The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
These and other aspects of embodiments of the invention will be apparent with reference to the following description and attached drawings. In the description and drawings, particular embodiments of the invention have been disclosed in detail as being indicative of some of the ways in which the principles of the embodiments of the invention may be practiced, but it is understood that the scope of the embodiments of the invention is not limited correspondingly. On the contrary, the embodiments of the invention include all changes, modifications and equivalents coming within the spirit and terms of the claims appended hereto.
Referring to fig. 1, a method for editing an object in a panoramic image according to a first embodiment of the present invention is applied to editing an object in a panoramic image, where the object in the panoramic image includes a display board and an exhibit, and a user of the display board carries the exhibit, i.e., the exhibit is disposed on the display board.
And step S11, obtaining a display board type parameter selected by a user through a display board creation window, and obtaining the position coordinate of a display board to be created in the panoramic image, wherein the display board type comprises a horizontal display board, a front display board and a side display board, and the display board types respectively correspond to three dimensional surfaces of the local three-dimensional rectangular coordinate model of the view center point.
The user of the embodiment can arrange the display board through the display board creation window provided by the computer system. For example, when a user needs to set a panoramic VR scene, the display board creation window is displayed in the middle of the left side of the working area after a "display board layout" button on an interface toolbar of the display board creation window is clicked through an input device, three display board type options are set on the display board creation window, namely a horizontal display board, a front display board and a side display board, which correspond to three dimensions of a local three-dimensional rectangular coordinate model of a view center point, namely three planes determined by three coordinate axes. The viewing angle orientation of the observer in the three-dimensional space can be determined through the three types of display boards, for example, a horizontal display board refers to a plane piece below or above the observer and parallel to a horizontal plane; the front panel is a surface patch on the plumb bob surface which is right in front of the sight of an observer and is vertical to the horizontal projection of the sight of the observer; the viewer's line of sight and a perpendicular line perpendicular to the viewer's line of sight form a side, and the side panel is a facet parallel to the side.
The user may select any point in the panoramic image and create one of the types of panels at that point. In a specific implementation, a user may select a location point for creating a display board on the panoramic image through an input device such as a mouse or a touch display screen.
And step S12, creating a display board according to the display board type parameters and the position coordinates.
In this embodiment, the display board is set by the three-dimensional plane of the three-dimensional stereo model, and when the user selects one type of display board, the viewing direction of the display board is determined. When the system acquires the type parameters and the position coordinates input by the user in the operation, the display board in the visual angle direction is established on the position coordinate point. The coordinate system adopted in the panoramic image is generally a spherical coordinate system, and three types of display boards in the rectangular coordinate system are established in the embodiment for the convenience of arrangement and adjustment of the display boards in the embodiment. The adjustment for each type of board may only require adjustment in the corresponding two-dimensional plane.
In the above step, the specific step of creating the display board according to the display board type and the position coordinates includes:
step S121, determining the view angle position of the display board to be created in the panoramic image according to the display board type parameters;
and S122, creating a surface patch with a preset size according to the visual angle direction and the position coordinates to serve as a display board.
And establishing a surface patch on the visual angle direction at the position coordinate point, and taking the established surface patch as the created display board. The size of the patch is preset, for example, the square size is 2cm × 3cm, the effect of the patch is rendered based on the sphere coordinate and rectangular coordinate transformation model, the color of the patch filling can be preset, for example, gray, and a certain transparency can also be set.
Step S13, obtaining a first adjusting parameter for the display board, and adjusting the display board according to the first adjusting parameter, wherein the first adjusting parameter comprises at least one of width, height, horizontal offset and vertical offset.
The display board size created in step S12 is preset, which may not meet the user' S requirements. Therefore, the display board creation window in the present embodiment is provided with buttons for adjusting the width, height, horizontal offset, and vertical offset of the display board. The button is, for example, an adjusting bar, and the size of the display board is adjusted by moving an adjusting block on the adjusting bar. It is understood that in other embodiments of the present invention, the width, height, horizontal offset and vertical offset of the display board can be adjusted by setting up add-subtract buttons.
