Description

Technical Field

[0001] The present invention relates to the technical field of pan / tilt cameras, and in particular to a highly stable pan / tilt camera. Background Art

[0002] A PTZ camera is a camera with a pan / tilt head. The camera itself is able to rotate horizontally and vertically via a motor. Mounting the camera on a pan / tilt head can therefore expand the camera's viewing angle. The horizontal and vertical rotation angles can also be controlled by limit switches on the motors inside the pan / tilt head.

[0003] Among them, the gimbal camera mounted on the drone often needs to fly to high altitudes to form bird's-eye views and tracking images. However, since the wings rotate and generate airflow during the operation of the drone itself, the camera will be bumpy and the picture will shake. In addition, there are temperature changes during the change of the drone's altitude, which causes the camera lens to fog and reduce the clarity of the shooting picture. In addition, when the gimbal camera performs optical zoom to extend the lens, the center of gravity of the original camera will change. It needs to be leveled and calibrated after zooming to prevent the motor in the gimbal from maintaining the original leveling state, causing the picture to tilt downward and affecting the shooting effect. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems that the shooting picture of the pan-tilt camera mounted on the drone will be bumped and shaken due to the airflow generated by the rotation of the wings, and the temperature changes during the altitude change of the drone will cause the camera lens to fog and reduce the clarity of the shooting picture. When the pan-tilt camera performs optical zoom to extend the lens, the center of gravity of the original camera will change, and it is necessary to perform leveling calibration after zooming to avoid the motor in the pan-tilt to maintain the original leveling state, causing the picture to tilt downward and affecting the shooting effect. The present invention proposes a high-stability pan-tilt camera.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A highly stable pan-tilt camera includes a pan-tilt bracket for drone photography, the pan-tilt bracket controlling the pan-tilt state via pan-tilt motors in both horizontal and vertical directions, a zoom camera fixedly mounted on the bottom of the pan-tilt bracket, a stabilization unit disposed within the pan-tilt bracket for stabilizing images captured by the zoom camera, and the stabilization unit comprising a loading stabilization mechanism, a pan-tilt stabilization mechanism, and a shooting stabilization mechanism;

[0007] The loading stabilization mechanism includes a loading base arranged at the bottom of the pan / tilt bracket, a stabilization compensation base arranged on the top of the loading base, a leveling judgment module arranged on the top of the stabilization compensation base, a compensation slider arranged inside the stabilization compensation base, and a compensation stabilization ring arranged on the frame of the zoom lens of the zoom camera at the bottom of the compensation slider;

[0008] The pan / tilt stabilization mechanism includes a mounting bracket provided on the top of the pan / tilt bracket, the mounting bracket being provided with a reverse airflow compensation box located above the zoom camera lens, the reverse airflow compensation box being rotatably connected to two active airflow compensation fans arranged in front and behind, the two active airflow compensation fans being driven to rotate in opposite directions by two servo motors respectively provided on the sides of the reverse airflow compensation box;

[0009] The shooting stabilization mechanism includes a heating component arranged inside a compensation stabilization ring, and the compensation stabilization ring is connected to a reverse airflow offset box through a guide pipe.

[0010] Preferably, a grating capture transmitting end is provided on the top of the stable compensation seat, and the leveling judgment module is composed of a grating capture receiving end adapted to the grating capture transmitting end, a liquid leveling float and a leveling judgment box, and the grating capture receiving end is located below the liquid leveling float, and the leveling judgment module works when the UAV has no acceleration.

[0011] Preferably, a counterweight slider is movably connected inside the stable compensation seat, and the counterweight slider moves in opposite directions to the compensation slider through a matching gear.

[0012] Preferably, a counteracting hole and an airflow guiding groove are provided above the reverse airflow counteracting box, and a guide cover fixedly mounted on the outer surface of the mounting frame is provided at the bottom of the reverse airflow counteracting box.

[0013] Preferably, the two active airflow cancelling fans are symmetrically arranged, and the two servo motors control the two active airflow cancelling fans to rotate in opposite directions through a meshing gear set.

