The first embodiment of the tracking shooting method comprises the following steps:
referring to fig. 2, an embodiment of the invention provides a tracking shooting method, which is characterized in that: the method comprises the following steps:
step S1, the shooting terminal 1 establishes communication connection with the shooting auxiliary carrier 2 through wired communication or wireless communication;
specifically, wired communication: the shooting terminal 1 is provided with a communication port, the shooting auxiliary carrier 2 is provided with a data line, and when the shooting terminal 1 and the shooting auxiliary carrier 2 need communication connection, a terminal of the data line is inserted into the communication port, so that the communication connection between the shooting terminal 1 and the shooting auxiliary carrier 2 can be established.
Wireless communication: the shooting auxiliary carrier 2 is provided with a wireless communication module, in this embodiment, the wireless communication module is a second bluetooth communication module, the shooting terminal 1 includes a first bluetooth communication module, and when the shooting terminal 1 needs communication connection with the shooting auxiliary carrier 2, the second bluetooth communication module is started and communication connection is established with the first bluetooth communication module of the shooting terminal 1, and then communication connection between the shooting terminal 1 and the shooting auxiliary carrier 2 is established. Optionally, when the photographing terminal 1 and the photographing auxiliary carrier 2 are in the same wireless network (for example, WiFi), the photographing terminal 1 and the photographing auxiliary carrier 2 may also be in communication connection via the wireless network.
Step S2, the user inputs a tracking shooting instruction to the viewing terminal 4, and the viewing terminal 4 receives the tracking shooting instruction input by the user and feeds the tracking shooting instruction back to the server 3;
in step S3, the server 3 transmits a tracking shooting instruction to the shooting terminal 1, and the shooting terminal 1 enters a tracking shooting mode to perform a shooting operation upon receiving the tracking shooting instruction, and obtains tracking video information.
Preferably, the tracking video information in step S3 includes: when at least two target objects exist in a shooting area, the shooting terminal 1 collects face contour information of each target object;
when the collected face contour information is consistent with the pre-stored face contour template, the target object corresponding to the face contour information is continuously tracked and shot, and the tracking and shooting of the rest target objects are stopped.
As an improvement to the present embodiment, in another embodiment, the tracking video information in step S3 includes: step S30, confirming the photographing area of the photographing terminal 1 itself, and confirming at least one target object within the photographing area. In the present embodiment, the current shooting area of the shooting terminal 1 is the shooting area. In this embodiment, a specific manner of confirming at least one target object in the shooting area may be: outputting and displaying a current photographic image; receiving at least one touch operation input by a user on a display screen; confirming that an object corresponding to each touch operation is a target object; the method can also comprise the following steps: before tracking shooting, shooting to obtain an image, and analyzing the image to obtain at least one target object; the method can also comprise the following steps: when tracking shooting is carried out, a first frame image is obtained through shooting, and the first frame image is analyzed to obtain at least one target object.
Further, in this embodiment, the priority of at least one target object may be determined according to the touch operation input order. Specifically, when there are A, B, C, D four target objects, a is the highest in priority, the priority is gradually lowered, and D is the lowest in priority. Therefore, during shooting, when A and D cannot be simultaneously present in the shooting area, A is tracked and D is discarded. Preferably, in the present embodiment, one target object is confirmed within the photographing region. In step S31, when the shooting terminal 1 detects that the at least one target object moves, the server 3 controls the motion of the shooting auxiliary carrier 2 so that the at least one target object is in the shooting area. When the movement of the at least one target object is detected, the movement of the photographing auxiliary carrier 2 is controlled so that the at least one target object is within the photographing region. The embodiment automatically detects the target object through the shooting terminal 1, and automatically controls the motion of the shooting auxiliary carrier 2 according to the detection result, so that the automatic shooting of the tracking video is realized, and the automatic performance of the tracking video shooting is improved.
Further, after the step S31, a step S40 is included, in which the photographing terminal 1 collects motion information of each target object when at least two target objects exist in the photographing region. In step S41, when the motion information matches the preset operation information, the target object corresponding to the motion information continues to be track-shot, and the track-shot of the remaining target object is stopped. In the present embodiment, the motion information includes hand motions (e.g., V-shaped gestures, OK gestures, arm swing motions, etc.), head motions (head nodding motions, head swinging motions, etc.), leg motions, etc. In order to describe the technical solution of the present invention in more detail, in this embodiment, taking a hand gesture as an example, the technical solution of the present invention is described in detail: assume that there are two target objects, a and B, within the shooting area. And at a certain moment, acquiring the gesture of swinging the V character of the A, continuing to track and shoot the A, and stopping shooting the B. The embodiment can quickly and automatically switch from the track shooting of a plurality of target objects to the track shooting of one target object through the capture of the motion information and the analysis of the motion information, thereby enabling the track shooting to be more intelligent. It should be noted that, the present embodiment may store a plurality of target objects currently being tracked and shot, and when receiving the motion information (for example, an OK gesture) of a target object, may also resume tracking and shooting of a plurality of target objects from tracking and shooting of one target object. Specifically, on the basis of the above embodiment, in other embodiments, the tracking shooting a and B is resumed when the gesture of swinging the OK word by the camera a is acquired.
The shooting terminal 1 and the shooting auxiliary carrier 2 in the embodiment are small in size and light in weight, so that the shooting terminal is not limited by a place and is easy to carry, and the application place range of tracking shooting is expanded. In addition, after the shooting terminal 1 is in communication connection with the shooting auxiliary carrier 2, tracking shooting is automatically performed, so that the automatic performance of tracking shooting is improved.
The second tracking shooting method embodiment:
as an improvement to the first embodiment, referring to fig. 5, an embodiment of the present invention provides a tracking shooting method, which is characterized in that: the method comprises the following steps: in step S10, the photographing terminal 1 is detachably connected to the photographing auxiliary carrier 2 and establishes a communication connection with the photographing auxiliary carrier 2.

In step S11, a tracking shooting command input by the user is received, and the tracking shooting command is executed to enter a tracking shooting mode. The step S11 is similar to the step S2, and therefore, will not be described herein.
In step S12, a shooting operation is performed in the tracking shooting mode to obtain tracking video information. The step S12 is similar to the step S3, and therefore, will not be described herein.
Step S13, detecting whether the environment in which the mobile terminal is located has a wireless network. When the environment in which the mobile terminal is located does not have a wireless network, step S14 is performed. When the environment in which the mobile terminal is located has a wireless network, step S50 is performed.
In this embodiment, the shooting terminal may further detect whether a network is available, specifically, whether a wireless network where the shooting terminal is located is available or whether a mobile communication network of the shooting terminal is available.
