Capturing nearly entirely spherical depth information using two adjacent frames from a single 360 degree video with motion parallax
3D scene reconstruction from monocular spherical video with motion parallax
We describe a method to capture nearly entirely spherical (360degree) depth information using two adjacent frames from a single spherical video with motion parallax.After illustrating a spherical depth informationretrieval using two spherical cameras, we demonstrate monocular spherical stereo by using stabilized first-person video footage.Experiments demonstrated that the depth information was retrieved on up to 97% of the entire sphere in solid angle.At a speed of 30 km/h, we were able to estimate the depth of an object located over 30 m from the camera.We also reconstructed the 3-dimensional (3d) structures (point cloud) using the obtained depth data and confirmed the structures can be clearly observed.
