Detailed Description
Example 1
The embodiment provides a method for acquiring flight-limiting area information of an aircraft, as shown in fig. 1 and fig. 2, the method includes:
s11, receiving geographic position information and surrounding environment images of the position of the aircraft when the aircraft flies in a selected area, and establishing a first corresponding relation between the geographic position information and the surrounding environment images acquired at the same time.
And S12, analyzing the surrounding environment image according to a preset flight limiting area judgment standard to obtain flight limiting area information in the selected area.
And S13, establishing a second corresponding relation between the flight limiting area information and the corresponding geographical position information according to the first corresponding relation.
S14, after receiving one or more pieces of geographical position information and flight-limiting area information after establishing the second corresponding relation, judging whether flight-limiting area information corresponding to the received geographical position information is stored or not.
And S15, when the information is stored, updating the originally stored flight-limiting area information by using the newly received flight-limiting area information corresponding to the geographical position information.
And S16, when the information is not stored, storing the latest received flight limiting area information corresponding to the geographical position information.
Specifically, in step S11, the geographical location information of the location of the aircraft when the aircraft flies in the selected area may be acquired by a GPS module disposed on the aircraft, and longitude and latitude coordinate information of the location of the aircraft may be acquired as the geographical location information by the GPS module; the images of the surroundings of the aircraft during flight can be collected by one or more cameras arranged below the aircraft, for example, one or more cameras arranged below the aircraft can collect overhead images below the flight area of the aircraft, and one or more cameras arranged around the outside of the aircraft can obtain images of the front, the rear, the lower, or any one or more angles of the outside of the aircraft. The images are spliced by an image splicing method, so that the flight environment of the aircraft can be restored, and the image of the surrounding environment of the position of the aircraft in the selected area is obtained when the aircraft flies. In addition, in the flying process of the aircraft, each time point can simultaneously acquire the surrounding environment image and the geographical position information (such as the longitude and latitude acquired by the GPS module) of the time point, so that the geographical position information acquired at each same time point (expressed by the same time) is in one-to-one correspondence with the surrounding environment image in time, and accordingly, a first correspondence between the geographical position information at the same time and the surrounding environment image can be established, so that the corresponding surrounding environment image can be inquired through the fixed geographical position information, and the corresponding geographical position information can be obtained through the surrounding environment image, which is very convenient and fast.
In step S12, the predetermined criterion of the flight-restricted area includes information of a specific geographic object and a flight-restriction category corresponding to the information, where the specific geographic object includes at least one of an area set manually (for example, an area prohibited from flying defined at some special times or an area prohibited from flying by an aircraft defined by a user), a military restricted area, a water surface, a base station tower, a dense population area, or a dense building area, and the flight-restriction category includes at least one of a no-fly area, an area unsuitable for landing, a strong magnetic interference area, and an area unsuitable for flying. Specifically, the predetermined judgment standard of the flight-restricted area may determine the flight-restricted type of a military restricted area as a flight-restricted area, the flight-restricted type of a water surface as a landing zone unsuitable, the flight-restricted type of a base station transmission tower as a strong magnetic interference zone, and a population-dense area or a building-dense area as a flight-unsuitable area, except for the above-mentioned areas, other areas in the selected area are flight-suitable areas. The surrounding environment image is analyzed according to the preset judgment standard of the flight limiting area, so that the information of the flight limiting area in the selected area can be obtained by referring to the judgment standard, and the flight limiting area can be avoided when an aircraft route is established.
In step S13, since the flight restriction region information in the selected region is obtained by analyzing the surrounding image according to the predetermined flight restriction region determination criterion, therefore, the flight restriction region information is the description information of the flight restriction region in the surrounding environment image, and the surrounding environment image and the geographical position information have a first corresponding relation, so that, according to the first corresponding relation, a second corresponding relation between the flight-limiting area information and the corresponding geographical position information can be established, through the second corresponding relationship between the information of the flight-limiting area and the corresponding geographic position information, people can know which position (latitude and longitude coordinate information) has a flight-limiting area (such as a military restricted area, a water surface, a base station launching tower, a densely populated area or a building-dense area, a flight-forbidden area defined by a user according to requirements and other specific geographic objects) and what the type of the flight-limiting area is. For example, if a water surface exists in the selected area, people can acquire the longitude and latitude of which the water surface exists, similar information belonging to the area which is not suitable for landing, and the aircraft cannot be allowed to land when flying to the water surface when the air route and the control instruction of the aircraft are set.
In the steps S14-S16, the newly received flight-limiting area information corresponding to the geographic position information is used for updating the originally stored flight-limiting area information, so that the flight-limiting area information can be updated in time, the accuracy of the flight-limiting area information corresponding to the stored geographic position information is ensured, and a reliable basis is provided for setting an accurate air route for an aircraft user.
Specifically, the steps S11-S16 may be executed by an APP built in the smartphone, or may be executed by the server.
According to the method for acquiring the flight-limiting area information of the aircraft, the surrounding environment image is analyzed according to the preset flight-limiting area judgment standard, so that the flight-limiting area information in the selected area can be obtained, the corresponding relation between the geographical position information in the selected area and the surrounding environment image is established in advance, the geographical position information corresponding to the flight-limiting area information can be easily inquired according to the corresponding relation, and the corresponding relation between the geographical position information and the surrounding environment image is established.
Preferably, as shown in fig. 3, the step S12 may include:
s121, identifying all geographic object information in the surrounding environment image.
And S122, comparing each piece of identified geographic object information with specific geographic object information in the preset flight limiting area judgment standard one by one.
S123, if the geographic object information is matched with the flight limiting region judgment standard, extracting a flight limiting type corresponding to the specific geographic object information matched with the geographic object information from the flight limiting region judgment standard; and taking the geographic object information and the flight restriction type corresponding to the specific geographic object information matched with the geographic object information as flight restriction area information in the selected area.
Specifically, an image recognition technique may be used to recognize all the geographic object information in the surrounding image, where the geographic object information is information of an object that can be recognized in a three-dimensional space, for example, the recognized object is a ground building such as a house, or a natural landscape such as a mountain, a river, or the like. The geographic object information can clearly describe information such as ground attachments and the like in the surrounding environment image, so that people can clearly know the three-dimensional space three-dimensional structure in the selected area contained in the surrounding environment image and know the flight environment in the selected area. Each geographic object information is compared with the specific geographic object information in the preset flight area judgment standard one by one, if one or more specific geographic objects are included, the fact that the geographic object information matched with the specific geographic object information exists in the geographic object information is indicated, the fact that one or more specific geographic objects exist in the geographic object information of the surrounding environment image and a flight-limiting area exists can be judged, and the flight-limiting type corresponding to the matched geographic object information can be easily obtained due to the fact that the corresponding relation exists between the specific geographic object information in the judgment standard and the flight-limiting type, and the flight-limiting area information (the geographic object information and the flight-limiting type) is obtained.

And S22, judging whether a sharing request is received.
And S23, if so, confirming the geographical position information corresponding to the sending area of the sharing request.
And S24, inquiring and feeding back the flight limiting area information corresponding to the geographic position information.
Specifically, the sharing request may be performed by an APP built inside the smartphone, and the steps S21-S24 may be performed by the server.
In the method for sharing information of the flight-limiting area of the aircraft in this embodiment, the correspondence between a plurality of pieces of information of the flight-limiting area and corresponding geographic positions is collected, and after receiving a sharing request, the information of the flight-limiting area of the geographic position information corresponding to the sending area of the sharing request is fed back, so that multi-party information sharing is realized.
