Description

TECHNICAL FIELD [0001] The present invention relates to a train simulator device, a train simulator providing method, and a recording medium therefor.

The present invention relates to a train simulator device, a train simulator providing method, and a recording medium thereof, which are used for train driving practice of an engineer. More particularly, the present invention relates to a train simulator, A train simulator device for determining a reproduction speed, a method for providing a train simulator, and a recording medium therefor.

2. Description of the Related Art Conventionally, two methods of displaying a line image used in a train simulator have been mainly used, namely, a Motion Joint Photographic Coding Experts Group (MJPEG) method and a 3D modeling method.

MJPEG is a technology that was mainly used before the 1990s. It takes pictures at a certain distance while traveling on a line section of a train at a constant speed, and when photographed picture data is used in a train simulator, And the speed is adjusted to reproduce on the driver's screen.

However, such a MJPEG method has a low screen resolution of about 640 x 480 pixels, which is disadvantageous in that the quality is low and the driver's feeling of immersion is small when projected on a large screen, and the amount of data to be processed is high And the need to get special hardware support. In addition, the MJPEG method has the problem that the image is disconnected when the driver's screen is slow to reproduce, for example, when the trains of the train simulator are slow (for example, when entering the station) due to the limitation of data stored at 30 frames per second There is a problem in that the time interval of the photographic data must be made constant through a lot of editing processes even after shooting because the train can not be driven at a constant speed when shooting the line section. For example, in the case of a train simulator manufactured by MARCONI Corporation, since the interval per frame is at least 35 cm, there is a problem that when the train of the train simulator travels at 35 cm / Frame or less, the image is disconnected.

The 3D modeling method has been widely used since the 2000s when the hardware performance of the computer CPU and the VGA rapidly developed and the 3D virtual reality production tool appeared. The 3D modeling method is a method of modeling the surroundings of the actual train- It is a method of projecting the reality onto the driver's screen after producing it. FIG. 1 shows a line image production process of a train simulator using the conventional 3D modeling method.

However, such a 3D modeling method also requires a lot of manpower and cost to make the real world around the track into a 3D virtual reality world because the user visually confirms the moving image data of the actual track and performs the 3D modeling work In particular, it is difficult to accurately express the size and position of surrounding backgrounds or line structures.

That is, a trainer using a train simulator learns the track of the training section and receives the acceleration / deceleration control train of the train with reference to milestones around the track, for example, a signal or a train number. The virtual line images of the present invention have been produced in a similar manner to the actual lines because of the above-described practical difficulties. Therefore, the accuracy of the 3D virtual reality images used in the train simulator is very different from the actual operating line environment, which is suitable for the basic operation skill training, but it is very insufficient for the actual operation training course for actual engineers. However, even though Korea has a driver license for the trains of the Ministry of Land, Transport and Maritime Affairs, the trainees of the Korea Railroad Corporation can obtain the license for the section of the railway line to be operated. The reason for this is that if the train driver's license is a license for basic train operation skills and crisis coping ability, then the track section license must know the train track information, the signal train and other peripheral information to operate and secure a safe train operation environment. It is because it guarantees that it can be.

Accordingly, there is a need for a train simulator capable of solving the problems of the conventional MJPEG method and the 3D modeling method as described above, while providing the same line image as the actual line section.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like reference symbols in the drawings denote like elements.

2 is a view showing a train simulator device according to an embodiment of the present invention. 2, the train simulator device 200 according to an embodiment of the present invention may include a line image database unit 201, a simulator control unit 202, and a display unit 203. 2, the train simulator device 200 according to an embodiment of the present invention may further include a virtual frame generation unit 204, an interface unit 205, and a wired / wireless communication unit 206 have.

The line image database unit 201 may be implemented by various types of data storage devices and may include at least one frame image generated by recording a line image and reproduction speed reference information corresponding to each of the at least one frame image The line video data can be stored. As an example, the at least one frame images may be a photographic image constituting a line image, and at least one frame image may be continuously displayed on the display unit 203 to reproduce the line image. The reproduction speed reference information included in the line image data may include at least one of traveling speed information of a train at the moment of recording the line image and traveling distance information of the train at the moment of recording the line image.

