Description

3D image system synthesizing the private picture image in editting the digital aerial photography information}

The present invention relates to a three-dimensional image drawing system for synthesizing three-dimensional drawing images by editing the digital aerial photography information for each object.

With the development of geographic information technologies such as GPS and GIS based on them, the location information supplied through these is being positioned as essential information in human life.

The most widely used geographic information technology for the general public is location tracking technology, such as a navigation terminal installed in a vehicle or owned by a user, so that a user can easily understand the location by tracking his or another person's location. It is preferable that the drawing technique be applied in parallel. This is because the location information that the GPS confirms and outputs the user's location is only a numerical value, so that the user cannot estimate his / her own location using the location information alone, but the image corresponds to the numerical value in the drawing image captured by the air vehicle. This is because the user can compare the content of the drawing point with the content of the drawing image when the user outputs the marked point, so that the user can accurately understand the current location.

On the other hand, through the continuous development of drawing image, it is now possible to output the three-dimensional topography. That is, the user can accurately check his or her location by tracking the location of the drawing image close to the photorealistic image.

However, since the drawing image is composed of an artificially constructed stationary structure and a naturally formed stationary terrain, a flexible structure such as a large ship cannot be represented in the drawing image. Of course, due to this limitation, the user who passes near the coastal / coastal road or harbor has a problem that can not be confirmed through the navigation, even though there is a ship in the vicinity.

Accordingly, the present invention has been invented to solve the above problems, and independently separate and edit only the vessel which is a specific object from the drawing image produced on the basis of the aerial photographing information, so that the user can obtain more realistic location tracking information. The technical task is to provide a stereoscopic image drawing system for synthesizing three-dimensional drawing images by editing digital aerial photographing information to be provided for each object.

At this time, when the drawing system according to the present invention is applied to the navigation, the ship image (SI) of the ship 2 in operation in the adjacent position of the vehicle 1 is output on the output screen (31). In addition, since the navigation system with the drawing system according to the present invention keeps track of the movement of the ship 2, the operation state of the ship 2 is displayed on the output screen 31 as it is. Of course, the user can feel the reality of the drawing image through the output screen 31, it is possible to more easily understand the position confirmation of the user image (MI) output from the output screen (31).

In order to achieve such a function, the drawing system according to the present invention is provided with a plurality of transmitters 10 along the periphery of the ship 2. Here, the transmitter 10 outputs an analog signal having the same intensity including its own identification code, and the processing means 20 of the navigation device installed in the vehicle 1 receives and identifies the analog signal and sets its position. Check it. For reference, since the transmitter 10 according to the present invention transmits an analog signal including an identification code, a conventional transmitter such as a D / A converter and an amplifier for a constant signal output is configured. Since the configuration of the transmitter 10 is well-known and public technology, a detailed description of the configuration is omitted here.

Subsequently, a plurality of transmitters 10 are installed along the periphery of the vessel 2, one leading transmitter 11 is installed at the head of the vessel, and two tail transmitters 13 and 13 'are arranged to be symmetrical at the rear. ) Is installed. In addition, a pair or two or more pairs of side transmitters 12 and 12 'are installed on the side of the ship 2 so as to be symmetric with each other.

Each transmitter 10 installed in this way continuously transmits an analog signal, and all transmitters 11, 12, 12 ', 13, 13'; '10' when all refer to the transmission strength of the analog signal is the same, The processing means 20 according to the present invention may calculate the distance and direction between the vehicle 1 and the transmitter 10 by using the received direction, time difference, and intensity difference of the received analog signals, and the distance thus confirmed.

FIG. 6 is a view illustrating a ship image that is output by correcting abnormal reception contents of FIG. 5. Explain.

S10; Send Step

The head transmitter 11, the side transmitters 12 and 12 'and the tail transmitters 13 and 13' provided at the head, the side and the tail of the ship 2 respectively transmit analog signals at the same time and interval. The analog signal is a conventional signal format including an identification code as mentioned above, and the strength of the analog signal originally transmitted from all transmitters 10 is the same.

For reference, the head transmitter 11 of one of the transmitters 10 installed on the ship 2 is installed at the head of the ship 2, and the side transmitters 12, 12 'are minimum on the side of the ship 2; One or more pairs are installed at points symmetrical to each other, and the tail transmitters 13 and 13 'are installed at points at which the pair is symmetrical to the rear of the ship 2.

S20; Signal processing

The receiving module 21 of the processing means 20 installed in the vehicle 1 receives the analog signal of the transmitter 10, converts the analog signal into a digital signal through A / D conversion, and confirms the identification code. Here, the identification code should be largely divided into an identification code of the first transmitter 11, an identification code of the side transmitters 12 and 12 ', and an identification code of the tail transmitters 13 and 13', but a pair of side surfaces. Each of the transmitter 12, 12 'and the tail transmitter 13, 13' can be unified with the same identification code. For example, while the analog signal transmitted from one or two or more pairs of all the side transmitters 12 and 12 'includes the same identification code, the processing means 20 according to the present invention is capable of transmitting the analog signal. If it can be confirmed that it is made from the side transmitter (12, 12 ') is sufficient. This is to minimize the processing delay and overload of the system in the process of confirming and processing a plurality of identification codes, it can also be expected to reduce the cost of manufacturing the transmitter 10.

Subsequently, the receiving module 21 checks the strength of the analog signal and calculates the distance between the transmitter 10 and the vehicle 1 which transmitted the analog signal. As mentioned above, since the analog signal is transmitted from the transmitter 10 at the same strength as promised to each other, the receiving module 21 can calculate the distance based on this.

