Description

Technical Field

[0001] The present invention belongs to the field of DaoHeng code conversion, and in particular relates to a method, system, medium and equipment for converting DaoHeng code in field measurement. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] From traditional manual measurement to modern global navigation satellite system (GNSS) and real-time kinematic positioning (RTK) technology, the accuracy and efficiency of measurement have been significantly improved. In recent years, the popularity of mobile devices has provided new opportunities for the further development of measurement technology. In particular, field measurement solutions based on Android devices have become a new hot spot in the field of geodetic surveying and surveying engineering due to their intelligence, lightness and convenience.

[0004] In field surveying, traditional surveying methods mainly rely on professional surveying equipment, such as total stations and high-precision GNSS receivers. Although these devices have high measurement accuracy, they are large in size, heavy in weight, and complex in operation. They require professional personnel to operate and are difficult to meet the needs of modern and rapid measurement. In addition, the data collection and processing process of traditional surveying methods is relatively cumbersome, and real-time data sharing and dynamic adjustment cannot be achieved, which limits the efficiency and flexibility of measurement. In addition to the limitations of equipment, traditional field surveying also faces a cumbersome internal mapping process. After the field survey is completed, the surveyor needs to organize, proofread and map the large amount of collected ground feature information data. This process usually takes a lot of time and effort, which not only increases the workload, but also prolongs the overall cycle of the project. In addition, the complex ground feature coding conversion process also brings great challenges to surveyors. Surveyors need to convert ground feature information data according to specific coding rules, which requires not only rich professional knowledge, but also high carefulness and patience. Any small error may lead to deviations in the final results and affect the accuracy and reliability of the measurement. Summary of the invention

[0046] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0047] It should be noted that the following detailed descriptions are all illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0048] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0049] Terminology explanation:

[0050] Daoheng coding: used to draw plan and section drawings. Daoheng coding is a coding method used in engineering surveying, which helps to effectively record measurement data such as distance and elevation and present them in drawings, especially in the drawing of plan and section drawings of infrastructure such as roads and tunnels. The common format is angle ± height of the object.

[0051] Daoheng coding file: a coding format file suitable for the cross-section drawing of Daoheng software, the format is point name, coordinates, height, feature type code, Daoheng code, and remarks.

[0052] RTK receiver: RTK is a differential GPS technology that can provide real-time high-precision positioning services by receiving differential correction data sent by fixed base stations. RTK receivers are mainly used in fields that require high-precision positioning, such as geographic surveying and mapping, drones, and precision agriculture, with positioning accuracy reaching centimeter levels.

[0053] Ellipsoid height: Ellipsoid height refers to the vertical distance of a point on the ground relative to a reference ellipsoid (usually an approximate model of the earth). Unlike altitude (i.e., height relative to sea level), ellipsoid height is based on the ellipsoid model of the earth. Therefore, there will be some differences between the ellipsoid height and the true height of the terrain, especially in mountainous areas or areas with large terrain undulations.

[0054] Cumulative distance and offset distance: Cumulative distance refers to the accumulated distance from the starting point to a certain point, which is usually used in measurement or route design; offset distance refers to the lateral offset distance relative to a reference line or curve, which is used to judge the deviation between a certain point and the benchmark path.

[0055] Figure 1 It is a flow chart of a method for converting Daoheng code in field measurement in an embodiment of the present invention.

[0056] Combination Figure 1 and Figure 2 The field measurement Daoheng code conversion method in this embodiment may include:

[0057] S101, obtaining the original ground feature data collected by the RTK device and importing it into the Daoheng configuration file and the corner design file.

[0058] Before obtaining the original ground data collected by the RTK device, it also includes connecting (wireless or other communication methods) the RTK device and obtaining the RTK device's own information, which includes latitude, longitude, altitude, number of satellites, horizontal accuracy, elevation accuracy, and solution accuracy.

[0059] The original feature data includes the collection point number (i.e. the measurement point number), remarks, east coordinate, north coordinate, elevation, longitude, latitude, ellipsoid height, pole height, plane accuracy, elevation accuracy, feature height, feature remarks, and feature code; the implementation method is as follows:

[0060] RTK searches for satellite signals, places RTK at the target point, and avoids being around buildings and tree shades. The types of coordinate solutions include no solution, single point solution, differential solution, floating point solution, and fixed solution. Wait for the solution type to become a fixed solution to ensure measurement accuracy.

[0061] Open the object collection interface, wait for the positioning information to be synchronized to the current area, set the RTK collection accuracy, and ensure that the collected data meets the measurement requirements;

[0062] Select the feature type, enter the point number, remarks and pole height. The feature types include linear features and point features. Linear features include ditch and ridge, road, constant fence, power line, pipeline, house and vegetation. Point features include control points, water system facilities, independent trees, residential areas, pipeline facilities, power facilities, road facilities, industrial and mining facilities and public facilities.

