The drawing image is a map of the topographic map of the ground using an image of the ground taken from an aircraft. It is a map that reflects coordinate information, position information, and numerical information (hereinafter referred to as "coordinate information" Is a numerical map, and a numerical map is generally produced by a modification drawing method, an analysis drawing method, and a numerical drawing method.

All of the terrestrial features on the ground may be partially changed by large-scale construction, etc., and the numerical value of the area where the change occurred should be updated or updated at any time in the numerical map in which the image of the figure is digitized.

Since aerial photographs are taken using aircrafts that require high maintenance costs and all the images taken are required to be individually inspected by national agencies such as the National Intelligence Service, it is very cumbersome and time consuming in terms of cost and procedural aspects It is common.

In addition, the terrain of the ground is changed by construction, development, construction, and so on, and it can be very burdensome to repeat the expensive aerial photograph every time.

On the other hand, due to the optical limitations such as the curvature (distortion factor, distortion rate) and the angle of camera lens, it is difficult to shoot the image in a perfect plane even in the case of using the aircraft, It is common to have a curvature.

A plurality of photographed images or partial images having a partially distorted image are synthesized and edited into a single integrated image, which requires partial modification and update.

There is a system and a method of digital map making using a digital map and a digital map by a patent registration No. 10-0558367 (registered on Mar. 28, 2006), which is a conventional technology for producing a digital map from an aerial photographed image.

In this case, the control unit 1120 controls the horizontal adjustment motor unit of the plurality of horizontal adjustment motor units 1180 to rotate in a clockwise direction in a plan view according to the detection signal of the horizontal detection sensor 1270, The horizontal adjustment motor portion is raised by the screw action of the male screw portion 1191 of the horizontal adjustment screw 1190 engaged with the female screw portion 1182 of the upper horizontal adjustment motor 1181, So that the horizontal adjustment screw 1190 is lowered by the screw action of the male screw portion 1191 of the horizontal adjustment screw 1190 engaged with the female screw portion 1182 of the motor shaft 1181 do.

Here, it is assumed that the communication network 3000 is the same as a mobile communication system (hereinafter, referred to as a " communication network ") and includes a wired communication network and the Internet. A mobile communication system is generally known and will not be described in detail.

The communication network 3000 should confirm the position of the mobile communication unit 1260 or the mobile terminal (hereinafter, referred to as "mobile communication unit") based on its operating characteristic, with the base station (BS) as its center.

The base station is a direct connection of the mobile communication unit 1260 by radio, forming a certain service area, and a plurality of base stations are continuously installed at regular intervals to form a nationwide service area.

The communication network 3000 must calculate the direction of movement of the mobile communication unit 1260 and handover the base station located in the direction of moving based on the currently connected base station to allocate a channel to be connected to the mobile communication unit 1260, It is necessary to specify the time point at which the handover is calculated by calculating the moving speed.

The communication network 3000 should always check the location information of the mobile communication unit 1260 in the moving state according to the operational characteristics.

At this time, the communication network 3000 confirms the position of the mobile communication unit 1260 around the position of the base station, and the coordinate information of the base station is already known accurately.

When three base stations around the mobile communication unit 1260 calculate the straight line distance to the mobile communication unit 1260, the position of the mobile communication unit 1260 can be accurately measured by the triangulation method.

The service for confirming and providing the coordinate information on the position of the mobile communication unit 1260 around the base station already knowing the coordinate information is called an LBS (Location Based Service) service.

The LBS processing unit 1240 requests the LBS service to the communication network 3000 connected to the mobile communication unit 1260 and provides the location information of the mobile communication unit by the LBS service provided by the communication network, And also applies the same to the control unit 1220 as the second coordinate information.

A plurality of programs, operation parameters, operation data, and the like are recorded in the buffer unit 1250 and can be retrieved by the corresponding control signals of the control unit 1220.

The coordinate values obtained by arithmetic mean calculation by the control unit 1220 are referred to as average coordinate values.

The control unit 1220 encrypts the average coordinate value arithmetically averaged in the specified data format.

The data format can be classified into an overhead area, a field area in which average coordinate values are recorded, a check area to search for errors, a time area in which time information is recorded, and the like. Can also be encrypted.

(Decryption) can not be performed unless the order in which the respective regions of the data format are arranged, the size of the data that can be allocated and recorded, and the data size of the entire frame are known.

On the other hand, there is an advantage that there is no possibility of an error because it is encrypted and transmitted.

