(2 D) map image is shown based on the image obtained by using the aircraft, and the corresponding position information (coordinate information) is recorded at each position and utilized as an electronic map. In recent years, In addition, moving the field of uncertain terrain under development to a vehicle, etc., a direct image was acquired and a 3D image map was created by combining the acquired image and the corresponding coordinate information. It is general to synthesize by a processing system.

Since the video images obtained by using the aircraft and the uncertain areas are transferred to the vehicles while securing the image images, it is necessary to precisely synthesize the corners or the ends of the road or the feature when synthesizing the stereoscopic image map, In order to perform synthesis processing, precise position information (coordinate information) is required, and at the same time, an uncertain image of a scene must be accurately shot without error.

As the technology related to image processing is developed, more realistic and precise three-dimensional map can be made.

FIG. 4 is a partial cross-sectional perspective view of a video camera module according to an embodiment of the present invention, and FIG. 5 is a perspective view of a video camera module according to an embodiment of the present invention, 6 is a functional block diagram illustrating the precision position information detector according to an embodiment of the present invention.

The image processing system 1 having improved image image accuracy includes an air image providing unit 10, a precision position information detecting unit 30, a vehicle 50, A synthesizing apparatus 70, an image processing control unit 90, and a videoless video camera unit 100. [

The aerial image providing unit 10 is connected to the image processing control unit 90. The aerial image providing unit 10 forms a database (DB) in the allocated area, which is a two-dimensional (2D) plane image of the ground surface, (Coordinate information), and outputs or provides the corresponding position information (coordinate information) according to a corresponding control signal of the image processing control unit 90. Hereinafter, the aerial image captured is a two-dimensional plane image Describe as an image.

The precision position information detection unit 30 is installed on a front side of the roof part of the vehicle 50 and is connected to the image processing control unit 90 to perform communication for transmitting and receiving the signals.

The precision position information detection unit 30 receives and analyzes the GPS signal received from the GPS satellite and outputs coordinate information (position information) including a moving direction, a moving speed, a sea level, a longitude, a latitude, And is composed of one or more and two or more pieces of the laser ray receiver 310. In the drawings, three are shown, but it is quite natural that the number of laser ray receiver units can be reduced to two or more.

The precision positional information detecting unit 30 is preferably installed in the same position as or adjacent to the zero motion video camera unit 100 and is operated in order to reduce the error. In other words, it is preferable that the precise position information detection unit 30 and the zero motion video camera unit 100 are installed in the same vehicle 50.

The precision position information detection unit 30 includes an antenna unit 300 and a rotation driving unit 400.

The antenna unit 300 includes one or more antennas on an upper surface of a flat plate and receives GPS signals. The antenna unit 300 includes one or more GPS receiver units (not shown) for receiving GPS signals and detecting current position information 310 and a flat plate disk 320 fixedly mounted on a concentric circle with an equal angle to the upper surface of the flat disk.

The antenna unit 300 includes three pieces of the GPS receiver units 310 on the flat plate disc 320 of the same plane in order to increase the precision of positional information (coordinate information) wirelessly received and analyzed from the GPS satellite.

The GPS receiver 310 receives and analyzes the GPS signal and detects position information or coordinate information including the current altitude, latitude, longitude, time, and the like.

The three laser ray receiver units 310 provided on the plate plate 320 are arranged on the same circumference from the central axis of the plate plate 320 and are arranged at 120 degree intervals which are equiangularly (at the same angle).

The position information (coordinate information) detected by the three laser-receiving units 310 constituting the precision position information detecting section 30 is provided to the image processing control section 90 and is subjected to arithmetic mean calculation by the image processing control section 90, (Coordinate information) value. Since the arithmetic mean calculation method is well known, a detailed description thereof will be omitted.

The image processing control unit 90 calculates arithmetic average of the position information (coordinate information) detected by each of the three pieces of the dust receiver units 310 so that the position information (coordinate information) A precise value of more than a multiple is output. When the number of constituent elements of the digital watermark reception unit 310 is increased or decreased, a precise value is output in the corresponding multiple.

The rotation driving unit 400 periodically generates rotational power of left and right rotations by the corresponding control signal and transmits the generated rotational power to the rotation center axis of the antenna unit 300 to rotationally drive the plate plate 320 so as to turn left or right. A driven gear 420, a driven gear 430, a driven gear shaft 440, a hollow motor shaft 454, a rotary motor 450, and a fixed bracket 460. [

The disk rotation axis 410 has a circular rod shape, and one end of the disk rotation axis 410 is fixed to the rotation center axis of the plate disk 320.

