Abstract
As a variety of video surveillance devices such as CCTV, drones, and car dashboard cameras have become popular, numerous studies have been conducted regarding the effective enforcement of security and surveillance based on video analysis. In particular, in car-related surveillance, car tracking is the most challenging task. One early approach to accomplish such a task was to analyze frames from different video sources separately. Considering the shooting range of the bulk of video devices, the outcome from the analysis of single video source is highly limited. To obtain more comprehensive information for car tacking, a set of video sources should be considered together and the relevant information should be integrated according to spatial and temporal constraints. Therefore, in this study, we propose a real-time car tracking system based on surveillance videos from diverse devices including CCTV, dashboard cameras, and drones. For scalability and fault tolerance, our system is built on a distributed processing framework and comprises a Frame Distributor, a Feature Extractor, and an Information Manager. The Frame Distributor is responsible for distributing the video frames from various devices to the processing nodes. The Feature Extractor extracts principal vehicle features such as plate number, location, and time from each frame. The Information Manager stores all the features into a database and handles user requests by collecting relevant information from the feature database. To illustrate the effectiveness of our proposed system, we implemented a prototype system and performed a number of experiments. We report some of the results.
Highlights
With the rapid advancement of IT technology, a number of video surveillance devices have entered a wide use for surveillance and security purposes in daily life
In this study, based on these investigations, we propose a real-time car tracking system Integrated video-based automobile tracking system (IVATS) that can collect video big data, extract and store principal vehicle features, and process user queries in a real-time environment
3 Methods In this chapter, we describe the overall structure of our IVATS for real-time car tracking in detail
Summary
With the rapid advancement of IT technology, a number of video surveillance devices have entered a wide use for surveillance and security purposes in daily life. As a typical example, closed-circuit television (CCTV), known as video surveillance, uses video cameras to transmit video signals to a limited set of monitors. Because of improved definition, better distribution rates, and various basic functions of CCTV, more diverse applications have become implemented [1, 2]. Another popular example is the dashboard camera, car DVR or car black box, that is one or a pair of onboard cameras that continuously record (loop recording) the view through the windscreen. Dashboard cameras can provide video evidence in the event of a road accident or
