[0019] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0021] Currently, tracking scanners consist of a tracker, a scanner, and a sphere frame. The scanner is integrated into the sphere frame to perform 3D scanning of objects. During the movement of the scanner, the tracker can track the movement of the scanner through coded patterns (such as marker points, coded points, etc.) on the sphere frame, thereby registering the point cloud of the object captured by the scanner to the same coordinate system, realizing pointless scanning of objects and scanning of large objects.

[0022] Among them, the ball frame that integrates a scanner can perform independent scanning without the tracker, but it is usually heavy, lacks flexibility, and is difficult to adapt to small spaces.

[0023] Based on this, this application provides an optical device in which the optical components are detachably connected to the main frame and the handle is detachably connected to the main body. The optical components and the handle components are not directly connected. In this way, the optical components can be used independently to achieve handheld portability, or they can be used in conjunction with the main frame and the handle. This allows the form of the optical device to meet the needs of different measurement scenarios and improve the user's operating freedom and experience.

[0024] like Figures 1 to 3 As shown, this application provides an optical device, including a main frame 1, an optical component 2, and a handle 3.

[0025] The aforementioned main frame 1 includes multiple targets 12 and a main support structure 11. The multiple targets 12 are located at multiple fixed joints 112 of the main support structure 11, and each target 12 includes multiple marker points. The main support structure 11 also includes a first mounting space 5 and a second mounting space 6 located on opposite sides of the main support structure 11.

[0026] The aforementioned optical component 2 is detachably connected to the first mounting space 5, and the optical component 2 is used to perform three-dimensional scanning of the object.

[0027] The aforementioned handle 3 is detachably connected to the second mounting space 6. The optical component 2 and the handle 3 are not directly connected.

[0028] Understandably, since the optical component 2 is detachably connected to the first mounting space 5 and the handle 3 is detachably connected to the second mounting space 6, and the optical component 2 and the handle 3 are not directly connected, the optical component 2 can be used independently for scanning in confined spaces, offering flexible operation. It can also be used in larger spaces integrated with the main frame 1 and the handle 3, enabling the tracker to track the motion of the optical device based on the target 12 without needing to attach markers or coded patterns to the scanned object. This allows the optical component 2 in the optical device to better scan medium to large-sized workpieces. This design allows the optical device to adapt to different scenario requirements, providing users with greater operational freedom and a better experience.

[0029] For example, refer to Figure 3 and Figure 4 The aforementioned optical component 2 can be selected as a scanning device, which includes an imaging module. The imaging module is used to project structured light onto an object (e.g., a workpiece, a biological object (partial or complete), equipment, etc.) and capture at least a portion of the reflected structured light. Figure 4 A schematic diagram of an exemplary scanning device is shown.

[0030] In the depicted embodiments, the scanning device includes a frame structure 22 and an imaging module 21 located within the frame structure 22. The imaging modules 21 may be arranged side-by-side such that the fields of view of each imaging module at least partially overlap. In some embodiments, the imaging module 21 may include three cameras: a first camera 211, a second camera 212, and a third camera 214. The imaging module 21 may also include a light projector 213, which may include a light source, a collimating lens, and diffractive optical elements. The light source is configured to emit a light beam toward the lens, and the collimated light beam propagates to the diffractive optical elements. The diffractive optical elements replicate the focused light beam to form a speckle pattern or fringe pattern and project it onto the scanned object / area. The speckle image or fringe pattern is reflected back from the scanned object / area and acquired by the imaging module 21 for further processing by a processing chip (not shown) to obtain three-dimensional information of the scanned object / area. In other embodiments, the light projector 213 may be an image projector, such as a digital micromirror device, a liquid crystal display projector, or an organic electroluminescent display projector.

[0031] In some embodiments, the light projector 213 may include a single light source, such as a light source emitting infrared light, white light, blue light, or other visible monochromatic light. In other embodiments, the light projector 213 is configured to emit light with wavelengths between 405 nm and 1100 nm. In still other embodiments, the light projector 213 may include two or three identical light sources, such as two or three light sources emitting infrared light. Alternatively, the light projector 213 may include two or three different light sources, such as a first light source emitting infrared light and a second light source emitting white light, or a first light source emitting infrared light, a second light source emitting white light, and a third light source emitting blue light. The two or three identical light sources may be part of the same light projector 213 or may be implemented as separate units (e.g., in an additional light projector unit), and similarly, the two or three different light sources may be part of the same light projector 213 or may be implemented as separate units (e.g., in an additional light projector unit).

[0032] In some embodiments, the imaging module 21 may also include another light projector (not shown), such as a speckle pattern projector, a stripe pattern projector, or an image projector.

