Abstract
In recent years, computational photography technology can achieve expressions by computational calculation. As part of this technology, it is now possible to synthesize multiple camera images into 360-degree images. Ricoh has developed the world's first consumer 360-degree camera, THETA, which generates 360-degree images by combining two low-parallax fisheye lenses through the stitching. This paper will explain the advances in this technology. In addition, business use of 360-degree cameras is expanding, particularly in the real estate and construction industries, taking advantage of their ability to capture images without blind spots. These services consist of image processing and recognition processing.
