Description

Technical Field

[0001] The utility model relates to the technical field of three-dimensional modeling, in particular to a multi-source data acquisition device for three-dimensional modeling. Background Art

[0002] A 3D model is a polygonal representation of an object, typically displayed on a computer or other video device. The displayed object can be either real-world or imaginary. Anything that exists in the physical world can be represented by a 3D model. 3D data acquisition involves collecting data from a three-dimensional object using a series of sensors or measuring devices. It is widely used in fields such as geographic surveying and filmmaking, and plays a vital role in the development of the national economy.

[0003] In order to perform three-dimensional modeling of an object, it is usually necessary to photograph the object to collect data. However, the shape, size and other parameters of the object vary, and different parts of the same object may also be different. This requires continuous adjustment of parameters such as the angle of the camera device and the distance between the camera device and the object to be modeled during the shooting process to obtain more comprehensive and accurate data.

[0004] Existing acquisition devices are often only designed for a certain shooting parameter. For example, some acquisition devices can rotate the camera device or the object with the middle of the object as the center to accurately adjust the shooting angle, but it is not convenient to adjust the distance between the object and the camera device. The focal length adjustment range is limited, and the shapes and sizes of different objects and different parts of the same object are different, so it is not convenient to use. In addition, if the camera device is rotated, the components that drive the camera device to rotate are often unevenly stressed; some acquisition devices can accurately adjust the distance between the object and the camera device, but it is not convenient to adjust the shooting angle, which makes it impossible to ensure the continuity of data acquisition during the shooting process; the object is usually placed on a stage, and the size of the object is usually fixed. If the size of the stage is too large, it may be difficult to adjust the distance between the object and the camera device. If the size of the stage is too small, the object may not be placed firmly.

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0050] See attached Figure 1 -Attached Figure 3 The embodiment of the utility model discloses a multi-source data acquisition device for three-dimensional modeling, including a frame 1, a rotating component 2, a bidirectional moving component 3, and a supporting component 4. The bottom of the frame 1 is provided with a vertical positioning column 5; the rotating component 2 is installed on the top of the frame 1 and is arranged corresponding to the positioning column 5; the middle part of the bidirectional moving component 3 is driven and connected to the bottom of the rotating component 2, and the bidirectional moving component 3 includes two relatively movable moving blocks 34, the bottom of one of the moving blocks 34 is connected to the multi-source shooting component 6, and the bottom of the other moving block 34 is connected to the counterweight component 7. The weight of 7 is substantially the same as that of the multi-source shooting assembly 6, so that the bidirectional moving assembly 3 is subjected to uniform force during the movement of the multi-source shooting assembly 6; the supporting assembly 4 is composed of a plurality of concentrically arranged annular structures 41, the outer diameter of one annular structure 41 being the same as the inner diameter of another adjacent annular structure 41 located outside the annular structure 41, and the inner diameter of the smallest annular structure 41 being the same as the outer diameter of the positioning column 5, so that the supporting assembly 4 can be fitted onto the outside of the positioning column 5 to form a columnar stage, and the diameter of the stage can be changed by adding or removing the annular structures 41.

[0051] In actual use, the number of annular structures 41 is adjusted according to the size of the object to be modeled, so that the size of the stage composed of the support assembly 4 and the positioning column 5 is slightly larger than the size of the object. This ensures that the stage 4 and the positioning column 5 can firmly support the object while minimizing the impact of the stage 4 on the distance between the object and the multi-source imaging assembly 6. After the object is placed, the two moving blocks 34 are driven by the bidirectional moving assembly 3 to move relative to each other, moving the multi-source imaging assembly 6 to an appropriate distance from the object. During the movement of the multi-source imaging assembly 6, the counterweight assembly 7, which has substantially the same weight as the multi-source imaging assembly 6, also moves accordingly, ensuring that the bidirectional moving assembly 3 is evenly stressed, less prone to misalignment, and more stable. The multi-source imaging assembly 6 is then activated to capture and collect data. After one side of the object is captured, the rotating assembly 2 on the frame 1 is activated, causing the multi-source imaging assembly 6 to rotate around the object, thereby capturing images of all sides of the object at a uniform speed, thereby obtaining more accurate, continuous, and uniform data. In summary, the use of this multi-source data acquisition device for 3D modeling facilitates the adjustment of the stage size and various parameters affecting modeling and imaging, and evenly stresses the bidirectional moving assembly when adjusting the spatial position of the multi-source imaging assembly.

