Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] like Figures 1-5 As shown, this embodiment provides a prop cannon 100 for virtual shooting, applied in virtual shooting. Virtual shooting is achieved through a virtual shooting system 200, specifically through a virtual camera, the movement of which is driven by the virtual cannon. This prop cannon 100 provides realistic rotation data to the virtual cannon in the virtual shooting system 200, ensuring more realistic and accurate movement of the virtual cannon, thereby guaranteeing the shooting effect of the virtual camera.

[0036] The prop cannon 100 used for virtual shooting includes a bracket 1, a connecting frame 2, a rotation detection component 4, and a controller 3. The bracket 1 includes a frame body 11, a gimbal 12, and a first rotating base 13. The first rotating base 13 is swayably mounted on the frame body 11, and the gimbal 12 is tilted on the first rotating base 13. The connecting frame 2 is mounted on the first rotating base 13. The rotation detection component 4 includes a pitch detection component 41 and a sway detection component 42. Both the pitch detection component 41 and the sway detection component 42 are mounted on the connecting frame 2. The pitch detection component 41 is used to detect the pitch angle of the gimbal 12, and the sway detection component 42 is used to detect the sway angle of the gimbal 12. The controller 3 can be connected to the pitch detection component 41 and the sway detection component 42 respectively. The rotation detection component 4 sends the actual tilt and pitch angles of the gimbal 12 to the controller 3. The controller 3 then sends the actual tilt and pitch angle data to the virtual shooting system 200. The virtual shooting system 200 uses the actual tilt and pitch angle data to control the tilt and pitch of the virtual cannon, thereby causing the virtual camera to tilt and pitch to complete multi-angle virtual shooting. The prop cannon 100 used for virtual shooting provides the virtual cannon with actual tilt and pitch angle data, ensuring that the movement of the virtual cannon is more realistic and accurate, thus guaranteeing the shooting effect of the virtual camera.

[0037] like Figure 1 As shown, the bracket 1 also includes a second rotating base 14, which is tiltable and can be mounted on the first rotating base 13. The gimbal 12 is mounted on the second rotating base 14.

[0038] Furthermore, the bracket 1 also includes a first rotating shaft 15, which is rotatably mounted on the frame body 11. The axis of the first rotating shaft 15 extends along the height direction, and a first rotating base 13 is mounted on the first rotating shaft 15. When the first rotating shaft 15 rotates, it causes the first rotating base 13 to swing, which in turn causes the second rotating base 14 and the gimbal 12 to swing.

[0039] Furthermore, the bracket 1 also includes a second rotating shaft 16, which is rotatably mounted on the first rotating base 13. The axis of the second rotating shaft 16 is perpendicular to the axis of the first rotating shaft 15, and the second rotating base 14 is mounted on the second rotating shaft 16. When the second rotating shaft 16 rotates, it causes the second rotating base 14 to pitch, which in turn causes the gimbal 12 to pitch.

[0040] Furthermore, the support 1 also includes a handle 17, which is mounted on the gimbal 12. The handle 17 can be manually gripped to apply force, thereby causing the first rotating shaft 15 and the second rotating shaft 16 to rotate, thus realizing the pitch and sway of the gimbal 12.

[0041] In this embodiment, the bracket 1 is a combination of a gimbal and a tripod. The specific model of the tripod can be a FILM100M100mm professional heavy-duty tripod, and the specific model of the gimbal can be a Sachtler Dutch Head.

[0042] Furthermore, the prop cannon 100 used for virtual shooting also includes a control box 9, which is mounted on the gimbal 12, and the controller 3 is located inside the control box 9. The pitch and sway of the gimbal 12 cause the control box 9 to pitch and sway as well.

[0043] Furthermore, the rotation detection component 4 also includes a pitch data interface 45, which is located on the control box 9 and connected to both the controller 3 and the pitch detection component 41. The actual pitch angle data of the gimbal 12 detected by the pitch detection component 41 is transmitted to the controller 3 through the pitch data interface 45.

[0044] Furthermore, the rotation detection component 4 also includes a swing data interface 46, which is located on the control box 9 and connected to both the controller 3 and the swing detection component 42. The actual swing angle data of the gimbal 12 detected by the swing detection component 42 is transmitted to the controller 3 through the swing data interface 46.

[0045] like Figure 1 and Figure 2 As shown, the prop cannon 100 used for virtual filming also includes an RF transmission module 7, which is located on the control box 9 and is connected to both the controller 3 and the virtual filming system 200. Information transmission between the controller 3 and the virtual filming system 200 is achieved through the RF transmission module 7.

[0046] Specifically, the virtual shooting system 200 is installed on a computer, and the computer is equipped with an RF receiving module 300. The information of the controller 3 is transmitted through the RF transmitting module 7, the RF receiving module 300 receives the above information and transmits it to the virtual shooting system 200, thereby controlling the movement of the virtual cannon, thereby driving the movement of the virtual camera, so as to perform virtual shooting.

