[0019] The scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

If the specific posture changes, the directional indication will also change accordingly.

[0021] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0022] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0023] To achieve the above-mentioned purpose, the present invention proposes a method for adjusting the optical transmittance of a drone gimbal, and the method for adjusting the optical transmittance of a drone gimbal includes: Step S110, receiving a transmittance adjustment signal; Step S120, analyzing the transmittance adjustment signal to obtain a voltage adjustment parameter and a pulse width adjustment parameter; Step S130, obtaining a neutral gray filter adjustment parameter according to the voltage adjustment parameter and the pulse width adjustment parameter; Step S140, adjusting the transmittance of the neutral gray filter according to the neutral gray filter adjustment parameter.

[0024] In this embodiment, refer to Figure 1 and Figure 8 , the transmittance adjustment method of the unmanned aerial vehicle gimbal optics is applied to the transmittance adjustment system of the unmanned aerial vehicle gimbal optics; the transmittance adjustment system of the unmanned aerial vehicle gimbal optics is used to adjust the transmittance of the neutral gray filter of the gimbal optical device on the unmanned aerial vehicle, wherein the neutral gray filter is an ND (Neutral-Density Filter) filter. The transmittance adjustment system of the unmanned aerial vehicle gimbal optics includes a unmanned aerial vehicle and a user end. The user end can be used to control the unmanned aerial vehicle; the unmanned aerial vehicle can be used to execute various control instructions sent by the user end. The user end can include a transmittance adjustment module, and the transmittance adjustment module can generate control parameters according to the user's toggling of the handwheel controller. The unmanned aerial vehicle can include an unmanned aerial vehicle body and a gimbal optical device; the unmanned aerial vehicle body is used to load the gimbal optical device. The gimbal optical device can include a data processing module, a neutral gray filter adjustment module and an image acquisition module; the data processing module can process various operation data; the neutral gray filter adjustment module can adjust the transmittance of the ND filter; the image acquisition module can acquire external image data. In this embodiment, the execution subject of the method steps is the gimbal optical device in the unmanned aerial vehicle.

[0025] It is understandable that the filter unit of the ND filter can be filled with liquid crystal glass of variable transmittance material, and the control module adjusts the transmittance of the filter unit by adjusting the width and time of the voltage pulse of the wire; wherein the control module may include a data processing module and a neutral gray filter adjustment module. When the wire applies voltage pulses with different widths and time intervals, the average value of the orientation change of the liquid crystal molecules in the filter unit changes, and as the applied voltage pulse increases and the time interval decreases, the transmittance of the filter unit decreases accordingly.

[0026] When users control the gimbal optical device of the drone through the user end to take aerial photos and obtain remote image data in real time, they will be affected by different lighting conditions such as strong light and weak light during the aerial photography process. For example, if clouds suddenly cover the sun, the light will suddenly change from strong light to weak light; conversely, it will suddenly change from weak light to strong light. At this time, the quality of the image data obtained by the user through the user end will be affected. If the user wants to eliminate the influence of light intensity on the image data quality, the user can generate a transmittance adjustment signal through the transmittance adjustment module of the user end, and send the transmittance adjustment signal to the gimbal optical device of the drone, thereby controlling the gimbal optical device to adjust the transmittance of the ND filter.

[0027] A handwheel controller may be provided on the user end, and there may be multiple transmittance scales on the handwheel controller, each scale may represent a transmittance value corresponding to a transmittance; when the pointer on the handwheel controller points to a scale, the transmittance value corresponding to this scale may be used as the target transmittance desired by the user. The transmittance adjustment module may generate a transmittance adjustment signal according to the target transmittance. After the user end generates the transmittance adjustment signal, it will send the transmittance adjustment signal to the drone. At this time, the gimbal optical device in the drone may receive the transmittance adjustment signal; wherein the transmittance adjustment signal may include the target transmittance. For example: if the target transmittance is 30%; then the information included in the transmittance adjustment signal may be to adjust the transmittance of the ND filter to 30%.

