With the continuous development of computer technology, computer vision has become an important emerging technology, which involves many aspects of technology such as image processing, pattern recognition, and machine learning. Combining the technical advantages of computer vision and the advantages of cloud computing, it has become possible to implement a cloud video surveillance system based on computer vision, and the Java language has significant advantages in developing cloud applications. This article will introduce the implementation of a cloud-based video surveillance system based on Java. Logical process of computer vision-based cloud video surveillance system.
1. Environment preparation
1. Computer vision library
OpenCV is a powerful open source computer vision library that can handle various image and video processing tasks, including object recognition , tracking, 3D reconstruction, image segmentation, etc. Java uses the OpenCV library with the Java language through JavaCV.
2. Cloud storage platform
Cloud storage is a large-scale distributed storage technology. Using cloud storage, data can be stored in the cloud to avoid data loss and data security issues, and it is also convenient Enable data sharing and collaborative work. Common cloud storage platforms include Alibaba Cloud, Tencent Cloud, etc.
3. Camera
Choose a high-resolution camera to get clearer video images. Combining it with the OpenCV library has very good results.
2. Java implementation process
1. Video stream collection
Use JavaCV to obtain real-time video stream, which can be opened and received in a Java application to receive audio and video from the web camera Stream or the audio and video stream of a local camera, and store the video frames in the memory as input for subsequent image processing.
2. Image processing algorithm
Select the corresponding image processing algorithm for specific application scenarios. For example, target detection algorithms are used in object tracking and target positioning, and edge detection algorithms are often used in contour recognition, etc. Various image processing algorithms can be implemented using OpenCV functions.
3. Data storage in the cloud
Store the processed video data in the cloud to realize cloud data sharing and storage. At the same time, storing data in the cloud can also avoid data loss and improve data security. sex.
4. Provide Web services
Use Java Web framework for development, provide video surveillance Web services, and realize cloud video surveillance functions. Java Web frameworks include Spring, Struts, MyBatis, etc. You can develop quickly by choosing the appropriate framework.
5. Realize remote control
Provide a Web interface or APP to remotely control the cloud video surveillance system, such as turning on and off cameras, adjusting image quality, etc. Java web applications can use protocols such as WebSocket or HTTP for real-time interaction.
3. Benefits of realizing cloud video surveillance system
1. Remote control
Through the cloud video surveillance system, you can easily control the camera remotely, such as turning on and off the camera, Adjust camera position, adjust image quality, etc.
2. Data security
Through cloud storage, data loss can be avoided and the security of video data can be protected.
3. Facilitate data collaboration
Through cloud storage, multiple users can easily collaborate and share data.
This article introduces the development logic process of a cloud video surveillance system based on computer vision and cloud computing technology. It uses Java to realize camera video stream collection, image processing algorithms, cloud data storage and other functions, and finally realizes remote Monitoring and collaborative working capabilities. This kind of technological innovation has had an important impact on future scientific and technological development and social life.
The above is the detailed content of Java implements the logical process of a cloud video surveillance system based on computer vision. For more information, please follow other related articles on the PHP Chinese website!
