Description

Technical Field

[0001] This utility model relates to the field of video monitoring equipment technology, and more specifically, to a video anomaly detection device based on continuous video. Background Technology

[0002] In the field of video surveillance, ensuring the continuous stability and accuracy of camera footage is crucial for security monitoring. With the continuous expansion of monitoring scope and the increasing complexity of application scenarios, the need to promptly detect and address anomalies in camera footage is becoming increasingly urgent.

[0003] Application CN 112804520 A discloses a method for high-speed surveillance video quality detection, which includes functions such as black screen detection, occlusion detection, blur detection, brightness anomaly detection, and color anomaly detection. However, this method has certain limitations. In terms of black screen detection, for current cameras, the screen usually has subtitles when there is no signal, and is not completely black, which makes its black screen detection range narrow. Occlusion detection uses the Laplacian operator to extract edge feature information, which is sensitive to noise and is prone to misjudgment. At the same time, this method does not consider the presence of noise or stripe anomalies in the image, as well as the jitter and displacement of the surveillance camera image.

[0004] Existing image anomaly detection devices often encounter problems in complex environments, such as blurred images or partial obstructions caused by dust and dirt on the camera lens. These devices are unable to effectively and promptly clean themselves, affecting the accuracy and timeliness of detection. Furthermore, some detection devices lack coordination in data processing, anomaly detection, and cleanup control, making it difficult to efficiently handle various abnormal scenarios in practical applications. To overcome these problems, this invention provides an image anomaly detection device based on continuous video, capable of accurately monitoring and promptly cleaning camera image anomalies, effectively improving the reliability and stability of the detection device in complex environments. Utility Model Content

[0005] The purpose of this invention is to provide a continuous video-based image anomaly detection device to address the shortcomings of existing image anomaly detection devices mentioned in the background art. These devices often fail to effectively and promptly clean themselves when faced with complex environments, such as camera lenses becoming contaminated with dust or dirt, leading to blurred images or partial obstructions. This affects the accuracy and timeliness of detection. Furthermore, some detection devices lack coordination in data processing, anomaly judgment, and cleaning control, making it difficult to efficiently handle various anomaly scenarios in practical applications.

[0006] To achieve the above objectives, this utility model provides a continuous video-based image anomaly detection device, including an image anomaly monitoring module. The image anomaly monitoring module is installed on a camera, and a lens cleaning component is also installed on the upper part of the camera. The image anomaly monitoring module is used to monitor image anomalies in the camera, control the lens cleaning component to clean the camera's shooting end, and transmit an alarm signal to the background through a signal transmitter.

[0007] This setup includes an image anomaly detection module 3 installed on camera 1, capable of acquiring real-time image information captured by camera 1. When the image anomaly detection module 3 detects an anomaly in the image from camera 1, it sends a control signal to the lens cleaning component 2 to initiate a cleaning action; simultaneously, it sends an alarm signal to the backend via signal transmitter 4. Its core principle lies in constructing a multi-tasking processing system that tightly integrates image monitoring, anomaly handling, and information transmission, forming an orderly workflow capable of providing a rapid and comprehensive response to camera image anomalies.

[0008] Preferably, the image anomaly monitoring module includes a data receiving module, a data processing module, and a cleaning control module. The camera is equipped with an image capture module and a data output module. The image capture module is used to capture the image captured by the camera and transmit the data to the data processing module through the data output module and the data receiving module. The data processing module analyzes the data and, after determining the anomaly, controls the lens cleaning component through the cleaning control module to clean the camera's shooting end.

[0009] This feature is located inside camera 1. The image capture module 13 captures continuous video footage at regular time intervals or according to specific rules, obtaining a series of discrete image data. This data is transmitted to the data processing module 32 via the data output module 14, which interfaces with the data receiving module 31 in the image anomaly monitoring module 3. The data processing module 32 uses specific algorithms and data analysis models to perform in-depth analysis of the received data, such as comparing the differences in image clarity, brightness, color distribution, and other characteristics with those under normal conditions to determine if any anomalies exist. If an anomaly is detected, the cleaning control module 33 sends a control signal to the lens cleaning component 2 based on the received instructions, driving it to perform a cleaning operation. This process, through data transmission and collaborative work between modules, achieves an automated workflow from image acquisition to anomaly detection and cleaning control.

[0010] Preferably, the lens cleaning component includes a cleaning brush, which is mounted on a mounting plate and rotated by a cleaning motor to clean the shooting end.

