Description
Technical Field
[0001] The utility model relates to the technical field of three-dimensional acquisition, in particular to a matrix camera for real-scene three-dimensional acquisition. Background Art
[0002] In the current field of real-world 3D data collection, multiple cameras are deployed in front of the target area for data collection. Traditionally, three cameras are set up on the same horizontal line, and the camera positions are repeatedly moved and recalibrated to maximize coverage of the scene and minimize acquisition defects. However, this approach has many problems and drawbacks:
[0003] The operation is cumbersome and inefficient: Since the camera needs to be moved and calibrated multiple times, the entire acquisition process is time-consuming and complicated, which greatly reduces work efficiency.
[0004] Limited viewing angle and distortion issues: A single camera has a limited viewing angle, making it difficult to fully cover the target area. Furthermore, lens distortion can easily lead to defects in the collected 3D data.
[0005] Uneven image quality: The image quality at the edges of the camera lens may be poor, affecting the authenticity and accuracy of the overall data.
[0006] Difficulty in moving and recalibrating equipment: When the area to be inspected exceeds the widest range of the lens, it is necessary to change the position and height of the fixed bracket or adjust the pitch angle of the camera, which not only increases the difficulty of operation but may also introduce new errors.
[0007] Therefore, those skilled in the art have proposed a matrix camera for real-scene three-dimensional acquisition to solve the problems raised in the background art. Utility Model Content
[0008] To address the aforementioned technical issues, this utility model provides a matrix camera for real-world 3D capture. Through the coordinated operation of multiple devices and a precise matrix arrangement, it aims to achieve more comprehensive, accurate, and efficient 3D capture of target areas. This matrix camera not only eliminates the issues of frequent device movement and recalibration, but also significantly improves acquisition efficiency. It also overcomes the limited viewing angles, distortion, and uneven image quality associated with traditional cameras, providing a solid foundation for subsequent real-world modeling.
[0009] A matrix camera for real-scene three-dimensional acquisition includes a fixed bracket, a spirit level mounted on the top of the fixed bracket, an X-axis adjustment rod mounted on the top of the spirit level, a first locking member provided on the outer side wall of the X-axis adjustment rod, a Z-axis adjustment rod rotatably connected to the outer side wall of the X-axis adjustment rod, a second locking member mounted on the outer side wall of the Z-axis adjustment rod, a Y-axis adjustment rod rotatably connected to the outer side wall of the Z-axis adjustment rod, three shooting cameras mounted on the outer side wall of the Y-axis adjustment rod, and a third locking member mounted on the outer side end of the middle portion of the shooting cameras.
[0010] Preferably, the second locking member is installed between the X-axis adjustment rod and the Z-axis adjustment rod to adjust the relationship between the X-axis adjustment rod and the Z-axis adjustment rod, and the first locking member is installed between the level and the X-axis adjustment rod to adjust the relationship between the level and the X-axis adjustment rod.
[0011] Preferably, the third locking member is installed between the Y-axis adjustment rod and the Z-axis adjustment rod, and is used to adjust the relationship between the Y-axis adjustment rod and the Z-axis adjustment rod.
[0012] Preferably, the three cameras are arranged in sequence outside the Y-axis adjustment rod, the upper camera looks up to shoot, the middle camera looks straight to shoot, and the lower camera looks down to shoot, and the viewing direction is at a 45-degree angle or vertical to the wall.
[0013] Preferably, the fixed bracket can be replaced with an unmanned vehicle, which can be controlled to move using a remote control to detect different surfaces without the need for manual handling of the fixed bracket.
[0014] Preferably, the three photos taken by the three cameras in the same direction and position are later fused and optimized into one photo, and the optimized photos taken in different directions and positions are used to generate the real-scene three-dimensional model.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. Significantly improve acquisition efficiency: By arranging multiple cameras in a matrix and controlling the terminals, the matrix camera of the utility model can simultaneously shoot from multiple angles and positions, which greatly shortens the acquisition time and improves work efficiency.
[0017] 2. Reduce human error: Traditional methods require multiple camera movements and calibrations, which can easily introduce human error. However, the matrix camera of this utility model reduces human intervention and lowers the error rate through its precise mechanical structure and automated control.
[0018] 3. Solve the problems of limited viewing angle and distortion: By combining multiple cameras in a matrix arrangement, the matrix camera of this utility model can fully cover the target area, eliminating the limited viewing angle of a single camera. At the same time, by optimizing camera settings and post-processing, lens distortion is effectively reduced and data accuracy is improved.
[0019] 4. Improved image quality uniformity: Traditional methods can suffer from poor image quality around the edges of camera lenses, impacting the authenticity and accuracy of the overall data. However, the matrix camera of this utility model optimizes camera layout and shooting angles to achieve more uniform image quality across the entire acquisition area, improving overall data quality.
