Description

Technical Field

[0001] This invention relates to the field of geological and mineral exploration, and in particular to a method and system for real-time plotting of field measured profiles. Background Technology

[0002] In field geological internships, measured profile mapping is an essential part of geological skills training for students. In the past, during the field measured profile mapping process, the data was recorded in the field logbook and on paper profile record calculation tables. It was not possible to draw the profile in real time using the measured data during the field measurement, and it was impossible to present the map visualization effect immediately. At the same time, it was also impossible to know whether the measurement data was correct.

[0003] After the field survey is completed, approximately two days are needed for indoor calculation and data processing to draw the profile and columnar sections. Continuous revisions are required throughout this process, making it a time-consuming and labor-intensive task for both students and teachers. This entire process is not only time-consuming and inefficient, but also fails to identify problems promptly. Therefore, there is an urgent need to utilize mobile data processing technology to transform the field survey workflow, enabling the measurement, recording, calculation, and drawing of field profiles. Figure 1 Integrated workflow.

[0004] Currently, numerous geological information researchers both domestically and internationally have made extensive attempts and innovations in the informatization of field geological data acquisition, achieving fruitful research results, which have been well promoted and applied in the actual collection of original geological and mineral information. In recent years, my country has also seen the emergence of many geological survey mapping systems, such as digital geological mapping systems, digital regional geological survey systems, the digital geological survey system of the Development and Research Center of the China Geological Survey, regional geological survey mapping practice auxiliary systems, and comprehensive geological information service platforms.

[0005] However, current machine-aided geological map compilation is all done on computers. Due to the bulky size and high price of computers, they are inconvenient for geologists to use when they are in the field. Mobile terminals have only achieved the digital acquisition of geological data in the field and have not yet achieved the function of real-time drawing of stratigraphic profile maps.

[0047] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0048] This invention provides a method for real-time plotting of field measured profiles, which is implemented through a real-time plotting system for field measured profiles;

[0049] refer to Figure 1 As the modular layout framework of the system, the real-time field measured profile drawing system includes: a route management module, a geographic location service module, and a visualization module;

[0050] refer to Figure 2The following is an example of the system's main interface. The specific operation of the real-time field profile drawing system is as follows: First, open the app to enter the main interface. Then, you can switch between the route management module and the geolocation service module via the menu. In the route management module, you can input, edit, and manage field observation routes and profile mapping routes. Both types of routes contain multiple observation points, so the system provides management functions for these observation points. Profile mapping routes also contain multiple traverses, which the system software can manage. After inputting the profile mapping route information and traverse information, the system's visualization module can perform real-time visualization drawing and rendering of the stratigraphic profile. In this function, you can add, delete, search, and modify information such as routes, observation points, profiles, and traverses. In the geolocation service module, location and point marking functions related to geolocation are available.

[0063] Specifically, each guide has 0 (without profile stratification points), 1 or more profile stratification points. The content collected at each profile stratification point may be lithology, structure, strata, or geological hazards (same as data collection along the field observation route). In addition, each profile stratification point also has information on slope distance and attitude.

[0073] Specifically, 1. Number the stratigraphic points of the profile: Starting from the starting point of the profile, number them sequentially according to the stratigraphic units, such as using the code ① to represent the first layer, and so on.

[0074] 2. Slope distance (l): The length of each layer on the conductor. The sum of the slope distances of each layer on the same conductor equals the total length of the conductor;

[0075] 3. Layered attitude: a. Dip (A): The straight line drawn perpendicular to the strike line and downward along the slope on the bedding plane is called the dip line. The direction of the dip line's projection onto the horizontal plane is the dip direction; b. Dip angle (α): The angle formed by the dip line and its projection onto the horizontal plane;

[0078] The calculation formula is:

[0079] γ=|AB|

[0080] In the formula: A – trend; B – azimuth of the conductor;

[0081] 2. Thickness (d)

[0082] This refers to the thickness of each layer "on each conductor". The calculation formula is:

[0084] In the formula: l – stratification distance; α – true dip angle of the stratum; β – ground slope angle along the traverse direction; γ – angle between the traverse direction and the dip direction of the rock strata. Use “+” when the rock strata dip is opposite to the topographic slope, and “-” otherwise.

[0087] 4. Segment thickness:

[0088] The sum of the thicknesses of all layers in the group;

[0089] 5. Cumulative Thickness:

[0090] Used for calculating workload and determining the scale of stratigraphic columnar diagrams;

[0091] 6. Angle (ε) between the overall direction and the azimuth of the traverse

[0092] The calculation formula is:

[0093] ε=BC

[0094] In the formula: B – azimuth of the traverse; C – overall direction of the profile;

[0095] 7. Slant Distance (L')

[0096] The projection length of each conductor onto the horizontal plane. The calculation formula is as follows:

[0097] L'=L·cosβ

[0098] Where: L – conductor length; β – slope angle;

[0099] 8. Horizontal Distance of Each Layer (l')

[0100] The projected length of each layer on the horizontal plane. The calculation formula is as follows:

[0101] l'=l·cosβ

[0102] Where: l – slope distance of each layer, β – slope angle;

