| Abstract(in English) | 360° cameras have gained popularity over the last few years. Meanwhile, the development of Deep Neural Networks (DNNs) has dramatically improved the accuracy of object detection. However, the accuracy of object detection in 360-degree images has not been satisfactory due to the distortion of the equirectangular projection (ERP) images. In this paper, we propose a multi-view ERP representation as input for the training and inference of object detectors. In addition, we propose a data augmentation technique for object detection in 360° images. The proposed augmentation technique is specific to the 360° object detection task which randomly rotates the spherical image to improve the robustness against ERP image distortion. The proposed methods can be readily integrated into existing object detectors and significantly improve the performance. The experimental results show the significant effect of our method. |
