Description

Technical Field

[0001] The utility model relates to the field of three-dimensional point cloud data acquisition of oil and gas field stations, and in particular to an auxiliary device for SLAM scanning operations of oil and gas field stations. Background Art

[0002] SLAM technology, standing for Simultaneous Localization and Mapping, is also known as mobile scene reconstruction. This technology, whether operated manually or mounted on a vehicle, enables mobile scanning of a scene, capturing comprehensive scene data. SLAM technology boasts several key features: It is extremely portable. The equipment is generally designed to be lightweight, often weighing less than 3 kilograms, making it portable and user-friendly. It also offers fast and efficient operation. SLAM equipment allows operators to easily perform mobile operations, while the device automatically collects data about the surrounding scene, eliminating the need for tedious manual intervention and operation. Data processing is also extremely simple. SLAM equipment not only possesses powerful data collection capabilities but also excels in post-processing. It automatically stitches and integrates data, ultimately outputting complete and accurate results, eliminating the tedious and complex manual post-processing.

[0003] Because of these significant advantages, SLAM technology has now been widely used in various sectors of the national economy, becoming an indispensable tool in many fields. In particular, in the fields of cadastral surveying, historical archaeology, and topographic mapping, SLAM technology has won wide recognition and praise for its excellent performance and precise results.

[0004] In the field of oil and gas field surface construction, the tasks of site surveying and renovation are increasing. Especially in the current context of digital site construction, the demand for 3D scanning and measurement of sites continues to grow. SLAM technology, with its high precision and efficiency, has shown great potential in oil and gas field site surveying. However, while the data accuracy of SLAM equipment has met the measurement requirements of oil and gas field sites, some challenges still exist in practical application. For example, the axis alignment of local buildings may not be clear, and the recognition of building corners and equipment needs to be improved.

[0005] In order to solve these problems and further improve the scanning accuracy of key buildings and equipment in oil and gas field stations, an auxiliary device for SLAM scanning operations in oil and gas field stations is urgently needed. Utility Model Content

[0006] The purpose of the utility model is to provide an auxiliary device for SLAM scanning operations in oil and gas field stations, which can form a good cooperation with the SLAM equipment, effectively improve the scanning accuracy and recognition of specific targets, thereby ensuring the accuracy and reliability of oil and gas field station measurements to overcome the shortcomings of the existing technology such as unclear fitting of the axis of local buildings; poor recognition of the corners of buildings and equipment.

[0007] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions:

[0008] An auxiliary device for SLAM scanning operations at oil and gas field stations includes a black reflector and a white reflector. The black and white reflectors are connected diagonally to form an n×n rectangle, with a flexible joint at the junction. The n can be flexibly adjusted based on actual needs to accommodate the scanning requirements of stations of varying sizes. The flexible joint design at the junction of the black and white reflectors not only ensures a secure connection between the reflectors but also provides flexibility and adaptability for the entire device, facilitating installation on walls of varying curvatures or irregularities.

[0009] Furthermore, the black reflective sheet includes a first black reflective sheet and a second black reflective sheet, and the white reflective sheet includes a first white reflective sheet and a second white reflective sheet; the right side of the first white reflective sheet is connected to the first black reflective sheet, the bottom of the first white reflective sheet is connected to the second black reflective sheet, the bottom of the first black reflective sheet is connected to the second white reflective sheet, and the second black reflective sheet and the second white reflective sheet are connected to form a complete rectangular array; such a layout helps the SLAM device to capture environmental features more accurately during the scanning process, thereby improving positioning accuracy and map construction accuracy.

[0010] Furthermore, both the black and white reflective sheets are coated with self-adhesive adhesive on the back, allowing users to simply remove the protective layer and adhere the sheet to the wall. Simply peeling off the protective layer allows the sheet to be easily attached to walls or other flat surfaces at oil and gas field stations, eliminating the need for additional tools or steps, greatly simplifying the installation process.

[0011] Furthermore, the flexible joint is made of a flexible material and can be stretched freely to a length of 3mm-10mm, allowing the auxiliary device to easily adapt to slight undulations or unevenness of the wall surface, ensuring that the reflective sheets always remain tightly fitted to avoid light leakage or reduced reflection effect.

[0012] Furthermore, a black paint layer is provided on the surface of the black reflective sheet; the black paint can maximize the absorption of light and reduce unnecessary reflection interference.

[0013] Furthermore, a white reflective agent layer is provided on the surface of the white reflective sheet; this special material can not only effectively reflect light, but also significantly improve the reflectivity of the SLAM device, further enhancing the scanning effect.

[0014] Furthermore, the black reflective sheet has a length and width of 5 mm, and the white reflective sheet has a length and width of 5 mm, which ensures sufficient reflection area and the overall lightness and portability of the device.

