This invention uses Unexamined-Japanese-Patent No. 2009-0105290 which is mentioned later. Therefore, the features of the device configuration described below are all those described in the Patent Publication No. 2009-0105290.

However, the present invention is the most important part of the components disclosed in the Patent Publication No. 2009-0105290 improved to maintain a constant horizontal state at all times regardless of the installation surface of the first and second panels and the first and second cushions Constructive features.

Therefore, the device configuration, features and operation relations described below will be cited in the contents of the Patent Publication No. 2009-0105290 as it is, and will be described in detail with respect to the configuration associated with the main features of the present invention at the rear end.

As shown in Figures 1 and 2, the aerial photographing automatic control unit for the editing system of the present invention, the central computer 100, the controller 200, the photographing unit 300, the monitor 400 and the GPS 500 It is configured to include.

The central computer 100 receives a shooting position vector from the GPS 500 and provides a space for storing overall environment settings for shooting and shooting images and shooting information.

Specifically, 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 aerial photography, an image storage path, an auto focusing time of the camera, a release time, a shutter time, active / passive shooting, a tilt value of the camera (X, Y-axis) and its allowable error range, whether or not to start shooting, and the aerial shooting path can be set.

Here, the auto focusing time refers to the time required to automatically match the focus of the photographing object to the photosensitive surface, and the release time refers to the time required to press the shutter button without shaking.

In addition, the shutter time is a time interval of continuous shooting according to the moving speed of the aircraft, and in order to obtain a desired aerial shooting image, about 80% overlapping can be taken continuously. For example, 80% of the first captured image is captured in duplicate of the second captured image. This results in an accurate continuous image. The error range is a comparison between the set value and the actual shooting environment value, and the slight difference can be ignored without correction.

The photographing control command unit 120 receives the environment information set from the environment setting unit 110, makes an environment judgment on photographing, and issues a command for photographing in the system. The set photographing environment may be transmitted to the storage unit 130.

The storage unit 130 receives and stores the set environment setting information from the photographing control command unit 120, and receives the image photographed from the photographing unit 300 to receive the image information received from the GPS 500. It stores the latitude, longitude, altitude, direction, time, speed, and at least one of the corresponding photographing information among the inclination values (X, Y axis) of the camera from the sensing unit to be described later. That is, the photographed image and the corresponding latitude, longitude, altitude, direction, time, speed, and slope may be classified and obtained. Here, the communication in which the central computer 100 receives the photographing information from the GPS 500 may use IEEE1394, which is a direct communication.

The central computer 100 may further include a display unit 140 and may be connected to the storage unit 130 to display the photographed image and the photographing information corresponding to the photographed image received by the storage unit 130.

The controller 200 is connected to the central computer 100 to receive photographing environment information therefrom, and serves to control and command a photographing command to the photographing unit 300. Here, the controller 200 may use RS-232 communication, which is serial communication with the central computer 100.

In detail, the controller 200 includes an information receiving unit 210 and an execution indicating unit 220, which will be described in detail with reference to FIG. 2.

The information receiving unit 210 receives environment information set from the photographing control command unit 120 of the central computer 100, and values of tilts of the camera left, right, left, and front and back sensed by the photographing unit 300 (X, Y). Axis value) can be received and transmitted to the storage 130. The received environment setting information may be transmitted to the execution instruction unit 220.

The performance instructing unit 220 may receive environment setting information from the information receiving unit 210 and may substantially give a camera photographing command to the photographing unit 300.

Referring back to FIG. 1, the photographing unit 300 is connected to the central computer 100 and the controller 200 to control a photographing environment and perform photographing according to a command of the controller 200.

In detail, the photographing unit 300 includes a sensing unit 310, a correction unit 320, a first horizontal control driver 330, a second horizontal control driver 340, a direction angle control driver 350, and a zoom ( Zoom) control unit 360, camera 370, vibration control unit 380 and the 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 detects the inclination values (X, Y axes) of the camera 370 when the image is taken. The detected tilt value is transmitted to the information receiving unit 210 of the controller 200 so that the central computer 100 can store it. The tilt value is also transmitted to the correction unit 320 to correct the tilt value of the camera. Here, the inclination values (X, Y axis) of the camera 370 to the left and right, the X and Y axis of rotation drive axis of the first horizontal control driver 330 is the Y axis of rotation drive axis of the second horizontal control driver 340. When the camera 370 is indicative of the degree of change inclined to the axis. For example, when the direction of travel 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) or X-axis which is left and right direction. Is the slope value of the Y-axis or the X-axis.

