Description

Technical Field

[0001] This application relates to the technical field of monitoring, and in particular to a method and system for monitoring objects thrown from heights. Background Technology

[0002] With the continuous development of cities, some uncivilized residents of high-rise buildings throw garbage bags and wine bottles at will during the day or night, which can easily cause pedestrians to be injured by falling objects. Therefore, monitoring of objects thrown from high-rise buildings is quite necessary in community security monitoring.

[0003] Existing technologies also include some corresponding methods for monitoring objects thrown from heights. These methods use multiple cameras to comprehensively monitor the windows of each unit building in the community in real time and acquire image data. Then, the target is analyzed and processed to identify moving targets in the image data. Based on the tracking of the moving targets, the trajectory of the target and the location where it was thrown are obtained. However, this monitoring method requires multiple cameras, which need to be turned on 24 hours a day, resulting in a significant reduction in the lifespan of the cameras and excessively high monitoring costs. This situation needs further improvement. Summary of the Invention

[0004] To address the high monitoring costs of existing methods for detecting objects thrown from heights, this application provides a method and system for detecting objects thrown from heights, employing the following technical solution:

[0005] In a first aspect, this application provides a method for detecting objects thrown from heights, applied to a high-altitude object-throwing monitoring system. The system includes a controller, multiple evenly distributed monitoring cameras, a road surface infrared sensor, floor infrared sensors, and an alarm. The monitoring range boundaries of adjacent monitoring cameras are connected or overlap. A road surface infrared sensor is installed at the point of connection or overlap. The controller connects and controls the road surface infrared sensor, floor infrared sensor, monitoring cameras, and alarm. The method includes the following steps:

[0006] The road infrared sensors and monitoring cameras are numbered and grouped accordingly. The road infrared camera and its adjacent multiple monitoring cameras form a group, and the road infrared sensor is located in the middle of the monitoring cameras in the same group.

[0007] Upon receiving a pedestrian pass detected by the first road surface infrared sensor, control the monitoring camera corresponding to the first road surface infrared sensor to turn on and capture video of the window area of ​​the unit building.

[0008] If any of the aforementioned road infrared sensors detects a pedestrian passing by, and the floor infrared sensor detects an object falling, the alarm will be activated.

[0009] In a case that the second road infrared sensor detects a pedestrian passing, the first road infrared sensor corresponding monitoring camera is closed, and the second road infrared sensor corresponding monitoring camera is opened, wherein the second road infrared sensor is adjacent to the first road infrared sensor.

[0010] By adopting the above technical scheme, the main purpose of monitoring high-altitude throwing is to prevent pedestrians from being injured by high-altitude throwing objects. The application detects whether a pedestrian passes through by using a road infrared sensor, and then detects whether an object falls by using a floor infrared sensor. When a pedestrian passes through and an object is detected to fall, an alarm is sounded. When the road infrared sensor detects a pedestrian passing through, the road infrared sensor corresponding monitoring camera is controlled to be opened and a unit building window area video is shot. If a high-altitude throwing object causes injury, the thrower can be found through the shot unit building window area video, so that the thrower bears certain responsibility. Even if no high-altitude throwing object causes injury, if a pedestrian passes through when a high-altitude throwing object is thrown, the thrower can also be found according to the shot unit building window area video, and is criticized and educated. In addition, the application controls the corresponding monitoring camera to be opened only when a pedestrian passes through, so as to avoid the case that the monitoring camera is always opened, resulting in high monitoring cost.

[0011] Optionally, the road infrared sensor and at least four monitoring cameras adjacent thereto form a group, and the road infrared sensor is located at a middle position of the four monitoring cameras.

[0012] By adopting the above technical scheme, the road infrared sensor and at least four monitoring cameras adjacent thereto form a group, and the road infrared sensor is located at a middle position of the four monitoring cameras. When a pedestrian is detected by the road infrared sensor, no matter in which direction the pedestrian moves or stays in the original position, the surrounding monitoring cameras can monitor the high-altitude throwing object above. When another pedestrian passes through the adjacent second road infrared sensor, the monitoring camera corresponding to the first road infrared sensor is closed, but the monitoring camera corresponding to the second road infrared sensor can still monitor the high-altitude throwing object above the first road infrared sensor.

[0013] Optionally, the method further comprises:

[0014] In a case that the high-altitude throwing object is determined, the unit building window area video is analyzed to obtain a throwing window.

[0015] Resident information is obtained based on the throwing window.

[0016] A throwing segment is intercepted, and the throwing segment and safety prompt information are pushed to the resident.

[0017] By adopting the technical scheme, in the case of high-altitude throwing, the unit building window area video is analyzed to obtain a throwing window, and then the information of the resident is obtained based on the throwing window, so that the resident can be found and the corresponding responsibility can be borne, and the throwing segment is intercepted and the safety prompt information is pushed to the resident for safety education.

[0018] Optionally, the method further comprises:

[0019] In the case of high-altitude throwing, the target number of the monitoring camera corresponding to the unit building window area video corresponding to the high-altitude throwing is recorded;

[0020] The monitoring camera with the target number is controlled to keep an open state.