[0052] See attached Figure 1 and attached Figure 6 There are many structures that can drive components to rotate, and one of them is introduced in this embodiment. Specifically, the rotating component 2 includes a first motor 21 and a rotating shaft 22. The first motor 21 is fixedly connected to the top of the frame 1; the rotating shaft 22 is vertically arranged, and the top of the rotating shaft 22 is drive-connected to the bottom of the first motor 21, and the bottom of the rotating shaft 22 is fixedly connected to the bidirectional moving component 3.

[0053] With the above structural design, when the first motor 21 is started, the rotating shaft 22 will rotate accordingly, thereby driving the bidirectional moving assembly 3, the multi-source shooting assembly 6 and the counterweight assembly 7 to rotate.

[0054] See attached Figure 2 and attached Figure 5 -Attached Figure 7There are many structures that can drive two components to move relative to each other. One of them is introduced in this embodiment. Specifically, a threaded hole 341 is provided in the middle of the moving block 34, and a slide groove 35 is provided at the top of the moving block 34. The bidirectional moving assembly 3 includes a first frame 31 that is basically in an inverted U shape, a second motor 32, and a bidirectional screw 33. The first frame 31 includes a horizontal side 311 at the top and vertical sides 312 at opposite ends of the horizontal side 311. The top of the horizontal side 311 is fixedly connected to the rotating shaft 22, and a long guide rail 36 is provided at the bottom of the horizontal side 311. The slide groove 35 is slidably connected to the guide rail 36; the second motor 32 is fixedly connected to one of the horizontal sides 311; the bidirectional screw 33 is rotatably connected between the two vertical sides 312, and one end of the bidirectional screw 33 is driven to connect to the second motor 32. The threaded hole 341 engages the screw, and the two moving blocks 34 are symmetrically arranged relative to the middle of the bidirectional screw 33.

[0055] With the above-described structural design, when the first motor 21 is activated, the rotating shaft 22 can drive the horizontal side 311 to rotate. When the second motor 32 is activated, the bidirectional screw 33 located between the two vertical sides 312 will rotate accordingly, causing the two moving blocks 34 to move toward each other along the extension direction of the guide rail 36. This in turn drives the multi-source imaging assembly 6 and the counterweight assembly 7 connected to the two moving blocks 34 to move relative to each other, thereby adjusting the distance between the multi-source imaging assembly 6 and the object. Furthermore, the counterweight assembly 7 ensures that the bidirectional moving assembly 3 maintains uniform force during the movement of the multi-source imaging assembly 6.

[0056] See attached Figure 2 and attached Figure 4 -Attached Figure 6 Furthermore, although under the action of the counterweight assembly 7, the bidirectional movable assembly 3 is subjected to uniform force, is not easily skewed or misplaced, and is more stable when moving or rotating, if the top of the bidirectional movable assembly 3 is only connected to the rotating shaft 22, it may cause the two sides of the horizontal side 311 to sag. In order to solve the above problem, two relatively arranged guide sliders 11 can be provided at the top of the horizontal side, and an annular guide groove 12 can be provided on the lower side of the top of the frame 1, wherein the guide slider 11 is a rotating body and the vertical cross-section is basically T-shaped, and the guide groove 12 is provided corresponding to the guide slider 11, so that the guide slider 11 and the guide groove 12 can cooperate to not only guide the rotation of the horizontal side 311, but also prevent the two sides of the horizontal side 311 from sagging.

