[0002] In the fields of security monitoring, traffic management, environmental monitoring, etc., cameras, as core surveillance equipment, play an extremely important role. Traditional surveillance systems usually rely on a single camera or a limited camera array to achieve real-time monitoring of a specific area. These cameras are designed to capture video streams for real-time observation or subsequent analysis in order to enhance security, monitor traffic flow, or observe environmental changes. However, the effectiveness of these systems depends largely on the performance of the camera, the installation location, and the viewing angle range, which directly affect the monitoring quality and coverage.

[0003] In order to improve monitoring effects and achieve more comprehensive area coverage, multi-view camera technology has emerged in recent years. This technology aims to provide a wider range of scene information by using multiple lenses to capture images from different angles. Although multi-view cameras have made progress in improving field of view coverage and image capture details, they still face the challenge of limited viewing angles. The lenses of multi-view cameras are usually fixed, which means that although images can be captured from multiple angles, the field of view of each lens is still limited and often cannot cover a wider area.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-9 The utility model provides a multi-camera device, including a mounting seat 1, a first camera 2, a second camera 3 and a third camera 4, wherein the first camera 2 and the second camera 3 are both fixedly mounted on the mounting seat 1; the multi-camera device also includes a driving cavity 5, a first driving mechanism 6 and a second driving mechanism 7; the driving cavity 5 is rotatably connected to the mounting seat 1, the first driving mechanism 6 is installed inside the driven cavity 5, and is used to drive the driving cavity 5 to rotate 360 ​​degrees relative to the mounting seat 1, the third camera 4 is rotatably connected to the side wall of the driving cavity 5, and the second driving mechanism 7 is arranged inside the driving cavity 5, and is used to drive the third camera 4 to rotate 90 degrees.

[0027] Among them, the first camera 2 adopts a long-distance 40x zoom, 4 million pixel camera core, which ensures that the first camera 2 can effectively magnify and clearly capture detailed information of hidden danger points when monitoring long-distance targets, greatly enhancing the monitoring system's ability in long-distance monitoring. The second camera 3 adopts a 2 million pixel camera with night vision enhancement. The second camera 3 can effectively monitor the state of the scene in an environment with extremely low light, ensuring the continuity and effectiveness of night monitoring. The third camera 4 adopts a 24 million pixel panoramic camera to achieve high-definition scene monitoring. Furthermore, during use, the multi-eye camera device is installed at a specified position, and the shooting positions of the first camera 2 and the second camera 3 correspond to the specified position. At night, the second camera 3 can effectively shoot. The first driving mechanism 6 is used to drive the driving cavity 5 to rotate 360 ​​degrees in the horizontal direction. The rotation of the driving cavity 5 drives the third camera 4 to rotate. The third camera 4 can shoot in multiple directions. The second driving mechanism 7 is used to directly drive the third camera 4 to rotate 90 degrees in the vertical direction to further adjust the shooting direction of the third camera 4.

[0028] In this embodiment, the first camera 2 and the second camera 3 provide special monitoring in a fixed direction, while the third camera 4 is dynamically adjusted according to the actual monitoring needs to supplement the viewing angle limitations of the fixed camera. This ensures that the monitoring system can simultaneously take advantage of the focus and high resolution of the fixed camera and the flexibility and wide coverage of the movable camera. The dynamic adjustment capability of the third camera 4 is particularly suitable for tracking moving targets or capturing areas that are missed by the fixed camera due to geographical or obstacle restrictions.

[0029] Furthermore, regarding the multi-camera device, the image can be transmitted to the monitoring terminal in real time through the existing image transmission module (image transmission technology) through the existing network interface module, using a wireless or wired network connection. The monitoring terminal can be a large display screen in the central monitoring room, a network cloud platform or a user's mobile device, so that the image can be viewed and stored instantly. By adopting a high-speed data transmission protocol and compression algorithm, the high efficiency and low latency of image data transmission are ensured, so that the monitoring personnel can receive high-quality monitoring images in real time and respond in time. The transmission, display and storage of the above-mentioned monitoring images are technical means well known to those skilled in the art. In addition, this application does not request protection of the related system, so it will not be described in detail.

[0030] As an optional embodiment, a rotating ring 51 is provided on the lower surface of the driving cavity 5, a support portion is extended from the upper end of the rotating ring 51 toward the center of the circle, a first rollable ball 52 is provided on the lower surface of the support portion, and a second rollable ball 53 is provided on the inner wall of the rotating ring 51; a connecting portion 11 is provided on the upper surface of the mounting seat 1, a side surface of the connecting portion 11 is in contact with the second ball 53, and a top surface of the connecting portion 11 is in contact with the first ball 52. During the process of the first driving mechanism 6 driving the mounting cavity 5 to rotate, the rotating ring 51 rotates relative to the mounting seat 1, and the first ball 52 and the second ball 53 both roll, and the rolling of the first ball 52 and the second ball 53 effectively reduces the friction between the rotating ring 51 and the connecting portion 11, thereby reducing the driving resistance of the first driving mechanism 6.

