[0063] The corresponding terminals of the main control board module 100 are electrically connected to the corresponding terminals of the camera module 200, the projection module 300, and the wireless communication module 400, respectively.
[0064] The projection module 300 includes an optical system, an imaging system, and a projection control system, with the corresponding terminals of the projection control system electrically connected to the corresponding terminals of the optical system and the imaging system, respectively.
[0065] The optical system includes a light source module 1, a leveling lens group 2, a front reflector 3, a rear reflector 5, and an adjustable focus condenser lens group 6, which work together to provide a clear and high-brightness projection effect. At the same time, the adjustable focus condenser lens group 6 allows users to adjust the focal length and clarity of the projected image as needed.
[0066] Furthermore, the display system includes a display module 4, which is composed of an LCD or OLED display screen, providing high-resolution and high-quality image display to meet the image quality requirements in different scenarios.
[0067] Furthermore, the projection control system includes a projection control module 7, which controls the high-speed signal transmission between the light source module 1, the display module 4, and the main control board module 100, ensuring the synchronization and stability of images and videos during capture and projection. The corresponding terminals of the projection control module 7 are electrically connected to the corresponding terminals of the main control board module 100, the light source module 1, and the display module 4, respectively. The projection control module 7 can dynamically adjust the power output of the light source module 1 according to the actual projection requirements, thereby effectively reducing energy consumption and achieving energy saving and environmental protection while ensuring projection quality.
[0068] Furthermore, the light source module 1 is used to emit a white light source with adjustable power; the light source module 1 is capable of emitting a white light source with adjustable power, which allows the system to adjust the light output according to the ambient light and projection requirements, thereby providing an ideal projection effect under different lighting conditions while saving energy.
[0069] The collimating lens group 2 is positioned in the optical path direction of the light source module 1 to straighten the scattered light emitted by the light source module 1, which helps to improve the light utilization efficiency and ensure the brightness and uniformity of the projected image.
[0070] The front reflector 3 is positioned in the optical path direction of the collimating lens group 2 to redirect the straight light after it has been collimated by the collimating lens group 2 by 90°, so that the optical path can be effectively transmitted in a compact space. This is especially important for designing miniaturized and portable camera systems.
[0071] The imaging module 4 is positioned in the optical path direction of the front reflector, and its high-contrast imaging characteristics ensure the clarity and color accuracy of the projected image.
[0072] The rear reflector 5 is positioned in the optical path direction of the display module 4 to rotate the image of the display module by 90°. The 90° rotation function of the rear reflector 5 provides flexible angle adjustment for the projection, allowing the camera system to adapt to different projection surfaces and viewing angles.
[0073] The adjustable focus condenser lens group 6 is positioned in the optical path direction of the rear reflector 5 to project the image from the rear reflector 5 after a 90° rotation. The adjustable focus condenser lens group 6 allows the user to adjust the focal length according to the projection distance and desired clarity, ensuring the clarity and detail of the projected image.
[0074] The front-stage reflector 3 is tilted and forms a 45° angle with the leveling lens group 2; the imaging module 4 is perpendicular to the leveling lens group 2 and forms a 45° angle with the front-stage reflector 3; the rear-stage reflector 5 is tilted and forms a 45° angle with the imaging module 4; the adjustable focusing lens group forms a 45° angle with the imaging module.
[0075] Furthermore, the collimating lens group 2 includes a first collimating lens and a second collimating lens. The first collimating lens is used to initially organize the scattered light emitted by the light source module 1, and the second collimating lens is used to further organize the light after it has been organized by the first collimating lens. The first collimating lens and the second collimating lens are arranged in parallel, and the convex surfaces of the first collimating lens and the second collimating lens are opposite each other. This configuration helps to stabilize the light path and reduce the deviation of light during transmission, thereby improving the stability of the projected image. Through the synergistic effect of the first collimating lens and the second collimating lens, light can be collected and guided more effectively, light loss can be reduced, and light efficiency can be improved.
[0076] Furthermore, the adjustable focusing lens group 6 includes a first focusing lens and a second focusing lens. The first focusing lens is used to initially focus the light rays that are redirected by the stage reflector 5. The second focusing lens is used to further focus the light rays that have been focused by the first focusing lens. The first focusing lens and the second focusing lens are arranged in parallel, and their concave surfaces face each other, which helps to control the light path more precisely, reduce the scattering of light during the focusing process, and thus improve the brightness and contrast of the projected image.
[0077] Furthermore, the wireless communication module 400 is configured as one or more of a WIFI module, Bluetooth module, 2G module, 3G module, 4G module, and 5G module, used to realize wireless data transmission between the camera system and external devices. The wireless communication module 400 supports multiple wireless communication standards such as WIFI, Bluetooth, 2G, 3G, 4G, and 5G, enabling the camera system to adapt to different network environments and user needs. By supporting multiple wireless communication modules, users can remotely access the camera system through different devices (such as smartphones, tablets, laptops, etc.), improving the system's flexibility and convenience. Users can select the most suitable wireless communication module according to actual network conditions and personal preferences to obtain the best user experience.
[0078] Furthermore, in this embodiment, the image sensors in the camera module 200 are responsible for capturing images of the monitored area. These image sensors can be high-resolution to ensure that the captured images have sufficient detail; the images captured by the image sensors are then transmitted to the video encoder. The video encoder encodes the image data into a video stream, which can be in a compressed format for efficient transmission.
[0079] Wireless data transmission: The encoded video stream is transmitted via the wireless communication module 400. This module can be one or more of a WIFI module, Bluetooth module, 2G module, 3G module, 4G module, or 5G module, ensuring that the video stream can be wirelessly transmitted to the user's mobile device or other external devices. Users can remotely access the camera system via an app on their smartphone, tablet, or computer. The app provides a user interface that allows users to view the live video stream, control the camera's direction, zoom, and set other parameters; users can initiate real-time two-way video calls via the app, and the camera system transmits the user's voice and video signals to the monitored area, while simultaneously transmitting the audio and video signals from the monitored area back to the user; shop users can customize images, shop signs, and other information via the app. This information is encoded and transmitted to the camera system, and then projected in real time through the optical and display systems in the projection module 300; the camera system can be set to intelligently link together, automatically projecting pre-configured graphic and text information through the projection module when specific activities (such as human activity or vehicle passage) are detected.
[0080] Optical System Operation: The optical system in the projection module 300 includes a light source module 1, a collimating lens group 2, a front-stage reflector 3, a rear-stage reflector 5, and a condenser lens group 6. The light source module 1 emits white light, which is shaped into straight light by the collimating lens group 2, then redirected by the front-stage reflector 3 and the rear-stage reflector 5, and finally focused and projected onto a predetermined surface by the condenser lens group 6.
