Description

Spatial image drawing system capable of precisely drawing symmetrical features using image images

The present invention relates to a spatial image drawing system, and more particularly, to a space image drawing system capable of precisely drawing a symmetrical feature using a video image.

With the development of computers and software, the development of precision optical machines and laser measuring devices, etc., digital map production has become possible, and related technologies have been steadily developed, and conventional analog map production is rapidly changing to digital map production.

In cartography, drawing refers to the work of drawing a 2D or 3D image map based on geographic information, and with the development of digital output technology, it has recently become possible to draw a digital image or 3D graphic image. It is also called spatial video painting in the sense that it is like a real picture.

In this way, with the development of spatial imagery technology, more realistic and precise map production became possible, and it became easier to update spatial imagery information according to changes in topography and geographic information.

With this development, geographic information is widely used as popular information today, and its accuracy and update efficiency are greatly improved, and it is widely applied in various fields as useful information with high reliability for its utilization.

The process of drawing and processing aerial photographed image information can be said to be the most important factor in the production of digital maps. , Currently, 1/20,000 and 1/5,000 aerial photographs are being taken for 1/5,000 topographic map correction and 1/1,000 topographic map production.

However, since aerial photographic image information is photographed from an aircraft, optical deformation is inevitably generated for distant points. As a result, in the process of drawing the obtained aerial photographic image, a slight error occurs when the aerial photographic image is matched to the GPS coordinates of a certain grid shape.

Therefore, there is a problem in that the reliability of the digital map is lowered because the shape and size of artificial structures or various topographical features, etc., which are shown by drawing processing the aerial photographic image, are slightly different from the actual ones.

In addition, since topographical maps at the level of 1/1,000 are being produced in recent years, the precision required for aerial images used as basic data for topographical map production is also increasing.

It is a device that measures distances to and transmits the measured GPS coordinates and measured distance data to the outside through wireless communication. In addition, the measuring device 100 may additionally capture surrounding geographic features.

The present invention randomly selects a plurality of calibration reference points among the geographical features of the area where aerial photography is performed, actually measures the GPS coordinates of each calibration reference point and the distance from the corresponding GPS coordinates to the surrounding feature, and obtains the GPS coordinates and distance data. Based on this, it is characterized in that the correction is performed on the aerial photographed image, which may have distortion due to the optical limit. The measuring device 100 is based on the GPS coordinates and the corresponding GPS It enables to collect distance data from coordinates to surrounding cast features and image information of surrounding features.

The measurement information storage module 200 is a module for receiving and storing the GPS coordinates and measured distance data of each calibration reference point transmitted by the measurement device 100, and specifically, a computer device equipped with a wireless communication means and a memory means. is implemented as

In addition, the aerial photographing image DB 210 is a means for storing aerial photographic images generated as a result of aerial photographing.

Since recent aerial photography is being done in a digital manner, if the server can perform real-time communication with an aircraft performing aerial photography, it is also possible to construct a DB by receiving transmission simultaneously with filming. In this case, the aerial image DB 210 will be implemented in a memory unit of a computer device that communicates with an aircraft performing aerial photography in real time.

In addition, the primary drawing processing module 400 synthesizes the GPS coordinates and distance data stored in the measurement information storage module 200 with the aerial photographing image data stored in the aerial photographic image DB 210 to obtain a primary drawing image. It is a module that is implemented in the computer to create. That is, it is implemented by a computer equipped with a processor and S/W that performs image synthesis.

The primary drawing processing module 400 generates a primary drawing image by synthesizing or reflecting the GPS coordinates and measured distance data measured by the measurement device 100 to the calibration reference point indicated in the aerial photographic image DB 210. .

It is a module implemented in a computer to generate a final drawing image by partially enlarging or reducing the primary drawing image using a known digital image processing technology so that the location of the map and the location of the surrounding feature match each other on a scale.

2 is a view showing the overall appearance of a measuring device according to an embodiment of the present invention.

As shown, the measuring device 10 includes a support plate 110, a leg member 120, a GPS receiver 130, a support pipe 140, a support 150, a driving unit 160, and a mounting member 170. ), a laser distance meter 180, a transmission unit 190, an elastic support unit 700, a rotation unit 600, a rotation control unit 300, a height adjustment unit 400, and a camera unit 800. .

