smart camera for traffic surveillance - rahul4388 - 10-04-2017 [attachment=5387] SMART CAMERA FOR TRAFFIC SURVEILLANCE PRESENTED BY ADARSH VIMAL.B ROLL NO:2 S7 CS INTRODUCTION Smart camera- integration of advanced image sensors and high performance processors. Must be implemented as an embedded system. Mounted in tunnels and aside highways. Electric power supplied by power socket or solar panels. Smart camera delivers better video quality and video analysis results. Captures images and videos and processes them. Transfers the video stream via a network. Offer flexible video transmission. REQUIREMENTS Smart camera is comprised of Sensor Processing unit Communication unit Sensor requirements High dynamic range and little blur High resolution Maximum frame rate CMOS sensor Processing requirements Video compression Video analysis Computation of traffic statistics Camera control and firmware Video compression Video should be compressed. Video analysis Extracts an abstract scene from the raw data. If any situation detected, alarm is triggered. Computation of traffic statistics Computed out of video stream. Camera control and firmware Control aperture and flash control and the firmware. Communication requirements Compressed video and video analysis are transferred to control station. Besides data upload it should also support data download. System requirements Low power consumption Low heat dissipation Timing constraints should be correct. ARCHITECTURE Divided into three parts Video sensor Processing unit Communication unit Video sensor First stage in overall data flow. CMOS sensor is used. Processing unit Second stage in overall data flow. Performance requirements are fulfilled with digital signal processors(DSP) which are loosely coupled. Each processor connected to its own local memory. DSP s external memory capacity between 8mb and 256mb. Communication unit Final stage in overall data flow. Processing unit transfers data to the communication unit via generic interface. Flashes, pan-tilt zoom heads and dome are controlled by this unit. Low power considerations Dynamic power management(DPM) Individual components can be switched to different power modes during runtime. The commands to change the components power modes are issued by a central Power Manager (PM). In order to decide which command to issue the PM must have knowledge about the system s workload. In the smart camera the PM is located in the OS kernel of the host DSP. Characteristics are stored in look-up-tables in the PM and are used as input for the PMP. SOFTWARE The software architecture of the smart camera is basically divided into two parts: DSP s are configured basically to run computation tasks. XScale processor is primarily used for system control and communication purposes. Video compression The advanced simple profile MPEG-4 encoding method is well-suited for traffic surveillance. The smart camera uses HTTP to provide a flexible and user-friendly user interface. UDP is used for multicast streaming-video transmission. Network connection Internet connections require the TCP/IP protocol implemented as an IP stack. Uses protocols HTTP,FTP and UDP. Firmware The smart camera s firmware controls the overall system behavior, and provides interfaces and methods for different tasks . Four basic run levels are defined by the firmware: The normal mode The alarm mode The full update mode The partial update mode Normal mode Video compression running quality is low. Alarm mode Enters this mode when an alarm mode is detected. Quality of video stream is increased. Full update mode Used when the firmware is updated. Partial update mode Activated when a task has to be re-placed or removed from the smart camera. ADVANTAGES Low power consumption. Flexible video transmission. Noise in the video data is reduced by video computation. Less expensive. Smart camera is fully integrated, simple and reliable. DISADVANTAGES Smart camera solutions are not flexible Usually provide limited user interface. APPLICATIONS Video motion detection Detects a change in the video. Built-in filters ignore camera vibrations and areas with constant motion. User can define object properties and for some intrusion detection situations direction. Static Object Detection Offers the ability to analyze and track static (stationary) objects. An advanced Non-isolated Object filter is useful in dynamic, congested settings. Other applications are: Motion analysis Facial identification Video surveillance for large complexes. Video conferencing Store/Business Surveillance - Theft Prevention/Curtailment Door Entrance Monitoring/Video Intercoms Observing unsupervised facility / factory. FUTURE SCOPE Smart camera technology will begin to enter new applications. Applications include security and access control markets. In the automotive industry. For collision avoidance, and even one day for the toy industry. Even our automobiles may soon be outfitted with miniature eyes. CONCLUSION The smart camera integrates a CMOS image sensor, a processing unit featuring two high performance DSP s and a network interface. It senses and analysis the video and transfers the computed information via network, thus managing the traffic effectively. Advances in performance and integration will enable new and more functionality implemented in smart camera. smart camera for traffic surveillance - viswanath - 10-04-2017 Abstract The integration of advanced CMOS image sensors with high-performance processors into an embedded system facilitates new application classes such as smart cameras. A smart camera combines video sensing, video processing and communication within a single device. This paper reports on the prototype implementation of a smart camera for traf c surveillance. It captures a video stream, computes traf c information and transfers the compressed video stream and the traf c information to a network node. The achieved experimental results of the implemented stationary vehicle detection demonstrate the feasibility of our approach. smart camera for traffic surveillance - jabeena banu - 10-04-2017 hello, iam a 4th year engineering student,branch computer science.. 8th july iam having a seminar on the topic "smart camera for traffic surveillance".. i need the full report and a powerpoint presentation of this topic urgently..since it is on 8th i kindly request you to post the full report and ppt at the earliest.. thanking you.. smart camera for traffic surveillance - harsh raj rastogi - 10-04-2017 More Info About smart camera for traffic surveillance http://seminarsprojects.net/Thread-smart-camera-for-traffic-surveillance http://vmars.tuwien.ac.at/wises/papers/12_A_smart_traffic_camera_for_stationary_vehicle_detection.pdf smart camera for traffic surveillance - nagu - 10-04-2017 hello, i am a 4th year engineering student,branch computer science.. my seminar on the topic "smart camera for traffic surveillance".. i need the full report and a powerpoint presentation of this topic urgently.. smart camera for traffic surveillance - jeffin.s.nicholas - 10-04-2017 sir, i need full seminar report on "smart camera for traffic surveillance".. please make it as soon as possible.. |
