Description

Technical Field

[0001] The present invention relates to the technical field of remote exhibitions, and specifically to an interactive three-dimensional panoramic exhibition method based on a physical exhibition hall. Background Art

[0002] Traditional physical exhibition halls usually rely on on-site visitors to directly view exhibits, which not only limits the audience scope of the exhibition, but may also cause potential damage to the exhibits due to too many visitors; in addition, on-site exhibitions often lack flexibility and interactivity, and are difficult to meet the personalized viewing needs of different audiences; with the development of technology, although some remote display and monitoring solutions have emerged, the remote viewing solutions often have a single function, cannot achieve all-round and multi-angle free control of exhibit display, and have limitations in remote control and automation; therefore, a new type of physical exhibition hall solution is needed to provide a more flexible, automated and intelligent three-dimensional panoramic exhibition experience while ensuring the safety of the exhibits and the efficiency of the display.

[0042] Embodiment 1

[0043] Please refer to Figure 13 As shown, the embodiment of the present application provides an interactive three-dimensional panoramic exhibition method based on a physical exhibition hall, which is applied to a physical exhibition hall device. The physical exhibition hall device includes an image acquisition device 11, an exhibition stand 1, and exhibits located in the exhibition stand. Specifically, it further includes the following steps:

[0044] S10. Establish a transmission channel remotely connected to the physical exhibition hall device, and use the display device 15 to access the transmission channel;

[0045] S20. Generate at least one movement control signal, change the positional relationship between the image acquisition device 11 and the exhibit 2 based on the movement control signal, and change the horizontal direction and height position of the image acquisition device 11 with respect to the exhibit 2.

[0046] When the physical exhibition hall and the display device 15 are in adjacent positions not in the same location, through the transmission channel, cooperate with the image acquisition device 11 to view the exhibit 2 in real time at a position far from the physical exhibition hall and the display device 15. For example, in a school, the display device 15 can be used to view the information of the exhibits 2 in the physical exhibition hall. Without a large number of students visiting the actual exhibition venue, the image acquisition device 11 can clearly and comprehensively display the position to be viewed while ensuring a better viewing distance, which not only protects the exhibited exhibits 2 but also improves the teaching and exhibition efficiency. In the state of being displayed by the display device 15, a movement control signal can be emitted by the display device 15 to adjust the image acquisition device 11 to generate a displacement in the corresponding direction according to the movement control signal, thereby achieving a highly flexible specified position observation effect.

[0047] As Figures 1 to 12 shown, implementing this three-dimensional panoramic exhibition method is based on a physical exhibition hall device, where the physical exhibition hall device includes: a protective frame 3, a steering drive mechanism 4, a rotating disk 5, a pushing device 6, a guiding mechanism 7, a suspension rod 8, and an adaptive adjustment mechanism 9. The protective frame 3 is arranged outside the exhibition stand 1, and the upper part of the protective frame 3 is located above the exhibit 2; the steering drive mechanism 4 is arranged on the protective frame 3; the rotating disk 5 is rotatably arranged on the protective frame 3 and is connected to the steering drive mechanism 4; the pushing device 6 is arranged on the rotating disk 5; the guiding mechanism 7 is arranged at the bottom end of the rotating disk 5 and is located on the side opposite to the pushing device 6; the suspension rod 8 is movably connected below the guiding mechanism 7; the adaptive adjustment mechanism 9 is connected between the suspension rod 8 and the guiding mechanism 7; wherein, the image acquisition device 11 is arranged at the bottom end of the suspension rod 8, the image acquisition device 11 can rotate omnidirectionally in the horizontal direction through the steering drive mechanism 4, the image acquisition device 11 can move to different height positions beside the exhibit 2 through the suspension rod 8 and the guiding mechanism 7, the orientation of the image acquisition device 11 is always located at the center point of the exhibit 2, and the transmission channel is used to transmit image information and movement control signals.

