Traditional object display methods mainly include physical display, flat picture display, video display, etc. However, these methods have the following problems: Physical display is intuitive, but it is not convenient in some occasions (such as large-scale exhibitions, remote displays, etc.). Currently, there are some three-dimensional display technologies on the market, such as virtual reality (VR), augmented reality (AR), and holographic projection. However, these technologies still have the following problems in practical applications: High equipment cost: VR / AR devices require high-performance computers, head-mounted devices, or other special hardware, and it is difficult to quickly deploy them on-site.

Since there is a certain gap between the third rod body 408 and the sliding sleeve 410, the structures such as the third rod body 408 cannot always be in an upright state, but will deflect slightly at the connection position of the first convex block 403 and the second convex block 405, which affects the final imaging effect on the display medium 201. With the cooperation of the arc-shaped plate 701 and the first stopper 404, the first rod body 401 can always be in a vertical position. It is convenient for the user to fix with the second bolt 409, and at the same time, it can avoid the situation that the display medium 201 is offset after the frame body 5 is fixed, ensuring normal imaging. The second stopper 715 is connected to the side of the back plate 703 away from the plate body 704, and the second stopper 715 is in contact with the rotating plate 702. The second stopper 715 can limit the rotating plate 702, restricting the rotating plate 702 to rotate counterclockwise only when in the vertical state, and then cooperating with the round roller 712 on the plate body 704 to drive the movement of the rotating plate 702.

[0034] In actual use, when the user lifts the frame 5 upward, the second spring 714 loses external support and begins to stretch, driving the slider 706 to move along the slide rail 707 in a direction away from the second spring 714. When the slider 706 moves, it drives the extension rod 708 and the first round wheel 709 to move, and the first round wheel 709 contacts the fan-shaped plate 710 and makes it rotate upward. At the same time, the slider 706 drives the plate body 704 to move through the connecting member 705, and the plate body 704 drives the round roller 712 to move in the slide groove 713 of the rotating plate 702 when moving, and the round roller 712 drives the rotating plate 702 to rotate, thereby making the arc plate 701 connected to the rotating plate 702 fit on the first rod body 401 and the second rod body 402 for limiting, so that the first rod body 401 is in an upright position, ensuring the clarity of the projection assembly 2 during imaging. The height of the sliding sleeve 410 is lower than the second rod 402. After the sliding sleeve 410 slides downward and is retracted, the frame 5 contacts the second round wheel 711 on the fan plate 710, and indirectly drives the slider 706 to move in the direction close to the second spring 714. The slider 706 drives the plate 704 to move through the connecting member 705. When the plate 704 moves, it drives the round roller 712 to move the rotating plate 702, thereby driving the arc plate 701 to separate from the first rod 401 and the second rod 402. At this time, the first rod 401 loses external force support, and the user can rotate the first rod 401 to a position parallel to the housing 1 for storage, which saves space when not in use and is easy to carry. The number of the auxiliary mechanism 4 and the linkage mechanism 7 can be two, which are arranged on both sides of the frame 5, and can further improve the stability of the display medium 201 when the frame 5 is pulled up.

[0035] When the frame 5 and the sliding sleeve 410 are pulled up, the arc plate 701 will first contact the sliding sleeve 410. As the sliding sleeve 410 continues to be pulled upward, the arc plate 701 will eventually contact the first rod body 401 and the second rod body 402 for position limiting. It is worth further explaining that in order to save production costs, the number of the auxiliary mechanism 4 and the linkage mechanism 7 can be one, but at the same time, in order to ensure the stability of the side of the display medium 201, the number of the auxiliary mechanism 4 and the linkage mechanism 7 can also be two. When the number of the auxiliary mechanism 4 and the linkage mechanism 7 is two, the two sets of auxiliary mechanisms 4 and the linkage mechanism 7 are staggered, which does not affect the lowering of the first rod body 401 for storage when the sliding sleeve 410 is sleeved on the second rod body 402. This method saves space when the system is not in use, and integrates all parts into one system to avoid loss during transportation.

[0036] In addition, another embodiment of the present invention further provides an article display method, which includes the following steps: placing the article to be displayed, placing the article to be displayed in the housing 301, ensuring that the article is placed stably and at the center of the shooting area; shooting the article to be displayed, the first camera 302 and the second camera 303 shoot the object in the housing 301, and the first motor 305, the first camera 302 and the second camera 303 are started. The first motor 305 drives the article to rotate, and the first camera 302 and the second camera 303 shoot different positions of the article. During the shooting process, the speed acquisition module monitors the frame rates of the first motor 305, the first camera 302 and the second camera 303 in real time and transmits them to the processor; processing the image data, obtaining the image data captured by the first camera 302 and the second camera 303 and performing preprocessing, and the preprocessing includes operations such as noise reduction, sharpening, and color correction. The processor also dynamically adjusts the shooting parameters according to the article complexity index; displaying the article, the images captured by the first camera 302 and the second camera 303 are processed by the processor and then displayed through the projection component 2.

