Abstract: A method of transmitting motion information for metaverse concert includes: generating, by a performance directing system, original motion information including frames where performer's action is recorded; generating processed motion information having a lower frames per second (FPS) than the original motion information; generating verified motion information by extracting information on position on a part of performer's body in the original motion information; transmitting the verified motion information to an audience client system; receiving the verified motion information; generating, by the audience client system, restored motion information having the same FPS as the original motion information by adding predicted frames for the removed frames to the processed motion information; verifying whether there is an error in the restored motion information; modifying and supplementing the restored motion information when there is the error; and assigning motion to a virtual character based on the supplemented motion information.

Abstract: Disclosed is a method of performing geometric correction on images obtained by multiple cameras and an image obtainment apparatus therefor, the method including: receiving the images obtained by the multiple cameras; extracting feature points of the received images and checking an interrelation between the extracted feature points; estimating locations and directions of the cameras, which respectively obtain the images, by using the interrelation between the feature points; calculating a relative geometric relationship between the multiple cameras from the estimated locations and directions of the cameras when the received images are determined as the images obtained by the multiple cameras with a fixed geometric interrelationship; and performing the geometric correction on each of the images by using the calculated geometric relationship. The method of efficiently performing geometric correction according to the embodiment of the present invention enables images to be obtained easily using the unmanned device with a short photographing time.
