Each step in fig. 2 will be described in detail below.
Step S210, obtaining device parameters of a real shooting device in a real scene, and determining a motion range of a virtual shooting device corresponding to the real shooting device in a virtual scene based on the device parameters of the real shooting device.
The real scene refers to a real existing scene, and may be a green scene specially constructed for shooting, so as to facilitate post-keying synthesis, where the real scene may include a shot object, such as a live broadcaster, an actor, a prop, and other real objects.
The real shooting device refers to shooting auxiliary devices of the real shooting device, such as a motor-driven sliding rail, a motor-driven holder and the like, which can be used for shooting, and the devices are installed in a real scene, and the specific installation position and angle are determined by the shooting target position in the real scene to be shot.
The electric slide rail is used for shooting by the entity camera, real shooting equipment is fixed on the electric slide rail, and the movement of the real shooting equipment can be controlled through an electronic program. The electric pan-tilt is a supporting device for installing and fixing the entity camera, and the camera can be controlled to rotate through a control signal of the controller.
The device parameters of the real photographing device refer to parameters that can be used to distinguish real photographing devices having different functions, and may be related parameters such as the type, brand, and model of the photographing device.
The virtual scene may be a virtual scene previously created by the virtual engine, and may include elements such as scenes, characters, lights, and the like, for example, scenes such as a virtual live room, a virtual studio, and the like.
The virtual shooting equipment is used for simulating real shooting equipment and shooting a virtual scene to acquire a virtual picture in the virtual scene. The movement range of the virtual photographing apparatus refers to a movable range of the virtual photographing apparatus in the virtual scene. For example, when the real shooting device is determined to be a transverse electric slide rail according to the device parameters of the real shooting device, the transverse movable distance of the transverse electric slide rail is the movement range of the virtual shooting device.
It should be noted that, before executing step S210, the user may perform wired physical connection or wireless physical connection between the real shooting device and the execution terminal device in advance, so that the device terminal and the real shooting device can perform communication subsequently.
In an optional implementation manner, after the user performs wired physical connection or wireless physical connection between the real shooting device and the terminal device, the terminal device may call the device driver library according to the device parameters of the real shooting device to connect to the real shooting device, so that the terminal device can communicate with the real shooting device and control the real shooting device.
In the process, the communicable connection is established between the terminal device and the real shooting device by calling the driver so as to drive the control system of the real shooting device, so that the terminal device can control the real shooting device installed on the real shooting device.
In an optional implementation manner, acquiring device parameters of a real shooting device in a real scene includes: and responding to the equipment parameter input operation of the real shooting equipment in the real scene, and acquiring the equipment parameters of the real shooting equipment.
The device parameter entry operation may be an operation of configuring device parameters such as a brand, a type, and a model of the real shooting device in the terminal device.
In the process, the device parameters of the corresponding real shooting device are obtained by reading the recorded device parameters, so that on one hand, a parameter basis is provided for determining the motion range of the virtual shooting device, and on the other hand, a device connection object is provided for the terminal device, so that the terminal device and the corresponding real shooting device are in communication connection.
It should be noted that, it is necessary to ensure that the recorded device parameters are consistent with the device parameters of the real shooting device that performs physical connection, so as to prevent the terminal device from being unable to identify the connected real shooting device, thereby affecting the normal operation of shooting.
In an optional implementation manner, determining a motion range of a virtual shooting device corresponding to a real shooting device in a virtual scene based on device parameters of the real shooting device may be implemented by the steps shown in fig. 3, which specifically include the following steps S310 to S320:
step S310, determining the motion range of the real shooting equipment based on the equipment parameters of the real shooting equipment;
step S320, mapping the motion range of the real shooting device to the virtual scene according to the spatial mapping relationship between the virtual scene and the real scene, so as to determine the motion range of the virtual shooting device.
The movement range of the real photographing apparatus refers to a spatial range in which a physical camera mounted on the real photographing apparatus can move. For example, when the real photographing apparatus is a transverse motorized slide rail, the movement range thereof may be the maximum transverse movable distance of the physical camera mounted on the transverse motorized slide rail.
The spatial mapping relationship between the virtual scene and the real scene refers to a spatial dimension proportional relationship between the virtual scene and the real scene. When the virtual scene is modeled relative to the real scene in a 1:1 ratio, then the range of motion of the real camera can be taken as the range of motion of the virtual camera. When the virtual scene is not modeled relative to the real scene according to the 1:1 ratio, the motion range of the real shooting equipment needs to be converted according to the scene ratio to obtain the motion range of the virtual shooting equipment.