The disk rotating shaft 410 is fixed by welding at the position of the rotation center axis of the plate disk 320. If necessary, a male screw is formed on the outer circumferential surface of one end and a female thread is formed at the rotation center axis position of the disk disk 320, And can be fixedly bonded by bonding. In this case, the male screw portion and the female screw portion are formed in a structure and a shape corresponding to each other.

That is, the disc rotating shaft 410 is fixed downward at the rotational center axis position of the disc original disc 320, and has a round bar shape, and transmits the rotational power of left or right turning to the original plate 320.

The driven gear 420 is fixed to the other end of the disc rotation axis 410 and forms teeth on the outer peripheral surface of the disc-shaped edge.

The other end portion of the disc rotation axis 410 is fixed by welding to the rotation center axis position of the driven gear 420. If necessary, a male threaded portion is formed on the other side peripheral surface of the disc rotation axis 410, The female screw portion may be formed at the central axial position and fixedly coupled by screwing. In this case, the male screw portion and the female screw portion are formed in a structure and a shape corresponding to each other.

That is, the driven gear 420 is fixed to the lower end portion of the disk rotation axis 410 and has a circular sawtooth structure in which a tooth is formed on the rim of the disk, and the disk rotation axis 410 is provided with a rotation power And the disk rotating shaft 410, the driven gear 420, and the plate disk 320 are fixed to each other. Therefore, when one of them rotates, the whole disk rotates in the same manner.

The driven gear 430 is formed in a circular bar shape perpendicular to the rotation axis of the driven gear 420 and the helical teeth formed on the outer peripheral surface correspond to the teeth formed on the outer peripheral surface of the driven gear 420).

That is, the main gear 430 has a cylindrical shape and a rod-shaped outer peripheral surface having a length corresponding to the driven gear 420. The formed gear has a spiral shape, and the main gear 430 and the driven gear 420 ) Are driven so that the gears are meshed with each other in a state where the axes are orthogonal to each other.

The main gear shaft 440 has a round rod shape in which one end of the main gear shaft 440 is fixed to the rotating shaft of the main gear 430 and the male screw portion 442 is formed on the outer peripheral surface of the other end.

That is, the main gear shaft 440 has a circular bar shape, and one end of the main gear shaft 440 is fixed to the rotating shaft portion of the main gear 430 and the other end of the main gear shaft 440 is formed with a male screw portion 442. It transmits the turning power of the right turn.

The main gear shaft 440 is fixed by welding at the rotational center position of the main gear 430. If necessary, a male screw portion is formed on the outer peripheral surface at one end and a female screw portion is formed at the rotational center shaft position of the main gear 430 It can be fixedly connected by screwing. In this case, the male screw portion and the female screw portion are formed in a structure and a shape corresponding to each other.

The main gear 430 and the driven gear 420 are connected to each other through a worm gear system and the power is transmitted from the main gear (worm) having a relatively small number of teeth to the driven gear (worm gear) having a relatively large number of teeth .

Since the reduction gear ratio of the gears 430 and 420 is relatively large, the rotation of the plate disk 320 can be stabilized and the rotation motor having a small size or a small output can be used .

Further, connecting the main gear 430 and the driven gear 420 by a worm gear method takes advantage of a relatively small area, which can reduce the overall size of the system.

The gear reduction ratio of the driven gear 420 to the driven gear 430 can be in the range of 1 to 10 to 1 to 20, and the gear reduction ratio of 1 to 15 can reduce the rotation torque .

The hollow motor shaft 454 internally defines a female threaded portion 452 corresponding to the male threaded portion 442. It is very natural that the female screw portion 452 has a shape corresponding to the male screw portion 442. After the male screw portion 442 is screwed and fastened to the female screw portion 452, It is explained that the fixed state in which the male screw portion 442 and the female screw portion 452 are fastened by screw engagement is maintained.

The rotation motor 450 incorporates the hollow motor shaft 454 in a rotated state and causes the hollow motor shaft 454 to turn left or right by the corresponding control signal applied from the image processing controller 90.

The fixing bracket 460 is formed on the outer surface of the rotation motor 450 so as to protrude in both directions in a straight line, and a bolt hole 462 through which the bolt is inserted is formed.

That is, the rotation motor 450 is configured to rotate left or right at a rotation speed designated by the control signal applied from the image processing control unit 90. The rotation motor 450 has a hollow motor shaft And a bolt hole 462 is formed at one side of the fixing bracket 460 to fix the rotation motor 450 to the fixing bracket 460 in a straight line and in both directions.

Here, the operation state of the image processing control unit 90 will be described. In an embodiment, if the image processing control unit 90 determines that the operation of the image processing system 1 that has improved the accuracy of the image image is started, The control unit 450 repeatedly outputs the control signal so that the rotation motor 450 turns the current rotation direction to the opposite direction and rotates every time the distance of the set unit standard is shifted.

