Problems solved by technology

[0002] The gimbal is the supporting device for installing and fixing the camera. When the gimbal is installed on the unmanned aerial vehicle, if the gimbal is not adjusted properly, it may cause the following problems: the unadjusted gimbal will produce abnormal Balanced torque, while the motor installed on the gimbal continues to output current to provide unbalanced torque, which generates heat and causes energy loss. At the same time, the motor heats up. If the center of gravity is poorly adjusted and used for a long time, the motor may be damaged. ;The motor provides unbalanced torque, which may lead to a decrease in the performance of the gimbal system and affect the performance of image stabilization
[0003] When adjusting the cloud platform in the prior art, most of the adjustment methods are to judge the offset and offset direction of the cloud platform through human experience, but the cloud platform is adjusted by the obtained offset and offset direction. Adjustment, this is difficult for users who do not understand the relevant technologies to complete, and human error will affect the accuracy of the obtained offset and offset direction, which will affect the stability and reliability of the gimbal.

Embodiment 1

[0062] This embodiment provides a pan-tilt adjustment method, figure 1 It is a schematic flowchart of the pan-tilt adjustment method provided in Embodiment 1 of the present invention; refer to the attached figure 1 As shown in the figure, this adjustment method is used to adjust the center of gravity of the gimbal to keep the gimbal stable, avoiding the generation of multiple motor motion compensation torques in order to keep the gimbal stable, thereby ensuring that the gimbal uses Stable and reliable; specifically, a camera device is arranged on the pan / tilt, wherein the camera device may be a camera or a mobile phone and other shooting devices; the pan / tilt includes at least one drive motor; the pan / tilt adjustment method includes:

[0063] S101: Acquire torque information of at least one drive motor;

[0064] Wherein, there is no limitation on the specific number of drive motors set on the PTZ, for example, the number of drive motors can be set to 1, 2, or 3, etc.; in addi...

Embodiment 2

[0071] figure 2 This is a schematic flowchart of the pan-tilt adjustment method provided in the second embodiment of the present invention; on the basis of the above-mentioned first embodiment, continue to refer to the appendix Figure 1-2 It can be seen that this embodiment does not limit the acquisition method for acquiring the torque information of the at least one drive motor, wherein, it is more preferable to obtain the torque information of the at least one drive motor, and the settings are specifically set to include:

[0072] S1011: Acquire current information of at least one drive motor;

[0073] Wherein, the current information of the above at least one driving motor is the actual current information of the driving motor in a normal working state, that is, it does not include the current information of the driving motor in an abnormal working state (when the driving motor is started, when it is turned off, or when it is damaged). and rated current information; in a...

Embodiment 3

[0079] image 3 This is a schematic flowchart of the pan-tilt adjustment method provided in the third embodiment of the present invention; on the basis of the above-mentioned first or second embodiment, continue to refer to the attached image 3 It can be seen that the implementation process of determining the offset information of the center of gravity of the camera device relative to the motor shaft of the at least one driving motor is not limited in this embodiment. The offset information of the center of gravity of the camera device relative to the motor shaft of the at least one driving motor is set to specifically include:

[0080] S1021: Determine the offset information of the center of gravity of the camera with respect to the motor shaft of the at least one driving motor according to M=L*G, where M is the torque information of the driving motor, L is the offset information, and G is the preset value of the camera. set gravity information.

[0081] Wherein, the offse...

Abstract

A cradle head adjusting method, system and device and a cradle head are disclosed. The cradle head is provided with a camera (12) and comprises at least one driving motor (1, 9, 10, 18). The cradle head adjusting method comprises the following steps of obtaining torque information of at least one drive motor (S101); determining the center of gravity of the image pickup device relative to the offset information of the motor shaft of at least one drive motor based on the torque information and the gravity information preset by the imaging device (S103); the headset adjustment method, the pan / tilt adjusting device, the head, and the unmanned aerial vehicle are automatically adjusted according to the offset information (S103), and when the pan / tilt is adjusted, It is difficult to complete the input of the user, and because the human error will affect the accuracy of the offset and offset direction, and thus affect the stability and reliability of the use of PTZ, and thus ensure that the PTZ adjustment Accurate reliability, but also improve the stability of the use of PTZ reliability.

Description

technical field [0001] The invention relates to the technical field of pan-tilt adjustment, in particular to a pan-tilt adjustment method, system, device and pan-tilt. Background technique [0002] The gimbal is a supporting device for installing and fixing the camera. When the gimbal is installed on the UAV, if the gimbal is not adjusted properly, it may cause the following problems: the unadjusted gimbal will cause inconsistencies. Balance the torque, while the motor installed on the gimbal continues to output current to provide unbalanced torque, which generates heat and causes energy loss. At the same time, the motor heats up. If the center of gravity is poorly adjusted and used for a long time, the motor may be damaged. ; The motor provides unbalanced torque, which may cause the performance of the gimbal system to degrade and affect the performance of image stabilization. [0003] In the prior art, when adjusting the gimbal, most of the adjustment methods are to judge ...
