And controlling the instruction; if the physiological characteristic of the user is not pre-existing the specified physiological feature, the instruction determining module ignores the user action feature to be executed, and does not perform the search control instruction process.

Here, obtaining the physiological characteristics of the user may refer to the facial features of the user, the color of the user, the length of the hair, the skin color of the user, the color of the lips, etc., or a combination of various physiological features for more accurate identification, etc. And the like are all within the scope of protection of the present invention.

As shown in FIG. 18, an embodiment of the present invention further provides a method for interactively capturing a UAV, which adopts the UAV interactive photographing system, and the method includes the following steps:

S100: the camera component acquires a captured image;

S200: The image processing module processes the captured image of the camera component to acquire a user action feature to be executed in the captured image;

S300: the instruction determining module searches for a corresponding control instruction in the control instruction library according to the user action feature to be executed;

S400: The instruction execution module controls the drone and/or the camera component according to the obtained control instruction.

When the control command includes a drone control command, a camera component control command, or other valid command, the determination process may adopt the flow shown in FIG. 19 to sequentially perform the determination and control, but is not limited to this manner. Others determine whether it is a camera component control command, and then determine whether it is a drone control command or the like, which falls within the scope of protection of the present invention.

As shown in FIG. 20, an embodiment of a specific UAV interactive photographing method is shown. First, determine the type of display. If it is an external display, you need to first connect the control unit to the external display through wireless communication to prepare for the rear control. Then, according to the correspondence between the gesture and the control instruction, the corresponding control instruction is searched for and the control is executed. As described above, the action features of the present invention are not limited to the one of the gestures, and the different actions of other body parts can also achieve the object of the present invention.

As described above, in order to distinguish between the drone control command and the camera component control command, it is possible to distinguish by different action characteristics. In addition, different control modules can also be implemented. For example, the control instruction may further include a first mode selection instruction and a second mode selection instruction respectively instructing the control component to enter the first mode and the second mode.

After entering the first mode, the received user action feature defaults to pointing to the drone control command, that is, the command determining module searches for the corresponding drone control in the control command library according to the user action feature. Commanding, and controlling the drone according to the obtained drone control command, and no longer executing the camera component control instruction; after entering the second mode, the received user action feature defaults to pointing to the camera component control An instruction, that is, the instruction determining module searches for a corresponding camera component control instruction in the control instruction library according to the user action feature, and controls the camera component according to the obtained camera component control instruction, and does not execute Camera component control instructions.

The camera assembly starts shooting, and the drone 200 rotates α to the other side at a preset speed at a preset speed in the same horizontal plane, thereby reaching a panoramic photo with an angle α, and the user is located at a designated position of the panoramic photo;

After the drone 200 stops rotating, the camera assembly stops shooting.

When n is 2, the user can be placed in the center of the panoramic photo. In practical applications, the angle α can be set as needed, and the position of the user in the panoramic photo can also be adjusted. For example, if the user is located in the left position, the drone can be rotated to one side by a/4, etc., and the shooting mode is adopted. Very flexible, and the success rate of taking panoramic photos is better, and taking photos is better.

As shown in FIG. 23, in another panoramic shooting mode, in the panoramic mode, the instruction execution module controls the drone and the camera assembly to perform panoramic photo shooting in the following manner:

The instruction execution module selects an positioning point between the camera assembly and the user 400, and uses the positioning point as a center to generate a first sector 701 of an angle α with a radius of L/m, and the object to be photographed is located at the center. On the arc of the first sector 701, where m is the second preset segmentation value, and m>1, α is the maximum angle of the preset panoramic shooting;

The instruction execution module generates a second sector 702 opposite to the first sector 701, the second sector The two sides of the 702 are respectively opposite extension lines of the two sides of the first sector 701, and the radius of the second sector 702 is (m-1) L / m, the angle is α;

The camera assembly starts shooting, and the drone 200 moves from one end of the arc of the second sector 702 along the trajectory of the arc to the other end of the arc;

After the drone 200 moves to the other end of the arc of the second sector 702, the camera assembly stops shooting.

