other electronic device.

Here, the three-dimensional room source model may be loaded at the server, and then the

above steps

101, 102 and 103 are performed. In other words, under the condition that the three-dimensional panoramic image corresponding to the three-dimensional house source model is not displayed, the three-dimensional house source model is used for calculation, the position information of the image acquisition point is determined, and then the first type roaming point control of the first image acquisition point is determined. Therefore, timely display of the roaming point control can be achieved.

In contrast, if a three-dimensional house source model is loaded by using a browser, a corresponding three-dimensional panoramic image is displayed, and then the type of the roaming point control piece is determined, the roaming point control piece may not be displayed in time.

In some embodiments, the server loads a three-dimensional room source model, which may include: aiming at an interface of a browser called by a webpage graphic library, establishing a corresponding server-side interface; modifying an interface used for calling a browser in the webpage graphic library into the interface for calling the server; and running the modified webpage graphic library at the server side, and loading the three-dimensional house source model.

In some scenarios, the web page graphics library may invoke some functionality in the browser, enabling rendering of high-performance interactive 3D and 2D graphics. And the interface used for calling the browser in the webpage graphic library is modified to be the interface for calling the server, and the server correspondingly establishes the functions required by the webpage graphic library, so that the webpage graphic library can run at the server, and the three-dimensional house source model can be loaded by using the modified webpage graphic library at the server.

Here, the Web page graphics library (WebGL or Web graphics library) is a JavaScript API that can render high-performance interactive 3D and 2D graphics in a compatible Web browser without using a plug-in.

Therefore, the dependence of the WebGL on the browser can be stripped, and the WebGL can be used for rendering on the server side. The modified WebGL enables the browser-only loaded model to be loaded at a server side (without the browser), and the loading is carried out in a three-dimensional space.

Referring to fig. 4, fig. 4 illustrates another embodiment of an information generating method according to the present application. The embodiment shown in fig. 4 may comprise step 401, step 402, step 403 and step 404.

Step 401, the server loads a three-dimensional room source model.

Here, the server may be the execution main body or other electronic device.

above steps

101 and 102 are performed, and step 103 is performed. In other words, the three-dimensional house source model can be used for calculation to determine the position information of the roaming point without displaying the three-dimensional panoramic image corresponding to the three-dimensional house source model. Therefore, timely display of the roaming point control can be achieved.

In contrast, if a three-dimensional house source model is loaded by a browser, a corresponding three-dimensional panoramic image is displayed, and then the position information of the roaming point is determined, the position information of the roaming point may not be displayed in time.

Step 402, acquiring first acquisition point position information of a first image acquisition point of the three-dimensional room source model, and acquiring second acquisition point position information of at least one second image acquisition point in the three-dimensional room source model.

Here, the server may obtain first acquisition point position information of a first image acquisition point of the three-dimensional house source model, and obtain second acquisition point position information of at least one second image acquisition point in the three-dimensional house source model.

Step 403, determining, for each second image acquisition point in the at least one second image acquisition point, whether a predefined obstacle sub-model in the three-dimensional room source model exists between the first image acquisition point and the second image acquisition point according to the second acquisition point position information, the first acquisition point position information and the three-dimensional room source model.

Step 404, for a second image capture point for which no predefined barrier sub-model exists between the second image capture point and the first image capture point, determining a waypoint control of the second image capture point as a first type waypoint control of the first image capture point.

Step 405, when the three-dimensional panoramic image corresponding to the first image acquisition point is displayed, displaying at least part of the first-type roaming point controls.

Here, details of implementation and technical effects of each step corresponding to fig. 4 may refer to related descriptions of other parts of the present application, and are not described herein again.