[0014] Preferably, a driven airflow cancelling fan is rotatably provided in the reverse airflow cancelling box, and the rotation of the driven airflow cancelling fan is driven by the counteracting airflow generated by the rotation of the active airflow cancelling fan.

[0015] Preferably, the guide tube consists of a reverse airflow compensation tube connected to the bottom of the reverse airflow compensation box, a movable closed tube and a negative pressure tube connected to the top of the compensation stabilization ring, and the reverse airflow compensation tube, the movable closed tube and the negative pressure tube are connected through a bend tube.

[0016] Preferably, a vortex airflow generating hole is provided in the compensation stabilization ring, and the vortex airflow generating hole is provided between the heating component and the zoom lens of the zoom camera.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The compensation stabilization ring equipped with a compensation slider is combined with the counterweight slider. When the zoom camera switches between short-focus and long-focus lenses, the counterweight slider can automatically offset the center of gravity changes caused by the optical zoom, so that the center of gravity remains at the initial center of gravity. This eliminates the need to repeatedly calibrate the center of gravity position of the zoom camera, increases the workload of the pan / tilt head electric leveling, and thus improves the leveling efficiency of the pan / tilt head motor.

[0019] 2. By coordinating the leveling judgment module with the grating capture transmitter, the range of movement of the liquid leveling float in the leveling judgment module is limited based on the light refraction angle, that is, the tilt angle of the stable compensation seat is limited. Therefore, during the process of offsetting the center of gravity of the zoom camera, whether there is any obstruction of the grating infrared light can be used to quickly determine whether the pan-tilt camera maintains a horizontal state during the leveling process, and timely remind staff to replace excessively worn counterweight sliders.

[0020] 3. By using the reverse airflow cancellation box equipped with active airflow cancellation fans and driven airflow cancellation fans in conjunction with the guide cover, an upward airflow can be generated to offset the downward airflow during the flight of the drone, reducing the resulting turbulence and achieving the purpose of improving the shooting stability of the zoom camera.

[0021] 4. By combining the compensating stabilizing ring with the heating component and the reverse airflow offset box, when water mist appears on the camera screen, the heating component can be turned on to form a vortex airflow that is evenly distributed on the lens surface of the zoom camera. This allows the lens to be evenly heated while removing dust on the surface, providing protection for the zoom camera. This achieves the purpose of active defogging for the zoom camera while extending its service life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "mounted / connected," and "connected" should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention in specific circumstances.

[0034] Example, see Figures 1 to 8 A high-stability pan-tilt camera includes a pan-tilt bracket 1 for drone photography. The pan-tilt bracket 1 controls the pan-tilt state through pan-tilt motors in both horizontal and vertical directions. A zoom camera 2 is fixedly mounted on the bottom of the pan-tilt bracket 1. A stabilization unit is provided in the pan-tilt bracket 1. The stabilization unit is used to stabilize the image captured by the zoom camera 2. The stabilization unit is composed of a loading stabilization mechanism, a pan-tilt stabilization mechanism, and a shooting stabilization mechanism.

[0035] It should be noted that the pan-tilt camera used in this application is a conventional optical zoom camera 2. By fixing the zoom camera 2 to the bottom of the pan-tilt bracket 1 and starting the pan-tilt motor, the camera angle of the zoom camera 2 can be automatically adjusted. This is a prior art and will not be described in detail in the subsequent description.

[0036] Based on the above, the stabilization unit can adjust the camera center of gravity of the zoom camera 2 during the zooming process by loading a stabilization mechanism to ensure its loading stability; then the pan-tilt stabilization mechanism can generate a reverse offsetting airflow to offset the airflow generated by the drone flying on the top of the zoom camera 2, reducing the interference of the downward airflow on the camera image of the zoom camera 2; during this period, the shooting stabilization mechanism can remove the water mist phenomenon that appears on the lens of the zoom camera 2 due to temperature changes during the lifting process, thereby providing a highly stable shooting environment for the zoom camera 2.

