The real-time distance information may be distance-related sensing data sensed by the distance measuring device 10, or may be a real-time distance value calculated by the distance measuring device 10 according to the distance-related sensing data sensed by itself. When the real-time distance information is a real-time distance value, the processor of the driving device 200 can directly calculate the real-time output torque of the driving motor 210 according to the real-time distance information between the subject and the distance measuring device 10. When the real-time distance information is the sensing data, the processor of the driving device 200 calculates the real-time distance value between the camera 400 and the distance measuring device 10 according to the sensing data, and then calculates the real-time output torque of the driving motor 210 according to the real-time distance value.

Referring to fig. 1, the distance measuring device 10 may be installed on the top, any side surface or the bottom of the photographing device 400, only by ensuring a predetermined included angle is formed between the optical axis of the emitting unit 13 and the horizontal plane. Generally, a hot shoe or a cold shoe for connecting other devices is provided on the top of the photographing apparatus 400, and the distance measuring apparatus 10 can be installed on the top of the photographing apparatus 400 and connected with the hot shoe or the cold shoe of the photographing apparatus 400. The distance measuring device 10 may also be clamped to the top, either side or bottom of the camera 400 in conjunction with a clamping structure.

Referring to fig. 3 and 4, in some embodiments, the distance measuring device 10 may further include a control key 15. The control keys 15 may be located on the top, bottom or either side of the distance measuring device 10. The control key 15 is used for controlling the driving apparatus 200 to enter the calibration mode according to the first operation and switching the operation mode of the driving apparatus 200 according to the second operation, and the operation mode includes a first operation mode and a second operation mode.

When the driving device 200 is in the first operating mode, the driving device 200 is configured to drive the lens 410 of the photographing device 400 to move according to the real-time distance information for auto-focusing and/or auto-zooming, and at this time, the driving device 200 does not depend on the control of the control device 300, but automatically drives the lens 410 of the photographing device 400 to move according to the real-time distance information.

When the driving device 200 is in the second operation mode, the driving device 200 drives the lens 410 of the photographing device 400 to move for manual focusing and/or manual zooming according to the control of the control device 300, and at this time, the driving device 200 does not drive the lens 410 of the photographing device 400 to move according to the real-time distance information any more, but responds to the operation of the control device 300 by the user.

The control key 15 includes any one of a button, a knob, a slide switch, and a virtual touch key. Taking the control key as an example, the first operation may be double-clicking the button, and the second operation may be single-clicking the button. After the first operation, the driving apparatus 200 can be actively controlled to enter a calibration mode, in which the driving apparatus 200 can be calibrated according to the focal length or focal length of the lens 410 currently configured by the photographing apparatus 400, so that the driving apparatus 200 can be adapted to the lens 410 currently configured by the photographing apparatus 400. After the second operation, the operation mode of the driving device 200 can be switched, for example, from the first operation mode to the second operation mode, or from the second operation mode to the first operation mode, so as to automatically or manually control the driving device 200 according to the requirement, so as to realize automatic or manual focusing and/or zooming.

Referring to fig. 3 and 4, in some embodiments, the distance measuring device 10 may further include an indication unit 16. The indicating unit 16 may be located on the top, bottom or either side of the distance measuring device 10. The indication unit 16 is used for indicating the current state of the driving device 200, i.e. for indicating any one of the first operation mode, the second operation mode, or the to-be-calibrated mode.

