球面相机是一种可以在天球中拍摄全方位景观的相机。使用球形相机拍摄的图像可以使用等矩形投影进行转换，并且可以在所有方向上一起观看360°全景图像。然而，由于在360°全景图像的上部和下部中发生失真，因此即使通过人眼观看图像也难以识别对象并掌握对象的位置。在这项研究中，我们提出了一种方法来检测从球面相机获取的360°全景图像的对象，并估计从检测结果的对象的位置。通过校正估计位置误差，与校正前相比，精度提高了约2.5倍。
A spherical camera is a camera that can shoot omnidirectional landscapes in a celestial sphere. Images taken with a spherical camera can be converted using equirectangular projection, and 360° panoramic images can be viewed together in all directions. However, since distortion occurs in the upper and lower parts of the 360° panoramic image, it is difficult to recognize the object and grasp the position of the object even by looking at the image with the human eye. In this study, we propose a method to detect an object from a 360° panoramic image acquired from a spherical camera and estimate the position of the object from the detection result. By correcting the estimated position error, the accuracy was improved by about 2.5 times compared to before the correction.
