1 and 2, an aviation photographing automatic control unit for an editing system according to the present invention includes a central computer 100, a controller 200, a photographing unit 300, a monitor 400, and a GPS 500 .

The central computer 100 receives the photographing position vector from the GPS 500 and provides a space for storing the overall environment setting for the photographing and the photographing image and photographing information.

The central computer 100 includes an environment setting unit 110, a shooting control command unit 120, a storage unit 130, and a display unit 140, which will be described in detail with reference to FIG. 2 .

The environment setting unit 110 may set a desired shooting environment for shooting an aerial image. The environment setting unit 110 may set a desired shooting environment such as an image storage path, a camera's Auto Focusing Time, a Release Time, a Shutter Time, Y axis), the tolerance range thereof, the start of shooting, and the aerial photographing route.

Here, the Auto Focusing Time refers to the time required to automatically align the focus of the object to be photographed to the photosensitive surface, and the Release Time refers to the time required to press the shutter button without shaking.

And Shutter Time refers to the time interval of continuous shooting according to the moving speed of the aircraft. In order to obtain the desired aerial image, about 80% of the time can be continuously shot. For example, 80% of the first shot will be shot with the second shot overlapping. This allows the final, accurate, continuous image to be obtained. And the error range is the limit of the negligible level by comparing the set value with the actual shooting environment value so that the slight difference can be ignored without correction.

The photographing control command unit 120 receives environment information set by the environment setting unit 110 and makes an environment judgment for photographing, and issues a command for shooting in the system. And may transmit the set shooting environment to the storage unit 130.

The storage unit 130 receives and stores the set environment setting information from the image capturing control command unit 120 and receives the captured image from the image capturing unit 300, (X, Y axis) of the camera from the left and right front and rear of the camera to be described later along with the photographing information corresponding to at least any one of the photographing information, the latitude, the longitude, the altitude, the direction, the time and the speed. In other words, the captured image can be obtained by classifying values such as latitude, longitude, altitude, direction, time, speed, and slope. Here, the communication through which the central computer 100 receives the photographing information from the GPS 500 can use the direct communication IEEE1394.

The central computer 100 may further include a display unit 140 and may be connected to the storage unit 130 to display shot images and shooting information corresponding to the shot images received by the storage unit 130. [

The controller 200 is connected to the central computer 100, receives the photographing environment information from the central computer 100, and instructs the photographing unit 300 to actually command photographing. The controller 200 may use RS-232 communication, which is a serial communication with the central computer 100.

Specifically, the controller 200 includes an information receiving unit 210 and an execution instruction unit 220, which will be described in detail with reference to FIG.

The information receiving unit 210 receives the environment information set from the image capturing control command unit 120 of the central computer 100 and stores the values of the inclination of the camera in the left and right direction of the camera sensed from the photographing unit 300 Axis value) to the storage unit 130. FIG. And can transmit the received configuration information to the performance instruction unit 220. [

The performance instruction unit 220 may receive environment setting information from the information receiving unit 210 and may actually issue a camera shooting instruction to the photographing unit 300.

Referring to FIG. 1 again, the photographing unit 300 is connected to the central computer 100 and the controller 200 to control the photographing environment and perform photographing in response to a command from the controller 200.

The image sensing unit 300 includes a sensing unit 310, a corrector 320, a first horizontal control driver 330, a second horizontal control driver 340, a direction angle control driver 350, Zoom control unit 360, a camera 370, a vibration control unit 380, and a camera time control unit 390, which will be described in detail with reference to FIG.

The sensing unit 310 is attached to the outside of the camera 370 and senses tilt values (X, Y axes) of the camera 370 at the time of photographing. The detected tilt value is transmitted to the information receiving unit 210 of the controller 200 so that the central computer 100 can store the tilt value and also transmits the tilt value to the correcting unit 320 to correct the tilt value of the camera. Here, the inclination value (X, Y axis) of the camera 370 in the left and right direction is the X axis of the first horizontal control driver 330 and the Y axis of the second horizontal control driver 340 The degree of change of the camera 370 with respect to the axis. For example, when the direction of the aircraft is Y-axis and the direction perpendicular to the Y-axis is X-axis, when the aircraft is inclined to the Y-axis (i.e., front and rear) Is the y-axis or x-axis slope value.