[0048] The physical exhibition hall device proposed in this application is a highly automated integrated device that provides all-round display and monitoring for the exhibit 2; the protective frame 3 is fixed to the outside of the exhibition stand 1 to provide physical protection for the exhibit 2 and a warning for the viewing distance of people around; the steering drive mechanism 4 is installed on the protective frame 3 and is responsible for driving the full-direction rotation of the rotating disk 5 in the horizontal direction; a pushing device 6 is installed on the rotating disk 5, which can push the image acquisition device 11 to move in the lateral direction of the exhibit 2; the guiding mechanism 7 is located at the bottom of the rotating disk 5 and is opposite to the pushing device 6 to ensure the stability and guiding property of the image acquisition device 11 during the movement; the hanging rod 8 is connected below the guiding mechanism 7 and can adjust the position of the image acquisition device 11 movably, while the adaptive adjustment mechanism 9 is connected to the hanging rod 8 and the guiding mechanism 7, allowing the hanging rod 8 to be finely adjusted at different heights to further adapt to the shape and size of the exhibit 2, so as to adaptively adjust the viewing distance between the image acquisition device 11 and the exhibits 2 of different volumes.

[0049] The image acquisition device 11 is installed at the bottom of the hanging rod 8 and can achieve full-direction rotation in the horizontal direction through the steering drive mechanism 4. At the same time, it can approach the exhibit 2 at different heights through the hanging rod 8 and the adaptive adjustment mechanism 9 to ensure that the orientation of the image acquisition device 11 always aligns with the center point of the exhibit 2; the transmission channel is responsible for transmitting image information and movement control signals to ensure that the image acquisition device 11 can efficiently and accurately capture and transmit the images of the exhibit 2; the entire device realizes an interactive three-dimensional panoramic exhibition method, making the viewing process an automated and intelligent display and monitoring, providing a richer and more dynamic display effect of the exhibit 2, while ensuring the safety of the exhibit 2 and the convenience of monitoring.

[0050] In addition, a display screen 151 is also provided on the display device provided in this application. The display screen 151 is used to display the image information obtained from the image acquisition device 11 and show it to the user, so that the user can view the better image information of the exhibit 2 through the display screen 151 without actually visiting the exhibition hall. In order to facilitate viewing the details of the exhibit 2 at different positions, an operation panel 152 or operation buttons are also provided on this display device, such as Figure 1, the shape of the operation panel 152 is circular, and it corresponds to multiple azimuth marks. For example, there are four prompt words "up", "down", "left", and "right" or marks indicating four directions. When the user observes the current displayed image, if they need to further observe the information on the left side, they can directly press the button corresponding to "left" or the operation panel 152, and then the display device 15 generates a control instruction for the steering drive mechanism 4. The control instruction is sent to the steering drive mechanism 4 through the transmission channel, and the steering drive mechanism 4 starts and drives the image acquisition device 11 to rotate around the exhibit 2 to the left. If the image acquisition device 11 needs to rotate to the right, it is the same principle to press the button corresponding to "right" or the operation panel 152; in addition, since the exhibit 2 is three-dimensional, the user also has the need to view the upper and lower parts of the side of the exhibit 2. Therefore, the user can also drive the image acquisition device 11 to move in the corresponding up and down directions by pressing the "up" or "down" position on the button or the operation panel 152. Different from the left and right movement directions of the image acquisition device 11, the up and down movement of the image acquisition device 11 is executed by the cooperation of the pushing device 6 and the guiding mechanism 7, indicating that the image acquisition device 11 moves in approximately two up and down directions on the guiding mechanism 7 to switch to the position that the user needs to view.

[0051] As Figure 3 shown, in some examples, further, the steering drive mechanism 4 includes: a drive motor 41, a worm gear 42, and a worm 43. The drive motor 41 is fixedly arranged at the top of the protective frame 3; the worm gear 42 is fixedly locked on the rotating disk 5 and is rotatably arranged in the middle of the top of the protective frame 3; the worm 43 is locked to the output end of the drive motor 41 through a coupling, and the worm 43 is meshed with the worm gear 42.

[0052] In this embodiment, the working principle of the steering drive mechanism 4 is that the drive motor 41 is fixed at the top of the protective frame 3, and with the locking connection structure between its output end and the worm 43 through a coupling, a stable transmission structure is formed; the worm gear 42 is fixedly locked on the rotating disk 5 and is located in the middle of the top of the protective frame 3 and can rotate; when the drive motor 41 starts, the power output by it is transmitted to the worm gear 42 through the worm 43, causing the worm gear 42 to rotate, and then driving the rotating disk 5 to rotate; the rotation in this process enables the exhibit 2 or the image acquisition device 11 installed on the rotating disk 5 to rotate in all directions in the horizontal direction, realizing the all-round display and monitoring of the exhibit 2; by precisely controlling the rotation angle of the rotating disk 5, it is ensured that the image acquisition device 11 can be aligned with the center point of the exhibit 2 to obtain high-quality image information; at the same time, through the display device 15, the speed regulation function of the drive motor 41 can be flexibly controlled, and the rotation speed of the rotating disk 5 can be adjusted to meet different display requirements.