[0057] See attached Figure 1 and attached Figure 8There are many types of annular structures, and one of them is introduced in this embodiment. Specifically, the annular structure 41 includes two supporting members 411 with a semi-annular cross-section, and each supporting member 411 is provided with a first magnetic member 412 at one end and a second magnetic member 413 at the other end. The corresponding two supporting members 411 can be magnetically connected through the cooperation of the first magnetic member 412 and the second magnetic member 413 to form a cylindrical annular structure 41.

[0058] Through the design of the above structure, there is no need to install the supporting assembly 4 from the top of the positioning column 5 with a certain height. The supporting assembly 4 can be disassembled and assembled from the side of the positioning column 5, which is more convenient and quick. During the installation process, the two corresponding supporting parts 411 are placed on the opposite sides of the positioning column 5, and then the two corresponding supporting parts 411 are gradually brought closer. After they are close to a certain extent, the two will actively connect under the magnetic action of the first magnetic part 412 and the second magnetic part 413. There is no need to lift the supporting assembly 4 upwards during the whole process. It has the advantages of simple structure, reliable connection, time saving and labor saving.

[0059] See attached Figure 8 Furthermore, since the outer surface of the annular structure 41 formed after the two corresponding supporting members 411 are connected is relatively smooth, it is not convenient to grip and exert force when disassembling. Therefore, an inward-concave hole 414 can be provided on the supporting member 411, which can not only serve as a gripping force point, but also reduce the weight of the supporting member 411, making the supporting member 411 easier to move; in order to further reduce the weight of the supporting member 411, the supporting member 411 can be made hollow inside, or made of light and strong materials.

[0060] See attached Figure 8 The process of shooting and collecting data is greatly affected by external light and darkness. In order to solve the above problem, the following design is carried out in this embodiment. Specifically, each annular structure 41 is embedded with multiple lamp beads 8, and the multiple lamp beads 8 on the same annular structure 41 are distributed in a circular array, which is used to fill in the light during the modeling shooting process and make the light distribution uniform.

[0061] Through the design of the above structure, after the object is placed on the loading platform composed of the supporting component 4 and the positioning column 5, the lamp beads 8 can be turned on for fill light, making the shooting scene brighter and the captured picture clearer; and because the multiple lamp beads 8 on the same annular structure 41 are distributed in a circular array, the light intensity on each side of the object is basically the same, and the brightness of the captured picture is basically the same, so that other factors other than the shape of the object itself have little effect on data collection, such as maintaining the same shooting angle, the same focal length, the same scene brightness, etc., so as to facilitate unified data collection; in addition, since the lamp beads 8 are embedded in the annular structure 41, they will not affect the placement of the object.

[0062] It should be noted that the above-mentioned lamp beads 8 adopt existing technology. In order to power them, a rechargeable battery can be built into the annular structure 41, and a charging socket can be set on the outer surface of the annular structure 41 to facilitate charging; replaceable dry batteries can also be used for power supply. In this case, sufficient space needs to be reserved for replacement operations, such as hollowing out the bottom of the annular structure 41 and setting a battery compartment with a cover in the above-mentioned hollowed-out part; the above methods are all existing technologies and will not be described in detail here.

