Problems solved by technology

In the existing tracking shooting methods, 2D models are usually used for identification and analysis. When the target object rotates, the 3D object cannot be matched with the 2D model, so the tracking shooting of the object cannot be continued, resulting in interruption of shooting

Embodiment 1

[0044] figure 1 It is a schematic flow chart of the tracking and shooting method provided in Embodiment 1 of the present invention. The method can be executed by a tracking and shooting device or electronic equipment. The device or electronic device can be implemented by software and / or hardware. The device or electronic device can be Integrate in any smart device with network communication function. like figure 1 As shown, the tracking shooting method may include the following steps:

[0045] S101. When it is detected that the target object is transformed from the current object pose to the next object pose, calculate the pose parameters of the target object relative to the 3D model of the target object in the next object pose through the AR model.

[0046] In a specific embodiment of the present invention, when it is detected that the target object is transformed from the current object pose to the next object pose, the electronic device can use the AR model to calculate t...

Embodiment 2

[0053] figure 2 It is a schematic flowchart of the tracking and photographing method provided by Embodiment 2 of the present invention. like figure 2 As shown, the tracking shooting method may include the following steps:

[0054] S201. When it is detected that the target object is transformed from the current object pose to the next object pose, use the AR model to match the target object with the 3D model of the target object.

[0055]In a specific embodiment of the present invention, when it is detected that the target object is transformed from the current object pose to the next object pose, the electronic device can match the target object with the 3D model of the target object through the AR model. That is: when the target object rotates and causes the spatial distance or projection angle between the target object and its corresponding 3D model to change, the 3D model of the target object can still be used to lock the target object without causing the target to shoo...

Embodiment 3

[0066] image 3 It is a schematic flowchart of the tracking and photographing method provided by Embodiment 3 of the present invention. like image 3 As shown, the tracking shooting method may include the following steps:

[0067] S301. When it is detected that the target object is transformed from the current object pose to the next object pose, use the AR model to match the target object with the 3D model of the target object.

[0068] In a specific embodiment of the present invention, when it is detected that the target object is transformed from the current object pose to the next object pose, the electronic device can match the target object with the 3D model of the target object through the AR model. That is: when the target object rotates and causes the spatial distance or projection angle between the target object and its corresponding 3D model to change, the 3D model of the target object can still be used to lock the target object without causing the target to shoot...

Abstract

An embodiment of the invention discloses a tracking shooting method and device, electronic equipment and a storage medium. The method comprises the steps: when it is detected that a target shooting object is converted from a current object pose to a next object pose, calculating pose parameters of the target shooting object on the next object pose relative to a 3D model of the target shooting object through an AR model; according to the pose parameter of the target shooting object relative to the 3D model on the next object pose and the pose parameter of the target shooting object relative tothe 3D model on the current object pose, calculating a change value of the pose parameter of the target shooting object on the next object pose relative to the pose parameter of the target shooting object on the current object pose; and according to the change value of the pose parameter of the target shooting object on the next object pose relative to the pose parameter of the target shooting object on the current object pose, controlling the shooting equipment to be converted from the current shooting pose to the next shooting pose, and controlling the shooting equipment to shoot the targetshooting object on the next shooting pose.

Description

technical field [0001] Embodiments of the present invention relate to the field of electronic technology, and in particular, to a method, device, electronic device, and storage medium for tracking and shooting. Background technique [0002] With the development of electronic technology, mobile terminals have become an indispensable necessity in people's lives, and the camera is one of the necessary configurations for most mobile terminals. People can use it to shoot people and scenery to record life. It is a very popular function. [0003] In many application scenarios, it is necessary to track and shoot an object, that is, to shoot the object as the target object moves. During the moving process of the object, if you want to intelligently follow and shoot the object, you must solve the problem of intelligent model matching and follow-up control under different viewing angles. In the existing tracking and shooting methods, the 2D model is usually used for identification an...