In the process, the movement range of the virtual shooting equipment is determined through the movement range of the real shooting equipment, so that the movement ranges of the real shooting equipment and the virtual shooting equipment correspond to each other, and the shooting angles of the real shooting equipment and the virtual shooting equipment can be ensured to be consistent in the subsequent shooting process.
Step S220, responding to the control operation of the virtual shooting equipment in the motion range of the virtual shooting equipment, controlling the virtual shooting equipment to carry out motion shooting, and acquiring the motion track of the virtual shooting equipment;
the control operation for the virtual photographing apparatus may be an operation of performing a drag movement for the corresponding virtual camera in the terminal apparatus. Further, the control operation for the virtual photographing apparatus may also be a drag operation for a virtual scene picture photographed by the virtual photographing apparatus. When the virtual shooting device shoots in a virtual scene, the terminal device can record the motion track of the virtual shooting device in real time.
The above process provides a reference trajectory for performing a synchronous motion for the real photographing apparatus by acquiring the motion trajectory of the virtual photographing apparatus.
In an alternative embodiment, the above-mentioned controlling the virtual shooting device to perform motion shooting and acquiring the motion track of the virtual shooting device in response to the control operation on the virtual shooting device within the motion range of the virtual shooting device may be implemented by steps shown in fig. 4, and specifically includes the following steps S410 to S420:
step S410, determining a target mirror moving arrangement form of the virtual shooting equipment from a preset mirror moving library according to the motion range of the virtual shooting equipment;
and step S420, in response to the mirror movement triggering operation in the target mirror movement arrangement form, controlling the virtual shooting equipment to carry out movement shooting, and acquiring the movement track of the virtual shooting equipment.
The preset mirror library refers to a mirror set containing a plurality of mirror arrangement forms, and is configured in the terminal device in advance for calling. The target moving mirror arrangement form refers to a virtual moving mirror arrangement form which conforms to the movement range of the virtual shooting device. The mirror operation triggering operation may be a triggering operation performed on a plurality of mirror operation arrangement forms configured in the corresponding type of virtual mirror operation grouping, and may be triggered by a user at a terminal device, and after the triggering operation is performed, the virtual shooting device may move according to the triggered mirror operation arrangement form.
The moving mirror marshalling which accords with the motion range of the virtual shooting equipment is selected from the preset moving mirror library, so that a moving strategy can be provided for the moving mirror of the virtual shooting equipment in a virtual scene, and the convenience of controlling the virtual shooting equipment is improved.
The real shooting devices of different types and/or the device combinations of the real shooting devices of different types can also correspond to different virtual mirror marshalling, each mirror marshalling is configured with at least one mirror marshalling form for a user to select and trigger, and the triggerable target mirror marshalling form is determined by judging the mirror marshalling corresponding to the real shooting devices. Different types of real shooting devices may, for example: the horizontal electronic slide rail, the horizontal electronic slide rail of arc, ordinary electronic cloud platform, triaxial electronic cloud platform etc.. Device combinations of different types of real shooting devices can be, for example: horizontal electronic slide rail + ordinary electronic cloud platform, horizontal electronic slide rail + triaxial electronic cloud platform etc.. As shown in table 1 below, the types of common real shooting devices and the corresponding virtual mirror grouping list are given.
TABLE 1
In addition, data calling can be performed on the software development toolkits of the types of the real shooting devices in advance, and compatible processing is performed, so that when the real shooting devices of the corresponding types are accessed, the terminal device can normally operate.
And step S230, determining to-be-moved data of the real shooting equipment according to the movement track of the virtual shooting equipment, and controlling the real shooting equipment to carry out movement shooting in a real scene based on the to-be-moved data.
The data to be moved of the real photographing apparatus may include data of a direction, a speed, a distance, and a rotation angle in which the real photographing apparatus is to be moved.
In an optional implementation manner, determining data to be moved of the real shooting device according to the motion track of the virtual shooting device includes: and mapping the motion trail of the virtual shooting equipment to the real scene according to the space mapping relation between the virtual scene and the real scene so as to determine the data to be moved of the real shooting equipment.
For example, when the real shooting device is a transverse electric slide rail and the moving track of the virtual shooting device is the X-axis transverse movement, the moving distance of the virtual shooting device in the positive direction of the X-axis is converted to obtain the transverse moving distance of the transverse electric slide rail along the positive direction of the X-axis.