Hereinafter, the tilt values of the camera 370 in the left and right forward and backward directions are referred to as tilt values (X, Y axis) for convenience of explanation.

The correction unit 320 compares the information received from the sensing unit 310 and the performance instruction unit 220 and compares the tilt value (X, Y axis) of the camera 370 sensed by the sensing unit 310, And a predetermined slope value (X, Y axis), so that the deviation value can be extracted so that the camera 370 is kept horizontal. When the difference is greater than or equal to the predetermined slope value (X, Y axis) by the comparison, the first horizontal control driver (not shown) of the photographing unit 300 330 and the second horizontal control driver 340. [0033]

That is, the first horizontal control driver 330 receives the deviation value of the X-axis inclination value of the camera 370 from the corrector 320 and maintains the inclination value of the camera 370 at a preset value do. That is, when the aircraft is tilted (horizontally) on the X axis during the aerial photographing, since the camera is also tilted by the tilted angle, the correction unit 320 receives the tilted deviation value, The control driver 330 is driven.

The second horizontal control driver 340 receives the deviation value of the Y-axis inclination value of the camera 370 from the correction unit 320 and maintains the inclination value of the camera 370 at a predetermined value do. That is, when the aircraft is tilted in the Y-axis (forward and backward) during the aerial photographing, since the camera also tilts with the inclination, the correction unit 320 receives the tilted deviation value, The driving unit 340 is driven.

The first horizontal control driver 330 and the second horizontal control driver 340 can be simultaneously driven in correcting the X and Y axis tilt values. The first horizontal control driver 330 and the second horizontal control driver 340 can adjust the tilt of the first horizontal control driver 330 And to control the degree to which the second horizontal control driver 340 is tilted in the Y axis. In this case, the first and second horizontal control drivers 330 and 340 can correct the tilt change value even if the tilt value of the aircraft changes in the forward, backward, left or right direction.

Therefore, the camera 370 can always acquire an accurate image image by vertical orthophoto while maintaining the horizontal position. Here, the first and second horizontal control drivers 330 and 340 may be constituted by an AC motor, or a DC motor such as a DC stepping motor and a DC servo motor. The control process of the first and second horizontal control drivers 330 and 340 will be described in detail with reference to FIG.

The direction angle control driver 350 may compare the photographing direction value set by the central computer 100 with the direction value of the airplane received by the GPS 500 so that the camera maintains the initial direction. In other words, if the photographing route is defined as a straight line, if the aircraft departs from the linear axis, the direction of the camera can be controlled by controlling the direction of the camera in the opposite direction. Here, the direction angle control driver 350 may be constituted by an AC motor or a DC motor such as a DC stepping motor and a DC servo motor. The control process of the direction angle control driver 350 will be described in detail with reference to FIG.

The zoom adjustment unit 360 may compare the shooting altitude value set by the central computer 100 with the altitude value of the aircraft received by the GPS 500 to maintain the altitude of the camera 370 have. For example, if the altitude of the area to be photographed is specified and the aircraft is elevated or lowered from the altitude value, the zoom level of the camera lens can be controlled in the opposite direction. will be. That is, if the aircraft travels at a height higher than the set altitude, the zoom control unit 360 zooms in. If the aircraft travels lower than the set altitude, the altitude of the photographed image can be made constant by zooming out. The control process of the zoom controller 360 will be described in detail with reference to FIG.

The camera time controller 390 may compare the photographing speed value set in the central computer 100 with the airplane speed value received from the GPS 500 to maintain the photographing speed set by the camera 370. [ When the degree of redundancy of an image to be continuously shot is specified, if the aircraft deviates from the set speed, the shutter speed can be adjusted accordingly and the redundancy of the continuous shooting image can be maintained even by the speed change of the aircraft.