[0011] When the cleaning motor 23 in the lens cleaning component 2 is powered on, the motor's rotating shaft drives the connected cleaning brush 21 to rotate. Since the cleaning brush 21 is mounted on the mounting plate 22, the mounting plate 22 relatively stably fixes the position of the cleaning brush 21, allowing the cleaning brush 21 to clean the shooting end 11 of the camera 1 in a stable posture during rotation. The principle is based on the rotational power of the motor being converted into the circular motion of the cleaning brush 21. The contact friction between the cleaning brush 21 and the surface of the shooting end 11 removes dust, stains, and other impurities from the lens surface, thereby achieving the purpose of cleaning the lens.

[0012] Preferably, the mounting plate is driven by a linear screw component to move linearly, thereby enabling it to approach and separate from the shooting end.

[0013] This linear lead screw component 24 consists of a motor, lead screw, nut, and other components. When the motor of the linear lead screw component 24 is powered on, the rotational motion of the motor is converted into the linear motion of the nut through the lead screw and nut pair. Since the mounting plate 22 is fixedly connected to the nut, the mounting plate 22 will move linearly with the linear motion of the nut, thereby realizing the approach or separation of the cleaning brush 21 mounted on it from the camera 1's shooting end 11. This linear motion control principle can precisely adjust the distance between the cleaning brush 21 and the shooting end 11, meeting the needs of cleaning position and force in different cleaning scenarios.

[0014] Preferably, the cleaning brush is made of sponge material, and the front of the cleaning brush is provided with a groove, the inner wall of the groove being adapted to the outer wall of the shooting end.

[0015] The cleaning brush 21 on the top is made of sponge material, which has good flexibility and water absorption. The groove on its front is customized according to the shape and size of the outer wall of the camera 1's shooting end 11, so that the inner wall of the groove can fit tightly against the outer wall of the shooting end 11. When the cleaning brush 21 contacts the shooting end 11 during rotation, the flexibility of the sponge material allows it to adapt to the curved shape of the lens and fully contact all parts of the lens surface; at the same time, the water absorption of the sponge helps to absorb the small particles and liquid stains on the lens surface, and the groove's fitting design further enhances the friction between the cleaning brush 21 and the lens, improving the cleaning effect.

[0016] Preferably, the housing of the linear lead screw component is rotatably connected to a fixed seat via a rotating shaft. The fixed seat is fixed to the housing of the camera. The rotating shaft is driven by a motor to rotate, thereby enabling the lens cleaning component to flip upward and avoid obstructing the camera when not cleaning.

[0017] In this configuration, the housing of the linear lead screw component 24 is rotatably connected to the fixed base 25 via a rotating shaft 26, and the fixed base 25 is securely fixed to the housing of the camera 1. When the motor driving the rotating shaft 26 is powered on, the rotation of the motor causes the rotating shaft 26 to rotate, thereby causing the linear lead screw component 24 connected to the rotating shaft 26 and the entire lens cleaning component 2 mounted on the linear lead screw component 24 to flip upwards. By controlling the forward and reverse rotation of the motor and the rotation angle, the flipping state of the lens cleaning component 2 can be precisely controlled. When cleaning is needed, it can be flipped to a suitable position for cleaning operations, and when cleaning is not needed, it can be flipped and stored away to avoid obstructing the camera 1's line of sight.

[0018] Preferably, one end of the camera is fixed to an object via a mounting bracket.

[0019] In this setup, one end of camera 1 is connected to a fixed object via mounting bracket 12, which serves both as a connection and a fixation point. Mounting bracket 12 is typically secured to the fixed object using bolts, welding, or other fastening methods, and simultaneously tightly connected to camera 1 through a specific interface or structure, stably fixing camera 1 in the desired position. The principle is to utilize the rigid structure and reliable connection of mounting bracket 12 to provide stable support for camera 1, preventing displacement or shaking due to external factors (such as wind or vibration) during operation, thus ensuring the camera can continuously and stably capture images of the specific area.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This continuous video-based anomaly detection device first achieves real-time monitoring and coordinated processing of video anomalies. Through the collaborative work of the anomaly detection module and the camera, the image capture module continuously captures and transmits the captured images to the data processing module. The data processing module can quickly analyze and determine whether there are any anomalies in the image. Once an anomaly is detected, it can both drive the lens cleaning component to clean the image through the cleaning control module and send an alarm signal to the backend through the signal transmitter, forming a complete closed loop of "monitoring-judgment-processing-alarm". This solves the problem that traditional detection devices can only monitor but cannot process anomalies in a timely manner, greatly improving the response efficiency of the monitoring system.

