Description

The present invention relates to a panoramic VR file providing apparatus that provides a panoramic VR file that allows an object to be observed from an arbitrary direction and displays an image with high texture reproducibility.

In recent years, with the diversification of consumer needs, products that allow consumers to freely customize the colors and options (accessories) of objects are increasing. In online shopping, it is often possible to purchase a product after browsing a Web page.
Under such circumstances, there is a system for displaying an image of a product customized according to a consumer's request on a Web page when shopping online.
For example, there is a system that displays a customized product image by combining two-dimensional images. In this system, it is possible to change and display the color and options of a product observed from a preset viewpoint position. This may be used for product images of a system kitchen or the like.
However, in a system that combines and customizes such a two-dimensional image, an image of a product observed from a preset viewpoint position is used. For this reason, only products viewed from a specific direction can be displayed, and it is difficult to display a product image with a texture.
Note that a panoramic VR image may be used to give the product image a texture. The panoramic VR image can rotate the background image of the object 360 degrees. As a system for generating this panoramic VR image, there is a three-dimensional panoramic image generating system that arranges a three-dimensional object image on a 360-degree background image captured while changing a certain angle by an imaging device such as a camera. (See Patent Document 1).
On the other hand, there is a system that displays an image using Web3D technology that renders three-dimensional CG data in real time. In this system, products with selected colors and options can be observed from any direction. Specifically, it may be used for product images such as cars.

JP 11-328443 A

However, in a system using Web 3D technology, 3D CG data is rendered in real time in a client terminal device. Therefore, before displaying the image, the product data and all the options and color data of the product must be downloaded. As a result, the initial download time increases as the amount of options and color data increases.
Web3D is assumed to be displayed on a terminal device of an arbitrary client. Therefore, a 3D simulation result that matches the specifications of the terminal device with the lowest possible performance is provided.
As a result, the accuracy and texture reproducibility of the image data is lowered, and a product image that gives an impression different from the actual product is displayed.

The panorama VR file providing system includes a terminal device 10 that reproduces and displays a panorama VR file connected via a network 5, and a panorama VR file providing device 20 that provides a panorama VR file.

  The terminal device 10 includes a reception unit 11, a transmission unit 12, a reproduction unit 13, and a control unit 14.

  The receiving unit 11 receives selection screen data and designated screen data, which will be described later, via the network 5. When a panorama VR file transmission request is sent to the panorama VR file providing apparatus 20, a panorama VR file corresponding to the request information is received.

  The transmission unit 12 transmits request information for requesting transmission of a panorama VR file based on selection data and viewpoint data described later to the panorama VR file providing apparatus 20. The selection data and the viewpoint data are set by an input / output unit (not shown) on the selection screen and the designation screen displayed by the selection screen data and the designation screen data transmitted by the panorama VR file providing apparatus 20.

  The reproduction unit 13 reproduces and displays the panorama VR file received by the reception unit 11 on a display unit (not shown). For example, it is realized by software such as QuickTime (registered trademark).

  The control unit 14 controls input / output of data in the terminal device 10.

The storage unit 21 stores a plurality of object data and background data for creating a panoramic VR file. Each object data is data including an object shape and a color attribute. Moreover, object data and background data can be used for all objects, both indoors and outdoors.

The receiving unit 22 receives request information including selection data and viewpoint data from the terminal device 10. The received selection data and viewpoint data are sent to the extraction unit 23 and the rendering processing unit 24, respectively.

Here, the “selection data” is data for selecting specific object data and background data from each object data and background data. Each object data and background data stored in the storage unit 21 is assigned an ID, and the object and background are uniquely specified by specifying the ID of the selected object data and background data. . That is, the selection data includes IDs of specific object data and background data.

“Viewpoint data” is data for designating the viewpoint position at which the selected object is observed.

The extraction unit 23 extracts object data and background data corresponding to selection data selected by the terminal device 10 from the storage unit 21. The extracted object data and background data are sent to the rendering processing unit 24.
