Description

Technical Field

[0001] The present invention relates to the technical field of topographic mapping, and in particular to a method and system for mapping orogenic belts based on digital maps. Background Art

[0002] An orogenic belt is a narrow and intense tectonic deformation zone in the upper part of the earth caused by the violent tectonic changes of the lithosphere and the reorganization of its materials and structures, which causes the crust to squeeze and contract, often forming linear relatively uplifted mountains on the surface. It is generally synonymous or nearly synonymous with fold belts and tectonic activity belts. It includes mountains formed by crustal compression and contraction, rock folding and fracture, accompanied by magmatic activity and metamorphism, as well as tensile structures and shear slips that form rifts and rift basins while causing relative uplift of the surrounding areas, forming mountain systems. This kind of lateral contraction, vertical thickening, and uplift to form mountains to form tectonic mountains is called orogeny or orogenic movement, which is comparable to the continental movement in crustal movement.

[0003] Orogenic belt mapping is the basic work of geological exploration in orogenic belts. Its purpose is to systematically collect and record ground geological observations of natural outcrops of bedrock and engineering geological points, comprehensively study the stratigraphic sequence, rock structure characteristics and surface geological laws, compile relevant geological maps reflecting the geological characteristics and laws of orogenic belts, and provide basic ground geological data for the corresponding stage of geological exploration in orogenic belts. The existing coal geological mapping sequence is: collect regional topographic maps → indoor data collection → field exploration → measured profiles, trenching construction recording → mapping → report preparation.

[0004] In the past, we selected topographic maps of corresponding scales according to different exploration stages, compared topographic maps with the actual natural landforms in the field, determined geological points on the map, described geological phenomena in special paper notebooks, and drew sketches manually.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figure 1 As shown, the present invention provides a method for mapping an orogenic belt based on a digital map, comprising the following steps:

[0043] Step S1, using a digital map to obtain element data of the orogenic belt, and registering the orogenic belt to fill in a base map template according to the element data;

[0044] In step S1, the specific method of filling in the base map template according to the element data of the orogenic belt includes:

[0045] Step S101, compressing the element data at equal scale to obtain second element data, and calibrating the first three-dimensional coordinates of the orogenic belt according to the second element data;

[0046] Step S102: Draw a curve along the first three-dimensional coordinate boundary to obtain a base map template of the orogenic belt.

[0047] Among them, the element data includes but is not limited to the three-dimensional coordinates of the orogenic belt, the range of rock layers, the range of plate land, the range of mountains, etc. The digital map is the digital existence of the paper map. It is a discrete data of ground elements and phenomena with certain coordinates and attributes in a certain coordinate system. It is a summarized and ordered collection on a computer-recognizable storage medium. It has the function of digital map to output drawings of any scale and any range. It is easy to modify and can greatly shorten the mapping time; it can be easily combined with other information sources such as satellite images and aerial photos to generate new types of maps. Therefore, using digital maps to map the orogenic belt can easily obtain the element data of the orogenic belt terrain, and can compress it and combine it with image data, which is simple and efficient.

[0048] Step S2, using remote sensing technology to obtain image data of the orogenic belt, and drawing unit outlines on the base map template according to the image data;

[0049] In the step S2, the specific method of drawing the unit outline on the base map template according to the image data includes:

[0050] Step S201, compressing the image data according to the equal scale in step S101 to obtain second image data, and calibrating the second three-dimensional coordinates of the orogenic belt on the base map template with the second image data;

[0051] Step S202: Draw a curve along the second three-dimensional coordinate boundary to obtain a unit outline of the orogenic belt.

[0052] Among them, remote sensing technology is a technology that detects and identifies targets by sensing electromagnetic waves, visible light, and infrared rays reflected or radiated by targets from a long distance. Modern remote sensing technology mainly includes information acquisition, transmission, storage, and processing. The complete system that completes the above functions is called a remote sensing system. Its core component is the remote sensor that obtains information. There are many types of remote sensors, mainly cameras, video cameras, multispectral scanners, imaging spectrometers, etc. Transmission equipment is used to transmit remote sensing information from a long-distance platform (such as a satellite) back to the ground station. Information processing equipment includes color synthesizers, image readers, and digital image processors.

[0053] Specifically, remote sensors are used to obtain image data such as topographic structural imaging maps of the orogenic belt, and the image data are compressed to the base map template at the same scale. The unit contours of each topographic unit in the base map template are further calibrated to obtain more accurate and realistic unit contours of the orogenic belt.

[0054] Step S3: using the two-dimensional code marking technology to color and mark all the unit contours in turn to obtain an orogenic belt map.

[0055] In step S3, the specific method of obtaining the orogenic belt mapping by using the two-dimensional code marking technology includes:

[0056] Step S301, selecting mutually exclusive first grayscale color blocks inside each unit outline to form a color block two-dimensional code, and filling the color block two-dimensional code into each unit outline;

[0057] In the step S301, the color block two-dimensional code includes an editable edge area and an operation center area, the operation center area is used to enter the editing operation platform, and the editable edge area is assigned element data through the editing operation platform.