The line video data is installed in a train running on a real line section to record the line video and measures at least one of a traveling speed and a traveling distance of a train traveling in a line section at the moment the line video is recorded, Or may be generated by the line video recording apparatus 300 that stores the video data in the additional metadata area and may be stored in the line video database unit 201. The line video recording apparatus 300 will be described in detail with reference to FIG. 3, and a detailed description thereof will be omitted here.

The simulator control unit 202 determines the line image reproduction speed by comparing the reproduction speed reference information corresponding to the frame image under image reproduction with the train running speed and outputs the line image reproduction speed and the line image reproduction corresponding to the line image data And outputs the generated signal to the display unit 203.

Here, the train running speed may mean a running speed of a train displayed on the display unit 203 by the train simulator device 200 according to an embodiment of the present invention. As an example, the train running speed may be changed by a user's operation (e.g., acceleration or deceleration) input through the interface unit 205. [ In addition, as described above, the reproduction speed reference information may include at least one of the traveling speed information and the traveling distance information, and the traveling speed information may include at least one of a traveling speed of a train traveling in a line section at the moment of recording the frame image And the travel distance information may mean the distance traveled from the starting point of the train traveling in the line segment at the moment of recording the corresponding frame image.

First, assuming that the reproduction speed reference information includes the traveling speed information, the simulator control unit 202 compares the traveling speed information corresponding to the frame image under image reproduction with the train traveling speed, The line video reproduction speed can be determined.

Figure 112013013384108-pat00001

For example, when the traveling speed (traveling speed of the current frame) corresponding to the frame image under image reproduction is 60 km / h, the train operation of the virtual train reproduced by the train simulator device 200 according to the embodiment of the present invention When the speed is 90 km / h, the line image reproduction speed may be 1.5 times (= 90/60) of the reference reproduction speed. Accordingly, in this case, the simulator control unit 202 can set the line image reproduction speed to reproduce the line image data at 1.5 times the reference reproduction speed, and output the line image reproduction signal to the display unit 203. [ Accordingly, the display unit 203 can reproduce the line video data at 1.5 times the reference reproduction speed. Here, the reference reproduction speed may mean a reproduction speed when the line video data is reproduced at the same speed as the recording speed set when the line video data is recorded.

Next, assuming that the reproduction speed reference information includes the traveling distance information, the simulator control unit 202 sets the traveling distance information corresponding to the frame image being reproduced as the image corresponding to the next frame image of the frame image being reproduced The traveling speed information extracted in comparison with the traveling distance information is compared with the traveling speed of the train, and the traveling speed of the line image can be determined as shown in Equation (2) below.

Figure 112013013384108-pat00002

For example, when the line image data is recorded and stored at 60 frames per second and the running distance (running distance of the current frame) corresponding to the frame image being reproduced is 20,000 cm, corresponding to the next frame image of the frame image being reproduced If the traveling distance (traveling distance of the next frame) is 20,025 cm and the traveling speed of the train reproduced by the train simulator device 200 according to the embodiment of the present invention is 108 km / h, The running distance of the current frame) is 25 cm, and the time difference between frames is 1/60 second, the running speed of the current frame may be 25 X 60 X 60 X 60 = 54 km / h. Therefore, the line video reproduction speed can be twice (= 108/54) the reference reproduction speed. Accordingly, in this case, the simulator control unit 202 can set the line image reproduction speed to reproduce the line image data at twice the reference reproduction speed, and output the line image reproduction signal to the display unit 203. [ Accordingly, the display unit 203 can reproduce the line video data at twice the reference reproduction speed.

That is, the simulator control unit 202 calculates and regulates the reproduction speed of the line video data stored in the line video database unit 210 up to a minute unit in the same manner as described above, so that the line video is reproduced at the line video reproduction speed It can be reproduced along with it.

