[0025] Nowadays, the use of aircraft equipped with cameras for shooting is becoming more and more popular among video content creators. In the use scenario of existing aircraft using fixed shooting subjects to shoot complex camera movements, in order to obtain better shooting effects, it is usually necessary to repeat the flight camera movement shooting many times to ensure better shooting conditions, such as weather, lighting, shooting subjects and other factors. However, in actual shooting operations, shooting conditions are usually unstable, such as real-time changes in weather, some special weather may be fleeting, and complex camera movements are difficult to have a high shooting success rate. In addition, the shooting subject may also be the operator of the aircraft, and it is difficult to maintain a better demeanor when operating the aircraft. In summary, in order to obtain a higher success rate and more efficient shooting experience, the function of being able to store real-time camera movement trajectories and repeatedly shoot pictures according to the stored camera movement trajectories will become extra practical.

[0026] In view of this, an embodiment of the present application provides an aircraft video shooting method and an aircraft to achieve automatic shooting and improve shooting effects.

[0027] See also Figure 1 , an embodiment of the present application provides an aircraft 100, and the aircraft 100 has a flight function. The aircraft 100 may include a camera 110, a main controller 120, a flight controller 130, and a video processor 140. The camera 110 may be installed at at least one end of the aircraft 100, such as the front end, and the camera 110 may shoot a video or image of at least one end of the aircraft 100, such as the front end. In some embodiments, the camera 110 may be connected to the fuselage of the aircraft 100 through a gimbal structure so that the camera 110 has higher shooting stability during the flight of the aircraft 100. In some embodiments, the camera 110 may shoot and provide original images after being started.

[0028] The main controller 120 is connected to the camera 110, the flight controller 130 and the video processor 140 respectively, and is used to send and receive signals and information of these connected components to realize control and information processing functions. The flight controller 130 is used to control the flight of the aircraft 100, such as the flight distance, flight speed, target position, flight trajectory, etc. The video processor 140 is used to process the original picture taken by the camera 110 and obtain the target picture. Among them, the processing of the original picture by the video processor 140 may include but is not limited to rotation, speed increase, editing video frames, and generating other video effects.

[0029] In some embodiments, the aircraft 100 may also be paired with a remote controller 200, and the remote controller 200 may wirelessly communicate with the aircraft 100. The aircraft 100 may be, but is not limited to, an unmanned aircraft, a drone, an unmanned aircraft, etc. The remote controller 200 is a remote control device that matches the aircraft 100 and can be used to remotely control the flight of the aircraft and the shooting of the camera. The remote controller 200 may be held by a user or operator and may send instructions to the aircraft by wireless transmission, thereby controlling the flight of the aircraft and the shooting of the camera.

[0030] In some embodiments, the remote controller 200 may include a control component 210 and a display component 220.

It can be understood that the map software can be an application installed by the display component 220 or the control terminal.

[0031] See also Figure 2 , Figure 2 The following is a flow chart of a method for shooting video of an aircraft provided in an embodiment of the present application. Figure 2 The aircraft video shooting method shown can be Figure 1 The aircraft 100 shown performs and includes the following steps.

[0032] Step S201: Acquire the target position of the aircraft.

[0033] In some embodiments, the aircraft 100 is turned on and preset parameters are set through the main controller 120. In some embodiments, the preset parameters may include the flight distance s, the flight speed v, and the number of rotations n of the target screen of the aircraft 100. In some embodiments, the camera 110 may be turned on at the same time when the aircraft 100 is turned on, and the original screen is captured by the camera 110, and the aircraft 100 is controlled to fly forward or backward toward the center direction of the current original screen. In some embodiments, during the process of the aircraft 100 flying forward or backward toward the center direction of the current original screen, the video or original screen captured by the camera 110 may produce a forward or backward video effect.

[0034] In some embodiments, the aircraft 100 can calculate the target position P through the main controller 120. In some embodiments, the target position P is the target position that the aircraft 100 needs to reach during flight shooting. If the aircraft 100 is flying toward the center of the current original image, the target position P can be calculated using formula (1):

[0035] Formula (1)

[0036] Among them, T1 is the rotation matrix from the camera system to the aircraft system, T2 is the rotation matrix from the aircraft system to the aircraft navigation system (or control system), and s is the flight distance of the aircraft.

