Description

Background Art

[0002] During the 3D scanning of vehicle-mounted screen products, due to the field of view of the 3D camera, it is often impossible to scan the workpiece once to obtain the corresponding standard model.

However, most of the current calibration models on the market are dedicated models, that is, it is necessary to manufacture multiple models with specific shapes and structures to meet the scanning of different regions of the workpiece, and then complete the creation of the overall model through the splicing of multiple graphics. In the method of making dedicated models, it takes a certain amount of time from the production, assembly, and application of the dedicated model, and it is difficult to find common points in the splicing time of multiple individual scanned images, resulting in the problem of difficult image splicing.

[0037] Next, the embodiments of the present application will be described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time.

[0039] An embodiment of the present application provides an intelligent 3D image mosaic and calibration device for a vehicle glass screen, including two spliced calibration pieces;

[0040] Any one of the calibration pieces includes a first calibration part, a second calibration part, and a third calibration part connected in sequence. The first calibration part is perpendicular to the third calibration part, and the second calibration part has at least three uniformly distributed inclined surfaces;

[0041] The 3D camera scans the first calibration part and generates a first standard model. The 3D camera rotates 90° relative to the intelligent 3D image mosaic and calibration device for the vehicle glass screen to scan the third calibration part and generate a second standard model. Among them, both the first standard model and the second standard model include at least one of the same inclined surfaces.

[0042] The present application also provides an intelligent 3D image mosaic and calibration method for a vehicle glass screen, which is applied to the intelligent 3D image mosaic and calibration device for the vehicle glass screen described above, and includes the following steps:

[0043] Fix the intelligent 3D image mosaic and calibration device for the vehicle glass screen on the workpiece;

[0044] Scan the first calibration part on the intelligent three-dimensional image stitching and calibration device for vehicle-mounted glass screens to generate a first standard model;

[0046] Stitch the first standard model and the second standard model into a workpiece model based on the same parts on the first standard model and the second standard model.

[0047] The above-provided intelligent three-dimensional image stitching and calibration device and method for vehicle-mounted glass screens sequentially set a first calibration part, a second calibration part, and a third calibration part, and evenly distribute at least three inclined planes on the second calibration part. After the 3D camera scans the first calibration part and generates the first standard model, by flipping 90° and then scanning the third calibration part to generate the second standard model, there are inclined plane parts on the second standard model that are the same as those on the first standard model. Thus, the first standard model and the second standard model are stitched through the same inclined plane, better realizing the stitching of the workpiece model, avoiding the problem of stitching misalignment caused by the lack of the same parts or the small size of the same parts in the generated multiple models, and improving the stitching accuracy and efficiency.

[0048] Next, in conjunction with the accompanying drawings, some embodiments of the present application will be described in detail. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0049] Embodiment 1

[0050] Please refer to Figure 1 and Figure 2 Embodiment 1 of the present application provides an intelligent three-dimensional image stitching and calibration device 100 for vehicle-mounted glass screens, including two spliced calibration parts 10. Further, the two calibration parts 10 are used to clamp the workpiece 200 between the two calibration parts 10, so as to directly install the workpiece 200 on the two calibration parts 10, thus avoiding the cumbersome operation of using corresponding jigs and other auxiliary installation tools that must be used for a customized model, and improving work efficiency. Preferably, in order to ensure the firm fixation of the workpiece 200, the number of intelligent three-dimensional image stitching and calibration devices 100 for vehicle-mounted glass screens is four, which are respectively fixed at the four corners of the workpiece 200.

[0051] Specifically, the above workpiece 200 is a sheet-like structure. Preferably, the workpiece 200 is glass.

[0052] Further, an installation opening 10a for installing the workpiece 200 is provided between the two calibration parts 10, so as to complete the installation of the workpiece 200 by inserting the workpiece 200 into the installation opening 10a during the scanning and installation process of the workpiece 200.

[0053] In one embodiment, two calibration members 10 are integrally formed, and an opening, i.e., the structure of the mounting opening 10a, is formed between the two integrally formed calibration members 10. It can be understood that the arrangement of the two calibration members 10 is not limited to this. For example, in another embodiment, the two calibration members 10 are detachably connected. Preferably, the two calibration members 10 are fixed by screws.

[0054] It can be understood that by fixedly installing the workpiece 200 in the mounting opening 10a, when the workpiece 200 is in a sheet-like structure, the workpiece 200 can be inserted into the mounting opening 10a to complete the installation of the workpiece 200. It has strong applicability, avoids the problem of needing to re-customize the model due to the differences in the shape and size of the workpiece 200, reduces costs, saves the time for customizing the model, and improves work efficiency.