The train simulator device 200 according to an embodiment of the present invention may be configured to determine the line image reproduction speed using Equation 1 or Equation 2 in the simulator controller 202, 1 and the result of Equation (2) may be combined to determine the reproduction speed of the line image. In this way, the line image reproduction speed can be determined by various methods that can be modified from this.

On the other hand, the simulator control unit 202 can update the line image reproduction speed when it is necessary to update the line image reproduction speed. As an example, the simulator control unit 202 can update the line image reproduction speed when the line image reproduction speed update cycle arrives. Here, the line video reproduction speed update period may be set to a predetermined period (e.g., 1 second) by the user, and the simulator control unit 202, every time the line video reproduction speed update cycle comes, The line image reproduction speed can be newly determined by the image reproduction speed determination method. That is, when the user operates the train of the train simulator, since the line image reproduction speed needs to be periodically updated according to the traveling speed and the train running speed of the current frame, the simulator control unit 202 sets the line image reproduction speed The speed of eternal reproduction of the track can be determined according to the update period.

As another example, the simulator control unit 202 can update the line image reproduction speed when the frame image under image reproduction is changed or the train running speed is changed. That is, the running speed information of the current frame is changed by changing the frame image under image reproduction, or the train running speed of the train simulator is changed according to the operation (for example, acceleration or deceleration) input by the user through the interface unit 205 The train simulator unit 202 can determine and update a new line image reproduction speed according to the line image reproduction speed determination method described above since the line image reproduction speed also needs to be changed accordingly.

When the line video reproduction speed is updated and the line video reproduction speed is updated as described above, the simulator control unit 202 displays the line video reproduction speed and the line video reproduction signal corresponding to the line video data at the updated display speed (203). Meanwhile, the simulator control unit 202 is a component for controlling various components of the train simulator apparatus 200 and processing various data, and may be implemented by a central processing unit such as a CPU processor.

The display unit 203 can display a line image corresponding to the line image data on the screen according to the line image reproduction signal received from the simulator control unit 202. [ The display unit 211 may be formed in the train simulator 200 to provide a screen to a user and may be a CRT monitor, a liquid crystal display (LCD), a light emitting diode (LED) And may be implemented by various types of display devices that can be applied to the train simulator device 200 such as an organic light emitting diode (OLED).

The virtual frame generation unit 204 analyzes the line image data stored in the line image database unit 201 and outputs the difference between the traveling distance between the first frame image and the second frame image or the traveling speed information corresponding to the first frame image , At least one virtual frame image stored between the first frame image and the second frame image may be generated. As an example, the number of at least one virtual frame image stored between the first frame image and the second frame image is determined according to the average train running speed of the line section corresponding to the first frame image and the second frame image .

As described above, the virtual frame images generated by the virtual frame generation unit 204 may be stored in the line image database unit 201 together with at least one existing frame images. The detailed operation of such a virtual frame generating unit will be described in detail with reference to FIG. 5, and a detailed description thereof will be omitted here.

The interface unit 205 can output the train operation input signal received from the user to the simulator control unit 202. The interface unit 205 may be implemented by a variety of train control devices such as a steering wheel similar to a cab of an actual train and may receive commands from a user about train operations and may be variously changed . The interface unit 205 outputs the train operation input signal received from the user to the simulator control unit 202 so that the train simulator device 200 according to the embodiment of the present invention performs various operations according to the user's input .

The wired / wireless communication unit 206 transmits / receives data to / from the control system 250 by wire or wireless, and outputs the manager control signal received from the control system 250 to the simulator control unit 202. The wired / wireless communication unit 206 may be implemented as a communication module supporting at least one of various types of wired / wireless communication methods such as Internet communication using TCP / IP, WiFi (Wireless Fidelity) and Bluetooth, To the extent known to the person skilled in the art.