Hereinafter, the inclination values of the camera 370 to the left and right and front and rear are referred to as the inclination values (X and Y axes) for convenience of explanation.

The correction unit 320 compares the information received from the sensing unit 310 and the performance instruction unit 220, the inclination value (X, Y axis) of the camera 370 detected by the sensing unit 310 The deviation value may be extracted to keep the camera 370 horizontal by comparing the preset slope values X and Y axes. When the deviation occurs by the comparison to the preset tilt value (X, Y axis) or more than the error range, the first horizontal control driver of the photographing unit 300 to maintain the shooting performance environment having the set tilt value ( 330 and the second horizontal control driver 340.

That is, the first horizontal control driver 330 receives the deviation value of the tilt value of the X-axis of the camera 370 from the corrector 320 and maintains the tilt value of the camera 370 at a preset value. do. That is, when the aircraft is inclined along the X axis (left and right) during aerial photography, the camera is also inclined as much as the inclination, so that the tilted deviation value is received by the correction unit 320 and corrected to a preset value. The control driver 330 is driven.

In addition, the second horizontal control driver 340 receives the deviation value of the inclination value of the Y-axis 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 inclined to the Y axis (back and forth) during aerial photography, the camera is also inclined as much as the inclination, so that the inclination deviation value is received by the correction unit 320 and is corrected to a preset value. The driving unit 340 is driven.

The first horizontal control driver 330 and the second horizontal control driver 340 may be driven simultaneously in correcting the X and Y axis inclination values, and the degree of inclination of the first horizontal control driver 330 to the X axis And control the degree to which the second horizontal control driver 340 is inclined along the Y axis. In this case, even if the tilt value changes in any direction in the front, rear, left, and right directions, the tilt change value may be corrected by the first and second horizontal control drivers 330 and 340.

Accordingly, the camera 370 may acquire an accurate image image by vertical orthogonal imaging while always maintaining horizontality. Here, the first and second horizontal control drivers 330 and 340 may be configured as a DC motor such as an AC motor or a DC stepping motor and a DC servo motor. A control process of the first and second horizontal control drivers 330 and 340 will be described in detail with reference to FIG. 3.

The direction angle control driver 350 may compare the photographing direction value set by the central computer 100 with the aircraft direction value received by the GPS 500 so that the camera maintains the first set direction. In other words, when the shooting route is set to a straight line, if the aircraft deviates from the linear axis, the direction of the camera is controlled in the opposite direction to the deviation direction, so that the shooting direction can be maintained even if the aircraft deviates from the linear axis. Here, the direction angle control driver 350 may be configured as a DC motor such as an AC motor or a DC stepping motor and a DC servo motor. A control process of the direction angle control driver 350 will be described in detail with reference to FIG. 4.

The zoom controller 360 may compare the photographing altitude value set by the central computer 100 with the aircraft altitude value received by the GPS 500 so that the camera 370 maintains the set altitude. have. For example, if you specify the altitude of the area you want to capture, if the aircraft rises or descends from the altitude value, you can control the zoom of the camera lens. will be. That is, when the aircraft proceeds higher than the set altitude, the zoom control unit 360 zooms in, and when the aircraft progresses lower than the set altitude, the altitude of the captured image may be constant by zooming out. A control process of the zoom adjusting unit 360 will be described in detail with reference to FIG. 5.

The camera time controller 390 may compare the photographing speed value set by the central computer 100 with the aircraft speed value received by the GPS 500 so that the camera 370 maintains the set photographing speed. When the degree of redundancy of images to be taken continuously is specified, if the aircraft proceeds beyond the set speed, the shutter speed can be adjusted accordingly to maintain the degree of redundancy of the continuous images by changing the speed of the aircraft.