[0028] After receiving the transmittance adjustment signal, the PTZ optical device will analyze the transmittance adjustment signal, obtain the target transmittance from the transmittance adjustment signal, and then configure the voltage adjustment parameter and the pulse width adjustment parameter according to the target transmittance. For example, configure a specific voltage adjustment parameter and a specific pulse width adjustment parameter according to adjusting the transmittance of the ND filter to 30%.

[0029] After the pan / tilt optical device obtains the voltage adjustment parameter and the pulse width adjustment parameter, the adjustment parameter of the ND filter can be generated according to the voltage adjustment parameter and the pulse width adjustment parameter. The adjustment parameter of the ND filter can be a voltage pulse synthesized by the voltage adjustment parameter and the pulse width adjustment parameter. For example, a voltage pulse that can adjust the transmittance of the ND filter to 30% can be synthesized according to a specific voltage adjustment parameter and a specific pulse width adjustment parameter.

[0030] After the PTZ optical device obtains the adjustment parameters of the ND filter, it can adjust the transmittance of the ND filter according to the adjustment parameters of the ND filter; that is, the transmittance of the ND filter is adjusted by the voltage pulse synthesized by the voltage adjustment parameter and the pulse width adjustment parameter. For example: applying a voltage pulse that can adjust the transmittance of the ND filter to 30% to the ND filter will adjust the transmittance of the ND filter to 30%.

[0031] Through this embodiment, the optical device of the gimbal of the drone can directionally adjust the transmittance of the neutral gray filter by receiving the transmittance adjustment signal sent by the user end; the user can remotely adjust the transmittance of the neutral gray filter in real time and accurately, thereby improving the efficiency and imaging quality of the drone's aerial photography operations, and enabling the drone to obtain high-quality image data under different lighting conditions.

[0032] In some embodiments, after adjusting the transmittance of the neutral gray filter according to the neutral gray filter adjustment parameter in the foregoing, the method further includes: Step S150, obtaining the adjusted light transmittance; Step S151, obtaining current image data according to the adjusted transmittance.

[0033] In this embodiment, refer to Figure 2 After executing step S140, the pan-tilt optical device will also obtain the image data after the transmittance is adjusted. The pan-tilt optical device configured on the drone is to obtain remote image data in real time; after adjusting the transmittance, the pan-tilt optical device can obtain the adjusted transmittance; and then the current image data can be obtained according to the adjusted transmittance.

[0034] The transmittance of the ND filter is adjusted by a voltage pulse synthesized by a voltage adjustment parameter and a pulse width adjustment parameter. However, there may be some other factors affecting the adjustment process, which may cause errors in the adjustment. The adjusted transmittance may have errors with the target transmittance in the transmittance adjustment signal. In a preferred embodiment, after obtaining the adjusted transmittance, it also includes parsing the transmittance adjustment signal to obtain the target transmittance, comparing the target transmittance with the adjusted transmittance, and obtaining a comparison result. The comparison result may be that the target transmittance is consistent with the adjusted transmittance, indicating that there is no adjustment error; the comparison result may also be that the target transmittance is inconsistent with the adjusted transmittance, indicating that there is an adjustment error.

[0035] In some embodiments, after obtaining the current image data according to the adjusted transmittance, the method further includes: Step S160, sending the current image data to the user end; Step S161, receiving a feedback signal generated by the user terminal according to current image data.

[0036] In this embodiment, refer to Figure 3 , the pan-tilt optical device needs to send the current image data to the user end before executing step S151. After the pan-tilt optical device adjusts the transmittance of the ND filter, the pan-tilt optical device will obtain the current image data according to the adjusted transmittance; however, after the pan-tilt optical device obtains the current image data, the pan-tilt optical device cannot determine whether the current image data meets the user's standards; at this time, the pan-tilt optical device needs to send the current image data to the user end. After the user end receives the current image data, the user can determine whether the image data meets the standards based on the current image data; the user end can generate a feedback signal based on the user's judgment, and then the user end can send the feedback signal to the pan-tilt optical device. At this time, the pan-tilt optical device can receive the feedback signal generated by the user end based on the current image data.