[0031] As an optional embodiment, the first driving mechanism 6 includes a first motor 61, a first gear 62 and a ring gear 63. A mounting groove is provided in the connecting portion 11, and the ring gear 63 is installed in the mounting groove. The first motor 61 is fixedly installed inside the driving cavity 5, and the output end of the first motor 61 is connected to the first gear 62, and the first gear 62 is meshed and connected with the ring gear 63. The first motor 61 is controlled to start, and the output end of the first motor 61 drives the first gear 62 to rotate. The rotation of the first gear 62 rotates relative to the ring gear 63. Since the mounting seat 1 is in a fixed state, the rotation of the first gear 62 drives the mounting cavity 5 to rotate, thereby realizing the driving of the mounting cavity 5.

[0032] As an optional embodiment, the side of the third camera 4 is connected to a rotating shaft 41 extending into the driving cavity 5; the second driving mechanism 7 includes a second motor 71, a second gear 72 and a half gear 73, the second motor 71 is fixedly installed inside the driving cavity 5, the second gear 72 is connected to the output end of the second motor 71, the half gear 73 is connected to the end of the rotating shaft 41 away from the third camera 4, and the second gear 72 is meshed and connected with the half gear 73. The second motor 71 is controlled to start, the output end of the second motor 71 drives the second gear 72 to rotate, the rotation of the second gear 72 drives the half gear 73 to rotate, and the rotation of the half gear 73 drives the rotating shaft 41 to rotate, thereby realizing the driving of the rotating shaft 41.

[0033] As an optional embodiment, a controller 54 for controlling the first drive mechanism 6 and the second drive mechanism 7 is disposed inside the drive cavity 5. The controller 54 receives instructions from outside the system (such as user input or preset automation script) and sends instructions to the first drive mechanism 6 and the second drive mechanism 7. The controller 54 controls the first drive mechanism 6 and the second drive mechanism 7 to start, stop, forward or reverse. The controller 54 can be, but is not limited to, an existing PLC (programmable logic controller).

[0034] As an optional embodiment, the third camera 4 is provided with a wiper 8. The wiper 8 is used to scrape off water or debris on the lens surface of the third camera 4. The wiper 8 can be an existing wiper, such as a wiper that currently drives a wiper strip to swing through a motor and a connecting rod.

[0035] As an optional embodiment, a clamping mechanism 12 is provided on the lower surface of the mounting seat 1, and the clamping mechanism 12 includes a mounting box body 121, a bidirectional screw 122, two guide rails 123 and two clamping plates 124. The mounting box body 121 is fixedly connected to the lower surface of the mounting seat 1, and the bottom wall of the mounting box body 121 is provided with two slide grooves 125. The upper ends of the two clamping plates 124 extend into the two slide grooves 125 and are slidably connected to the two guide rails 123. The bidirectional screw 122 is rotatably installed inside the mounting box body 121, and the bidirectional screw 122 is threadedly connected to the two clamping plates 124. One end of the bidirectional screw 122 is connected to a handwheel 126 extending out from the side wall of the mounting box body 121. When installing the multi-eye camera, two clamping plates 124 are set on the mounting rod, and then the hand wheel 126 is rotated. The rotation of the hand wheel 126 drives the bidirectional screw 122 to rotate, and the rotation of the bidirectional screw 122 drives the two clamping plates 124 to move closer to each other. When the two clamping plates 124 are in close contact with the mounting rod, the installation of the mounting base 1 is completed.

[0036] As an optional embodiment, a multi-camera device also includes a power supply module 9, which includes a solar panel 91, a support 92 and a battery 93, wherein the battery 93 is connected to the support 92, the solar panel 91 is connected to the upper end of the support 92, and the solar panel 91 is inclined, and the battery 93 supplies power to the first camera 2, the second camera 3, the third camera 4, the first drive mechanism 6 and the second drive mechanism 7 through a wire 94.

[0037] The support 92 serves as a supporting structure for the solar panel 91 and the battery 93.

[0038] The solar panel 91 is used to charge the battery 93, which is the energy storage component of the power supply module. It is connected to the support 92 and charged by the solar panel 91. The main function of the battery 93 is to store the electric energy generated by the solar panel 91 for use when the sun is insufficient or at night. This ensures that the camera device can continue to work even when there is no sunlight. The wire 94 is used to connect the battery 93 and the various components of the camera device, including the first camera 2, the second camera 3, the third camera 4, and the first and second drive mechanisms 6 and 7. These wires ensure that the electric energy is smoothly and continuously delivered from the battery 93 to the various components to provide them with the required power. It should be noted that in the specific implementation of the utility model, considering that the solar panel 91 may face the situation of low power generation efficiency at night or on rainy days, in addition to using the power supply module 9, it should also be connected to the mains to ensure that the multi-eye camera device can continue to operate stably when the solar power supply is insufficient.

