摘要： Implementations relate to a computer-implemented method and a device for determining a relative posed between devices. The method can include receiving data representing first keypoint features from a first image captured by a camera of a second mobile computing device; capturing, by a camera of a first mobile computing device, a second image, wherein the first image and the second image comprise a substantially common scene having an area of overlap; computing, by the first mobile computing device, data representing second keypoint features from the second image; determining, by the first mobile computing device, based at least in part on the data representing first keypoint features and the data representing second keypoint features, a relative pose of the first mobile computing device and the second mobile computing device; and communicating the relative pose to the second mobile computing device.

摘要： This invention discloses a multi-pitching angle suspended space 3D display device with 360° FOV, comprising: a transmitted composite deflective diffusing screen, a high speed projector, an image generator, a detecting module and a rotating drive mechanism. The high speed projector projects the composite images of the 3D objects of different pitching angles and horizontal 360° views to the composite deflective diffusing screen that rotates at a high speed. The composite deflective diffusing screen is able to control the vertical deflecting and scattering angles and horizontal diffusing angle for incident rays with different angles, allowing the surrounding viewers at different height levels to see the images corresponding to their viewpoints, making the displayed 3D objects suspended over the composite deflecting scattering screen, of which the position does not change as the height of the viewpoint changes. The multi-pitching angle suspended space 3D display device with 360° FOV allows watching by multiple persons at multiple pitching angles and horizontal 360° FOV in naked eyes, realizing space occlusion, exploration and interaction.

摘要： The present invention discloses a full parallax three-dimensional display device. It comprises a projector array and an orthogonal cylinder raster screen. The orthogonal cylinder raster screen comprises the first cylinder raster and the second cylinder raster. The projector array and the orthogonal cylinder raster screen are put in order. The projector array projects images on the orthogonal cylinder raster screen. The raster directions of the first cylinder raster and the second cylinder raster of the orthogonal cylinder raster screen are parallel to the x-axis and the y-axis, respectively. The advantage of the present invention is that it can generate 3D images of high image resolution and high view-field resolution. The extremely tiny view field intervals can bring completely continuous and jumping-free 3D perception for the viewer, reduce the fatigue caused by discontinuous view field in conventional 3D display, and achieve full parallax 3D display including horizontal parallax and vertical parallax.