[0047] Furthermore, the prop cannon 100 for virtual shooting also includes a cannon arm adjustment component 5. The cannon arm adjustment component 5 includes a cannon arm length rocker arm 51, which is mounted on the control box 9 and connected to the controller 3. The length of the virtual cannon's arm is adjusted by pressing the cannon arm length rocker arm 51 forward or backward. It should be noted that the prop cannon 100 for virtual shooting does not have a physical cannon arm; the length of the virtual cannon's arm can be set using the cannon arm length rocker arm 51. For example, pressing the cannon arm length rocker arm 51 forward increases the length of the cannon arm; pressing it backward shortens the length of the cannon arm.

[0048] Furthermore, the gun arm adjustment assembly 5 also includes a gun arm length scaling knob 52, which is located on the control box 9 and connected to the controller 3 to scale the gun arm length. After the initial gun arm length of the virtual gun is set by the gun arm length joystick 51, the gun arm length scaling factor is set by rotating the gun arm length scaling knob 52 to obtain the final gun arm length. When the gun arm length scaling factor is 1, the initial gun arm length set by the gun arm length joystick 51 is equal to the final gun arm length.

[0049] Furthermore, the gun arm adjustment component 5 also includes an extreme value setting component 53, which is located on the control box 9 and connected to the controller 3. The extreme value setting component 53 sets a preset length range for the virtual gun's gun arm length. If the input virtual gun's gun arm length is outside the preset range, it is truncated, alerting the operator that the entered virtual gun's gun arm length value is incorrect and needs to be re-entered.

[0050] Furthermore, the maximum / minimum setting component 53 includes a maximum value setting knob 531, which is located on the control box 9 and connected to the controller 3. Rotating the maximum value setting knob 531 sets the maximum value of the virtual cannon's arm length; the virtual cannon's arm length cannot exceed the set maximum value.

[0051] Furthermore, the maximum / minimum setting component 53 also includes a maximum value cancellation knob 532, which is located on the control box 9 and connected to the controller 3. Rotating the maximum value cancellation knob 532 restores the maximum value of the virtual cannon's arm length to its default value. In this embodiment, the default value of the maximum value of the virtual cannon's arm length is 3000mm.

[0052] Furthermore, the maximum / minimum setting component 53 also includes a minimum setting knob 533, which is located on the control box 9 and connected to the controller 3. Rotating the minimum setting knob 533 sets the minimum length of the virtual cannon's arm; the length of the virtual cannon's arm cannot be less than the set minimum value.

[0053] Furthermore, the maximum / minimum setting component 53 also includes a minimum value cancellation knob 534, which is located on the control box 9 and connected to the controller 3. Rotating the minimum value cancellation knob 534 restores the minimum value of the virtual cannon's arm length to its default value. In this embodiment, the default value of the minimum virtual cannon arm length is 0mm.

[0054] Furthermore, the prop cannon 100 used for virtual shooting also includes a display module 6, which is located on the control box 9 and connected to the controller 3.

[0055] Specifically, display module 6 can be an LED screen, which can display the company logo, the arm length information of the virtual cannon, and rotation information. The arm length information of the virtual cannon includes the initial arm length of the virtual cannon set by the arm length joystick 51, the arm length scaling factor set by the arm length scaling knob 52, the maximum arm length of the virtual cannon set by the maximum value setting knob 531, and the minimum arm length of the virtual cannon set by the minimum value setting knob 533. The rotation information of the virtual cannon includes the pitch angle detected by the pitch detection element 41 and the yaw angle detected by the yaw detection element 42.

[0056] Furthermore, the prop cannon 100 used for virtual shooting also includes a restart button 10, which is located on the control box 9 and connected to the controller 3. When the controller 3 freezes or experiences other abnormal operation, pressing the restart button 10 will restart the controller 3, equivalent to a power-off and power-back operation. The arm length and rotation information of the virtual cannon will be restored to their default values. This provides a certain degree of protection for the controller 3, extends its service life, and ensures the accuracy of virtual shooting.

[0057] Furthermore, the prop cannon 100 used for virtual shooting also includes a zeroing button 01, which is located on the control box 9 and connected to the controller 3. Pressing the zeroing button 01 resets the accumulated counts of the pitch detector 41 and the yaw detector 42 to zero.

[0058] Furthermore, the prop cannon 100 used for virtual shooting also includes a power supply component 8, which includes a power module 81 and a power plug 82. The power plug 82 is located on the control box 9 and connected to the controller 3. The power plug 82 is used to connect the power module 81 to supply power to the controller 3.

[0059] like Figure 2 As shown, the virtual shooting system 200 can be a virtual engine, specifically Unreal Engine. The virtual engine is further developed to fully utilize the virtual camera function provided by the virtual engine, combined with the real rotation data captured by the prop cannon 100 used for virtual shooting, and reflected on the virtual cannon to obtain the motion trajectory of the virtual camera, so as to shoot virtual scenes and virtual characters from multiple angles.

[0060] like Figure 1 , Figure 3 and Figure 4As shown, the connecting frame 2 includes a locking ring 21, which can be locked onto the first rotating base 13. The pitch detection element 41 and the yaw detection element 42 are both connected to the locking ring 21.

