[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] like Figure 1 and Figure 2 As shown, the handheld positioning terminal for 3D modeling provided by this utility model includes a housing 1, with a display screen 2 on the first side of the housing 1. A camera module 3 and a laser scanner 4 are located on the second side of the housing, wherein the camera module 3 is communicatively connected to the display screen 2. Thus, the camera module 3 can transmit images of the target object captured by the camera to the display screen 2. The laser scanner 4 is used to emit a laser beam towards the target object, and by measuring the flight time and phase difference through the emission and reflection of the laser beam, it calculates the three-dimensional coordinates of the target object, obtaining the point cloud data of the target object.

[0032] An image processing module is installed inside the housing 1. This module communicates with the laser scanner 4 to construct a 3D model of the target object. The image processing module also communicates with the display screen 2 to send the 3D model of the target object to the display screen 2. A positioning device is also installed inside the housing 1. This positioning device is used to acquire the geographical location information of the handheld positioning terminal. The positioning device communicates with the image processing module, which, based on the geographical location information of the handheld positioning terminal and the 3D model of the target object, obtains the geographical location information of the target object.

[0033] In this way, during the surveying process, users can view the image of the target object in real time on the display screen 2, and can also intuitively understand the three-dimensional structure of the target object through the 3D model processed by the image processing module. In addition, due to the addition of the positioning device, the handheld positioning terminal can also combine the 3D model of the target object with its actual geographical location to obtain the geographical location information of the target object, such as latitude, longitude and angle information, providing richer data support for subsequent 3D modeling applications.

[0034] In this embodiment of the invention, the first surface and the second surface are opposite to each other; that is, the first surface is the front of the shell 1, and the second surface is the back of the shell 1. Figure 2 As shown, the camera module 3 and laser scanner 4 are located on the upper part of the second surface, which is provided with an anti-slip pad 7. During the surveying process, the user holds the handheld positioning terminal perpendicular to the horizontal plane so that the camera module 3 and laser scanner 4 are facing the surface of the target object, thereby realizing 3D modeling and positioning of the target object.

[0035] In this embodiment of the invention, a keyboard 5 is also provided on the first side of the housing 1, and the keyboard 5 is located below the display screen. The keyboard 5 includes, from top to bottom, a function key area, an arrow key area, a numeric key area, and an alphabetic key area. In this way, the user can conveniently input various commands and data through the keyboard 5, such as adjusting the working parameters of the camera module 3 and the laser scanner 4, selecting the surveying mode, and inputting the name and attributes of the target object, etc.

[0036] For example, the function key area can be configured with commonly used shortcut functions, such as start surveying, stop surveying, save data, and enable positioning, improving user efficiency. The arrow keys are used to move the cursor up, down, left, and right in the menu or interface to select the desired option. The numeric and letter keys can be used to input specific numerical and text information to meet various surveying needs.

[0037] In this embodiment, the housing 1 is provided with a handheld part 6, which includes a groove. The handheld part 6 is disposed on both sides of the keyboard 5, and the groove of the handheld part 6 is provided with anti-slip texture. In this way, the user can hold the handheld positioning terminal more comfortably. The groove design can also increase the friction between the hand and the handheld part 6, preventing the handheld positioning terminal from slipping due to sweaty hands or improper operation during the surveying process, thereby improving the safety and accuracy of the surveying. In addition, the back of the housing 1 is also provided with an anti-slip pad 7 to further enhance the stability of the grip.

[0038] In this embodiment of the invention, the positioning device includes an RTK antenna, which is detachably connected to the top of the housing. The RTK antenna possesses high-precision positioning capabilities, achieving centimeter-level accuracy. By detachably connecting the RTK antenna to the top of the housing, users can easily install and remove it during surveying. Furthermore, different models of RTK antennas can be replaced according to actual needs to adapt to different surveying environments and accuracy requirements. The detachable design also facilitates the maintenance and upkeep of the RTK antenna, extending its service life.

[0039] In this embodiment of the invention, a battery is housed within the casing 1, enabling the handheld positioning terminal to operate for extended periods without external power, thus improving ease of use and flexibility. The battery is a high-performance lithium battery, characterized by its large capacity and long lifespan, meeting the needs of prolonged surveying work. Simultaneously, a battery power indicator module is also included within the casing 1, displaying the remaining battery power in real time and reminding the user to charge it promptly, preventing work progress from being affected by insufficient power during surveying. Furthermore, the battery design prioritizes easy replacement; users can easily open the casing to quickly replace the battery, ensuring the continuous operation of the handheld positioning terminal.

[0040] Furthermore, such as Figure 3 As shown, the side of the housing 1 has a charging port and a dust plug 8, which is inserted into the charging port. This effectively prevents dust and debris from entering the charging port in outdoor surveying environments, ensuring its cleanliness and good contact, and avoiding charging problems or interface damage caused by dust. At the same time, the design of the dust plug 8 allows for quick insertion and removal by the user, ensuring dust protection without affecting the convenience of charging operations. Furthermore, the charging port's reasonable location allows users to charge without disassembling the housing, further improving ease of use.

[0041] In this embodiment of the invention, a working indicator light 9 is provided on the first side of the housing 1, and the working indicator light 9 is located above the display screen. The user can intuitively determine the working status of the handheld positioning terminal according to the working indicator light 9.

[0042] For example, when the terminal is in operation, indicator light 9 will light up to remind the user that operations such as location or data transmission are currently in progress. This design helps users better understand the terminal's operating status, thereby enabling them to perform 3D modeling work more effectively.

[0043] In another embodiment of this utility model, the second surface of the housing 1 is adjacent to the first surface, and the second surface is close to the display screen 2. That is, the first surface is the front surface of the housing 1, and the second surface is the top surface of the housing 1. Figure 4 As shown, the camera module 3 and the laser scanner 4 are located on the top of the housing 1. During the surveying process, the user can hold the handheld positioning terminal parallel to the horizontal plane to achieve 3D modeling of the target object and generate the geographical location information of the target object in combination with the positioning module.

[0044] As can be seen from the above technical solution, this utility model discloses a handheld positioning terminal for 3D modeling, including a housing; a display screen is provided on the first side of the housing, and a camera module is provided on the second side, with the camera module communicating with the display screen. A laser scanner is also provided on the second side of the housing, and an image processing module is installed inside the housing, communicating with the laser scanner to construct a 3D model of the target object. A positioning device is installed inside the housing, communicating with the image processing module to generate the geographical location information of the target object.

[0045] During use, users simply hold the terminal and scan the target object to generate a high-precision 3D model in real time. This allows for the extraction of various detailed parameters of the object, such as volume, surface area, and curvature, significantly improving the accuracy and comprehensiveness of data acquisition. Furthermore, the positioning device generates the target object's geographical location information, providing richer data support for 3D modeling. This handheld terminal is compact, lightweight, and portable, making it ideal for extended data collection in outdoor or complex environments.

[0046] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
