[0069] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0070] This application aims to address at least one of the technical problems existing in related technologies. To this end, this application proposes an image acquisition component and a tracking 3D scanner, which helps the tracking 3D scanner adapt to different working scenarios.

[0071] The following is for reference. Figures 1-12 The image acquisition component 10 according to an embodiment of this application is described.

[0072] like Figure 1 As shown, the image acquisition component 10 is applied to the tracking 3D scanner 1. The image acquisition component 10 includes: a skeleton 20, a sensor 40, a heat insulation component 50, and a laser component 60. The sensor 40 is mounted on the skeleton 20, and its transceiver ends face the first direction X. The heat insulation component 50 is mounted on the skeleton 20. The laser component 60 is mounted on the side of the heat insulation component 50 away from the skeleton 20, and its transceiver ends face the first direction X of the skeleton 20.

[0073] The image acquisition component 10 is the main body of the tracking 3D scanner 1. It is mainly used to acquire image information of the target object to help the tracking 3D scanner 1 achieve accurate 3D modeling and positioning. The image acquisition component 10 is covered by a shell 30, which protects the internal structure and components and reduces the influence of the external environment on the tracking 3D scanner. At the same time, the shell 30 can form a grip 310, and a trigger part 311 is provided in the area adjacent to the grip 310.

[0074] In this embodiment, the image acquisition component 10 may include a frame 20, a sensor 40, a heat insulation component 50, and a laser component 60. The frame 20 is the main support structure of the image acquisition component 10, which plays the role of supporting each core component to maintain the overall structural stability of the image acquisition component 10. The sensor 40, the heat insulation component 50, and the laser component 60 are all installed on the frame 20.

[0075] For example, the skeleton 20 is made of metal and the outer shell 30 is made of plastic, with the plastic outer shell 30 covering the outside of the metal skeleton 20.

[0076] like Figure 1 As shown, sensor 40 is mounted on frame 20, and the transceiver end of sensor 40 faces the first direction X. Taking sensor 40 located on the front side of frame 20 as an example, the first direction X is defined as the direction from back to front.

[0077] Sensor 40 is mainly used to receive scanning data such as reflected light signals from the surface of an object, or for other functions such as ranging and image capture. The specific function depends on the type of sensor 40, such as laser sensor 40 or camera sensor 40.

[0078] The sensor 40 typically has two main parts: the body and the transceiver terminal for receiving signals. The transceiver terminal of the sensor 40 is mainly used to capture light signals reflected from the surface of the object. The transceiver terminal of the sensor 40 faces the first direction X, which can effectively reduce the risk of the sensor 40 receiving interference signals from multiple directions at the same time, thereby reducing measurement errors.

[0079] The heat insulation component 50 is a component used to isolate heat. It is mainly used to isolate the heat generated by the laser component 60 or other high-temperature components from the frame 20 when they are working, thereby reducing the impact of heat accumulation on the strength of the frame 20. The laser component 60 is a device for emitting laser signals. The laser signals are used to measure the spatial position or shape of the target object and are returned to be received by the sensor 40. The transmitting and receiving ends of the laser component 60 and the transmitting and receiving ends of the sensor 40 are oriented in the same direction.

[0080] For example, the insulation element 50 is typically made of a material with low thermal conductivity, such as ceramics, rubber or certain polymer materials.

[0081] For example, the laser component 60 may include a laser emitter, the sensor 40 may be a laser sensor 40, and the laser emitter and the laser receiver are oriented in the same direction.

[0082] In actual operation, the laser component 60 emits a laser signal in the first direction X. After the laser signal reaches the surface of the object to be measured, it is reflected. The sensor 40 receives the reflected laser signal, thereby realizing the scanning of the object.

[0083] In some embodiments, the heat insulation element 50 and the laser assembly 60 can be arranged in various ways, including but not limited to:

[0084] Example 1: The heat insulation component 50 and the laser assembly 60 are both mounted on the first side 201 of the frame 20.

[0085] like Figure 2 and Figure 3 As shown, the heat insulation component 50 is installed on the first side 201 of the frame 20, and the normal of the first side 201 intersects the first direction X. The laser component 60 is installed on the side of the heat insulation component 50 away from the frame 20, and the transmitting and receiving ends face the first direction X of the frame 20.

[0086] The heat insulation component 50 is installed on the first side 201 of the frame 20, and the normal of the first side 201 intersects the first direction X. That is, the side of the frame 20 where the sensor 40 is located is adjacent to the first side 201 of the frame 20 where the heat insulation component 50 is located. The laser component 60 is installed on the side of the heat insulation component 50 away from the frame 20. That is, the heat insulation component 50 is provided between the laser component 60 and the frame 20.