For example, if you specify 80% of the redundancy, set the aircraft speed to 100 km / h, and set the Shutter Time to 8 sec., If the speed of the aircraft changes to 120 km / h, Shutter Time is controlled to 6 sec faster. In addition, it is also possible to manually set the shutter time in consideration of the time taken for the image photographed by the camera to be transmitted to the central computer 100. [ The camera continuous shooting control process of the camera time control unit 390 will be described in detail with reference to FIG.

The camera 370 performs image capturing and transmits the photographed image to the storage unit 130 of the central computer 100. [ The image transmission path may use a video data input / output port (e.g., IEEE 1394) of the central computer 100. The camera 370 is internally connected to the zoom controller 360 and the camera time controller 390 to adjust the zoom of the camera lens to maintain the shooting height and to maintain the overlapping have. The camera 370 is externally connected to the first and second horizontal control drivers 330 and 340 so that the tilt values of the X and Y axes of the camera 370 are adjusted, Can be performed. Further, the camera 370 may be externally connected to the directional angle control driver 350 to perform orthorectification while maintaining a photographing direction angle of the camera 370 constant.

The vibration control unit 380 suppresses the vibration generated due to the shaking of the airplane during the camera shooting. The vibration control unit 380 surrounds the up / down vibration preventing device (not shown) and the camera 370 attached to the inside of the photographing unit 300 to control the up / down vibration and controls the external air resistance and the left / And a shock absorbing / vibration preventing device (not shown) so as to suppress the vibration of the camera. The up-and-down vibration device may be constituted by a shaft constituted by two springs. The shock absorbing / damping device may be an outer supporting shaft of the photographing unit 300 and may be used to fix the driving units 330, 340, 350, the vertical vibration preventing device, and the camera 370.

The monitor 400 is connected to the camera 370 of the photographing unit 300 and outputs a photographing image and photographing information. The output may be provided in real time.

The GPS 500 receives the microwave emitted from twenty-four artificial satellites orbiting the orbit, and determines the position vector of the aircraft. And acquire the position vector information and transmit the information to the storage unit 100 of the central computer 100. [ The position vector information may be latitude, longitude, altitude, direction, time, speed, and the like.

3 is a flowchart illustrating a process of controlling the X-axis and Y-axis inclination values of the first horizontal control driver and the second horizontal control driver of the aviation photographing automatic control unit for an editing system according to the embodiment of the present invention.

3, the process of controlling the X-axis and Y-axis inclination values of the first horizontal control driver 330 and the second horizontal control driver 340 includes steps S30 and S30 of setting a slope value A, (S32) of determining whether the value of | BAC | is within an error range, extracting a deviation value if the error value is outside the range (S34), calculating a difference value (X, Y axis) by driving the first horizontal control driver 330 and the second horizontal control driver 340 in step S38. In step S38, (Step S39) of acquiring a new drive value C through the step S40.

More specifically, the method of the present embodiment starts from the step S30 of setting the slope value A of the photographing section to the central computer 100, and the motor drive value C is initially 0, . After the tilt value is set (S30), the sensing value (B) that senses the actual camera tilt at the time of photographing is received from the sensing unit 310 of the photographing unit 300 (S31) and it is determined whether it is within the error range Step S32 is performed. As an example, it is possible to determine the value within the error range as the value of | B-A-C |.

If the first horizontal control driver 330 and the second horizontal control driver 340 shoot but do not operate if the error is within the error range in the determination step S32, S34). And a step S36 of issuing a correction command for the deviation value. The first horizontal control driver 330 and the second horizontal control driver 340 are driven by the deviation value by the correction instruction S36 in step S38 and the image sensing standby state? Then, the driven value becomes a new motor drive value C and it is again judged whether or not it is in the error range (S32).