For example, if you specify 80% redundancy, set the aircraft speed to 100 km / h and set the shutter time to 8 sec. If the aircraft's speed changes and proceeds to 120 km / h, the redundancy is maintained at 80%. In order to do this, the shutter time is controlled to 6 sec faster. In addition, the shutter time may be manually set in consideration of the time for transferring the image captured by the camera to the central computer 100. The camera continuous shooting control process of the camera time controller 390 will be described in detail with reference to FIG. 6.

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 an image data input / output port (eg, IEEE 1394) of the central computer 100. The camera 370 is connected to the zoom control unit 360 and the camera time control unit 390 internally so that the zoom of the camera lens is adjusted so that the shooting altitude is maintained and the overlapping of the captured image can also be kept constant. have. In addition, the camera 370 is externally connected to the first and second horizontal control drivers 330 and 340 so that the X and Y axis inclination values of the camera 370 are adjusted so that vertical orthogonal photography is always maintained. Can be done. In addition, the camera 370 may be externally connected to the direction control driver 350 to perform vertical orthogonal imaging while maintaining a constant shooting direction angle of the camera 370.

The vibration control unit 380 serves to suppress the vibration generated due to the shaking of the aircraft when the camera photographing. The vibration control unit 380 is attached to the inside of the photographing unit 300 and surrounds the up and down dustproof device (not shown) for controlling the up / down direction vibration and the camera 370 to control the external air resistance and left / right direction vibration A shock absorbing dustproof device (not shown) may be configured to suppress vibration of the camera. The up and down vibration isolator may be composed of a shaft consisting of two springs. The shock absorbing dustproof device may be an outer support shaft of the photographing part 300 and may serve to fix the driving parts 330, 340, 350, the upper and lower dustproofing devices, and the camera 370.

The monitor 400 is connected to the camera 370 of the photographing unit 300 and serves to output and provide photographed images and photographing information. The output may be provided in real time.

The GPS 500 determines the position vector of the aircraft by receiving microwaves transmitted from 24 satellites orbiting the mid-orbit. The location vector information may be acquired and transmitted to the storage unit 100 of the central computer 100. The location vector information may be latitude, longitude, altitude, direction, time, speed, and the like.

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

Referring to FIG. 3, the X and Y axis tilt value control processes of the first horizontal control driver 330 and the second horizontal control driver 340 according to the present invention include setting an inclination value A (S30), Receiving the sensing value (B) (S31), determining whether the value of | BAC | is within the error range (S32), extracting and calculating the deviation value (S34), if the deviation is out of the error range, Command (S36) to control the tilt value (X38, Y-axis) by driving the first horizontal control driver 330 and the second horizontal control driver 340 (S38), the process In step S39, a new driving value C is obtained.

Specifically, the method of the present embodiment starts from the step (S30) of setting the inclination value (A) of the imaging unit in the central computer 100, wherein the motor drive value (C) is initially 0, so the value at this time is 0 It is done. After the inclination value is set (S30), the sensing unit 310 of the photographing unit 300 receives the sensing value B, which detects the actual camera tilt at the time of photographing (S31), and determines whether the value is within the error range. The process goes to step S32. For example, checking the error range may be determined as a value of | B-A-C |.

In the determining step (S32), if the error range is within the first horizontal control driver 330 and the second horizontal control driver 340 is photographed without driving, but if the error is exceeded the step of extracting and calculating the deviation value ( Go through S34). In operation S36, a correction command for the deviation value is issued. In response to the correction command S36, the first horizontal control driver 330 and the second horizontal control driver 340 are driven by the deviation value (S38), and the photographing state (α) is set in the environment in which the tilt is controlled. In addition, the driven value becomes a new motor driving value C and is again determined whether it is in an error range (S32).

For example, if the error range is 1 degree and the value of | BAC | is examined, and the set tilt value A and the initial driving value C are 0 degrees, the sensed camera tilt value B is 3 degrees. | BAC | The value is 3. That is, beyond the margin of error. Accordingly, the driving units 330 and 340 are driven to perform a motor driving of 3 degrees. Then, if the camera tilt change of 2 degrees occurs again, the sensing value is always determined based on the set value, so the sensing value (B) is 5 degrees instead of 2 degrees, and the C value is 3 degrees. The value goes through a two-degree judgment procedure.

