Numerical map manufacturing system for posting of reality building based on GNSS}

The present invention relates to a digital map production system. More specifically, the present invention relates to a digital map production system, and more specifically, to photograph ground objects in a desired area from a certain height and accumulate the images of the photographed ground objects to have a uniform size to generate a photorealistic image of the ground objects. , After the horizontal control of the ground object height information generation device is completed automatically or manually and precisely, the height information of the ground object is generated, and then the spatial information collected when creating the actual ground object image is used to obtain the height information on the digital map. This is about a digital map production system for posting actual ground objects.

In general, a Geographic Information System (GIS) refers to a computer-based system that uses and manages geographic data to solve space-related problems. When GIS was first developed in the early 1960s, it was nothing more than a computer-based program for processing map data. However, today, GIS has not only established itself as an important academic research field, but is also actively applied to all sectors of society by combining it with the latest information technology.

The basic characteristic of GIS is spatial, that is, it can handle attribute information related to the location of objects in geographical space. Maps are the most efficient way to represent the locations and properties of spatially distributed objects. Therefore, the most basic data in building GIS is a digital map. Unlike classic paper maps, digital maps can be said to be indexed by interpreting, numerically editing, and various topographical data obtained from survey maps, aerial photographs, and satellite images.

The process of building a numerical map is completed through several processes as follows. First, the paper map becomes a resin map through digitizing or scanning, and then goes through procedures to correct various input errors. Subsequently, through coordinate transformation, the coordinate system is converted to an actual coordinate system to suit the user's purpose, and then a topological structure is established to determine the mutual location and correlation between spatial objects. Afterwards, attribute data related to each geometrical data are entered into the numerical map whose topological structure has been established.

Recently, digital maps like the ones above have been combined with actual ground images, and in the case of digital maps with actual ground images, most of them have been produced by shooting from the ground, securing video data, and mapping photos to buildings. .

Previously, on digital maps that included actual ground objects, the actual ground objects were not posted with accurate heights, so users could check the ground objects only from a visual perspective, and digital maps were created using the height information of the ground objects. There was a difficulty in that it could not be reprocessed into the desired form. According to the Republic of Korea Patent No. 10-1220271 to solve this problem, the horizontality of the light wave generator could not be guaranteed, so the exact height of the actual ground object could not be measured and posted. there was.

Therefore, in a digital map production system that can post GNSS-based actual terrain features using height information of ground objects, there is a need for a system that can measure, collect, and reflect accurate height information of actual ground objects.

Prior art to solve this problem is disclosed in Korean Patent Publication No. 10-1905011 (2018.19.28.). However, this prior art only controls the level automatically and there is no technical means to control the level manually, so the range of options is limited, so improvement measures are required.

The technical configuration described above is background technology to aid understanding of the present invention, and does not mean that it is a conventional technology widely known in the technical field to which the present invention pertains.

Therefore, the technical task to be achieved by the present invention is to photograph ground objects in a desired area from a certain height, accumulate the images of the photographed ground objects to have a uniform size to generate a realistic ground object image, and provide a ground object height information generating device. After accurately completing the horizontal control automatically or manually, the height information of the ground object is generated, and then the spatial information collected when creating the image of the actual ground object is used to place the actual ground object with height information on the digital map. It provides a digital map production system that can post GNSS-based actual features using height information of objects.

Meanwhile, the ground object height information generating device 200 receives the same coordinate value as the GNSS coordinate value of the location where the aerially photographed ground object is located through the second GNSS receiver 210, and receives the first coordinate value of the light wave generator 220. 1 The light wave generator 221 and the second light wave generator 222 are controlled to radiate light waves to the ground object, and the ground object height information generator 230 receives the light wave reflected from the ground object and emits the light wave to the ground object. The angle and distance between the height information generating device 200 and the ground object are measured, the height of the ground object is calculated using the angle and distance information formed between the measured ground object, and the height of the ground object is calculated through the second GNSS receiver 210. It is combined with the received GNSS coordinate value and transmitted to the actual ground object generating device 300 through the ground object height information transmitter 240.

That is, the ground object height information generation unit 230 is installed at an appropriate distance from the object to be observed, inputs the machine height and target height, and then collimates a prism erected based on the building foundation floor to direct light waves toward the ground object in a horizontal direction. You can calculate the height of a building by measuring the horizontal distance by firing it and measuring the vertical angle by aiming the collimator at the top of the ground object.

In addition, the ground object height information generation unit 230 matches the surrounding information, including the status of construction around the ground object, the status of surrounding facilities, etc., to the height information of the ground object and transmits it according to the needs of the invention, thereby providing a device for generating actual ground objects in the future. In (300), digital map information with various information can be generated when producing or reproducing a digital map on which actual ground objects are posted.

As such, the present invention is not limited to the described embodiments, and it is obvious to those skilled in the art that various modifications and changes can be made without departing from the spirit and scope of the present invention. Accordingly, such modifications or variations should be considered to fall within the scope of the claims of the present invention.
