Description

Technical Field

[0001] The present invention relates to the field of virtual imaging, and in particular to an AR display method based on Internet of Things imaging. Background Art

[0002] AR is an improved technology based on virtual reality, which can superimpose the real scene and the virtual scene in real time, provide a more realistic scene for users, and further enhance the user's immersion.

[0003] In the virtual scene of AR, the simulation degree of the scene is related to the user experience. Among the simulation degrees of the scene, the number of objects and the imaging quality are crucial. Among them, the number of objects can be increased by adding database inventory for materials to be called during use. For the imaging quality, the most important thing is the modeling of real objects.

[0004] In the modeling of objects, it is necessary to scan the objects to obtain the three-dimensional data of the objects. And to ensure the scanning accuracy, at present, the scanning of objects basically uses a circumferential scanning device. By making the scanning device move in a circular motion, the objects are scanned at equal distances to ensure the imaging effect.

[0005] However, the existing object scanning devices lack a necessary device for positioning the objects, making it difficult to move in a circular motion with the object as the center when the scanning device moves in a circular motion. Therefore, when the scanning device moves in a circular motion, the distances between the scanning device and the objects are actually inconsistent, affecting the scanning accuracy.

[0045] In the embodiment of the present invention, an AR display method based on Internet of Things imaging includes the following steps:

[0046] Step 1: Place the object to be three-dimensionally modeled in the image acquisition device, and the image acquisition device can fix the object and position the object.

[0047] Step 2: After the object is fixed, the image acquisition device performs a spiral scan on the external features of the object and stores the scanned information.

[0048] Step 3: Send the collected information to the information synthesis device, and the information synthesis device models the three-dimensional model of the object according to the information collected by the image acquisition device and stores the generated three-dimensional model in the virtual image storage library.

[0049] Step 4: Connect the AR imaging device to the virtual avatar repository to enable communication between the AR imaging device and the virtual avatar repository. The AR imaging device can call the 3D models in the virtual avatar repository by reading user instructions and display them.

[0050] Please refer to Figures 1 to 8 , wherein the image acquisition device includes: a base 1, a positioning component, and a spiral acquisition mechanism.

[0051] A receiving tray 3 is fixedly installed on the base 1;

[0052] The positioning component is arranged on the base 1 and is used to fix an object. It includes an elastic support structure and a multi-directional driving structure. The multi-directional driving structure is connected to a plurality of abutting rods 10 arranged on the receiving tray 3. When the object is placed on the elastic support structure, the multi-directional driving structure acts and drives the plurality of abutting rods 10 to move closer to each other;

[0053] The elastic support structure includes a fixed sleeve 2 connecting the receiving tray 3 and the base 1 and a butting shaft 5 passing through the receiving tray 3 and extending into the interior of the fixed sleeve 2. A plurality of balls are arranged at the upper end of the butting shaft 5. A plurality of equally divided parts 6 penetrating the fixed sleeve 2 are symmetrically installed at the lower end of the butting shaft 5. A protrusion 7 is fixedly installed at one end of the equally divided part 6 away from the butting shaft 5;

[0054] A spring 4 is further arranged in the fixed sleeve 2. One end of the spring 4 is connected to the receiving tray 3, and the other end is connected to the butting shaft 5;

[0055] The multi-directional driving structure includes a plurality of sliding grooves 8 arranged at equal circumferential intervals on the receiving tray 3. A slider 9 is slidably installed in the sliding groove 8. The slider 9 is connected to the abutting rod 10, and a guiding plate 11 is fixedly installed on the slider 9. An inclined groove 12 is arranged on the guiding plate 11, and the protrusion 7 can slide in the inclined groove 12.

[0056] In the initial state, that is, when no object is placed, under the action of the spring 4 at this time, the abutting shaft 5 is in an upwardly jacked state. At this time, the protrusion 7 at the end of the equalizing member 6 connected to the abutting shaft 5 is at one end of the inclined groove 12. At the same time, the plurality of abutting rods 10 are in a separated state from each other. At the same time, in this state, the height of the abutting shaft 5 is the same as the height of the abutting rods 10. When an object is placed on the abutting shaft 5, under the action of the gravity of the object, the abutting shaft 5 is driven to move downward, compressing the spring 4. At the same time, the protrusion 7 follows the equalizing member 6 to move downward. At this time, the protrusion 7 is in sliding fit with the inclined groove 12, and the guide plate 11 is driven to move, and the slider 9 is driven to move along the length direction of the sliding groove 8, so that the plurality of abutting rods 10 move closer to each other, thereby clamping the periphery of the object. And because there are balls provided on the abutting shaft 5, when the object is not at the center of the receiving tray 3, under the action of the plurality of abutting rods 10, the object can be moved to the center position of the receiving tray 3, thereby realizing positioning, so that in the subsequent scanning process, the obtained image information is more accurate.