[0037] like Figure 4 and Figure 5 As shown, the loading stabilization mechanism includes a loading base 3 arranged at the bottom of the pan-tilt bracket 1, a stabilization compensation seat 31 is arranged on the top of the loading base 3, a leveling judgment module 32 is arranged on the top of the stabilization compensation seat 31, a compensation slider 33 is arranged inside the stabilization compensation seat 31, and a compensation stabilization ring 5 is arranged on the zoom lens frame of the zoom camera 2 at the bottom of the compensation slider 33.

[0038] It should be noted that the zoom camera 2 is located below the loading base 3 and is installed by fixing bolts or clamping devices. The leveling judgment module 32 is set on the top of the loading base 3. It judges whether the zoom camera 2 is level when the drone is stationary, hovering, or traveling at a constant speed, and compensates for the center of gravity change caused by the lens during the zoom process through the compensation slider 33.

[0039] Furthermore, a grating capture transmitting end is provided on the top of the stabilization compensation seat 31, and the leveling judgment module 32 is composed of a grating capture receiving end 321 adapted to the grating capture transmitting end, a liquid leveling float 322 and a leveling judgment box 323, and the grating capture receiving end 321 is located below the liquid leveling float 322. The leveling judgment module 32 works when the UAV has no acceleration, that is, when the UAV is in a stationary, hovering and uniform speed state without weightlessness or overweight.

[0040] It should be noted that: based on the grating capture principle, after the zoom camera 2 is installed on the bottom of the stable compensation seat 31, infrared light is emitted by the grating capture transmitting end and received by the grating capture receiving end 321, completing the signal receiving operation of the leveling judgment module 32, and the diameter range set by the two is used as the activity range of the liquid leveling float 322. When the zoom camera 2 is tilted, the liquid leveling float 322 will move out of this activity range, blocking the infrared light, that is, the zoom camera 2 is not in a horizontal state at this time, so that it can be easily judged whether the pan-tilt camera maintains a horizontal state during the leveling process, and timely remind the staff to replace the excessively worn counterweight slider 34;

[0041] Furthermore, the internal movably connected stabilizing and compensating seat 31 is provided with a counterweight slider 34, which moves in opposite directions from the compensating slider 33 through the mating gear 341, and the mating gear 341 is rotatably arranged inside the stabilizing and compensating seat 31, and meshes with the rack arranged on the opposite side of the counterweight slider 34 and the compensating slider 33.

[0042] It should be noted that: Figure 6 As shown, when the lens of the zoom camera 2 performs optical zoom, the lens will be displaced relative to the mounting portion of the zoom camera 2. At this time, the compensating stabilizing ring 5 is mounted on the zoom lens, which can reversely drive the mating gear 341, driving the counterweight slider 34 to move in the opposite direction, thereby offsetting the center of gravity shift of the zoom camera 2 during long-focus shooting, so that the center of gravity of the zoom camera 2 remains at the initial center of gravity. Similarly, when the zoom camera 2 performs short-focus shooting, the center of gravity is adjusted by the counterweight slider 34, so that the center of gravity remains at the initial center of gravity, thereby automatically offsetting the center of gravity change caused by the optical zoom of the zoom camera 2. There is no need to repeatedly calibrate the center of gravity position of the zoom camera 2, which increases the leveling workload of the pan / tilt motor, thereby improving the leveling efficiency of the pan / tilt motor.

[0043] Based on the above, if Figure 6 As shown, the counterweights of the counterweight slider 34 and the compensation slider 33 are relatively arranged on the left and right sides, and the meshing parts of the two and the matching gear 341 are hollowed out, which will not affect the change of the center of gravity of the stable compensation seat 31, and the weight of the counterweight of the counterweight slider 34 is equal to the weight of the counterweight of the compensation slider 33 plus the weight of the zoom camera 2. Therefore, when the compensation slider 33 and the counterweight slider 34 move equidistantly, the initial center of gravity of the stable compensation seat 31 is not changed, so that when the compensation slider 33 drives the matching gear 341 to rotate, the sliding counterweight slider 34 can offset the change in the center of gravity caused by the change in the focal length of the zoom lens.

