[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The portable high-precision mobile pan-tilt device comprises a quickly assembled guide rail adjustment base, a pan-tilt guide rail assembly, an image acquisition module and a calibration light control box. During the image acquisition process, according to the site requirements, appropriate and corresponding front left guide rails, front right guide rails, rear left guide rails and rear right guide rails are selected and assembled into corresponding guide rail lengths and shapes. Then, through the terminal control platform, the pan-tilt main body is quickly moved on the inner sides of the front left guide rail, the front right guide rail, the rear left guide rail and the rear right guide rail. During the movement or after moving to the designated position, the image acquisition device is controlled to acquire images. In a dark field environment, sufficient illumination is provided by the calibration light, thereby improving the efficiency and quality of image acquisition of the present invention.

[0023] 2. The portable high-precision mobile pan-tilt device, through the clamping of the reinforcement component, when the front left guide rail, the front right guide rail, the rear left guide rail and the rear right guide rail include curved rails, the guide rails formed by the front left guide rail, the front right guide rail, the rear left guide rail and the rear right guide rail are mixed with curved rails and straight rails, and the buffer guide wheel contacts the front left guide rail, the front right guide rail, the rear left guide rail and the rear right guide rail in priority to the guide wheel, and is deflected by the limit of the front left guide rail, the front right guide rail, the rear left guide rail and the rear right guide rail, and during the deflection At the same time, the friction between the buffer guide wheel and the front left guide rail, the front right guide rail, the rear left guide rail and the rear right guide rail is increased, and pre-deceleration is performed. At the same time, after the displacement sensor senses the displacement of the buffer guide wheel, it sends an electrical signal to the electric telescopic rod to control the electric telescopic rod to push out and then lock the buffer guide wheel, thereby further increasing the friction between the buffer guide wheel and the front left guide rail, the front right guide rail, the rear left guide rail and the rear right guide rail, reducing the inertia of the gimbal body and the image collector, and further improving the stability of the image collector during image acquisition.

[0024] 3. When the main body of the portable high-precision mobile pan-tilt device moves quickly outdoors, the wind force generated will affect the main body of the pan-tilt and the image collector, increasing the probability of the image collector shaking. At this time, the corresponding double-headed cylinder is controlled through the terminal control platform, and then the connecting seat and the support rod are driven to move outward by the double-headed cylinder, so that the support rod drives the folding wing plate to unfold, so that two adjacent folding wing plates are unfolded to a horizontal state, and then spliced ​​into an integral wing plate. Therefore, during the rapid movement of the pan-tilt main body, the wind force generates downward pressure under the influence of the folding wing plate, thereby improving the stability of the pan-tilt main body and the image collector during rapid movement.

[0058] See also Figure 10-13The reinforcement component 5 includes an external bracket 501, the internal part of the external bracket 501 is rotatably connected with a first bidirectional lead screw 502, and one end of the first bidirectional lead screw 502 passes through the external bracket 501, and the surfaces on both sides of the first bidirectional lead screw 502 are respectively threadedly connected with a first reinforcement bracket 503 and a second reinforcement bracket 504, the external bracket 501 is fixed to the surface of the pan / tilt body 301 through the first reinforcement bracket 503 and the second reinforcement bracket 504, the internal parts of the first reinforcement bracket 503 and the second reinforcement bracket 504 are both rotatably connected with a second bidirectional lead screw 505, and one end of the two second bidirectional lead screws 505 passes through the first reinforcement bracket 503 and the second reinforcement bracket 504 respectively, and the surfaces on both sides of the two second bidirectional lead screws 505 are threadedly connected with extension frames 506;

[0059] The bottom of the extension frame 506 is rotatably connected to a rotating base 507, a spring 508 is fixed on the top of the rotating base 507, one end of the spring 508 is fixed to the extension frame 506, a limit bracket 509 is fixed to the bottom of the rotating base 507, a buffer guide wheel 510 is rotatably connected to the middle of the limit bracket 509, a displacement sensor 511 is fixed on the surface of the rotating base 507, an electric telescopic rod 512 is fixed inside the limit bracket 509, and the output end of the electric telescopic rod 512 is located above the buffer guide wheel 510;

