Abstract
The present invention provides a portable DVR, including a camera, a CPU controller, SD card memory. The camera is connected to the CPU controller by a parellel style, the CPU controller gets a frame picture from the video acquired by the camera, processing by the Retinex method, and recording the processed video to the SD card memory. The invention can acquire vivid human face image information in the monitor information.
Description
Technical field
The present invention relates to a kind of electronic monitoring device, particularly relate to the clear portable digital video register of a kind of superelevation (DVR).
Background technology
Along with the development of electronic monitoring technology, digital video recorder (DVR) series of products are a large amount of has entered market.Advantages such as DVR has that memory capacity is big, definition is high, can monitor in real time, video recording, playback are by the consumer acceptance.
The kernel object of DVR monitoring is the people, and the image that the DVR monitoring obtains is a whole scene.The people is not only very little in the whole scene that DVR monitors, and is also unintelligible; If can not clearly identify human face image information, just not reach monitoring purposes.In addition, traditional DVR supervisory control system is to be fixed on certain position single scene is monitored, and can not carry.
For Portable DVR, the camera that obtains video information connects very crucial.Adopt the USB connected mode to disturb, can not bring into play the advantage of camera fully video signal generating.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of Portable DVR, can obtain human face image information clearly in the image information of monitoring.
For solving the problems of the technologies described above, Portable DVR of the present invention comprises cpu controller, the battery that is connected with cpu controller, camera, PNP USB interface, LCD LCD, LED light-emitting diode, SD card memory, microphone, wave point, keyboard; Wherein, camera and cpu controller adopt parallel mode to be connected, and cpu controller takes out a two field picture in real time from the video record that camera obtains, and adopt the Retinex method to handle, and with the processed video video record in the SD card memory.
Adopt Portable DVR of the present invention,, avoided the loss in vision signal source, almost can realize harmless transmission, improved the antijamming capability of Portable DVR because camera and cpu controller adopt the parallel mode of chip and chip to realize message transmission.
In addition, the present invention applies to face recognition technology can obtain human face image information clearly in the DVR monitoring, and the variation that makes the DVR monitoring produce matter obtains clear Useful Information, reaches the purpose of monitoring.
Portable DVR no longer is confined to the monitoring to fixing point, and the scope of application is more extensive.
Description of drawings
The present invention is further detailed explanation below in conjunction with accompanying drawing and embodiment:
Fig. 1 is a schematic block circuit diagram of the present invention;
Fig. 2 is a control flow chart of the present invention.
Embodiment
As shown in Figure 1, Portable DVR of the present invention comprises a cpu controller, is used to control the work of described Portable DVR, comprises starting recording a video, stop video recording, image processing, message transmission control etc.
Also being included as Portable DVR provides the battery of power supply, the camera that is used to obtain video information that is connected with cpu controller, the PNP USB interface that is used for the transfer of data plug and play, the LCD LCD that is used for displays image information, be used to store the SD card memory of video information, the microphone that can in video recording in real time, record, the wave point of transmission of video and voice data, the LED light-emitting diode (is equivalent to an indicator light, when opening of device, light) by cpu controller control light-emitting diode, the control Portable DVR carries out the keyboard of different operating.Wherein, camera adopts parallel mode to be connected with cpu controller, transmits information in external mode to DVR; Because adopt parallel the connection, transfer of data hardly can be impaired because of data wire length.
Referring to Fig. 2, behind the power supply of unlatching Portable DVR, CUP controller control LED lights automatically.If operation keyboard is selected video recording, then cpu controller starts recording function.Camera obtains video information in real time, and to the cpu controller transmission, begins video recording.Cpu controller is got a two field picture in real time, and a two field picture that extracts is handled with Retinex (a kind of image enchancing method) method, makes it become the superelevation picture rich in detail.The processed video image is stored in the SD card memory.If do not stop video recording,, make whole video recording superelevation clear with regard to each frame video image of circular treatment.Operation keyboard stops video recording, just closes the recording function of whole DVR.
Under the situation of electric power starting, operation keyboard is selected playback, and Portable DVR is according to the playback menu option, but the relevant video recording of select time playback; Suspend playback, can temporarily stop the playback video recording; Select to play, can continue to play the video recording that has been suspended; Stop to pay a return visit, just stop playing back videos.
The memory capacity of Portable DVR of the present invention can be stored 8 hours audio frequency and video video recording continuously.
Claims (1)
1. a Portable DVR comprises cpu controller, the battery that is connected with cpu controller, camera, PNP USB interface, LCD LCD, LED light-emitting diode, SD card memory, microphone, wave point, keyboard; It is characterized in that: camera adopts parallel mode to be connected with cpu controller, cpu controller is from the video record that camera obtains, take out in real time a two field picture, adopt the Retinex method to handle, and with the processed video video record in the SD card memory.
