Detailed Description
As described in the background art, the data size is very large in the manner of simply presenting a three-dimensional model in the prior art; if the data amount of the model is reduced by compression, it is difficult to reveal detailed information that is sufficiently satisfactory to the user. The solution of using only the panoramic image can only provide two-dimensional image information, and cannot provide a three-dimensional structure, and the direct skipping of the images needs a large amount of manual labeling, so that the efficiency is very low.
According to the embodiment of the invention, the first picture of the space object is determined according to the position of the first click point determined by the first click operation of the three-dimensional model by the user, so that the three-dimensional model is displayed by switching to display at least one part of the first picture, the three-dimensional structure of the space object can be displayed through the three-dimensional model, and in addition, the details of the space object can be displayed through the first picture. By means of the mode of combining the three-dimensional model and the picture for display, the advantages of panoramic display and model display are combined, and the display effect of space display is improved.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 1 is a flowchart of a space display method according to an embodiment of the present invention.
The space exhibition method shown in fig. 1 may include the steps of:
step S101: when the three-dimensional model of the space object is displayed, determining a first click point based on a first click operation of a user on the three-dimensional model;
step S102: and determining a first picture of the space object according to the position of the first click point, and switching to display the three-dimensional model into display of at least one part of the first picture.
In this embodiment, when the three-dimensional model of the spatial object is displayed, the three-dimensional model may be displayed from a plurality of angles, such as a front view, a side view, a top view, or other angles determined by operations such as dragging by a user. Due to the different display angles of the three-dimensional model, the viewing angle of the user for observing the three-dimensional model is different.
In a specific implementation, the spatial object may have a three-dimensional structure, and may further have color information and texture information. The three-dimensional model of the space object can show the three-dimensional structure information of the space object so as to provide abundant three-dimensional space information for a user; the picture of the spatial object can show the color information and the texture information of the spatial object. Specifically, the spatial object may be any object having a three-dimensional structure, color information, and texture information, for example, a building, an apartment, or the like.
In a specific implementation, a user may click on various locations in a three-dimensional model while the three-dimensional model of a spatial object is presented. In step S101, a first click point is determined based on a first click operation of the three-dimensional model by the user. Specifically, when the three-dimensional model of the spatial object is displayed on the display screen, the user may click on the screen, and in step S101, the contact point between the user and the screen may be determined as the first click point.
In a specific implementation, the spatial object may have a plurality of pictures, and each picture may represent texture information and/or color information of a partial structure of the spatial object. In step S102, a first picture of the spatial object is determined according to the position of the first click point. That is, by the position of the first click point, the picture to be presented, i.e., the first picture, can be determined. Then, in step S102, the three-dimensional model is switched to be displayed to display at least a part of the first picture. In other words, the presentation of the three-dimensional model may be switched to the presentation of at least a part of the first picture to switch from the three-dimensional structure of the presentation space object to the texture information and/or the color information of the presentation space object, enabling an all-around presentation of the space object.
In this embodiment, the first picture of the space object is determined according to the position of the first click point determined by the first click operation of the user on the three-dimensional model, so that the display of the three-dimensional model is switched to display at least a part of the first picture, and further, the three-dimensional structure of the space object can be displayed through the three-dimensional model, and in addition, the details of the space object can be displayed through the first picture. By means of the mode of combining the three-dimensional model and the picture for display, the advantages of panoramic display and model display are combined, and the display effect of space display is improved. In other words, by using the three-dimensional model to display the whole three-dimensional structure of the space object, when the user needs detailed requirements, the user can jump to the picture display.
Preferably, step S102 may include the steps of: forming a ray according to the first click point, wherein the starting point of the ray is the first click point, and the extending direction of the ray is the view angle direction when the three-dimensional model is displayed; determining all intersection points of the rays and the three-dimensional model, and determining a first intersection point, wherein the first intersection point is the intersection point which is closest to the first click point in all the intersection points; searching a first shooting position closest to the first intersection point, and taking a shooting picture of the space object corresponding to the first shooting position as the first picture.
In a specific implementation, the three-dimensional model can be displayed from multiple angles during displaying, that is, there is a viewing angle direction during displaying the three-dimensional model. For example, the viewing direction may be a direction of a user's gaze relative to the three-dimensional model, and may be represented, for example, by an angle between the user's gaze direction and a reference line (e.g., normal, axis, etc.) of the three-dimensional model. Specifically, a first click point and a view direction when the three-dimensional model is displayed may form a ray, a starting point of the ray is the first click point, and an extending direction of the ray is the view direction when the three-dimensional model is displayed.
In a specific implementation, the ray has at least one intersection with the three-dimensional model. Specifically, the intersection point of the ray and the three-dimensional model may be an intersection point of the ray and a plane in the three-dimensional model, or an intersection point of the ray and a line in the three-dimensional model. For example, when the space object is an indoor space, the at least one intersection point may be a point of a ray and a wall surface of a living room, and a point of a floor surface of a bedroom, respectively. The first intersection point is an intersection point closest to the first click point among all the intersection points, and for example, the first intersection point is a point between a ray and a wall surface of a living room.