[0022] Secondly, the lens cleaning component's structural design combines efficiency and protection. The cleaning brush is made of sponge material, and its front has a groove that fits the outer wall of the shooting end. This ensures full contact with the shooting end during cleaning, improving the cleaning effect, while preventing hard materials from scratching or damaging the lens. The linear screw component drives the mounting plate to move linearly, precisely controlling the approach and separation of the cleaning brush from the shooting end to meet different cleaning needs. The rotating shaft drives the lens cleaning component to flip upwards, allowing it to be stored away when not in use. This effectively avoids obstructing the camera's line of sight, ensuring uninterrupted shooting and solving the problem of cleaning components easily affecting shooting. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This invention provides a device for detecting image anomalies in continuous video, such as... Figure 1 As shown, it includes an image anomaly monitoring module 3, which is installed on the camera 1. A lens cleaning component 2 is also installed on the upper part of the camera 1. The image anomaly monitoring module 3 is used to monitor image anomalies of the camera 1, control the lens cleaning component 2 to clean the shooting end 11 of the camera 1, and send an alarm signal to the background through the signal transmitter 4.

[0030] The image anomaly monitoring module 3 is installed on camera 1 and can acquire the image information captured by camera 1 in real time. When the image anomaly monitoring module 3 detects an anomaly in the image of camera 1, it sends a control signal to the lens cleaning component 2 to initiate the cleaning action; at the same time, it sends an alarm signal to the backend through the signal transmitter 4. Its core principle lies in building a multi-task processing system that tightly integrates image monitoring, anomaly handling, and information transmission into an orderly workflow, enabling a rapid and comprehensive response to camera image anomalies. This gives the entire device the ability to self-process anomalies and report information in a timely manner. Timely lens cleaning can quickly restore camera 1 to its normal shooting state, avoiding the loss or inaccuracy of monitoring data due to image anomalies, and ensuring the continuity and reliability of monitoring. Sending an alarm signal to the backend allows relevant personnel to be informed of the situation on site in a timely manner and take further measures, such as checking the specific anomaly and conducting more in-depth inspection and maintenance of the equipment, which greatly improves the security and early warning capabilities of the monitoring system and effectively reduces safety hazards caused by equipment failure or anomalies.

[0031] In this embodiment, as Figure 3 As shown, the image anomaly monitoring module 3 includes a data receiving module 31, a data processing module 32, and a cleaning control module 33. The camera 1 is equipped with an image capture module 13 and a data output module 14. The image capture module 13 is used to capture the image captured by the camera 1 and transmits the data to the data processing module 32 through the data output module 14 and the data receiving module 31. The data processing module 32 performs data analysis and, after determining the anomaly, controls the lens cleaning component 2 through the cleaning control module 33 to clean the shooting end 11 of the camera 1.

[0032] Inside camera 1, the image capture module 13 captures continuous video footage at regular time intervals or according to specific rules, obtaining a series of discrete image data. This data is transmitted to the data processing module 32 via the data output module 14, which interfaces with the data receiving module 31 in the image anomaly monitoring module 3. The data processing module 32 uses specific algorithms and data analysis models to perform in-depth analysis of the received data, such as comparing the differences in image clarity, brightness, color distribution, and other characteristics with those under normal conditions to determine if any anomalies exist. If an anomaly is detected, the cleaning control module 33 sends a control signal to the lens cleaning component 2 based on the received instructions, driving it to perform a cleaning operation. This process, through data transmission and collaborative work between modules, achieves an automated workflow from image acquisition to anomaly judgment and cleaning control. This modular collaborative design principle results in efficient and accurate anomaly detection and processing. The image capture module 13 and the data output module 14 ensure that image data is transmitted to the processing module in a timely and accurate manner, providing sufficient analysis material for the data processing module 32. The data processing module 32 uses professional algorithms to accurately identify various types of image anomalies, which is more efficient and less prone to errors compared to manual judgment. The cleaning control module 33 promptly drives the lens cleaning component 2 to work, greatly shortening the time from the discovery of the abnormality to its resolution, improving the device's ability to cope with abnormal situations, and ensuring that the camera 1 can continuously output high-quality monitoring images.

[0033] Specifically, such as Figure 2 As shown, the lens cleaning component 2 includes a cleaning brush 21, which is mounted on the mounting plate 22. The cleaning brush 21 is driven to rotate by the cleaning motor 23 to clean the shooting end 11.

