Device and method for producing panoramic image

A panoramic image generation method using a panoramic image generation apparatus, comprising:

• a photographing image input step of receiving a plurality of photographing image that has been photographed;
• a photographing information generation step of generating photographing information of the photographing images based on photographing posture information comprising photographed camera posture information of the photographing images;
• an image conversion step of generating output images that are obtained by converting the photographing images into low resolution images;
• an image storage step of storing the photographing images and the output images converted from the photographing images in a second memory unit;
• a photographing image output step of outputting the output images converted from the photographing images by disposing the output images in a three-dimensional space region based on the photographing information of the photographing images;
• and
• an image stitching execution step of generating a panoramic image by sequentially performing stitching on the plurality of photographing images corresponding to the output images disposed in the three-dimensional space region,
• wherein the photographing image output step comprises outputting the output images disposed in the three-dimensional space region by loading the output images stored in the second memory unit onto a first memory unit, and
• the image stitching execution step comprises loading the photographing images onto the first memory unit for the image stitching and performing the stitching between the photographing images loaded onto the first memory unit.
