The invention discloses an image acquisition device and a method for detecting occlusion of human face and facial features. The method comprises: step 1: using the image acquisition device to collect video images of a monitoring area; step 2: using the image acquisition device to collect video images Carry out background modeling and detect foreground, and judge that there is the appearance of human face in described video image; Step 3: When detecting that human face appears in described video image, detect whether there is occlusion in described image acquisition equipment, when judging When occlusion occurs, start an alarm prompt. When it is judged that there is no occlusion, go to step 4; step 4: continue to detect the occlusion of the face and facial features, that is, face integrity detection, and judge whether there is a person in the image acquisition device based on this Face occlusion. The method of the invention has good real-time performance and high detection accuracy, provides automatic and intelligent monitoring means for the bank's automatic teller machine system, and provides technical support for the management mode of the bank's unattended operation.
Description
technical field [0001] The invention relates to the field of video monitoring, in particular to an image acquisition device and a detection method for occlusion of human face and facial features. Background technique [0002] In recent years, the crime of automatic teller machines has shown a high incidence. Criminal activities such as masked disguise and malicious blocking of the camera have occurred from time to time, which seriously endangers the normal financial management order. Public security issues based on automatic teller machines have received more and more attention. attention. However, the traditional monitoring mode adopts the method of "only recording but not judging". It can only investigate and round up the abnormal situation through video playback after the incident, and it is impossible to judge and alarm in real time. Therefore, abnormal occlusion detection based on surveillance video can realize automatic detection and alarm of abnormal behavior in the ...
