It is possible to acquire distance data through the laser range finder 170 of the instrument 100 while minimizing disturbance of foreign matter even in the event of a rainstorm.

The target 700 having the above characteristics was prepared by adding 1.0% by weight of Pozzolan, 3.0% by weight of monoglyceride, Expandable Graphite 8.0 (by weight) to the inner and outer surfaces of the target 700 so as to have heat resistance, chemical resistance and chemical resistance. , 2.0% by weight of mullite, 2.0% by weight of ethylene glycol monomethyl ether, 2.0% by weight of triglycerides, 2.0% by weight of sodium silicate, 1.5% by weight of terbium, It is preferable that a coating solution composed of 1.5 wt% of thiocyanic copper, 2.5 wt% of methylhydroxyethylcellulose (MEHEC), 2.5 wt% of alkylene amide and remaining epoxy resin is sprayed.

The pozzolan is mainly used as a concrete admixture, but it is an artificial pozzolan. In the present invention, natural pozzolans collected from weathered volcanic rocks and volcanic rocks are used to increase the acid resistance, corrosion resistance, durability and waterproof property. Mm is preferable.

The monoglyceride is added in order to enhance the antifouling property by promoting emulsification and inhibiting foreign matter from adhering to the surface.

Since the expanded graphite has a layered structure of graphite, when particles and small molecules are inserted between the layers, heat is applied to expand the particles several hundred times while being separated like an accordion, thereby enhancing the flame retardancy and flame resistance.

The mullite is resistant to high temperature and is added so as to be able to withstand even when outdoors in summer.

The above-mentioned ethylene glycol monomethyl ether is added for enhancing the durability by enhancing the adhesive property by maximizing the adhesion, and the triglyceride is a coating agent mainly composed of ricinoleic acid. In particular, the surface smoothness of the outer surface and the inner surface is increased, Is added to increase the erosion resistance, and sodium silicate is added to increase the surface adhesion.

Meanwhile, the laser range finder 170 of the present invention includes a laser controller 173 which functions as a CPU.

A laser communication unit 174 is connected to the laser control unit 173 to transmit and receive a radio signal to and from the target 700.

The laser control unit 173 is further connected to a laser vision control unit 175. The laser vision control unit generates a synchronization signal (or a clock synchronization signal) and manages current time information.

The laser controller 173 is connected to the laser memory 176 to store, update, and delete time information among the received information.

In addition, a laser distance calculator 177 is connected to the laser controller 173, and the laser distance calculator calculates the distance to the target 700 using the laser beam speed and arrival time information.

In a state in which the laser range finder 170 is configured as described above, a method of measuring the distance is as follows.

First, the laser beam is output through the laser distance meter 170 and aimed at the target 700.

When the target beam 722 of the target 700 is irradiated with the laser beam while the laser beam is moving, the target photodiode 722 is operated to flow a current so that the target lamp 724 is lit under the control of the target control board 725 It comes.

When the target lamp 724 is turned on, the laser control unit 173 turns off the laser beam and transmits the synchronization signal through the laser vision control unit 175 because the target lamp 700 is in the state of being aligned.

Accordingly, all of the one or more targets 700 that have received the synchronization signal are synchronized with the time information transmitted by the laser time control unit 175 to maintain the same time.

When the time is synchronized, the subsequent laser control unit 173 causes the laser beam to oscillate again, and at the same time, stores the laser beam oscillation time in the laser memory unit 176 through the laser time control unit 175.

On the other hand, the target 700 receives the laser beam, stores the time instant, transmits the time information stored in the laser communication unit 174, and the time information of the received target is stored in the laser memory unit 176 .

Thereafter, the laser distance arithmetic unit 177 confirms the two time differences (the laser beam oscillation time and the time when the target receives the laser beam) stored in the laser memory unit 176 and calculates the distance to the target 700 Data is calculated.

Through the above process, it is possible to accurately calculate the distance data to the desired feature item.

The measurement data storage 200 receives and stores GPS coordinate data and measured distance data of each correction reference point transmitted by the instrument 100. Specifically, .

The aviation image DB 300 is a means for storing image data generated as a result of aviation photographing. Since recent aviation photographing is performed in a digital manner, the server performs communication in real time with an airplane It is possible to construct a DB by receiving image data at the same time as shooting. In this case, the aviation image DB will be implemented in a memory unit of a computer device that performs real-time communication with an airplane that performs aerial photographing.

That is, it is implemented as a computer equipped with a processor for performing image synthesis and an S / W.

In addition, the rendering processor 400 synthesizes or reflects the GPS coordinate data and measured distance data positioned by the measuring instrument 100 at the correction reference point indicated in the aviation image DB 300, thereby generating a picture image.

The picture image corrector 500 corrects the picture image generated by the picture processor 400 and compares the position of the correction reference points displayed on the picture image with the distance data and the GPS coordinate data synthesized in the picture image, Is a module implemented in a computer to generate a final rendered image by partially enlarging or reducing the rendered image using known digital image processing techniques so that the position of the feature appears scaled up coincidentally.

Assuming that the distance from the correction reference point to the circle corresponds to the actual distance data in view of the scale, but the distance from the correction reference point to the triangle is smaller or larger than the actual distance data in view of the accumulation, The corrector 500 performs correction so as to correspond to the actual distance data by partially reducing or enlarging the triangle image of the original circle indicated by the dotted line as shown in the right side of FIG. 8 to generate a final view image.

The illustrated image DB 600 is configured to store a final rendered image generated by the illustrated image corrector 500 and is implemented as a typical server computer.

As a result, the present invention is installed at two or more correction reference points arbitrarily selected from among the features of the area in which the aerial photographing is performed, measures the GPS coordinates of each correction reference point, measures the distance to the surrounding features, Synthesized and generated by using the image, it is advantageous to precisely map the symmetric feature.
