Indoor multi-camera intelligent linkage monitoring device based on depth sensing

The present invention belongs to an intelligent safety and guard technology, and especially relates to an indoor multi-camera intelligent linkage monitoring device based on depth sensing. The device comprises a collection module, a processing module and a communication module. The processing module comprises a switch, a server and monitoring system software. The monitoring system software completes the detection of abnormity invasion based on a depth image matching algorithm according to a three-dimensional point cloud image, performs structural abstraction of the obtained three-dimensional point cloud to complete the identification of the abnormity invasion, and finally transmits the collected video and images to a user terminal device to allow users to process abnormity invasion events. The intelligent linkage monitoring device can complete the passive monitoring for an invasion terminal to a user terminal and complete the active control from the user terminal to the invasion terminal. The indoor multi-camera intelligent linkage monitoring device based on the depth sensing is suitable for unattended operation indoor scene monitoring, has advantages of high invasion detection precision, low false alarm rate, monitoring without dead corners and can perform abnormal event early warning, etc.
