Description

Real time update system reflecting the topography change by disaster}

The present invention relates to a real-time update system of a digital map reflecting terrain changes caused by disasters and pollution.

Digital map making technology has been steadily evolving to meet the user's desire to use more accurate and photorealistic maps, and is still rapidly developing with the development of aerial photography and image editing technology.

One of the most important parts of the digital map production is to accurately input and synthesize the numerical information, which is the coordinate information, on the map image accurately. For this purpose, it is ideal to ensure that the reference point target installed at the correct position in the aerial photographing process is accurately captured in the aerial photographing image. When the target is photographed in the aerial photographing image, the coordinate image is determined based on the target image in the numerical mapping process. The numeric information must be entered. That is, since accurate numerical information can be input without going through a separate field survey, it is possible to minimize unnecessary waste of time and money in the digital map production process and to significantly increase the reliability of the digital map.

In addition, aerial photography can be used to check terrain changes and errors in numerical information, so that errors in existing digital maps can be updated quickly. Can be done frequently.

Recognizing these advantages, conventionally, various systems have been proposed, including devices that can be targeted for aerial photography at the corresponding positions of ground reference points, and similar technologies such as patents 0919870 and 1009359 have been known.

However, these prior arts have limitations in that the devices must always be locked in place. Of course, since the location should be a location that is well photographed on the camera mounted on the aircraft, it is natural that the location should be exposed to the outside, which means that it is exposed to the weather as it is. Therefore, the corrosion and damage of the device is inevitable, it is obvious that the failure will be frequent, there was a limit to the effectiveness of the technology.

In order to solve this problem, the device may be installed at the corresponding position of the reference point only in the case of aerial photography. However, it is not easy to accurately install a large number of devices at each reference point position in a relatively large area, and there is a problem that time and cost are consumed because it requires expertise in installation work.

As a result, due to the above-mentioned realistic limitations, there has been a demand for a solution to solve the irrationality of giving up the precision of the digital map obtained by accurately displaying the reference point in the aerial photographing image.

On the other hand, if a change occurs in an artificial structure such as a natural topography or a building due to a sudden disaster or pollution, the user needs to detect it and reflect it in updating the digital map. Due to the difficulty in recognizing, the changed terrain due to disaster or pollution could not be reflected in the updating of digital maps.

Accordingly, the present invention has been invented to solve the above problems, it is possible to precisely match the aerial photographing images and numerical information collected for the production of digital maps by the disaster and pollution caused by the increased reliability of the digital map It is a technical task to provide a real-time update system of a digital map that reflects terrain changes.

In addition, the technical problem is to provide a real-time update system of the digital map reflecting the topographical change due to disasters and pollution that allows the user to easily recognize the topographical changes due to the disaster and reflect in the update of the digital map without omission.

The above-described features and effects of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, and thus, those skilled in the art to which the present invention pertains may easily implement the technical idea of the present invention. Could be. As the inventive concept allows for various changes and numerous embodiments, particular embodiments will be illustrated in the drawings and described in detail in the text. However, this is not intended to limit the present invention to the specific disclosure, it should be understood to include all modifications, equivalents, and substitutes included in the spirit and scope of the present invention. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a view schematically showing an installation of a reference point display device according to the present invention, Figure 2 is a block diagram showing an update system according to the present invention, it will be described with reference to this.

The update system according to the present invention includes a ground image collecting device 100 installed in the aircraft 10 and a plurality of reference point display devices 200, 200 ′, 200 ″ installed at one point corresponding to a ground reference point. 200 ') and a numerical map preparation device 300 for editing the aerial photographing image provided from the ground image collecting device 100 and inputting numerical information to complete the numerical map.

The ground image collecting device 100 receives a signal from at least three satellites and checks the current position of the GPS receiver 110, a signal generator 120 transmitting an identification signal of a certain unique frequency band, and the ground in real time. It consists of a high-resolution camera 130 to shoot.

GPS receiver 110 is a known, public device that allows the camera 130 to record the ground position being photographed while checking the current position of the aircraft 10 equipped with the ground image collecting device 100, If it is intended to receive GPS (Global Positioning System) information of the current position while communicating with the satellite, various modifications can be made without departing from the scope of the following claims.

