REMOTE RENDERING SYSTEM, IMAGE PROCESSING METHOD, SERVER DEVICE, AND PROGRAM
An object of the present disclosure is to provide a remote rendering system, an image processing method, a server device, and a program capable of efficiently performing pre-rendering, reducing a delay in displaying an image to a user, and reducing a deviation between a line-of-sight direction of the user and a rendered image. In order to achieve the above object, the remote rendering system according to the present disclosure includes a terminal having a sensor, and a server, the terminal transmitting information about a sensor state to the server, and the server transmitting a rendered image corresponding to the sensor state to the terminal, wherein the terminal transmits information about the current sensor state to the server, and the server predicts a plurality of possibilities of the sensor state to be expected in an immediate future based on the received information about the current sensor state, performs rendering corresponding to the predicted possibilities of the sensor state, and stores a plurality of the rendered images generated by the rendering.
1 . A remote rendering system comprising:
a terminal having a sensor; and
a server, wherein
the terminal comprising one or more processors configured to: transmit information about a sensor state to the server and transmit information about a current sensor state to the server,
the server comprising one or more processors configured to: transmitting transmit a rendered image corresponding to the sensor state to the terminal,
predict a plurality of possibilities of the sensor state to be expected in an immediate future based on the received information about the current sensor state,
perform rendering corresponding to each of the predicted possibilities of the sensor state, and
store a plurality of the rendered images generated by the rendering.
2 . The remote rendering system according to claim 1 , further comprising:
an application server, wherein
in a case where there is a plurality of servers, the application server comprising one or more processors configured to: select some of the plurality of servers and designate one of the selected servers as a master server and others as slave servers,
the terminal is configured to transmit information about the current sensor state to the master server,
the master server comprising one or more processors configured to predict a plurality of possibilities of the sensor state to be expected in an immediate future, and
at least one of the master server and the slave servers are configured to perform the rendering based on the predicted possibilities of the sensor state, and store the rendered image.
3 . The remote rendering system according to claim 1 , wherein the server is configured to: select, from the plurality of stored rendered images, the rendered image corresponding to the current sensor state, and transmit the selected rendered image to the terminal.
4 . An image processing method in which a terminal having a sensor and a server are included, the terminal configured to transmit information about a sensor state to the server, and the server configured to transmit a rendered image corresponding to the sensor state to the terminal, the method comprising:
transmitting information about a current sensor state from the terminal to the server;
predicting, by the server, a plurality of possibilities of the sensor state to be expected in an immediate future based on the received information about the current sensor state;
performing rendering corresponding to the predicted possibilities of the sensor state; and
storing a plurality of rendered images generated by the rendering.
5 . The image processing method according to claim 4 , further comprising:
in a case where there is a plurality of servers, selecting some of the plurality of servers and designating one of the selected servers as a master server and others as slave servers;
transmitting information about the current sensor state from the terminal to the master server;
predicting, by the master server, a plurality of possibilities of the sensor state to be expected in an immediate future; and
performing, by at least one of the master server and the slave servers, the rendering and storing the rendered image.
6 . The image processing method according to claim 4 , further comprising:
selecting, from the plurality of rendered images stored in the server, the rendered image corresponding to the current sensor state; and
transmitting the selected rendered image to the terminal.
7 . A server device that transmits, to a terminal having a sensor, a rendered image corresponding to a sensor state received from the terminal, the server device comprising one or more processors configured to:
receive information about a current sensor state from the terminal;
predict a plurality of possibilities of the sensor state to be expected in an immediate future based on the received information about the current sensor state;
perform rendering corresponding to the predicted possibilities of the sensor state;
store a plurality of rendered images generated by the rendering;
select the rendered image corresponding to the current sensor state from the plurality of rendered images stored in a storage unit; and
transmit the selected rendered image to the terminal.
8 . A program for causing a computer to function as the server device according to claim 7 .