[0033] The first camera 211 and the third camera 214 are typically monochrome (e.g., black and white) cameras, and their types will depend on the type of light source(s) used in the light projector 213. In some embodiments, the first camera 211 and the third camera 214 may be monochrome, visible spectrum, or near-infrared cameras, and the light projector 213 may be an infrared or near-infrared light projector. The first camera 211 and the third camera 214 may use any suitable shutter technology, including but not limited to rolling shutters, global shutters, mechanical shutters, and optical liquid crystal display (LCD) shutters.

[0034] In some embodiments, the second camera 212 may be a color camera (also known as a texture camera). The texture camera may use any suitable shutter technology, including but not limited to rolling shutters, global shutters, mechanical shutters, and optical liquid crystal display (LCD) shutters.

[0035] In some embodiments, the first camera 211, the second camera 212, and the third camera 214 may have similar configurations to improve matching confidence and speed. In other embodiments, the imaging module 21 may further include the third camera 214, such that the scanning device includes three monochrome cameras and one color camera. In further embodiments, the imaging module may also be able to use a single camera to acquire reflected light and color texture, omitting the other cameras.

[0036] like Figure 4 As shown, a first camera 211, a second camera 212, a light projector 213, and a third camera 214 can be located side-by-side on one surface of the frame structure 22, spaced apart from each other, and all facing directly forward of the surface. In some examples, the first camera 211 has a first field of view facing the front region of the surface, the second camera 212 has a second field of view facing the front region of the surface, the third camera 214 has a third field of view facing the front region of the surface, and the light projector 213 has a projected field of view facing the front region of the surface. In some examples, the first field of view and the projected field of view at least partially overlap, the second field of view and the projected field of view at least partially overlap, the third field of view and the projected field of view at least partially overlap, and the first field of view, the second field of view and the third field of view at least partially overlap.

[0037] A data connection (such as USB or serial communication connection) between the scanning device and one or more computer processors (not shown) allows the transmission of data collected by the first camera 211, the second camera 212, and the third camera 214, enabling it to be processed to derive 3D measurements of the surface of the scanned object / object. The one or more computer processors may be implemented in a remote computing system (electronic device), or alternatively, may be part of the scanning device itself. This allows the scanning device to be used independently of the main frame and handle, and without being limited by either of them.

[0038] For example, light projector 213 includes a single light projector unit, or it may have two or more light projector units. The light projector unit can be configured to project visible or invisible light, coherent or incoherent light. In some embodiments, the light projector unit may include one or more light sources consisting of lasers (e.g., vertical cavity surface emitter (VCSEL), edge emitter (EEL), solid-state lasers, semiconductor lasers, and / or one or more LEDs (or OLEDs)).

[0039] A light projector unit can be configured to project a structured light pattern consisting of multiple light sheets arranged side-by-side. When the light sheets are projected onto the surface of an object, they can appear as elongated light stripes. These elongated light stripes are non-intersecting and, in some embodiments, can be substantially parallel to each other. In some embodiments, the light projector unit can be a programmable light projector unit capable of projecting more than one light pattern. For example, the light projector unit can be configured to project different structured line patterns. In some embodiments, the light projector unit can emit light with wavelengths between 405 nm and 2500 nm.

[0040] In some examples, using a first camera 211 and a third camera 214, two images of an object can be captured simultaneously. Image processing can be applied, for example, to a computational method implemented by one or more processors, or to a computational method implemented, for example, by an electronic device, to derive a 3D measurement of the surface of the scanned object / object.

[0041] In some examples, the second camera 212 can capture the texture of the object while the first camera 211 and the third camera 214 are capturing images of the object, and the texture can be applied to a computational method, for example, implemented by one or more processors, or to a computational method, for example, implemented by an electronic device, to map onto a 3D measurement of the surface of the scanned object / object.

[0042] In some examples, using a membrane / film with bandpass filter functionality fixed to the lens of a camera (e.g., first camera 211, second camera 212, third camera 214) can match the wavelength of the projector units (multiple), which can help reduce light source interference from ambient light and other projector units.

[0043] In some examples, a calibration plate, such as a single plate or a set of plates whose true geometric distance values ​​have been measured in advance using high-precision methods such as photogrammetry, is used to measure the intrinsic and extrinsic parameters of the first camera 211, the second camera 212, and the third camera 214. The measurement process typically involves a series of continuous image acquisitions after adjusting the calibration plate to different positions using a scanning device, and the calculation of the spatial position and orientation of the first camera 211, the second camera 212, and the third camera 214 by identifying the positions of reference (marked) points / regions / lines in the calibration images, thereby completing the calibration of the intrinsic and extrinsic parameters of the first camera 211, the second camera 212, and the third camera 214.