For reference, since the technology for tracking the current GPS position while communicating with satellites is a well-known and tolerant technology, a detailed description of the hardware and software of the GPS receiver 110 according to the present invention will be omitted.

The signal generator 120 transmits an identification signal of a certain unique frequency band so that the reference point display device 200 can recognize the approach of the aircraft 10 equipped with the ground image collecting device 100 and operate the laser 210. It is.

As shown in FIG. 1, the reference point display device 200 is distributed in a relatively large area while being installed in one or more ground structures 20. However, the laser beam irradiated from the reference point display device 200 is sufficient when the aircraft 10 is irradiated when passing through the reference point display device 200, when the aircraft 10 passes or the aircraft is not in close proximity. There is no need to waste power unnecessarily while irradiating the yen laser light. That is, the signal generator 120 transmits the identification signal to determine whether the reference point display device 200 is close to the aircraft 10, so that it can determine whether to irradiate the laser light.

For reference, since the signal generator 120 transmits the identification signal in a state in which it is installed in the moving aircraft 10 even if the identification signal of a predetermined frequency band is transmitted, the reference point display device 200 is a distance from the aircraft 10. Accordingly, the identification signals of various frequencies due to the Doppler effect are received. However, since the altitude, speed, and route of the aircraft 10 are determined, and the frequency band of the identification signal is also determined during aerial photography, the experiment confirms the reception state of the identification signal at the corresponding altitude, speed, and route, and the rate of change and When the section is determined and the determined specific section is designated as 'adjacent' or 'pass through' of the aircraft 10, the reference point display device 200 may estimate the position of the aircraft 10 when the identification signal of the section is received. Can be.

The camera 130 is a high resolution digital camera and may capture a video or a still image in real time. Since the camera 130 is a well-known and common technique, a detailed description of the device will be omitted.

The reference point display device 200 includes a laser 210 for irradiating a laser light upward, a signal detector 220 for receiving an identification signal transmitted by the signal generator 120, and a charger for receiving and charging power supplied thereto ( 230, and a driver 240 for adjusting the length of the anchor bar 280 (see FIG. 3). As described above, the reference point display device 200 is installed at a specific point on the ground, and irradiates a laser beam toward the ground image collecting device 100 of the aircraft 10. In this case, when a change occurs at the specific point due to a disaster or the like, the reference point display device 200 moves along the change, and eventually irradiates the laser light at the moved position. Therefore, the ground image collected by the ground image collecting device 100 is different from the ground image collected previously, and through this, the user can easily recognize the change of the corresponding area and reflect it in the digital map production.

The laser 210 is to irradiate the laser light taken by the camera 130 mounted on the aircraft 10, the laser light has an intensity that does not damage the aircraft 10 aircraft, its identification in the aerial image It is output with easy strength.

The laser 210 is a well-known and public device, and since adjustment of the laser light is a well-known technique, a detailed description of the laser 210 is omitted.

The signal detector 220 measures the frequency by detecting an identification signal among various external signals, and controls the operation of the laser 210 when it is confirmed that the identification signal is a signal of a specified section. As described above, the section is determined according to the change rate by checking the reception state of the identification signal, and when the section is determined, it is designated as 'adjacent' or 'pass through' to be used as a reference for controlling the operation of the laser 210. . In the embodiment according to the present invention, the antenna 221 is formed to increase the reception efficiency of the identification signal, and the antenna 221 is disposed in the case 270 (see FIG. 3).

The charger 230 charges a battery (not shown) by receiving external power. The charger 230 starts charging when connected to external power and ends charging when the power is disconnected.

The driver 240 adjusts the length of the anchor bar 280 while driving by receiving a DC voltage from an external power source and a battery. As the driver 240 forms a public DC motor structure, the driver 240 adjusts the rotation direction according to the polarity direction of the DC voltage. Do it differently. For reference, the driver 240 further includes a switch 241 (see FIG. 6) in an energization circuit with the battery. The driver 240 is wired to operate automatically when electricity is supplied from the DC power source B (see FIG. 4). When the switch 241 is operated, the driver 240 is operated by receiving electricity of the battery charged by the charger 230. The DC voltage is supplied in a direction opposite to the polarity of the DC power source B so that the rotation direction is also reversed. More specifically, as shown in FIG. 9 (wiring diagram schematically showing the wiring state of the driver according to the present invention), the rotating shaft 271 in which the positive polarity of the DC power source B is expressed; The charger 230 and the driver 240 are wired so as to receive DC voltages for operation from the conductor 271a of FIG. 6. The charger 230 receives the DC electricity of the DC power source B to charge the battery, and the driver 240 receives the DC electricity of the DC power B to rotate in one direction.