For example, if the error range is 1 degree and the value of | BAC | is examined, if the actually tilted camera value A is 3 degrees when the set tilt value A and the initial driving value C are 0 degrees | BAC | The value is 3. That is, it exceeds the error range. The driving units 330 and 340 are driven to perform three-degree motor driving. If the camera tilt is changed again by 2 degrees, the sensing value is always based on the set value. Therefore, the sensing value B is 5 degrees, not 2 degrees, and the C value is 3 degrees. The value is judged to be 2 degrees.

4 is a flowchart illustrating a direction control process of a direction angle control driver of an aviation photographing automatic control unit for an editing system according to an embodiment of the present invention.

Referring to FIG. 4, the direction control process of the direction angle control driver 350 of the present invention includes a step S10 of setting a direction value A, a step S11 of receiving a GPS value B, A step S14 of extracting a deviation value when the value is outside the error range, a step S16 of instructing correction of the deviation value, a step S16 of driving the direction angle control driver, (S18), and acquiring a new driving value (C) through the process (S19).

More specifically, the method of the present embodiment starts from the step S10 of setting the direction value A to the central computer 100, and the motor drive value C is initially 0 at this time, 0. After the direction value is set (S10), a GPS value (B) that senses the actual aircraft direction at the time of photographing is received from the GPS (500) (S11) and it is determined whether it is within the error range (S12). As an example, it is possible to determine the value within the error range as the value of | B-A-C |.

If the directional angle control driver 350 does not drive while the error is within the error range in the determination step S12, and if the error range is exceeded, a step S14 of extracting the deviation value is performed. And a step S16 of issuing a correction command for the deviation value. The directional angle control driver 350 is driven by the correction instruction S16 (S18), and the photographing standby state beta is set in the environment where the directional angle is controlled. Then, the driven value becomes a new driving value C and it is judged again whether or not it is in the error range (S12).

FIG. 5 is a flowchart illustrating an altitude control process of a zoom control unit of an aviation photographing automatic control unit for an editing system according to an embodiment of the present invention.

5, an elevation control process of the zoom adjusting unit 360 of the present invention includes a step S50 of setting an altitude value A, a step S51 of receiving a GPS value B, (S56); determining whether the value of the deviation value is within an error range (S52); calculating a deviation value (S54) when the error value is outside the error range; instructing correction of the deviation value 360) to control the zoom of the camera lens (S58), and acquiring a new drive value (C) through the process (S59).

Specifically, the method of the present embodiment starts from the step S50 of setting the altitude value A in the central computer 100, wherein the drive value C is initially 0, and the value at this time is zero. After the altitude value is set (S50), the GPS value (B) that senses the actual aircraft altitude at the time of photographing from the GPS (500) is received (S51) and it is determined whether it is within the error range (S52). As an example, it is possible to determine the value within the error range as the value of | B-A-C |.

If the zoom range is within the error range in the determining step S52, the zoom adjusting unit 360 shoots the image without driving, and if it exceeds the error range, the deviation value is extracted (S54). And a step (S56) of issuing a correction command for the set value deviation value. The zoom adjusting unit 360 is driven by the correction command S56 (S58), and the photographing standby state (?) Is set in an environment in which the zoom of the camera lens is controlled. Then, the driven value becomes a new driving value C and it is again determined whether it is in the error range (S52).

6 is a flowchart illustrating a camera continuous shooting control process of the camera time control unit of the automatic photographing control unit for an editing system for an editing system according to an embodiment of the present invention.

6, the camera continuous shooting control process of the camera time control unit of the present invention includes a step S70 of setting a speed value A and a shutter time D, a step S71 of receiving a GPS value B, ), (A * D) / (B * C) | is within an error range (S72); if the value is outside an error range, extracting a deviation value (S74) (S76), a step of controlling the continuous shooting overlapping degree by driving the camera time control unit (S78), and a step (S79) of acquiring a new drive value C through the above process.

