DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] The core of the present invention is to provide a pan-tilt camera that can be used under different imaging conditions in all weather conditions and broaden the spectral observation range.

[0036] Please refer to Figures 1 to 6.

[0037] This specific embodiment discloses a pan-tilt camera, including an infrared module 1 and a pan-tilt device 2. As shown in Figure 5, the infrared module 1 includes an infrared lens 11 and an infrared movement 12. The infrared module 1 is used to acquire infrared images. The pan-tilt device 2 is provided with at least one rotatable motion component. The infrared module 1 is connected to the motion component, and the motion component is used to drive the infrared module 1 to move.

[0038] Preferably, the pan-tilt camera can be combined with infrared hotspot tracking technology to achieve target observation in low-light and complex environments.

[0039] Specifically, the infrared lens 11 can be manually adjusted. The infrared lens 11 is responsible for collecting infrared light within a focal length range of 10-15 mm, and the infrared core 12 is responsible for imaging the input 8-12 um long-wave infrared light.

[0040] During specific use, the pan-tilt device 2 can be used to control the movement of the infrared module 1 to adjust the imaging angle of the infrared module 1. It can be used under different imaging conditions in all weather conditions, broaden the spectral observation range, and the combination of the pan-tilt device 2 and the infrared module 1 solves the problem of infrared imaging stability, and can improve the shooting stability of the infrared module 1 during action to continuously output stable infrared images, avoiding the problem of having to use infrared equipment in a stationary and stable manner.

[0041] In one specific embodiment, the pan-tilt camera further includes a laser module 3 for emitting laser light. Laser module 3 is connected to the motion assembly and operates synchronously with infrared module 1. Specifically, laser module 3 and infrared module 1 can be configured as an integrated structure. During use, in the initial state, the relationship between the imaging of infrared module 1 and the direction of laser emission is adjusted. Subsequently, there is no need to adjust laser module 3 separately; the laser emission direction and the imaging of infrared module 1 can be adjusted synchronously, facilitating adjustment of the laser emission direction. Combining infrared module 1 and laser module 3 solves the problem of off-axis laser and infrared, while maintaining a stable state to avoid the problem of laser position shifting during motion.

[0042] Preferably, the laser module 3 includes a green laser for emitting green laser light. Compared with a general red laser light, the green laser light is easier to detect and has better visibility.

[0043] Specifically, the laser module 3 is responsible for outputting a green laser of 500-540 nm, with a coaxiality of at least 50 m and visibility within 100-150 m.

[0044] In a specific embodiment, as shown in Figure 1, the pan-tilt camera includes a first power member 21, a first connecting member 22, a second power member 23, a second connecting member 24, a third power member 25 and a wire hole 26. The wire hole 26 is used to pass the wire. One end of the first connecting member 22 is connected to the output end of the first power member 21, and the other end is fixedly connected to the second power member 23. One end of the second connecting member 24 is connected to the output end of the second power member 23, and the other end is fixedly connected to the third power member 25; the first power member 21 is used to drive the infrared module 1 to rotate around the first axis, the second power member 23 is used to drive the infrared module 1 to rotate around the second axis, and the third power member 25 is used to drive the infrared module 1 to rotate around the third axis. Any two of the first axis, the second axis and the third axis are perpendicular to each other.

[0045] Preferably, the first power member 21, the second power member 23, and the third power member 25 can all be set as servo motors for easy control; of course, the first power member 21, the second power member 23, and the third power member 25 can also be other power structures such as rotary cylinders and electric cylinders, which are determined according to actual conditions and will not be elaborated here.

[0046] As shown in Figure 1, the first axis is a vertical axis. The first power member 21 can drive the infrared module 1, the laser module 3, the second power member 23 and the third power member 25 to rotate around the first axis; the second power member 23 can drive the infrared module 1, the laser module 3 and the third power member 25 to roll around the second axis; the third power member 25 can drive the infrared module 1 and the laser module 3 to pitch around the third axis. Preferably, the first power component 21 can be set as an azimuth motor, the second power component 23 can be set as a roll motor, and the third power component 25 can be set as a pitch motor. The azimuth motor, roll motor, and pitch motor are connected through a mounting base and a rotating shaft. At the same time, the azimuth motor, roll motor, and pitch motor realize the control of the pan-tilt infrared module through a connecting mechanism; specifically, during actual use, the roll motor is responsible for realizing the roll flip of the pan-tilt module (0°~150°); the azimuth motor is responsible for realizing the azimuth change of the pan-tilt module (0°~360°); the pitch motor is responsible for realizing the pitch angle change of the pan-tilt module (-90°~90°); of course, it can also be other rotation angles, which are determined according to actual conditions.

[0047] Specifically, the rotation angle range of the first power member 21 can be 1° to 360°, and 360° rotation can be achieved in the circumferential direction; the rotation angle range of the second power member 23 is 0° to 150°, and the rotation angle of the third power member 25 is -90° to 90°. Of course, the first power member 21, the second power member 23, and the third power member 25 can also be other rotation angles, which are determined according to actual conditions and will not be elaborated here.

[0048] In this specific embodiment, the first power member 21, the second power member 23, and the third power member 25 drive the infrared module 1 and the laser module 3 to rotate as a whole, which can effectively improve the stability of the infrared module 1 and the laser module 3 and improve the imaging quality.

[0049] In a specific embodiment, the pan-tilt camera further includes an operating handle 4 , the pan-tilt device 2 is mounted on the operating handle 4 , and the operating handle 4 is provided with a control component, which is connected to both the pan-tilt device 2 and the infrared module 1 .