[0037] In some embodiments, if the aircraft 100 flies backward toward the center of the current original image, the target position P' can be calculated by formula (2):

[0038] Formula (2)

[0039] Among them, T1 is the rotation matrix from the camera system to the aircraft system, T2 is the rotation matrix from the aircraft system to the aircraft navigation system (or control system), and s is the flight distance of the aircraft.

[0040] It can be understood that when the aircraft 100 flies forward or backward toward the center direction of the current original picture, the target position P can be located in the center direction of the current original picture.

[0041] Step S202: Control the aircraft to fly toward the target location and shoot the original image through the camera.

[0042] In some embodiments, the flight controller 130 can be used to control the aircraft 100 to start the flight and the camera 110 can be used to synchronously shoot the original picture. The aircraft 100 can fly toward the target position P, and the camera 110 can shoot the original picture during the flight. In some embodiments, the current position of the aircraft 100 can be the starting point of the flight distance s, and the target position P can be the end point of the flight distance s. The flight speed v can be the speed of the aircraft 100 during the flight of the flight distance s, which can be uniform motion or non-uniform motion. In some embodiments, the aircraft 100 flies at a uniform speed during the flight to the target position P. The number of rotations n of the target picture can be the number of rotations required for the target picture to rotate during the flight of the aircraft 100 to the target position P, such as 5, 8, 10, etc., which are not limited in this application. It can be understood that when the aircraft 100 flies to the target position P, the target picture completes the rotation of the number of rotations n, and the target picture rotates to the origin position.

[0043] It is understood that the aircraft 100 can obtain the original picture by shooting at the target position P through the camera 110 at the initial position (i.e., the current position). In some embodiments, when the aircraft 100 flies forward or backward toward the center direction of the current original picture, the video or original picture shot by the camera 110 can produce a forward or backward video effect.

[0044] Step S203: cutting out the target image from the original image.

[0045] In some embodiments, the original image captured by the camera 110 can be processed by the video processor 140 to obtain the target image. Figure 3 , Figure 3 A schematic diagram of an original picture 12 and a target picture 14 is shown. The target picture 14 may be located in the maximum rotatable area of ​​the original picture 12. In some embodiments, the original picture 12 includes an inscribed circle 13, and the area of ​​the inscribed circle 13 may be the maximum rotatable area of ​​the target picture 14 in the original picture 12. It can be understood that the camera 110 does not need hardware rotation during the flight of the aircraft 100, so the direction of the original picture 12 remains unchanged and does not rotate, while the target picture 14 may be the central area of ​​the original picture 12 and may be rotatable relative to the original picture 12 along the inscribed circle 13, so that the target picture 14 may produce a video effect of picture rotation.

[0046] Please also read Figure 4 , Figure 4A schematic diagram of the size parameters of the original picture 12 and the target picture 14 is shown. The original picture 12 is spread along the xy plane and is a rectangular plane with a width w and a height h, so that the original picture 12 has a preset aspect ratio k=w / h. The target picture 14 is a rectangular plane with four vertices a, b, c, and d (which can be represented as a rectangular frame abcd), wherein the vertex lines ab and cd can be the width of the target picture 14, and the vertex lines bd and ac can be the height of the target picture 14. In some embodiments, the target picture 14 has a preset aspect ratio k=ab / bd. It can be understood that the target picture 14 has the same preset aspect ratio as the original picture 12, so that the target picture 14 can cut the original picture 12 in proportion, without causing the picture ratio to be out of balance or distortion due to cutting, and the picture quality of the target picture 14 is guaranteed. In some embodiments, the four vertices a, b, c, and d are respectively located on the inscribed circle 13. In some embodiments, the original image 12, the inscribed circle 13 and the target image 14 are concentric structures, having the same center point o, and the line connecting the center point o and any vertex of the four vertices a, b, c, and d, for example, ob, is the radius of the inscribed circle 13, and the radius of the inscribed circle 13 is half of the height of the original image 12, that is, ob=h / 2. In some embodiments, the width ab of the target image 14 can be calculated by formula (3):

[0047] Formula (3)

[0048] Wherein, h is the height of the original picture 12, and k is the preset aspect ratio.