[0063] See attached Figure 2 and attached Figure 9 -Attached Figure 11 In the actual process of shooting and collecting data, according to the influence of factors such as the size and shape of the object, multiple parameters affecting the shooting also need to be adjusted accordingly. In order to be able to adjust more parameters more conveniently, the following design is carried out in this embodiment. Specifically, the multi-source shooting component 6 includes a second frame 61 and multiple plates 62. The second frame 61 is basically square ring-shaped. The top of the second frame 61 is connected to the moving block 34. Long first through holes 63 are provided on the two vertical surfaces. The first through holes 63 are provided with multiple positioning grooves 64 linearly arranged in the vertical direction. The length of the positioning grooves 64 is greater than the width of the first through holes 63; each plate 62 is connected to a camera device 9 with damping rotation for collecting data of the object and adjusting the shooting angle of the camera device 9 on the vertical plane. Both ends of the plate 62 A slider 65 is provided which corresponds to the two first through holes 63 respectively. The slider 65 is slidably connected to the first through holes 63 so that the plate body 62 and the slider 65 can move up and down along the extension direction of the first through holes 63. A rotatable spring telescopic rod 66 is provided on the slider 65. The end of the spring telescopic rod 66 away from the plate body 62 is connected to a positioning block 67. The positioning block 67 is arranged corresponding to the positioning groove 64. The spring telescopic rod 66 can be extended, and in a natural state, the positioning block 67 is pressed tightly in the positioning groove 64. By moving the positioning block 67 to different positioning grooves 64, the height of the plate body 62 and the camera device 9 can be changed. The width of the positioning block 67 is less than or equal to the width of the first through hole 63, so that the positioning block 67 can correspond to the first through hole 63 by rotation, so that the plate body 62 can be removed from the second frame 61 by tilting.

[0064] When the cam 62 is in the vertical direction of the second through hole 63, the positioning blocks 67 are automatically reset and enter the positioning grooves 64 of the corresponding heights under the elastic force of the spring telescopic rod 66, thereby completing the height adjustment of the plate 62 and the camera device 9. When the camera device 9 needs to be removed, the positioning blocks 67 can be pulled out of the corresponding positioning grooves 64 and then rotated around the spring telescopic rod 66 as the axis until the extension direction of the positioning blocks 67 is consistent with the extension direction of the first through hole 63. At this time, the plate 62 is tilted in the plane passing through the two first through holes 63, and the positioning blocks 67 can pass through the first through hole 63, so that the various components directly connected to the plate 62 and the camera device 9 can be removed from the second frame 61.

[0065] Based on the above scheme, the multi-source data acquisition device for three-dimensional modeling can adjust the shooting angle of the camera device 9 in the horizontal direction through the rotating component 2, can adjust the distance between the camera device 9 and the object to be modeled through the bidirectional moving component 3, can adjust the shooting height of the camera device 9 through the cooperation of components such as the plate 62, and can adjust the shooting angle of the camera device 9 in the vertical direction through a damped rotating connection; in general, through the design of the above structure, the data of the object to be modeled can be collected more conveniently, quickly and accurately.

[0066] See attached Figure 2 and attached Figure 12 -Attached Figure 14 There are many structures that can play the role of counterweight, and one of them is introduced in this embodiment. Specifically, the counterweight assembly 7 includes a third frame 71 and a plurality of counterweight blocks 72. The third frame 71 is basically a square ring, and the bottom of the third frame 71 is provided with a plurality of first positioning holes 73; the bottom of each counterweight block 72 is provided with a plurality of positioning rods 74, and the plurality of positioning rods 74 correspond one-to-one to the plurality of first positioning holes 73; each counterweight block 72 is provided with a plurality of second positioning holes 75, and the plurality of second positioning holes 75 correspond one-to-one to the plurality of positioning rods 74.

[0067] Through the design of the above structure, the multiple positioning rods 74 on a counterweight block 72 can be respectively inserted into the multiple first positioning holes 73, thereby preventing the counterweight block 72 and the third frame 71 from being misplaced in the horizontal direction. The above operation is to place the first counterweight block 72 on the third frame 71; the multiple positioning rods 74 on a counterweight block 72 can also be respectively inserted into the multiple second positioning holes 75 on another counterweight block 72, so that different counterweight blocks 72 can be stacked on each other and prevented from being misplaced in the horizontal direction. This operation is to stack multiple counterweight blocks 72.

[0068] See attached Figure 13 Furthermore, the following design is also carried out in this embodiment. Specifically, a concave handle 721 is provided on the top of the counterweight block 72 to facilitate taking and placing.
