Video surveillance has important role in the security system.In order to improve the intelligence level of video surveillance systems,we design and implement a Cortex-A8-based smart video sensor.First,we built the hardware platform for video sensor,which uses s5pv21 0 as processing core,TVP51 50 as video capture module,power supply,Ethernet port,serial port and other external auxiliary circuits as bases;then,taking embedded Linux as the system platform,we decode video with TVP51 50,and compress video with built-in MFC of Cortex-A8.Based on the ViBe algorithm we achieve regional alert and smoke detection,etc;finally,we integrate hardware and software as a whole,and realise the design of smart video sensor.Experiments show that the design improves the real-time property and accuracy of detection alarm and intelligent recognition in smart video surveillance system.