As shown in FIG. 24, in another manner of panoramic shooting, in the panoramic mode, the instruction execution module controls the drone and the camera assembly to perform panoramic photo shooting in the following manner:

The instruction execution module calculates a distance L between the camera assembly and the user 400, that is, a distance indicated by a broken line connecting the user 400 and the drone 200 in the figure;

The instruction execution module selects an positioning point between the camera assembly and the user 400, and uses the positioning point as a vertex to generate a first isosceles triangle 703 with an apex angle α with a length of L/m as a waist. And the object to be photographed is located on a bottom edge of the first isosceles triangle 703, where m is a second preset segmentation value, and m>1, α is a preset panoramic shooting maximum angle;

The instruction execution module generates a second isosceles triangle 704 opposite to the first isosceles triangle 703, and the two waists of the second isosceles triangle 704 are respectively opposite to the two waists of the first isosceles triangle 703 To the extension line, and the length of the waist of the second isosceles triangle 704 is (m-1) L/m, and the apex angle is α;

The camera assembly starts shooting, and the drone 200 moves from one end of the bottom edge of the second isosceles triangle 704 along the trajectory of the bottom edge to the other end of the bottom edge;

After the drone 200 moves to the other end of the bottom side of the second isosceles triangle 704, the camera assembly stops shooting.

The shooting trajectories in FIG. 23 and FIG. 24 can be selected as needed, forming a panoramic photo by continuous shooting, or synthesizing a plurality of photos into one panoramic photo, and different selections of m and α can obtain different shooting ranges, and more flexibility. The drone can move according to the calculated preset trajectory, so that the camera component acquires different shooting positions and shooting angles.

When shooting with a drone, sometimes a certain preparation time is required, for example, a shooting countdown may be set, that is, the control command may further include a third mode selection instruction indicating that the control component enters the third mode, in the In the three mode, the instruction execution module controls the camera component to perform shooting after a preset waiting time. During the countdown process, the countdown time can be displayed by the display device, or the remaining preparation time can be indicated by other display lights or prompts.

The control instruction may further include a fourth mode selection instruction instructing the control component to enter a fourth mode, in the fourth mode, the instruction execution module detects a position of the user through the camera component, and controls the The drone and the camera assembly automatically move according to the position of the user, so that the camera assembly continuously captures the user. This enables automatic tracking of user shots, ensuring that the user is always within range.

Optionally, in the fourth mode, the instruction execution module may further acquire a position change acceleration of the user, and when the position change acceleration of the user exceeds a preset acceleration threshold, the instruction execution module sends an alarm signal to the outside. In this way, on the one hand, when the camera component cannot capture the user's position, the user can be alerted by the alarm, so that the user can actively come to the shooting range of the camera component; on the other hand, the fall detection can also be realized. When the user accidentally falls or feels uncomfortable, the alarm signal can be automatically sent to the outside. If the user does not cancel the alarm signal within a certain period of time, the mobile terminal of other users associated with the user or the emergency telephone can be further notified. While providing users with high-quality shooting, it also ensures the safety of users during use.

As shown in FIG. 26, further, considering that the user may cause the drone to hit other obstacles due to incorrect estimation or misoperation of the distance when controlling the drone, in order to protect the safety of the drone itself, At least one distance sensor may be disposed on the drone, the control component further includes an obstacle calculation module, and the obstacle calculation module is configured to acquire obstacle detection data of the distance sensor;

That is, the obstacle calculation module predicts according to the pointing direction of the control command after the obstacle is detected by the distance sensor, and if the drone performs the drone movement instruction, it may hit the obstacle. If so, the drone movement command is not executed, and the user is reminded that the distance is already less than the limit and there is a danger of hitting an obstacle.

With this embodiment, it is particularly suitable for shooting indoors. Due to the limitation of wall and ceiling in the room, and many other obstacles such as furniture and furnishings, this method can ensure the safety of the drone indoors through reliable calculation and danger prediction. Similarly, it can also be applied to the case where the drone is photographed outdoors. In an open space, the drone may move faster, and the user cannot predict the danger of the arrival. Therefore, in this way, Ensure the stability and reliability of the drone interactive shooting process.