As an example, the manager control signal may include the operation signal information, and when the simulator control unit 202 receives the manager control signal including the operation signal information through the wired / wireless communication unit 206, (E.g., progress, stop, etc.) corresponding to the operation signal information can be output through the display unit 203. [ Accordingly, the user (training engineer) can advance or stop the train by operating the train simulator according to the operation signal displayed on the display unit 203. [ In this case, the line image data stored in the line image database unit 201 may have a signal portion subjected to chroma key processing for each frame image, so that the operation signal is changed regardless of the signal state at the time of shooting the line image So that driving education can be performed according to the signal.

Meanwhile, the control system 250 may be installed apart from the train simulator device 200 according to an embodiment of the present invention, and may be operated by a controller or automatically operated by the control system 250, The control signal can be transmitted to the wired / wireless communication unit 206 of the train simulator device 200. For example, the manager control signal may include not only the above-described operation signal information but also an input signal for an unexpected situation during the train operation, and an input signal for the unexpected situation may be included in the manager control signal And is transmitted to the train simulator device 200, the simulator control unit 202 outputs an unexpected situation corresponding to the received manager control signal to the display unit to test the user's handling method.

In summary, the train simulator device 200 according to an embodiment of the present invention described above with reference to FIG. 2, when recording a line image as a moving image, not only includes at least one frame image, The line image reproduction speed is finely adjusted according to the result of comparing the traveling speed information and / or the traveling distance information with the train traveling speed of the train simulator using the line image data stored together with the speed information and / or the traveling distance information, It is possible to provide the user with a running image of the train simulator.

[

The image recording unit 301 can be implemented as a general moving image photographing device as a component that can record a line image as shown in FIG. 3 and generate line image data. As an example, the video recording unit 301 may be installed in a driving room of a train that runs a real line section, and records a picture of the same screen as the view angle of the train driver as shown in FIG.

The image data storage database unit 302 may store the line image data generated by the image recording unit 301 and may be implemented as a general data storage device.

The storage format of the line image data shown in FIG. 4 is the same as that for storing the line image data in the line image database unit 201 of the train simulator device 200 according to the embodiment of the present invention described above with reference to FIG. It can be the data field format used.

4, line image data used in the train simulator device 200 according to an embodiment of the present invention may include a frame number (No.), frame image information, a traveling speed, and a traveling distance have.

Here, the frame number may be a consecutive serial number for distinguishing each frame image, and the frame image information is an area where an actual frame image can be stored. The running speed is the running speed of the train at the moment the corresponding frame image is photographed. The running distance is the running distance (distance from the reference point) of the train at the moment of shooting the corresponding frame image, The distance has been described above with reference to FIG. 2 and FIG. 3, and a detailed description thereof will be omitted here.

On the other hand, when the line image data generated by the line image recording apparatus 300 according to the embodiment of the present invention does not include the travel distance information of the train at the moment of recording the line image, A post-processing operation for further storing the distance information can be additionally performed. In other words, if the track image of the line is seen, the location index is installed in units of 100 meters or 200 meters, and the current mileage information (kilobiles) can be inputted and stored for each frame image. Accordingly, the line image data can be stored in association with the traveling speed information of the recorded image and the distance value (traveling distance information) from the starting point for each frame image. The train simulator device 200 according to an embodiment of the present invention can directly move to a specific position or set a start position to be set at an early stage using the travel distance information.

The storage format of the line image data shown in FIG. 4 is an example, and the storage format of the line image data used in the train simulator device 200 according to an embodiment of the present invention is either a traveling speed or a traveling distance It will be understood that the invention may be varied in many ways within the scope and range known to those skilled in the art.

5 is a diagram illustrating an example of a virtual frame generated by a virtual frame generation unit of a train simulator device according to an embodiment of the present invention.

2, the virtual frame generation unit 204 of the train simulator apparatus according to an embodiment of the present invention analyzes the line image data stored in the line image database unit 201, At least one virtual frame image stored between the first frame image and the second frame image may be generated according to the traveling distance difference between the image and the second frame image or the traveling speed information corresponding to the first frame image.