[0087] Example 2: Both the heat insulation component 50 and the laser assembly 60 are mounted on the second side 202 of the frame 20.

[0088] The heat insulation component 50 is installed on the second side 202 of the frame 20, and the normal of the second side 201 is parallel to the first direction X. The laser component 60 is installed on the side of the heat insulation component 50 away from the frame 20, and the transmitting and receiving ends face the first direction X of the frame 20.

[0089] The heat insulation component 50 is installed on the second side 202 of the frame 20, and the normal of the second side 201 is parallel to the first direction X. That is, the side of the frame 20 where the sensor 40 is located is adjacent to the first side 201 of the frame 20 where the heat insulation component 50 is located. The laser component 60 is installed on the side of the heat insulation component 50 away from the frame 20. That is, the heat insulation component 50 is provided between the laser component 60 and the frame 20.

[0090] In addition, the sensor 40 is located at both ends of the skeleton 20 along its length, and the laser component 60 is located in the middle of the skeleton 20. The laser component 60 and the sensor 40 are spaced apart from each other, which can reduce mutual signal interference, thereby improving the efficiency of signal transmission and reception. It can also acquire three-dimensional data of the scanned object from all directions and multiple angles, thereby improving measurement accuracy.

[0091] Trackers are typically used to precisely locate and track the movement of objects. In related technologies, trackers are usually mounted and fixed on a tripod. The tracker's position is fixed, its function is relatively simple, and there is room for improvement.

[0092] This application adds a laser component 60 to the image acquisition component 10 of the tracking 3D scanner 1. The tracking 3D scanner 1 can be operated handheld independently of the original fixed installation method, and scans the surface of the object while monitoring the precise position and movement of the object, thereby constructing a complete 3D model of the object. This helps the tracking 3D scanner 1 adapt to different working scenarios and perform more flexible tracking and measurement.

[0093] According to the image acquisition component 10 provided in the embodiments of this application, by adding a laser component 60 to the image acquisition component 10, handheld function can be integrated into the tracking 3D scanner 1. At the same time, while monitoring the precise position and movement of the object, a complete 3D model of the object can be constructed, which helps to adapt to different working scenarios and perform more flexible tracking and measurement.

[0094] In some embodiments, such as Figure 3 As shown, the laser assembly 60 includes a laser 610 and a base 620. The laser 610 is mounted on the base 620, the base 620 is mounted on the frame 20, and the heat insulation member 50 is clamped between the base 620 and the frame 20.

[0095] In this embodiment, the laser 610 is the core part of the laser assembly 60. The laser 610 is mainly used to generate a laser beam. The base 620 is the support structure of the laser 610, which is usually used to fix the laser 610 and keep it stable.

[0096] For example, the laser 610 may include a laser source, a laser gain medium, and a laser resonant cavity, etc. The laser source is used to generate a laser signal, and the laser gain medium and the laser resonant cavity are used to amplify the laser signal.

[0097] During installation, the laser 610 is first installed on the base 620, then the heat insulation component 50 is fixed to the frame 20, and then the base 620 is installed on the frame 20, with the heat insulation component 50 clamped between the base 620 and the frame 20. The laser assembly 60 and the frame 20 are respectively connected to both sides of the heat insulation component 50.

[0098] Understandably, the base 620 can provide a stable support platform for the laser 610, reducing the impact of mechanical disturbances on the performance of the laser 610. Mounting the laser 610 on the base 620, which is connected to the frame 20, can reduce the positional displacement or damage of the laser 610 caused by vibration or external impact.

[0099] In some embodiments, such as Figure 3 and Figure 4 As shown, the first side 201 of the frame 20 has a mounting platform 210, the mounting platform 210 forms a receiving groove 220, the heat insulation member 50 is installed in the receiving groove 220, the seat 620 is installed on the mounting platform 210, and the heat insulation member 50 is clamped between the bottom of the receiving groove 220 and the seat 620.

[0100] In this embodiment, the first side 201 of the frame 20 has an outwardly protruding mounting platform 210. The mounting platform 210 is mainly used to provide a stable mounting platform for the laser assembly 60 and the heat insulation component 50. The mounting platform 210 is formed with a receiving groove 220 for mounting the heat insulation component 50. The heat insulation component 50 matches the shape of the receiving groove 220, and the receiving groove 220 can securely mount the heat insulation component 50 in a specific position.

[0101] The two ends of the upper side of the seat 620 are higher than the middle part of the upper side of the seat 620 in the height direction, and the two ends of the upper side of the seat 620 are connected to the mounting platform 210. The middle part of the upper side of the seat 620 is connected to the heat insulation component 50. When the two ends of the upper side of the seat 620 abut against the mounting platform 210, the middle part of the upper side of the seat 620 and the receiving groove 220 together provide an installation position for the heat insulation component 50, and clamp the heat insulation component 50 between the bottom of the receiving groove 220 and the middle part of the upper side of the seat 620.

[0102] It is understandable that clamping the heat insulation component 50 between the bottom of the receiving groove 220 and the base 620 can reduce the displacement of the heat insulation component 50 during operation and effectively isolate the heat transfer between the laser component 60 and the frame 20.

[0103] In some embodiments, such as Figure 3 and Figure 6 As shown, the bottom of the receiving groove 220 is provided with a first positioning structure 221, and the heat insulation member 50 is provided with a second positioning structure 510 for positioning and cooperating with the first positioning structure 221.

[0104] In this embodiment, the heat insulation component 50 is clamped between the bottom of the receiving groove 220 and the base 620. The upper side of the heat insulation component 50 contacts the bottom of the receiving groove 220, and the lower side of the heat insulation component 50 contacts the base 620. The bottom of the receiving groove 220 is provided with a first positioning structure 221, and the upper side of the heat insulation component 50 is provided with a second positioning structure 510. The first positioning structure 221 and the second positioning structure 510 are positioned and cooperated to accurately install the heat insulation component 50 in the designated position.

[0105] For example, the first positioning structure 221 and the second positioning structure 510 can be grooves, protrusions, holes or other types of positioning structures.

[0106] There are multiple first positioning structures 221 and second positioning structures 510, and the first positioning structures 221 and second positioning structures 510 are positioned and matched in a one-to-one correspondence.

[0107] Furthermore, the first positioning structure 221 and the second positioning structure 510 have various structural forms, including but not limited to:

[0108] Example 1: The first positioning structure 221 is a protrusion, and the second positioning structure 510 is a groove.

[0109] The first positioning structure 221 and the second positioning structure 510 are positioned and engaged, with at least a portion of the first positioning structure 221 extending into the second positioning structure 510.

[0110] Example 2: The first positioning structure 221 is a groove, and the second positioning structure 510 is a protrusion.

[0111] The first positioning structure 221 and the second positioning structure 510 are positioned and engaged, with at least a portion of the second positioning structure 510 extending into the first positioning structure 221.

[0112] It is understandable that the positioning cooperation of the first positioning structure 221 and the second positioning structure 510 can effectively reduce the installation error of the heat insulation component 50 and accurately install the heat insulation component 50 in the receiving groove 220.

[0113] In some embodiments, such as Figure 3 As shown, one of the second positioning structures 510 is provided with a through hole 520, the frame 20 is provided with a first connecting hole 230 that extends through to the bottom of the receiving groove 220, the seat 620 is provided with a second connecting hole 630, and the seat 620, the heat insulation member 50 and the frame 20 are connected by a connector that extends through the second connecting hole 630, the through hole 520 and the first connecting hole 230.

[0114] In this embodiment, one of the multiple second positioning structures 510 located on the upper side of the heat insulation member 50 is provided with a through hole 520, the bottom of the receiving groove 220 of the frame 20 is provided with a first connecting hole 230, and the seat body 620 is provided with a second connecting hole 630. The through hole 520 penetrates the heat insulation member 50 along the normal direction of the heat insulation member 50, the first connecting hole 230 penetrates the frame 20 along the normal direction of the heat insulation member 50, and the second connecting hole 630 penetrates the seat body 620 along the normal direction of the heat insulation member 50. The projections of the through hole 520, the first connecting hole 230, and the second connecting hole 630 along the normal direction of the heat insulation member 50 coincide.

[0115] The base 620, the heat insulation component 50 and the frame 20 are connected by a connector, and the connector passes through the second connecting hole 630, the through hole 520 and the first connecting hole 230 from bottom to top, thereby connecting the base 620, the heat insulation component 50 and the frame 20 into a whole.

[0116] For example, when the second positioning structure 510 is a protrusion, one of the second positioning structures 510 is provided with a through hole 520, that is, one end of the through hole 520 is located on the upper surface of the protrusion; when the second positioning structure 510 is a groove, one of the second positioning structures 510 is provided with a through hole 520, that is, one end of the through hole 520 is located at the bottom of the groove.

[0117] It is understandable that the base 620, the heat insulation component 50 and the frame 20 are connected by a connector that passes through the second connecting hole 630, the through hole 520 and the first connecting hole 230, so that the base 620, the heat insulation component 50 and the frame 20 can be firmly connected.

[0118] In some embodiments, such as Figure 3 As shown, the seat 620 is provided with a third positioning structure 640, and the heat insulation member 50 is provided with a fourth positioning structure for positioning and cooperating with the third positioning structure 640.

[0119] In this embodiment, the upper side of the seat 620 is provided with a third positioning structure 640, the upper side of the heat insulation member 50 is provided with a second positioning structure 510 that positions and cooperates with the first positioning structure 221 on the frame 20, and the lower side of the heat insulation member 50 is provided with a fourth positioning structure that positions and cooperates with the third positioning structure 640 on the seat 620.

[0120] For example, the third positioning structure 640 and the fourth positioning structure can be grooves, protrusions, holes or other types of positioning structures.

[0121] There are multiple third positioning structures 640 and fourth positioning structures, and the third positioning structures 640 and fourth positioning structures are positioned and matched in a one-to-one correspondence.

[0122] Furthermore, the third positioning structure 640 and the fourth positioning structure have various structural forms, including but not limited to:

[0123] Example 1: The third positioning structure 640 is a protrusion, and the fourth positioning structure is a groove.

[0124] The third positioning structure 640 is positioned and engaged with the fourth positioning structure, with at least a portion of the third positioning structure 640 extending into the fourth positioning structure.

[0125] Example 2: The third positioning structure 640 is a groove, and the fourth positioning structure is a protrusion.

[0126] The third positioning structure 640 is positioned and engaged with the fourth positioning structure, with at least a portion of the fourth positioning structure extending into the third positioning structure 640.

[0127] Understandably, the positioning cooperation between the third positioning structure 640 and the fourth positioning structure can effectively reduce the installation error of the seat 620 and accurately install the seat 620 onto the heat insulation component 50.

[0128] In some embodiments, such as Figure 2 As shown, the sensor 40 includes a lens 410 and a sensor plate 420. The lens 410 and the sensor plate 420 are respectively mounted on the second side 202 and the third side 203 of the frame 20, and the second side 202 and the third side 203 are arranged opposite to each other along the first direction X. The lens 410 faces the first direction X.

[0129] In this embodiment, the sensor 40 may include a lens 410 and a sensor plate 420. The lens 410 is a key component of the sensor 40, mainly used to capture light and transmit image signals to the sensor plate 420. The sensor plate 420 is used to receive the light signals transmitted from the lens 410 and convert them.

[0130] For example, sensor board 420 typically consists of photosensitive elements and circuitry that can convert optical signals into digital or analog signals for further processing.

[0131] The lens 410 and the sensor board 420 are respectively mounted on the second side 202 and the third side 203 of the frame 20, and the second side 202 and the third side 203 are arranged opposite to each other along the first direction X, wherein the second side 202 of the frame 20 faces the first direction X, and the third side 203 of the frame 20 faces away from the first direction X.

[0132] It is understandable that the lens 410 and the sensor plate 420 are respectively mounted on the second side 202 and the third side 203 of the frame 20, so that the lens 410 can face the first direction X and maintain a stable relative position with the sensor plate 420, thereby reducing the relative offset between the lens 410 and the sensor plate 420, improving the accuracy of image acquisition, and effectively reducing signal distortion caused by improper installation.

[0133] In some embodiments, such as Figure 9 As shown, the end of the frame 20 forms a mounting base 240, which has a through hole 250 extending along the first direction X. The lens 410 and the sensor plate 420 are respectively mounted on both sides of the mounting base 240 and are electrically connected through a cable passing through the through hole 250.

[0134] In this embodiment, the length direction of the skeleton 20 is defined as the second direction Y, which intersects with the first direction X. The skeleton 20 forms mounting bases 240 at both ends along the second direction Y. The sensor 40 is mounted on the mounting base 240, and the mounting base 240 has a through hole 250 extending along the first direction X. The lens 410 and the sensor plate 420 are respectively mounted on both sides of the mounting base 240, and at least a portion of the through hole 250, the lens 410, and the sensor plate 420 are aligned along the first direction X.

[0135] Mounting base 240 has specific dimensions and shape for precisely positioning lens 410 and sensor plate 420 and maintaining lens 410 and sensor plate 420 in a stable relative position during operation. Through hole 250 is mainly used for cable routing, and lens 410 and sensor plate 420 are electrically connected through cable passing through through hole 250.

[0136] Understandably, using a cable passing through the through-hole 250 to achieve electrical connection between the lens 410 and the sensor board 420 simplifies wiring.

[0137] In some embodiments, such as Figure 9As shown, the through hole 250 includes a limiting hole 251 provided on the third side 203. The limiting hole 251 is a non-rotating body. The sensor plate 420 has a positioning protrusion 421, which extends into the limiting hole 251.

[0138] In this embodiment, the through hole 250 penetrates the mounting base 240 along the first direction X, and the through hole 250 forms a limiting hole 251 on the side of the mounting base 240 where the sensor plate 420 is mounted. The limiting hole 251 is a non-rotating body, while the other part of the through hole 250 is a rotating body. The sensor plate 420 has a positioning protrusion 421, which has the same shape as the limiting hole 251, and the positioning protrusion 421 extends into the limiting hole 251 for positioning and engagement.

[0139] For example, the positioning protrusion 421 and the limiting hole 251 can be polygonal, elliptical or other irregular shapes, thereby reducing the rotation or unnecessary movement of the parts.

[0140] Understandably, the positioning protrusion 421 on the sensor plate 420 and the positioning hole 251 of the non-rotating body are positioned and engaged, which helps to limit the degree of freedom of the sensor plate 420 during installation and reduce improper rotation or displacement.

[0141] In some embodiments, such as Figure 9 As shown, the skeleton 20 is hollow inside.

[0142] In this embodiment, the frame 20 forms mounting bases 240 at both ends along the second direction Y, and the middle part of the frame 20 adopts a tubular structure to form a hollow frame 20. The hollow frame 20 helps to reduce the weight of the overall structure and reduce production costs.

[0143] Meanwhile, hollow structures can improve strength and rigidity through reasonable structural design. For example, a honeycomb structure can be formed inside the skeleton 20 or a reinforcing rib 260 can be set, which can provide sufficient compressive or bending resistance while maintaining lightweight.

[0144] In addition, the hollow frame 20 can provide installation space for other components. For example, cables can be installed inside the frame 20 to form a cable routing channel.

[0145] It should be noted that the middle part of the frame 20 is a tubular structure. The tubular structure can be obtained by profile processing. Only the two ends of the frame 20 are precision-machined, which can simplify the processing technology of the frame 20 and reduce the processing cost of the frame 20.

[0146] Understandably, the hollow internal frame 20 helps reduce the weight of the overall structure and lower production costs.

[0147] In some embodiments, such as Figure 7As shown, the skeleton 20 is provided with a plurality of reinforcing ribs 260, which extend along the length of the skeleton 20 and are distributed at intervals.

[0148] In this embodiment, the third side 203 of the frame 20 is provided with a plurality of reinforcing ribs 260. The reinforcing ribs 260 can be used to enhance strength and rigidity, thereby improving the load-bearing capacity of the frame 20 and reducing the risk of deformation of the frame 20.

[0149] Multiple reinforcing ribs 260 extend along the second direction Y and are spaced apart along the normal direction of the heat insulation member 50. The normal direction of the heat insulation member 50 intersects with the second direction Y. The extension of the reinforcing ribs 260 along the second direction Y can evenly disperse stress when subjected to external force. The spaced distribution of the reinforcing ribs 260 along the normal direction of the heat insulation member 50 can reduce the risk of stress concentration.

[0150] In addition, the reinforcing ribs 260 on the hollow frame 20 can reduce weight while maintaining strength. At the same time, the reinforcing ribs 260 can effectively enhance the structure's resistance to bending, shearing and torsion. On the elongated frame 20, the reinforcing ribs 260 can reduce the risk of excessive deformation or bending in the middle of the frame 20.

[0151] Understandably, setting multiple reinforcing ribs 260 on the frame 20 can improve the load-bearing capacity of the frame 20 and reduce the risk of deformation of the frame 20.

[0152] This application also provides a tracking-type 3D scanner 1, such as... Figure 1 As shown, the tracking 3D scanner 1 includes an image acquisition component 10 and a housing 30. The housing 30 covers the skeleton 20 of the image acquisition component 10 to form a grip 310, and a trigger part 311 is provided in the area adjacent to the grip 310.

[0153] The image acquisition component 10 includes: a frame 20, a sensor 40, a heat insulation component 50, and a laser component 60. The sensor 40 is mounted on the frame 20 with its transceiver end facing the first direction X. The heat insulation component 50 is mounted on the first side 201 of the frame 20, and the normal of the first side 201 intersects the first direction X. The laser component 60 is mounted on the side of the heat insulation component 50 away from the frame 20, and its transceiver end faces the first direction X of the frame 20.

[0154] The image acquisition component 10 is mainly used to acquire image information of the target object, which helps the tracking 3D scanner 1 to achieve accurate 3D modeling and positioning. The image acquisition component 10 is covered by a shell 30, which protects the internal structure and components and reduces the impact of the external environment on the tracking 3D scanner.

[0155] The housing 30 can form a grip 310, which has an ergonomic design to help the device maintain balance and a comfortable grip. At the same time, a trigger 311 is provided in the area adjacent to the grip 310 to facilitate operations such as taking pictures during scanning.

[0156] In this embodiment, the image acquisition component 10 may include a frame 20, a sensor 40, a heat insulation component 50, and a laser component 60. The frame 20 is the main support structure of the image acquisition component 10, which plays the role of supporting each core component to maintain the overall structural stability of the image acquisition component 10. The sensor 40, the heat insulation component 50, and the laser component 60 are all installed on the frame 20.

[0157] For example, the skeleton 20 is made of metal and the outer shell 30 is made of plastic, with the plastic outer shell 30 covering the outside of the metal skeleton 20.

[0158] like Figure 1 As shown, sensor 40 is mounted on frame 20, and the transceiver end of sensor 40 faces the first direction X. Taking sensor 40 located on the front side of frame 20 as an example, the first direction X is defined as the direction from back to front.

[0159] Sensor 40 is mainly used to receive scanning data such as reflected light signals from the surface of an object, or for other functions such as ranging and image capture. The specific function depends on the type of sensor 40, such as laser sensor 40 or camera sensor 40.

[0160] The sensor 40 typically has two main parts: the body and the transceiver terminal for receiving signals. The transceiver terminal of the sensor 40 is mainly used to capture light signals reflected from the surface of the object. The transceiver terminal of the sensor 40 faces the first direction X, which can effectively reduce the risk of the sensor 40 receiving interference signals from multiple directions at the same time, thereby reducing measurement errors.

[0161] The heat insulation component 50 is a component used to isolate heat. It is mainly used to isolate the heat generated by the laser component 60 or other high-temperature components from the frame 20 when they are working, thereby reducing the impact of heat accumulation on the strength of the frame 20. The laser component 60 is a device for emitting laser signals. The laser signals are used to measure the spatial position or shape of the target object and are returned to be received by the sensor 40. The transmitting and receiving ends of the laser component 60 and the transmitting and receiving ends of the sensor 40 are oriented in the same direction.

[0162] For example, the insulation element 50 is typically made of a material with low thermal conductivity, such as ceramics, rubber or certain polymer materials.

[0163] For example, the laser component 60 may include a laser emitter, the sensor 40 may be a laser sensor 40, and the laser emitter and the laser receiver are oriented in the same direction.

[0164] In actual operation, the laser component 60 emits a laser signal in the first direction X. After the laser signal reaches the surface of the object to be measured, it is reflected. The sensor 40 receives the reflected laser signal, thereby realizing the scanning of the object.

[0165] In some embodiments, the heat insulation element 50 and the laser assembly 60 can be arranged in various ways, including but not limited to:

[0166] Example 1: The heat insulation component 50 and the laser assembly 60 are both mounted on the first side 201 of the frame 20.

[0167] like Figure 2 and Figure 3 As shown, the heat insulation component 50 is installed on the first side 201 of the frame 20, and the normal of the first side 201 intersects the first direction X. The laser component 60 is installed on the side of the heat insulation component 50 away from the frame 20, and the transmitting and receiving ends face the first direction X of the frame 20.

[0168] The heat insulation component 50 is installed on the first side 201 of the frame 20, and the normal of the first side 201 intersects the first direction X. That is, the side of the frame 20 where the sensor 40 is located is adjacent to the first side 201 of the frame 20 where the heat insulation component 50 is located. The laser component 60 is installed on the side of the heat insulation component 50 away from the frame 20. That is, the heat insulation component 50 is provided between the laser component 60 and the frame 20.

[0169] Example 2: Both the heat insulation component 50 and the laser assembly 60 are mounted on the second side 202 of the frame 20.

[0170] The heat insulation component 50 is installed on the second side 202 of the frame 20, and the normal of the second side 201 is parallel to the first direction X. The laser component 60 is installed on the side of the heat insulation component 50 away from the frame 20, and the transmitting and receiving ends face the first direction X of the frame 20.

[0171] The heat insulation component 50 is installed on the second side 202 of the frame 20, and the normal of the second side 201 is parallel to the first direction X. That is, the side of the frame 20 where the sensor 40 is located is adjacent to the first side 201 of the frame 20 where the heat insulation component 50 is located. The laser component 60 is installed on the side of the heat insulation component 50 away from the frame 20. That is, the heat insulation component 50 is provided between the laser component 60 and the frame 20.

[0172] In addition, the sensor 40 is located at both ends of the skeleton 20 along its length, and the laser component 60 is located in the middle of the skeleton 20. The laser component 60 and the sensor 40 are spaced apart from each other, which can reduce mutual signal interference, thereby improving the efficiency of signal transmission and reception. It can also acquire three-dimensional data of the scanned object from all directions and multiple angles, thereby improving measurement accuracy.

[0173] Trackers are typically used to precisely locate and track the movement of objects. In related technologies, trackers are usually mounted and fixed on a tripod. The tracker's position is fixed, its function is relatively simple, and the existing tracker image acquisition component 10 has a single function and cannot support the addition of other functional modules to the device, leaving room for improvement.

[0174] This application adds a laser component 60 to the image acquisition component 10 of the tracking 3D scanner 1. The tracking 3D scanner 1 can be operated handheld independently of the original fixed installation method, and scans the surface of the object while monitoring the precise position and movement of the object, thereby constructing a complete 3D model of the object. This helps the tracking 3D scanner 1 adapt to different working scenarios and perform more flexible tracking and measurement.

[0175] According to the tracking 3D scanner 1 provided in the embodiments of this application, by adding a laser component 60 to the image acquisition component 10 of the tracking 3D scanner 1, a handheld function can be integrated into the tracking 3D scanner 1. At the same time, while monitoring the precise position and movement of the object, a complete 3D model of the object can be constructed, which helps to adapt to different working scenarios and perform more flexible tracking and measurement.

[0176] In some embodiments, such as Figure 10 and Figure 12 As shown, the tracking 3D scanner 1 may also include a limiting member 80, which is installed at both ends of the housing 30 along the second direction Y to limit the fingers, and the second direction Y intersects the first direction X.

[0177] In this embodiment, the limiting member 80 includes, but is not limited to, a strap 830, a finger rest, or an anti-slip structure, and is mainly used to restrict the fingers and distribute grip pressure while guiding the fingers to be placed naturally.

[0178] For example, the limiting member 80 may include a strap 830, and the front shell assembly 330 is provided with a first strap buckle 810 at both ends along the second direction Y, and the side shell assembly 350 is provided with a second strap buckle 820 at one end away from the first strap buckle 810, and the strap connects between the first strap buckle 810 and the second strap buckle 820.

[0179] The strap 830 is installed between the first strap buckle 810 and the second strap buckle 820, wherein the first strap buckle 810 is installed on the front shell assembly 330 and the second strap buckle 820 is installed on the side shell assembly 350.

[0180] The front shell assembly 330 is provided with a first strap buckle 810 at both ends along the second direction Y, and the side shell assembly 350 is provided with a second strap buckle 820 at the end away from the first strap buckle 810. After the strap 830 is installed, the strap 830 forms a limiting structure at both ends of the tracking 3D scanner 1 along the second direction Y, which can provide protection for the user when hand-held scanning.

[0181] Understandably, the limiting component 80 is installed at both ends of the housing 30 along the second direction Y, which can provide protection for the user when hand-held scanning.

[0182] In some embodiments, such as Figure 11 As shown, the trigger part 311 is positioned near the limiting member 80.

[0183] In this embodiment, the housing 30 may form a grip portion 310, and a trigger portion 311 is arranged on the side of the housing 30 that is directly opposite to the first side 201 in the area adjacent to the grip portion 310. At the same time, the trigger portions 311 are spaced apart along the second direction Y, and the trigger portions 311 are disposed adjacent to the limiting member 80.

[0184] In addition, the trigger unit 311 is electrically connected to the laser component 60, which can perform operations such as taking pictures during the scanning process. At the same time, the side where the trigger unit 311 is located is adjacent to the second side 202, and the sensor 40 is installed on the second side 202 of the frame 20, while the laser component 60 is installed on the first side 201 of the frame 20. That is, the trigger unit 311, the sensor 40, and the laser component 60 are facing different directions, which makes it convenient for operators to adjust and control.

[0185] Understandably, the trigger unit 311, as part of the user interface, is positioned near the limit member 80 to facilitate user control of the device's operating status.

[0186] In some embodiments, such as Figure 11 As shown, the tracking 3D scanner 1 also includes a tail plug assembly 70, which is arranged on the first side 201 of the skeleton 20. The normal of the first side 201 intersects the first direction X, and the tail plug assembly 70 is electrically connected to the laser assembly 60 and the circuit board 342.

[0187] In this embodiment, the tail plug assembly 70 is arranged on the first side 201 of the frame 20 and is electrically connected to the laser assembly 60 and the circuit board 342 respectively. When the laser assembly 60 is installed on the first side 201 of the frame 20, the tail plug assembly 70 is arranged on the side of the laser assembly 60 away from the frame 20. When the laser assembly 60 is installed on the second side 202 of the frame 20, the tail plug assembly 70 is arranged on the side of the laser assembly 60 facing the first side 201 of the frame 20.