[0034] When the cleaning motor 23 in the lens cleaning component 2 is powered on, the motor's rotating shaft drives the connected cleaning brush 21 to rotate. Since the cleaning brush 21 is mounted on the mounting plate 22, the mounting plate 22 relatively stably fixes the position of the cleaning brush 21, allowing the cleaning brush 21 to clean the shooting end 11 of the camera 1 in a stable posture during rotation. The principle is based on the motor's rotational power being converted into the circular motion of the cleaning brush 21. The contact friction between the cleaning brush 21 and the surface of the shooting end 11 removes dust, stains, and other impurities from the lens surface, thus achieving the purpose of cleaning the lens. The rotating cleaning brush 21 design makes the cleaning process more efficient. Compared to traditional manual wiping or simple scraping cleaning methods, the rotating cleaning brush 21 can cover a larger lens area in a shorter time, improving cleaning efficiency. At the same time, the stable mounting structure ensures the stability of the cleaning brush 21 during rotation, avoiding additional damage to the shooting end 11 due to shaking or deviation. While effectively cleaning the lens, it protects the optical components of the camera 1, extends the service life of the camera 1, and further ensures the clarity and stability of the monitoring image.

[0035] Furthermore, such as Figure 2 As shown, the mounting plate 22 is driven to move linearly by the linear screw component 24, thereby moving closer to and away from the shooting end 11.

[0036] The linear lead screw assembly 24 consists of a motor, a lead screw, and a nut. When the motor of the linear lead screw assembly 24 is energized, the rotational motion of the motor is converted into the linear motion of the nut through the lead screw and nut pair. Since the mounting plate 22 is fixedly connected to the nut, the mounting plate 22 will move linearly with the linear motion of the nut, thereby realizing the approach or separation of the cleaning brush 21 mounted on it from the camera 1's shooting end 11. This linear motion control principle can precisely adjust the distance between the cleaning brush 21 and the shooting end 11, meeting the needs of cleaning position and force in different cleaning scenarios. The design of the linear lead screw assembly 24 driving the mounting plate 22 provides precise position control for lens cleaning operations. When cleaning the lens, the movement of the mounting plate 22 can be precisely controlled to ensure that the cleaning brush 21 accurately fits against the surface of the shooting end 11, guaranteeing the cleaning effect. After cleaning, the cleaning brush 21 can be removed in time to avoid potential effects from prolonged contact with the shooting end 11, such as obstructing part of the shooting field of view or causing wear on the surface of the shooting end 11 due to long-term contact. This effectively improves the adaptability and reliability of the lens cleaning component 2 in different working stages.

[0037] Furthermore, such as Figure 2 As shown, the cleaning brush 21 is made of sponge material, and the front of the cleaning brush 21 has a groove, the inner wall of which is adapted to the outer wall of the shooting end 11.

[0038] The cleaning brush 21 is made of sponge material, which has excellent flexibility and water absorption. The groove on its front is custom-designed to fit the shape and size of the outer wall of the camera 1's shooting end 11, allowing the inner wall of the groove to fit snugly against the outer wall of the shooting end 11. When the cleaning brush 21 rotates and contacts the shooting end 11, the flexibility of the sponge material allows it to adapt to the curved shape of the lens, fully contacting all parts of the shooting end 11's surface. Simultaneously, the sponge's water absorption helps to absorb tiny particles and liquid stains from the surface of the shooting end 11, while the groove's fitting design further enhances the friction between the cleaning brush 21 and the shooting end 11, improving the cleaning effect. The sponge material and groove design of the cleaning brush 21 bring several advantages. First, the sponge's flexibility avoids hard scratching of the shooting end 11's surface, protecting the lens's optical coating and glass surface, reducing the risk of damage to the shooting end 11 during cleaning. Second, the sponge's water absorption allows the cleaning process to remove not only solid impurities such as dust but also liquid stains such as oil and moisture, expanding the cleaning brush 21's applicability. The groove's design, which adapts to the outer wall of the camera end 11, greatly improves cleaning efficiency, ensuring that every part of the surface of the camera end 11 can be effectively cleaned. This significantly improves the clarity and quality of the camera image, providing better image data for anomaly detection.

[0039] Furthermore, such as Figure 2 As shown, the housing of the linear lead screw component 24 is rotatably connected to the fixed seat 25 via the rotating shaft 26. The fixed seat 25 is fixed on the housing of the camera 1. The rotating shaft 26 is driven by a motor to rotate, thereby enabling the lens cleaning component 2 to flip upward and avoid obstructing the camera 1 when not cleaning.