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

Referring to FIG. 4, the direction control process of the direction angle control driver 350 of the present invention may include setting a direction value A (S10), receiving a GPS value B (S11), | BAC | Determining whether the value is within the error range (S12), extracting and calculating a deviation value (S14) when the error is out of the error range, commanding correction for the deviation value (S16), and driving the direction angle control driver. And controlling the direction (S18), and acquiring a new driving value (C) through the process (S19).

Specifically, the method of the present embodiment starts from the step (S10) of setting the direction value (A) <56> in the central computer 100, wherein the motor drive value (C) is initially 0, so the value at this time is 0. After the direction value is set (S10) and receives a GPS value (B) that detects the actual aircraft direction at the time of shooting from the GPS 500 (S11) and determines whether it is a value within the error range (S12). For example, checking the error range may be determined as a value of | B-A-C |.

In the determination step S12, if the direction angle control driver 350 photographs without driving, but exceeds the error range, the direction angle control driving unit 350 performs the step S14 of extracting and calculating the deviation value. In operation S16, a correction command for the deviation value is issued. By the correction command S16, the direction angle control driver 350 is driven (S18), whereby the direction angle control driving unit 350 enters the photographing standby state β in an environment in which the direction angle is controlled. Then, the driven value becomes a new drive value C, and it is again determined whether it is in an error range (S12).

5 is a flowchart illustrating an altitude control process of a zoom control unit of an aerial shooting automatic control unit for an editing system according to an exemplary embodiment of the present invention.

Referring to FIG. 5, the altitude control process of the zoom control unit 360 of the present invention may include setting an altitude value A (S50), receiving a GPS value B (S51), | Determining whether the value of BAC | is within an error range (S52), extracting and calculating a deviation value if it is outside the error range (S54), commanding correction for the deviation value (S56), and a zoom control unit ( Controlling the zoom of the camera lens by driving 360 (S58); and acquiring a new driving value (C) through the process (S59).

Specifically, the method of the present embodiment starts with the step S50 of setting the altitude value A in the central computer 100. At this time, the driving value C is initially zero, so the value at this time is zero. After the altitude value is set (S50), a GPS value B which detects the actual aircraft altitude at the time of shooting is received from the GPS 500 (S51), and it is determined whether it is a value within an error range (S52). For example, checking the error range may be determined as a value of | B-A-C |.

In the determination step (S52), if the error is within the zoom range 360, the zoom adjusting unit 360 photographs without driving, but if it exceeds the error range, the zoom value is extracted and calculated (S54). In step S56, a correction command for the upper deviation value is issued. In response to the correction command S56, the zoom controller 360 is driven (S58), whereby the zoom adjusting unit 360 enters a shooting standby state Γ in an environment in which the zoom of the camera lens is controlled. Then, the driven value becomes a new drive value C, and it is again determined whether it is in an error range (S52).

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

Referring to FIG. 6, in the camera continuous shooting control process of the camera time controller of the present invention, the step S70 of setting a speed value A and a shutter time value D and a GPS value B are received S71. ), Determining whether the value of ((A * D) / (B * C) |) is within an error range (S72), extracting and calculating a deviation value when it is outside the error range (S74), and In operation S76, the camera time control unit is driven to control the continuous photographing redundancy, and in operation S79, a new driving value C is obtained.

Specifically, the method of the present embodiment starts from the step (S70) of setting the speed value (A) and the shutter time value (D) in the central computer 100, wherein the drive value (C) is initially 0, Is set to 0. After the speed value (A) and the shutter time value (D) are set (S70), a GPS value (B) that detects the actual aircraft speed at the time of shooting is received from the GPS 500 (S71) to determine whether the value is within an error range. To determine the step (S72). For example, checking the error range may be determined 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 takes a picture without driving, but calculates the deviation value (S74) if it exceeds the error range. In operation S76, a correction command for the upper deviation value is issued. The camera time control unit 390 is driven by the correction command S76 and the shutter time is changed so that the photographing is performed in an environment in which 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. In addition, the driven value becomes a new driving value C and is again determined whether it is in an error range (S72).