[0015] Furthermore, the black reflective sheet is made of flexible plastic, and the white reflective sheet is made of flexible plastic, which not only ensures durability and wear resistance, but also gives the device a certain flexibility, facilitating flexible application in different environments.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects:

[0017] This utility model provides an auxiliary device for SLAM scanning operations at oil and gas field stations, comprising a black reflective sheet and a white reflective sheet connected diagonally. The black and white combination can produce a clear, dense four-grid point cloud. In practical applications, multiple such auxiliary devices, connected at their center points, can accurately extract edges. During on-site data collection at the station, this device makes the position information of key features such as the edges of buildings and various equipment, as well as corners, more clearly discernible, greatly improving the accuracy of coordinate measurement. The device is suitable for high-precision three-dimensional data acquisition and digital transformation in oil and gas fields.

[0018] Specifically, the use of this device enables unprecedented clarity in the point cloud data generated by SLAM operations. Detailed features, such as edges and corners, are clearly and intuitively displayed in the point cloud, facilitating the extraction and delineation of point cloud data by subsequent operators and significantly improving work efficiency and accuracy.

[0019] Specifically, the coordinates of the point cloud data are highly accurate. The basic outline scanned by the device can be clearly displayed, especially the point cloud data coordinates at the corners, which can be accurately marked.

[0020] Specifically, the use of this auxiliary device has also significantly reduced operating time. By installing the device in key corner locations, the time required for both field data collection and office data extraction has been effectively controlled, significantly improving efficiency compared to previous traditional methods.

[0023] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0024] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0025] An auxiliary device for SLAM scanning operations at oil and gas field stations. When collecting on-site data at the station, the edges and corners of buildings and equipment are more clearly visible, and the coordinate measurement accuracy is higher. It is suitable for high-precision three-dimensional data collection and digital transformation of oil and gas fields.

[0026] See Figure 1, including a black reflective sheet and a white reflective sheet; the black reflective sheet and the white reflective sheet are connected diagonally to form an n×n rectangle, the length and width of the black reflective sheet are both 5mm, and the length and width of the white reflective sheet are both 5mm, which not only ensures that the reflective sheet has sufficient reflective area to effectively reflect light and provide sufficient scanning information for the SLAM equipment, but also ensures the overall lightness and easy portability of the device. In actual operations, workers can easily carry a large number of auxiliary devices to various corners of the oil and gas field station for installation without causing inconvenience due to the device being too heavy or too large. The bottom of the black reflective sheet is flexible plastic, and the surface is a metal hard sheet with a black paint layer. The bottom of the white reflective sheet is flexible plastic, and the surface is a metal hard sheet with a white reflective agent layer. The connection between the black reflective sheet and the white reflective sheet is a flexible connection seam 1. The flexible connection seam 1 is made of flexible material and can be stretched freely. The stretching length is 3mm-10mm; for easy installation, self-adhesive glue 4 is provided on the back of the black reflective sheet and the white reflective sheet. When in use, the user only needs to simply tear off the protective layer to easily stick the reflective sheet on the wall or other flat surface of the oil and gas field station without the need for additional fixing tools or steps, which greatly simplifies the installation process.

[0027] The value of n here is not fixed but can be flexibly adjusted based on specific operational needs. This variability allows the auxiliary device to perfectly adapt to the scanning needs of sites of varying sizes, delivering exceptional performance in both small, simple sites and large, complex oil and gas field complexes. The connection between the black and white reflective sheets is designed as a flexible joint 1. This ensures a secure connection between the reflective sheets while allowing the auxiliary device to easily fit onto walls with varying curvatures or irregularly shaped surfaces found in oil and gas field sites.

[0028] The black reflective sheet is coated with black paint because black paint has excellent light-absorbing properties, maximizing light absorption and minimizing unwanted reflection interference. In SLAM scanning operations, reducing reflection interference is crucial for improving the accuracy and clarity of scanned data. The white reflective sheet, on the other hand, is coated with a white reflective agent that not only efficiently reflects light but also significantly increases the reflectivity of the SLAM device. During the scanning process, this highly reflective white reflective sheet works seamlessly with the SLAM device, further enhancing the scanning effect and resulting in more accurate and detailed scanned data.

[0029] In practice, the black reflective sheet is subdivided into a first black reflective sheet 2 and a second black reflective sheet 5, while the white reflective sheet is correspondingly divided into a first white reflective sheet 3 and a second white reflective sheet 6. This segmented design allows the reflective sheets to be arranged in a specific "checkerboard" pattern: the first white reflective sheet 3 is adjacent to the first black reflective sheet 2 on the right, and connected to the second black reflective sheet 5 below it; correspondingly, the first black reflective sheet 2 is connected to the second white reflective sheet 6 below it; finally, the second black reflective sheet 5 and the second white reflective sheet 6 are connected at the other end of the array, forming a complete rectangular array. This layout helps the SLAM device more accurately capture environmental features during scanning, improving positioning accuracy and map construction accuracy. During field implementation, the device is first opened and, using the four self-adhesive strips on the back, attached to objects on both sides along the corners of a building. The SLAM device is then used for on-site scanning.

In this specification, schematic representations of the above terms do not necessarily refer to the same embodiment or example.
