Description

Field of the Invention The present invention relates to a digital map production system that updates and updates existing and updated geographic information,

The present invention relates to a digital map production system for comparing and updating existing and updated geographical information in the field of digital map technology. More specifically, the present invention can stably perform a role of a reference point to accurately detect an error of coordinate data of a digital map In particular, by comparing the GPS position information of the aircraft in the photographing area in the aerial photographing and the actual position coordinates of the photographing area, a region requiring re-photographing is set, and a digital map is produced based on the comparison. The present invention relates to a digital map production system for comparing and updating updated and updated geographical information that minimizes the inaccuracy of a digital map caused by a change of a geographical location by comparing updated geographical information.

A digital map is a digital map that is obtained by analyzing various numerical information obtained by surveying maps, aerial photographs, and satellite images, and numerically editing the numerical information.

Therefore, the digital map must be accurately applied to the displayed topographical image so that the user can easily obtain the geographical / geographical information while viewing the map, and the drawn topographical image should be accurately applied to the geographical information It should be precisely shown, mainly used for various cadastral maps and topographical maps.

These digital maps are produced from the images collected through aerial photographing and ground photographing, and the collected images are completed with a complete image through a mutual connection between neighboring images, and are produced as a digital map.

However, in order to interconnect the collected images, a reference for accurate connection between images is required. In order to accurately capture the reference, it is necessary to take an accurate aerial image image and a ground image image according to the GPS coordinates.

That is, the aerial photographing and the ground photographing are accurately performed according to the GPS coordinates, and the accurate aerial image image and the ground image image are collected according to the GPS coordinates.

For this purpose, a reference point serving as a reference of photographing is required, and a device capable of externally displaying the reference point is also required.

Conventionally, various apparatuses have been proposed in which a camera receives a signal or light so that the position of the corresponding point can be recognized.

Conventionally, most of the conventional devices have a technology for allowing the camera to accurately receive and photograph light irradiated by itself, and in particular, there is no function of protecting itself from external pollution and managing itself, and thus the life of the device is short .

Of course, such a problem prevents the reference point performed by the apparatus from fully exercising, and thus it has been an urgent problem to be solved.

In addition, in order to improve the inaccuracy of the digital map due to the terrain change, it is necessary to re-photograph the periodically changed terrain to acquire the update information and to update it by comparing with the existing information. In this case, It can not be built.

The outer surface of the fixed post 1120, the flow post 1130, the rotating post 1140 and the camera fixing box 1150 is coated with a coating layer for improving transparency, moisture-proofing, antifouling, scratch resistance and crack resistance .

The coating layer is formed by spray coating a coating solution. The coating solution is prepared by mixing 4.5 wt% of polyacrylamide, 2.5 wt% of behenic acid, 2.5 wt% of dioctyl azide (DOA), 2.5 wt% of sodium percarbonate, 1.5 wt% of epichlorohydrin, 1.5 wt% of ethylenediaminetetraacetic acid, 1.5 wt% of glycerol monostearate, 2.5 wt% of transparent alumina, 2.5 wt% of colloidal silica, sodium sesquicarbonate (Na ₂ CO ₃ % NaHCO ₃ .2H ₂ O), 1.5% by weight of Pozzolan, 2% by weight of alkylene amide, 2% by weight of triglyceride, and the rest of the polycarbonate resin.

In this case, the polyacrylamide is added to increase the adhesive force of the coating film and the bonding force between the inorganic materials, and behenic acid is added to improve the moldability by increasing the lubricity of the resin, and the dioctyl azide (DOA) Sodium percarbonate is added for antimicrobial activity, epichlorohydrin is added as a colorless liquid for stabilization of the surface protective layer, and ethylenediaminetetraacetic acid is oxidized And Glycerol Mono stearate is added to increase the activity at the interface to increase the flatness of the coating film and transparent alumina is added to enhance the scratch resistance by increasing the surface hardness, The colloidal silica is preferably an amorphous silica sol having a particle size of 5-50 nm Sodium sodium sesquisulfonate (Na ₂ CO ₃ .NaHCO ₃ .H ₂ O) is added as a natural alkali agent to enhance the antifouling property. The polycarbonate resin has transparency and durability, It is added for adhesion enhancement.

Particularly, 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 acid resistance, corrosion resistance, durability and waterproof property, Is preferably 0.1 to 0.2 mm.

Also, the alkylene amide is added to maintain lubricity and stability, and is added so as to smooth the mixing and prevent the occurrence of crumbling after mixing. Triglyceride is a coating agent mainly composed of ricinoleic acid. It is added to increase the surface smoothness of each of the outer and inner surfaces, thereby enhancing the antifouling property and increasing the erosion resistance.

In addition, as shown in FIG. 10, the present invention may further include a sound wave generator 2000 for emitting a sound wave to the upper surface of the vehicle CAR so that the bird can be easily driven out when a bird or the like exists in the front of the photograph.

The sound wave generator 2000 amplifies a sound wave and oscillates strongly forward through a horn 2100 so that a bird can be surprised by a sound wave impact.

This can fully affect a bird.

It is particularly preferable that the inside of the horn 332 is arranged to be enlarged toward the front side so that the sound waves are expanded and waved.
