The mapping planning problem of the aerial surveying device can be converted into a planning model in the management information system, and the aim is to maximize the mapping area function. The dynamic optimization model is a core module of the urban and rural aerial survey management information system, and dynamically coordinates the aerial survey equipment and the surveying and mapping domain through methods such as linear programming, nonlinear programming and dynamic optimization, so that the requirements on the number and the area of surveying and mapping points of the surveying and mapping domain are met on the premise of fully exerting the surveying and mapping capability of the unmanned aerial vehicle and saving the calling cost of the unmanned aerial vehicle, and high-quality and high-efficiency aerial survey management of the unmanned aerial vehicle is realized.

The system of the present invention is further illustrated by the following examples.
The X project has seven kinds of different survey and drawing points, two unmanned aerial vehicles in project area need be called now and carry out the mapping of taking photo by plane to each survey and drawing point, each survey and drawing point elevation difference in this urban and rural survey and drawing project place area can be ignored (not influencing unmanned aerial vehicle surveying and drawing ability), but the area of awaiting measuring of all kinds of survey and drawing points is different, it has the difference to occupy storage space, all kinds of survey and drawing points are also different apart from the distance at X project center (every survey and drawing work that an unmanned aerial vehicle accomplished a point location need return the project center and carry out the coordinate calibration, but not charge and data transmission work), there is the difference to unmanned aerial vehicle's continuation of the journey requirement. The data storage space of two unmanned aerial vehicles in the X project area is 1.02TB, the cruising distance is 40km, and the number of 7 types of surveying and mapping points, the area of a domain to be measured and the distance from the center of the project are shown in the table 1:
TABLE 1 survey and drawing point parameter information Table
Survey point classification A1 A2 A3 A4 A5 A6 A7
Data volume (GB) 48.7 52 61.3 72 48.7 52 64
Round trip distance (KM) 2 3 1 0.5 4 2 1
Number of survey points 8 7 9 6 6 4 8
According to the information, the total cruising distance that unmanned aerial vehicle needs to navigate is 89km, and the total cruising distance of two unmanned aerial vehicles is 80km, so two unmanned aerial vehicles can not accomplish the survey and drawing work of all survey and drawing point locations of this project area. Then, how to arrange the surveying and mapping work can be completed as many as possible, that is, the problem in the present embodiment can be converted into a planning problem (requiring that all point locations are completely surveyed and not incompletely surveyed) with the largest surveying and mapping area on the premise of meeting the requirements of the cruising distance and surveying and mapping capability of the unmanned aerial vehicle.
Under the condition that the number of the unmanned aerial vehicles is small, the models of the unmanned aerial vehicles are the same, and manual intervention is not needed to be carried out on the aerial survey scheme of the unmanned aerial vehicles, the problem can be converted into a linear programming problem. For convenience of measurement, Pi is the number of Ai-type containers loaded into the first flat car, and Qi is the number of Ai-type containers loaded into the second flat car.
A linear program can be obtained as follows:
Smax＝0.0487(P11+P21)+0.052(P12+P22)+0.061(P13+P23)+0.072(P14+P24)+0.0487(P15+P25)+0.052(P16+P26)+0.064(P17+P27)

the planning problem is solved using the AMPL program, the flow of which is shown in fig. 4.
Finally, the input is calculated by the AMPL program algorithm:
Figure BDA0001640442870000061
through the model calculation, the distribution conditions of mapping point positions of the first unmanned aerial vehicle and the second unmanned aerial vehicle are shown in table 2:

Survey point classification A1 A2 A3 A4 A5 A6 A7
First unmanned aerial vehicle 2 7 4 3 2 0 0
Second frame unmanned aerial vehicle 6 0 5 3 1 3 0
Total number of survey points 8 8 9 6 6 4 8
Number of remaining survey points 0 1 0 0 3 1 8
Thus, the occupied storage space is:
0.0487 x (2+6) +0.052 x 7+0.0613 x (4+5) +0.072 x (3+3) +0.0487 x (2+1) +0.052 x 3+0.064 x 0 ═ 1.98TB, which is the same as the result of system measurement, namely the maximum aerial survey storage capacity of the unmanned aerial vehicle reaches 1.98TB and the space utilization rate is 97% under the conditions of meeting the limit of the cruising ability and the limit of the storage ability of the unmanned aerial vehicle. Unmanned aerial vehicle surveying and mapping ability has obtained full play, has realized the maximize of aerial survey efficiency.