Specifically, the method of the present embodiment starts from the step S70 of setting the speed value A and the shutter time value D to the central computer 100, wherein the driving value C is initially 0, The value of 0 is assumed to be 0. After the speed value A and the shutter time value D are set (S70), the GPS value B that senses the actual aircraft speed at the time of photographing is received from the GPS 500 (S71) (Step S72). As an example, it is possible to determine the value within the error range as a value of | (A * D) / (B * C) |.

If it is within the error range in the determination step S72, the camera time controller 390 does not drive the camera, but if it exceeds the error range, the deviation value is calculated (S74). And a step S76 for issuing a correction command for the set value deviation value. The camera time control unit 390 is driven by the correction command S76 (S78), and shooting is performed in an environment in which the shutter time is changed and the redundancy is controlled. At this time, the slope value, the direction angle, and the zoom adjustment value, which were previously controlled in FIGS. 3 to 5, are all controlled at the time of shooting so that the shooting is finally performed. Then, the driven value becomes a new driving value C and it is again judged whether or not it is in the error range (S72).

If the error range is 1 / 1.5 and the value of (A * D) / (B * C) | is examined, the value of (A) * (D) If the speed value B of the actual aircraft received from the GPS 500 is 20 m / sec when the set speed value A is 10 m / sec and the set Shtter Time D is 4 sec, Since the time (C = D) is 4 sec, the error exceeds 1 / 1.5. The camera time control unit is driven to perform the drive value C for changing the Shtter Time to 2 sec (C). If the speed of the aircraft is changed again to 4 m / sec, the aircraft speed is always 0, so the GPS value (B) is 4 m / sec. The process goes through.

The support bearing 620 is most preferably bolted onto the fixed base 600.

In addition, a ring-shaped illumination radiation unit 700 is rotatably assembled to the outside of the support bearing 620.

In this case, the illumination radiation unit 700 includes a ring-shaped rotating body 710 and a plurality of reflecting plates 720 fixed at regular intervals along the outer circumferential surface of the rotating body 710.

In this case, the rotating body 710 is formed of a transparent material to be configured to transmit light, the reflecting plate 720 is installed to be inclined at a predetermined angle with respect to the surface of the rotating body 710.

That is, the reflecting plate 720 is preferably installed inclined at a predetermined angle in the radial direction of the rotating body 710, preferably 45-50 ° inclination angle (R), which is to be described later by the illumination lamp 800 This is to make the irradiated light easy to be reflected and refracted.

In addition, a plurality of dimples 730 are formed on both side surfaces of the reflecting plate 720.

The dimple 730 is formed in the shape of a small circular groove to induce diffuse reflection when light is irradiated.

On the other hand, the outer peripheral surface of the camera base 610 is provided with a plurality of lighting lamps 800 at regular intervals along the radial direction.

The lighting lamp 800 is a lamp configured to blink repeatedly at a predetermined time interval, and the light emitted by the flashing of the lighting lamp 800 is transmitted through the rotating body 710 to be irradiated to the reflecting plate 720 It is composed.

The present invention having such a configuration has the following operational relationship.

Since the plurality of reflecting plates 720 attached to the outer circumferential surface of the rotating body 710 are substantially triangular in shape and protrude outwardly, they cause an interference phenomenon by contact with the outside air while the aircraft is flying, thereby causing itself to rotate. do.

That is, the rotating body 710 is self-rotating during the flight even without a separate driving source due to the presence of the reflecting plate 720.

In particular, since the reflecting plate 720 is inclined, the rotation torque caused by interference with air is further increased to induce smooth rotation.

In addition, the illumination lamp 800 which is periodically flickering during flight emits light, and the emitted light penetrates the rotating body 710 to hit the reflector plate 720 and is then diffusely reflected while the camera 370 is interposed radially. As the light is sown, it warns birds approaching the surroundings, thus blocking the access of birds.

As such, the illumination radiating unit 700 according to the present invention blocks the access of birds by warning the birds approaching the surroundings through self-luminous and diffuse reflection to enable more smooth and accurate aerial photography.
