Virtual Exploration in a City -- Renovation of Movie Map

 

Abstract: In this talk, we introduces our work on a Movie Map, which will enable users to explore a given city area using 360 degree videos. Visual exploration of a city is always needed. Nowadays, we are familiar with Google Street View (GSV) that is an interactive visual map. Despite the wide use of GSV, it provides sparse images of streets, which often confuses users and lowers user satisfaction. Forty years ago, a video-based interactive map was created -- it is well-known as Aspen Movie Map. Movie Map uses videos instead of sparse images and improves the user experience dramatically. However, Aspen Movie Map was based on analog technology with a huge effort and never built again. Thus, we renovate the Movie Map using state-of-the-art technology. We build a new Movie Map system with an interface for exploring cities. Using 360 videos captured along streets in a certain area of a city, we can build an interactive Movie Map -- dividing videos into segments by intersections, synthesizing turning views.   
 

By connecting the video segments following the specified movement in an area, we can watch a walking view along a street. We demonstrate the system in the talk.