[0053] As Figure 1 、 Figure 2 、Figure 5 , Figure 6 and Figure 11 As shown in Figure 5 , Figure 6 , and Figure 11 , in some examples, further, the pushing device 6 includes an electric push rod movably arranged below the rotating disk 5, and the electric push rod is further provided with: a pushing rotating block 61 and a fixed shaft 62. One end of the pushing rotating block 61 is fixedly connected to the telescopic end of the electric push rod, and the other end is rotatably arranged on the guiding mechanism 7. The fixed shaft 62 is fixedly arranged inside one end of the pushing rotating block 61 connected to the guiding mechanism 7. The fixed shaft 62 can rotate within the guiding mechanism 7, and a clamping gap 621 is further arranged inside the fixed shaft 62. A detachable connecting rope 12 is connected to the fixed shaft 62.

[0054] In this embodiment, the pushing device 6 realizes the moving function of the image acquisition device 11 in the side direction of the exhibit 2 through the telescopic action of the electric push rod. The image acquisition device 11 can move from the upper oblique side of the exhibit 2 to the side and the lower oblique side positions, so as to view the appearance of the exhibit 2 from multiple angles in one direction. Specifically, the electric push rod is movably arranged below the rotating disk 5, and its telescopic end is fixedly connected with the pushing rotating block 61. The fixed shaft 62 is fixedly arranged inside the pushing rotating block 61, and a clamping gap 621 is arranged inside the fixed shaft 62, allowing the clamping of the connecting rope 12. The connecting rope 12 can also be clamped at different length positions of the connecting rope 12 through the clamping gap 621 for use when matching exhibits 2 of different volumes.

[0055] As Figure 12 shown, it should be noted that when the electric push rod is in the retracted state, the inclination angle of the pushing rotating block 61 is A. After the electric push rod extends, due to the setting of the guiding mechanism 7, the angle of the electric push rod itself will also change during the telescopic process, which will drive the pushing rotating block 61 and the fixed shaft 62 inside it to rotate to the angle B. Through the difference between the angle B and the angle A, in this movement process, the end of the connecting rope 12 fixed to the fixed shaft 62 will also wind around the surface of the fixed shaft 62 by the difference angle between the angle B and the angle A. Therefore, the connecting rope 12 will be wound (or released) by a part. Furthermore, while changing the position of the image acquisition device 11 on the side of the exhibit 2 through the electric push rod, the effect of lifting or releasing the connecting rope 12 by winding the connecting rope 12 is used as the power to change the adaptive angle adjustment of the image acquisition device 11, so that when the image acquisition device 11 switches between different positions, it always faces the center position of the exhibit 2, and the picture displayed on the display device 15 is always the best-angle viewing picture.

[0056] As Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 11As shown, in some examples, further, the guiding mechanism 7 includes: a guiding track 71, a guiding groove 72, and a slider 73. The guiding track 71 is fixedly connected to the bottom end of the rotating disk 5, and the shape of the guiding track 71 corresponds to the outer contour shape of the exhibit 2; the guiding groove 72 is opened inside the guiding track 71; the slider 73 is slidably clamped in the guiding groove 72. The top end of the slider 73 is hinged to the fixed shaft 62 through a hinge seat, the bottom end of the slider 73 is connected with a suspension rod 8, and an adaptation adjustment mechanism 9 is connected to the side wall of the slider 73.

