Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. The embodiments of this application are described in detail below in conjunction with the drawings.

[0059] The following is combined with Figures 1 to 5 This application is described in further detail.

[0060] The first aspect of the present application provides a method for realizing multi-angle recording based on multiple cameras, such as Figure 1 As shown, the following steps are included:

[0061] Arrange multiple cameras on the bird feeder to achieve 360° video acquisition;

[0062] Divide the 3D space area based on the position of each camera;

[0063] Determine the flying track of the target in each camera when it flies into different 3D space areas, and determine the flying track of the target in each camera when it flies out of different 3D space areas;

[0064] Video clips are edited according to the target's flying-in trajectory and flying-out trajectory to generate 3D surround video clips.

[0065] The method of realizing multi-angle recording based on multiple cameras in the present application first arranges multiple cameras on the bird feeder to realize 360° video acquisition, specifically including: constructing a spherical coordinate system, arranging three cameras A, B, and C on the bird feeder, wherein the three cameras are respectively used as a vertex of a spherical regular triangle, and the video acquisition angles of the three cameras cover a 360° picture. In this embodiment, if Figure 2 As shown, three cameras are used to construct different perspectives, which are arranged at the top C, the lower left A, and the lower right B respectively, for multi-camera preview and recording. The three cameras are designed in a spherical equilateral triangle structure at a certain angle. The three cameras can cover 360° of the picture and construct a 3D surround perspective.

[0066] The method of realizing multi-angle recording based on multiple cameras in this application, and then dividing the 3D space area based on the position of each camera, such as Figure 3 As shown, specifically, the three vertices of the spherical regular triangle formed by the three cameras A, B, and C correspond to the a side, the b side, and the c side respectively, where:

[0067] The b and c edges extend toward A to obtain the SA region;

[0068] The a and c sides extend toward B to obtain the SB region;

[0069] The a and b sides are extended toward C to obtain the SC region;

[0070] The a and b sides extend away from C to obtain the S.AB region;

[0071] The b and c edges extend away from A to obtain the S.BC region;

[0072] The a and c edges extend away from B to obtain the S.AC region.

[0073] The method of realizing multi-angle recording based on multiple cameras of the present application divides the 3D space area into 6 surfaces to obtain SA, SB, SC, S.AB, S.BC, and S.AC areas, wherein the S.ABC area surrounded by the a side, b side, and c side is the physical product structure. There is no possibility of a bird or pet flying from this direction, and it is not calculated within the subsequent possibility range.

[0074] The method of realizing multi-angle recording based on multiple cameras of the present application analyzes the order of appearance of bird pets in the three cameras after completing the spatial division. Bird pets must fly in and out of the above six areas, and there will be an order of entering and exiting the camera screen when flying in different areas. For example, if the target flies in from the S.AC area, the camera corresponding to B should be the first camera to capture the target screen. Secondly, according to whether the target is from the upper point C or the lower point A in the S.AC space area, it can be judged whether the target appears first in the camera screen corresponding to A or the camera screen corresponding to C. According to the blind spot principle, the camera that appears the latest to the target must be relatively closer to it. In addition, according to the rules of reverse pictures and sequences, the order of flying out is opposite to that of flying in. The camera that appears first when flying in must be the camera that disappears the latest when flying out. Corresponding to each SA, SB, SC, S.AB, S.BC, and S.AC area, flying out shows a certain regularity.

[0075] In a preferred embodiment of the present application, the flying traces of the target flying into each camera from different 3D space areas are obtained through the above analysis, including:

[0076] If the target flies in from the SA area and the flying position is facing the SA area, the order of the targets appearing in the three cameras is B=C>A; if the target flies in from the SA area and the flying position is close to the S.AC area, the order of the targets appearing in the three cameras is B>C>A; if the target flies in from the SA area and the flying position is close to the S.AB area, the order of the targets appearing in the three cameras is C>B>A;

[0082] In this embodiment, the flying tracks of the target from different 3D space areas in each camera are obtained through the above analysis, including:

[0083] If the target flies out of the SA area and the flying position is facing the SA area, the order in which the target disappears from the three cameras is A>B=C; if the target flies out of the SA area and the flying position is close to the S.AC area, the order in which the target disappears from the three cameras is A>C>B; if the target flies out of the SA area and the flying position is close to the S.AB area, the order in which the target disappears from the three cameras is A>B>C;

[0087] If the target flies out of the S.BC area and the flying position is facing the S.BC area, the order in which the target disappears from the three cameras is B=C>A; if the target flies out of the S.BC area and the flying position is close to the SB area, the order in which the target disappears from the three cameras is B>C>A; if the target flies out of the S. BC area and the flying position is close to the SC area, the order in which the target disappears from the three cameras is C>B>A;

[0088] If the target flies out of the S.AC area and the flying position is facing the S.AC area, the order in which the target disappears from the three cameras is A=C>B; if the target flies out of the S.AC area and the flying position is close to the SC area, the order in which the target disappears from the three cameras is C>A>B; if the target flies out of the S.AC area and the flying position is close to the SA area, the order in which the target disappears from the three cameras is A>C>B.

[0089] The method of realizing multi-angle recording based on multiple cameras of the present application performs video editing according to the target's flying-in trajectory and flying-out trajectory to generate 3D surround video clips, including:

[0090] Select the first video clip captured by the Camera where the target first appears from the target's flying trajectory;

[0091] Select the second video clips captured by Cameras A, B, and C at the same time;

[0092] Select the third video clip captured by the Camera where the target disappears last from the target's flight path;

[0093] The first video segment, the second video segment and the third video segment are spliced ​​together to obtain a 3D surround video segment.

[0094] The method of realizing multi-angle recording based on multiple cameras of the present application, after obtaining the target's flying-in and flying-out tracks, performs video editing to generate 3D surround video clips. The three pictures captured by the three cameras corresponding to A, B, and C at the same time can select the camera video of the target in the picture close to the center of the camera. For example, if it flies in from S.AC, the video captured by the camera corresponding to B is selected first. If it is close to the center of the camera picture corresponding to A, B, and C at a certain moment, the angles captured by three different cameras corresponding to A, B, and C can be selected for multi-angle observation of the target 3D full picture in the central area, and slow motion can also be used. For example, assuming that the target flies in from the S.AC area and flies out from the S.BC area, then along with the flight path of the target, the video captured by the camera corresponding to B, the videos captured by the three cameras corresponding to A, B, and C, and the video captured by the camera corresponding to A are edited in turn to form a complete 360° stereo surround video clip. The videos captured by the three cameras in the second video clip can be played synchronously in different windows. The principles and logics of other flying in and out are similar and will not be repeated one by one.

[0095] It is understandable that users can share the finished film directly on social media after getting it.