[0044] It should be noted that the scanning device has its own power supply, meaning it has its own battery and can transmit signals to external devices, such as trackers, via wireless or wired means. Of course, when transmitting signals to external devices via a wired connection, the scanning device can also be powered by an external power source via a power cord.

[0045] In some embodiments, the projections of the optical component 2 and the handle 3 onto the light projection direction of the optical component 2 are perpendicular to each other.

[0046] Understandably, the optical component 2 and the handle 3 are arranged in such a way that, after installation, the projection of the optical component 2 and the handle 3 in the light projection direction of the optical component 2 forms a cross shape. This helps to improve the overall structural strength of the optical device and increases the scanning range of the optical component 2 while making it easier for the operator to hold the handle 3.

[0047] In some embodiments, refer to Figure 1 and Figure 2 The aforementioned main support structure 11 also includes multiple connecting rods 111. Adjacent fixed joints 112 are connected by connecting rods 111. A first opening is formed between at least four first connecting rods on one side of the main support structure 11, extending into the interior of the main support structure 11 to form a first mounting space 5. A second opening is formed between at least four second connecting rods on one side of the main support structure 11, extending into the interior of the main support structure 11 to form a second mounting space 6.

[0048] Understandably, the optical component 2 is installed in the first mounting space 5 through the first opening, and the handle 3 is installed in the second mounting space 6 through the second opening. In this way, both the optical component 2 and the handle 3 can be installed inside the main support structure 11, which not only provides protection for the optical component 2 and the handle 3, but also reduces the overall size of the optical device.

[0049] Among them, the aforementioned multiple fixed joints 112 are spherically distributed, and when the optical component 2 is connected to the first installation space, the optical component 2 is located within the spherical surface.

[0050] In some embodiments, the optical component 2 includes a first power source. The handle 3 includes a second power source for additionally powering the optical component 2, an interactive component for controlling the optical component 2, and a wireless component for connecting to the optical component 2.

[0051] In other words, the controller 3 is equipped with a second power source, which provides additional power to the optical component 2, extending its battery life. The capacity of the second power source can be set to be greater than that of the first power source, allowing the controller 3 to provide more power to the optical component 2, significantly prolonging its battery life. The controller 3 can control the optical component 2 through its interactive components. In some examples, the controller 3 can be connected to a first wireless component of the optical component 2, enabling data transmission between the controller 3 and an external tracker. In other examples, the optical component 2 includes a second wireless component, through which it transmits data to an external computing device such as a portable computing device, server, or head-mounted computing device. The optical component 2 can also transmit data through a communication link between the second wireless component and the first wireless component of the controller 3.

[0052] It is understandable that the controller 3 and the optical component 2 can also transmit data via a wired link such as a USB link, or use other feasible links such as PCIe, I2C, etc.

[0053] Furthermore, the aforementioned interactive component can be configured as an interactive button 311. That is, the optical component 2 can be controlled via the interactive button 311 on the controller 3.

[0054] It should be noted that the aforementioned handle 3 may also include a control device, which is connected to the second power supply, the interaction component, and the first wireless component, thereby controlling the second power supply, the interaction component, and the first wireless component to perform their respective functions. For example, refer to... Figure 5 The handle 3 includes a handle body 31 and a battery 32. The handle body 31 is provided with a battery compartment 31a for accommodating the battery 32 and a battery cover 33 covering the battery compartment 31a. The battery 32 constitutes the aforementioned second power source, enabling power supply to the optical component 2.

[0055] The aforementioned wireless components are housed within the main body 31 of the controller. The aforementioned interactive components are located on the main body 31 of the controller. In this case, the interactive components can be selected as interactive buttons 311, meaning that the optical components 2 can be controlled through button operation.

[0056] The battery 32 can be one or more, for example, two batteries 32 can be provided. The battery 32 can be selected as a 21700 battery, which can continuously power the optical component 2 and significantly extend the working time.

[0057] In some embodiments, the handle 3 is further provided with a processor and a heat dissipation component. In this case, the interaction component on the handle 3 can be selected as a touch display screen 312. That is, the handle 3 integrates a processor, which receives data, such as point cloud data and / or texture data generated by the optical component 2 scanning the object, through the first wireless component and processes it.

[0058] The processor can be selected as a high-performance computing processor.

[0059] In some examples, the handle 3 is also equipped with a heat sink to dissipate heat from the processor. This heat sink can be heat dissipation fins that contact the processor, accelerating heat dissipation through heat transfer. Alternatively, the heat sink can also consist of a fan and heat dissipation fins in contact with the processor, using airflow to accelerate heat dissipation. Of course, other methods can also be used to dissipate heat from the processor, such as heat spreaders or graphene, but these are not specifically limited here.

