Tragedies Involving Objects Thrown From High Places Are Frequent. AI Monitoring System: Let Me Protect You
Objects thrown from high places is a major problem in modern society, and there has always been a lack of effective monitoring methods. With the help of artificial intelligence technology, the security company uses video and image analysis to provide a solution for monitoring objects thrown from high places.
In recent years, there have been many reports of injuries caused by objects dropped or falling from high places. Water bottles, watermelon peels, cans, and even kitchen knives may suddenly fall from the sky and hit innocent passers-by. The minor injuries may even be fatal, making it difficult to prevent. The uncivilized behavior of dropping objects from high places is abhorrent.
However, in many cases,Because objects thrown from high places are sudden and occur at high speeds, and the images captured by surveillance cameras are not clear, it is often difficult for property management and police to find the perpetrators.
Now, many technology companies are using AI technology to solve this difficult social problem.
Tragedies involving objects thrown from high places occur frequently, and the culprits behind them are hard to track down
Throwing objects from high places has caused several social tragedies.
Last September, the first-instance verdict was delivered in the case of "a girl was killed by a falling iron ball from the sky", and objects thrown from high places once again attracted widespread attention from the society.
Four years ago, a fitness ball fell from the sky and hit a baby girl in a stroller on the head, causing her death. After that, the police investigated and visited many places, but the culprit was never found.
In September 2020, the court ruled that each household in the entire building (except for the homes that were actually uninhabited) should be compensated 3,000 yuan.
Although many owners are dissatisfied with the verdict, in this case, the only way to make such a verdict is to follow the provisions of the Civil Code since the perpetrator cannot be found.
Due to various reasons, such as difficulty in discovery, difficulty in collecting evidence, difficulty in holding people accountable, and low cost of breaking the law for perpetrators, throwing objects from high places has become one of the difficulties in community management. It is also called "the pain hanging over the city."
Objects thrown from high places have brought huge social harm, and even people have to be nervous when walking in their daily lives, which seriously affects people's sense of security and happiness.
Fortunately, with breakthroughs in AI technology in computing power and algorithms, objects thrown from high places will hopefully be effectively traced and curbed.
AI has developed a keen eye to automatically identify objects thrown from high altitudes
According to traditional investigation methods, once an object is thrown from a high place, it can only be checked by manual visits and reviewing surveillance videos. If the time of the object is uncertain, the staff needs to check the video frame by frame, which takes a lot of time.
To this end, the security field has launched AI solutions for tracing and alarming of objects thrown from high places.
AI image analysis, lock the parabolic point in one minute
In February this year, the small town of Leiden in Songjiang District, Shanghai, installed an AI monitoring system to ensure that people who throw objects from high places have nowhere to hide.
There are more than 80 high-rise buildings in the small town of Leiden, and objects thrown from high places has become a common complaint received by property staff, but investigations often yield no results.
The AI monitoring system can automatically identify objects being thrown from high places by analyzing images captured by surveillance cameras, and clearly record the trajectory of the objects falling. It can also send alarm images to property staff through the cloud platform as soon as possible.
The property staff can identify the window where the object was thrown in one minute by combining the alarm image and the surveillance video of the same period.So as to carry out door-to-door missionary work.
In addition, because the AI monitoring system records photos of the throwing behavior, the evidence is solid and residents will no longer refuse to admit it.
Automatically identify pet dogs and warn of dogs walking without a leash
In addition to objects thrown from high places, the intelligent monitoring system can also detect the phenomenon of dogs walking without a leash in the community.
When the camera captures a dog walking without a leash, the system will send an alarm message to the property management, alerting the public that a pet dog appears in the community square.After the property staff checks the surveillance video and confirms that the dog walker is not on a leash, they can find the dog walker and persuade him based on the activity trajectory captured by the system.
In addition to dropping objects from high places and walking dogs without a leash, the system will also automatically detect and alert uncivilized behaviors such as littering of household garbage and encroaching on fire passages, as well as actions that pose safety hazards, thereby improving the work efficiency of community managers. Previously, these behaviors could only be discovered by manual patrols.
Major technology companies release AI security tricks
The monitoring of objects dropped from high altitudes is very sensitive to the harsh environment and complex background, such as haze, rain and snow, strong light and insufficient lighting at night, because the target objects are generally small and fast.
In response to these problems, major technology companies have proposed corresponding solutions. For example, cameras that support fog-penetrating functions can still obtain high-definition videos and key details even in weather conditions with severe pollution and reduced visibility, which is called strong evidence for tracing.
Hikvision: Two smart cameras are responsible for the security of a building
Hikvision has launched an intelligent alarm solution for high-altitude dropping of objects. It only requires two smart cameras to detect and issue intelligent alarms for high-altitude dropping of objects on a facade.
Due to the high speed of objects thrown from high altitudes, it is difficult for ordinary cameras to capture a clear trajectory of the objects.To this end, Hikvision uses a dedicated high-altitude parabola camera (800W ultra-clear starlight camera) to capture high-definition images over long distances.
Through the switch, the signal is stably transmitted to the back-end recorder to realize monitoring preview, storage, review and other functions, so as to trace back the possible damage to ground vehicles, personnel, public property, etc.
Uniview Technologies: Clear visibility at night and in thunderstorms
Uniview Technologies has also developed a plan to prevent objects from being thrown from high places for the Yuhang community in Hangzhou.
For outdoor thunderstorms and insufficient light at night,Uniview Technologies has launched Super Starlight technology, which can display clear color images even without any external auxiliary light source.
In terms of data processing, in order to meet the needs of users for post-investigation and evidence collection, the clear video images obtained by its front-end equipment are stored in the back-end big data or command center platform. The platform supports the search, playback, and intelligent analysis of video data, thereby improving the efficiency of relevant staff.
Huawei: Using intelligent algorithms to filter out interference factors
Huawei's "Wanliyan" intelligent high-altitude object throwing solution is embedded with multiple intelligent algorithms, including the Huawei HoloSens SDC algorithm.
Through its independently developed ConvFilter noise reduction technology, ITSR detection technology and intelligent anti-interference technology, it can effectively filter out interference factors such as rain, snow, flying birds and insects, accurately detect falling objects from high altitudes, draw parabolic routes, and solve the problem of false alarms.
at present,Its intelligent tracing algorithm can achieve a detection rate of 95%.
Can technology + law protect "safety above our heads"?
Thanks to the above-mentioned artificial intelligence technologies and algorithms, community managers are able to effectively trace the source of events afterwards. These AI monitoring systems also have a certain deterrent effect on everyone, thereby enhancing residents' sense of security.
However, according to an industry insider, throwing objects from high places is an extremely niche scenario.There is almost no solution that can 100% identify all high-rise parabolic objects. Accurate identification of 90% and above is already excellent.
Therefore, while using the power of science and technology to curb these bad habits, it is more important to strengthen everyone's moral constraints and legal awareness.
On March 1 this year, the latest amendment to the Criminal Law came into effect, and "throwing objects from high places" was officially criminalized.
On the first day that the crime of dropping objects from a high place was implemented as an independent crime, the first case of dropping objects from a high place in the country was tried at the People's Court of Liyang City, Changzhou, Jiangsu Province.
The defendant Xu threw down two kitchen knives from the third floor.Although no personal injury or major property loss was caused, his behavior constituted the crime of throwing objects from a high place. In accordance with the Criminal Law, he was sentenced to six months in prison and fined 2,000 yuan.
Perhaps the technology still needs to be further improved, and the law cannot completely eliminate uncivilized behavior. But with the joint restraint and deterrence of the two, we can hopefully regain our "safety above our heads" soon.