Subsequently, when the installer operates the switch 241, the DC electric current of the battery supplies the DC voltage to the driver 240. Since the DC electric current of the battery is opposite to the DC voltage polarity of the DC power source B as illustrated, The driver 240 rotates in the other direction.

For reference, since the battery of the charger 230 is used only for the operation of the driver 240, its capacity is small. Therefore, in order to minimize battery consumption, the switch 241 may be preferably configured to maintain a closed state only when pressurized.

In addition, the reference point display device 200 further includes a support 250 (see FIG. 3), a rotation frame 260, a case 270, and an anchor bar 280, which will be described in more detail below.

The digital map preparation device 300 includes an image input unit 310 for receiving an aerial photographing image of the ground image collecting device 100, a drawing unit 320 for creating a drawing image based on the aerial photographing image, and completed. And a numerical information input unit 330 for inputting numerical information into the drawing image, and input / output means 340 for checking the aerial photographing image, the drawing image, etc. while the drawing operator operates for the drawing operation.

The image input unit 310 is for inputting the aerial photographing image in the form of an image file into the digital map preparation device 300, and may be a reader of a conventional storage medium such as a USB drive, a CD drive, a DVD drive, or the like. It may be a communication device that can communicate by connecting a USB cable.

Although omitted in the embodiment according to the present invention, the numerical map preparation device 300 naturally includes storage means (not shown) for storing the aerial photographing image and the drawing image. Therefore, the image input unit 310 may be modified in various ways within the scope of the following claims if the technology applied to store the aerial photographs in the storage means.

The drawing unit 320 connects a plurality of aerial photographing images to produce a single piece, and draws the drawing image that is the background of the numerical map based on the completed aerial photographing image. The final drawing image is completed by manipulating the aerial photographing image and the drawing image outputted by the manipulation. Here, in the present invention, the laser light image included in the aerial photographing image is displayed as a reference point on the drawing image, so that the operator can accurately match the standard when inputting numerical information.

The numerical information input unit 330 inputs numerical information into a drawing image completed through the drawing unit 320 so as to be completed as a numerical map. The numerical information is input based on a reference point of the drawing image. Here, the reference point is the position of the laser light image is a reference point, when drawing through the immersion machine 320, the reference point is displayed on the point where the laser light is photographed, and the coordinates of the reference point are identified and the drawing is applied as the numerical information. Enter in the image. Of course, when the numerical information is input to the drawing image, the entire GPS coordinates are synthesized on the drawing image, and thus, a complete numerical map is finally completed.

The technology of the drawing machine 320 which completes the drawing image based on the aerial photographing image and the technique of inputting numerical information to the reference point of the drawing image and synthesizing the GPS coordinates to the drawing image are known in the digital map production technology field. Since the technology is a common technology, detailed descriptions of hardware and software of the fuser 320 and the numerical information input unit 330 will be omitted.

Figure 3 is a perspective view showing a reference point display device according to the present invention, Figure 4 is an exploded perspective view showing a connection structure of the support and the rotating frame according to the present invention, will be described with reference to this.

The reference point display device 200 according to the present invention, together with the laser 210, the signal detector 220, the charger 230 and the driver 240 described above, the support 250, the rotation frame 260, the case 270 ), The anchor bar 280 and the light emitter 290 is further included.

The support 250 allows the case 270 to which the laser 210 is fixed to aim the laser 210 upwards at all times, so that the laser light of the laser 210 can be accurately irradiated onto the aircraft 10.

The anchor bar 280 is fixed to the case 270 to be pulled out downward, the support 250 is manufactured to a sufficient height so that the withdrawal of the anchor bar 280 is not interfered. In addition, the case 270 is rotatably fixed at the upper end of the support 250, the shape of the drawn anchor bar 280 is to be considered so as not to interfere. For reference, the support 250 is preferably formed in a triangular shape in order to ensure the stability of the case 270 located on the top of the support 250 and the structural stability of the support 250 itself, but is not limited thereto, anchor bar If the structure that can be stably fixed to the rotatable case 270, without interference, provided with 280 may be variously modified within the scope of the following rights.

