  • Patent number: 11207142
    Abstract: A composite image generation system comprises: a position information detection device that detects position information about a predetermined spot in a real space; and a processing device that generates a composite image in which a separately acquired superimposed image is overlaid onto a desired region in a camera image of the real space captured by a movably placed video camera, based on the detected position information. In the processing device, after performing an initial setting that sets a global coordinate system that serves as a reference when generating the composite image, the initial setting being performed while each optical marker is in a stationary state, position information about a peripheral marker used during the initial setting is reset according to a recognition state of the peripheral marker provided at a predetermined spot presumed to be disposed in the stationary state and a detection state from an acceleration sensor.

  • Patent number: 11055873
    Abstract: A composite image generation system comprises: a position information detection device 14 that detects position information about a predetermined spot in a real space; and a processing device 16 that generates a composite image in which a separately acquired superimposed image is overlaid onto a desired region in a camera image of the real space captured by a movably placed video camera 18, based on the position information from the position information detection device 14. The processing device 16 includes a position information specifying means 35 that adjusts a detection result from the position information detection device 14 to specify position information about a probe 19 used when superimposing the superimposed image onto the desired region.
