[0001] The present invention relates to the technical field of park intelligent management and control, and in particular to a smart park management method based on an Internet of Things platform. Background Art

[0002] There are usually multiple indoor places distributed inside the office park, and relevant personnel work in different indoor places. In order to ensure the normal operation of the indoor places, multiple cameras are usually installed inside the indoor places. The cameras installed in different positions can comprehensively shoot the indoor places, and then the back-end management personnel can view the images shot by the cameras in real time to determine whether there are any abnormalities in the indoor places. Although the above method can monitor the indoor places in the park in real time, there will inevitably be a certain time lag and monitoring omissions through manual viewing. In addition, the use of a single camera monitoring method and ensuring comprehensive and reliable monitoring of indoor places reduces the efficiency and reliability of the management of the park's indoor places.

[0025] Step S103, using the following formula (3), according to the current shooting focal length of each multi-angle camera, select a multi-angle camera from all multi-angle cameras as the main camera,

[0026]

[0027] In the above formula (3), G represents a selection value corresponding to selecting a multi-angle camera from all multi-angle cameras as the main camera, that is, when G has a maximum value, the multi-angle camera on one of the XOY plane, XOZ plane, and YOZ plane is used as the main camera.

[0059] Preferably, in step S1, it also includes:

[0060] The IoT platform extracts the relative distance between the person and the target object in the indoor place from the infrared detection data, and determines whether the relative distance has changed; at the same time, it constructs a three-dimensional space coordinate system for the indoor place, with the upper right vertex inside the indoor place as the origin, the horizontal forward direction as the positive direction of the X axis, the horizontal right direction as the positive direction of the Y axis, and the vertical downward direction as the positive direction of the Z axis.

[0071] The beneficial effects of the above technical solution are as follows: using the above formula (1), according to the position coordinates of the infrared sensor corresponding to the change in relative distance in the indoor place, the shooting position points corresponding to all multi-angle cameras in the indoor place are determined, so as to intelligently select the optimal monitoring position for monitoring, which is convenient for equipment management, improves the safety factor of the park, and reduces the occurrence of abnormal events; then using the above formula (2), according to the shooting position points corresponding to all multi-angle cameras in the indoor place and the position coordinates of the infrared sensor corresponding to the change in relative distance in the indoor place, the current shooting focal length of each multi-angle camera is determined, so that all the changed positions in the place can be photographed, ensuring full coverage of automatic monitoring of the changes, effectively saving human supervision costs, and realizing intelligent management; finally, using the above formula (3), according to the current shooting focal length of each multi-angle camera, a multi-angle camera is selected from all multi-angle cameras as the main camera, and then a multi-angle camera with clearer illumination and more shooting changes is selected as the main monitoring, which is convenient for single analysis of the main camera and will not cause confusion in data analysis.

[0072] Preferably, in step S2, analyzing and processing the infrared search data to determine the relative position relationship between the person in the indoor place and the target object; judging whether the person has entered the monitoring range according to the relative position relationship; and marking the corresponding person in the captured image data according to the above judgment result specifically includes:

[0073] The relative distance between the person in the indoor place and the target object is extracted from the infrared detection data through the Internet of Things platform, and the relative distance is compared with a preset distance threshold; if the relative distance is less than or equal to the preset distance threshold, it is determined that the person has entered the monitoring range; if the relative distance is greater than the preset distance threshold, it is determined that the person has not entered the monitoring range;

[0074] If it is determined that the person has entered the monitoring range, the edge contour information of the corresponding person is determined from the image frame corresponding to the captured image data, so as to mark the corresponding person.

[0075] The beneficial effect of the above technical solution is: through the above method, since each target object in the indoor place is correspondingly provided with an infrared sensor, the corresponding monitoring range is delineated with each target object as the center and the preset distance threshold as the radius. Only when a person enters the monitoring range, the edge contour information of the corresponding person is determined from the image picture corresponding to the captured image data, so as to further mark the person on the image picture, so as to facilitate the subsequent accurate identification of the behavior of the person entering the monitoring range.

[0079] Preferably, in step S3, judging whether a safety-related event occurs to the marked person according to the real-time action behavior information specifically includes:

[0080] The body movement posture of the marked person is compared with a preset body movement database. If the body movement posture exists in the preset body movement database, it is determined that a safety-related incident has occurred to the marked person; otherwise, it is determined that no safety-related incident has occurred to the marked person.

[0081] The beneficial effect of the above technical solution is: through the above method, it is possible to quantitatively determine whether a safety-related incident occurs to the marked person; wherein, the preset body movement database contains a variety of body movements associated with different safety-related accidents, and the safety-related accidents may include climbing falls, etc.

[0082] Preferably, in step S4, if a security-related incident occurs to the marked person, RFID recognition or ORC text recognition is performed on the certificate held by the marked person; and according to the result of the recognition, triggering an alarm action in the indoor place through the Internet of Things platform specifically includes:

[0083] If a security-related incident occurs to the tagged person, the RFID induction recognition or ORC text recognition is performed on the certificate held by the tagged person to obtain the RFID induction information of the certificate or the text information on the surface of the certificate;

[0084] According to the RFID sensing information or the text information, the identity information of the marked person is determined to judge whether the marked person is a person prohibited from entering the indoor place; if so, the alarm device inside the indoor place is instructed to sound an alarm through the Internet of Things platform.

[0085] The beneficial effect of the above technical solution is: through the above method, when it is determined that a security-related incident occurs to the marked person, the identity information of the marked person can be further verified, so as to determine whether there is an illegal intrusion into the indoor place, and adaptive sound alarm can be performed to achieve timely and comprehensive safety management of the indoor place.
