Referring to fig. 1, fig. 1 is a schematic diagram illustrating steps of an intelligent three-dimensional topographic mapping method according to an embodiment of the present disclosure, as follows:
s100, acquiring a measuring area of the terrain to be drawn and data of the terrain to be drawn, and planning a surveying and mapping line according to the data;
in some embodiments, in order to improve the efficiency of topographic map surveying and mapping, in the surveying and mapping process, historical geographic data of a terrain to be surveyed, such as basic geographic data, ownership data, city update survey data, three old transformation patches, illegal patch survey data and other survey data, may be referred to, but since the historical geographic data have various sources, and the accuracy and timeliness of the data are not uniform, and the terrain to be surveyed also changes with the passage of time, the historical geographic data of the terrain to be surveyed cannot be directly used, especially buildings and terrain data such as roads, channels, enclosing walls, fences and the like serving as addressing lines, in embodiments of the present invention, the historical geographic data and a real scene three-dimensional model with high accuracy are compared and analyzed by a preset checking method to check whether the historical geographic data meet a preset accuracy requirement, and the historical geographic data meeting the preset accuracy requirement can only be used as reference geographic data that can be referred to.
Step S110, carrying out topographic map surveying and mapping on the survey area according to the surveying and mapping line, determining image control points distributed in the topographic map of the survey area, and processing the image control points according to the surveying specification;
in some embodiments, the image control points are empty imaging marker points, are mainly used for absolute orientation of three-dimensional modeling, and can be used for laying the positions and the number of the image control points in the range of the region to be measured according to a mapping line. The image control point layout mainly meets the precision requirement of aviation flight oblique photography, and the situation of repeated point layout in the same region is reduced as much as possible. Further, the above-mentioned image control point is laid in the region to be measured according to the survey and drawing line includes: uniformly distributing conventional image control points at equal intervals on a mapping line in a region to be measured according to a scale; the special image control points comprise image control points arranged at the overlapping part of the mapping line and image control points which are difficult to set; and laying the conventional image control points and the special image control points according to the laying condition.
Wherein, the netted laying of region (survey area) according to awaiting measuring of conventional image control point, and along survey and drawing the equidistant even setting on the circuit, the design of regional net that awaits measuring should be aimed at the survey area condition and combine the oblique photography subregion of aviation flying, aviation flying to divide the encryption survey area in the oblique photography direction, need avoid large tracts of land waters, independent island should form the survey area alone, avoid the condition that the image control point falls into water, and control the interval size of conventional image control point according to different topography scale
Step S120, inputting the processed image control points into a computer by utilizing computer information input, and carrying out accurate comparison through data checking management;
in some embodiments, after data statistics, computer data entry is performed, namely, three-dimensional drawing is performed on data size by using drawing software in a computer, the computer data entry comprises three links of data preparation, space-three encryption and modeling output, the data preparation mainly comprises the steps of sorting aviation image data, camera files, POS data and image control point data to enable the aviation image data, the camera files, the POS data and the image control point data to meet requirements of a software platform, the sorted data is loaded into live-action three-dimensional modeling software, and after the data entry and drawing of a three-dimensional graph, data checking management is required.
And S130, performing supplementary drawing on the initial drawing topographic map according to the image control points after the accurate comparison to generate a supplementary drawing topographic map.
In some embodiments, the terrain elements and feature elements identified in the live-action three-dimensional model are referenced to geographic data, the position information of the terrain elements and feature elements is determined, and an initial rendered terrain map of the terrain to be mapped is generated from the position information of the terrain elements and feature elements. It should be noted that the live-action three-dimensional model has the advantages of rich and real texture, good visual effect and high coordinate precision, so that the effect of topographic map mapping based on the live-action three-dimensional model is better. Exemplarily, by adjusting a view angle of a real-scene three-dimensional model, identifying terrain elements and ground feature elements in the terrain to be mapped, then determining position information of each terrain element and ground feature element in the terrain to be mapped by combining with reference geographic data, and mapping the terrain map, since the reference geographic data may not cover all the ground feature elements of the terrain to be mapped, for the remaining un-mapped elements in the terrain map, performing operations such as translation, rotation, zooming, and changing a view angle in the real-scene three-dimensional model, interpreting the remaining un-mapped terrain elements and ground feature elements, then performing supplementary mapping on the current terrain map according to the interpreted result, and finally generating an initial mapped terrain map of the terrain to be mapped.
Example 2
Referring to fig. 2, fig. 2 is a detailed step diagram of an intelligent three-dimensional topographic mapping method according to an embodiment of the present application, which is shown as follows:
step S200, scanning the measuring area of the terrain to be surveyed by using the three-dimensional laser scanning measuring system to obtain target data of the measuring area.
Step S210, obtaining the survey area of the terrain to be mapped, wherein the survey area comprises corner image control points and area image control points which are uniformly distributed in the survey area of the terrain to be mapped, and no high buildings are arranged around the corner image control points.
And S220, uniformly distributing conventional image control points at equal intervals on a surveying and mapping line in the terrain to be painted according to a scale.
And step S230, storing and collecting the topographic map of the survey area, extracting information of the stored topographic map, and then sorting and summarizing the extracted information.
And S240, comparing the data obtained by the three-dimensional laser scanning measurement system with the data input by the computer, and modifying the information input by the computer according to the result of the information comparison.

In some embodiments, it is not enough to directly perform mapping work based on the live-action three-dimensional model to complete the mapping of most terrain elements and feature elements, but because the unmanned aerial vehicle has the problems of unstable flight attitude, large image overlapping degree, difficulty in controlling the size of intersection angle and the like when acquiring the image of the terrain to be mapped, and meanwhile, in the mapping process of the unmanned aerial vehicle, the image pair needs to be continuously switched to complete the mapping process, thereby causing great deformation of the affected edge, so that the buildings which are shielded at the bottom layer in the live-action three-dimensional model, independent features which are small in area and incomplete in loading and the like cannot be identified, and therefore, the mapping process is not enough only depending on the live-action three-dimensional model. In order to further improve the accuracy of the topographic map mapping, the embodiment of the invention adopts a multi-sheet forward intersection algorithm to determine the position information of the ground object which cannot be identified.