[0057] In this example, the guiding mechanism 7 of the device is composed of a guiding track 71, a guiding groove 72, and a slider 73. Its working principle is to utilize the guiding track 71 and the guiding groove 72 to provide a guiding path for the image acquisition device 11 at a position far above the exhibit 2. The shape of the guiding path corresponds to the outer contour shape of the exhibit 2, ensuring precise guidance when the exhibit 2 moves vertically, and during the movement, it fits the exhibit 2 as much as possible to maintain the best viewing distance. If the outer wall of the exhibit 2 is arc-shaped, the guiding groove 72 is also preferably set to be arc-shaped; the guiding groove 72 is opened inside the guiding track 71 to form a channel for the slider 73 to slide; the slider 73 can be clamped in the guiding groove 72, and its top end is hinged to the fixed shaft 62 through a hinge seat and thus connected to the telescopic end of the electric push rod. By starting the electric push rod, stable movement during the sideward movement of the exhibit 2 can be achieved. The bottom end of the slider 73 is connected with a suspension rod 8 for high-altitude suspension or the image acquisition device 11 to avoid blocking the actual visiting viewers below with an overly large structural area; an adaptation adjustment mechanism 9 is connected to the side wall of the slider 73, allowing fine adjustment of the position of the exhibit 2 or the image acquisition device 11 to adapt to the display requirements at different heights and angles; realizing precise positioning and display of the exhibit 2 in three-dimensional space.

[0058] As Figure 5 , Figure 6 and Figure 11 As shown, in some examples, further, the adaptation adjustment mechanism 9 includes: an inclined telescopic rod 91, a sliding ring 92, and a locking member 93. One end of the inclined telescopic rod 91 is fixedly connected to the side wall of the slider 73 through a hinge seat, and the other end of the inclined telescopic rod 91 extends towards the suspension rod 8; the sliding ring 92 is slidably sleeved on the outer wall of the suspension rod 8, and the slider 73 is rotationally connected to the other end of the inclined telescopic rod 91 through a hinge seat on the outer wall; the locking member 93 is arranged in the outer wall of the sliding ring 92. The locking member 93 can be a threaded rod screwed into the sliding ring 92, and by rotating the threaded rod, it firmly abuts against the outer wall of the suspension rod 8, so as to be able to position the positions of the slider 73, the inclined telescopic rod 91, and the suspension rod 8.

[0059] In this example, the adaptation and adjustment mechanism 9 of the device is fixedly connected to the side wall of the slider 73 through one end of the inclined telescopic rod 91, and the other end extends towards the boom 8 to adjust the position of the end of the bottom of the boom 8. Specifically, it is achieved by changing the inclination of the boom 8. Among them, the slip ring 92 can be sleeved on the outer wall of the boom 8 and slide, and is rotatably connected to the other end of the inclined telescopic rod 91 through the hinge seat on the outer wall. When the telescopic rod extends or contracts, due to the change in the length of the telescopic rod, the overall boom 8 rotates around the hinge seat at its top; in addition, the length of the telescopic rod can also be fixedly set, and the slip ring 92 is finely adjusted in the direction of the outer wall of the boom 8, thereby realizing another way of driving the boom 8 to rotate around the hinge seat at its top, and also realizing driving the position of the image acquisition device 11 to move in the direction of approaching or moving away from the exhibit 2. This solution does not make specific limitations in this regard. Therefore, through the above settings, the end of the bottom of the boom 8 can move, and the moving direction is the direction of approaching or moving away from the exhibit 2. After determining the moving position, the locking member 93 is arranged in the outer wall of the slider 73, which can accurately position and fix the positions of the slider 73, the inclined telescopic rod 91, and the boom 8, realizing the flexible displacement of the image acquisition device 11, being applicable for use during the exhibition of exhibits 2 of different sizes, with better flexibility, avoiding collision with the exhibit 2, and achieving the best display effect.

[0060] As Figure 5 , Figure 8 and Figure 11 shown, in some examples, furthermore, a height adjustment mechanism 10 is further provided between the boom 8 and the image acquisition device 11. The height adjustment mechanism 10 includes a telescopically inner tube 101 and a telescopically outer tube 102 that are relatively movably arranged. The height adjustment mechanism 10 is used to adjust the horizontal height of the image acquisition device 11.

[0061] In this example, the height adjustment mechanism 10 adjusts the horizontal height of the image acquisition device 11 through the relative movement of the telescopically inner tube 101 and the telescopically outer tube 102; the telescopically outer tube 102 is fixedly connected to the boom 8, while the telescopically inner tube 101 is connected to the image acquisition device 11; when it is necessary to adjust the height of the image acquisition device 11, the telescopically inner tube 101 and the telescopically outer tube 102 achieve height adjustment through their relative telescopic actions; the purpose is to ensure that the image acquisition device 11 can flexibly adjust its horizontal position according to the height of the exhibit 2 and the display requirements to obtain the best viewing angle and image quality; the operator adjusts the telescopic amount of the telescopically inner tube 101 and the telescopically outer tube 102 according to the display requirements, so that the image acquisition device 11 moves to an appropriate height in the vertical direction; adapting to the display requirements of exhibits 2 of different heights, obtaining high-quality image information, and further improving the flexibility of the device.

