The shooting monitor apparatus 13 is connected to the pan-tilt power unit 11, specifically, to the shooting apparatus connecting part 111 of the pan-tilt power unit 11, and when the shooting apparatus connecting part 111 drives the shooting apparatus to move, the shooting monitor apparatus 13 moves together therewith. In addition to the pan-tilt power device 11, the shooting monitor device 13 is also connected with the shooting device and the mobile device, and is used for transmitting the video shot by the shooting device to the mobile device for displaying, and controlling the shooting device and the pan-tilt system according to the control instruction sent by the mobile device. The shooting monitor apparatus 13 is described below with reference to fig. 2:
the shooting monitor apparatus 13 includes a USB interface 131, a UART interface 132, a WiFi module 133, and a processing unit 134, wherein the USB interface 131 of the shooting monitor apparatus 13 is used to connect with the shooting apparatus 14, the UART interface 132 is used to connect with a main control unit 1111 in the cradle head power device 11, and the WiFi module 133 is used to connect with the mobile apparatus 15. The workflow of the photographing monitoring apparatus 13 includes: the photographing monitoring device 13 receives video (which is composed of consecutive picture frames) captured and transmitted in real time by the photographing device 14 via the USB interface 131; the USB interface 131 transmits video to the processing unit 134, and the processing unit 134 transmits video wirelessly (through a WiFi connection) to the mobile device 15 via the WiFi module 133, whereby a user can view video captured by the photographing device 14 in real time on the mobile device 15 (wherein the mobile device can discard some of the picture frames transmitted by the photographing monitoring device 13 without affecting the viewing effect). If the user desires to adjust the photographing effect according to the video being watched, the related control command, which may be a photographing apparatus control command or a pan-tilt system control command, may be transmitted to the photographing monitoring apparatus 13 through the mobile apparatus 15, the former is used to adjust parameters of the photographing apparatus 14 or control some operations of the photographing apparatus 14 (e.g., stop photographing, start photographing, etc.), and the latter is used to change an operation mode of the pan-tilt system (including a follow mode, a full follow mode, a quick follow mode, a lock mode), perform on/off operations on the pan-tilt system, or adjust the posture of the pan-tilt system to control the movement of the camera, etc. The photographing monitoring device 13 receives a control command from the mobile device 15 via the WiFi module 133, and the WiFi module 133 transmits the control command to the processing unit 134. The processing unit 134 is configured to identify whether the control command is a camera control command or a pan-tilt system control command, and if the control command is identified as a camera control command, send the camera control command to the camera 14 via the USB interface 131, and the camera 14 adjusts parameters or performs other operations according to the camera control command; if the control command is identified as a pan-tilt system control command, the pan-tilt system control command is sent to the main control unit 1111 in the pan-tilt power device 11 via the UART interface 132, and the main control unit 1111 controls the rotation of the shafts 112 to 114 according to the pan-tilt system control command, so as to realize the movement of the photographing apparatus 14 desired by the user, adjust the pan-tilt control parameters into the working mode desired by the user, or perform some other operations on the pan-tilt system.
With the cradle head system, a user can know the current shooting effect of the shooting device 14 through the mobile device 15, and can control the shooting device 15 and the cradle head system through the mobile device 14, so that the shooting device 14 shoots in a mode expected by the user, the cost required for purchasing the external display device is reduced, and the shooting work of the user is facilitated. The photographing monitoring device 13 is located near the photographing device connecting part 111 and the main control unit 1111, so that the USB data line between the photographing device 13 and the photographing device 14 does not affect the movement of the pan-tilt power unit 11, and the data line between the photographing device and the main control unit 1111 does not pass through the parts such as the shafts 112-114 and the connecting arm, so that the stability enhancement effect of the pan-tilt system is not affected.
