Problems solved by technology
However, there are still deficiencies that it is only suitable for vehicle tracking in scenarios where multiple cameras have overlapping areas. In practical applications, especially in large-scale monitoring scenarios, it is impossible to achieve such a dense distribution of cameras, and for tracking other moving objects, For example, in the tracking of people, there may be switching between indoor and outdoor scenes, but the system and method of the invention cannot complete relay tracking

[0052] The video acquisition module in the wireless smart terminal is used to collect and temporarily store real-time video. First, the intelligent processing module determines suspicious targets. The rules for determining suspicious targets are selected and set according to the monitoring purpose at the initial stage of system construction. Example 1, the intelligent monitoring system is designed to monitor whether there are personnel violence incidents in public places, so when there is a fight between people in the monitoring area, all the people involved in the fight are identified as suspicious targets. Example 2, the intelligent monitoring system is designed to monitor whether the vehicle crosses the boundary and violates the rules. Once the vehicle crosses the boundary, it will be determined as a suspicious target. The method of determining the suspicious target is: the intelligent processing module extracts the outline of the moving human body by combining the backgroun...

The invention discloses a wireless intelligent monitoring device and a wireless intelligent monitoring method based on machine to machine (M2M) communication. The device comprises a monitoring station and a wireless monitoring terminal, wherein the monitoring station consists of a server personal computer (PC), an intelligent management module and a wireless communication module; and the wireless monitoring terminal consists of a video acquisition module, an intelligent processing module and a wireless communication module. The method comprises the following steps that: (1) the monitoring station transmits topology information; (2) the wireless monitoring terminal receives the topology information; (3) the intelligent processing module in the terminal estimates a relay point; (4) the terminal broadcasts a relay task; (5) the monitoring station judges whether tracking is continued; (6) the relay point performs feature matching; (7) the relay point judges whether an object is tracked for relaying; (8) the relay point tracks the object, and estimates the next relay point; (9) a relay point terminal waits for a new task; and (10) the monitoring station judges whether alarm is performed. The device and the method are applied to the joint monitoring of a plurality of complex scenes indoors or outdoors without the limit of distance, so that a monitoring system is reliable, and communication cost is saved simultaneously.
Description
technical field [0001] The present invention belongs to the field of electronic information technology, and further relates to a wireless intelligent monitoring device and method based on machine-to-machine (Machine To Machine, M2M) communication in the field of wireless communication and computer vision. [0002] The invention utilizes the M2M wireless communication and video intelligent analysis device and method to realize behavior analysis and relay tracking of moving targets in a large-scale monitoring system. Background technique [0003] At present, monitoring systems have been widely used in all walks of life. In these monitoring systems, cameras or cameras are mostly used for video recording, and the video is transmitted to the monitoring center in a wired manner for analysis and storage. This requires a lot of manpower and material resources. Moreover, suspicious targets and behaviors cannot be discovered in time. However, if wireless video transmission is used, i...
