The structure of the multi-function camera according to the embodiment of the present invention will be further explained below.
Referring to fig. 1, the connector 1 is provided with a first data interface 11 and a first mounting location 12. In this embodiment, the first data interface 11 is a multi-contact or multi-pin interface, and the first data interface 11 may also adopt an interface similar to a USB interface or a network interface. In this embodiment, the first data interface 11 includes a plurality of pins. A part of pins in the first data interface 11 may be used as a power interface, and a part of pins may be used as a data transmission and signal synchronization interface.
The pin of the first data interface 11 used as the power interface can be connected to an external power source to serve as the main power source of the multifunctional camera.
The pins of the first data interface 11 used as the data transmission and signal synchronization interface may be in communication connection with the first external device 300, and the pins of the first data interface 11 used as the data transmission and signal synchronization interface also need to be in communication connection with the camera body 100 set as a master and/or a slave, so as to implement communication between the multifunctional camera and the first external device 300. For example, the master and/or the slave receives a control signal from the first external device 300 through the first data interface 11 or transmits an image, video data, etc. to the first external device 300 through the first data interface 11. In this embodiment, the first external device 300 only needs to be in communication connection with the camera body 100 as the host, and does not need to separately communicate with other camera bodies 100, so that the multifunctional camera of the embodiment of the present invention is simpler and more convenient to use. Of course, in other embodiments, the first external device 300 may also simultaneously and separately communicate with each camera body 100, so that each camera body 100 may directly send the image to the first external device 300 and the first external device 300 performs post-fusion and processing on each collected image.
The first mounting position 12 is used for connecting with a second external device to fix the connecting member 1 to the second external device, thereby fixing the multifunctional camera to the second external device. In some examples, the first external device 300 and the second external device are the same device, such as the pan/tilt head 200. In other examples, the first external device 300 and the second external device are independent from each other, for example, in a practical application scenario, the first external device 300 is a mobile phone, and the second external device is the wearable device 400. The first mounting portion 12 may be a plurality of mounting structures, for example, a hook or a slot suitable for a snap connection, a threaded hole or a through hole suitable for a threaded connection or a bolt connection, and so on. In this embodiment, the first mounting position 12 is a mounting hole structure.
In order to prevent blocking of the shooting view of the camera body 100 and to balance the left and right centers of gravity of the multifunctional camera, all the rotation members 2 are distributed around the first mounting position 12. Optionally, all the rotating parts 2 are uniformly distributed around the first mounting position 12 or all the rotating parts 2 are symmetrically distributed on both sides of the first mounting position 12.
Each rotor 2 is provided with a second data interface 21 and a first mounting portion 22. In this embodiment, the second data interface 21 is a multi-contact or multi-pin interface, and the second data interface 21 may also adopt an interface similar to a USB interface or a network interface. In this embodiment, the second data interface 21 includes a plurality of pins. Some pins in the second data interface 21 may be used as a power interface, some pins may be used as a data transmission and signal synchronization interface, some pins may be used as a host and slave identification interface, and some pins may be used as a host and/or slave and a first external device communication interface.
The pin of the second data interface 21 used as the power interface may be connected to the pin of the first data interface 11 used as the power interface to supply power to the corresponding camera body 100.
The pin of the second data interface 21 used as the data transmission and signal synchronization interface may be in communication connection with the camera body 100 disposed on the corresponding rotating member 2, and the pin of the rotating member 2 where the slave is located used as the data transmission and signal synchronization interface is in communication connection with the pin of the rotating member 2 where the master is located used as the data transmission and signal synchronization interface, that is, the master and the slave are in communication connection through the second data interface 21, thereby realizing communication between the master and the slave. For example, the master sends a synchronization signal to the slave through the second data interface 21 to achieve synchronous image acquisition, or the slave sends an image acquired by the slave through the second data interface 21 to the master.
The pins of the second data interface 21 as the identification interfaces of the master and the slave can realize the identification and switching between the master and the slave. In this embodiment, each of the rotating components includes a pin used as the identification interface between the master and the slave, and for convenience of description, in this embodiment of the present invention, the pin used as the identification interface between the master and the slave is also referred to as the master-slave identification interface. Optionally, in order to realize automatic identification and switching between the master and the slave, the master-slave identification interface on each rotating member respectively pulls up or pulls down the resistor, and the resistance value corresponding to the master-slave identification interface on the rotating member provided with the master is different from the resistance value corresponding to the master-slave identification interfaces on the other rotating members provided with the slave, so as to set one of the at least two camera bodies 100 as the master and the other as the slave.
For example, when three rotation members 2 are provided, and one camera body 100 is connected to each of the three rotation members 2, one of the rotation members 2 includes a master-slave identification interface for pulling up a 250-ohm resistor, and the other two rotation members 2 include a master-slave identification interface for pulling up a 50-ohm resistor, respectively, the camera body 100 on the rotation member 2 corresponding to the master-slave identification interface for pulling up the 250-ohm resistor is set as the master, and the other two camera bodies 100 are set as slaves. In the embodiment of the present invention, the rotor 2 provided with the master is referred to as a master bit, the rotor 2 provided with the slave is referred to as a slave bit, and the second data interface 21 for performing communication between the master and the slave is also referred to as a master-slave data interface.
The pins of the second data interface 21, which are used as communication interfaces between the master and/or slave and the first external device 300, can realize communication between the master and/or slave and the first external device 300, so as to facilitate user operation. The pin used as the communication interface between the master and the first external device 300 is located on the master position, and the pin used as the communication interface between the slave and the first external device 300 is located on the slave position.
In this embodiment, the first external device 300 only needs to communicate with the host, and the slave communicates with the host, and the host processes the images and then sends them to the first external device 300. A pin on the host site used as a communication interface between the host and the first external device may be correspondingly connected to a pin of the first data interface 11 used as a data transmission and signal synchronization interface, so as to implement communication connection between the host and the first external device 300. For example, the host transmits an image to the first external device 300 through the second data interface 21, or the host receives a control signal from the first external device 300 through the second data interface 21.
In other embodiments, the first external device 300 may simultaneously and respectively communicate with the camera bodies 100, and the collected images are post-fused and processed by the first external device 300. In this embodiment, corresponding pins on the master station and the slave station are correspondingly connected to pins of the first data interface 11, which are used as data transmission and signal synchronization interfaces, respectively, so as to implement communication connection between the first external device 300 and each camera body 100.
Each camera body 100 is provided with an external interface 101. The external interface 101 is a multi-contact or multi-pin interface, and the external interface 101 may also be an interface similar to a USB interface or a network interface. In the present embodiment, the external interface 101 on each camera body 100 includes a plurality of pins. Some pins in the external interface 101 may be used as a power interface, and some pins may be used as a data transmission and signal synchronization interface.
Pins of the external interface 101 used as a power interface may be correspondingly connected with pins of the second data interface 21 used as a power interface, so as to supply power to the corresponding camera body 100.
Pins used by the data transmission and signal synchronization interface of the external interface 101 may be correspondingly connected with pins used as the data transmission and signal synchronization interface of the second data interface 21, so as to realize the data transmission and signal synchronization functions of each camera body 100 and the corresponding rotating member 2.
The first mounting portion 22 is used for mounting a corresponding camera body 100, for example, the first mounting portion 22 is connected to the bottom of the camera body 100, so that the camera body 100 is fixed to the rotation member 2. The camera body 100 is provided with a second mounting portion 102 that is engaged with the first mounting portion 22 of the corresponding rotating member 2.
