Description
Technical Field
[0001] The present invention belongs to the field of intelligent security technology, and specifically relates to an integrated home security monitoring system and equipment supported by FTTR. Background Art
[0002] In the home environment, on the one hand, the elderly and young children often fall down accidentally. Once a person falls down, if they are not discovered and rescued in time, the injuries to the elderly and young children may be aggravated. On the other hand, as people's living standards continue to improve, it is also required to improve the level of intelligent security protection in the home to prevent strangers from intruding. In addition, for families with pets, when the pet owner goes out, travels on business or travels, it is necessary to know the status of the pet at home in real time. These demands have put forward requirements for video security monitoring and intelligent video analysis and recognition in the home environment.
[0003] At present, video surveillance equipment can realize intelligent analysis of collected video data within a single device and output the monitoring analysis result data of a single video device; or adopt cloud monitoring solutions to transmit collected video data to the cloud, analyze and output result data in the cloud. However, in the case of multiple video surveillance devices installed in a home environment, on the one hand, it is necessary to aggregate the multi-channel video data collected by multiple video surveillance devices and perform correlation analysis based on the multi-channel video data; on the other hand, it is necessary to protect the privacy data of home users and try to avoid uploading privacy data to the cloud. It is necessary to provide service capabilities that can store and analyze user data in the home edge environment.
[0004] Therefore, it is necessary to propose an integrated home security monitoring system and equipment supported by FTTR to at least partially solve the problems existing in the prior art.
[0005] The above information disclosed in this background technology is only used to increase the understanding of the background technology of the present invention and therefore, it may include information that does not constitute the prior art known to ordinary technicians in this field. Summary of the invention
[0006] The purpose of the present invention is to provide an integrated home security monitoring system and equipment supported by FTTR to solve the problems raised in the above background technology.
[0007] To achieve the above object, the present invention provides the following technical solutions: An integrated home security monitoring system supported by FTTR includes: a front-end monitoring module, a data processing module, a user interaction module, an alarm notification module, a network connection module, and a background management module; the front-end monitoring module is used to collect parameter information and indoor and outdoor image information of the home environment in real time, the data processing module is used to receive data from monitoring equipment and integrate and process the data, the user interaction module is used to view the monitoring screen in real time, receive alarm notifications and perform remote control, the alarm notification module is used to issue alarm sounds and flash prompts, and notify users through application push and SMS reminders, the network connection module is used to apply FTTR technology to directly introduce optical fibers into each room, and use high-performance routers and switches at the same time, and the background management module is used to manage user devices and provide technical support and consulting services to users.
[0008] Preferably, the real-time collection of parameter information of the home environment and indoor and outdoor image information: the MQTT protocol is used to collect parameter information of the home environment in real time, and the data of multiple sensors are aggregated and processed through a data fusion algorithm; at the same time, efficient video coding standards and deep learning algorithms are used for image compression processing, and histogram equalization and median filtering are used to improve image quality.
[0009] Preferably, the data received from the monitoring device: the data is preliminarily processed on the existing monitoring device using the lightweight Apache Flink framework, the data processing module is encapsulated into a container using containerization technology, and the container is deployed on the existing monitoring device to run the processing task, and the service quality policy is implemented to prioritize the processing of important application traffic.
[0010] Preferably, the data integration and processing: by equally dividing each layer of the image pyramid into blocks, using the standard deviation to calculate the size of the Hariss value of the feature point, and extracting the expected number of feature points from large to small according to the standard deviation calculation results, using the screened image key frames to generate point cloud data, constructing dense and octree point cloud maps, introducing blockchain technology to store sensor data in blocks, ensuring the integrity and non-tamperability of sensor data, and using data encryption and identity authentication mechanisms to protect users' personal privacy.
[0011] Point clouds include information such as the coordinates and colors of spatial points. Point clouds can be obtained through sensors or synthesized through image frame information. Dense reconstruction requires calculating and using the distance between pixels in the image, and different cameras have different solutions. When constructing a dense map of the home environment, the pixel color information and distance information of the key frame obtained after processing the image information are used to generate a point cloud, and then the point cloud is fused to form a dense point cloud map of the home environment.
[0012] The main steps of the dense point cloud thread are as follows: (1) Extract pixel points from the feature points of the selected image key frames; (2) The pixel coordinate values extracted from the key frame are projected into the spatial coordinate system in combination with the depth information, and point cloud splicing and fusion are performed; (3) Filter out isolated point clouds and point clouds with inaccurate depth, and then construct a map for the remaining point clouds.
[0013] Dense point cloud maps can effectively restore the distribution of objects in a home environment, but the amount of data in point cloud maps is very large, so the octree map is introduced to process important locations separately to reduce the impact of surrounding objects. The basic logic of octree operation: take a certain node as the root node and divide it into eight child nodes; then continue to divide the eight nodes into eight child nodes respectively, and keep looping until all child nodes of a parent node are occupied or no information is stored. At this point, the loop ends and the octree stops dividing, otherwise it will continue to divide nodes.
[0014] The octree child nodes may be affected by noise and appear to be occupied. In order to eliminate the influence of noise, the octree uses a probability-based data method to determine whether a node is occupied. , the probability of not being occupied is , ,make Representation Node The corresponding result of the probability calculation. The conversion relationship between the two is expressed as follows:
[0015] If the node When occupancy is observed, The value will increase, and vice versa. By inversely transforming the above, we can get the following formula, which represents the node Is it occupied?
[0016] When the node When observed multiple times, let the node exist The observed value at time is , the node from the initial time to The logarithmic value of the state probability corresponding to the moment is , then the next moment can be expressed as:
[0017] For Node By adding the logarithmic integral to the observed state, the probability form of the above formula can be expressed as:
[0018] The octree uses the above probability formula to determine whether a node is occupied. When all child nodes of a parent node are occupied or not occupied, the octree stops splitting. Therefore, the octree generally cannot expand all leaf nodes, which can save storage space.
[0019] Preferably, the real-time viewing of monitoring screens and remote control: use WebSocket to achieve real-time two-way communication, transmit sensor data and image streams to the user interface, combine AR technology to display real-time data and monitoring videos of the home environment to users, and provide a user-friendly management interface and operating instructions.

