Abstract

The present application provides a method for invoking a panoramic picture, and a panoramic camera system. The method includes steps of: collecting multiple camera pictures; unfolding and stitching the collected multiple camera pictures to obtain the panoramic picture; mapping the panoramic picture into a target sphere model to obtain a panoramic sphere picture; and creating a virtual camera, where a third-party application is enabled to directly invoke the virtual camera to obtain the panoramic picture. The present application can facilitate the third-party application to directly invoke the panoramic picture in the panoramic camera system.

Claims (53)

creating a virtual camera that is configured to replace a physical camera of the panoramic camera platform, and enabling a third-party application to directly invoke the virtual camera to obtain the panoramic picture and/or the panoramic sphere picture.

2 . The method for invoking the panoramic picture according to claim 1 , wherein the panoramic sphere picture in the display mode corresponding to the parameter of the virtual video camera comprises a panoramic sphere picture in an immersive mode, or a panoramic sphere picture in an asteroid mode.

3 . The method for invoking the panoramic picture according to claim 2 , wherein the panoramic camera platform comprises an inertial measurement unit, and said unfolding and stitching the collected multiple camera pictures to obtain the panoramic picture further comprises:

obtaining data from the inertial measurement unit;

obtaining by calculation, a current posture of the panoramic camera platform according to the data of the inertial measurement unit; and

correcting the panoramic picture according to the current posture of the panoramic camera platform.

4 . The method for invoking the panoramic picture according to claim 1 , wherein said unfolding and stitching the collected multiple camera pictures to obtain the panoramic picture further comprises:

detecting and recognizing a target object in the panoramic picture; and

recognizing a position of the target object in the panoramic picture.

5 . The method for invoking the panoramic picture according to claim 2 , wherein said unfolding and stitching the collected multiple camera pictures to obtain the panoramic picture further comprises:

detecting and recognizing a target object in the panoramic picture; and

recognizing a position of the target object in the panoramic picture.

6 . The method for invoking the panoramic picture according to claim 3 , wherein said unfolding and stitching the collected multiple camera pictures to obtain the panoramic picture further comprises:

detecting and recognizing a target object in the panoramic picture; and

recognizing a position of the target object in the panoramic picture.

7 . The method for invoking the panoramic picture according to claim 4 , wherein said creating the virtual video camera that is configured to observe the panoramic sphere picture and obtaining, by setting the parameter of the virtual video camera, the panoramic sphere picture in the display mode corresponding to the parameter of the virtual video camera further comprises:

adjusting, according to the position of the target object in the panoramic picture, the parameter of the virtual video camera, to enable the target object to be always located in a middle of the panoramic sphere picture.

8 . The method for invoking the panoramic picture according to claim 5 , wherein said creating the virtual video camera that is configured to observe the panoramic sphere picture and obtaining, by setting the parameter of the virtual video camera, the panoramic sphere picture in the display mode corresponding to the parameter of the virtual video camera further comprises:

adjusting, according to the position of the target object in the panoramic picture, the parameter of the virtual video camera, to enable the target object to be always located in a middle of the panoramic sphere picture.

9 . The method for invoking the panoramic picture according to claim 6 , wherein said creating the virtual video camera that is configured to observe the panoramic sphere picture and obtaining, by setting the parameter of the virtual video camera, the panoramic sphere picture in the display mode corresponding to the parameter of the virtual video camera further comprises:

adjusting, according to the position of the target object in the panoramic picture, the parameter of the virtual video camera, to enable the target object to be always located in a middle of the panoramic sphere picture.

10 . A panoramic camera system, installed with a third-party application, and comprising:

a collection module, configured to collect multiple camera pictures of the panoramic camera system;

a processing module, configured to unfold and stitch collected multiple camera pictures to obtain a panoramic picture;

a mapping module, configured to map the panoramic picture into a target sphere model to obtain a panoramic sphere picture;

a virtual video camera module, configured to create a virtual video camera, wherein the virtual video camera is configured to observe the panoramic sphere picture in the target sphere model, and is enabled to obtain by setting a parameter of the virtual video camera, the panoramic sphere picture in a display mode corresponding to the parameter of the virtual video camera; and

an invoking module, wherein the third-party application is enabled to directly invoke, by means of the invoking module, the panoramic picture obtained by the processing module and/or the panoramic sphere picture obtained by the virtual video camera module.

11 . The panoramic camera system according to claim 10 , wherein the third-party application is provided with a layer of user interaction interface, and the user interaction interface is configured to control the parameter of the virtual video camera in the virtual video camera module, to enable the third-party application to obtain panoramic sphere pictures in different modes.

12 . The panoramic camera system according to claim 11 , wherein the invoking module of the panoramic camera system comprises a virtual camera, and the third-party application is configured to invoke the virtual camera to obtain the panoramic picture and/or the panoramic sphere picture.

13 . A non-transitory computer-readable storage medium, wherein a computer program is stored on the non-transitory computer-readable storage medium, and wherein when the computer program is executed by a processor, steps of the method for invoking the panoramic picture according to claim 1 are implemented.

14 . The non-transitory computer-readable storage medium according to claim 13 , wherein the panoramic sphere picture in the display mode corresponding to the parameter of the virtual video camera comprises a panoramic sphere picture in an immersive mode, or a panoramic sphere picture in an asteroid mode.