[0037] In some embodiments, the feedback signal includes an adjustment end instruction and a secondary adjustment instruction; after receiving the feedback signal generated by the user end according to the transmittance adjustment result, the method further includes: Step S170, detecting an instruction of a feedback signal; Step S171, if the instruction of the feedback signal is an adjustment end instruction, then the adjustment of the transmittance is ended according to the adjustment end instruction; Step S172: if the instruction of the feedback signal is a secondary adjustment instruction, the step of receiving a transmittance adjustment signal is executed.

[0038] In this embodiment, refer to Figure 4 After executing step S161, the pan-tilt optical device also needs to detect the instruction of the feedback signal. The feedback signal includes an adjustment end instruction and a secondary adjustment instruction. If the user determines that the image data meets the standard, the user end can generate an adjustment end instruction according to the user's determination. If the user determines that the image data does not meet the standard, the user end can generate a secondary adjustment instruction according to the user's determination.

[0039] If the PTZ optical device determines that the instruction of the feedback signal is an adjustment end instruction, it will end the adjustment of the transmittance according to the adjustment end instruction. When the instruction of the feedback signal is an adjustment end instruction, it means that the user determines that when the image data meets the standard, the user does not need to continue to adjust the transmittance of the ND filter; the PTZ optical device will end the adjustment of the transmittance of the ND filter according to the adjustment end instruction.

[0040] If the PTZ optical device determines that the instruction of the feedback signal is a secondary adjustment instruction, it will execute the step of receiving the transmittance adjustment signal. When the instruction of the feedback signal is a secondary adjustment instruction, it means that the user determines that the image data does not meet the standard, and the user needs to continue to adjust the transmittance of the ND filter; the user will continue to send the transmittance adjustment signal to the PTZ optical device through the user terminal.

[0041] In some embodiments, after obtaining the neutral gray filter adjustment parameter according to the voltage adjustment parameter and the pulse width adjustment parameter, the method further includes: Step S180, sampling the neutral gray filter adjustment parameters to obtain sampling parameters; Step S181, converting the sampling parameters into a sampling signal; Step S182, obtaining a voltage pulse of the sampling signal and a target voltage pulse of the transmittance adjustment signal; Step S183, comparing the voltage pulse of the sampling signal with the target voltage pulse of the transmittance adjustment signal to obtain a comparison result.

[0042] In this embodiment, refer to Figure 5When the pan-tilt optical device executes step S130, it is also necessary to sample the ND filter adjustment parameters. After the pan-tilt optical device obtains the ND filter adjustment parameters according to the voltage adjustment parameters and the pulse width adjustment parameters, the pan-tilt optical device also samples the ND filter adjustment parameters. That is, after the pan-tilt optical device synthesizes the voltage pulse according to the voltage adjustment parameters and the pulse width adjustment parameters; the pan-tilt optical device also samples the voltage pulse; thereby obtaining the sampling parameters.

[0043] After the pan-tilt optical device obtains the sampling parameters, it is also necessary to convert the sampling parameters into signals. The pan-tilt optical device converts the sampling parameters into sampling signals. The transmittance adjustment signal may also include a target voltage pulse. The pan-tilt optical device first obtains the voltage pulse of the sampling signal from the sampling signal, and then obtains the target voltage pulse of the transmittance adjustment signal from the transmittance adjustment signal.

