Description
Technical field
The present invention relates to the digitized video technical field, specifically is a kind of being applied in the judicial evidence collection, has the digitized video filming apparatus of space time information and primitiveness sign.
Background technology
Present filming image instrument mainly contains two kinds: the one, and traditional with the traditional filming image equipment of film as the imaging photosensitive carrier, as film camera; Another kind is with CCD or the CMOS digitized video camera-shooting and recording device as the imaging photosensitive original paper, as digital camera, Digital Video.Along with the propelled at high velocity of global IT application process, digitizer is used day by day and is popularized, and digitizer is easy to use because having, with low cost, be convenient to directly incorporate advantage such as digital communications network, replaced traditional analog equipment at numerous areas.
Present judicial evidence collection field, digitized video camera-shooting and recording device have replaced conventional film formula filming image equipment substantially, and the digitized video camera-shooting and recording device has advantages such as cost is low, convenient and swift, and work has brought facility to judicial evidence collection.But the electronic data that existing digitized video camera-shooting and recording device is shot with video-corder, common characteristics with electronic data, its essence are one group of Binary Zero 1 codes, revise easily or damage, in judicial evidence collection work, the people distorts or the equipment operation troubles all can cause differing from the consequence of original true partial data; Though the electronic data that the digitized video camera-shooting and recording device that adopt in existing judicial evidence collection field produces can be by the completeness check algorithm in later stage, calculate its integrity check value, to guarantee the uniqueness of this document, whether identification is modified, but it can only differentiate whether the electronic data that carries out completeness check computing front and back is consistent, can not illustrate whether the electronic data that participates in integrity operations is distorted or damaged; The electronic data that the digitized video camera-shooting and recording device that adopt in existing judicial evidence collection field produces does not have objective time mark, the free record of part capture apparatus, but the time from the clock system of equipment self, accuracy can not get guaranteeing, as evidence obtaining equipment, its time does not more possess convincingness; The electronic data that the digitized video camera-shooting and recording device that adopt in existing judicial evidence collection field produces does not have free token, the three dimensional space coordinate in the time of can not taking electronic data from the objective sign of technological layer.
In the judicial evidence collection field, the electronic evidence that above-mentioned deficiency causes existing digitized video camera-shooting and recording device to produce is easily renderd a service low, and evidence obtaining is the result also queried easily, therefore brought inconvenience to judicial evidence collection.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides a kind of digitized video filming apparatus with space time information and primitiveness sign, the digitized video that this device is taken has time, spatial information, be provided with the completeness check module, guarantee the captured electronic data file of this device be original, true, complete, do not distorted.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of digitized video filming apparatus with space time information and primitiveness sign, comprise master cpu, it is characterized in that: described master cpu is connected with display, holder, the GPS module, optical lens, described optical lens connects the CCD/CMOS photoelectric sensor, the CCD/CMOS photoelectric sensor connects analogue signal processor, analogue signal processor connects A/D converter, A/D converter connects the DSP digital signal processor, the DSP digital signal processor is connected with the completeness check module, the completeness check module respectively with the GPS module, holder connects, and described holder is connected with display.
During use, master cpu control optical lens, the light of subject reflection is transmitted on the CCD/CMOS photoelectric sensor by optical lens, the photodiode of CCD/CMOS photoelectric sensor is subjected to exciting of light and discharges electric charge, generate the signal of telecommunication of photo-sensitive cell, the control chip of CCD/CMOS photoelectric sensor utilizes the control signal circuit in the photo-sensitive cell that the electric current that light-emitting diode produces is controlled, exported by the current delivery circuit, the CCD/CMOS photoelectric sensor can collect the signal of telecommunication of Polaroid generation, unified outputing to amplified in the analogue signal processor and filtering, be sent to A/D converter through amplification and the filtered signal of telecommunication, by A/D converter the signal of telecommunication (analog signal) is converted to digital signal, the size of numerical value, the intensity of the signal of telecommunication is directly proportional with the height of voltage, these numerical value are the data of image just in fact, these digital signals are sent to the DSP digital signal processor again, the DSP digital signal processor carries out colour correction to these image datas, white balance is handled, and is compiled as the form that digital filming equipment is supported, the image file of resolution; The GPS of master cpu control simultaneously module, the time that the GPS module will collect in the time of will taking, spatial information append in the image file that the DSP digital signal processor is compiled into, and these times, spatial information comprise temporal information, longitude and latitude, the absolute altitude of satellite clock source calibration; Image file carries out completeness check and calculates in the completeness check module, and the corresponding integrity check value of output, can adopt MD5, SHA1, SHA2 scheduling algorithm at present, last under the control of master cpu, the image file with space time information that calculates through completeness check send and stores in the holder and show in display.
The invention has the beneficial effects as follows: the captured digitized video of the present invention has time, spatial information, carrying out completeness check in the process of taking calculates, export integrity check value synchronously with shooting results, guaranteed primitiveness, authenticity, the integrality of electronic data file.