[0049] The height bd of the target image 14 can be calculated by formula (4):

[0050] Formula (4)

[0051] Wherein, h is the height of the original picture 12, and k is the preset aspect ratio.

[0052] Step S204: controlling the target image to rotate.

[0053] In some embodiments, the rotation of the target image 14 can be controlled by the video processor 140. In some embodiments, please refer to Figure 4, the angle θ between the central axis of the original picture 12 and the target picture 14 represents the rotation angle θ of the target picture 14 relative to the original picture 12, and the rotation angle θ of the target picture 14 can be expressed as the rotation angle of the current frame of the target picture 14 relative to the original picture 12 at the current flight time or the current flight moment. It can be understood that during the flight of the aircraft 100 toward the target position P, the video processor 140 controls the target picture 14 to rotate continuously to produce a rotating video effect, then the current frame of the target picture 14 corresponding to each flight time or flight moment of the flight process has a corresponding rotation angle θ relative to the original picture 12. In some embodiments, in the flight distance s of the aircraft 100 flying toward the target position P, the flight time t can be t=s / v. Where s is the flight distance and v is the flight speed. Then the rotation angle θ of the target picture 14 can be calculated by formula (5):

[0054] Formula (5)

[0055] Wherein, s is the flight distance of the aircraft, v is the flight speed of the aircraft, n is the number of rotations of the target image, and t is the current flight time or flight moment of the aircraft. It can be understood that the current flight time or flight moment of the aircraft can be the Nth time unit of the flight of the aircraft 100, such as the Nth second. The calculated rotation angle θ of the target image 14 can be the rotation angle of the current frame of the target image 14 corresponding to the current flight time or flight moment relative to the original image 12.

[0056] In some embodiments, the current frame of the target screen 14 corresponding to each flight time or flight moment of the aircraft 100 during the flight process has the coordinates of the corresponding four vertices a, b, c, and d, and the current frame of the target screen 14 can be obtained from the coordinates of the four vertices a, b, c, and d. Among them, the vertex a of the target screen can be calculated by formula (6):

[0057] Formula (6)

[0058] The vertex b of the target screen can be calculated by formula (7):

[0059] Formula (7)

[0060] The vertex c of the target screen can be calculated by formula (8):

[0061] Formula (8)

[0062] The vertex d of the target screen can be calculated by formula (9):

[0063] Formula (9)

[0064] Wherein, θ is the rotation angle of the target image 14 , w is the width of the original image 12 , h is the height of the original image 12 , and k is the preset aspect ratio.

[0065] In some embodiments, the video processor 140 cuts the area enclosed by the four vertices a, b, c, and d from the current frame of the original picture 12 to obtain the current frame of the target picture 14 .

[0066] Step S205: obtaining the superimposed effect of the target image moving forward, backward and rotating when the aircraft is flying to the target position.

[0067] In some embodiments, the current frame of the target screen 14 corresponding to each flight time or flight moment of the aircraft 100 during the flight process is processed by the video processor 140 to continuously form a video effect of advance, retreat and rotation superposition. It can be understood that in the process of the aircraft 100 flying to the target position, the aircraft 100 moves forward and backward toward the target position, resulting in an advance and retreat video effect, and then through the rotation control of the target screen, a superimposed video effect of advance, retreat and rotation is generated. In some embodiments, when the aircraft 100 flies to the target position, the target screen completes the rotation of the number of rotations, and the target screen is rotated to the origin position.

[0068] When the aircraft 100 is flying toward the target position, the camera 110 captures the original image and cuts the target image from the original image. By controlling the rotation of the target image, the aircraft 100 obtains a superimposed video effect of the target image advancing, retreating, and rotating during the flight to the target position. When the aircraft 100 flies to the target position, the video shooting and the superimposed video effect of the target image advancing, retreating, and rotating can be completed. There is no need to set up additional hardware on the aircraft 100 to realize the rotation of the target image. While effectively controlling the cost, rich video shooting effects can be obtained, thereby improving the user experience.

[0069] See also Figure 5 , Figure 5 This is a flow chart of a method for shooting video of an aircraft provided by another embodiment of the present application. For example, Figure 5 The aircraft video shooting method shown can be Figure 1 The aircraft 100 shown performs and includes the following steps.

