A workflow for Web3D interactive outdoor scene visualisation
Yash J. Vyas, Emily Campbell, Stuart Anderson, Matt Adcock · 2017
In this paper, we present a workflow to create Web3D interface that allows users to interact with video footage of outdoor scenery as a 3D reconstructed scene. Video clips of an outdoor scene are processed through a matchmoving and photogrammetry program, and solved for camera paths in a globally oriented coordinate frame. A three.js web app uses these paths to create a Web3D visualisation that projects objects added in the 3D scene on top of their locations in the original 2D video background. These objects move as the video frames are scrubbed, in accordance with their correct spatial locations within the visual scene. The visualisation script is a template that can be used to compile any visualisation through changing the camera paths and associated video clips. These camera paths can be obtained by using photogrammetry tools to process the desired set of videos.