It is quite natural that the direction in which the rotation motor 450 starts to rotate in the initial stage is irrelevant in either the left-turn direction or the right-turn direction.

If the image processing control unit 90 judges that the operation of the image processing system 1 that has improved the accuracy of the image image is started, 450 repeatedly outputs the corresponding control signal so as to switch the current rotation direction to the opposite direction.

That is, the image processing system 1, which improves the accuracy of the image, increases the rotation speed of the original plate 320 every unit movement distance or unit elapsed time, And is outputted from the control unit 90 to the rotating motor 450.

Periodically changing the rotating direction of the flat plate master 320 periodically changes the position of the at least one of the plurality of the laser ray receiver units 310 installed on the same circumference of the flat plate master 320 so that each of the laser ray receiver units 310 receives To be received under the same condition.

That is, when one of the paper-feed receiver 310 receives the paper-feed signal at a relatively low position and the other paper-feed receiver 310 receives the paper-and-paper signal at a relatively high position, It is general that the position information (coordinate information) analyzed and received by the receiving unit 310 may be different. However, when the position is periodically changed, this error is reduced, and more precise position information (coordinate information) can be calculated.

Since the image processing control unit 90 analyzes the positional information (coordinate information) provided from the accurate positional information detection unit 30, the video image photographed by the noiseless moving image camera unit 100 is previously photographed from the aircraft and is provided in a stored state Which part of the two-dimensional image of the ground corresponds to which part.

Therefore, as the value of the position information (coordinate information) detected from the precise position information detection unit 30 is more precise, the precise three-dimensional image image without errors is converted into the three-dimensional image image processed by the image-image precise synthesizer 70 .

The vehicle 50 includes the aerial image providing unit 10, the precise position information detecting unit 30, the image precision synthesizing unit 70, the image processing control unit 90, and the zero motion video camera unit 100, Describe that it is similar to a typical vehicle by driving on roads or unoccupied roads or areas where uncertain features are located.

The image-image-precision synthesizing apparatus 70 synthesizes a two-dimensional image image photographed by the control signal of the image processing control unit 90 and a local image photographed locally on the ground to obtain a three-dimensional image image Converts or generates image processing.

The image-image precise synthesizing apparatus 70 includes an aerial photographing image image received via the image processing control unit 90 by the corresponding control signal of the image processing control unit 90, Or the boundary portion of the road, the image image provided by photographing the actual site is synthesized using the precise position information provided by the precise position information detection unit 30, so that the end portion and width of the road by the image image, Into a precise three-dimensional (3D) video image of a matching size.

The image image precise synthesizer 70 receives precise position information and precise position information of the start and end portions photographed in an uncertain feature of the ground, and displays the precise position information at a corresponding position of the map produced by the image image.

An apparatus and a method for image processing a two-dimensional aerial photographic image and a video image (including a moving image) photographed by the non-video camera unit 100 to synthesize (transform) a three-dimensional image are well known to those skilled in the art A detailed description will be omitted.

The image processing control unit 90 is connected to the aerial image providing unit 10, the precise position information detecting unit 30, the image precise synthesizing unit 70 and the zero motion video camera unit 100, The operation of each constituent unit will be described by describing the operation of the constituent unit, and further explanation will be given when necessary.

The motionless video camera unit 100 includes an image camera unit 500 and a vibrationless unit 600. The motionless camera 100 includes a precise position information detecting unit 30 installed on a front side of a roof of the vehicle 50, We shoot both the beginning and end of water, roads and buildings.

The image camera unit 500 includes a camera unit 510, a housing unit 520, and a lower leg 530.

The camera unit 510 is relatively expensive due to the fact that the camera unit 510 photographs a subject or an uncertain feature, a road, a building, or the like using a corresponding control signal of the image processing controller 90 as a high-magnification and high-

The housing part 520 is in the form of a box or a cylinder and protects the camera part 510 from an external force or an external impact and is shown in the form of a rectangular tube in the drawing. However, the housing part 520 may have a circular shape or other polygonal shape, It is quite natural that the shape can be formed in a polygonal shape. Here, external or external impacts include snow, rain, wind, chemical impact, physical impact, mechanical impact, and electromagnetic impact.

The lower leg 530 is provided at the lower end of the housing part 520 to fix the housing part 520 to a flat part. In the figure, the lower leg part 530 is shown as a circular bar shape, but it is formed in a triangular shape, a square shape, It is quite natural to be able to.

Although only three non-vibration parts 600 are shown on the lower side of the image camera part 500 in the accompanying drawings, the illustration is omitted for easy understanding and for facilitating the illustration, 600) can be installed in a number of one, two, three, or four or more as necessary. In other words, five or more can be installed in a terrain with poor road conditions such as a mountainous terrain or an uncertain terrain, or three or less in a terrain with good road conditions such as a city center.