[0057] Through the above settings, the automatic clamping of the object is realized, and the heavier the object is, the greater the clamping force is, thereby improving the clamping force on the object with a larger weight and ensuring the stability of the object during image acquisition. At the same time, since the plurality of abutting rods 10 move at the same speed, when the abutting rods 10 abut against the object, the object can be pushed towards the center of the receiving tray 3, thereby realizing automatic positioning, so that during image information acquisition, the distance between the object and the scanning device 32 is more constant, thus ensuring the scanning effect.

[0058] It should be noted that in order to ensure the scanning effect, this image acquisition device is only applicable to scanning regular polyhedron objects such as cylinders and cubes.

[0059] Please refer to Figure 5 、 Figure 7 、 Figure 8 The spiral acquisition mechanism is arranged on the base 1 and is used for acquiring the external features of the object. The spiral acquisition mechanism includes a rotating component and a lifting component which are linked. A scanning device 32 is connected to the lifting component. When the rotating component acts, the lifting component rotates following the rotating component, and the lifting component can drive the scanning device 32 to lift intermittently;

[0060] The rotating component includes a driving device 13 fixedly installed on the receiving tray 3. The output shaft of the driving device 13 is connected by a first belt 14 to a rotating sleeve 15 which is rotatably installed on the receiving tray 3 and is coaxially arranged with the fixed sleeve 2. One end of the rotating sleeve 15 away from the receiving tray 3 is connected with a telescopic plate member;

[0061] One end of the telescopic plate member away from the rotary sleeve 15 is fixedly provided with a mounting plate 18, and the mounting plate 18 is connected to the lifting assembly;

[0062] The telescopic plate member includes a rotary sleeve plate 16 fixedly installed on the rotary sleeve 15. A telescopic plate 17 is slidably installed on the rotary sleeve plate 16, and the rotary sleeve plate 16 and the telescopic plate 17 are connected by an electric push rod 19;

[0063] The telescopic plate 17 is fixedly connected to the mounting plate 18.

[0064] During use, by controlling the driving device 13 to work, the rotary sleeve 15 can be driven to rotate, and the rotary sleeve plate 16 connected to the rotary sleeve 15 can make a circular motion, so that the telescopic plate 17 makes a circular motion, thereby driving the scanning device 32 to make a circular motion with the object as the center and collecting the external features of the object.

[0065] Furthermore, when scanning a cylindrical object, if the diameter of the object is small, after the object is clamped and positioned, the distance between the scanning device 32 and the object can be changed by controlling the electric push rod 19, so that the distance between the scanning device 32 and the object is smaller and the scanning accuracy is better.

[0066] Please refer to Figure 3 、 Figure 7 、 Figure 8 The rotary assembly further includes a telescopic transmission structure disposed between the fixed sleeve 2 and the mounting plate 18. The telescopic transmission structure includes a bevel gear set 20 installed between the rotary sleeve plate 16 and the fixed sleeve 2. The bevel gear set 20 is connected to a transmission rod 21 rotatably installed on the rotary sleeve plate 16. The transmission rod 21 is sleeved inside a driven shaft 22, and the driven shaft 22 is connected to the lifting assembly through a second belt 23;

[0067] A limiting groove is formed on the inner wall of the transmission rod 21, and the limiting groove is slidably matched with a limiting block disposed on the outer wall of the driven shaft 22;

[0068] The bevel gear set 20 includes a first bevel gear coaxially connected to the fixed sleeve 2 and a second bevel gear meshing with the first bevel gear and rotatably installed on the rotary sleeve plate 16;

[0069] The lifting assembly includes two transmission wheels 26 rotatably installed on the mounting plate 18, and a transmission belt 27 is sleeved between the two transmission wheels 26;

[0070] The lifting assembly further includes vertical grooves 30 symmetrically arranged on both sides of the mounting plate 18. A lifting member 29 connected to the scanning device 32 is slidably mounted in the vertical grooves 30. A fitting groove 31 is formed in the lifting member 29, and a fitting block 28 rotatably mounted on the transmission belt 27 can slide in the fitting groove 31;

[0071] The rotating shaft of one of the transmission wheels 26 is connected to a Maltese cross mechanism structure arranged on the mounting plate 18. The Maltese cross mechanism structure is connected to the second belt 23. The Maltese cross mechanism structure includes a driving wheel 24 rotatably mounted on the mounting plate 18 and connected to the second belt 23. The driving wheel 24 is adapted to a driven wheel 25 rotatably mounted on the mounting plate 18. The driven wheel 25 is coaxially connected to the transmission wheel 26.