[0103] 9. Line of sight distance (L”)

[0104] The length of the traverse oblique distance projected perpendicularly onto the direction of the total traverse. The calculation formula is as follows:

[0105] L″=L'·cosε

[0106] In the formula: L' – horizontal distance of the conductor, ε – angle between the total direction and the azimuth of the conductor;

[0107] 10. Layered viewing distance (l”)

[0108] The length of the oblique horizontal distance of each layer projected vertically onto the total direction of the section. The calculation formula is as follows:

[0109] l″=l'·cosε

[0110] In the formula: l' - horizontal distance between layers, ε - angle between the total direction and the azimuth of the conductor;

[0111] 11. Apparent slope angle (β')

[0112] The slope angle along the overall profile. The calculation formula is as follows:

[0113] β'=tanβ·cosε

[0114] In the formula: β - slope angle, ε - angle between the total direction and the azimuth of the traverse;

[0115] 12. Elevation difference (H)

[0116] This elevation difference is the apparent elevation difference, that is, the elevation difference seen from the main traverse line. The calculation formula is as follows:

[0129] S44: Draw a stratigraphic profile using the profile stratification point data and the additional attributes.

[0130] In this embodiment, the step of obtaining the attributes of the cross-sectional layer points in step S42 is as follows:

[0131] The attributes of the profile stratification points are the same as those of any one of the observation points in the field observation route, including lithological observation points, structural observation points, stratigraphic boundaries, and geological hazard points.

[0132] If the lithology on both sides of a section stratification point is significantly different, then the lithological properties of that section stratification point are the same as those in the field observation route. The lithological properties include: upper dip angle, upper dip direction, upper lithology, upper stratigraphic unit, lower dip angle, lower dip direction, lower lithology, lower stratigraphic unit, contact relationship, and stratification description.

[0133] If a geological structure appears at a section stratification point, then the structural properties of that section stratification point are the same as those in the field observation route.

[0134] If the stratigraphic units on both sides of a section stratification point are different, then the stratigraphic boundary point attribute of that section stratification point is the same as that in the field observation route.

[0135] If a geological hazard occurs at a section stratification point, the geological hazard point attribute of that section stratification point is the same as that in the field observation route.

[0136] In this embodiment, step S44 specifically includes:

[0137] S441: Determine the overall direction of the profile and draw the surface curve using the profile stratification point data and the additional attributes;

[0138] S442: Smooth the surface curve, draw the layer lines under the surface curve and fill in the lithological pattern to obtain the stratigraphic profile.

[0139] For details, please refer to Figure 4 The diagram illustrates the calculation of the overall orientation of the profile. By calculating the projected lengths of the line connecting the starting and ending points of the route on the x and y coordinates, the overall orientation of the profile is calculated using inverse trigonometric functions. The calculation formula is as follows:

[0140] C = arctan((∑L'·sinε)÷(∑L'·cosε)) where: L' - length of each conductor; ε - difference between the orientation of each conductor and the overall direction of the profile;

[0141] Figure 5 This refers to the Catmull-Rom spline. When drawing surface curves in a stratigraphic profile, since the information collected in the field is point data, curves cannot be drawn directly. Therefore, interpolation is needed between the point information on the surface to achieve the effect of simulating a curve. The system implementation uses the Catmull-Rom interpolation algorithm. When drawing a spline based on a set of points, it is often desirable for the line to pass through these points as smoothly as possible. A Catmull-Rom spline can be considered a special type of Bezier curve, and this Bezier curve guarantees that it will pass through all points from the second control point to the second-to-last control point. In other words, a Catmull-Rom spline requires at least four control points for control. Assume there are four points: P... -1 Given P0, P1, and P2, this invention constructs a curve P(t) from P0 to P1. Figure 5 P(t) is the curve to be solved as follows:

[0142] P(t) = at 3 +bt 2+ct+d

[0143] The parameter α controls the parallelism between the tail of the curve and the control point, with a value ranging from 0 to 1. To make the curve as smooth and beautiful as possible, the tangent at point P0 is parallel to P... -1 The line connecting P0 and P2 is parallel to the line connecting P1 and P2. Similarly, the tangent at point P1 is parallel to the line connecting P0 and P2. Therefore, control points P0 and P2 satisfy the following equations:

[0144]

[0145] because:

[0146] P'(t) = at 2 +bt+c

[0147] Combining the above formulas, we can obtain the following result:

[0148]

[0149] The curve can be obtained by substituting the parameters into the equation of curve P(t);

[0150] When connecting multiple points, simply select four consecutive points for calculation. For the first two points P0 and P1, point (2·P0-P1) and point P2 are generally taken as control points. Similarly, for the last two points P... n-1 P n Take P n-2 Sum of points (2·P) n -P n-1 ) as control points;

[0151] One of the most important steps in drawing a cross-section is drawing the stratification lines below the surface curve. The starting point of the stratification lines is on the surface curve, but the ending point needs to be determined by considering the apparent slope angle, the dip direction of the strata, the apparent dip angle, and the overall direction of the cross-section. The formulas for calculating the apparent slope angle (β') and the apparent dip angle of each stratum (α') are as follows:

[0152] β' = arctan(tanβ·cosε)

[0153] α' = arctan(tanα·cosε)

[0154] Figure 6 (a) shows the layered lines drawn when the viewing angle is greater than 0 (β' > 0°):

[0155] a. When the projection direction of the stratification tendency onto the overall section direction is consistent with the overall section direction, the following equation is satisfied:

[0156] |AC|<90°

[0157] The finish line is located in the second quadrant of the starting point, and its coordinates are:

[0158] (x+l·cosα',y-sinα')

[0159] b. When the projection direction of the stratification tendency in the overall profile direction is opposite to the overall profile direction and the stratification dip angle is smaller than the slope angle, the following equation is satisfied:

[0160] ((|AC|>90°)&(α′<β'))

[0161] The finish line is located in the first quadrant of the starting point, and its coordinates are:

[0162] (x+l·cosα',y+sinα')

[0163] c. When the projection direction of the stratification in the overall profile direction is opposite to the overall profile direction and the stratification dip angle is greater than the slope angle, the following equation is satisfied:

[0164] ((|AC|>90°)&(α′>β'))

[0165] The finish line is located in the third quadrant of the starting point, and its coordinates are:

[0166] (xl·cosα',y-sinα')

[0167] Figure 6 (b) shows the layered lines drawn when the slope angle is less than 0 (β' < 0°):

[0168] a. When the projection direction of the stratification tendency onto the overall section direction is opposite to the overall section direction, the following equation is satisfied:

[0169] |AC|>90°

[0170] The finish line is located in the third quadrant of the starting point, and its coordinates are:

[0171] (xl·cosα',y-sinα')

[0172] b. When the projection direction of the stratification tendency in the overall profile direction is consistent with the overall profile direction and the stratification dip angle is less than the slope angle, the following formula is satisfied:

[0173] ((|AC|<90°)&(α'<β'))

[0174] The finish line is located in the fourth quadrant of the starting point, and its coordinates are:

[0175] (xl·cosα',y+sinα')

[0176] c. When the projection direction of the stratification tendency onto the overall profile direction is consistent with the overall profile direction and the stratification dip angle is greater than the apparent slope angle, the following equation is satisfied:

[0177] ((|AC|<90°)&(α'>β'))

[0178] The finish line is located in the second quadrant of the starting point, and its coordinates are:

[0179] (x+l·cosα',y-sinα')

[0180] In drawing stratigraphic profiles, this invention utilizes image blending technology to achieve a series of irregularly shaped, interlaced lithological patterns. Taking the drawing of a semi-circular "oolitic dolomite" with a dip angle of 60° and a dip direction opposite to the overall profile direction as an example, the drawing steps are as follows:

[0181] Figure 7 (a) is an oolitic dolomite pattern unit. Find the pattern data of "oolitic dolomite" in the lithological pattern database and draw the lithological pattern unit. Figure 7 (b) is the area to be filled. First, extract the path of the area to be filled and the smallest rectangle containing the area. Then, fill the path in the smallest rectangle with any color (blue is selected here) to obtain the area to be filled. Figure 7 (c) is the lithological pattern background area. The area of ​​the lithological pattern background to be drawn is determined based on the filled area, dip angle, dip direction and the overall direction of the profile. Figure 7 (d) is the lithological pattern background. By setting the image blending mode, the pattern image of the filled area can be obtained by taking the intersection of the lithological pattern background and the filled area. Figure 7 (e) is the result of lithological pattern filling. After completing the lithological pattern filling, this filling result is drawn in the corresponding position on the stratigraphic profile to achieve the effect of stratigraphic profile pattern filling.

The additional attributes include: the angle between the traverse direction and the dip of the strata, the thickness of each stratum on each traverse, the stratum thickness, the group thickness, the cumulative thickness, the angle between the total direction and the traverse azimuth, the oblique horizontal distance, the stratification horizontal distance, the apparent horizontal distance, the stratification apparent horizontal distance, the apparent slope angle, the elevation difference, the cumulative elevation difference, the angle between the total direction and the dip angle, and the apparent dip angle. S44: Draw a stratigraphic profile using the profile stratification point data and the additional attributes; The steps for obtaining the attributes of the profile layer points in step S42 are as follows: The attributes of the profile stratification points are the same as those of any one of the observation points in the field observation route, including lithological observation points, structural observation points, stratigraphic boundaries, and geological hazard points. If the lithology on both sides of a section stratification point is significantly different, then the lithological properties of that section stratification point are the same as those in the field observation route. The lithological properties include: upper dip angle, upper dip direction, upper lithology, upper stratigraphic unit, lower dip angle, lower dip direction, lower lithology, lower stratigraphic unit, contact relationship, and stratification description. If a geological structure appears at a section stratification point, then the structural properties of that section stratification point are the same as those in the field observation route. If the stratigraphic units on both sides of a section stratification point are different, then the stratigraphic boundary point attribute of that section stratification point is the same as that in the field observation route. If a geological hazard occurs at a section stratification point, the geological hazard point attribute of that section stratification point is the same as that in the field observation route.
