Description

Technical Field

[0001] This utility model relates to the field of lens technology, and in particular to a panoramic camera lens. Background Technology

[0002] In formal meetings, to ensure complete recording and subsequent review of the meeting content, it is often necessary to record the entire session on video. While commonly used cameras can meet basic recording requirements in terms of image quality and focus, their field of view is usually limited, covering only the area directly in front. For larger meeting settings, such as large roundtables, forums, or lecture halls, a single camera lens cannot fully capture all participants and key details. Therefore, in practice, a multi-lens shooting approach is often used, deploying multiple cameras in the center or key locations of the venue to expand the overall shooting coverage.

[0003] However, multi-lens systems also bring new challenges. Firstly, there's the issue of blind spots between devices; areas where adjacent lenses don't completely overlap can easily miss parts of the image, leading to the loss of important content. Secondly, installing multiple devices requires significant space, interfering with venue setup and participant movement, thus impacting the overall meeting environment. On the other hand, the relative positions and angles between lenses require precise adjustments, which is not only time-consuming and labor-intensive in practice but also demands a certain level of technical expertise. Otherwise, issues such as image misalignment and unnatural stitching may arise, further increasing the complexity of meeting preparations. Utility Model Content

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] A panoramic camera lens includes: a first lens 1, a second lens 2, a sensor plate 3, and a baffle 4. The first lens 1 is hemispherical. The baffle 4 is fastened to the top of the first lens 1, so that the imaging area of ​​the first lens 1 is a hollow ring. The first lens 1, the second lens 2, and the sensor plate 3 are arranged sequentially along the vertical direction, so that light passes through the first lens 1, the second lens 2, and the sensor plate 3 in sequence.

[0020] In practical applications, this invention is placed in the center of the conference room. Because the first lens 1 is hemispherical, it can capture light within one hemisphere. Specifically, the top of the first lens 1 faces the ceiling of the conference room; the content in this area is not essential and is therefore blocked by the baffle 4. Thus, the imaging area of ​​the first lens 1 is a hollow ring, effectively covering the main area of ​​the conference room. When light enters the first lens 1, it is compressed and then enters the second lens 2, where it is corrected. Finally, the light is projected onto the sensor plate 3, which forms the corresponding image. In summary, this invention allows for the capture of the entire conference room area with a single lens, eliminating the need for multi-lens stitching. This effectively avoids missing important areas and also eliminates the need for lens calibration.

[0021] It also includes a mounting housing 5. The mounting housing 5 is connected to the first lens 1. The mounting housing 5 is fastened to the first lens 1. A gap is provided between the mounting housing 5 and the baffle 4 so that the first lens 1 can acquire the imaging area. Specifically, the first lens 1 is provided with a snap-fit ​​protrusion 11. The snap-fit ​​protrusion 11 surrounds the first lens 1. The snap-fit ​​protrusion 11 is fixedly connected to the first lens 1. The snap-fit ​​protrusion 11 and the first lens 1 are stepped. The mounting housing 5 is provided with a groove corresponding to the snap-fit ​​protrusion 11. The mounting housing 5 is fastened to the snap-fit ​​protrusion 11 through the groove.

[0022] The first lens 1 is assembled by the assembly housing 5. Meanwhile, the bottom of the first lens 1 faces the table of the conference room. Since this content is not essential, the bottom of the first lens 1 is covered by the assembly housing 5, so that the shooting area of ​​the first lens 1 can meet the actual requirements.

[0023] It also includes an image processing module 6. The image processing module 6 is located on the side of the sensor board closest to the ground. The image processing module 6 is electrically connected to the sensor board 3.

[0024] After receiving light and forming an image, sensor board 3 transmits the formed image to image processing module 6 for further processing.

[0025] It also includes a snap-fit ​​structure 7. The snap-fit ​​structure 7 includes a positioning post 71, a snap-fit ​​rod 72, and a spring 73. The positioning post 71 is embedded in the first lens 1. A cavity for accommodating the snap-fit ​​rod 72 is formed inside the positioning post 71. One end of the snap-fit ​​rod 72 is connected to the baffle 4. The other end of the snap-fit ​​rod 72 is snapped into the positioning post 71. The spring 73 is disposed inside the positioning post 71. One end of the spring 73 abuts against the inner wall of the positioning post 71. The other end of the spring 73 abuts against the snap-fit ​​rod 72. Specifically, the snap-fit ​​rod 72 passes through the baffle 4. A connecting plate 721 is provided on the snap-fit ​​rod 72. There are two connecting plates 721. The connecting plates 721 are parallel to each other. The connecting plates 721 are spaced apart. A retaining plate 41 is provided inside the baffle 4. The retaining plate 41 fits against the snap-fit ​​rod 72. The retaining plate 41 is located between the connecting plates 721. Meanwhile, a positioning plate 722 is also provided on the locking rod 72. The positioning plate 722 is perpendicular to the locking rod 72. An extension groove 711 and a positioning groove 712 are formed inside the positioning post 71. The extension groove 711 is formed vertically. The cross-section of the extension groove 711 corresponds to the cross-section of the positioning plate 722. The extension groove 711 and the positioning groove 712 are connected. The positioning groove 712 is formed horizontally. The positioning groove 712 can accommodate the positioning plate 722.

[0026] In practice, the larger the conference room area, the larger the corresponding ceiling area, and the larger the required baffle plate 4 area. Therefore, baffle plate 4 needs to be replaced when necessary. A slotted groove is provided at the end of the locking rod 72, allowing operators to manipulate it using a flathead screwdriver. The operator rotates the locking rod 72 with the screwdriver, causing the positioning plate 722 to rotate within the positioning groove 712. When the positioning plate 722 rotates to the point where the positioning groove 712 connects to the extension groove 711, the spring force of the spring 73 is released, pushing the locking rod 72 to slide relative to the positioning post 71. At this time, the positioning plate 722 enters the extension groove 711. Simultaneously, as the locking rod 72 slides, it drives the connecting plate 721 to move synchronously, causing the locking plate 41 to engage with one of the connecting plates 721. At this point, one end of the locking rod 72 protrudes beyond the baffle plate 4. The operator can then pull the locking rod 72, causing it to slide the positioning plate 722 along the extension groove 711, ultimately disengaging the locking rod 72 from the positioning post 71. Simultaneously, the locking plate 41 is restricted by the connecting plate 721, so pulling the locking rod 72 allows the retaining plate 4 to be removed. Reversing the operation allows the new retaining plate 4 to be installed on the first lens 1. In summary, this method allows for the replacement of the retaining plate 4. Furthermore, the operator's hands or tools do not directly contact the first lens 1 throughout the process, minimizing wear and tear on the first lens 1 and extending its service life to some extent.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