[0055] In one embodiment, the calibration member 10 is generally a flat plate structure. And the calibration member 10 is made of light materials, such as fiberboard, aluminum alloy, etc., so as to avoid the problem that the workpiece 200 is extruded and deformed due to the weight of the calibration block during use.

[0056] Furthermore, any one of the calibration members 10 includes a first calibration portion 11, a second calibration portion 12, and a third calibration portion 13 that are connected in sequence. Specifically, the first calibration portion 11 is perpendicular to the third calibration portion 13. More specifically, the first calibration portion 11 and the third calibration portion 13 are straight rod structures, and the two straight rods are perpendicular to each other.

[0057] In a specific embodiment, the second calibration portion 12 is an arc-shaped plate structure, and the two ends are respectively connected to the first calibration portion 11 and the third calibration portion 13.

[0058] Still further, the second calibration portion 12 has at least three inclined surfaces 12a that are evenly distributed. Preferably, the number of the inclined surfaces 12a is three. When the 3D camera scans and irradiates along a direction, at least two inclined surfaces 12a on the second calibration portion 12 can be scanned, so as to generate a first standard model having at least two inclined surfaces 12a. And when the 3D camera flips 90° relative to the vehicle-mounted glass screen intelligent three-dimensional image stitching and calibration device 100 to scan and irradiate the third calibration portion 13, the 3D camera can still irradiate at least two of the inclined surfaces 12a, so as to generate a second standard model having at least the inclined surfaces 12a. Since there are three inclined surfaces 12a, there is a same inclined surface 12a in the first standard model and the second standard model after flipping and scanning and irradiating. Therefore, when the first standard model and the second standard model are stitched, the first standard model and the second standard model can be positioned through the same inclined surface 12a, so as to prevent the problem of displacement deviation of the generated workpiece 200 model and improve the stitching accuracy and efficiency.

[0059] It can be understood that the number of the inclined surfaces 12a is not limited to this. For example, in another embodiment, the number of the inclined surfaces 12a may also be four, five, six, etc.

[0060] Specifically, please refer to Figure 2 , when the 3D camera exists in any direction of the in-vehicle glass screen intelligent three-dimensional image splicing and calibration device 100, since the inclined surfaces 12a at both ends are respectively connected to the upper and lower end faces of the first calibration part 11 and the second calibration part 12, and due to the deflection angle, the length of the inclined surface 12a located below extending in the vertical direction is greater than the length of any one of the inclined surfaces 12a extending in the vertical direction. Even when the scanning direction of the 3D camera is parallel to the extending direction of the first calibration part 11 and the third calibration part 13, that is, when the 3D camera is located at the lowest and the highest positions, the 3D camera can still scan more than half of the inclined surfaces 12a. Thus, when the 3D camera forms corresponding standard models through two scans, there will inevitably be overlapping parts between the two standard models, and the standard models are spliced through the overlapping parts, thereby ensuring the splicing accuracy of the workpiece 200.

[0061] Furthermore, the included angle between the central axes of every two adjacent inclined surfaces 12a is 0° - 30°. It should be noted that when the number of the inclined surfaces 12a is three, the included angle between the central axes of every two adjacent inclined surfaces 12a is 30°. However, as the number of the inclined surfaces 12a increases, the included angle between every two adjacent inclined surfaces 12a will decrease accordingly. The specific angle depends on the specific number of the inclined surfaces 12a set.

[0062] Still further, the in-vehicle glass screen intelligent three-dimensional image splicing and calibration device 100 further includes a plurality of first positioning members 20. Each positioning member is respectively arranged on each inclined surface 12a to form feature points, which is convenient for the 3D camera to capture, thereby avoiding the problem that the 3D camera cannot capture due to the relatively flat inclined surface 12a. Preferably, the first positioning member 20 is a cylinder.

[0063] In order to better scan and capture the first calibration part 11 and the third calibration part 13, the in-vehicle glass screen intelligent three-dimensional image splicing and calibration device 100 further includes a plurality of second positioning members 30 and third positioning members 40 for the 3D camera to scan. A plurality of second positioning members 30 are arranged on the first calibration block, and a plurality of third positioning members 40 are arranged on the second calibration block, so that when the 3D camera scans the above-mentioned plurality of second positioning members 30 and plurality of third positioning members 40, the shape and position of the first calibration part 11 and the third calibration part 13 can be accurately obtained.

[0064] Further, the first calibration portion 11 has a first scanning surface 11a, and the third calibration portion 13 has a second scanning surface 13a. Preferably, the first scanning surface 11a and the third scanning surface 11b face away from the workpiece 200, and the first scanning surface 11a, the plurality of inclined surfaces 12a, and the second scanning surface 13a are connected in sequence. A plurality of second positioning members 30 are provided on the first scanning surface 11a, and a plurality of third positioning members 40 are provided on the second scanning member, so that when the 3D camera scans the plurality of second positioning members 30 and the plurality of third positioning members 40, the portion of the side wall of the workpiece 200 can be scanned.

