[0001] This utility model belongs to the field of three-dimensional scanning technology, and in particular relates to a scanning device and a three-dimensional scanning system. Background Technology

[0002] Currently, existing handheld scanners are bulky and inconvenient to carry. Furthermore, handheld scanners require constant monitoring of the workstation display (such as a computer or monitor) during scanning, which makes them inconvenient to operate. Utility Model Content

[0003] In view of this, it is necessary to provide a scanning device and a 3D scanning system for solving the above-mentioned technical problems.

[0004] A scanning device, the scanning device comprising:

[0005] case;

[0006] The electrical module is installed inside the housing;

[0007] The laser module is installed inside the housing and is electrically connected to the electrical module;

[0008] An image acquisition component is installed inside the housing and electrically connected to the electrical module. The image acquisition component includes multiple camera modules, which are arranged sequentially with the laser module along the length of the housing.

[0009] The touch screen is mounted on the housing and is electrically connected to the electrical module.

[0010] It is understandable that arranging the laser module and multiple camera modules along the length of the housing makes the overall structure of the scanning device compact. This reduces the overall size of the scanning device, making it easier for users to carry and operate. Furthermore, users can directly observe and operate the scanning device through the touch screen, which further improves the convenience of user operation.

[0011] In one embodiment, the number of camera modules is configured to be three, and the three camera modules are respectively defined as a first monochrome camera, a color camera, and a second monochrome camera;

[0012] The first monochrome camera and the color camera are arranged on one side of the laser module, and the second monochrome camera is arranged on the other side of the laser module.

[0013] It is understandable that by utilizing the structural characteristics of black-and-white and color cameras, this scanning device can ultimately obtain graphic data with or without color, depending on the user's needs.

[0014] In one embodiment, the laser module includes an infrared laser, a blue laser, and a vertical-cavity surface-emitting laser.

[0015] It is understandable that by utilizing the structural characteristics of infrared lasers, blue lasers, and vertical cavity surface-emitting lasers, the application scenarios of this scanning device can be expanded to meet users' needs for scanning different targets in different scenarios.

[0016] In one embodiment, the laser module includes an infrared laser and a blue laser;

[0017] The infrared laser and / or the blue laser are detachably mounted within the housing.

[0018] It is understandable that the above-described structural design allows the infrared laser and / or blue laser to be customized according to user needs to meet the different scanning requirements of the scanning device.

[0019] In one embodiment, the scanning device further includes a transparent plate disposed on the light output path of the laser module and connected and sealed to the housing.

[0020] Understandably, the above structural design enables the transparent plate to prevent dust from being used to mount the laser module on the housing, and also enhances the overall quality of the scanning device.

[0021] In one embodiment, the touchscreen is disposed on the back of the housing;

[0022] The touch screen has a preset angle between its display plane and the length of the housing.

[0023] Understandably, the above-mentioned structural design facilitates interaction between the user and the touchscreen.

[0024] In one embodiment, the touch screen includes a display module and a control module, wherein the display module is electrically connected to the electrical module and is used to display the working status of the scanning device;

[0025] The control module is electrically connected to the electrical module and is used to interact with the user to control the scanning device.

[0026] In one embodiment, the scanning device further includes a pre-processing module, which is installed inside the housing and electrically connected to the electrical module.

[0027] It is understandable that the above-mentioned structural setup enables the scanning device to preprocess the scanned data using a pre-processing module. This reduces the computational burden on the backend when processing the data transmitted by the scanning device, thus reducing the equipment configuration required for the data processing equipment associated with the scanning device.

[0028] In one embodiment, the scanning device further includes a heat dissipation component that is thermally connected to the electrical module and is capable of actively dissipating heat from the electrical module.

[0029] It is understandable that using heat dissipation components to actively cool the electrical module can quickly dissipate heat from the electrical module and prevent the electrical module from affecting its working performance due to heat accumulation.

[0030] In one embodiment, the heat dissipation component includes a fan;

[0031] The housing has an air inlet and an air outlet, the air inlet and the air outlet are connected to form a ventilation duct, and the ventilation duct is used to house the fan.

[0032] It is understandable that air cooling is used to dissipate heat from the electrical modules, thus achieving rapid heat dissipation.

[0033] In addition, this application also provides a three-dimensional scanning system, including the scanning device described above.

[0034] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0035] The scanning device and 3D scanning system claimed in this application arrange the laser module and multiple camera modules along the length of the housing, making the overall structure of the scanning device compact. This reduces the overall size of the scanning device, making it easier for users to carry and operate. Furthermore, users can directly observe and operate the scanning device through a touch screen, which further improves the convenience of user operation. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] The scanning device 100 that this application seeks to protect specifically refers to a handheld scanner.

[0044] like Figures 1 to 5 As shown, the scanning device 100 provided in this application includes a housing 10, an electrical module (not shown), a laser module 20, an image acquisition component 30, and a touch screen 40. The electrical module, laser module 20, and image acquisition component 30 are all installed inside the housing 10. The laser module 20 and image acquisition component 30 are electrically connected to the electrical module. The image acquisition component 30 includes multiple camera modules, which are arranged sequentially with the laser module 20 along the length of the housing 10. The touch screen 40 is installed on the housing 10 and is electrically connected to the electrical module.

[0045] As can be seen from the above, by arranging the laser module 20 and multiple camera modules along the length of the housing 10, the overall structure of the scanning device 100 is made compact. This reduces the overall size of the scanning device 100, making it easier for users to carry and operate. Furthermore, users can directly observe and operate the scanning device 100 through the touch screen 40, which further improves the convenience of operating the scanning device 100.