Here, if the error range is 1 / 1.5 and look at the value of | (A * D) / (B * C) |, the value of (A) * (D) and (B) * (C) should be the same so that there is no error. 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, the Shtter has not yet driven the camera time controller. Since Time (C = D) is 4sec, the error is over 1 / 1.5. Accordingly, the camera time controller is driven to perform a driving value C for changing the shutter time to 2sec (C). Afterwards, if the aircraft's speed changes again to 4m / sec, the aircraft speed value is always determined based on 0, so the GPS value (B) becomes 4m / sec and the previous (C) value becomes 2sec. It goes through the process.

Another embodiment according to the present invention further comprises a laser radiation unit as shown in Figures 7 and 8 so that the embodiments as described above can be fully implemented to approach the vicinity of the aircraft during the shooting, such as bird shooting interceptors It is configured to block itself.

To this end, in the structure in which the camera base 610 is fixed to the lower surface of the fixed base 600 mounted on the aircraft as shown in Figure 7, the camera base 370 for aerial photography is mounted on the camera base 610, Four laser oscillators 630 are installed at intervals of 90 ° in the circumferential direction of the camera base 610 with the camera base 610 therebetween.

The laser oscillator 630 is a means for oscillating a laser beam, a device that emits a beam having a straightness as is well known.

Therefore, since the laser beam oscillated through the laser oscillator 630 has a form of moving linearly with a thickness of a predetermined diameter, it is very difficult and complicated structure to have a structure for preventing the access of an interference element such as a bird when the beam is used as it is. There is no choice but to have.

However, in the present invention, the linear laser beam is polarized to be converted into a circular beam shape, thereby preventing the access of an interference body such as a bird approaching the periphery of the camera 370 from itself, and the prevention radius is also increased.

To this end, the support 640 of the 'b' shape at the edge corresponding to the point where the laser oscillator 630 is installed at the edge of the fixed base 600 extends downward longer than the protrusion height of the camera 370 protrudes do.

A circular polarizer 650 is installed at a portion bent in a 'b' shape, and the circular polarizer 650 is the same as the example of FIG. 8, and the laser beam oscillated from the laser oscillator 630 passes through the center thereof. Configured to do so.

In addition, a reflecting plate 660 is provided at a point at which the laser beam penetrating the circular polarizer 650 reaches. The reflecting plate 660 preferably has a reflecting mirror, and the beam is directed outward in a state inclined at 45 °. It is arranged to reflect the light.

Here, the circular polarizer 650, as shown in Figure 8, includes a cylindrical fixing guide 700, the linear polarizing plate 710 is fixed to the hollow portion of the fixing guide 700.

In addition, a cylindrical rotation guide 720 is rotatably coupled to the lower portion of the fixed guide 700, and the λ / 4 wave plate 730 is fixed to the inner hollow of the rotation guide 720, and the rotation guide The lower portion of the 720 is integrally formed with the power connection portion 740 having an internal hollow.

In addition, the belt 750 is wound around the power connector 740, and the belt 750 is connected to the rotary motor 760 to transmit the power of the rotary motor 760 to the power connector 740. .

In this case, the linear polarizer 710 polarizes the laser beam in the unpolarized state to have a linear shape, and the λ / 4 wave plate 730 converts the linearly polarized beam into a circularly polarized beam.

Here, the concepts of linear polarization and circular polarization are briefly described. When the electric field direction of light is always decomposed into two linearly polarized components perpendicular to each other, one of the two is called a vertical polarization component and the other is a horizontal polarization. If there is no phase difference between the light of the vertical polarization component and the horizontal polarization component among these polarization components, or π, linearly polarized light, that is, linearly polarized light, and other polarized light having an elliptic polarization is elliptical polarization. The case of / 4 is called circularly polarized light.

Accordingly, the λ / 4 wave plate 730 is a means for changing the linear polarization to circular polarization by adjusting the phase difference to π / 4, and the rotation motor 760 is the λ / 4 wave plate 730 to find the phase difference. ) Is a means for rotating, and in some cases it may be controlled to be an elliptical polarization.

In this configuration, since the circularly polarized laser beam is radiated and radiated from at least four locations (90 ° intervals) from the lower side of the camera 370 to the radially outer side of the camera 370 during aerial shooting, Direct access to birds, etc. is blocked directly below the source, thereby enabling accurate and smooth aerial photography without being affected by the interference.
