Abstract
The utility model relates to a video processing board comprising an ARM926EJ-S chip, a video processing subsystem, an MJCP coprocessor, an HDVICP coprocessor, an SD card storage unit, a crystal oscillator, external data interfaces, and a debugging port. The external data interfaces include a serial port, a parallel port, and a usb port; the serial port is connected to an upper computer and is used for receiving an instruction from the upper computer; and the parallel port connected to a keyboard is used for responding to an operation of a manipulator. An thermal infrared imager and a television recording instrument provide input videos for the video processing subsystem; and a monitoring device is used for displaying the videos processed by the video processing subsystem. The provided video processing board has advantages of fast speed, clear and coherent image, capability of supporting various image formats, high cost performance, and high practicability.
Description
Technical field
The utility model relates to a kind of Video processing plate, can classify to vision signal, information stack, record and playback.
Background technology
Along with science and technology and the development of information technology, video processing technique is develop rapidly also, is widely used, and when gun aim at, needs a kind of Video processing plate, visual for realizing aiming, is more conducive to school rifle.Be difficult to support multiple picture format.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of Video processing plate.
The technical scheme in the invention for solving the technical problem is: it is by ARM926EJ-S chip, video processing subsystem, MJCP coprocessor, HDVICP coprocessor, the storage of SD card, crystal oscillator, external data interface, debug port composition, wherein external data interface has serial ports, parallel port and usb mouth, serial ports is used for connecting host computer, receive the instruction of host computer, parallel port is used for connecting keyboard, operation response manual manipulation, thermal infrared imager and telerecording instrument provide input video for video processing subsystem, monitor is for showing video processing subsystem video after treatment.
The utility model speed is fast, and clear picture is coherent, supports multiple picture format, and cost performance is high, practical.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, Video processing plate adopts Leonardo da Vinci's high-performance multimedia processor finishing equipment management of Texas Instrument (TI), compression processing and the transport communication of video.The new digital Media Processor towards the application of portable HD video based on Davinci technology (DaVinciTM technology) that TI releases is an integrated ARM kernel, H.264 high definition encoding and decoding coprocessor HDVICP and a MPEG-4/JPEG high definition encoding and decoding coprocessor MJCP, can support HD video encoding and decoding H.264/MPEG-4.In master chip, ARM kernel, as master controller, is the 32bit RSIC instruction set that adopts channelization streamline, has the feature of low power consumption high efficiency.Master controller is carried out common system control task, as system initialization, and configuration, power management, user interface and user command etc.ARM is as master control and to carry out these functions be because it has a large program's memory space and task switching capability fast, thereby it is more suitable for complexity, multitask and general task control.
Video processing plate is made up of ARM926EJ-S chip, video processing subsystem, MJCP coprocessor, HDVICP coprocessor, the storage of SD card, crystal oscillator, external data interface, debug port, and composition frame chart is shown in Fig. 1.Wherein external data interface has serial ports, parallel port and usb mouth, and serial ports is used for connecting host computer, receives the instruction of host computer, and parallel port is used for connecting keyboard, operation response manual manipulation.Thermal infrared imager and telerecording instrument provide input video for video processing subsystem, and monitor is for showing video processing subsystem video after treatment.
Video processing plate can carry out compressed encoding to the two-way information collecting, format conversion, can normally show at monitor output, can also process the state information, operation bench data of input and manipulation instruction, to these signals classify, video record playback.
Video processing plate adopts (SuSE) Linux OS, and all output images that require are developed under embedded image development environment.
The code of software development is succinct, efficient, and ensures readability and the encapsulation property of code, to ensure in the time that logic is adjusted, can adjust software section fast.
