Problems solved by technology

[0003] However, the traditional network camera IPC can accurately detect the surrounding environment only when it is in a static state.
Once the IPC is cruising, no matter whether there is movement in the surrounding environment, it will send out an alarm signal. Users are often disturbed by false alarms, which is very inconvenient

Embodiment Construction

[0024] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, and the following embodiments do not constitute a limitation of the present invention.

[0025] This solution is aimed at IP cameras that support cruising (replaced by IPC in the following), such as the IPC of the external PTZ or the IPC of the dome camera. The preset position is the preset position of the IPC. When the IPC calls the preset position, the IPC will go to the preset position.

[0026] IPC cruise diagram, such as figure 1 Shown:

[0027] The cruise configuration is:

[0028] (1) The first preset position of IPC is preset position 1, stay for 3S (equivalent to t1);

[0029] (2) The second preset position of IPC is preset position 2, stay for 5S (equivalent to t2);

[0030] (3) The third preset position of IPC is preset position 3, stay for 4S (equivalent to t3);

[0031] After configuring cruise, start ...

Abstract

The invention discloses a method and device for detecting the motion during an IP camera cruising process. The method comprises the steps: the preset position and the corresponding staying time of an IP camera are initialized at first, the IP camera is started to cruise, when the IP camera moves to the preset position in the staying time, an image of the present frame is compared with an image of the previous frame, if the change of the image exceeds a set first threshold, the motion that is detected is determined, the detection of the motion is reported to make an alarm; when the IP camera moves between the preset position, the image of the present motion is cached, each time a image is cached, the image is compared with the corresponding frame image cached in the last cruising period, if the change of the image exceeds a set second threshold, the motion that is detected is determined, the detection of the motion is reported to make an alarm. The device provided by the invention comprises an initialization module, a staying time detection module and a motion time detection module. The method and the device provided by the invention improve the precision of the motion detection and reduce the misinformation.

Description

technical field [0001] The invention belongs to the technical field of video surveillance motion detection, and in particular relates to a motion detection method and device in cruising of a network camera. Background technique [0002] With the promotion and popularization of IP monitoring technology and intelligent technology, there are more and more application environments for video surveillance systems typical of shops, buildings, parks, etc. Motion detection, as a basic function in IPC, is used by more and more individuals and enterprises. use. [0003] However, the traditional network camera IPC can only perform accurate motion detection on the surrounding environment when it is in a static state. Once the IPC is cruising, no matter whether there is movement in the surrounding environment, it will send out an alarm signal. Users are often disturbed by false alarms, which is very inconvenient. Contents of the invention [0004] The object of the present invention i...