[0044] The voltage pulse used to adjust the transmittance of the ND filter is synthesized through voltage adjustment parameters and pulse width adjustment parameters; during the synthesis process, it may be affected by external factors, thereby affecting the accuracy of the synthesized voltage pulse. The pan-tilt optical device can compare the voltage pulse of the sampling signal with the target voltage pulse of the transmittance adjustment signal to determine whether the synthesized voltage pulse is consistent with the target voltage pulse of the transmittance adjustment signal, thereby obtaining a comparison result. If the voltage pulse of the sampling signal is consistent with the target voltage pulse of the transmittance adjustment signal, it means that there is no problem with the synthesized voltage pulse. If the voltage pulse of the sampling signal is inconsistent with the target voltage pulse of the transmittance adjustment signal, it means that there is a problem with the synthesized voltage pulse, and the pan-tilt optical device can synthesize the voltage pulse again according to the voltage adjustment parameters and pulse width adjustment parameters.

[0045] In some embodiments, the receiving of the transmittance adjustment signal in the foregoing step includes: Step S111, obtaining initial image data corresponding to the initial light transmittance; Step S112, sending the initial image data to the user terminal; Step S113, receiving a transmittance adjustment signal fed back by the user terminal according to the initial image data.

[0046] In this embodiment, refer to Figure 6When the pan-tilt optical device executes step S110, it receives the transmittance adjustment signal only after sending the initial image data corresponding to the initial transmittance to the user terminal. The pan-tilt optical device obtains the initial image data corresponding to the initial transmittance. Then the initial image data is sent to the user terminal. After the user terminal receives the initial image data, the user will determine whether the initial image data meets the standard through the user terminal. When the user determines that the initial image data does not meet the standard, the user can send a transmittance adjustment signal to the pan-tilt optical device through the user terminal; at this time, the pan-tilt optical device will receive the transmittance adjustment signal.

[0047] In some embodiments, the above-mentioned method of obtaining the neutral gray filter adjustment parameter according to the voltage adjustment parameter and the pulse width adjustment parameter includes: Step S131, generating a target voltage according to a voltage adjustment parameter; Step S132, generating a target pulse width according to the pulse width adjustment parameter; Step S133, synthesizing the target voltage and the target pulse width to obtain a neutral gray filter adjustment parameter.

[0048] In this embodiment, refer to Figure 7 After executing step S130, the pan-tilt optical device will generate a target voltage and a target pulse width. The pan-tilt optical device can generate a target voltage according to the voltage adjustment parameter; and generate a target pulse width according to the pulse width adjustment parameter. After obtaining the standard voltage and the target pulse width, the pan-tilt optical device can synthesize the target voltage and the target pulse width to obtain the ND filter adjustment parameter, that is, synthesize the target voltage and the target pulse width to obtain a voltage pulse.

[0049] The drone in the present invention directionally adjusts the transmittance of the neutral gray filter by receiving the transmittance adjustment signal sent by the user end; the user can remotely adjust the transmittance of the neutral gray filter in real time and accurately, thereby improving the efficiency and imaging quality of the drone's aerial photography operations, and enabling the drone to obtain high-quality image data under different light conditions.

[0050] The present invention also proposes a UAV gimbal optical transmittance adjustment system, the UAV gimbal optical transmittance adjustment system includes a UAV and a user end, and the UAV gimbal optical transmittance adjustment system can execute any of the UAV gimbal optical transmittance adjustment methods described above.

[0051] In this embodiment, refer to Figure 8 The optical transmittance adjustment system of the UAV gimbal includes a UAV and a user terminal. The user terminal can be used to control the UAV; and the UAV can be used to execute various control instructions sent by the user terminal.

[0052] In one embodiment, the drone includes a drone body and a gimbal optical device, the gimbal optical device includes a data processing module, a neutral gray filter adjustment module and an image acquisition module; the user end includes a transmittance adjustment module.

[0053] In this example, reference is made to Figure 8 The drone may include a drone body and a pan-tilt optical device; the drone body is used to load the pan-tilt optical device.

The user end may include a transmittance adjustment module, which may generate control parameters according to the user turning the hand wheel controller.

The memory 1005 may be a high-speed RAM memory, or a stable memory (non-volatile memory), such as a disk memory. The memory 1005 may also be a storage device independent of the aforementioned processor 1001.