Since the travel distance value per one frame image is large in the line image taken while the train equipped with the line image photographing apparatus 300 is traveling at high speed, the train simulator apparatus 200 can calculate the line image photographed in the high- The intermittent line image may be interrupted while being interrupted.

For example, when a train equipped with the line video image pickup apparatus 300 takes a moving picture at 60 frames per second and travels at 100 km / h in the corresponding section at the time of shooting the line image, 60/60/60), the line image data is recorded. However, if the user operating the train simulator device 200 travels at a low speed such as within 5 km per hour, if the line video reproduction speed is slowed and the line video is reproduced, the frame image becomes absolutely insufficient, A disconnection occurs.

The virtual frame generation unit 204 generates a virtual frame based on the first frame image and the second frame image in order to eliminate the image disconnection due to the limit of the line image data of 60 frames per second when the train of the train simulator device 200 is traveling at low speed. A virtual frame image that is not actually photographed can be generated and stored in the line image database unit 201 by comparing and analyzing the second frame image.

For example, when the line image photographed by the line image photographing apparatus 300 is a standard HD image produced by storing a screen of 60 frames per second, the first frame 510, The second frame 520 and the third frame 530 may be frame images actually photographed at intervals of 1/60 second, respectively, and may include a first virtual frame 511, a second virtual frame 512, The third virtual frame 521 may be the virtual frame images generated by the virtual frame generation unit 204.

On the other hand, the virtual frame generation unit 204 generates a virtual frame based on the running distance information between the first frame image and the second frame image or the running speed information corresponding to the first frame image, And may determine the number of at least one virtual frame image to be stored. 5, two virtual frames 511 and 512 are generated between the first frame 510 and the second frame 520 and two virtual frames 511 and 512 are generated between the second frame 520 and the third frame 530. In other words, A virtual frame 521 may be generated in the first frame 510 and the second frame 520. This is because the traveling speed and the traveling distance difference between the first frame 510 and the second frame 520 are different between the second frame 520 and the third frame 530, It is possible that a larger number of virtual frames are required between the first frame 510 and the second frame 520 because the second frame 520 has a larger value than the difference between the traveling speed and the traveling distance between the first frame 510 and the second frame 520. [ As described above, the virtual frame generation unit 204 generates a larger number of virtual frames as the traveling speed or the traveling distance difference between the first frame image and the second frame image increases, and outputs the virtual frames to the line image database unit 201 Can be stored.

Meanwhile, the number of at least one virtual frame image stored between the first frame image and the second frame image may be determined according to the average train running speed of the line section corresponding to the first frame image and the second frame image have. Here, the average train running speed means an average running speed of trains operating in corresponding real line sections, and the average running speed of the trains is slow in the vicinity of the train station or in many surrounding buildings, The average speed of trains can be accelerated in this possible range.

Therefore, when the average train speed of the corresponding line section is high, the line section is a section in which the trains generally travel at a high speed, and the possibility that the user of the train simulator travels at a low speed in the line section is low. The number of virtual frame images can be set to a small number. On the other hand, when the average train running speed of the line segment is small, it is highly likely that the line segment is a section where the train slows down like the vicinity of the train station, so that the user of the train simulator is likely to run at a low speed in the line segment , It is possible to set a larger number of additional virtual frame images. Through such an algorithm, the virtual frame generation unit 204 can prevent an unnecessarily large number of virtual frame images from being added to the line video data.

In general, since the line image used in the train simulator is continuously photographed while continuing the line at a fixed viewing angle, the screen change between the first frame 510 and the second frame 520 shown in FIG. 5 And is within a predictable range. Therefore, the virtual frame generation unit 204 generates virtual frames 511 and 512 between the first frame 510 and the second frame 520 using the frame image analysis information, the traveling speed information, and the travel distance information can do. A detailed description of the image processing algorithm for creating a virtual frame between the first frame 510 and the second frame 520 is well known to those of ordinary skill in the art, and a detailed description thereof will be omitted.