[0062] As Figure 3 , Figure 4 andFigure 6 As shown, in some examples, furthermore, the other end of the connecting rope 12 is internally connected to the end of the image acquisition device 11 via the slider 73, the hanging rod 8, and the height adjustment mechanism 10. The connecting rope 12 is used to change the rotation angle of the image acquisition device 11 following the rotation of the fixed shaft 62, so as to keep the image acquisition device 11 always facing the center position of the exhibit 2 at different height positions.

[0063] In this example, one of the solutions is provided, that is, a driving solution in which the connecting rope 12 drives the image acquisition device 11 to adaptively change the orientation angle following its own height change. Specifically, one end of the connecting rope 12 is fixed on the fixed shaft 62, and the other end is connected to the end of the image acquisition device 11. The rotation is carried out by using the angle change generated by the displacement of the fixed shaft 62 in the guiding mechanism 7, and the mechanism that the electric push rod drives the rotating block 61 to drive the fixed shaft 62 to rotate when it expands and contracts, so as to change the tension and length of the connecting rope 12, thereby adjusting the rotation angle of the image acquisition device 11; the purpose is to ensure that the image acquisition device 11 can always face the center position of the exhibit 2 at different heights and lateral positions, and no matter how the exhibit 2 or the image acquisition device 11 moves or adjusts the height, the best visual angle can be maintained to obtain high-quality images.

[0064] The working process principle is that when the electric push rod expands and contracts, the rotating block 61 is pushed to rotate accordingly, driving the fixed shaft 62 to rotate, and the connecting rope 12 is wound or released accordingly, adjusting the rotation angle of the image acquisition device 11 to adapt to different display requirements, ensuring that the picture displayed by the image acquisition device 11 is always the viewing picture at the best angle. If it is necessary to adjust the rotation speed of the graphic acquisition device during the displacement process, it can be achieved by replacing the fixed shaft 62 with different diameters.

[0065] As Figure 8 , Figure 9 and Figure 10 As shown, in some examples, furthermore, a rotating shaft 13 is also provided in the image acquisition device 11. One end of the rotating shaft 13 is provided with the end of the connecting rope 12 in a wound state, and a torsion spring 14 is provided at the other end of the rotating shaft 13. The connecting rope 12 is used to change the rotation angle of the image acquisition device 11 following the rotation of the fixed shaft 62, so as to keep the image acquisition device 11 always facing the center position of the exhibit 2 at different height positions.

[0066] Another solution is provided in this example. Different from the previous example, the working principle of this device is to set a rotating shaft 13 in the image acquisition device 11, set the end of the connecting rope 12 in a wound state at one end of the rotating shaft 13, and set a torsion spring 14 at the other end; when the fixed shaft 62 rotates in the guiding mechanism 7, the connecting rope 12 will be wound or released accordingly, driving the rotating shaft 13 to rotate, thereby changing the rotation angle of the image acquisition device 11; the role of the torsion spring 14 is to provide the necessary torque to help maintain the tension of the connecting rope 12 and ensure that the image acquisition device 11 can stably face the center of the exhibit 2; the purpose is to ensure that the image acquisition device 11 can always align with the center point of the exhibit 2 at different heights and positions, so as to obtain images with the best viewing angle.

[0067] The working process principle is that as the electric push rod expands and contracts, the propulsion rotating block 61 drives the fixed shaft 62 to rotate, and the connecting rope 12 is wound or released on the fixed shaft 62. Through the coordinated action of the rotating shaft 13 and the torsion spring 14, the rotation angle of the image acquisition device 11 is adjusted so that it always maintains alignment with the center of the exhibit 2 during the movement in the vertical and horizontal directions; when the image acquisition device 11 moves laterally, it can adaptively adjust its angle to ensure that the obtained image is always a display picture with the best viewing angle. If it is necessary to adjust the rotation speed of the graphic acquisition device during displacement, it can be achieved by replacing the rotating shaft 13 with different diameters or by other means of changing the surface diameter of the rotating shaft 13.