[0050] During actual use, the operating handle 4 can be held in hand to control the movement of the pan / tilt device 2 and the shooting of the infrared module 1 through the operation control component.

[0051] Preferably, the operating handle 4 is ergonomically designed and easy to grip.

[0052] Specifically, as shown in Figures 1 and 4, the control component includes an action button 61 and a shooting control button 62 arranged on the operating handle 4. The action button 61 is connected to the pan-tilt device 2 to control the pan-tilt device 2 to drive the infrared module 1 to move; the shooting control button 62 is connected to the infrared module 1 to control the infrared module 1 to shoot.

[0053] The operating handle 4 is arranged so as to be easy to grasp and convenient to use.

[0054] In Figures 1 and 4, the action button 61 is a five-way control button. By pressing different buttons of the five-way control button, the actions of different power parts in the pan-tilt device 2 can be controlled to realize the actions of the infrared module 1 and the laser module 3; for example, by pressing the up and down buttons in the five-way control button, the action of the third power part 25 can be controlled to drive the infrared module 1 and the laser module 3 to rotate as a whole around the third axis to realize pitch; by pressing the left and right buttons in the five-way control button, the action of the second power part 23 can be controlled to drive the infrared module 1 and the laser module 3 to rotate as a whole around the second axis to realize roll; by pressing the middle button in the five-way button, the action of the first power part 21 can be controlled to drive the infrared module 1 and the laser module 3 to rotate as a whole around the first axis to realize azimuth change.

[0055] As shown in FIG7 , an action remote sensing button 64 can be provided, and the action remote sensing button 64 is connected to the pan-tilt device 2 to control the pan-tilt device 2 to drive the infrared module 1 to move. Compared with other case forms, the action remote sensing button 64 in this specific embodiment has a better operational feel.

[0056] The power button 63 can be configured as the structure shown in FIG. 8 or as the structure shown in FIG. 2 , depending on the actual situation.

[0057] The shooting control button 62 is used to control quick functions such as shooting, recording, mode selection, and plan confirmation.

[0058] As shown in FIG2 , a power button 63 is provided on the side of the operating handle 4 , which can be used to control the power on and off of the pan / tilt camera.

[0059] In a specific embodiment, the operating handle 4 is provided with a display screen 5 that can rotate around different axes. The operating handle 4 is provided with a groove to accommodate the display screen 5. The display screen 5 can be rotated into the groove or rotated to be perpendicular to the operating handle 4.

[0060] As shown in Figure 2, the display screen 5 is rotated into the groove, and the outer surface of the display screen 5 is flush with the outer surface of the operating handle 4; as shown in Figure 1, the display screen 5 is rotatably set on the operating handle 4 through the flip axis 51, and the operating handle 4 can be rotated to the position shown in Figure 4 for easy observation.

[0061] Specifically, to flip from the state of Figure 2 to the state of Figure 4, the display screen 5 first needs to flip around the flip axis 51 to be perpendicular to the operating handle 4, and the display interface of the display screen 5 faces the bottom of the operating handle 4, and then the display screen 5 is controlled to rotate around another axis perpendicular to the flip axis 51 until it rotates to the state shown in Figure 4.

[0062] Preferably, the display screen 5 is a touch screen, and during use, the display status or shooting action of the display screen 5 can be controlled by touching; specifically, virtual buttons for controlling the action of the pan-tilt device 2 and the shooting action of the infrared module 1 can be set on the display screen 5.

[0063] In this specific embodiment, the display screen 5 is a large side-expanding screen, which can meet the user's observation needs and improve the user experience and effect.

[0064] As shown in FIG1 , an external threaded hole 41 is provided at the lower portion of the operating handle 4 , which can be used to connect to a structure such as a bracket to fix the pan / tilt camera.

[0065] In a specific embodiment, the operating handle 4 is provided with a storage card position and a data interface for an external storage card; as shown in Figure 2, the external storage card is a TF card position 72, to which an external TF card can be connected to expand the storage space to meet long-term recording needs and storage tasks; the data interface is a TYPE-C socket 71, which can provide complete TYPE-C protocol content to realize data content export and quick charging; of course, the storage card position and the data interface can also be other structural forms, which are determined according to actual conditions and will not be elaborated here.

[0066] It's important to note that the operating handle 4 houses a battery, motor control board, and main control board. The main control board is connected to the infrared module, laser module, display 5, control components, and motor control board. The battery powers the pan / tilt device 2, infrared module 1, and laser module 3, while the main control board facilitates the product's recording, shooting, image processing, function switching, and content storage functions. The main control board is screwed to the outer casing of the operating handle 4; the display 5's signal is connected to the main control board via a flexible flat cable to a coaxial cable.

[0067] The operating handle 4 may also be provided with indicator lights for displaying the remaining power and the remaining storage space, so as to facilitate real-time understanding of the remaining power and the remaining storage space.

[0068] In a specific embodiment, the gimbal camera also includes an adsorption fixing part, and the gimbal device 2 is installed on the adsorption fixing part. During use, the gimbal camera can be directly fixed by the adsorption fixing part; the adsorption fixing part can be a magnetic fixing part, an electrostatic adsorption fixing part, or a vacuum adsorption fixing part, and is used according to actual conditions.

[0069] For example, when cycling, the adsorption fixture can be attached to the vehicle body or to cycling equipment such as a hat to facilitate filming. When shooting stationary, the adsorption fixture can also be attached to a structure such as a table for fixation. The specific method depends on the actual situation and is not detailed here.