[0060] During the specific operation, based on the first embodiment, when the present invention is applied to outdoor scenes, the reinforcement component 5 can be installed on the outside of the pan-tilt body 301, that is, the first bidirectional screw 502 is rotated, and the first bidirectional screw 502 drives the first reinforcement bracket 503 and the second reinforcement bracket 504 to adjust in opposite directions, so that the external bracket 501 cooperates with the first reinforcement bracket 503 and the second reinforcement bracket 504 to be clamped and fixed on the outside of the pan-tilt body 301, thereby increasing the weight of the pan-tilt body 301, so that the center of gravity of the pan-tilt body 301 moves downward, thereby improving the stability of the pan-tilt body 301 when it moves quickly outdoors, reducing the influence of wind on the image collector 305, avoiding the image collector 305 from being shaken by wind when it moves quickly, thereby improving the image acquisition quality of the image collector 305;

[0061] At the same time, after the first reinforcement bracket 503 and the second reinforcement bracket 504 are installed, the second bidirectional screw 505 can be rotated, and the spacing of the extension bracket 506 can be adjusted by the second bidirectional screw 505, so that the extension bracket 506 drives the rotating base 507 and the limit bracket 509 to be clamped on the surfaces of the front left guide rail 206, the front right guide rail 207, the rear left guide rail 208 and the rear right guide rail 209, thereby improving the accuracy and stability of the installation of the first reinforcement bracket 503 and the second reinforcement bracket 504, and after the first reinforcement bracket 503 and the second reinforcement bracket 504 are installed, the buffer guide wheel 510 is correspondingly attached to the surfaces of the front left guide rail 206, the front right guide rail 207, the rear left guide rail 208 and the rear right guide rail 209, so that the buffer guide wheel 510 plays the role of a guide wheel;

[0062] Furthermore, in actual application, the front left guide rail 206, the front right guide rail 207, the rear left guide rail 208 and the rear right guide rail 209 may adopt curved rails, that is, the actual rails may be a mixture of straight rails and curved rails. When the front left guide rail 206, the front right guide rail 207, the rear left guide rail 208 and the rear right guide rail 209 are curved rails, during the rapid movement of the pan / tilt body 301, the buffer guide wheel 510 enters the curved rail section of the front left guide rail 206, the front right guide rail 207, the rear left guide rail 208 and the rear right guide rail 209 before the guide wheel 302. When the buffer guide wheel 510 enters the curved rail section, the buffer guide wheel 510 and the limiting bracket 509 are affected by the front left guide rail 206, The position limits of the front right guide rail 207, the rear left guide rail 208 and the rear right guide rail 209 are synchronously deflected following the deflection angles of the front left guide rail 206, the front right guide rail 207, the rear left guide rail 208 and the rear right guide rail 209. When the buffer guide wheel 510 deflects, the friction between the buffer guide wheel 510 and the front left guide rail 206, the front right guide rail 207, the rear left guide rail 208 and the rear right guide rail 209 increases, thereby playing a role in pre-deceleration of the pan-tilt body 301, thereby reducing the inertia of the pan-tilt body 301 after deceleration, and then reducing the inertia brought to the image collector 305 after the pan-tilt body 301 is decelerated, thereby improving the stability of image acquisition by the image collector 305;