[0065] Still further, the first calibration portion 11 further has a third scanning surface 11b perpendicular to the first scanning surface 11a, and the second calibration portion 12 further has a fourth scanning surface 13b perpendicular to the second scanning surface 13a. That is, the third scanning surface 11b and the fourth scanning surface 13b are the inner side surfaces of the in-vehicle glass screen intelligent three-dimensional image splicing and calibration device 100. Further, in order to better scan the inner side surface of the workpiece 200, the in-vehicle glass screen intelligent three-dimensional image splicing and calibration device 100 further includes a plurality of fourth positioning members 50 provided on the third scanning surface 11b and a plurality of fifth positioning members 60 provided on the fourth scanning surface 13b, so that when the workpiece 200 and the in-vehicle glass screen intelligent three-dimensional image splicing and calibration device 100 are turned laterally, the 3D camera can scan the plurality of third positioning members 40 and the plurality of fourth positioning members 50, thereby accurately obtaining the specific shape and size of the side surface of the workpiece 200.

[0066] Preferably, the second positioning member 30, the third positioning member 40, the fourth positioning member 50, and the fifth positioning member 60 are cylinders.

[0067] To prevent the problem that the workpiece 200 detaches or slides out of the mounting opening 10a due to shaking or impact, the in-vehicle glass screen intelligent three-dimensional image splicing and calibration device 100 further includes a plurality of first fasteners (not shown in the figure). Specifically, fastening holes 10b are formed on the third scanning surface 11b and the fourth scanning surface 13b of each calibration member 10, and each first fastener is movably disposed in each fastening hole 10b. When it is necessary to clamp the workpiece 200 in the mounting opening 10a, the first fastener is moved inward, and the end of the first fastener abuts against the workpiece 200 to realize clamping of the workpiece 200, and the workpiece 200 is loosened by moving outward, thereby facilitating replacement of the workpiece 200. Preferably, the first fastener is a machine screw.

[0068] To ensure the fastening of the two calibration parts 10 and prevent the loosening of the two calibration parts 10 caused by shaking or impact, the intelligent three-dimensional image splicing and calibration device 100 for vehicle-mounted glass screens further includes a plurality of second fasteners (not shown in the figure). Specifically, the intelligent three-dimensional image splicing and calibration device 100 for vehicle-mounted glass screens further includes a first fixing part 14 provided at the end of the first calibration part 11 and a second fixing part 15 provided at the end of the third calibration part 13. Among them, the first fixing part 14 is provided with a first fixing hole 14a, and the second fixing part 15 is provided with a second fixing hole 15a. A plurality of second fasteners can be fixed in each first fixing hole 14a and each second fixing hole 15a to fix the two calibration parts 10. Preferably, the second fastener is a screw.

[0069] To facilitate the collection of the first standard model and the second standard model and compare them. The intelligent three-dimensional image splicing and calibration device 100 for vehicle-mounted glass screens further includes an execution device (not shown in the figure) and a signal collection device (not shown in the figure), so as to perform coordinate conversion between the actual product and the splicing model through the signal collection device and the execution device, so as to replace the actual coordinate position of the product with the virtual coordinate position in the execution device for image splicing. Specifically, the existing six-axis comparison system is used for coordinate conversion, which will not be elaborated here.

[0070] The above-mentioned intelligent three-dimensional image splicing and calibration device 100 for vehicle-mounted glass screens sequentially sets the first calibration part 11, the second calibration part 12, and the third calibration part 13, and evenly distributes at least three inclined surfaces 12a on the second calibration part 12. After the 3D camera scans the first calibration part 11 and generates the first standard model, by flipping 90° and then scanning the third calibration part 13, the generated second standard model has the same inclined surface 12a part as the first standard model. Therefore, the first standard model and the second standard model are spliced through the same inclined surface 12a, so as to better realize the splicing of the workpiece 200 model, avoid the problem of splicing misalignment caused by the lack of the same part or the small same part in the generated multiple models, and improve the splicing accuracy and efficiency.

[0076] S40: Stitch the first standard model and the second standard model into the workpiece 200 model according to the same parts on the first standard model and the second standard model.

[0077] It should be noted that the calibration method described in the second embodiment is applied to the intelligent three-dimensional image stitching and calibration device 100 in the first embodiment. Therefore, the steps in the second embodiment are the same as those in the first embodiment and can produce the same beneficial effects as those in the first embodiment, which will not be elaborated here.

[0078] The above are only the implementation manners of the present application. It should be pointed out here that for those of ordinary skill in the art, improvements can be made without departing from the creative concept of the present application, but these all belong to the protection scope of the present application.