At this time, the support plate 110 is formed of a triangular flat plate member, and a leg member 120 whose length can be adjusted is coupled to each corner of the lower end of the support plate 110, and the leg members 120 are each independently lengthwise. Since it is adjustable, even if the place where the measuring device 100 is installed is not flat, the support plate 110 can be installed while maintaining a level.

In addition, the support pipe 140 is a tubular member provided through the central portion of the support plate 110, and has a bolt member 141 coupled through the side surface thereof, and is a portion into which the support 150 is inserted. .

At this time, the support 150 is inserted into the support pipe 140 in a state in which the bolt member 141 is loosened, and when an appropriate height is set, the support member 150 is configured to be fixed in position by tightening the bolt member 141.

Therefore, when an obstacle obstructing the distance measurement of the laser distance meter 180 is within a certain height, the height of the support 150 may be raised and then fixed.

In addition, the driving unit 160 is a hexahedron-shaped module coupled to the upper end of the support 150, and has a power supply unit, a control circuit unit, and a rotation motor therein, and sends a control signal for the rotation motor to the control circuit unit. The main control unit 161 is provided on the outer side, and the pivoting shaft 162 for supplying a rotational driving force to the outside to allow rotation at a predetermined angle unit protrudes vertically upward.

Therefore, the driving unit 160 enables the laser distance meter 180 to measure the distance to the surrounding feature while rotating at a predetermined angle from the calibration reference point.

Specifically, since the mounting member 170, which is a disk-shaped member, is coupled to the upper end of the driving unit 160, a rotational shaft joint coupled to the rotational axis 162 of the driving unit 160 is centered at the lower end of the mounting member 170. By equipping the part 171, it can be fixed to each other.

In addition, the laser distance meter 180 is coupled to the center of the upper surface of the mounting member 170 and measures the time for the laser beam emitted from the laser L to reach the target TG (see FIG. 6) to measure the distance of the laser beam. Since the speed is known, the distance value can be calculated from the relationship between time, speed and distance.

Here, the important point is that in the case of distance measurement, it is common to measure the time taken by detecting the returning laser beam after shooting the laser beam and calculate the distance value based on this, but in some cases, the reflected laser beam There are many cases in which distance measurement failure occurs because it is not accurately reflected or cannot be detected frequently, so the present invention does not employ such a method, and discloses the present invention's own target (TG) aiming and detection type distance measurement method.

In addition, the GPS receiver 130 is provided on one of the edges of the support plate 110 and is a means for locating GPS coordinates, and is a conventional method for locating corresponding coordinate values by analyzing signals received in real time from GPS satellites. It can be implemented as a GPS measuring device.

In addition, the transmission unit 190 is provided on one of the rims of the support plate 110 and is connected to the GPS receiver 130 and the laser range finder 180 in a circuit, so that the GPS receiver 130 determines positioning. A device that stores GPS coordinates and the distance data measured by the laser distance meter 180 and transmits them to a designated external counterpart through wireless communication of a public communication method or a private communication method. A memory semiconductor and a signal processing circuit, Equipped with a wireless communication circuit and an antenna.

Thus, the measurement information storage module 200 receives and stores the distance data measured between the GPS coordinates transmitted by the transmission unit 190 and the surrounding landmarks in real time.

Details of the elastic support unit 700, the rotation unit 600, the rotation control unit 300, the height adjustment unit 400, and the camera unit 800 will be described below.

3 is a diagram showing a state of measuring a distance using a laser distance meter according to an embodiment of the present invention as an example, and FIG. 4 is a drawing correction module according to an embodiment of the present invention for a primary drawing image. It is a drawing showing the state of performing correction as an example.

As shown, the laser range finder 180 coupled on the mounting member 170 measures the distance to the feature (target) in the northeast direction represented by a triangle (①), and rotates a certain angle in the northeast direction. After (②), by going through the process of measuring the distance to the feature expressed as a trapezoid (③), the distance data can be generated by measuring the distance from the calibration reference point where the measuring device 100 is installed to the surrounding feature. do.

These surrounding features may be scanned by the laser distance meter 180 on their own to measure the distance value or measure the distance value with the specified feature by remote control, and may also be processed by a built-in program, , the operator may operate it manually.

The drawing shown at the top of FIG. 4 is a primary drawing image. Looking at the primary drawing image, a place represented by a black dot is a calibration reference point, and features expressed as triangles and trapezoids appear around the calibration reference point.

