We hope that the Special Section will also help researchers exchange the latest technical progress in the field. This Special Section aims to review the latest results of image panorama techniques and devices in gigapixel panoramic video construction, as well as their applications. Size, weight, power and cost of the devices are central challenges in gigapixel panoramic video. At present, all existing panoramic video devices use tiled multiscale image structures to enable viewers to interactively explore the captured image stream. The processing of gigapixel panoramic video construction involves several stages including video stabilization, dynamic feature tracking, vignetting correction, gain compensation, loop optimization, color consistency and image blending. Generally, the key step for constructing gigapixel panoramic video is to stitch unsynchronized videos into a large-scale dynamic panorama. In the fields of virtual reality and augmented reality, content creators have constructed gigapixel panoramic video in order to deliver stories with more visually immersive experiences than previously possible.Īlthough constructing image panoramas by assembling multiple photos from a shared viewpoint is a well-studied problem, it is still difficult to construct large-scale panoramic video. Panoramic video streaming services are now available through companies such as YouTube and Facebook, and head-mounted display devices such as Samsung Gear VR and Oculus Rift, which support 360-degree viewing, are starting to be more commonly used. This potential change of the viewing paradigm arising from the use of gigapixel panoramic vides has attracted much attention from the industry and the general public. This allows a viewer to interactively look around the scene, possibly providing a strong sense of presence. Unlike a typical rectangular video that shows only the front view of a scene, gigapixel panoramic video captures omni-directional lights from the surrounding environment. As a counterpart of the image stitching, panoramic video can provide more information and improve the quality of digital entertainment. Panoramic video is also known as a Panoramic Video Loop, in which traditional static photos are replaced by more dynamic representations.

Lastly, drag your ‘VideoRenderTexture’ asset into the Target Texture field. Drag your 360 video file into the Video Clip field and enable ‘Play on Awake’, enable ‘Wait For First Frame’ and enable ‘Loop’. Select this object and, using the Inspector, add the ‘VideoPlayer’ Component. In the hierarchy, Create>New>Empty Object and rename it to ‘VideoObject’. Drag and drop or select the little grey circle to add your ‘VideoSkybox’ material in the top Environment section as the scene’s Skybox Material.Īdd a new object anywhere in your scene. So your assets ‘Video’ folder should look something like this now: Alternatively, you can simply drag and drop the asset onto the square. My video is a top and bottom stereoscopic layout, so I have selected Over Under in the 3D Layout dropdown.įinally, click on the select button in the grey box under Spherical (HDR) and choose your ‘VideoRenderTexture’ asset. Choose Mapping>Latitude Longitude Layout and Image Type>360 Degrees. With the new material asset selected, choose Skybox>Panoramic from the Shader dropdown box in the Inspector. My video, for example, is 2048 x 2304, which is reflected in the size I specified for my corresponding render texture.Ĭreate a new Material in the project panel named ‘Video Skybox’ and move it into your Video folder. This is very important: The size of the render texture must match the size of your video exactly. In the project panel, create a new render texture named ‘VideoRenderTexture’ and move it into the same Video folder. Import your video file as an asset into Unity into a new folder called ‘Video’.
