The 8th International Conference on 3D Vision was virtually held on November 25-28, 2020. In 2011, 3DIM and 3DPVT joined forces to create a new yearly conference dedicated to 3D research, originally known as 3DIMPVT for 2011 and 2012. Since 2013, under the name 3DV (3D Vision), this event has provided a premier platform for disseminating research results covering a broad variety of topics in the area of 3D research in computer vision and graphics, from novel optical sensors, signal processing, geometric modeling, representation and transmission, to visualization and interaction, and a variety of applications. 3DV 2020 will showcase high quality single-track oral and poster presentations and demonstration sessions. It will also feature industrial exhibitions held in conjunction with the main conference. Proposals for Tutorials and Demos are also invited. Accepted papers will be published by Conference Publishing Services (CPS) and submitted to IEEE Xplore and CSDL.