[0021] By adopting the technical scheme, the monitoring camera is numbered, when the high-altitude throwing occurs, the target number of the monitoring camera corresponding to the unit building window area video corresponding to the high-altitude throwing is recorded, and then the monitoring camera with the target number is kept in an open state, so that the resident window with the high-altitude throwing behavior before can be more fully monitored.

[0022] Optionally, the method further comprises:

[0023] In the case that the high-altitude throwing is not monitored for a continuous preset time, the target number record is deleted.

[0024] By adopting the technical scheme, in the case that the high-altitude throwing is not monitored for a continuous preset time, the target number record is deleted, so that the corresponding monitoring camera is not kept in an open state all the time, so as to save the power cost.

[0025] Optionally, when the floor infrared sensor senses that there is a living body outside the window, all the monitoring cameras are controlled to be turned on and send warning information.

[0026] By adopting the technical scheme, when the floor infrared sensor senses that there is a living body outside the window, all the monitoring cameras are controlled to be turned on and send warning information, so as to intervene in time when there is a high-altitude falling risk.

[0027] In a second aspect, the application provides a high-altitude throwing detection system, which comprises a controller, a plurality of uniformly distributed monitoring cameras, a road infrared sensor, a floor infrared sensor and an alarm, the monitoring ranges of two adjacent monitoring cameras are connected or overlapped, the road infrared sensor is arranged at the connected or overlapped place, the controller is connected to control the road infrared sensor, the floor infrared sensor, the monitoring camera and the alarm, and the system comprises:

[0029] The start shooting control module is used for starting and shooting the unit building window area video by the monitoring camera corresponding to the first road infrared sensor when the first road infrared sensor senses the passing of the pedestrian.

[0030] The alarm module is used for controlling the alarm to give an alarm when the building infrared sensor senses the falling of the article.

[0031] The switching module is used for closing the monitoring camera corresponding to the first road infrared sensor and starting the monitoring camera corresponding to the second road infrared sensor when the second road infrared camera senses the passing of the pedestrian.

Thus, the features defined with "first", "second", "third", "fourth", "fifth", "sixth", "seventh" and "eighth" can explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, the meaning of "a plurality of" is two or more, unless otherwise specified.

[0046] High-altitude throwing events often cause pedestrians to be injured, so it is necessary to monitor high-altitude throwing in community security monitoring.

[0047] In the related art, multiple cameras are used to comprehensively and real-time monitor the windows of each unit building of the community and obtain image data, and then the position of the throwing is determined. This monitoring method requires multiple cameras and needs to be turned on for 24 hours, which greatly reduces the service life of the camera and results in high monitoring cost. The present application provides a high-altitude throwing monitoring method and system, which monitors whether there is throwing through the floor infrared sensor, then sends an alarm, and monitors whether there is a pedestrian passing through through the road infrared sensor. When a pedestrian passes through, the corresponding monitoring camera of the road infrared sensor is turned on and the unit building window area video is shot, so that when a high-altitude throwing person appears, the thrower can be found through the shot unit building window area video, and the present application only controls the corresponding monitoring camera to be turned on when a pedestrian passes through, avoiding the situation that the monitoring camera is always turned on, resulting in high monitoring cost.

[0048] Reference Figure 1 An application scenario diagram of a high-altitude throwing monitoring method according to an embodiment of the present application.

[0049] A high-altitude throwing monitoring method applied in a high-altitude throwing monitoring system, the system comprising a controller, a plurality of uniformly distributed monitoring cameras, a road infrared sensor, a floor infrared sensor and an alarm, the monitoring ranges of two adjacent monitoring cameras are connected or overlapped, the road infrared sensor is arranged at the connected or overlapped position, and the controller is connected to control the road infrared sensor, the floor infrared sensor, the monitoring camera and the alarm.

[0050] Reference Figure 2 An example flowchart of a high-altitude throwing monitoring method according to an embodiment of the present application.

[0051] S110, numbering the road infrared sensor and the monitoring camera, and grouping the road infrared sensor and the monitoring camera correspondingly.

[0052] The road surface infrared camera and the plurality of adjacent monitoring cameras form a group, and the road surface infrared sensor is located at the middle position of the monitoring cameras in the same group. Specifically, in the embodiment, the road surface infrared sensor and the four adjacent monitoring cameras form a group, and the road surface infrared sensor is located at the middle position of the four monitoring cameras. By corresponding grouping of the road surface infrared sensor and the monitoring camera, when the specific road surface infrared sensor senses a signal that a pedestrian passes, a part of the monitoring camera can be controlled to take a picture, and the other cameras remain in standby state, so as to save the power cost.

[0053] S120, in the case that the first road surface infrared sensor senses that a pedestrian passes, the monitoring camera corresponding to the first road surface infrared sensor is controlled to start and take a unit building window area video.

[0054] The monitoring camera is upwardly directed to take a picture of the unit building window area, thereby monitoring the behavior of high-altitude throwing.

[0055] S130, in the case that any road surface infrared sensor senses that a pedestrian passes, when the floor infrared sensor senses that an article falls, the alarm is controlled to give an alarm.