Subsequently, the support 250 further includes a stopper 254 and a light receiving panel 255.

The stopper 254 is forcing the case 270 which is continuously rotated by the rotation frame 260 or the like to not move when it is held in position, and a pair of the stoppers 254 are disposed to face each other with respect to the case 270.

Referring to FIGS. 10 (an exploded perspective view of a stopper according to the present invention) and FIG. 11 (a diagram schematically showing an operation of the stopper), the stopper 254 may include a housing 254a, A pair of cylinders 254b, a piston 254c fitted to the cylinder 254b, a foot 254d fixed to the end of the piston 254c, and a tank into which gas is introduced to raise the air pressure of the cylinder 254b. 254e, a pump 254f for adjusting the internal pressure of the cylinder 254b while connecting the cylinder 254b and the tank 254e, and a controller for controlling the pump 254f to force outflow of the gas into the cylinder 254b. And 254g.

More specifically, as illustrated in FIG. 11A, the controller 254g controls the pump 254f to inhale the gas in the cylinder 254b to pull the piston 254c. The foot 254d does not contact the case 270. However, when there is a fixed request signal for the current position of the case 270, the controller 254g controls the pump 254f to forcibly move the gas in the tank 254e to the cylinder 254b, so that FIG. As shown in the figure, the foot 254d is brought into close contact with the case 270 through the forward movement of the piston 254c. As a result, since the case 270 is firmly fixed by the pair of stoppers 254 disposed to face each other, the case 270 can be irradiated upward while keeping the current posture stable without rotation.

On the other hand, the light receiving panel 255 is composed of a plurality of light receiving sensors, and is disposed directly below the weight 281 so as to face the weight 281. The light receiving panel 255 receives the reference laser light of the light emitter 290 imparted to the weight 281, and transmits the request signal to the controller 254g when the same light receiving sensor continues to receive the reference laser light for a predetermined time. The stopper 254 is operated.

Rotating frame 260 is to rotatably fix the case 270 to the support 250, and forms a ring shape that can be inserted through the case 270. In the exemplary embodiment according to the present invention, the rectangular frame is formed, but the rotation frame 260 is not limited thereto.

The rotating frame 260 includes a ring-shaped main body 261, a pair of rotation shafts 262 protruding from each other at opposite ends of the main body 261, and a rotation body 262 at right angles to the main body ( It consists of a pair of mounting stage 263 arrange | positioned at the both ends of 261, and a pair of bearing 264 fixed to the mounting stage 263, respectively.

The main body 261 forms a tubular shape in which an electric wire can be built, and forms a ring shape as described above. Here, the two wires are wired so that the pair of rotating shaft 262 and the bearing 264 are separated from each other. That is, the rotating shaft 262 and the bearing 264 is connected to one wire to form a set of two sets to configure the rotating frame 260.

Rotating shaft 262 is disposed so that the pair of the projecting opposite to each other at each end of the main body 261, respectively, is rotatably fixed to the support (250). To this end, a rotation groove 251 in which the rotation shaft 262 is rotatably inserted is formed at a corresponding position of the support 250. Of course, since the pivoting groove 251 is formed to correspond to the pair of pivoting shafts 262, it will be obvious that the pair of pivoting grooves 251 should be spaced apart from each other.

Subsequently, since the rotation frame 260 performs a wire relay function, a wire is installed in the main body 261, and a power core 252 is provided in the rotating groove 251 to conduct electricity with the wire in the support 250. The insertion shaft 262a is formed in the rotation shaft 262 to which the power core 252 is inserted. As a result, when the rotation shaft 262 is inserted into the rotation groove 251, the power shim 252 is inserted into the insertion groove 262a, through which the wires connected to the power shim 252 and the main body 261 are installed. The wires are energized with each other. For reference, the electric wire in the support 250 is connected to one pole of the DC power supply (B), the other pole is connected to the other rotating shaft forming a pair, so that the positive polarity of the DC power supply (B) To be expressed in the pair of bearings 264. Meanwhile, the DC power source B may be a conventional 12V or 24V rechargeable battery provided separately.

The seating table 263 may have a groove shape having an upper surface, and a pair of the mounting table 263 may be disposed to face the body 261 so as to cross at a right angle with the pair of pivot shafts 262.

