Multiple View Video Streaming and 3d Scene Reconstruction for Traffic Surveillance
نویسندگان
چکیده
We present a 3D modeling system for traffic surveillance applications. The application contains several cameras positioned around a traffic scene. The video signals are compressed and streamed to a central client. At the central client a scene reconstruction is carried out, using all 2D camera views utilizing 3D camera calibration information. To combine all views into a 3D model, moving objects are separated from static background first. Then a geometric model is built for the background. Foreground objects are modeled exploiting database objects. The appropriate textures are taken from the camera views and combined to form a multi-texture surface. Finally, lighting and view-dependent interpolation is carried out on the graphics card.

Traffic Scene Analysis using Hierarchical Sparse Topical Coding
Analyzing motion patterns in traffic videos can be exploited directly to generate high-level descriptions of the video contents. Such descriptions may further be employed in different traffic applications such as traffic phase detection and abnormal event detection. One of the most recent and successful unsupervised methods for complex traffic scene analysis is based on topic models. In this pa...
متن کاملFlexible Human Behavior Analysis Framework for Video Surveillance Applications
We study a flexible framework for semantic analysis of human motion from surveillance video. Successful trajectory estimation and human-body modeling facilitate the semantic analysis of human activities in video sequences. Although human motion is widely investigated, we have extended such research in three aspects. By adding a second camera, not only more reliable behavior analysis is possible...

In recent years, the convergence of computer vision and computer graphics has put forth new research areas that work on scene reconstruction from and analysis of multi-view video footage. In free-viewpoint video, for example, new views of a scene are generated from an arbitrary viewpoint in real-time using a set of multi-view video streams as inputs. The analysis of real-world scenes from multi...

3D-video systems allow a user to perceive depth in the viewed scene and to display the scene from arbitrary viewpoints interactively and on-demand. This paper presents a prototype implementation of a 3D-video streaming system using an IP network. The architecture of our streaming system is layered, where each information layer conveys a single coded video signal or coded scene-description data....

3D Tele-immersion (3DTI) technology allows full-body, multi-modal content delivery among geographically dispersed users. In 3DTI, user’s 3D model will be captured by multiple RGB-D (color plus depth) cameras surrounding user’s body. In addition, various sensors (e.g., motion sensors, medical sensors, wearable gaming consoles, etc.) specified by the application will be included to deliver a mult...