[0046] like Figure 5 As shown, the laser module 20 includes an infrared laser 21, a blue laser 22, and a vertical-cavity surface-emitting laser 23. This allows the scanning device 100 to utilize the structural characteristics of the infrared laser 21, blue laser 22, and vertical-cavity surface-emitting laser 23, expanding its application scenarios to meet user needs for scanning different targets in various situations. Here, there are two infrared lasers 21, two blue lasers 22, and two vertical-cavity surface-emitting lasers 23, with the infrared laser 21 and blue laser 22 positioned at the midpoint of the length of the housing 10.

[0047] It should be noted that the infrared laser 21, blue laser 22, and vertical-cavity surface-emitting laser 23 mentioned above are positioned on the scanning device 100 to meet the requirement of the largest laser-filled area within the common field of view. Among them, the vertical-cavity surface-emitting laser 23 and the infrared laser 21 are mainly used for large-area scanning. The difference is that the infrared laser 21 requires the affixing of marker points, but its accuracy and scanning effect are slightly better. The blue laser 22 is mainly used for detailed scanning and also requires the affixing of marker points.

[0048] like Figure 5As shown, in one embodiment, the infrared laser 21 and / or the blue laser 22 are detachably installed within the housing 10. Preferably, both the infrared laser 21 and the blue laser 22 can be individually detached. This allows the infrared laser 21 and / or the blue laser 22 to be customized according to user needs to meet different scanning requirements of the scanning device 100. Specifically, the infrared laser 21 and the blue laser 22 can be assembled into the housing 10 via a quick-release structure, achieving rapid replacement and making it more convenient to use.

[0049] like Figure 1 As shown, the scanning device 100 also includes a transparent plate 11, which is disposed on the light output path of the laser module 20 and is connected and sealed to the housing 10. This allows the transparent plate 11 to provide dust protection for the laser module 20 assembled on the housing 10 and enhances the overall quality of the scanning device 100. Specifically, the transparent plate 11 can be a glass panel, and a sealing ring or sealant can be used to achieve the assembly seal between the transparent plate 11 and the housing 10. It is understood that in other embodiments, the transparent plate 11 can also be an acrylic plate, which will not be elaborated upon here.

[0050] like Figure 5 As shown, the camera module configuration consists of three modules: a first monochrome camera 31, a color camera 32, and a second monochrome camera 33. The first monochrome camera 31 and the color camera 32 are positioned on one side of the laser module 20, while the second monochrome camera 33 is positioned on the other side. This utilizes the structural characteristics of the monochrome and color cameras, allowing the scanning device 100 to obtain graphic data with or without color as needed, thus meeting user requirements. Here, the second monochrome camera 33 is arranged together with the vertical-cavity surface-emitting laser 23 and covered by a transparent plate 11, while the first monochrome camera 31 and the color camera 32 are also covered by a transparent plate 11.

[0051] like Figure 2 , Figure 4 As shown, the touchscreen 40 is located on the back of the housing 10; wherein, the plane direction of the display surface 41 on the touchscreen 40 forms a preset angle with the length direction of the housing 10. That is, the display surface 41 on the touchscreen 40 is tilted, so that when the user operates the scanning device 100, the display surface 41 of the touchscreen 40 is directly facing the user, which facilitates interaction between the user and the touchscreen 40. Here, the touchscreen 40 can support the selection of scanning mode, and zoom in and out of the scanning area. In addition, the touchscreen 40 can also display the connection status of the scanning device 100 and the device temperature, etc.

[0052] In one embodiment, the scanning device 100 further includes a pre-computation module (not shown in the figure), which is installed in the housing 10 and electrically connected to the electrical module. This enables the scanning device 100 to preprocess the scanned data using the pre-computation module, thereby reducing the computational power required for the backend to process the data transmitted by the scanning device 100. In this way, it can reduce the device configuration of the data processing device that is配套 with the scanning device 100. It should be noted that the specific structure of the pre-computation module and the working principle of how to preprocess the scanned data during operation can adopt existing conventional methods, and will not be elaborated here.

[0053] It can be understood that since the scanning device 100 is integrated with a pre-computation module capable of preprocessing data, this results in a large amount of computational processing by the electrical module when the scanning device 100 is operating, and a large amount of heat will also be generated. For this reason, the scanning device 100 of this embodiment further includes a heat dissipation component (not shown in the figure), which is thermally connected to the electrical module, and the heat dissipation component can actively dissipate heat from the electrical module, so as to quickly dissipate the heat on the electrical module and prevent the electrical module from being affected by heat accumulation and affecting its working performance.

[0054] As Figures 1 to 5 shown, the heat dissipation component includes a fan (not shown in the figure); the housing 10 is provided with an air inlet 101 and an air outlet 102, the air inlet 101 and the air outlet 102 are connected and form a ventilation duct (not shown in the figure), and the ventilation duct is used to accommodate the fan. Here, the air inlet 101 and the air outlet 102 are provided at two ends of the housing 10 in the length direction. That is to say, when the heat dissipation component is working, it can dissipate heat from the electrical module in an air-cooling manner, so as to achieve rapid heat dissipation of the electrical module. It should be noted that the number and shape of the air inlet 101 and the air outlet 12 on the housing 10 can be specifically set according to the usage requirements, and will not be elaborated here. It can be understood that the scanning device 100 is not limited to dissipating heat from the electrical module in an air-cooling manner. For those skilled in the art, a TEC cooling chip can also be used to dissipate heat from the electrical module.

[0055] In addition, the present application also provides a three-dimensional scanning system, including the scanning device 100 described above.

[0056] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0057] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the present utility model shall fall within the scope of protection claimed by the present utility model.