[0056] When there is no pedestrian passing, the alarm does not give an alarm, thereby preventing the rest of the residents from being disturbed at night or during the day. When there is a pedestrian passing, when the floor infrared sensor senses that an article falls, the alarm is controlled to give an alarm, so as to remind the passing pedestrian to pay attention to high-altitude throwing.

[0057] S140, in the case that the second road surface infrared camera senses that a pedestrian passes, the monitoring camera corresponding to the first road surface infrared sensor is closed, and the monitoring camera corresponding to the second road surface infrared sensor is started.

[0058] The second road surface infrared sensor is adjacent to the first road surface infrared sensor. When a pedestrian passes the first road surface infrared sensor, the monitoring camera corresponding to the first road surface infrared sensor is always kept in the starting state, and is only closed when the adjacent infrared sensor detects the pedestrian. Thus, when a new pedestrian walks on the road surface, the monitoring camera behind will be closed in turn, thereby saving the power cost.

[0059] And, since the road surface infrared sensor and its adjacent at least four monitoring cameras are a group, the road surface infrared sensor is located in the middle position of the four monitoring cameras, then when the pedestrian is detected by the road surface infrared sensor, no matter which direction the pedestrian moves or stays in place, the surrounding monitoring cameras can monitor the high-altitude throwing situation above; and when another pedestrian passes through the adjacent second road surface infrared sensor, the monitoring camera corresponding to the first road surface infrared sensor will be turned off, but at this time the monitoring camera corresponding to the second road surface infrared sensor can still monitor the high-altitude throwing situation above the first road surface infrared sensor, thereby reducing the occurrence of monitoring failure when multiple people walk through the road.

[0060] In some optional embodiments, when the monitoring camera captures the high-altitude throwing behavior, the thrower can be found through the unit building window area video to criticize and educate him, or make him bear the corresponding responsibility when the high-altitude throwing injures people.

[0061] Referring to Figure 3 For another exemplary flowchart of a high-altitude throwing monitoring method according to an embodiment of the present application.

[0062] The method further comprises:

[0063] S150, in the case of determining high-altitude throwing, analyzing the throwing of the unit building window area video to obtain a throwing window;

[0064] S160, obtaining the resident information based on the throwing window;

[0065] Wherein, the house number can be determined according to the unit building, floor and position of the throwing window, and then the corresponding resident information is obtained.

[0066] S170, intercepting the throwing segment and pushing the safety prompt information to the resident.

[0067] The present application intercepts the throwing segment and pushes the throwing segment and safety prompt information to the resident for warning and education.

[0068] In the above embodiment, whether a pedestrian passes through is detected by the road infrared sensor, and whether an article falls is detected by the floor infrared sensor, and when it is detected that an article falls, an alarm is sounded by the alarm; and when the road infrared sensor detects that a pedestrian passes through, the monitoring camera corresponding to the road infrared sensor is controlled to be turned on and the unit building window area video is shot, if a high-altitude throwing object injures a person, the thrower can be found through the shot unit building window area video, so that the thrower bears certain responsibility, and even if there is no high-altitude throwing object that injures a person, if a pedestrian passes by when a high-altitude throwing object is thrown, the thrower can also be found according to the shot unit building window area video for criticism and education; in addition, the corresponding monitoring camera is controlled to be turned on only when a pedestrian passes through, so as to avoid the case that the monitoring cost is too high due to the fact that the monitoring camera is always turned on.

[0069] In some other embodiments, the unit building window area where a high-altitude throwing object occurs can be more closely monitored.

[0070] Reference Figure 4 For another exemplary flowchart of a high-altitude throwing object monitoring method in the embodiments of the present application.

[0071] S180, in a case where it is determined that there is a high-altitude throwing object, recording a target number of a monitoring camera corresponding to a unit building window area video of the high-altitude throwing object.

[0072] S190, controlling the monitoring camera with the target number to always remain in an on state.

[0073] Each monitoring camera has a number, and when a high-altitude throwing object occurs in the unit building window area corresponding to the monitoring camera, the number is recorded, and then the monitoring camera with the number is controlled to always remain in an on state for close monitoring.

[0074] S200, in a case where no high-altitude throwing object is monitored for a continuous preset time, deleting the target number record.

[0075] The continuous preset time can be 2 months, and when no high-altitude throwing object is monitored for 2 months, the number record is deleted, so that the corresponding monitoring camera does not always remain in an on state, so as to save power cost. When a high-altitude throwing object occurs again within 2 months, the timing is restarted.

[0076] Optionally, in some embodiments, when a living body is outside a window, there is a risk of falling of the living body, and timely intervention is needed.

[0077] S210, when the floor infrared sensor senses that a living body is outside a window, controlling all monitoring cameras to be turned on and sending a warning information.

[0078] The pre-warning information can be sending a help-seeking information to a cell management platform or a specific contact phone, or can be sending a pre-warning information to a resident or other owners near the resident after analyzing the resident information corresponding to the window through the image collected by the monitoring camera.