[0020] 5. Enhanced flexibility and adaptability: The matrix camera of this utility model not only supports fixed bracket support, but can also be replaced by an unmanned vehicle as needed to achieve remote control and automatic movement, further improving the flexibility and adaptability of acquisition.

[0026] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0027] As attached Figure 1 To the attached Figure 4 As shown:
[0028] Embodiment 1: The present invention provides a matrix camera for real-scene three-dimensional acquisition, comprising a fixed bracket 1, a level 2 being mounted on the top of the fixed bracket 1, an X-axis adjustment rod 3 being mounted on the top of the level 2, a first locking member 4 being provided on the outer side wall of the X-axis adjustment rod 3, a Z-axis adjustment rod 5 being rotatably connected to the outer side wall of the Z-axis adjustment rod 5, a second locking member 6 being mounted on the outer side wall of the Z-axis adjustment rod 5, a Y-axis adjustment rod 7 being rotatably connected to the outer side wall of the Y-axis adjustment rod 7, Three shooting cameras 9, a third locking member 8 is installed at the outer end of the middle part of the shooting camera 9, the second locking member 6 is installed between the X-axis adjustment rod 3 and the Z-axis adjustment rod 5, and is used to adjust the relationship between the X-axis adjustment rod 3 and the Z-axis adjustment rod 5, the first locking member 4 is installed between the level 2 and the X-axis adjustment rod 3, and is used to adjust the relationship between the level 2 and the X-axis adjustment rod 3, and the third locking member 8 is installed between the Y-axis adjustment rod 7 and the Z-axis adjustment rod 5, and is used to adjust the relationship between the Y-axis adjustment rod 7 and the Z-axis adjustment rod 5.
[0029] Specifically, compared to traditional methods for capturing real-world 3D images, the cameras 9 in this embodiment, through a matrix arrangement of multiple cameras and precise pan / tilt control, achieve more comprehensive, accurate, and efficient 3D capture of the target area. This significantly improves work efficiency and overcomes issues such as limited viewing angles, distortion, and uneven image quality in traditional methods, ensuring the integrity and authenticity of the captured data.
[0030] The three shooting cameras 9 are arranged in sequence on the outside of the Y-axis adjustment rod 7. The upper shooting camera 9 looks up to shoot, the middle shooting camera 9 looks straight ahead to shoot, and the lower shooting camera 9 looks down to shoot. The viewing direction is at a 45-degree angle or vertical to the wall. The fixed bracket 1 can be replaced with an unmanned vehicle, and the unmanned vehicle is controlled to move using a remote control to detect different surfaces. There is no need to manually carry the fixed bracket 1. The three photos taken in the same direction and position by the three shooting cameras 9 are later fused and optimized into one photo. The optimized photos taken in different directions and positions are used to generate a real-life three-dimensional model.
[0031] Specifically, by switching between the fixed bracket 1 and the remote control car, the camera can be moved more flexibly, making it easier to perform three-dimensional shooting;
[0032] The shooting camera 9 consists of three 4 / 3 CMOS cameras (equipped with 24mm lenses).
[0033] Working Principle: During operation, the fixed bracket 1 or unmanned vehicle is first adjusted using a level 2, ensuring that the horizontal plane of the quick-release bracket is perpendicular to the acquisition surface. A three-axis leveler and leveling lock knob are used to ensure the stability of the entire setup. The camera 9 is then mounted on the Y-axis adjustment rod 7 at a specific angle (the top camera looks upward, the middle camera looks straight ahead, and the bottom camera looks downward). The PTK measuring instrument 10 is used to obtain real-time 3D positioning results, improving the accuracy of the acquired data.
[0034] During the acquisition process, the rotation of the Z-axis adjustment rod 5 is controlled to achieve shooting at different angles. Specifically, the middle shooting camera 9 is first directed toward the acquisition surface to shoot three photos. Then, the Z-axis adjustment rod 5 is controlled to rotate 45 degrees clockwise and 90 degrees counterclockwise, and three photos are taken by the three shooting cameras (9) respectively. In this way, nine photos can be obtained in each direction (three photos for each of the three cameras), thereby achieving full coverage of the target area.
[0035] After the capture is complete, the three photos taken in the same direction and position are fused and optimized to produce a single high-quality photo. Finally, these optimized photos are combined with the 3D positioning data measured by the PTK measuring instrument 10 to generate a real-world 3D model.
[0036] In addition, the utility model also provides the option of using an unmanned vehicle to replace the fixed bracket 1, so that when detecting different surfaces, there is no need to manually carry the fixed bracket 1, and only the remote control can be used to control the vehicle, further improving the flexibility and convenience of collection.