[0022] Preferably, the management of user devices and provision of technical support and consulting services to users includes: using a unified service management platform, integrating sensors and control devices at the software level, performing centralized processing and monitoring, collecting user feedback and suggestions, answering user questions, generating data analysis reports to help understand user behavior and device performance, and supporting decision making.

[0024] A computer-readable storage medium having a computer program stored thereon, wherein when the computer program is executed by at least one processor, the at least one processor implements an integrated home security monitoring system supported by FTTR as described above.

[0044] Let the expected value of each feature point square be With minimum extraction value If the result is greater than 0, only the previous If the result is less than 0, the lowest extraction value of After extracting the number of feature points of each layer of grids according to the above method, it is necessary to select feature points with relatively uniform information from the extracted feature points. The specific steps are as follows: (1) Pyramidize the input image and calculate the number of feature points required for all pyramids. ; (2) Divide each layer of the image pyramid into squares. , and calculate and sort the Hariss value of the feature points of each square according to the standard deviation formula. The calculation formula is as follows:
[0045]
[0046] In the formula, Representative The Harss value of feature points, Represents the number of feature points in the grid and sets a threshold , if the calculated value , then the values below If the number of Harss feature points extracted from the square is less than the expected value in each square of the image pyramid, then the number of feature points expected in each square is calculated. Extract the largest front in the grid. Feature points, in order to ensure the number of feature points extracted; (3) Scan Detect the squares in the layer whose feature points are not 0, and input the Harss value of the feature points in the scanned squares into the standard deviation formula, calculate the result, and sort the feature points corresponding to the result from large to small, let it be SortPF, and then compare it with the expected number of feature points in the current square. Compare, if less than , then extract all feature points in SortPF and put them into the feature point set. If it is greater than , then only extract the previous Item feature points to feature point set; (4) Expected number of feature points per layer If the difference is greater than 0, the first In addition to the feature points in the feature point set, the feature points in the layer are sorted according to the size of the standard deviation, and the feature points with the same difference value are inserted into the feature point set from large to small. If the difference value is less than 0, the feature point set is directly stored in the final feature point set; (5) If ,set up , jump to step (2) and repeat the steps until Terminate the loop.