Subsequently, the receiving module 21 checks the reception direction of the analog signal and tracks the position of the transmitter 10 which has transmitted the analog signal. However, since the technique of tracking the point at which an analog signal is transmitted is a publicly known or public technology of a conventional receiving module 21 having a radar function, the description of the electronic components mounted on the receiving module 21 and the operation of the circuit will be described here. Detailed description thereof will be omitted.

S30; Outline line drawing step

The analysis module 22 analyzes the identification code of each of the transmitters 10 transmitted from the reception module 21 and the information about the position and the distance, and performs the outline drawing for ship image SI.

The analysis module 22 checks the leading point SF, the side points SS1 and SS2 and the tailing points SE1 and SE2 using the identification code, the position and the distance, respectively. (SF) and trailing points (SE1, SE2) are correctly distinguished.

Subsequently, the leading point SF, the side points SS1 and SS2 and the tail points SE1 and SE2 are determined based on the user image MI to be output on the output screen 31, and the outer lines are connected in a line. Confirm.

S40; Symmetry Check Step

Since the plurality of transmitters 10 installed along the periphery of the vessel 2 are all located at different distances and directions with respect to the vehicle 1, the perimeter line determined by the analysis module 22 if there is no interference of signal transmission. Will be expressed in a symmetrical form, through which the outer line will be utilized as the ship image (SI).

In more detail, the analysis module 22 connects the midpoint P between the pair of stern points SE1 and SE2 and one leading point SF to generate a central axis L, Check the intersection point C between the pair of side points SS1 and SS2 and the central axis L, and if the distances between the side points SS1 and SS2 and the intersection point C coincide with each other as shown in FIG. The outline line is determined as a ship image (SI), and if it does not coincide with each other as shown in FIG. 5, the modification process of the outline line is performed. Here, the symmetry of the outer line does not have to perfectly match the distance between each side point (SS1, SS2) and the intersection point (C), and if the difference of the distance is within the range by setting a range for a certain ratio, the corresponding outer By looking at the lines symmetrically, you may decide to confirm with the ship image (SI).

When the vehicle 1 travels on a relatively high road and the plane of the ship 2 is exposed as it is, the analog signal of the transmitter 10 installed outside the ship 2 can be transmitted to the receiving module 21 without interference. have. However, when the ship 2 is large and the analog signal of the transmitter 10 installed at the edge of the deck is covered by the central body, the transmission of the analog signal is disturbed by the central body, thereby receiving the reception module 21. The intensity of the analog signal of the corresponding transmitter 10 that is received by) may decrease. In addition, the analog signal may be affected by the transmission speed due to the interference of the central body, so that the reception time of the reception module 21 may be further delayed. As a result, the outline lines drawn by the analysis module 22 under such conditions form a shape as shown in FIG. 5.

 By the way, it is clear that the outer line shown in Figure 5 is not suitable as the ship image (SI).

In more detail, as described above, the center axis (L ') connecting the midpoint (P') and the leading point (SF) between the tail point (SE1 ', SE2) is identified, and the side point ( Checking the intersection C 'between the connecting line between SS1' and SS2 and the central axis L ', it is clear that the distances between the side points SS1' and SS2 and the intersection C do not coincide with each other. This clearly shows that the periphery line does not accurately image the ship image (SI).

Therefore, the correction work of the outer line shown in FIG.

For reference, since the analog signal of the head transmitter 11 installed at the head is not disturbed due to the structural characteristics of the ship 2, the drawing system according to the present invention ignores the error with respect to the head point SF. In addition, two tail transmitters 13 and 13 'are installed at the rear of the ship 2 instead of one, so that the tail transmitters 13 and 13' can receive at least one analog signal transmitted from the tail transmitters 13 and 13 '. .

S50; Adjacent point check step

In the symmetry check step (S40), if it is confirmed that the outline line drawn by the analysis module 22 is not suitable as the ship image (SI), the correction module 27 is the leading point (SF) and the side point (SS1, SS2) At and after the tail points SE1 and SE2, the leading point SF as well as the side points SS1 'and SS2 and the side points SS2 that are relatively closer to the user image MI among the tail points SE1' and SE2. And end point (SE2).

Subsequently, since the transmitter 10 simultaneously transmits analog signals at regular intervals, the receiving module 21 receives the next analog signal, and the analysis module 22 shows the changed leading point SF 'as shown in FIG. 6. Check).

The correction module 27 forms a correction central axis L "connecting the previous leading point SF and the changed leading point SF '.

S60; Symmetric drawing step

The correction module 27 draws a correction outline line symmetrical with respect to the outline line connecting the adjacent side points SS2 and the tail point SE2 with respect to the correction center axis L ″.

S70; Background image composition drawing step

The GPS 24 checks the GPS position of the vehicle 1, and the synthesizing module 23 searches the image DB 25 for the background image linked to the GPS position, and the ship image SI according to the modified outline line. ) Is combined with the background image.

On the other hand, since the vessel image (SI) completed according to the above process is drawn only along the outer line of the vessel (2), the schematic shape appears to be a vessel image, but the shape and three-dimensionality of the central body at the time of vessel image drawing are not considered. Thus, the realism may be somewhat lacking. In order to solve this problem, the compositing module 23 synthesizes and applies a random central body image to the ship image so that the complete ship can be expressed. When the user adjusts the drawing image in 3D, the height of the ship image is adjusted. In this way, the ship image SI can be represented in 3D according to the adjustment.

S80; Output stage

The completed drawing image is transmitted to the output means 30, and the output means 30 processes the data related to the drawing image by a conventional technique and outputs it through the output screen 31.

On the other hand, the calculation module 26 can check the processing contents of the GPS 24 according to the movement of the vehicle 1 to calculate the speed of the vehicle 1 and the like, and the synthesis module 23 calculates the speed thus calculated. The information is combined with the drawing image and output as shown in Fig. 1 (b).