[0063] Further, when the buffer guide wheel 510 enters the curved track section and is deflected by the front left guide rail 206, the front right guide rail 207, the rear left guide rail 208 and the rear right guide rail 209, the displacement sensor 511 senses the position offset and sends an electrical signal to the electric telescopic rod 512. At this time, the electric telescopic rod 512 is started after receiving the electrical signal, and is pushed outward after the electric telescopic rod 512 is started, so that the electric telescopic rod 512 contacts the buffer guide wheel 510, and then locks the buffer guide wheel 510, thereby further increasing the friction between the buffer guide wheel 510 and the front left guide rail 206, the front right guide rail 207, the rear left guide rail 208 and the rear right guide rail 209, and then pre-decelerates the gimbal body 301 again, reducing the inertia brought to the image collector 305 by the gimbal body 301, and once again improving the stability of image acquisition by the image collector 305;

[0064] When the buffer guide wheel 510 enters the straight rail section of the front left guide rail 206, the front right guide rail 207, the rear left guide rail 208 and the rear right guide rail 209 again, the buffer guide wheel 510 loses the limit of the front left guide rail 206, the front right guide rail 207, the rear left guide rail 208 and the rear right guide rail 209, and is reset under the pulling force of the spring 508, and continues to act as a guide wheel.

[0065] It should be noted that a slot is provided inside an extension frame 506 near the pan / tilt debugging interface 316 for matching the pan / tilt debugging interface 316 , thereby ensuring the accuracy of the installation of the reinforcement component 5 . Example

[0066] A double-headed cylinder 513 is fixed on the top of the first reinforcement bracket 503 and the second reinforcement bracket 504. A connecting seat 514 is fixed to the outside of the output shafts at both ends of the double-headed cylinder 513. A support rod 515 is fixed on the top of the connecting seat 514. A folding wing plate 516 is hinged on one side of the top of the support rod 515. Two adjacent folding wing plates 516 are connected by a connecting piece 517.

[0067] Specifically, when the present invention is applied to outdoor scenes, as the moving speed of the pan-tilt main body 301 increases, the impact of the wind on the pan-tilt main body 301 also increases, and the probability of shaking also increases. Therefore, when the present invention moves quickly outdoors to collect images, the corresponding double-headed cylinder 513 can be selected to start according to the moving direction of the pan-tilt main body 301, that is, when the moving direction of the pan-tilt main body 301 is from the second reinforcement bracket 504 to the first reinforcement bracket 503, the double-headed cylinder 513 on the top of the first reinforcement bracket 503 is started separately through the terminal control platform, so that the double-headed cylinder 513 drives the two connecting seats 514 to move outward. The connecting seat 514 drives the two support rods 515 to move outward. When the support rods 515 move outward, they drive the folding wing plates 516 to gradually unfold under the limit of the connecting piece 517 until the double-headed cylinder 513 is completely ejected, and the support rods 515 stop moving, that is, the two adjacent folding wing plates 516 are respectively unfolded under the drive of the two support rods 515 and spliced ​​into a complete wing plate. When the gimbal body 301 moves quickly, it is affected by the streamlined shell of the folding wing plates 516, that is, according to aerodynamics, the wind generates downward pressure when passing through the folding wing plates 516, thereby improving the stability of the gimbal body 301 and the image collector 305 when moving;

[0068] On the contrary, when the moving direction of the gimbal body 301 is from the first reinforcement bracket 503 to the second reinforcement bracket 504, the double-headed cylinder 513 on the top of the second reinforcement bracket 504 is started separately through the terminal control platform. Similar to the above steps, when the double-headed cylinder 513 is started, the support rod 515 is driven to link the folding wing plate 516 to unfold and splice into a complete wing plate, so that when the gimbal body 301 moves, the wind force passes through the folding wing plate 516 to generate downward pressure again, thereby improving the stability of the gimbal body 301 and the image collector 305 when moving, and further improving the quality of image acquisition when the gimbal body 301 and the image collector 305 move quickly outdoors.

[0069] It should be noted that the maximum stroke of the double-headed cylinder 513 corresponds to the unfolding spacing of the folding wing plates 516, that is, when the double-headed cylinder 513 reaches the maximum stroke, the two folding wing plates 516 are stretched to a horizontal state and the splicing is completed.
