Wherein, the relative position includes the distance of electronic equipment and wearing equipment to and the rotation angle of electronic equipment for wearing equipment, this rotation angle can be euler rotation angle.

In another possible implementation, the relative position of the electronic device and the wearable device is determined by the electronic device. Specifically, as shown in fig. 5, a gyroscope is disposed on the electronic device, and the gyroscope can record angle information of the electronic device during rotation. The method comprises the steps of firstly setting an initial position of the electronic equipment, calculating a rotation angle of the electronic equipment according to angle information corresponding to the electronic equipment at the initial position and angle information corresponding to the electronic equipment at the current position, and then combining a preset distance between the electronic equipment and the wearable equipment to obtain the relative position of the electronic equipment and the wearable equipment. For example, the initial position of the electronic device may be set to: the distance from the front of the wearable device is a position at a fixed distance, for example, a position at a distance of 0.8 meter from the front of the wearable device. In the process that the electronic equipment rotates by taking the initial position as a center, the distance between the electronic equipment and the wearable equipment is unchanged, the electronic equipment calculates the rotation angle of the electronic equipment according to the angle information recorded by the gyroscope, the electronic equipment calculates the rotation angle of the electronic equipment relative to the wearable equipment according to the angle of the initial position relative to the wearable equipment and the rotation angle of the electronic equipment, and then the relative position of the electronic equipment and the wearable equipment is obtained by combining the fixed distance between the electronic equipment and the wearable equipment.

S102: and calculating the position information of the electronic equipment in the virtual space according to the relative position of the electronic equipment and the wearable equipment.

In one possible implementation, the wearable device performs position calibration before use, specifically, establishes a coordinate system of a virtual space so that the coordinate system of the virtual space coincides with a coordinate system of a pre-established real space. After carrying out position calibration, if the user is stationary, the positional information of wearing equipment in virtual space is unanimous with the positional information of wearing equipment in real space, and wherein, wearing equipment can calculate the positional information of wearing equipment in real space according to the distance between the initial point of wearing equipment and real space's coordinate system to regard the positional information of wearing equipment in real space as the positional information of wearing equipment in virtual space.

In another possible implementation, for example, for a VR glasses with 6 degrees of freedom (DOF), the VR glasses are position-calibrated before use to obtain a mapping relationship between a coordinate system of a virtual space and a coordinate system of a real space. Specifically, after the user wears the VR glasses, a depth camera on the VR glasses scans a reference object in a real space, for example, a static object such as a ground, a wall, a table, a chair, and the like, to obtain a depth image of the reference object, and a relative position between the reference object and the VR glasses is calculated according to the depth image of the reference object. The position information of the VR glasses in the virtual space is obtained according to a pre-established coordinate system of the virtual space, for example, if the pre-established coordinate system of the virtual space uses the center of the VR glasses as the origin of coordinates, the position of the VR glasses in the virtual space is the origin of coordinates. Then obtaining the position information of the reference object in the virtual space according to the relative position of the reference object and the VR glasses and the position information of the VR glasses in the virtual space; and obtaining the position information of the reference object in the real space according to the pre-established coordinate system of the real space and the depth image of the reference object, and obtaining the mapping relation between the coordinate system of the virtual space and the coordinate system of the real space according to the position information of the reference object in the virtual space and the position information of the reference object in the real space. After the position calibration is performed, if the user is stationary, the electronic device can calculate the position information of the electronic device in the virtual space according to the position information of the VR glasses in the virtual space and the relative position of the electronic device and the VR glasses. If the user walks in the real space, the distance between the VR glasses and the reference object changes, the depth camera on the VR glasses shoots the depth image of the reference object again to obtain the relative position of the reference object and the VR glasses, and then the position information of the VR glasses in the real space is obtained according to the position information of the reference object in the real space. And obtaining the position information of the VR glasses in the virtual space according to the position information of the VR glasses in the real space and the mapping relation between the coordinate system of the virtual space and the coordinate system of the real space, and obtaining the position information of the electronic equipment in the virtual space according to the relative position of the electronic equipment and the VR glasses.

In one possible implementation, the position information of the camera 193 on the electronic device in the virtual space can be calculated according to the position information of the electronic device in the virtual space and the position of the camera on the electronic device. For example, the electronic device is a mobile phone, the mobile phone is provided with a front camera and a rear camera, when a user opens the front camera, the position information of the front camera in the virtual space is calculated, and when the user opens the rear camera, the position information of the rear camera in the virtual space is calculated.

S103: acquiring an image shot by a virtual camera in the virtual space, wherein the position information of the virtual camera in the virtual space is the same as the position information of the electronic equipment in the virtual space.

