This paper introduces the design and implementation measures of the network video surveillance system based on embedded system. This system chooses S3C2440 which based on ARM9 architecture as an embedded processor and uses the stable and efficient Linux system as its operating system. Based on the ordinary remote network video surveillance system, a new algorithm for detecting moving abject is added,...
To reduce the manpower and response time for surveillance systems at low cost, in this paper, an ARM-based embedded system dedicated for unattended realtime moving target detection is constructed. The comprehensive procedures in building up an embedded system such as setup environment for cross-compilation, migration of Bootloader, migration of Linux-2.6 kernel, fabrication and migration of root document...
Embedded systems are being further developed and applied in medical devices. In this paper, we present an embedded design for dental intraoral system which supports dental image capturing and image tooth segmentation. This device assists dentists in diagnosis by using dental images, which is captured from dental camera. Moreover, we propose advanced features for the dental intraoral system including...
The hardware and software realization of a network video monitoring system was presented. A S3C2410 processor was used as the core of the embedded video server. The embedded video capturing software was developed according to V4L(video for linux) specification. The real time JPEG video stream was then transmitted from the server to the remote PC client through a socket connection. The system showed...
With the current commodity marker's counterfeits and inferior phenomenon, this paper presents a design of portable instrument for detecting trademark with digital watermark. The hardware structure of this detecting instrument is centering in S3C241 microprocessor, expanding peripheral interface, such as USB, human-computer interaction and so on. Detection software chooses a combination of DCT (Discrete...
In order to achieve the purpose of cross-platform remote monitoring simply and conveniently, this paper has done a research on a remote real-time monitoring system accessed by browsers. A web server is established successfully in the embedded Linux operating system, which takes ARM-processor S3C2440 as the core of hardware. Users can monitor remote temperature, humidity and video information only...
Based on ARM9 platform and the Linux operating system, this article studied on the methods of the video image capture and decoding. Take USB-camera image acquisition and image decoding for example, FrameBuffer and Video4Linux, two system interfaces for video image processing under the Linux operating system are introduced, and the collected images transferred from JPEG format to RGB format is displayed...
Recognizing a specific moving target and capturing image with its trajectory has a wide range of applications. This paper introduces an embedded network video device system scheme which is used for target tracking and it is based on FPAG, ARM and Embedded Linux OS. The embedded network device consists of three main parts: image acquisition, image transmission, image processing included image recognition...
This paper introduces a smart home security system based on the technology of ARM9 and 3G communication. It uses S3C2410 hardware platform and embedded Linux operating system to implement the real-time display of the video images on the development platform. It presents the structure and work principles of the system, puts emphasis on the hardware processing circuits and design of video image software...
Image acquisition and transmission is indispensable component in monitoring system and many entertainment devices. An image data collection and transmission system based on ARM (advanced RISC machines) is presented in this paper. The hardware architecture of the system is designed, ARM9 core S3C2410 chip was used as the kernel control unit of this system, USB interface mode is used to connect the...