[0068] In some examples, further, any area of the inner track groove of the guiding track 71 is not collinear with the extension line formed by the expansion and contraction of the pushing device 6.

[0069] Specifically, precise guidance of the pushing device 6 is achieved through the guiding track 71 fixedly connected to the bottom end of the rotating disk 5 and the guiding groove 72 opened inside; the shape of the guiding track 71 corresponds to the outer contour shape of the exhibit 2 to ensure that the image acquisition device 11 can move along a predetermined path during movement; the shape of the guiding groove 72 can be a horizontal or inclined straight line, or an arc, or a combination of horizontal, inclined straight lines and arcs alternating. Such a design makes the pushing device 6 not collinear with the extension line of the guiding track 71 during the expansion and contraction process, that is, during the expansion and contraction process, through this non-collinear design, the pushing device 6 can move along more diverse paths, adapt to exhibits 2 with more complex outer surfaces, always maintain a relatively constant viewing distance from the exhibit 2, so that the image acquisition device 11 does not increase an additional autofocus burden during movement and always remains within the same focal length parameter. Even if the exhibit 2 changes rapidly, it can quickly and clearly feedback high-definition image information at close range, achieving a low-latency and efficient remote display effect.

[0070] In addition, when the electric push rod expands and contracts, due to the non-collinear design of the guiding groove 72 and the pushing device 6, during the movement of the slider 73, the pushing and rotating block 61 and the fixed shaft 62 can rotate accordingly, driving the connecting rope 12 to wind or unwind, thereby adjusting the rotation angle and position of the image acquisition device 11; enabling the image acquisition device 11 to observe and photograph the exhibit 2 at different angles and heights, and achieving a richer display effect.

[0071] In some examples, further, both the height adjustment mechanism 10 and the adaptation adjustment mechanism 9 include drive execution elements (not shown in the figure); an infrared distance sensor, a lighting device, and a controller (not shown in the figure) are also provided on the image acquisition device 11. The infrared distance sensor is connected to the controller, and the controller has limit distance threshold information built in; when the distance between the image acquisition device 11 and the exhibit 2 obtained by the infrared distance sensor is less than the limit distance threshold information, the controller controls that the instruction of the current movement control signal is not executed; or when the distance between the image acquisition device 11 and the exhibit 2 is less than the limit distance threshold information, the controller generates control instructions for the drive execution elements in the height adjustment mechanism 10 and the adaptation adjustment mechanism 9.

[0072] In this example, a control drive method for the image acquisition device 11 is further provided, which also has an active control function. The active control function depends on the controller. The controller can control the drive execution elements in the height adjustment mechanism 10 and the adaptation adjustment mechanism 9 to achieve precise positioning and position adaptive adjustment of the image acquisition device 11 in the vertical and horizontal directions. At the same time, the infrared distance sensor provided on the image acquisition device 11 is used to detect the distance from the exhibit 2; when the distance between the image acquisition device 11 and the exhibit 2 is less than the limit distance threshold built in the infrared distance sensor, the controller will react based on this information: one is not to execute the current movement control signal instruction to prevent the image acquisition device 11 from getting too close to the exhibit 2, thereby avoiding collision or interference; the other is to generate additional control instructions to activate the drive execution elements in the height adjustment mechanism 10 and the adaptation adjustment mechanism 9, and adjust the position of the image acquisition device 11 to ensure that it maintains a safe distance from the exhibit 2; and at the same time ensure that the distance between the exhibit 2 and the image acquisition device 11 is constant, thereby avoiding frequent focusing operations and additional waiting time caused by frequent changes in the distance parameter of the image acquisition device 11, and ensuring that the image acquisition device 11 can achieve the best shooting angle and distance when acquiring images, and at the same time avoid physical damage or interference to the exhibit 2;

[0073] The working process principle is that the controller monitors the distance between the image acquisition device 11 and the exhibit 2 in real time by connecting with the infrared distance sensor. Once it detects that the distance is too close, the controller will immediately respond and adjust the driving actuators of the height adjustment mechanism 10 and the adaptation adjustment mechanism 9 through control instructions to change the position of the image acquisition device 11, so as to maintain a safe and optimal shooting distance, avoid frequent adjustment of the focal length of the image acquisition device at close range, and achieve fast and high-quality image acquisition and display of the exhibit 2.
