The display device 800 may be implemented as a display device such as a liquid crystal display (LCD).

The operation of the forensic evidence photographing system removing the contaminant according to the present invention configured as described above will now be described in detail.

First, the recording reproduction image generation means 100 and the evidence image acquisition means 400 are installed at a predetermined position of the evidence collection chamber 2.

Thereafter, the investigator puts the evidence (1) on the evidence seating table (10) and starts photographing or collecting the evidence (1).

Here, the recording reproduction image generating means 100 may use a video camera (for example, a CCTV camera) and the like, and the evidence (1) at a distance such that the video capture means 400 is not restricted by video shooting. And it is preferable to install in the seat 10 to be separated in space, to minimize the errors of the evidence obtained by removing the contaminants of the evidence collection sample to improve the quality of the evidence acquisition and accuracy. The recording reproduction image generating means 100 may install a post 120 on the ceiling of the evidence collecting chamber 2 and may be installed at a lower end of the post 120.

The recording reproduction image generating means 100 installed in the evidence collection room 2 captures the entire process of the evidence collection of the tester through the video photographing unit 110 as a video. In this case, the captured video may be photographed in conjunction with the evidence flow. The video photographed by the video photographing unit 110 is processed by the video processing unit 130 using a general video processing technique, and the recorded video image storing means 300 records the video recorded through the communication module as a real-time streaming image through the communication network 200. ). If the real-time streaming video is stored as it is, the memory requirement increases, it is preferable to compress and store using a video compression method.

In the evidence collection room 2 as described above, the tester is photographed of the evidence image and the whole process of taking the evidence is taken.

In addition, the investigator photographs the evidence 1 through the evidence image acquisition means 400 to obtain an evidence image.

Here, as shown in FIG. 3, the evidence 1 is photographed while being mounted on the evidence seat 10. At this time, the evidence image acquiring means 400 is a rotation part 460 free of angle adjustment and vertical movement. It is free to move, and it is very convenient to photograph the evidence (1).

For example, in the state where the evidence 1 is placed on the evidence seat 10 as shown in the left side of FIG. 3, the evidence 1 is placed in a state where the evidence image acquiring means 400 is positioned at a predetermined height (for example, 80 cm). To shoot. In addition, when changing the position of the evidence (1) or when photographing the evidence at a lower position, by moving the rotating unit 460 manually the evidence image acquisition means 400 is moved to a low height (for example, 40cm) Photograph the evidence (1).

Here, the rotating part 460 is made of a multi-joint manipulator (Manipulator), one end is supported by the support 450 to the post 440 fixed to the ceiling, the recording device (photo taking part) 410 mounted at the end is According to the manual manual manipulation of the tester, the articulated manipulator rotates freely, changes the angle, and photographs the evidence (1) while moving up and down.

In the present invention, the evidence image acquisition means 400 is described as manually photographed by the tester to photograph the evidence (1), the present invention is not limited to this, the evidence (1) automatically by a preset automatic program It is also possible to shoot).

For example, according to the order of acquiring the image of the evidence, the image acquisition means 400 automatically controls the amount of rotation to control the angle, and controls the height by adjusting the height of the upper and lower sides, thereby obtaining the evidence image (photo, image). can do. In this case, the automatic program may predetermine the order of acquiring the evidence image from the evidence. To this end, it is assumed that the evidence image acquiring means 400 includes a control unit for controlling the rotating unit 460 according to an automatic program, and a driving unit including a motor for operating the rotating unit under control of the control unit.

In the process of acquiring the evidence 1 image, the examiner inputs recording information (label information, photographing date and time information, photographing sequence information, evidence location information, etc.) through a separate input device. The input record information is preferably mapped and stored with the evidence image information acquired by the evidence image acquisition means 400.

The evidence image acquisition means 400 acquires a photograph (image) by photographing the evidence in the photographing unit 410 when photographing the evidence starts. The photograph information acquired by the photographing unit 410 is processed by the photographic image processing unit 430 through a general image processing technique, and then transmitted to the evidence image storing means 500 through the communication module. The evidence image storing means 500 also includes a communication module, and receives the evidence image transmitted through the communication network 200 and stores the evidence image in the internal storage device. Here, the communication network 200 may use a local area network such as Bluetooth, Wi-Fi, a low power long range wireless communication network such as LoRa, a CDMA network, an LTE network, or the like.

Here, the lighting means 600 provides illumination for obtaining evidence images and recording and reproducing image information in the evidence collection room 2. LED lighting is usually used for photographing evidence. These LED lights only provide the brightness of the brightness for photographing the evidence, but it is impossible to indicate blood or semen from the evidence. Therefore, the present invention may additionally irradiate the evidence 1 with a laser beam or a law light source to accurately photograph the corresponding position while instructing blood or semen on the evidence.

On the other hand, as another feature of the present invention, the recording and reproducing image information obtained and stored in the same process as described above, in the state of obtaining and storing the evidence image, whether the tester performed the evidence image recording later, whether the information input is correct Can be verified.

It is very important here to verify the evidence status of the investigator after the evidence collection and the behavior of the investigator when the evidence is collected. Labeling errors or errors in recording will cause a great deal of trouble later in verifying the integrity of the evidence. Previously, there was no method for verifying the evidence state and the behavior of the collecting investigator when collecting evidence, and only a primitive method was performed by the investigator himself or another person to view and judge the evidence photographing information with the naked eye.

Therefore, the present invention implements a complete dynamic record reproduction for the evidence control when the examiner collects evidence, thereby enabling the correction of missing and misleading records, and more clearly the restoration of the evidence state.

For example, the evidence collection verification means 700 compares the dynamic record reproduction information stored in the record reproduction image storage means 300 with the record information and evidence flow information of the evidence image stored in the evidence image storage means 500 to collect evidence. Validate tester behavior throughout the process. Here, the evidence collection verification means 700 may use a device such as a computer including a control program.

The evidence collection verification means 700 is interlocked with the record reproduction image generation means 100, the evidence image acquisition means 400, and the display device 800, and records information of the record reproduction image and the evidence image according to the evidence flow. The balance is verified, labeling, evidence flow error is verified, and the verification result is displayed on the display device 800. 4 illustrates an example of a verification result screen displayed on the display device 800.

Here, the evidence collection verification means 700 simultaneously records the record reproduction image and the record information of the evidence image through the divided screens of the record reproduction image display unit 810 and the evidence image display unit 820 of the display device 800 according to the evidence flow. It is also possible to make it easy for the investigator to identify it.

Therefore, this verification means allows the investigator or verifier to easily and clearly verify that the evidence collection process is normal and that the evidence collection information and record information match.

If necessary, if a record is missing or a label is found, it may be displayed through the display device 800 so that the examiner or the checker can easily recognize the error part. The error display method may be a method of displaying a message in which an error is found through a screen of a computer, or directly displaying an error portion in an evidence image.