The width and height of the display board refer to the width and height of the surface patch in the corresponding view angle orientation of the display board. When the user needs to adjust the width of the display board, the adjusting block on the width adjusting strip can be moved to adjust the width of the display board in a scaling mode. At the moment, the system obtains that the first adjusting parameter is the width parameter, the system zooms the width of the display board according to the width parameter, meanwhile, the width of the surface patch corresponding to the display board in the panoramic image is correspondingly changed, and a user can visually see the adjusted size of the display board.
When the user needs to adjust the height of the display board, the adjusting block on the height adjusting strip can be moved to adjust the height of the display board in a scaling mode. At the moment, the system acquires that the first adjusting parameter is the height parameter, the system zooms the height of the display board according to the acquired height parameter, meanwhile, the height pair of the surface patch corresponding to the display board in the panoramic image changes, and a user can visually see the adjusted size of the display board.
When a user needs to adjust the display board in the three-dimensional space in the horizontal direction, the adjusting block on the horizontal offset adjusting strip can be moved. At this time, the first adjustment parameter acquired by the system is a horizontal offset, and the system offsets the display board by the horizontal offset in the horizontal direction, so that the display board moves by the distance of the horizontal offset in the horizontal direction.
When a user needs to adjust the display board in the vertical direction in the three-dimensional space, the adjusting block on the vertical offset adjusting strip can be moved. At this time, the first adjustment parameter acquired by the system is a vertical offset, and the system vertically offsets the display board by the vertical offset, so that the display board moves by the distance of the vertical offset in the vertical direction.
The horizontal direction and the vertical direction are two coordinate axis directions of a local plane rectangular coordinate system of the display board plane, for the front display board and the side display board, the horizontal direction is an in-plane horizontal straight line, and the vertical direction is an in-plane vertical line; for a horizontal display board, the horizontal direction is the left-right direction, and the vertical direction is the forward-backward direction.
And step S14, creating an exhibit on a target exhibit board selected by the user through the exhibit arrangement window, wherein the exhibit is any one of text, animation, video and model.
The user can create a plurality of display boards through the display board creation window, and can create an exhibit on any one of the display boards. The creation of the exhibit can be performed through an exhibit arrangement window provided by the system, for example, the exhibit arrangement window is displayed in the left center of the working area after a toolbar "exhibit trial exhibition" button is clicked, and meanwhile, the exhibition plate creation window is hidden.
The user can select a target display board by means of a mouse or a touch display screen, and when the system receives a selection signal of the user, the system marks the target display board selected by the user (for example, the selected display board is represented by a white line frame) to create an exhibit on the selected target display board according to the type of the exhibit provided in the exhibit layout window.
Step S15, obtaining a second adjusting parameter aiming at the exhibit, and adjusting the exhibit according to the second adjusting parameter, wherein the second adjusting parameter comprises at least one of width, height, horizontal offset and vertical offset.
The user can adjust the width, height, horizontal offset and vertical offset of the created exhibit through the exhibit arrangement window. The exhibit is placed on the panel, and the coordinate calculation of exhibit can be formed by the coordinate and the level of panel, the vertical offset combination, and when the second parameter that the system obtained the exhibit to adjust, the size and the offset position of adjustment exhibit, the regulation mode of exhibit is based on the regulation of panel, promptly in panel local coordinate system, realizes the readjustment to the exhibit position state through the regulation to each item parameter.
The embodiment of the invention can edit the objects in the panoramic image and can be divided into two links of the creation of the display board and the arrangement of the exhibits. The two stages can respectively finish different operation contents, clearly define the operation boundaries of two work types of display position customization and exhibit parameter editing, and the two operation links can be distributed to two batches of operators with different authorities to finish the two work types, so that the complexity of generating, arranging and editing the multimedia elements is reduced.
The exhibit arrangement stage can create exhibits on the display board, such as creating text content, picture content, animation content, video content or three-dimensional model content, and the like, and set interactive click actions of the multimedia element hot spots, such as opening a new window or popping up a detail window.
The display board is created based on three-dimensional planes under a three-dimensional rectangular coordinate system, namely a horizontal display board, a front display board and a side display board. The user can adjust the width, height, horizontal offset and vertical offset of each display board. According to the embodiment of the invention, the positions of the display board and the exhibits can be adjusted under the rectangular coordinate system, and the natural posture adjustment and matching can be realized by arranging the exhibits on the object in the panoramic image.