[0072] When the rotating sleeve plate 16 and the telescopic plate 17 perform circular motion, it will drive the second bevel gear to rotate. The first bevel gear is fixed on the fixed sleeve 2. When the second bevel gear performs circular motion, the second bevel gear will rotate, and drive the driving wheel 24 through the transmission rod 21, the driven shaft 22 and the second belt 23. During the rotation of the driving wheel 24, the driving wheel 24 will cooperate with the driven wheel 25 and drive the driven wheel 25 to rotate periodically. When the driven wheel 25 rotates, it can drive one of the transmission wheels 26 to rotate, and make the transmission belt 27 sleeved on the transmission wheel 26 move. The transmission belt 27 drives the lifting member 29 to move upward through the fitting block 28 and the fitting groove 31. At this time, the scanning device 32 will also move upward. In this state, the rotating sleeve plate 16 rotates with the telescopic plate 17, so as to realize the omnidirectional scanning of the object.

[0073] It should be noted that when the rotating sleeve plate 16 and the telescopic plate 17 rotate one week, the driving wheel 24 rotates one week and drives the driven wheel 25 to rotate once, so that the scanning device 32 rises a certain height.

[0074] Through the above settings, during the circular motion of the scanning device 32, the scanning device 32 can move upward along the length direction of the mounting plate 18, so as to realize the omnidirectional scanning of the object, making the scanning result more accurate.

[0075] It should also be noted that the above transmission belt 27 can be regarded as composed of two straight line segments and two circular segments. When the fitting block 28 moves to the circular segment of the transmission belt 27, the fitting block 28 will slide in the fitting groove 31.

[0076] In summary, in the initial state, that is, when no object is placed, under the action of the spring 4, the abutting shaft 5 is in an upwardly jacked state. At this time, the protrusion 7 at the end of the equalizing member 6 connected to the abutting shaft 5 is at one end of the inclined groove 12, and at the same time, the plurality of abutting rods 10 are in a separated state. At the same time, in this state, the height of the abutting shaft 5 is the same as the height of the abutting rods 10. When an object is placed on the abutting shaft 5, under the action of the gravity of the object, the abutting shaft 5 is driven to move downward, compressing the spring 4 while causing the protrusion 7 to move downward with the equalizing member 6. At this time, the protrusion 7 is in sliding fit with the inclined groove 12, driving the guide plate 11 to move and driving the slider 9 to move along the length direction of the sliding groove 8, so that the plurality of abutting rods 10 move closer to each other to clamp the periphery of the object. And because the abutting shaft 5 is provided with ball bearings, when the object is not at the center of the receiving tray 3, under the action of the plurality of abutting rods 10, the object can be moved to the center position of the receiving tray 3, thus realizing positioning, so that in the subsequent scanning process, the obtained image information is more accurate.

[0077] When in use, by controlling the driving device 13 to work, the rotating sleeve 15 can be driven to rotate, and the rotating sleeve plate 16 connected to the rotating sleeve 15 can be made to perform a circular motion, so that the telescopic plate 17 performs a circular motion, thereby driving the scanning device 32 to perform a circular motion with the object as the center and collecting the external features of the object.

[0078] When the rotating sleeve plate 16 and the telescopic plate 17 perform a circular motion, the second bevel gear will be driven to rotate, and the first bevel gear is fixed on the fixed sleeve 2. When the second bevel gear performs a circular motion, the second bevel gear will rotate, and drive the driving wheel 24 through the transmission rod 21, the driven shaft 22 and the second belt 23. During the rotation of the driving wheel 24, the driving wheel 24 will cooperate with the driven wheel 25 and drive the driven wheel 25 to rotate periodically. When the driven wheel 25 rotates, one of the transmission wheels 26 can be driven to rotate, and the transmission belt 27 sleeved on the transmission wheel 26 can be made to move. The transmission belt 27 drives the lifting member 29 to move upward through the engaging block 28 and the engaging groove 31. At this time, the scanning device 32 will also move upward. In this state, the rotating sleeve plate 16 rotates with the telescopic plate 17, thus realizing the all-round scanning of the object.

[0079] It should be noted that when the rotating sleeve plate 16 and the telescopic plate 17 rotate one week, the driving wheel 24 rotates one week and drives the driven wheel 25 to rotate once, so that the scanning device 32 rises a certain height.