[0058] The operation center area and the editable edge area are respectively provided with an editing mark for entering the editing operation platform and an identification mark for identifying the color block QR code marking information;

[0059] When the QR code recognition terminal scans the identification mark in the editable edge area, it will not enter the editing operation platform;

[0060] When the QR code recognition terminal only scans the editing mark in the operation center area, it enters the operation editing platform.

[0061] The color block monomer of the color block two-dimensional code is composed of a solid dot mark and a solid bar mark, and one end of the solid bar mark coincides with the solid dot mark; each of the color block monomers contains a kind of marking information, and any combination of two or more of the color block monomers represents a kind of marking information; the method for representing the marking information includes:

[0062] A plane coordinate system is established with the center of the operation center area as the coordinate origin, the solid dot mark of each color block monomer corresponds to a coordinate O, the end of the solid bar mark that does not overlap with the solid dot mark corresponds to a coordinate P, and the coordinates O and P of the same color block monomer constitute a labeling information; all the color block monomers in the color block QR code are composed of several permutations and combinations, and each permutation and combination forms an independent labeling information; entering the editing operation platform is by setting the labeling information represented by each permutation and combination.

[0063] Step S302, filling the drawn curves at the adjacent intersections of each unit outline with a second grayscale color that is mutually exclusive with all the first grayscale colors in step S301;

[0064] Step S303: The element data of each unit outline is integrated into the color block two-dimensional code to perform parameter annotation to obtain the orogenic belt and fill it into a map.

[0065] In step S303, the specific method of integrating the element data of each unit outline into the color block two-dimensional code is:

[0066] Enter the editing operation platform to arrange and combine the color block monomers according to the element data to generate a unique color block QR code for the unit outline.

[0067] Specifically, the QR code is divided into two areas through a specific color block QR code graphic design. One part is used to enter the editable system to edit the permutation and combination of the color block QR code to integrate the element data, and the other part is used to display the annotation information. The graphic utilizes the method of permutation and combination to form countless possibilities. Therefore, its annotation functionality is greatly increased, and the user can operate independently. It adopts both modular and freestyle editing methods. Even users who are not familiar with network information editing can use it easily. The intelligent QR code information is transmitted in a timely manner, and users can edit and adjust at any time. The beneficiaries can see the changes in the content instantly, and the element data is displayed indirectly, avoiding direct digital annotation on the filled-in map, causing a cluttered map and affecting the observation of the orogenic belt terrain.

[0068] Considering that in actual operation, there are many elements of the same category in the unit outline of each terrain. How to use QR code to plan them into the same category? The specific method is as follows:

[0069] The center of the operation center area of ​​the empty assigned QR code is taken as the standard point, the distance from the solid point mark of each monomer icon to the standard point is taken as the sub-information point A, and the angle between the line connecting the solid point mark to the standard point and the straight line where the solid bar mark is located is taken as the sub-information point B. The sub-information point A and the sub-information point B of the same monomer icon are combined to form a complete functional information. In this way, all the sub-information points A on the same arc centered on the standard point are the same category of information. At this time, there are two situations:

[0070] The first type is that the sub-information points B corresponding to the same sub-information points A on the same arc are different, and they are classified as the same category of information, indicating similar functions;

[0071] The second type is that the sub-information points B corresponding to the same sub-information point A on the same arc are different, but the positions are different. They are classified as equal information, indicating exactly the same functions.

[0072] like Figure 2 As shown, based on the above-mentioned orogenic belt mapping method based on digital maps, the present invention provides a system, comprising:

[0073] Data processing module, used to process element data, impact data, and draw base map templates and unit outlines;

[0074] Editing operation platform, used to edit the arrangement, combination and annotation information of color block QR codes;

[0075] The QR code recognition terminal is used to recognize the annotation information of the color block QR code to obtain the element data of the orogenic belt.

[0076] The editing operation platform also includes a password setting module, and a user can set a login password for entering the editing operation platform through the password setting module.

[0077] Set a login password to allow only designated users to edit information in the color block QR code. Others will not be able to display the corresponding content after scanning it, and cannot edit it. Illegal editing is rejected, ensuring the privacy and security of information transmission.

[0078] The present invention utilizes digital maps and remote sensing technology to map the orogenic belt, which can realize three-dimensional visual digital mapping, avoid the shortcomings of low efficiency and low precision caused by manual exploration and mapping, effectively show the overall topography of the orogenic belt, and utilize two-dimensional code annotation technology to annotate the element data of the orogenic belt topography, and can utilize the grayscale of color blocks to intuitively distinguish the various topographic units of the orogenic belt, and also hide the element data of each topographic unit, so as to avoid directly annotating on the mapping of the orogenic belt to interfere with the observation line of sight, so that the structural outline of the overall orogenic belt is neat and clear, and the terrain parameters can be obtained by identifying the color block two-dimensional code, which is convenient and fast.