The vibration deadening unit 600 includes a coupling hole 610 fixedly coupled to the lower end of the lower leg 530 and an upper plate 622 coupled to a lower surface of the coupling hole 610 and a lower end extending downward from an edge of the upper plate 622, A casing 620 having an opened cylindrical portion 624 and an inwardly directed flange portion 626 formed inside the lower end of the cylindrical portion 624 and an inwardly directed flange portion 626 inserted into the casing 620, A shock absorbing packing 640 which is engaged with the edge of the lifting plate 630 and whose lower end is in contact with the inward flange portion 626 and whose outer circumferential surface is not in close contact with the inner peripheral surface of the cylindrical portion 624, A second upper plate portion 652 inserted between the lower plate portion 620 and the lifting plate 630 and abutting the lower surface of the upper plate portion 622 and a second lower plate portion 654 abutting the upper surface of the lifting plate 630, A shock absorbing tube 650 having a corrugated tube portion 656 connecting the edge of the first lower plate portion 652 and the edge of the second lower plate portion 654, A compression coil spring 660 whose upper end is in contact with the second upper plate portion 652 and whose lower end is in contact with the second lower plate portion 654 and a shock absorbing member 670 which is filled in the compression coil spring 660 And a lower end impact absorbing pad 680 coupled to the lower surface of the steel plate 630.

The shock absorbing tube 650 and the lower end impact absorbing pad 680 are made of a natural rubber material or a rubber material, And the shock absorbing member 670 may be made of a material used as a dust-proof pad such as a dust-proof sponge, a urethane sponge, or the like in which a large amount of air bubbles are formed.

The lower leg 530 is inserted into the coupling hole 610 and fixed to the coupling hole 610 by one or more coupling screws 612.

It is quite natural that the coupling hole 610 and the upper plate portion 622 of the casing 620 can be fixedly coupled by welding and fixedly coupled using a bolt and a nut.

The steel plate 630 and the lower end impact absorbing pad 680 can be fixedly connected using a screw connection, a known partial interference fit or an adhesive.

On the other hand, the lower impact absorbing pad 680 is fixed to a designated place on the upper surface of the vehicle 50 or a front portion of a ceiling (shown by a roof in the figure) with screws or a separate bracket. Such a mounting method is generally known, so a detailed description thereof will be omitted.

The thickness or the height value of the lower impact absorbing pad 680 is set to 1/2 to 1/5 of the height value of the casing 620, It is desirable to buffer.

On the other hand, the lower impact absorbing pad 680 may be configured to absorb the external shock and vibration by being filled with air in an airtight state.

Since the lower impact absorbing pad 680 is fixed to the roof of the vehicle 50, the video camera 100 is fixedly installed on the roof of the vehicle in a non-vibration state.

The casing 620 is formed by pressing a metal plate to form an upper plate portion 622 and a cylindrical portion 624 and an extension portion for forming an inward flange portion 626 at the lower end of the cylindrical portion 624 The steel plate 630 having the shock absorbing tube 650, the compression coil spring 660, the shock absorbing member 670 and the buffer packing 640 fitted in the rim is inserted into the casing 620, The extension portion temporarily formed at the lower end of the flange portion 624 may be bent inward to form the inward flange portion 626. [

The buffer packing 640 is formed in a 'C' shape in cross section and is coupled to an edge (rim) of the lift plate 630.

When a shock applied from a road or an ordinary road of an uncertain feature or a vibration applied from a vehicle is applied to the missing video camera unit 100, The vibration is transferred to the lower leg 530 through the absorbing pad 680, the steel plate 630 and the casing 620 and the coupling hole 610. The impact and vibration are primarily buffered by the lower end impact absorbing pad 680, Shocks and vibrations are absorbed and buffered by the shock absorbing tube 650, the compression coil spring 660 and the shock absorbing member 670 in the process of passing through the steel plate 630 and the casing 620, The shock applied or the vibration applied from the vehicle 50 is prevented from being transmitted through the lower leg 530 to the housing part 520 and the camera part 510 mounted thereon.

The buffer packing 640 is fitted to the edge of the lifting plate 630 and the lower end of the buffer packing 64 abuts against the inward flange portion 626 and the outer circumferential surface of the buffer packing 64 abuts against the inner peripheral surface of the cylindrical portion 624 The impact or vibration transmitted without being absorbed by the lower impact absorbing pad 680 is absorbed and buffered between the lifting plate 630 and the casing 620 and is thus annihilated.

The above-described construction precisely secures a video image of an uncertain feature by the video camera unit 100 fixed on the roof of the vehicle, and precisely detects the location information Coordinate information), and the image-image precise synthesizer 70 has a merit of accurately performing synthesis image processing without error in a three-dimensional image.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