[0070] Step S501: Acquire the target position of the aircraft.

[0071] For detailed description of step S501, please refer to Figure 2 Step S201 and Figure 1 The relevant description will not be repeated here.

[0072] Step S502: Control the aircraft to fly toward the target location and shoot the original image through the camera.

[0073] For detailed description of step S502, please refer to Figure 2 Step S202 and Figure 1 The relevant description will not be repeated here.

[0074] Step S503: cropping the target image from the original image.

[0075] For detailed description of step S503, please refer to Figure 2 Step S203 and Figure 1 The relevant description will not be repeated here.

[0076] Step S504: controlling the target picture to rotate and acquiring the current frame of the target picture.

[0077] For detailed description of step S504, please refer to Figure 2 Step S204 and Figure 1 The relevant description will not be repeated here.

[0078] In some embodiments, the current frame of the target picture 14 corresponding to each flight time or flight moment of the aircraft 100 during the flight process is obtained through the method of step S204 to form a material library of video frames.

[0079] Step S505: Edit the current frame of the target picture.

[0080] In some embodiments, the current frame of the target image can be edited by the video processor 140, such as encoding, speed doubling, beautification, filters and other video effects. In other embodiments, other types of editing such as frame extraction and interleaving can also be performed on the current frame of the target image.

[0081] Optionally, step S505 may also be omitted, that is, the user or operator does not edit the current frame of the target picture, and the method directly proceeds from step S504 to step S506.

[0082] Step S506: Obtain the superimposed effect of the target image moving forward, backward and rotating when the aircraft is flying to the target position.

[0083] For detailed description of step S506, please refer to Figure 2 Step S205 and Figure 1 The relevant description will not be repeated here.

[0084] Please also read Figure 6 In some embodiments, the cropping target image cropping frame, i.e. Figure 4The rotation direction of the rectangular frame abcd' shown is opposite to the rotation direction of the content of the target screen 14, so as to obtain the effect of video frame rotation. Exemplarily, when the target screen cropping frame (i.e., the rectangular frame abcd) rotates in a first direction (which may be counterclockwise), the content of the target screen 14 may rotate in a second direction (which may be clockwise), thereby producing the effect of video frame rotation.

[0085] Step S507: End the video shooting of the aircraft and control the aircraft to hover.

[0086] In some embodiments, after the aircraft 100 flies to the target position P, the aircraft 100 is controlled to hover at the target position P to await further operations by a user or operator.

[0087] In some embodiments, during the flight of the aircraft 100 toward the target position P, the main control unit 120 may also be provided with a progress detection mechanism, which may detect the progress of the flight to the target position P through the flight controller 130, and detect the progress of completing the number of rotations n of the target screen through the video processor 140. When the aircraft 100 flies to the target position P, the number of rotations n of the target screen is completed at the same time.

[0088] In some embodiments, the aircraft 100 may store a safety mechanism for video shooting. When the aircraft 100 is performing video shooting and any condition in the safety mechanism is triggered, the aircraft 100 may immediately end the video shooting to ensure the safety of the aircraft 100. In some embodiments, the safety mechanism for video shooting may include the following conditions: loss of positioning signal (GNSS signal), triggering of a higher priority function, triggering of cancelling the execution of video shooting, and / or the flight of the aircraft 100 touching a no-fly zone, a restricted-fly zone, or an electronic fence. Among them, the higher priority function may include but is not limited to a low-battery return function, a one-key return function, and / or a lost connection return function set by the aircraft 100. The triggering of cancelling the execution of video shooting can be triggered by the user or operator through the control component 210 of the remote controller 200 or the display interface control of the display component 220 to cancel the execution of video shooting.

[0089] In the aircraft video shooting method of the embodiment of the present application, the aircraft 100 shoots the original picture through the camera 110 while flying toward the target position, and crops the target picture from the original picture. By controlling the rotation of the target picture, the aircraft 100 obtains the superimposed video effect of the advance, retreat and rotation of the target picture during the flight to the target position. When the aircraft 100 flies to the target position, the video shooting and the superimposed video effect of the advance, retreat and rotation of the target picture can be completed, and the current frame of each target picture can be further edited, thereby further enriching the video effect and further improving the user experience.