In the above embodiment, the processing unit 134 directly transmits the video captured by the photographing device 14 in real time and transmitted via the USB interface 131 to the mobile device 15 through the WiFi module 133, however, since the WiFi connection has a delayed volatility, the mobile device 15 is affected to display the video (i.e. continuous picture frames) received by the mobile device 15. In a preferred embodiment, the processing unit 134 captures the picture frames in the video at certain time intervals (e.g., 40 ms), encapsulates the captured picture frames such that the encapsulated picture frames include their transmission times, and finally transmits the encapsulated picture frames to the mobile device 15 via the WiFi module 133. After receiving the encapsulated picture frame, the mobile device 15 firstly decapsulates to obtain the sending time of the picture frame, and selects the time and duration of the display of the picture frame on the screen according to the sending time of the picture frame, so that a better video playing effect is obtained for the current WiFi environment, in addition, the processing unit 134 only encapsulates and transmits a part of the acquired picture frame (acquired once every 40 milliseconds as described above) to the mobile device 15 for display, the burden of WiFi connection is reduced while the display effect is not affected, and the video playing effect of the mobile device 14 is further improved.
For various existing photographic devices, each picture frame in the video taken by the device or the picture taken by the device generally contains parameter information when the photographic device 14 captures the picture frame or the picture, in a preferred embodiment, the mobile device 15 also extracts parameter information of the photographic device 14 from the received picture frame and presents to the user along with the picture frame, so that the user can learn some current parameter information of the photographic device 14, in addition, the processing unit 134 can acquire some other relevant information (such as electric quantity, etc.) of the photographic device 14 in real time via the USB interface 131 and transmit to the mobile device 15 via the WiFi module 133 for presentation to the user, specifically, the processing unit 134 sends a request to the photographic device 14 via the USB interface 131 and receives the information returned by the photographic device 134. Furthermore, as described above, the posture plate 115 in the pan-tilt power apparatus 11 can sense the posture of the photographing device 14 in real time and transmit the sensed posture information to the main control unit 1111, in this embodiment, the processing unit 134 may also acquire the posture information of the photographing device 14 and some other related information of the pan-tilt system, such as the current operation mode, the current electric quantity, etc., from the main control unit 1111 via the UART interface 132, and then the processing unit 134 transmits the related information of the pan-tilt system to the mobile device 15 via the WiFi module 133 for display to the user. In this way, the user can learn the current state of the photographing apparatus 14 and the pan-tilt system in addition to the current photographing effect, so that a correct control command can be issued, which further facilitates the photographing work of the user.
In the above-described embodiment, the photographing apparatus control command transmitted by the user through the mobile apparatus 15 may be applicable only to a part of photographing apparatuses currently on the market, and the photographing monitoring apparatus 13 is part of the pan-tilt system. However, the shooting and monitoring apparatus 13 may also be an electronic apparatus independent of the cradle head system, and since the existing cradle head system is generally provided with a data interface connected to its main control unit, the existing cradle head system may be externally connected to the shooting and monitoring apparatus 13 (i.e. the UART interface 132 connected to the shooting and monitoring apparatus 13) through the data interface (UART interface) to achieve the object of the present invention. In this case, the pan-tilt system control command sent by the user through the mobile device 15 in the above embodiment may also be incompatible with the existing pan-tilt system. Fig. 3 shows an embodiment for solving this problem, and as shown in fig. 3, the photographing monitoring apparatus 13 further includes a storage unit 135. The storage unit 135 stores control protocols corresponding to various models of photographing apparatuses and control protocols corresponding to various models of pan-tilt systems. After receiving the control command from the mobile device 15, the processing unit 134, in addition to identifying whether the control command is a photographing device control command or a pan-tilt system control command, converts the control command according to the control protocol stored in the storage unit 135 so that the converted control command is compatible with the current photographing device 14 and pan-tilt system, and finally sends the converted control command to the main control unit 1111 in the photographing device 14 or the pan-tilt power apparatus 11.