In a specific implementation, the spatial object may have a plurality of shooting positions, so as to perform comprehensive picture acquisition on a plurality of parts of the spatial object. Further, a first shooting position closest to the first intersection point may be searched, and a shooting picture of the spatial object at the first shooting position may be taken as the first picture, so as to display at least a part of the first picture. It should be noted that each shooting position may correspond to at least one picture taken at the shooting position.
Specifically, the first photographing position may be a position of the image pickup apparatus, so the first photographing position is generally located on the ground of the space object. For example, when the space object is an indoor space, the first photographing position may be a balcony floor, a doorway floor, or the like. Specifically, the display pictures of the spatial object are taken at a plurality of shooting positions. In other words, the plurality of shooting positions correspond to the plurality of panoramic views, and when the pictures need to be displayed, the pictures to be displayed can be determined in a mode of determining the shooting positions.
Preferably, the first picture is a panorama; step S102 may include the steps of: and switching to show the three-dimensional model to show the part of the first picture within the view angle range defined by the ray.
In a specific implementation, since the first picture may be a panorama, the panorama may include texture information and/or color information of 360 degrees in the horizontal direction; therefore, when the three-dimensional model is switched to show at least one part of the first picture, the part of the first picture within the view angle range defined by the ray is switched to show. In other words, the part of the first picture in the visual range of the user is displayed, so that the problems of distortion and low speed in displaying the panoramic picture are avoided, and the fluency of switching and displaying the three-dimensional model and the picture is realized.
Preferably, the space exhibition method shown in fig. 1 may further include the steps of: responding to a second clicking operation of the user in the first picture, and determining a second clicking point; and determining a second picture of the space object according to the position of the second click point, and switching to display the second picture. According to the embodiment of the invention, the second picture of the space object is determined according to the position of the second click point determined by the second click operation, the second picture is a picture to be displayed, and the first picture is switched to display the second picture. That is to say, the user performs the second click operation on the first picture, and can control to switch and display other pictures besides the first picture.
Preferably, the determining the second picture according to the position of the second click point may include the following steps: determining a second shooting position closest to the second click point according to the position of the second click point; and taking the shot picture of the space object corresponding to the second shooting position as the second picture.
In a specific implementation, when the second picture to be displayed is determined, the corresponding second shooting position is determined first, and the second shooting position can be determined according to the position of the second click point. If the position of the second click point is a shooting position, a shot picture of the display space object corresponding to the shooting position can be taken as the second picture; and if the position of the second click point is not the shooting position, searching a second shooting position closest to the second click point, and taking a shooting picture of the space object at the second shooting position as the second picture.
Specifically, a new ray can be formed with the first photographing position as a starting point and the direction from the first photographing position to the second photographing position as a direction. The second picture may be a panorama. Then, switching to show the second picture may be switching to show the first picture to show the portion of the second picture within the view angle range defined by the new ray. Wherein the new ray-defined view angle range may be a certain angle range centered on the new ray.
Preferably, the switching to show the second picture may include the steps of: responding to the second click operation, and projecting the first picture and the second picture on the three-dimensional model according to respective shooting positions; in the moving process of the observation point formed in response to the second click operation, switching to show the projection results of the first picture and the second picture projected on the three-dimensional model; and after the moving process of the observation point is finished, switching to display the second picture.
It is understood that, during the presentation, the observation point, i.e. the position where the user observes the three-dimensional model, and/or the angle or direction at which the user observes the three-dimensional model, may be determined according to the click operation of the user, etc. For example, the user may change the viewing direction at the viewpoint through a second click operation (e.g., drag rotation after clicking), and when the change in the viewing direction occurs at the viewpoint, the displayed pictures are different parts of the same panoramic image. For example, after the user performs a turning operation at the first photographing position, different parts of the first picture will be respectively displayed along with the turning operation.
It should be understood by those skilled in the art that any practicable operation may be adopted to project the first picture and the second picture on the three-dimensional model, and the embodiment of the present invention is not limited thereto. In other words, the projection process is also a rendering process of the three-dimensional model.
In a specific implementation, after the user performs the second click operation, the observation point may be moved in response to the second click operation, that is, moved from the first shooting position to the second shooting position. Specifically, the viewpoint may be a position in the three-dimensional model when the display picture is viewed, and the viewpoint may be a shooting position or a position other than the shooting position.
Compared with the direct switching between the display pictures in the prior art, when the first picture is switched into the second picture, the first picture is projected to the three-dimensional model for display, the second picture is projected to the three-dimensional model for display, and finally the second picture is displayed; the fluency of switching transition between the first picture and the second picture is realized by using the projection operation (namely rendering operation) of the three-dimensional model in the moving process of the observation point, the fluency and the immersion feeling of the pictures during switching display are further improved, and the user experience is optimized.
