[Nine-day drone] The application of maps for research projects in Beijing

1 Project analysis

1.1 Project Name

The collection of geographic information related to the experimental field of "Beijing Desertification and Desertification Monitoring and Sandstorm Emergency Monitoring".

1.2 Customer background and needs

A professor at Beijing First University is conducting a research project on “Beijing Desertification and Desertification Monitoring and Sandstorm Emergency Monitoring”. The project address is in Beijing and it is necessary to obtain relevant data of the experimental field through drones for research.

1.3 Flight mission analysis

The project requires an area of ​​6.63 square kilometers for flight mapping, and the flight area is approximately rectangular, and the aerial survey is based on the geographic coordinates of the rectangular four corners. The coordinates are as follows:



The topography of the working area is a combination of mountains and plains. It is dominated by mountains and supplemented by plains. The average altitude is about 200 meters, the highest altitude is about 665 meters, and the lowest altitude is about 284 meters.

1.4 Precision requirements

The image data obtained by this aerial survey is applied to the topographic map with a scale of 1:2000, and the orthophoto image (DOM) and digital HD model (DEM) of the surveying area are required to be output, so aerial survey is required. The ground resolution of the image data is less than or equal to 0.3 m, and the ground resolution used in this flight is 0.25 m or less.

1.5 Equipment selection

The nine-day drone uses the intelligent aerial survey system Tiankui type 1 for the aerial survey mission. The three-mode dual-frequency GPS positioning is used for navigation and positioning. In addition to the 1:2000 topographic map, high precision can be obtained. The DOM image has a ground resolution of 0.21~0.25m, which can meet the aerial survey results required by this customer.


2 program design

The area of ​​the operation survey area is 6.63km2, the terrain is mainly mountainous, the average altitude is about 200m, the highest is about 665m, and the lowest is about 284m. According to the data of the customer demand, the Tiankui type 1 fixed wing is adopted in the flight plan. The man-machine is equipped with a 18.2 megapixel super-optical stabilization lens to ensure that the camera obtains high-quality data images with sufficient light input. The ground resolution is 0.25m, the relative altitude is 900m, and the heading overlaps 80%. The side overlap is 80%, and one flight operation task is designed. The average flight height is about 874m. According to the highest point and the lowest point elevation of the survey area, the ground resolution of the actual acquired image is calculated to be 0.21~0.24m. Meet the requirements of the customer's 1:2000 aerial survey data.
In this operation, the post-processing differential method is used for GPS data processing, and the known points near the surveying area are selected to set up the base station. In order to ensure the accuracy of the data required by the customer, the flying drone GPS adopts a sampling frequency of ≥10 Hz. The ground station adopts a sampling frequency of ≥10 Hz, and both of them observe data acquisition at the same time to ensure the accuracy of data collection.

3 Flight parameters

In this flight, according to the customer's needs combined with the pre-output results, the Tiankui 1 UAV system equipped with an optical stabilization lens was used for aerial survey. The specific parameters are as follows:



During the flight test flight, the flight data monitored by the ground station was normal, the cruising speed was basically maintained at 50km/h, the flight attitude was stable, and the three-angle angle deviation was < 2°. A total of 54 original images were taken, which took about 12 minutes. And confirm that all the image data is qualified and available, and the aerial survey aircraft operation is successfully completed.

4 results output

Add the data obtained by the flight to the professional software processing, and output the following results according to the customer's needs:
