It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0040] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some of the embodiments of the present application, not all the embodiments.

[0041] The hand-held three-dimensional detection device according to the embodiments of the present application will be described below in combination with the accompanying drawings.

[0042] The hand-held three-dimensional detection device according to the embodiments of the present application can be applied to overhead line system foundation bolt measurement, wherein the measurement includes the length of the exposed bolt and the distance between the bolts.

[0044] The shell 10 is provided with a mounting cavity (not shown in the figure), and the shell 10 is provided with at least one window 101 which is in communication with the outside and the mounting cavity.

[0045] Optionally, a power module can be provided inside the shell 10 to power the electrical components in the handheld three-dimensional detection device (for example, the RTK component 12, the information acquisition mechanism 13, the control board 14, the processor 15, etc.), or a power supply socket 102 for connecting to an external battery pack can be provided on the shell 10, and the power supply socket 102 can be electrically connected to the electrical components in the handheld three-dimensional detection device respectively.

[0046] It should be noted that the power socket 102 described in this embodiment can be an aviation plug, which has the characteristics of high reliability, strong anti-interference ability and long service life. It not only ensures the stability and safety of power transmission, but also makes the connection with the external battery pack more convenient and firm, thereby improving the user experience. Moreover, by connecting the external battery pack through the power socket 102, it can be used in an environment without a fixed power supply, which greatly improves the portability of the handheld three-dimensional detection device.

[0047] The cover 11 is detachably connected to the housing 10 .

[0048] Optionally, the cover 11 can be fixed to the housing 10 by various means such as bolt connection, snap connection or magnetic connection, wherein, reference can be made to Figure 1 As shown, taking a threaded connection as an example, a clear hole is formed on the cover 11 and a threaded hole is formed on the housing 10. By passing a bolt through the clear hole of the cover 11 and screwing it into the threaded hole of the housing 10, the cover 11 can be firmly fixed. When the cover 11 needs to be removed, the bolt can be simply rotated to gradually disengage the threaded hole, and the cover 11 can be easily separated from the housing 10. The operation is simple and quick.

[0049] The RTK component 12 is mounted on the cover 11 and is used to measure the position coordinates of the target object.

[0050] It should be noted that the target object described in this embodiment may refer to the contact network foundation anchor bolts and the base connected thereto. For example, the target object below is illustrated by the contact network foundation anchor bolts and the base.

[0051] Furthermore, the RTK component 12 includes an RTK module 120 and an RTK antenna 121 .

[0052] Among them, the RTK module 120 and the RTK antenna 121 are respectively installed on the opposite surfaces of the cover body 11, the RTK module 120 and the RTK antenna 121 are electrically connected, and the RTK module 120 is electrically connected to the control board 14 and the processor 15 respectively. The RTK module 120 is arranged in the installation cavity, and the RTK antenna 121 is arranged outside the installation cavity.

[0053] The main function of the RTK antenna 121 is to receive the carrier phase signals emitted by the GPS satellites, and the RTK module 120 is used to receive the carrier phase signals transmitted by the RTK antenna 121, and use the real-time differential solution technology to calculate the position coordinates with high precision, measure and record the position information of the anchor bolts and the base, for example, the specific position of the anchor bolts and the base relative to the width direction of the railway and the kilometer marker position of the anchor bolts along the length direction of the railway, that is, the accurate location of the anchor bolts and the base along the railway line.

[0054] The RTK module 120 can be selected as BG-350 or BG-358, and the RTK antenna 121 can be selected as BT-208. The specific structure of the RTK module 120 and the RTK antenna 121 is the prior art, which will not be described in detail here.

[0055] The information acquisition mechanism 13 is arranged in the mounting cavity, and the acquisition port of the information acquisition mechanism 13 is arranged towards the window 101 for acquiring the three-dimensional data and image information of the target object outside through the window 101, and generating three-dimensional point cloud data.

[0056] Further, the information acquisition mechanism 13 includes a three-dimensional scanning camera 130 and a visible light camera 131.

[0057] The visible light camera 131 and the three-dimensional scanning camera 130 are arranged in the mounting cavity, and the shooting ends of the visible light camera 131 and the three-dimensional scanning camera 130 are both arranged towards the window 101. Optionally, the visible light camera 131 and the three-dimensional scanning camera 130 can be fixed in the mounting cavity through a first mounting bracket, and the first mounting bracket can be fixed to the inner wall of the cover body 11 or the shell 10 through a threaded fastener, for example, as shown in Figure 3 and Figure 4 The first mounting bracket is connected with the cover body 11.

[0058] It should be noted that the number of windows 101 is at least one, which can be a single window 101 or multiple windows 101. In the case of a single window 101, the aperture needs to be large enough, at least larger than the sum of the apertures of the shooting ends of the visible light camera 131 and the three-dimensional scanning camera 130, to ensure that the shooting ends of the two cameras can pass through the window 101 without obstruction to capture the images of the anchor bolts and the base outside. If multiple windows 101 are provided, the layout can be referred to as shown in Figure 2 At this time, the shooting ends of the visible light camera 131 and the three-dimensional scanning camera 130 should be able to align with the respective windows 101 respectively, so as to ensure that both cameras can effectively shoot the anchor bolts and the base outside through the corresponding windows 101.

[0059] The visible light camera 131 and the three-dimensional scanning camera 130 are electrically connected with the control board 14 and the processor 15 respectively.

[0060] The three-dimensional scanning camera 130 is used for three-dimensional data scanning of the anchor bolt and the base, and generates three-dimensional point cloud data, which is sent to the processor 15, thereby providing accurate shape and size information of the anchor bolt and the base, and providing a reliable basis for subsequent analysis, processing and modeling.

[0061] The visible light camera 131 is used for shooting actual image information of the object, which is convenient for customers or workers to view, and is also convenient for comparison with the image after modeling, so as to ensure the accuracy of the measurement after modeling.

[0062] The control board 14 is arranged in the mounting cavity, and the control board 14 is electrically connected with the RTK assembly 12 and the information acquisition mechanism 13, wherein the control board 14 is used for controlling and coordinating the work between the RTK assembly 12 and the information acquisition mechanism 13.

[0063] The processor 15 is arranged in the mounting cavity, and the processor 15 is electrically connected with the RTK assembly 12, the information acquisition mechanism 13 and the control board 14, and is used for processing three-dimensional data, image information and position coordinates.

[0064] It should be noted that the processor 15 can adopt a microprocessor (MPU, Microprocessor Unit), a digital signal processor (Digital Signal Process), a system on chip (System on Chips) or other existing processors, which is used for processing information collected by the information acquisition mechanism 13. The information includes three-dimensional data collected by the three-dimensional scanning camera 130 and three-dimensional point cloud data generated by the three-dimensional scanning camera 130, and image information shot by the visible light camera 131. Meanwhile, the processor 15 can also upload the acquired information to a processing end through a wireless (WiFi) network.

[0065] Optionally, a USB interface can also be arranged on the shell 10, and the USB interface is connected with the processor 15. When the processing end is an electronic device such as a tablet computer or a notebook computer, which is convenient to carry, a user can directly connect the processing end through the USB interface, so as to send information to the processing end and accelerate the speed of information sending. This design not only significantly improves the speed of information sending, but also provides a convenient interface required for developers for debugging and development, thereby greatly improving work efficiency.

[0066] The control button 16 is arranged on the cover 11 and is electrically connected with the control board 14 to control the information acquisition mechanism 13 through the control board 14, that is, the user can input instructions to control the working of the handheld three-dimensional detection device. The instructions are sent to the control board 14 by the control button 16, and then are analyzed and executed by the control board 14, so as to realize the accurate control of the RTK component 12 and the information acquisition mechanism 13.

[0067] Specifically, in the actual process of measuring the overhead contact system foundation bolt, first, the user places the handheld three-dimensional detection device above the foundation bolt base, and adjusts it to a suitable position. Then, the user controls the information acquisition mechanism 13 through the control button 16, and the information acquisition mechanism 13 can acquire the three-dimensional data and image information of the foundation bolt and the base, generate three-dimensional point cloud data, and send the data to the processor 15 for processing. Meanwhile, the RTK component 12 also sends the positioning data of the position coordinates of the foundation bolt and the base to the processor 15 for processing. These data can be processed in the processor 15 in real time, or can be transmitted to the processing end (such as a tablet computer) in real time through a WIFI wireless network for further operation.

[0068] For example, taking the processing end as an example, in the processing end, the three-dimensional processing software of the processing end can comprehensively analyze and process the three-dimensional data. The processing end can pre-process the received three-dimensional point cloud data, remove the noise and isolated points of the three-dimensional point cloud data, and identify the contour and position of the bolt from the three-dimensional model through the automatic identification function or manual selection tool of the three-dimensional processing software. According to the identified bolt contour, the three-dimensional processing software is used to model the bolt, including the bolt head, the rod part and the threaded part. In the three-dimensional model, a suitable reference surface, such as the plane of the bolt mounting surface, is selected as the starting point of the exposed length calculation. The distance from the reference surface to the end of the bolt rod is measured by using the measurement tool of the three-dimensional software, that is, the exposed length of the bolt and the bolt spacing and other data. This calculation process mainly depends on the accurate measurement and comparison of specific parts in the three-dimensional point cloud data of the bolt. In addition, the three-dimensional processing software of the processing end can accurately calculate the spacing between the bolts according to the relative position and distance information in the three-dimensional point cloud data.

[0069] Meanwhile, the processing end can jointly solve the world coordinate system position of the center position of the cement foundation bolt array according to the obtained three-dimensional point cloud data and positioning data of the measured object. The geometric data and coordinate related data of the cement base and the bolt are stored in the local computer in the form of a file, which is convenient for subsequent searching. In addition, the processing end can analyze and judge the related data while processing and displaying the data, and alarm for the case exceeding the threshold range.

[0070] Therefore, the hand-held three-dimensional detection device can accurately and efficiently measure a series of key data such as bolt exposed length and bolt spacing, and provides strong support for the measurement of catenary foundation bolts, and the measurement process is simple, convenient and fast, significantly reduces the demand for manual recording, and greatly improves the measurement efficiency of the bolts.

[0071] Further, in an embodiment of the present application, as shown in Figure 1 The control button 16 further comprises a first button 160 and a second button 161.

[0072] The first button 160 and the second button 161 are arranged on the cover body 11 respectively, and the first button 160 and the second button 161 are electrically connected with the control board 14 respectively. The first button 160 is used to control the visible light camera 131 to enter a preview mode through the control board 14, and the second button 161 is used to control the three-dimensional scanning camera 130 and the visible light camera 131 to take pictures through the control board 14.

[0073] Specifically, when the first button 160 is operated, the control board 14 will receive the corresponding signal, and accordingly start the preview mode of the visible light camera 131. In this mode, the processor 15 can capture the picture displayed under the lens of the visible light camera 131 in real time, and transmit these real-time pictures to the processing end (for example, a tablet computer) through a wireless network. In this way, the user can clearly view the current shooting position of the hand-held three-dimensional detection device, so as to make instant position adjustment according to the actual situation, so that the hand-held three-dimensional detection device and the photographed base are in a suitable position, so as to facilitate subsequent data collection work, and the suitable position can be that the hand-held three-dimensional detection device is in the center position of the base.

[0074] When the second button 161 is pressed, the three-dimensional scanning camera 130 and the visible light camera 131 can be controlled to take pictures through the control board 14, and the three-dimensional and image data of the base and the foundation bolt can be collected comprehensively, so as to provide detailed and accurate information basis for subsequent analysis, processing and modeling work.

[0075] In an embodiment of the present application, as shown in Figure 3 and Figure 4 The hand-held three-dimensional detection device further comprises an infrared laser light compensator 17 and an LED light compensator 18.

[0076] The infrared laser light compensator 17 and the LED light compensation lamp 18 are arranged in the mounting cavity respectively, the probe heads of the infrared laser light compensator 17 and the LED light compensation lamp 18 are all directed to the window 101, the infrared laser light compensator 17 and the LED light compensation lamp 18 are electrically connected with the control panel 14 respectively, the second button 161 is further used for triggering the infrared laser light compensator 17 and the LED light compensation lamp 18 to start when the three-dimensional scanning camera 130 and the visible light camera 131 are started to shoot, wherein, optionally, the LED light compensation lamp 18 can be fixed in the mounting cavity through the first mounting bracket, the infrared laser light compensator 17 can be fixed in the mounting cavity through the first mounting bracket, and the first mounting bracket and the second mounting bracket can be fixed with the inner wall of the cover body 11 or the shell 10 through threaded fasteners, for example, refer to Figure 3 and Figure 4 The first mounting bracket and the second mounting bracket are connected with the cover body 11.

[0077] The infrared laser light compensator 17 can compensate the light source when the three-dimensional scanning camera 130 is shooting, improve the shooting accuracy, the laser light source has high directionality and consistency, can provide stable light irradiation in the scanning process, and the consistency helps to reduce the measurement error caused by the change of ambient light or the difference of object surface reflection, and improve the accuracy of the scanning result; and the laser light source can inhibit the interference of external light to a certain extent, and reduce the error caused by the change of ambient light in the scanning process. For example, in an outdoor or large light change environment, the laser light compensation source can help to maintain the stability and consistency of the scanning.

[0078] In addition, the LED light compensation lamp 18 is used for supplementing the light source and enhancing the ambient light when the visible light camera 131 is shooting, thereby improving the shooting effect of the visible light camera 131.

[0079] Specifically, when the three-dimensional scanning camera 130 and the visible light camera 131 are started to shoot through the second button 161, the infrared laser light compensator 17 and the LED light compensation lamp 18 can be triggered to start through the control panel 14, clear and accurate light is provided for the scanning area, and the collection quality of three-dimensional data is ensured. The LED light compensation lamp 18 will light up when the visible light camera 131 is shooting, and soft and uniform light is provided for the shooting area, so that the shot image is clearer and brighter.

[0080] As a possible case, refer to Figure 3 As shown in FIG. 6, in order to reduce the space occupied by the infrared laser light compensator 17 and make the whole structure compact, a clamping block and a reflecting sheet are arranged on the infrared laser light compensator 17, the reflecting sheet is detachably connected with the clamping block, and the light source is reflected out through the reflecting sheet.

[0081] In an embodiment of the present application, as shown inFigure 1 and Figure 5 As shown in the figure, the handheld three-dimensional detection device further comprises indicator lights 19, which include a power indicator light 190, a system indicator light 191 and a trigger indicator light 192.

[0082] The power indicator light 190, the system indicator light 191 and the trigger indicator light 192 are arranged on the cover body 11 respectively, and are electrically connected with the control panel 14 respectively, so that their on-off states are controlled by the control panel 14.

[0083] The main function of the power indicator light 190 is to show whether the handheld three-dimensional detection device is powered on. When the power is turned on, the power indicator light 190 will light up, reminding the user that the device has been powered on and can work normally. This design is very intuitive, and the user can see at a glance whether the device is in the power-on state.

[0084] Secondly, the system indicator light 191 is used to show whether the components (such as the three-dimensional scanning camera 130, the visible light camera 131, the infrared laser light compensator 17, the LED light compensator 18, etc.) connected with the control panel 14 are working normally. When all these components are working normally, the system indicator light 191 will present a slow flickering state, indicating that the entire handheld three-dimensional detection device is in a stable working state. If a component (for example, the infrared laser light compensator 17) in the handheld three-dimensional detection device is abnormal, the flickering state of the system indicator light 191 may change, so that the user can find and handle it in time.

[0085] Finally, the trigger indicator light 192 is specially used to remind the user whether the three-dimensional scanning camera 130 is in the working state. When the three-dimensional scanning camera 130 starts scanning, the trigger indicator light 192 will light up, indicating that the camera is working. Thus, it helps the user to understand the working state of the camera in real time, so as to avoid missing any important information during the scanning process.

[0086] Specifically, when the handheld three-dimensional detection device is powered on, the control panel 14 will immediately detect the access of the power supply and trigger the power indicator light 190 to light up. At the same time, the control panel 14 will also constantly monitor the working state of the components connected with the control panel 14, and once it is detected that all the components are working normally, the system indicator light 191 will start to flicker slowly. When the user presses the shooting button (such as the second button 161) to start the three-dimensional scanning camera 130 to scan, the control panel 14 will receive the shooting instruction and immediately trigger the trigger indicator light 192 to light up, indicating that the three-dimensional scanning camera 130 has started to work.

[0087] In an embodiment of the present application, as Figure 3As shown, the handheld three-dimensional detection device can further include a posture sensor 20 arranged in the mounting cavity, and the posture sensor 20 is electrically connected with the processor 15, and is used for acquiring posture data of the shell 10 in a shooting process, so as to help the handheld three-dimensional detection device to determine its own position in a complex environment to ensure the accuracy and integrity of data in the scanning process; meanwhile, in the 3D scanning, data is usually collected from multiple positions, and the posture information provided by the posture sensor 20 can help to align the scanning data of different positions, so that the final 3D model can seamlessly fuse the data of multiple positions; on the other hand, during the scanning process, especially for the handheld three-dimensional detection device, irregular hand movements are inevitable, and these movements can introduce errors, and the posture sensor 20 can detect these movements and compensate in the processor 15 in the data processing, so as to reduce the influence of the motion error on the scanning result.

[0088] Optionally, the posture sensor 20 can be fixed on a side surface of the cover body 11 near the mounting cavity, or can be fixed on the inner wall of the mounting cavity, which can be selected according to the actual situation, and is not limited here.

[0089] In an embodiment of the utility model, as shown in the figure, Figure 1 As shown, the handheld three-dimensional detection device further includes a display screen 21 embedded on the cover body 11, and the display screen 21 is electrically connected with the processor 15 and the control panel 14, and is used for providing a human-computer interaction interface, so that the user can view the preview picture on the display screen 21 fed back by the processor 15 to the display screen 21 through the display screen 21, the real-time preview image of the pedestal and the anchor bolt currently being scanned, and simultaneously after shooting is completed, the three-dimensional pseudo-color map and the surface map of the photographed object are generated and displayed on the display screen 21 for viewing, so as to provide real-time information and operation feedback for the operator, thereby helping the user to more effectively perform the scanning operation and monitor the scanning process.

[0090] Meanwhile, during the process of adjusting the inclination of the handheld three-dimensional detection device, a sighting frame appears on the display screen 21, and when the sighting frame is completely coincident with the pedestal, it indicates that the measuring device and the pedestal are in a parallel state, and at this time, scanning can be performed.

[0091] In an embodiment of the utility model, as shown in the figure, Figure 1 As shown, the two sides of the shell 10 are respectively provided with first protruding parts 220, and the two sides of the cover body 11 are respectively provided with second protruding parts 221, and when the second protruding parts 221 are overlapped on the first protruding parts 220, a handle part 22 is formed, wherein it can be understood that by arranging the handle part 22, a holding point is provided for the user, so that the user can hold the handheld three-dimensional detection device more stably during operation, and the measurement error caused by hand shaking is reduced, thereby facilitating carrying and handheld measurement.

[0092] In an embodiment of the utility model, as shown in Figure 1 The hand-held three-dimensional detection device further comprises a level 23, and the level 23 is arranged on the cover body 11.

[0093] The level 23 arranged in the hand-held three-dimensional detection device is designed to help the operator accurately determine the horizontal state of the device during measurement. When the three-dimensional scanning camera 130 is used for scanning operation, the three-dimensional scanning camera 130 and the base are ensured to be parallel, so as to ensure the accuracy of the scanning data. However, in actual operation, due to the limitation of manual operation, it is difficult to make the three-dimensional scanning camera 130 completely parallel to the base. At this time, the operator can intuitively understand the inclination degree of the shell 10 by observing the position of the water bubble in the level 23. This function provides real-time inclination feedback for the operator, so that they can quickly and accurately adjust the inclination state of the measurement device, which greatly facilitates the operator.

[0094] It should be noted that the electrical connection described in the above text can be achieved by wire connection, and the utility model is mainly used for protecting the structure device, so the control mode and circuit connection of the utility model will not be explained in detail.

[0095] In summary, the hand-held three-dimensional detection device of the utility model embodiment can accurately and efficiently measure whether the exposed length of the bolt and the bolt spacing meet the requirements, and simultaneously record the position standard, so that the measurement process is simple, convenient and fast, the demand for manual recording is significantly reduced, and the measurement efficiency of the bolt is greatly improved.