[0188] Understandably, the tail plug assembly 70 can isolate the laser assembly 60 from the circuit board 342, while allowing electrical signals to be transmitted between the laser assembly 60 and the circuit board 342.

[0189] In some embodiments, such as Figure 11 As shown, the tail plug assembly 70 may include a tail plug plate 710 and a heat insulation block 720. The tail plug plate 710 is installed on the side of the laser assembly 60 away from the frame 20, and the heat insulation block 720 is installed on the side of the tail plug plate 710 away from the laser assembly 60.

[0190] In this embodiment, the tail plug assembly 70 may include a tail plug plate 710, a heat insulation block 720, and a quick-release plate fixing seat 730, wherein the tail plug plate 710 is installed on the upper part of the heat insulation block 720, and the heat insulation block 720 is installed on the quick-release plate fixing seat 730.

[0191] The laser assembly 60 is electrically connected to the tail plug plate 710, and the tail plug plate 710 is electrically connected to the circuit board 342. The tail plug plate 710 can transmit electrical signals between the laser assembly 60 and the circuit board 342.

[0192] Understandably, the heat insulation block 720 can reduce heat transfer between the laser component 60 and the circuit board 342, and also reduce the impact of external temperature on the frame 20.

[0193] In some embodiments, such as Figure 1 As shown, the outer shell 30 may include a main shell 320, a front shell assembly 330, a rear shell assembly 340, and a side shell assembly 350. The rear shell assembly 340 is mounted on the side of the main shell 320 away from the frame 20 along the first direction X. The main shell 320 and the front shell assembly 330 are arranged opposite each other along the first direction X. The side shell assembly 350 is arranged opposite each other along the second direction Y. The second direction Y and the normal of the first side 201 intersect the first direction X in pairs.

[0194] In this embodiment, the outer shell 30 is assembled from multiple components. The outer shell 30 may include a main shell 320, a front shell assembly 330, a rear shell assembly 340, and a side shell assembly 350. The rear shell assembly 340, the main shell 320, and the front shell assembly 330 are arranged opposite each other along a first direction X, and the side shell assembly 350 is arranged opposite each other along a second direction Y. The second direction Y and the normal of the first side surface 201 intersect the first direction X in pairs.

[0195] The main housing 320 and the front housing assembly 330 are spliced ​​together in the first direction X. The side housing assembly 350 is spliced ​​together with the main housing 320 and the front housing assembly 330 respectively. The main housing 320, the front housing assembly 330 and the side housing assembly 350 together form a cavity, and the image acquisition assembly 10 is installed in the cavity.

[0196] Furthermore, the rear shell assembly 340 is detachably mounted on the side of the main shell 320 away from the front shell assembly 330 along the first direction X, that is, the rear shell assembly 340 is mounted on the outside of the main shell 320.

[0197] Understandably, the main housing 320, the front housing assembly 330, the rear housing assembly 340, and the side housing assembly 350 form a cavity for accommodating the image acquisition assembly 10.

[0198] In some embodiments, such as Figure 1 As shown, a circuit board 342 is mounted on the side of the rear housing assembly 340 facing the main housing 320.

[0199] In this embodiment, a circuit board 342 is provided between the rear shell assembly 340 and the main shell 320, and the circuit board 342 and the rear shell assembly 340 can be assembled and disassembled as a module, which facilitates maintenance and replacement.

[0200] Furthermore, mounting the circuit board 342 on the rear housing assembly 340 can maximize the use of the internal space of the housing 30, while effectively reducing interference between the circuit board 342 and other sensitive components.

[0201] In some embodiments, such as Figure 10 As shown, a heat sink 341 is provided on the side of the rear shell assembly 340 away from the main shell 320.

[0202] In this embodiment, a heat sink 341 is provided on the side of the rear housing assembly 340 away from the main housing 320, and a circuit board 342 can be installed on the side of the rear housing assembly 340 facing the main housing 320. The heat sink 341 can be used to dissipate heat for the circuit board 342.

[0203] For example, the heat sink 341 may include fins to increase the surface area in contact with air, thereby improving the efficiency of heat conduction.

[0204] Understandably, heat sink 341 helps improve the heat dissipation efficiency of the device under high load and reduces the risk of device failure due to overheating.

[0205] In some embodiments, such as Figure 12 As shown, the second side 202 of the skeleton 20 is provided with an indicator 90, the transceiver end of the indicator 90 is oriented toward the first direction X, and is used to project an indicator laser during scanning.