[0061] Furthermore, the locking ring 21 includes a fitting portion 211 and a locking portion 212. The fitting portion 211 has an opening 213, and the locking portion 212 is disposed on the opening 213. The fitting portion 211 can be fitted onto the first rotating seat 13, and the locking portion 212 can lock the fitting portion 211 onto the first rotating seat 13. The rotation of the first rotating seat 13 drives the connecting frame 2, the pitch detection element 41, and the yaw detection element 42 to rotate.

[0062] Specifically, there are two locking parts 212, which are respectively located on both sides of the opening 213. Each locking part 212 has a locking hole, and the fastener is connected to the locking hole on the two locking parts 212 to lock the sleeve part 211 onto the first rotating base 13.

[0063] Furthermore, the connecting frame 2 also includes a first mounting part 22, which is disposed on the outer side wall of the sleeve part 211, and the swing detection element 42 is mounted on the first mounting part 22.

[0064] Specifically, both the yaw detection element 42 and the pitch detection element 41 can be encoders, and the specific model of both encoders can be Omron E6B2-CWZ3E. When the encoder's code disk rotates, the encoder's light source will output two pulse signals that are 90° out of phase. The pulse signals detect the number of rotations of the code disk and transmit the data to the controller 3. The controller 3 obtains the rotation angle (pitch angle and yaw angle) based on the number of rotations of the code disk.

[0065] Furthermore, the rotating detection assembly 4 also includes a detection wheel 44. The detection wheel 44 and the swing detection element 42 are both mounted on the first mounting part 22, and the detection wheel 44 and the swing detection element 42 are coaxially connected. The detection wheel 44 is in contact with the first rotating base 13.

[0066] Specifically, the detection wheel 44 is coaxially connected to the encoder that detects the swing angle, so as to drive the code disk of the encoder that detects the swing angle to rotate. The manual operation handle 17 drives the first rotating shaft 15 to rotate, which in turn drives the first rotating base 13 to swing. The first rotating base 13 drives the detection wheel 44 to swing, and the detection wheel 44 drives the code disk of the encoder that detects the swing angle to rotate, so as to detect the swing angle of the first rotating base 13, and thus obtain the swing angle of the pan-tilt unit 12 and the control box 9.

[0067] Furthermore, the connecting frame 2 also includes a second mounting part 23, which is disposed on the outer side wall of the sleeve part 211. The pitch detection element 41 is mounted on the second mounting part 23 and is connected to the second rotating shaft 16. The second rotating shaft 16 rotates, causing the second rotating base 14, the gimbal 12 and the control box 9 to pitch.

[0068] Furthermore, the rotation detection assembly 4 also includes a mounting base 43, which is mounted on the second mounting part 23, and the pitch detection component 41 is mounted on the mounting base 43.

[0069] Specifically, the encoder for detecting the pitch angle is connected to the second rotating shaft 16 to drive the code disk of the encoder for detecting the pitch angle to rotate. The manual operation handle 17 drives the second rotating shaft 16 to rotate, which in turn drives the second rotating base 14, the pan-tilt head 12 and the control box 9 to pitch, and also drives the code disk of the encoder for detecting the pitch angle to rotate, so as to detect the pitch angle of the second rotating base 14, and thus obtain the pitch angle of the pan-tilt head 12 and the control box 9.

[0070] It should be noted that the pitch and roll angles of the prop cannon 100 do not need to be scaled and can be directly applied to the virtual cannon. The pitch and roll angles of the prop cannon 100 will not exceed the pitch and roll angles of the virtual cannon.

[0071] Figure 5 This is merely an example of the connections between the various components in the prop cannon 100 used for virtual filming, such as... Figure 5 As shown, the controller 3 includes a first row of female connectors 31 and a second row of female connectors 32. The first row of female connectors 31 and 32 serve as connectors between the controller 3 and other components, and both the first row of female connectors 31 and 32 have multiple pins. Similarly, the prop cannon 100 used for virtual shooting includes a cannon nut 02, which is located inside the control box 9 and serves as a connector between the bracket 1 and other components. The cannon nut 02 also has multiple pins. The pitch detection component 41, sway detection component 42, boom length joystick 51, boom length zoom knob 52, display module 6, and radio frequency transmission module 7 are all connected to the first row of female connectors 31 and / or the second row of female connectors 32. The zeroing button 01, restart button 10, maximum value setting knob 531, maximum value cancellation knob 532, minimum value setting knob 533, and minimum value cancellation knob 534 are connected to the pins of the boom liner 02. The boom liner 02 is then connected to the first row of female connectors 31 and / or the second row of female connectors 32, thereby connecting each component to the controller 3 so that the controller 3 can receive information and transmit the information to the virtual shooting system 200 through the radio frequency transmission module 7 and the radio frequency receiving module 300, so as to provide real motion data for the virtual gun.

[0072] Although the present invention has been described in detail above with general descriptions, specific embodiments, and experiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
