Patent number: 11861815Abstract: Provided are a method and apparatus for creating a composite image, by which the state of a target may be effectively expressed, and a computer program stored in a recording medium to execute the method. The composite image creating method, performed by a computing apparatus, of synthesizing an input image to a target image, includes identifying information of the input image by obtaining the input image, generating a projected image based on information about a position in units of sub-pixels for the target image of the input image, by using information of the input image, generating a reduced image by reducing the projected image at a ratio corresponding to the target image, and synthesizing the reduced image to the target image.Type: GrantFiled: March 23, 2023Date of Patent: January 2, 2024Assignee: AGENCY FOR DEFENSE DEVELOPMENTInventors: Hyun Ja Im, Jeongseaok Kim, Daeyeon Kim, Kwang Woo Park

Patent number: 8761934Abstract: A system achieves seamless localization for a plurality of robots when first some robots moves to a shadow area where GPS signals are not received while remaining second robots receives the GPS signals, by performing an absolute localization for the second robots using the GPS signals; and performing an absolute localization for the second robots using the GPS signals; performing a relative localization for the first robots based on the second robots, thereby determining an absolute location of the first robots. Further, when the second robots move to the shadow area where the first robots have been moved, the system performs the seamless localization by determining a relative location of the second robots based on the first robots on which the relative localization has been performed, thereby determining an absolute location of the second robots based on the relative location of the second robots.Type: GrantFiled: December 16, 2011Date of Patent: June 24, 2014Assignees: Electronics and Telecommunications Research Institute, The Industry & Academic Cooperation in Chungnam National UniversityInventors: Chang Eun Lee, Tae-Kyung Sung, Sung Hoon Kim, Hyun-Ja Im, Young-Jo Cho
