Problems solved by technology
[0003] At present, in the implementation process of field landscape agricultural pattern modeling, due to the strict accuracy requirements of the planting pattern boundary and the mixed planting of different types or varieties of crops, it is difficult for existing planting machines to complete the task, and only manual methods can be used for field modeling Although the design and planting construction has been assisted by GPS and other advanced technical means, it is still time-consuming and labor-intensive with a high error rate

Embodiment Construction
[0035] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0036] Such as figure 1 As shown, the realization method of field crop landscape pattern based on high-precision positioning UAV aerial sowing includes the following steps:
[0037] Step 1. Use the GIS system or GPS positioning method to determine the boundary data B1 of the field to be operated, such as Figure 8 shown;
[0038] Step 2, determine the boundary data B2 of the landscape pattern, such as Figure 9 Flag pentacle shown;
[0039] Step 3. According to the size and orientation of the field boundary data B1, adjust the size and orientation of the landscape pattern boundary data B2 by means of scaling, translation, rotation, etc., and obtain the regional boundary data B3 after the fusion of the two, as F...

The invention discloses a method for realizing a field crop landscape pattern based on a high-precision positioning unmanned aerial vehicle. Use the GIS system or GPS positioning method to determine the boundary data of the field to be operated, and determine the boundary data of the landscape pattern according to the requirements; combine the field boundary data and landscape pattern data to obtain the boundary data of different regions, convert it into a route trajectory, and use navigation Point simplification algorithm processing, get streamlined route trajectory, use UAV with inkjet / powder spray function, fly and spray according to route trajectory, mark along the projection line of route trajectory on the surface, and get dominant surface pattern; Separate regions, plan and streamline aerial sowing routes, use aerial sowing drones to load preset crop seeds of different types or varieties, implement aerial sowing operations according to routes, and let seeds fall into specific areas; wait for germination and emergence, timely field management, The crop landscape pattern can be obtained. The invention is suitable for the construction of creative landscape patterns of field crops.
Description
technical field [0001] The invention relates to the field of agricultural machinery, in particular to a method for realizing field landscape patterns based on high-precision positioning drone aerial sowing. Background technique [0002] With the continuous improvement of people's living standards and the promotion and implementation of the rural revitalization strategy and the construction of beautiful new countryside, my country's creative landscape agriculture has developed greatly in recent years. People hope that the crops in the farmland can not only increase their yield and increase their income, but also show some kind of visual effect of calligraphy and painting landscape modeling during their growth period, so as to achieve the purpose of creating an environmental atmosphere and advertising. Due to the needs of tourist attraction development and advertising, examples of creative landscape agriculture such as sea of rapeseed flowers and rice field landscapes are co...