Figure 5 is a cross-sectional view showing a state of a bearing that is one configuration of the rotating frame according to the present invention, it will be described with reference to this.

The bearing 264 supports the case 270 so as to be smoothly rotated while being fixed to the mounting table 263, and includes a base 264a, a roller 264b, a rotator 264c, a friction 264d, and an electrode. It consists of a sieve 264e.

In more detail, the base 264a has a circular arc shape and is firmly fixed to the pair of seating posts 263, respectively.

A plurality of rollers 264b are rotatably fixed along the base 264a and are made of a material having a large coefficient of friction.

The rotator 264c has an arc shape facing the base 264a, and the bottom face facing the base 264a is engaged with the roller 264b, so that the base 264a is shown in Fig. 5C. It will be able to move independently in concentric circles. On the other hand, the rotator 264c is made of a conductive material.

The friction ruler 264d is applied to the bottom surface of the rotator 264c facing the roller 264b to increase the engagement efficiency between the roller 264b and the rotator 264c, and the friction coefficient is considered in consideration of the material of the roller 264b. It would be desirable to apply a large material.

The electrode body 264e is a wire which is finally connected to the main body 261, and is disposed below the rotator 264c, and the rotator 264c immediately above the electrode body 264e is positioned in a flexible material. When the rotating shaft 271 of the case 270 is pressurized, it is deformed and bent to be joined to the electrode body 264e. That is, when the rotation shaft 271 is seated on the seating table 263, the electricity is supplied to the rotator 264c and the electricity can be supplied to the rotation shaft 271.

In more detail, as shown in FIG. 5A, the electrode body 264e is disposed between the friction 264d and the rotator 264c while being spaced apart from the rotator 264c, and includes a rotating shaft. The electrode body 264e is located below the lowest point of the arc-shaped rotator 264c so that the pressurization efficiency of 271 can be sufficiently transmitted to the rotator 264c and the electrode body 264e. For reference, in order to achieve the above-described structure, the friction ruler 264d applies one surface of the rotator 264c in contact with the roller 264b, but is spaced apart from a corresponding point at which the electrode body 264e is positioned, so that only when the pressure is applied. The electrode body 264e and the rotator 264c can be joined.

Subsequently, as shown in FIG. 5B, when the rotating shaft 271 is seated on the seating table 263, the rotator 264c is bent by the load of the case 270 or the like, thereby causing the electrode body 264e. And the rotator 264c spaced apart from each other are electrically energized while being in mechanical contact with each other. Here, in order to increase the contact area between the electrode body 264e and the rotator 264c, it is preferable to form wrinkles on the surface of the electrode body 264e, and correspondingly, wrinkles are also formed on the corresponding surface of the rotator 264c. Do.

On the other hand, when the rotating shaft 271 is separated from the seating table 263, the load applied to the rotator 264c is lost, so that the rotator 264c is restored to a circular shape, and as a result, the contact with the electrode body 264e is released, thereby causing the rotator ( 264c) is disconnected.

6 is an exploded perspective view illustrating an anchor bar of the reference point display device according to the present invention, FIG. 7 is a plan view sequentially illustrating an installation process of the reference point display device according to the present invention, and FIG. 8 illustrates an operation of the anchor bar. It is a schematic cross-sectional view, it will be described with reference to this.

The case 270 accommodates the signal detector 220, the charger 230, and the driver 240, and is detachably fixed to the rotation frame 260 while mounting the laser 210 on the upper surface. To this end, the case 270 protrudes from each other to form a pair of rotation shafts 271 that are seated on the seating table 263 of the rotation frame 260. Here, the rotating shaft 271 is formed with a conductor 271a around the conductive material so as to energize the contact with the rotator 264c made of a conductive material, the conductor 271a is a laser 210, a signal sensor 220, a charger 230 And wires to supply electricity for the operation of the driver 240. For reference, since the laser 210, the signal detector 220, the charger 230, and the driver 240 operate independently of each other, electrical connection must be made in parallel with each of the conductors 271a of the pair of rotating shafts 271. something to do.

 On the other hand, in the case of a situation in which the information update of the digital map is required due to the change of the terrain, and this requires aerial photography, the laser support 210, the case 270 and the anchor bar separated from the support 250 installed at the reference point are stored. Equipment such as 280 should be installed on the support 250. Such installation work should be carried out by a non-expert, but since the installation work is all to seat the case 270 on the rotation frame 260 of the support 250, it can be said to be very easy.

The process of connecting the case 270 to the rotation frame 260 will be described in more detail. The laser 210 penetrates upward to the horizontal rotation frame 260. At this time, since the length of the rotation shaft 271 formed in the case 270 is longer than the width of the rotation frame 260, as shown in Figure 7 (a), the rotation shaft 271 of the rotation frame 260 After passing in the diagonal direction, when it is confirmed that the rotating shaft 271 has sufficiently penetrated the rotation frame 260, as shown in FIG. 7 (b), the case 270 is rotated so that the rotating shaft 271 is a seating table. To (263).

Anchor bar 280 is a screw pipe (282a to 282e) is formed on the inner surface and the outer surface and the plurality of different diameters are interlocked with each other in a row, and the coaxial tube (283a to 283e) connected by inserting a plurality of pipes in a row ) And a weight 281 provided at the lower ends of the screw pipes 282a to 282e.

The screw pipes 282a to 282e have threads formed on the inner surface and the outer surface as shown in the drawing, and a plurality of threads having different diameters are threaded connected to each other in a line, so that the neighboring screw pipes along the rotational direction of the screw pipes 282a to 282e. 282a to 282e are to be loosened or tightened, through which the length of the anchor bar 280 is adjusted. For reference, the screw pipes 282a to 282e having the largest diameter are fixed to the bottom surface of the case 270 via the flange P.

Coaxial pipes (283a to 283e) is a plurality of pipes are connected in a row in a detachable manner, to form a column shape so that the rotational force can be transmitted to the neighboring coaxial pipes (283a to 283e), screw pipe (282a to 282e) Is implied. On the other hand, the coaxial tube 283e located at the bottom end is connected to the screw pipe 282e located at the bottom, so that the rotational force of the coaxial tubes 283a to 283e can be transmitted to the screw pipes 282a to 282e. As a result, when the coaxial pipes 283a to 283e rotate, the rotational force is first received and rotated by the screw pipe 282e located at the bottom, and along the threads of the second screw pipe 282d threaded to the screw pipe 282e. As they move, they are released or tightened.

Subsequently, when the lowermost screw pipe 282e moves along the second screw pipe 282d and can no longer be loosened or tightened, the rotational force is transmitted to the second screwpipe 282d and the second received rotational force is transmitted. The screw pipe 282d rotates along with the screw pipe 282e located at the bottom thereof and is loosened or tightened while moving along the thread of the third screw pipe 282c.

As the rotation continues, a plurality of screw pipes 282a to 282e connected to each other are formed to have the shortest or longest length while fully tightened or loosened as shown in FIG. 8 (a) or 8 (b).

In the anchor bar 280 of the reference point display device 200 according to the present invention, when the case 270 is seated on the pivot frame 260, the polarity direction of the DC voltage supplied from the DC power source B is 8 (b). As shown in FIG. 6, the polarity direction of the DC voltage supplied from the battery of the charger 230 is increased when the switch 241 is operated after removing the case 270 from the rotation frame 260. As shown in Fig. 8 (a), the length becomes shorter along the longitudinal direction.

On the other hand, the weight 281 disposed at the bottom of the anchor bar 280 concentrates the center of gravity of the anchor bar 280 at the bottom, the case 270 is a horizontal axis to the support 250 by the rotation shaft 262 Since the rotating frame 260 and the rotating shaft 271 is fixed to be rotated by the longitudinal axis, the pendulum is moved in various directions, so that the case 270 is a laser (regardless of the arrangement of the support 250). It is possible to aim 210 directly upright.

The light emitter 290 irradiates the reference laser light toward the light receiving panel 255, and is installed in the weight 281 for irradiating the reference laser light to the light receiving panel 255 disposed below the anchor bar 280. . Accordingly, the reference laser light is irradiated toward various points of the light receiving panel 255 while moving along the rotation of the anchor bar 280.

For reference, the stopper 254, the light receiving panel 255, and the light emitter 290 may be mounted on their own power source or may be supplied collectively through a separate battery. The power source may be continuously supplied without additional control. The amount of charge will be sufficient to drive the aerial shooting from start to finish.
