[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0019] Reference Figures 1-4 This is an embodiment of the present invention, which provides a multi-camera fusion visual positioning and measurement device, including, The system includes a support base 101, a column 102 fixedly connected to the inner wall of the support base 101, a fixing assembly 103 bolted to the side wall of the column 102, a support plate 104 fixedly connected to the side wall of the fixing assembly 103, a housing 105 fixedly connected to the surface of the support plate 104, a camera assembly 106 fixedly connected to the side wall of the support plate 104, a light source assembly 107 fixedly connected to the bottom side wall of the support plate 104, and a laser assembly 108 fixedly connected to the bottom of the light source assembly 107.

[0020] Specifically, the camera assembly 106 includes a mounting groove 106a formed on the side wall of the support plate 104, a connecting plate 106b fixedly connected to the inner wall of the mounting groove 106a, a camera 106c fixedly connected to the side wall of the connecting plate 106b, and a lens 106d fixedly connected to the bottom of the camera 106c.

[0021] In this process, multiple camera components 106 are activated simultaneously, with the lens 106d aimed at the target area. Under the stable illumination provided by the ring light source 107d, image data including the laser reference line and the characteristics of the target area are acquired. The orientation of the lens 106d can be preset according to the measurement requirements to achieve image acquisition of the target area. At the same time, multiple camera components 106 can be set to achieve all-round visual information capture of the target from different angles, providing a rich data foundation for subsequent fusion positioning.

[0022] Furthermore, the fixing component 103 includes a fixing block 103a bolted to the side wall of the column 102, and a bolt hole 103b opened in the side wall of the fixing block 103a. The fixing component 103 also includes a fixing bolt 103c threaded to the inner wall of the bolt hole 103b, and a fixing plate 103d fixedly connected to the side wall of the fixing block 103a.

[0023] The height and angle of the support plate 104 are adjusted by fixing the component 103. This is achieved by loosening the fixing bolt 103c and moving the fixing block 103a up and down along the column 102 to a suitable height, thereby adjusting the angle of the fixing plate 103d so that the support plate 104 is in the optimal measurement posture. Then, the fixing bolt 103c is tightened to complete the fixing.

[0024] Preferably, the light source assembly 107 includes a light source mounting plate 107a fixedly connected to the side wall of the support plate 104, and a light source mirror 107b disposed on the inner wall of the light source mounting plate 107a. The light source assembly 107 also includes a light source controller 107c movably connected to the side wall of the light source mirror 107b, and an annular light source 107d disposed at the bottom end of the light source mounting plate 107a.

[0025] Specifically, by activating the light source controller 107c, the brightness and flicker parameters of the ring light source 107d are adjusted according to the ambient light conditions, thereby enabling the ring light source 107d to provide uniform illumination to the measurement target area. The ring light source 107d is set at the bottom of the light source mounting plate 107a, and its ring structure can achieve uniform illumination of the measurement target, avoid shadows, and ensure that the image captured by the camera has clear details and moderate contrast.

[0026] It should be noted that the laser assembly 108 includes a laser fixture 108a fixedly connected to the surface of the light source mounting plate 107a, and a linear laser 108b disposed on the inner wall of the laser fixture 108a. The laser assembly 108 also includes a reflector seat 108c fixedly connected to the bottom end of the laser fixture 108a, and a reflector 108d disposed on the surface of the reflector seat 108c.

[0027] Specifically, the linear laser 108b is activated, and the laser beam is reflected to the key position of the measurement target by adjusting the angle of the reflector 108d to form a high-precision laser reference line. By adjusting the angle of the reflector 108d, the laser beam emitted by the linear laser 108b can be reflected to the measurement target area to form a clear laser reference line, providing a position reference for image acquisition by the camera assembly 106.

[0028] In use, firstly, based on the size and position of the target being measured, adjust the height and angle of the support plate 104 using the fixing component 103 by loosening the fixing bolts 103c. Simultaneously, move the fixing block 103a up and down along the column 102 to a suitable height, thereby adjusting the angle of the fixing plate 103d to place the support plate 104 in the optimal measurement posture. Then, tighten the fixing bolts 103c to complete the fixation. Activate the light source controller 107c and adjust the brightness and flicker parameters of the ring light source 107d according to the ambient light conditions. This allows the ring light source 107d to provide uniform illumination to the target area. The ring light source 107d, positioned at the bottom of the light source mounting plate 107a, provides uniform illumination of the target, avoiding shadows and ensuring clear image details and moderate contrast in the camera-acquired image. Then, activate the linear laser 108b. By adjusting the angle of reflector 108d, the laser beam is reflected to the key position of the measurement target, forming a high-precision laser reference line. By adjusting the angle of reflector 108d, the laser beam emitted by linear laser 108b can be reflected to the measurement target area, forming a clear laser reference line, providing a positional reference for image acquisition by camera assembly 106. By simultaneously activating multiple camera assemblies 106 and aligning lens 106d with the measurement target area, image data containing the laser reference line and measurement target features is acquired under stable illumination provided by ring light source 107d. The orientation of lens 106d can be preset according to measurement requirements to achieve image acquisition of the target area. Simultaneously setting multiple camera assemblies 106 enables omnidirectional visual information capture of the measurement target from different angles, providing a rich data foundation for subsequent fusion positioning.

[0029] In summary, the installation of the fixing component 103 ensures the stable mounting and flexible adjustment of the camera component 106, the light source component 107, and the laser component 108. The cooperation between the fixing block 103a and the column 102 ensures the stability of the overall structure. The cooperation between the bolt hole 103b and the fixing bolt 103c allows the position of the fixing block 103a on the column 102 to be adjusted. The camera component 106 enables multi-angle, high-precision image acquisition of the target object. The light source component 107 provides uniform illumination and clear imaging of the target object. The light source controller 107c... The brightness and angle of the light source can be flexibly adjusted to adapt to the needs of different measurement scenarios. The ring light source 107d provides an all-around illumination effect, ensuring that there are no shadows on the surface of the target object. Through the setting of the laser component 108, the laser emitted by the linear laser 108b is reflected by the reflector 108d to form a laser line of a specific shape or direction, providing a precise baseline or reference line for visual positioning measurement, which helps to improve the accuracy of the measurement. This multi-component collaborative working method enables the visual positioning measurement device to adapt to measurement tasks in a variety of complex environments, and has wider applicability and stronger practicality.