Wherein the to-be-calibrated mode includes indicating that the driving apparatus 200 does not enter the calibration mode. In one embodiment, when the driving device 200 is used to drive the lens 410 of the photographing device 400 to move for focusing and/or zooming, a calibration operation is first required, and the indicating unit 16 indicates that the driving device 200 is currently in the to-be-calibrated mode. If the drive device 200 is not calibrated before calibration is performed, the drive device 200 may be calibrated by entering the drive device 200 into the calibration mode by performing a first operation on the control key 15, or the drive device 200 may automatically enter the calibration mode. When the driving device 200 is calibrated, a calibration operation may be performed. During calibration, the driving device 200 needs to control the lens 410 to complete focusing at least two focusing calibration points, so as to complete calibration of the mapping relationship between the real-time distance information between the distance measuring device 10 or the photographing device 400 and the object to be photographed and the rotation position of the driving motor 210 of the driving device 200. After the calibration is completed, the operation mode of the driving apparatus 200 is automatically switched to the first operation mode or the second operation mode, or the operation mode of the driving apparatus 200 is manually switched to the first operation mode or the second operation mode, and at this time, the indicating unit 16 correspondingly indicates the current state of the driving apparatus 200.

In one embodiment, the indication unit 16 is a display screen capable of indicating the current state of the driving device 200 through text and/or images. At this time, the indication unit 16 may be installed at the top or any side of the distance measuring device 10.

In another embodiment, the indication unit 16 is an audio indicator, such as a speaker, which can indicate the current state of the driving device 200 through voice broadcast. At this time, the indicating unit 16 may be installed at the top, bottom, or either side of the distance measuring device 10.

In yet another embodiment, the indication unit 16 is an indicator light, and the indicator light indicates the current state of the driving device 200 through the color of the indicator light and/or the flashing rule (e.g. flashing frequency) of the indicator light. For example, the indicator light can keep a green light constantly on to indicate that the driving device 200 is in the first operating mode, the indicator light can keep a yellow light constantly on to indicate that the driving device 200 is in the second operating mode, and the indicator light can keep a red light constantly on to indicate that the driving device 200 is in the to-be-calibrated mode. When the lens 410 of the shooting device 400 needs to be driven to move for focusing and/or zooming by using the driving device 200, if the calibration is not performed, the indicator light keeps the red light on normally. After the calibration is completed, the indicator light is changed from the red light being normally on to the yellow light being normally on or the green light being normally on according to the current state of the driving device 200. When the driving device 200 changes from the first operation mode to the second operation mode, the indicator light changes from the green light to the yellow light. When the driving device 200 changes from the second operation mode to the first operation mode, the indicator light changes from the yellow light to the green light. Of course, the first operating mode, the second operating mode, and the to-be-calibrated mode are distinguished and indicated only by taking a yellow light, a green light, and a red light as examples, and actually, the first operating mode, the second operating mode, and the to-be-calibrated mode may be distinguished and indicated by using other different colors as long as the colors corresponding to the three modes are different from each other.

Conversely, the pressing member 43 can rotate relative to the engaging member 41 (as opposed to the rotation for increasing the interference force), so that the interference force between the pressing member 43 and the to-be-connected component 50 can be reduced, and the engaging member 41 can move relative to the to-be-connected component 50, so as to adjust the position of the to-be-connected component 40 relative to the to-be-connected component 50 or detach the to-be-connected component 40.

When the connecting part 40 needs to be detached from the part 50 to be connected, the abutting force between the pressing piece 43 and the part 50 to be connected is reduced, the combining piece 41 can move relative to the part 50 to be connected, and then the abutting of the combining piece 41 and the part 50 to be connected is released, so that the connecting part 40 can be detached quickly. When the connection part 40 needs to be installed on the part 50 to be connected, the connection part 40 can be installed quickly only by abutting the combining part 41 against the part 50 to be connected and increasing the abutting force between the pressing part 43 and the part 50 to be connected so that the combining part 41 cannot move relative to the part 50 to be connected.

In one embodiment, the member to be connected 50 may be a camera 400.

For example, the first end 511 of the mounting member 51 is provided with a dovetail groove, the photographing device 400 is provided with a screw structure, and the fastening member 53 is a screw. The engaging pieces 41 in the connecting part 40 are engaged with the dovetail grooves and then pressed by the pressing pieces 43 to fixedly connect the connecting part 40 and the part 50 to be connected.