However, assuming that the distance from the calibration reference point to the triangle corresponds to the actual distance data when viewed in terms of scale, but the distance from the calibration reference point to the trapezoid is smaller than the actual distance data when viewed in terms of scale, the drawing correction module (230 ) is to generate a final drawing image by performing correction to correspond to actual distance data by partially reducing the image of the circle indicated by the dotted line as shown at the bottom of FIG.

5 is a block diagram showing each configuration of a laser distance meter according to an embodiment of the present invention.

The laser distance meter 180 includes a laser control unit 181 which is a CPU.

Also, a wireless communication unit 182 is connected to the laser control unit 181, and the wireless communication unit 182 is configured to exchange wireless communication signals with the target TG through the communication antenna ANT.

In addition, a time control unit 183 is further connected to the laser control unit 181, and the time control unit 183 generates a clock synchronization signal and manages the current time.

In addition, a memory unit 184 is connected to the laser control unit 181 to store, update, and delete time information among received information.

In addition, a distance calculation unit 185 is connected to the laser control unit 181, and the distance calculation unit 185 is a calculator used to calculate the distance to the target TG using the speed and arrival time information of the laser beam.

In addition, a target confirmation unit 186 may be further connected to the laser control unit 181, and the target confirmation unit 186 automatically controls the target TG through a program or remote control rather than manual operation. It is a means for recognizing whether or not it is adjusted through a signal sent from the control board (CTB) and outputting to the laser control unit 181 whether or not the zero point is adjusted. Alternatively, when the lamp (LAM) is turned on, the light may be sensed to check whether the zero point is adjusted.

In this configuration, the distance measurement method is as follows.

First, in a state in which a laser beam is oscillated through a laser (L), it is aimed toward a target (TG).

Then, when the laser beam moves and is irradiated to the target hole TH of the target TG, the photodiode DIO operates and current flows, and the lamp LAM lights up under the control of the control board CTB.

When the lamp LAM is turned on, since it is aimed at the target TG, the laser controller 181 turns off the laser beam and transmits a clock synchronization signal through the time controller 183.

Accordingly, the target TG or the neighboring targets TG that have received the clock synchronization signal are synchronized with the clock transmitted by the time control unit 183 and maintain the same time.

In this way, when the clocks are synchronized, the laser control unit 181 then oscillates the laser beam again and simultaneously stores the laser beam oscillation time in the memory unit 184 through the time control unit 183.

Meanwhile, the target TG receives the laser beam, stores the current time at that moment, transmits the stored time to the wireless communication unit 182, and the received time of the target is stored in the memory unit 184.

Thereafter, the distance calculation unit 185 checks the two time differences (the laser beam oscillation time and the time when the target receives the laser beam) stored in the memory unit 184, and calculates the distance value to the target TG by calculating it. will do

Through this process, the distance value can be accurately calculated.

Here, the control board (CTB) is a PCB board equipped with an MCU (Main Control Unit), and is a controller with a clock synchronization function capable of setting a time, and detects when a laser beam is received through a photodiode (DIO). It is configured to confirm that the light has been accurately received, and to transmit the time information to the laser distance meter 180 by storing the time (time) at the time of receiving the light at the same time as receiving the light. Therefore, when a specific signal, for example, a clock synchronization signal is received from the laser distance meter 180, the clock, that is, the time is synchronized according to the signal.

To this end, a wireless communication module (WTR) capable of transmitting and receiving wireless signals is further installed on one side of the target plate (TP) and is configured to transmit and receive control signals by being connected to the control board (CTB).

In addition, a storage battery (EBT) is embedded in the target plate (TP), and the storage battery (EBT) stores electricity obtained by condensing light from a solar panel (STP) inclined at an upper end of the target plate (TP). It is used as the power required for control and operation.

In particular, a lamp (LAM) is installed on the upper side of the front of the target plate (TP) and controlled to turn on when the laser beam is received by the photodiode (DIO), so that the operator can ensure that the laser beam accurately reaches the target (TG) from a distance. It is configured so that it can be easily checked, and it also becomes a kind of zero-point adjustment signal.

In addition, for stable installation of the target pillar PO, as shown in the example of FIG. 7, a screw thread SCW of a certain length is formed in the target pillar PO, and the screw thread SCW has a cylindrical shape with a downward opening. A support cup (CUP) may be screwed.

In this case, when the support cup (CUP) is rotated and tightened to dig into the ground in a state in which the target pillar (PO) is driven into the ground and erected, the target pillar (PO) maintains a stable standing state without shaking.