[0060] For example, refer to Figure 6 The handle 3 includes a handle body 31 and a battery 32. The handle body 31 is provided with a battery compartment 31a for accommodating the battery 32 and a battery cover 33 covering the battery compartment 31a. The battery 32 is configured as a second power source to provide power to the optical component 2.

[0061] The aforementioned wireless components are housed within the main body 31 of the controller. The aforementioned interactive components are located on the main body 31 of the controller. In this case, the interactive component can be selected as a touchscreen display 312. This means that the optical component 2 can be controlled via the touchscreen, enabling real-time rendering and display of the point cloud reconstruction process. Furthermore, real-time observation can be achieved through the touchscreen display 312, eliminating the need to view the screen of an external computing device.

[0062] Thus, through the processor and touch display 312, the optical device enables real-time processing and visual feedback of data from the optical component 2, improving the user experience.

[0063] In other examples, the optical component 2 includes a display screen, which allows the optical component 2 to render and display the point cloud reconstruction process based on scan data when used independently, without the need for assistance from other devices such as the handle 3.

[0064] In addition, the handle body 31 is provided with a processor cavity that houses the processor, and the handle body 31 is provided with a heat dissipation hole 31b that communicates with the processor cavity, so that the heat generated by the processor can be dissipated to the outside through the heat dissipation hole 31b.

[0065] It should be noted that the controller 3 can have at least one battery 32, such as two, to improve battery life.

[0066] In some embodiments, the optical component 2 and the main support structure 11 can be connected by snap-fit, magnetic attraction, or screws.

[0067] For example, refer to Figure 7 The optical component 2 and the main support structure 11 can be fixedly connected, for example, using screws 4. Using screws 4 not only facilitates the installation and disassembly of the optical component 2 and the main support structure 11, but also makes the connection between the optical component 2 and the main support structure 11 more stable, ensuring the connection stability between the optical component 2 and the main support structure 11 when the optical component 2, the main support structure 11 and the handle 3 are used as a whole.

[0068] In some embodiments, the handle 3 and the main support structure 11 can be selected as a snap-fit ​​connection, a magnetic connection, or a combination of the above connections.

[0069] For example, refer to Figure 7 The handle 3 and the main support structure 11 are connected by screws. Using screws not only facilitates the installation and disassembly of the optical component 2 and the main support structure 11, but also makes the connection between the handle 3 and the main support structure 11 more stable, ensuring the connection stability between the handle 3 and the main support structure 11 when the optical component 2, the main support structure 11 and the handle 3 are used as a whole.

[0070] For example, refer to Figures 1 to 7 An optical device is provided, comprising a main frame 1, an optical component 2, and a handle 3.

[0071] The aforementioned main frame 1 includes multiple targets 12 and a main support structure 11. The multiple targets 12 are located at multiple fixed joints 112 of the main support structure 11, and each target 12 includes multiple marker points. The main support structure 11 also includes a first mounting space 5 and a second mounting space 6 located on opposite sides of the main support structure 11.

[0072] The aforementioned optical component 2 is detachably connected to the first mounting space 5, and the optical component is used to perform three-dimensional scanning of the object.

[0073] The aforementioned handle 3 is detachably connected to the second mounting space 6. The optical component 2 and the handle 3 are not directly connected.

[0074] The optical component 2 is detachably connected to the main support structure 11 via screws 4. The handle 3 is also detachably connected to the main support structure 11 via screws 4.

[0075] Optical component 2 can be selected as a scanning device, such as a scanning device including a display screen or a scanning device without a display screen.

[0076] The main support structure 11 also includes multiple connecting rods 111. Adjacent fixed joints 112 are connected by connecting rods 111. At least four first connecting rods on one side of the main support structure 11 form a first opening, which extends toward the interior of the main support structure 11 to form a first installation space 5. At least four second connecting rods on one side of the main support structure 11 form a second opening, which extends toward the interior of the main support structure 11 to form a second installation space 6.

[0077] The optical component 2 includes a first power supply. The aforementioned handle 3 includes a second power supply for additional power to the optical component 2, an interactive component for controlling the optical component, and a wireless component for connecting to the optical component 2. The aforementioned handle 3 is also equipped with a processor and a heat dissipation component. In this case, the interactive component on the handle 3 can be selected as a touch screen display 312.

[0078] At this point, it can be understood that the controller 3 has two configurations. One controller 3 includes a second power supply for additional power to the optical component 2, an interaction component for controlling the optical component, and a first wireless component for connecting the optical component 2. The other controller includes a second power supply for additional power to the optical component 2, an interaction component for controlling the optical component, a first wireless component for connecting the optical component 2 and / or an external computing device, and also includes a processor and a heat dissipation component. In this case, the interaction component can be selected as a touch screen display 312.

[0079] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