[0044] like Figure 7 As shown, the pan-tilt stabilization mechanism includes a mounting bracket 4 arranged on the top of the pan-tilt bracket 1, and the mounting bracket 4 is provided with a reverse airflow compensation box 41 above the lens part of the zoom camera 2. Two active airflow compensation fans 42 arranged in front and behind are rotatably connected in the reverse airflow compensation box 41. The two active airflow compensation fans 42 are respectively driven by two servo motors 43 arranged on the sides of the reverse airflow compensation box 41 to rotate in opposite directions.

[0045] It should be noted that: during the shooting process of the zoom camera 2, the active airflow compensation fan 42 is driven to rotate by the servo motor 43, an airflow in the opposite direction is generated on the top of the reverse airflow compensation box 41, and the downward blowing airflow is driven outward, thereby reducing the interference of the downward blowing airflow on the shooting of the zoom camera 2.

[0046] Furthermore, a compensation hole 411 and an airflow guide groove 412 are provided above the reverse airflow compensation box 41, and a guide cover 413 fixedly installed on the outer surface of the mounting frame 4 is provided at the bottom of the reverse airflow compensation box 41, so that the airflow on the surface of the guide cover 413 can be accelerated to flow outward on the upper side of the reverse airflow compensation box 41, and generated by the rotation of the active airflow compensation fan 42. The two active airflow compensation fans 42 are symmetrically arranged, and the two servo motors 43 control the two active airflow compensation fans 42 to rotate in opposite directions through the meshing gear set 431.

[0047] It should be noted that an air circulation space is provided in the central area of ​​the reverse airflow offset box 41. During the reverse rotation of the active airflow offset fan 42, an upward airflow can be generated in the air circulation space through the active airflow offset fan 42, and this airflow, i.e., the reverse airflow, can offset the downward airflow generated during the flight of the drone, and at the airflow guide groove 412, the air flow at the top of the deflection cover 413 is accelerated, so that the downward blowing airflow flows to a farther distance through the deflection cover 413, thereby improving the stability of the gimbal bracket 1 during shooting and improving the shooting quality.

[0048] Based on the above, a driven airflow cancelling fan 44 is rotatably provided in the reverse airflow cancelling box 41, and the rotation of the driven airflow cancelling fan 44 is driven by the rotation of the active airflow cancelling fan 42 to generate a cancelling airflow;

[0049] It should be noted that: when the active airflow canceling fan 42 rotates, the generated canceling airflow can drive more driven airflow canceling fans 44 to rotate, and accelerate and disperse the downward airflow generated by the drone in multiple directions, avoiding the downward airflow directly acting on the pan-tilt part of the zoom camera 2, thereby enhancing the reverse airflow canceling box 41's ability to offset the drone's flying airflow.

[0050] like Figure 8 As shown, the shooting stabilization mechanism includes a heating component arranged inside the compensation stabilization ring 5, the compensation stabilization ring 5 is connected to the reverse airflow compensation box 41 through the guide tube 51, and a vortex airflow generating hole 52 is provided in the compensation stabilization ring 5, and the vortex airflow generating hole 52 is provided between the heating component and the zoom lens of the zoom camera 2.

[0051] It should be noted that when the reverse airflow offset box 41 generates an upward airflow driving force, it guides the airflow in the guide tube 51, generating a reverse airflow passing through the heating component. When water mist appears on the camera screen, the remote control is manually controlled to turn on the existing heating component, such as an electric heating coil, to heat the airflow and accelerate the evaporation of the water mist, thereby achieving the purpose of actively defogging the zoom camera 2.

[0052] Based on the above, if Figure 7 The airflow path is shown in FIG, wherein the single dashed line and the guide arrow are the offset airflow generated by the reverse airflow offset box 41 and its flow direction, and the double dashed line and the guide arrow are the airflow generated downward by the drone and the flow direction of the passive airflow after being guided by the guide cover 413 and the airflow;

[0053] Based on the above, the two servo motors 43 provided on the front and rear sides respectively drive the active airflow canceling fan 42 to rotate in opposite directions, thereby generating an offset airflow surging upward, and drive the driven airflow canceling fans 44 provided on the left and right sides to rotate synchronously, thereby forming Figure 7 The offsetting airflow of the single dashed line flow is shown in ;

[0054] A further advantage of adopting the above method is that when the negative pressure inside the guide tube 51 generates suction on the vortex airflow generating hole 52, it drives the external air to form a vortex airflow, so that the heated airflow can be evenly spread on the lens surface of the zoom camera 2, so that the lens is evenly heated, thereby providing protection for the zoom camera 2 and extending its service life.