Specifically, the photographing monitoring apparatus 13, after being connected to the photographing apparatus 14 and the main control unit 1111 in the cradle head power device 11, the processing unit 134 thereof acquires model information of the photographing apparatus 14 via the USB interface 131 and model information of the cradle head system from the main control unit 1111 via the UART interface 132, and these model information may be stored in the storage unit 135. When receiving a control command from the mobile device 15 via the WiFi module 133, the processor 134 first recognizes whether the control command is a photographing device control command or a cradle head system control command, and if recognized as a photographing device control command, the processor 134 searches for a control protocol corresponding to model information of the current photographing device 14 from the storage unit 135 and converts the photographing device control command into a control command compatible with the current photographing device 14 according to the found control protocol; if the control command is identified as a pan-tilt system control command, the processor 134 searches the control protocol corresponding to the model information of the current pan-tilt system from the storage unit 135, and converts the pan-tilt system control command into a control command compatible with the current pan-tilt system according to the found control protocol. Finally, the processing unit 134 transmits the converted photographing apparatus control command or the cradle head system control command to the photographing apparatus 14 or the main control unit 1111 via the USB interface 131 or the UART interface 132, respectively. Since the photographing monitoring apparatus 13 is compatible with various photographing apparatuses and cradle head systems, its applicability and practicality are also high.
In the above-described embodiment, the data transmission between the photographing monitoring apparatus 13 and the photographing apparatus 14 and before the photographing monitoring apparatus 13 and the main control unit 1111 of the cradle head system is possible to be bidirectional, so there is competition in the connection channel, and the user generally expects that he can watch the video collected by the photographing apparatus 14 on the mobile apparatus 15 in real time and expects that the photographing apparatus 14 and the cradle head system can respond to the control command thereof in time. In view of this, in a preferred embodiment, the processing unit 134 performs a merging operation for a period of time on the photographing apparatus control command transmitted to the photographing apparatus 14 (for example, first receives a control command to set ISO to 100, then receives a control command to set ISO to 200 within the period of time, and then the processing unit 134 retains only the control command to set ISO to 200), and transmits the photographing apparatus control command obtained after merging to the photographing apparatus 14, the effect obtained from the control command obtained after merging being the same as the effect obtained from the plurality of control commands within the period of time; while the video (successive picture frames) received from the photographing apparatus 14 is subjected to a read optimizing operation. The processing unit 134 may also perform filtering operations on the pan-tilt system control commands sent to the main control unit 1111, for example, to filter out some control commands that conflict with the state of the current pan-tilt system according to the acquired current related information of the pan-tilt system (for example, the current operation mode of the pan-tilt system is a locking mode, and the pan-tilt system control commands indicate that the photographing apparatus 14 is lifted in the pitching direction). Those skilled in the art will appreciate that other time-division multiplexing techniques may be employed for the connection channels to achieve the above-described objectives of real-time display and timely control.
It should be understood that, although the description is given above taking video as an example, the pan-tilt system and the photographing monitoring device 13 provided by the present invention may also implement display of pictures (photographs) taken by the photographing device 14 on the mobile device 15. In addition to the USB connection, the processing unit 134 may be connected to the photographing apparatus 14 through UART technology or other wired data transmission technology, and the processing unit 134 may also be connected to the photographing apparatus 14 through wireless technology. Similarly, the processing unit 134 may also be connected to the main control unit 1111 in the pan/tilt head power device 11 by a wired connection such as USB, SPI, or by a wireless connection.
In addition to being connected to the mobile device 15 through the WiFi module 133, the processing unit 134 may also be connected to the mobile device 15 through other wireless communication technologies, or may be connected to the mobile device 15 through two wireless communication technologies (such as WiFi and bluetooth), for example, the processing unit 134 may prefer to connect to the mobile device 15 through its WiFi module 133, to connect to the mobile device 15 through the bluetooth module when a WiFi connection is detected to be disconnected, and to connect to the mobile device 15 through the WiFi module 133 after a WiFi connection is detected to be reconnected. In addition, the processing unit 134 may also communicate with the mobile device via a wired connection. For example, the photographing monitoring apparatus 13 provides another USB interface (different from the USB interface 131) via which the processing unit 134 is connected to the mobile device.
In the above embodiment, the main control unit 1111 is located in the photographing apparatus connecting part 111 of the cradle head power device 11, and the photographing monitoring apparatus 13 is connected to the photographing apparatus connecting part 111. The advantage of this structure is that the data line between the photographing monitoring device 13 and the main control unit 1111 does not obstruct the movement of the pan-tilt power device 11, and does not pass through the shafts 112-114 and the connecting arms, so that interference is not caused to some of the components, and the stability enhancement effect of the pan-tilt system is not affected.
