UAV aerial survey
In 2016, the company took the lead in the province to introduce the world's leading, completely free image control Sirius UAV aerial mapping system, equipped with EPS naked-eye 3D mapping system, getting rid of the traditional mode of vertical measurement, greatly improving the efficiency of engineering measurement The main advantages of this system:
1) High precision, the UAV has a built-in 100HZ RTK system, and the elevation accuracy can reach 5 cm, which solves the problem of inaccurate elevation of the UAV.
2) There is no need for any image control points, and the only UAV that can achieve complete image-free control at present.
3) Hand-thrown to take off, glide and fall, easy to operate.
4) Highly intelligent, the route is automatically set, no need to manually arrange the route, and the terrain can be affixed to the fixed altitude.
5) Image processing does not require the air three encryption process of traditional aerial surveys, importing image data and POS information into processing software, fully automatic processing, and outputting DEM, DOM, point cloud and tile data.
6), the line drawing is collected in a naked-eye 3D environment, without the need for 3D glasses and handwheel casters in the traditional vertical measurement mode.
After rapid exploration and production tests, the company has gradually formed a set of Lupin's characteristic Sirius UAV high-efficiency aerial survey program. In just two years, the single aircraft has flown more than 1,000 sorties and the cruising range exceeds 20,000 km. It is used nationwide during busy periods. Six Sirius UAVs work together, and they have basically completely replaced the manual large-scale field surveying work.
Typical project | Route length: 100 kilometers
Surveying and mapping width: 500 meters
Surveying and mapping width: 500 meters
|
Project implementation | 1. The aviation team quickly entered the site to conduct site surveys and preparations for operations;
2. Flying 6-10 sorties per day, obtaining images of 10-20 kilometers;
3. The image of the same day is transmitted to the company at night, and the image is processed overnight to generate Dom, Dem, and original point cloud;
4. On the second day, the DEM and DOM data will be distributed to the operators, and DLG collection will be carried out in the office, with a work efficiency of 1km/person/day (plain and hilly terrain, full element collection);
5. Import high-definition images into the tablet, and arrange for field staff to adjust and draw.

Construction period | 1. As soon as the third day of accepting the task, the design unit can provide image data and line drawing process data one after another;
2. There are 30 flight sorties, which takes one week, and the entire operation cycle is easily completed in 20 days.
