摘　　要：针对无人机难以搭载相机阵列飞行拍摄的问题,提出了一种单摄像机无人机获取裸眼3D视频的方法。该方法在平行摄像机阵列法的基础上,利用单摄像机无人机在水平方向匀速飞行拍摄视频,以一定帧距提取所拍视频的相应帧,来获取具有水平视差的多段视差视频,以此制作裸眼3D显示器所需的立体视频片源。针对不同场景的拍摄距离,可根据该方法计算选取不同的帧距来调整视差视频的水平视差值。通过在裸眼3D显示器显示,对比实验结果验证了该方法的可行性。本文为普通无人机拍摄真实3D场景制作成裸眼3D显示所需的视频提供了参考。A method of naked-eye 3D video acquisition using a single-camera unmanned aerial vehicle is proposed in order to solve the problem which is difficult for an unmanned aerial vehicle to carry a camera array flight shooting.The method uses a single-camera unmanned aerial vehicle to shoot videos at constant speed in a horizontal direction based on the parallel camera array.The videos with horizontal parallax are acquired by the corresponding frames which are extracted from the shot video with a certain frame distance.The stereo video source for a naked-eye 3D display is produced.The horizontal parallax value of the videos can be adjusted by different frame distances which can be calculated by the shooting distances of different scenes according to the method.The feasibility of the proposed method is verified by the comparison of the experimental results on a naked-eye 3D display.This research provides a reference for the videos naked-eye 3D display by shooting the real 3D scene using the normal unmanned aerial vehicle.