[0040] The housing of the linear lead screw component 24 is rotatably connected to the fixed base 25 via the rotating shaft 26, and the fixed base 25 is firmly fixed to the housing of the camera 1. When the motor driving the rotating shaft 26 is powered on, the rotation of the motor drives the rotating shaft 26 to rotate, thereby causing the linear lead screw component 24 connected to the rotating shaft 26 and the entire lens cleaning component 2 mounted on the linear lead screw component 24 to flip upwards. By controlling the forward and reverse rotation of the motor and the rotation angle, the flipping state of the lens cleaning component 2 can be precisely controlled. When cleaning is needed, it can be flipped to a suitable position for cleaning operations, and when cleaning is not needed, it can be flipped and stored to avoid obstructing the camera 1's field of view. The flipping design of the lens cleaning component 2 effectively solves the problem of the cleaning component interfering with the camera 1's shooting when not in operation. When not cleaning, flipping the lens cleaning component 2 upwards and storing it ensures that the camera 1's field of view is not obstructed, guaranteeing the integrity and accuracy of the monitoring image. When lens cleaning is needed, it can be quickly flipped to the working position, making operation simple and quick. This design improves the overall space utilization of the device, optimizes the working environment of camera 1, reduces potential misjudgments caused by the presence of cleaning components, and further enhances the practicality and reliability of the continuous video-based image anomaly detection device.

[0041] Furthermore, such as Figure 1 As shown, one end of camera 1 is fixed to an object via mounting bracket 12.

[0042] One end of camera 1 is connected to a fixed object via mounting bracket 12, which serves both as a connection and a fixation point. Mounting bracket 12 is typically secured to the fixed object using bolts, welding, or other fastening methods, and is also tightly connected to camera 1 through a specific interface or structure, stably fixing camera 1 in the desired position. The principle is to utilize the rigid structure and reliable connection of mounting bracket 12 to provide stable support for camera 1, preventing displacement or shaking due to external factors such as wind or vibration during operation, ensuring that camera 1 can continuously and stably capture images of a specific area. This stable installation method guarantees the stability and reliability of camera 1's operation. During monitoring, the stability of camera 1 is crucial for accurately capturing image details and detecting anomalies. By firmly fixing it to the fixed object via mounting bracket 12, problems such as blurry or jittery images caused by camera 1 shaking are avoided, improving image quality and providing stable and accurate video data to the image anomaly monitoring module 3. This enhances the detection accuracy and efficiency of the entire continuous video-based image anomaly detection device, ensuring continuous and stable operation of the device in various complex environments.

[0043] In use, the continuous video-based anomaly detection device of this invention first activates the camera 1, and its internal image capture module 13 captures continuously captured video images at preset time intervals, such as 1-5 frames per second, generating discrete image data. This data is then connected to the data receiving module 31 in the image anomaly monitoring module 3 via the data output module 14 and transmitted in real time to the data processing module 32, providing raw material for anomaly detection.

[0044] The data processing module 32 uses preset algorithms, such as comparing image clarity thresholds, analyzing brightness fluctuation ranges, and identifying obstructed areas, to analyze the received image data. When blurriness, obstruction, or abnormal brightness is detected, it is determined to be an "image abnormality," and two sets of instructions are generated: one set is sent to the cleaning control module 33 to trigger the lens cleaning process; the other set is converted into an alarm signal through the signal transmitter 4 and transmitted to the background monitoring system to alert relevant personnel.

[0045] The cleaning control module 33 first drives the motor of the rotating shaft 26 to rotate, causing the linear screw component 24 and the entire lens cleaning component 2 to rotate downwards around the fixed base 25 until the cleaning brush 21 is in a working position opposite to the shooting end 11. The motor of the linear screw component 24 starts, driving the mounting plate 22 and the cleaning brush 21 to move linearly towards the shooting end 11 through the screw nut pair until the groove on the front of the cleaning brush 21 fits against the outer wall of the shooting end 11. The rotation speed of the cleaning brush 21 driven by the cleaning motor 23 can be adjusted according to the degree of abnormality, such as 50-100 rpm for slight blurring and 200-300 rpm for severe obstruction. Utilizing the flexibility of the sponge material and the fit of the groove, dust, stains, or moisture on the surface of the shooting end 11 are thoroughly removed. After cleaning, the linear screw component 24 drives the mounting plate 22 in the reverse direction, causing the cleaning brush 21 to separate from the shooting end 11; then the rotating shaft 26 motor reverses, causing the lens cleaning component 2 to rotate upwards and be stored away, avoiding obstruction of the shooting field of view of the camera 1.

[0046] After the cleaning is completed, the image capture module 13 continues to capture images and transmit them to the data processing module 32. If the secondary detection determines that the image has returned to normal, the device returns to the normal monitoring state; if the abnormality is not resolved, the cleaning control module 33 will repeat the cleaning process up to 35 times, and at the same time the signal transmitter 4 will send a "continuous abnormality" alarm to the background, prompting manual intervention to check for conditions such as lens damage or severe contamination.

[0047] Finally, it should be noted that the electronic components in the above-mentioned components, such as camera 1 in this embodiment, are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods.