[0039] As an implementation method, the multi-camera device is deployed in key areas of the railway "four power" project, such as monitoring points such as the roofs of four power houses. The railway "four power" project, including communication, signal, power and electric traction power supply systems, constitutes the core functional support and energy supply foundation of the high-speed railway network. Among them, the "four power equipment" is usually concentrated in the four power houses. The security monitoring of these houses is crucial to ensure the stable operation of the entire railway system.

[0040] Given the wide distribution of the railway network, the environmental conditions it faces are changeable and demanding, including extreme temperature fluctuations, and conventional camera equipment often cannot meet the stable operation and monitoring needs in these environments. Therefore, the use of this multi-camera device, combined with its high-definition shooting, excellent performance in low-light environments, and the ability to capture a wider angle of view through dynamic adjustment, provides an efficient solution for the monitoring needs of the railway "four electricity" project. This not only strengthens the monitoring capabilities of the four electricity houses and their key equipment, but also ensures the efficiency and reliability of the monitoring system in a wide range and complex railway application environments.

[0041] The specific implementation is to connect the multi-camera device with the existing intelligent analysis module, control module and communication module. The intelligent analysis module can be but not limited to the Huawei Atlas 200 acceleration module, which converts the hidden danger photos into warning information after function recognition. The control module is used to send a control signal to the controller 54, and control the first drive mechanism 6 to drive the drive cavity 5 to rotate 360 ​​degrees in the horizontal direction through the controller 54, and control the second drive mechanism 7 to directly drive the third camera 4 to rotate 90 degrees in the vertical direction. The communication module is used to send the warning information identified and converted by the intelligent analysis module to the monitoring center or related emergency response system for real-time information sharing and rapid response. And receive control instructions from the monitoring center or remote operators, and then adjust the shooting angle of the camera device or perform other related operations.

[0042] In the prior art, the intelligent analysis module realizes real-time analysis and processing of images based on deep learning and artificial intelligence (AI) algorithms.

[0043] Furthermore, the intelligent analysis module includes but is not limited to:

[0044] AI processor: The AI ​​processor built into the Huawei Atlas 200 acceleration module is specially optimized for the computing efficiency of deep learning algorithms and provides powerful image and video analysis capabilities.

[0045] Deep learning framework: Supports mainstream deep learning frameworks such as TensorFlow and PyTorch, making it easier for developers to build and deploy complex AI models.

[0046] Pre-trained model library: Provides a rich collection of pre-trained models, such as models for object detection, image classification, face recognition, etc., which can be directly applied or fine-tuned according to specific needs.

[0047] In practice, after the image data is collected by the camera, it is first preprocessed, such as resizing and normalization, to meet the input requirements of the AI ​​model. The preprocessed image data is input into the deep learning model, and the model extracts the features of the image through a multi-layer neural network. These network layers include convolutional layers, activation layers, and pooling layers, which can capture image features from simple to complex. The extracted features are sent to the subsequent layers of the model for analysis. Based on the knowledge learned during the training process, the AI ​​model performs tasks such as classification, detection, or recognition of the image to identify objects, scenes, or specific events in the image. The analysis results are output as specific information, such as images marked with the detected objects, classification labels, or event warnings. This information can then be used for further processing or directly fed back to the user. The core principle of the intelligent analysis module is to use deep learning algorithms to automatically learn patterns and features in images without manually writing rules. Deep neural networks can learn complex image representations through a large amount of training data, thereby achieving high-accuracy analysis and recognition of new images.

[0048] In this embodiment, a multi-camera device is deployed on the roofs of the four power houses of the railway "four power" project, mainly used to monitor the integrity of the house structure, such as skin peeling, bulging, roof deformation and other problems, which are important indicators that may cause water leakage and other safety hazards. The first camera 2 is used to capture details at a long distance, such as the surrounding environment and the conditions outside the house, as well as factors that may affect safety at a distance. The second camera 3 is used to work under low light conditions, specifically monitoring the status of the house at night or in dark weather, ensuring 24-hour monitoring coverage. The third camera 4 is controlled by the first drive mechanism 6 and the second drive mechanism 7 to achieve all-round dynamic monitoring, especially for accurate shooting of problems such as house skin, bulging and deformation.

[0049] The image data is transmitted to the intelligent analysis module in real time. The intelligent analysis module uses a deep learning algorithm to analyze the image and identify abnormal structural features, such as skin shedding, bulging or deformation. This process relies on a pre-trained machine learning model that can learn from a large amount of image data what image features represent potential safety hazards. Once the intelligent analysis module identifies potential problems, it will immediately convert the images of these problems into early warning information. This information is then sent to the monitoring center or directly notified to the maintenance team through the communication module. In addition, the control module can also receive instructions from the monitoring center and adjust the shooting angle or focal length of the camera through the controller 54 to obtain more detailed image data and further confirm the specific situation of the problem.