[0063] If the RTK accuracy does not meet the requirements, wait for the RTK device to search for satellite signals to obtain higher positioning accuracy;

[0064] Place the RTK at the target feature point, select the feature type, enter the point number, remarks and pole height, select Collect point data on the Android device, and obtain high-precision real-time point coordinates; if the data collection or input is wrong, you can delete the point and collect it again; select Save point information to store the point data in the internal intermediate encoding form. The encoding form is: AA_BB_CC, where AA represents the feature code, BB represents the feature height, and CC represents the remarks.

[0065] After continuously collecting feature data, if there is no new target point to be collected, click the Save Point Information button. Including collection point number, remarks, east coordinate, north coordinate, elevation, longitude, latitude, ellipsoid height, pole height, plane accuracy, elevation accuracy, feature height, feature remarks, simple feature code, save data such as Figure 5 shown.

[0066] Among them, the corner design file is in txt format, which includes point name, east coordinate, north coordinate, and elevation;

[0067] Daoheng parameter configuration file is in txt format, which includes corner tower identification, corner tower branch identification, straight tower identification, direction pile identification, pile position tolerance, sideline width, and sideline width tolerance.

[0068] S102, reading original point records from the original feature data, filtering the original point data, calculating filtered coordinate data and saving the filtered coordinate data.

[0069] Among them, the original point record file is in txt format, which includes the collection point number, remarks, east coordinate, north coordinate, elevation, longitude, latitude, ellipsoid height, pole height, plane accuracy, elevation accuracy, feature height, feature remarks, and feature code.

[0070] Specifically, in step S102, during the screening of the original point data, the first point and the last point are judged separately.

[0071] Among them, the data in the original record array is traversed. If it is the first point, check whether the plane distance between the current point and the next point is less than the set distance (for example: 0.05m); if so, calculate the coordinates and height of the midpoint as a new point and save it. If the distance is greater than the set distance (for example: 0.05m), only save the coordinates and height of the current point;

[0072] Traverse the data in the original record array. If it is the last point, check whether the plane distance between the current point and the previous point is less than the set distance (for example: 0.05m); if so, calculate the coordinates and height of the midpoint as the new point and save it. If the distance is greater than the set distance (for example: 0.05m), only save the coordinates and height of the current point.

[0073] In the process of filtering the original point data, the data in the original record array is traversed. For the middle point, it is calculated whether the plane distance between the current point and the previous point and the next point is less than the set distance (for example: 0.05m). If so, the midpoint coordinates are calculated and merged. If not, the current point coordinates are saved.

[0074] S103, matching the first character of the tower pile name in the original feature data with the code in the Daoheng configuration file to determine the Daoheng code corresponding to the tower pile name.

[0075] According to the first character of the tower pile point name in the original feature information, it is matched with the code in the Daoheng configuration file to determine its specific feature type, such as corner, straight line, direction pile, offset pile or ordinary point, and the feature type code is set to `J` (corner), `Z` (straight line), `F` (direction pile), `P` (offset pile) or `C` (ordinary point).

[0076] S104, extracting the center line from the coordinate data in the original feature data according to the corner design file; judging the range of the measuring point according to the edge line width and edge line tolerance in the pre-configuration file and the vertical distance of the measuring point relative to the reference center line.

[0077] Wherein, in step S104, if the distance is less than the set edge line tolerance, it is considered that the measurement point belongs to the center line;

[0078] If the difference between the distance from the measuring point to the center line and the width of the edge line is within the edge line tolerance range and the distance is greater than 0, the point is located on the left edge line;

[0079] If the difference between the distance from the measured point to the center line and the edge width is within the edge tolerance range and the distance is less than 0, the point is located on the right edge.

[0080] S105, calculate the cumulative distance and offset distance of each measuring point, the vertical angle between the measuring point and the center line, and find the code that matches the Daoheng feature type code of each measuring point, add the corresponding angle and feature height to the corresponding feature information according to the Daoheng coding format requirements of different types of features, save the feature information and export the Daoheng coding file.

[0081] Calculate the angle between the measuring point and the center line in the vertical direction, and ensure that the angle is between -90 and 90 degrees. For each measuring point, determine whether the simple feature code matches the Daoheng feature type code, and add the angle and feature height to the feature information according to the Daoheng coding format requirements of different types of features (commonly angle ± feature height); and extract the point name, coordinates, height, and remarks from the original data in turn, and save them in combination with the matching feature type code and the calculated Daoheng code. For features such as street lights, flagpoles, traffic signs, and signal markers, use specific codes and remarks.

[0082] In step S105, the process of exporting the Daoheng coding file includes:

[0083] S1051, according to the initial feature sequence and the Daoheng coding format requirements, the measurement point name, coordinates, height, feature type code, Daoheng code and remarks information are sequentially included in the exported data;

[0084] S1052, by concatenating the character string, set the current time and project name as the encoding file name, and write the saved data into the Daoheng encoding file. According to the Daoheng software requirements, the file format is csv format, such as Figure 6 shown.