[0037] This system realizes the rapid display of articles, facilitates direct operation on site, and does not require prior preparation. And the display method using three-dimensional images is more intuitive than traditional two-dimensional pictures, which is convenient for visitors to understand.

[0038] The step of displaying the article further includes: starting the second motor 601, the second motor 601 drives the third gear 602 to rotate clockwise, the third gear 602 meshes with the fourth gear 603 to rotate counterclockwise, the fourth gear 603 drives the shaft body 604 to rotate, the shaft body 604 drives the winding roller 605 to rotate, and the winding roller 605 pulls out the display medium 201 wound on the winding roller 605. At the same time, when the third gear 602 rotates, it will drive a plurality of cylinders 807 to rotate. When the cylinders 807 rotate, they will push the insertion rod 801 to rotate. When the insertion rod 801 rotates, it will disengage from the slot 806 on the frame 805. At this time, the user lifts the frame 5 upward. At this time, the second spring 714 loses the external force support and drives the slider 706 to move in a direction away from the second spring 714. When the slider 706 moves, it drives the extension rod 708 and the first round wheel 709 to move. The first round wheel 709 contacts the sector plate 710 and rotates upward. The slider 706 will also drive the plate body 704 to move through the connecting member 705. When the plate body 704 moves, it will drive the round roller 712 to move in the chute 713 of the rotating plate 702. At this time, the arc plate 701 connected to the rotating plate 702 fits on the first rod body 401 and the second rod body 402 for limiting, so that the first rod body 401 is in an upright position. The user can continue to pull up the sliding sleeve 410 and fix it on the third rod body 408 with the second bolt 409 to complete the unfolding of the display medium 201.

[0039] With the cooperation of the arc-shaped plate 701 and the first stopper 404, the first rod body 401 is always in a vertical position. This facilitates the user to fix it with the second bolt 409 and also avoids the deviation of the display medium 201 after the fixing of the frame body 5, ensuring normal imaging.

[0040] The steps of processing the image data further include: After analyzing the images captured by the first camera 302 and the second camera 303, the processor analyzes the complexity of the images and uses a complexity index to evaluate the complexity of the item to be displayed. Then, the processor dynamically adjusts the driving speed of the first motor 305 and the frame rates of the first camera 302 and the second camera 303. The processor calculates the complexity index of the item to be measured through the following formula: In this embodiment, the processor calculates the complexity index of the item to be measured through the following formula: According to the complexity index, the driving speed and the frame rate can be dynamically adjusted. The adjustment formula is as follows: 。

[0041] During actual use, assume: When the structure of the item to be measured is relatively simple, the processor increases the driving speed of the first motor 305 and the frame rates of the first camera 302 and the second camera 303 to shorten the display time; when the structure of the item to be measured is relatively complex, the processor decreases the driving speed of the first motor 305 and the frame rates of the first camera 302 and the second camera 303 to improve the quality of the final image.

[0042] In this embodiment, the calculation formula of the texture complexity is: The calculation formula of the edge density is: is the total edge length; S is the image area; The calculation formula for depth change is: The calculation formula for shape complexity is: C is the contour perimeter; A is the contour area.

[0043] In actual use, assume the item to be displayed is an apple: Regarding the calculation of texture complexity: Assume: The calculation of edge density: The calculation of depth change: Assume: The calculation of shape complexity: The calculation of complexity index: For complex items such as mechanical parts: The calculation of texture complexity: Assume: The calculation of edge density: The calculation of depth change: The calculation of shape complexity: Hypothesis: Calculation of complexity index: From the above two examples, it can be seen that: The complexity index C of the apple is 0.3, the driving speed and frame rate adjustment range are small, and the system operation efficiency is high.

[0044] The complexity index C of the mechanical part is 0.492, the driving speed and frame rate adjustment range are large, and the system imaging quality is higher.

[0045] The influence amplitude of different parameters can be achieved by adjusting the weight coefficient. The specific value of the weight coefficient is not limited and is determined according to the actual needs of the user.

[0046] The above specific implementation manners do not constitute a limitation to the protection scope of the present invention. Those skilled in the art should understand that various modifications, combinations, sub - combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