Also, there is an advantage in that the accuracy is increased to three times or more since arithmetic mean calculation is performed on the values obtained by constituting each of the first to third pieces of the GPS receiver 840.

Further, the laser-receiving portions 840 are installed on the disc portion 1130 at equal intervals (uniform intervals) of 120 degrees, and the left and right rotations of the disc portion 1130 are repeated by any one of the elapsed time and moving distance It is possible to eliminate the error caused by the reception antenna installation position of the GPS receiver 840 and to receive the GPS signals received from the respective reception antennas under the same condition.

The Global Positioning System (GPS) 2000 is composed of 24 GPS satellites operating at an altitude of 20 to 25 km (Km) above ground, preferably at an average altitude of about 20,183 km, Is a global positioning system that broadcasts free-of-charge GPS signals that can be analyzed by sea level, longitude, latitude and time. On the other hand, the GPS signal processor 1230 must receive the GPS signal from at least three GPS satellites 2000 to analyze position information.

The communication network 3000 is a general structure including all types of communication networks such as a mobile communication network, a wireless communication network, a wired communication network, a data communication network, and the Internet.

Based on the applied part, The coordinate value data of the entire digital map can be updated.

The control unit unit constituting the coordinate processing unit searches the buffer unit and loads operation parameters, data, etc., Set the activation state.

The control unit analyzes the loaded information (data, parameters) and judges whether it is set to control based on elapsed time or to control based on the moved distance.

If it is determined that the control unit unit is set to control based on the elapsed time, the elapsed time information after the field measurement unit starts to be operated in the field is continuously analyzed in real time.

The control unit may change the driving direction of the step motor unit from forward rotation to reverse rotation in a predetermined unit of time specified by the information loaded by the analyzed elapsed time information in real time, And outputs the corresponding control signal.

On the other hand, if it is determined that the control unit unit is set to control based on the distance traveled, the moving distance information after the field measurement unit starts to be operated in the field is continuously analyzed in real time.

The control unit unit controls the driving direction of the step motor unit in the forward direction rotation direction to the reverse direction rotation direction in units of a predetermined set distance designated by the information loaded by the moving distance information analyzed in real time, And outputs the corresponding control signal for controlling the switching.

The control unit unit controls the geofust treatment unit to output corresponding control signals for real-time analysis of the geofos information received by the first to third geoface-receiving units in accordance with the moving direction, moving speed, latitude, longitude and altitude.

The control unit outputs a corresponding control signal for arithmetically averaging and outputting the analyzed information in real time.

The control unit outputs a corresponding control signal for real-time calculation of the arithmetic mean value to be transmitted to the drawing update server or the specified counterpart in real time by mobile communication.

The apparatus operated in this way has an advantage that no error is caused by the installation position of the GPS reception antenna.

In addition, the arithmetic average of the analysis values of the received pieces of information of the pieces of paper-side information received by each of the three laser module modules is improved, so that the first coordinate information finally output is improved to an accuracy of three times or more, and the first coordinate information and the second coordinate information The accuracy is improved to 6 times or more as a whole.

In addition, since the numerical information updating system for immediately correcting the error numerical information according to the present embodiment includes the horizontal adjusting means, the first through third laser power sources 810, 820 and 830 are always kept at the same height.

That is, when the ground surface is inclined forward or backward or tilted left and right in the process of moving the vehicle on which the vehicle body side portion 1000 is mounted, the first to third dust- The height of the first to third SAW antennae 810, 820 and 830 are different from each other. At this time, the mounting plate 1111 mounted on the mounting plate 1111 is tilted, The sensor 1190 senses the level of the mounting plate 1111 and outputs a sensing signal and the control unit 1220 drives the plurality of horizontal adjustment motor units 1180 according to the sensing signal of the horizontal sensing sensor 1190. [ The motor shaft 1181 of the horizontal adjustment motor unit in the lower position of the motor shaft 1181 is controlled to rotate clockwise when viewed from the plane so that the number of the horizontal adjustment screws 1190 engaged with the female screw unit 1182 of the motor shaft 1181 By the screwing action of the threaded portion 1191, The upper horizontal adjustment motor unit is controlled to rotate in a counterclockwise direction in a plan view so that the horizontal adjustment motor unit can be rotated in a horizontal direction The horizontal adjusting screw 1190 is lowered and separated from the upper side of the mounting plate 1111 by the screw action of the male screw portion 1191 of the screw 1190.
