I. Background introduction
With the acceleration of China’s urbanization process, a lot of high-rise buildings are rising, which brings about a serious problem of throwing objects from high altitude. As an uncivilized behavior in the city, the throwing behavior from high altitude has attracted much attention. At the same time, it brings great social harm (hidden danger of safety, property loss, damage to the environment, etc.). Because the uncivilized behavior of throwing objects from high altitude is mostly in the upper floors, the falling speed of the projectiles is very fast and the time of throwing objects is very short, and the throwing people are good at concealing the behavior of throwing objects, which makes it difficult for relevant departments to achieve effective evidence collection and accurate responsibility determination.
Second, demand analysis
There are still a variety of deficiencies in the high altitude parabolic prevention solutions on the market. It is in urgent need of an intelligent community high altitude parabolic AI intelligent identification system, which will change the traditional security monitoring from passive placement to active security, all-weather real-time monitoring and alarm; At the same time, the deep learning algorithm can quickly and accurately identify objects thrown at high altitude, trace the whole process of the occurrence of high altitude throwing behavior, and realize effective monitoring, evidence collection, accountability and management, which can further prevent and deter the uncivilized behavior of high altitude throwing, and effectively maintain and guarantee the “overhead safety” of people.
High altitude parabolic AI intelligent recognition system is to use the front end is equipped with hd camera or equipped with hd camera back to the surveillance video, the back-end video analysis instrument integrates machine vision, depth study of image processing, pattern recognition, measurement and related technologies such as video data obtained by means of monitoring the scene after the real-time deep understanding, automatically detect abnormal events in the scene with the police. For example, different applications such as motion detection, abnormal behavior prediction, out-of-bounds alarm, and aerial projectiles have different requirements for video surveillance, so video analysis algorithms should be tailored to their respective applications.
Through this program, we can effectively obtain the floor information of the parabolic and the overall record of the event of high altitude parabolic, and curb the occurrence of uncivilized behavior to a certain extent.
Iii. Scheme construction
In this scheme architecture, the high-altitude parabolic AI intelligent identification temperature control all-in-one machine mainly carries out algorithm analysis on the real-time video acquired and sends it back to the streaming media server software for real-time warning, real-time live broadcasting and video storage. The EasyCVR video streaming server software of TSINGSEE Gets the alarm information of the temperature control all-in-one intelligently recognized by the altitude throwing AI through the SDK for distribution and display.
4. Functional advantages
1. Convenient system deployment
Because EasyCVR is based on the mature and ubiquitous IP network to achieve system deployment, which brings a series of deployment convenience, simple and easy to use in operation, easy to deal with in the later maintenance, and if the latter need to be extended, can also be expanded without changing the original architecture.
2. Daily video monitoring and review
As an active real-time video system, EasyCVR can perform 24-hour real-time video monitoring and operation management on the real-time situation of each monitoring site within the monitoring range without human intervention. The throwing process is recorded, and the event has evidence to follow. All floors are covered. The accident process of property damage, casualties and other accidents caused by uncivilized behavior of throwing sundry objects at high altitude is effectively recorded, which is convenient for checking the whole throwing process later.
3. System inspection
It can automatically inspect all cameras and network storage recorders (network status, storage status, video status, channel status, etc.), and send signals to the platform to detect the normal or fault of the system, and give alarm reminders.
4. Ultra hd image capture
Support 4K ultra high definition starlight camera, high-level picture quality display clearer, clearer details.
5. Movement detection
The movement detection function is used to protect and detect sensitive areas. Once the monitoring area is changed, an immediate alarm is generated. Each monitoring image can be divided into several small rectangular areas, and any one or more of them can be selected for mobile detection and analysis. Once the image changes in the set detection area, the alarm will be triggered.