[0055] Furthermore, the guide pipe 51 is composed of a reverse airflow compensation pipe 511 connected to the bottom of the reverse airflow compensation box 41, a movable closed pipe 512 and a negative pressure pipe 513 connected to the top of the compensation stabilization ring 5, and the reverse airflow compensation pipe 511, the movable closed pipe 512 and the negative pressure pipe 513 are connected by a bent pipe.

[0056] It should be noted that: when the compensation stabilization ring 5 moves with the zoom lens, the movable sealing tube 512 can ensure the connection between the reverse airflow compensation tube 511 and the negative pressure tube 513, so that there is always a vortex negative pressure airflow in the compensation stabilization ring 5, and the lens surface is dust-removed to prevent dust from adhering to the lens surface and affecting the shooting effect.

[0057] Working principle:

[0058] When improving the shooting stability of the zoom camera 2, the present invention is divided into three processes: center of gravity compensation stabilization of the zoom camera 2, pan-tilt airflow offset stabilization and water mist dust removal stabilization. Among them, the center of gravity compensation stabilization process of the zoom camera 2 is: after the zoom camera 2 is loaded on the bottom of the pan-tilt bracket 1, the compensation stabilization ring 5 is sleeved on the zoom lens frame of the zoom camera 2, and moves with the lens change, thereby driving the compensation slider 33 to move synchronously, so that the counterweight slider 34 is opposite to the movement direction of the lens, so that the center of gravity of the zoom camera 2 is maintained at the initial center of gravity when switching between the short-focus lens and the long-focus lens for shooting, automatically offsetting the center of gravity change caused by the optical zoom of the zoom camera 2, and there is no need to repeatedly calibrate the center of gravity position of the zoom camera 2 to increase the leveling workload of the pan-tilt motor, thereby improving the leveling efficiency of the pan-tilt motor.

[0059] Based on the above, the process of stabilizing the pan / tilt airflow compensation of the zoom camera 2 is as follows: when the drone's fan blades rotate and generate a downward airflow to the pan / tilt, the servo motor 43 is started to drive the active airflow compensation fan 42 to rotate, thereby causing the reverse airflow compensation box 41 to generate an upward compensation airflow, thereby reducing the interference of the downward airflow on the zoom camera 2.

[0060] Based on the above, further, at the air flow guide groove 412, the air flow on the top of the deflection cover 413 is accelerated, so that the downward air flow flows to a farther distance through the deflection cover 413, and by setting a driven air flow offset fan 44, the downward air flow generated by the drone can be accelerated and dispersed in multiple directions, avoiding the downward air flow directly acting on the gimbal part of the zoom camera 2, thereby improving the stability of the gimbal bracket 1 during shooting and improving the shooting quality.

[0061] Based on the above, the stabilization process of the water mist dust removal for the zoom camera 2 is as follows: when the reverse airflow offset box 41 generates an upward airflow driving force, it guides the airflow in the guide tube 51, generating a reverse airflow passing through the heating component. When the lens temperature deviates due to the drone's lifting and lowering in the camera image, causing water mist to condense, the existing heating component is turned on to heat the airflow, accelerate the evaporation of the water mist, and achieve the purpose of active defogging for the zoom camera 2;

[0062] Based on the above, when the negative pressure inside the guide tube 51 generates suction on the vortex airflow generating hole 52, it drives the external air to form a vortex airflow, so that the heated airflow can be evenly spread on the lens surface of the zoom camera 2, so that the lens is evenly heated, thereby providing protection for the zoom camera 2 and extending its service life.

[0063] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