Specifically, the electronic device sends the position information of the electronic device in the virtual space to the wearable device, and the wearable device takes the position information of the electronic device in the virtual space as the position information of the virtual camera in the virtual space, that is, the shooting angle of the electronic device in the virtual space is the same as the shooting angle of the virtual camera in the virtual space. In other feasible implementation manners, the electronic device sends the position information of the camera used by the electronic device currently in the virtual space to the wearable device, and the wearable device uses the position information of the camera used by the electronic device currently in the virtual space as the position information of the virtual camera in the virtual space. After the position information of the virtual camera in the virtual space is determined, the wearable device sends the image shot by the virtual camera to the electronic device, namely, the image of the virtual space under the current view angle of the virtual camera, and meanwhile, the user can see the image shot by the virtual camera on the screen of the 3D mobile phone model of the virtual space through the wearable device. When the angle of the electronic equipment is changed, the angle of the virtual camera is correspondingly adjusted to obtain the image shot by the virtual camera with the angle of view adjusted, and the wearable equipment sends the image shot by the virtual camera with the angle of view adjusted to the electronic equipment.

Wherein the target object is a human object or a real scene.

S105: and superposing the image of the target object and the image shot by the virtual camera, and outputting the superposed image.

Specifically, the electronic device removes the background of the image of the target object, for example, an image segmentation algorithm may be used to remove the background of the image of the target object, take the image of the target object from which the background is removed as the foreground, take the image captured by the virtual camera as the background, superimpose the foreground and the background, and output the superimposed image. Specifically, the electronic device sends the superposed image to the wearable device, and the user can see the superposed image on a screen of the 3D mobile phone model in the virtual space through the wearable device. Further, when the electronic device acquires a shooting instruction, the superposed image can be stored, when the wearing device is worn by a user, the electronic device sends the stored superposed image to the wearing device, and the user can browse the stored image on the 3D mobile phone model in the virtual space, namely the image synthesized by the target object and the virtual space.

The image of the target object and the image captured by the virtual camera may be two images captured synchronously or two images captured asynchronously. In one application scenario, the image of the target object and the image captured by the virtual camera are not captured simultaneously, for example, as shown in fig. 6 (a), after receiving the image captured by the virtual camera, the electronic device imports the image of the target object captured in advance according to the user operation, performs preprocessing operations such as moving or zooming on the image of the target object, removes the background of the preprocessed image of the target object, uses the image of the target object as the foreground, and uses the image captured by the virtual camera as the background, thereby obtaining the superimposed image as shown in fig. 6 (B). In another application scenario, the image of the target object and the image captured by the virtual camera are captured synchronously, for example, as shown in fig. 7, when the electronic device receives the image captured by the virtual camera, the electronic device performs background removal processing on the image of the target object currently captured by the camera of the electronic device, uses the image of the target object with the background removed as a foreground, uses the image captured by the virtual camera as a background, obtains a superimposed image, and sends the superimposed image to the wearable device, so that the user can see the superimposed effect of the images of the virtual space and the target object through the wearable device, and can adjust the target object. After the user adjusts the target object, for example, the distance between the target object and the electronic device is adjusted, or the angle of the target object is adjusted, the electronic device superimposes the image of the adjusted target object with the image captured by the virtual camera again, and outputs the superimposed image.

Taking the electronic device as a mobile phone as an example, the image of the target object may be captured by a front camera of the mobile phone or a rear camera of the mobile phone. The scene of the image of the target object shot by the front-facing camera is generally a scene of self-shooting of the user, if the image of the target object, namely the self-shooting image and the image shot by the virtual camera are shot synchronously, the user needs to wear the wearable device to adjust the visual angle of the virtual camera, so that the self-shooting image in the superposed images is generally the image of the wearable device worn by the user as shown in fig. 8 (a), and the image of the target object, namely the self-shooting image, can be restored according to a preset three-dimensional image model to obtain the image without the wearable device as shown in fig. 8 (B). For example, images of the user head portrait at various visual angles are shot in advance, a three-dimensional image model of the user head portrait is constructed, when a user carries out self-shooting by using the shooting method, the user head portrait is restored by adopting a face shielding restoration algorithm according to the self-shooting image shot by the electronic equipment and the pre-constructed three-dimensional image model of the user head portrait, the restored user head portrait is overlapped with the image shot by the virtual camera, and the overlapped image is output.

In the above embodiment, the electronic device calculates the position information of the electronic device in the virtual space according to the relative position of the electronic device and the wearable device, adjusts the position information of the virtual camera in the virtual space to the position information of the electronic device in the virtual space, acquires the image captured by the virtual camera, and superimposes the image of the target object and the image captured by the virtual camera to obtain the superimposed image. Because the relative position of the electronic equipment and the wearable equipment is determined by the electronic equipment or the wearable equipment, the image of the virtual space and the superposed target object can be obtained only by the electronic equipment and the wearable equipment, so that VR shooting can be conveniently and quickly carried out.
