Method and Device for Video Surveillance

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a video surveillance method and device that improves detection of changes in the monitored environment by comparing data from two different background models: a short-term and a long-term model. The system analyzes pixel differences at specific time points to better identify unusual activities or movements in the surveillance area.

Use CasesContent extracted from patent full text and abstract with AI.

• Security monitoring in public and private spaces (e.g., airports, shopping centers, offices)
• Real-time detection of suspicious activities or intrusions
• Traffic surveillance for incident or accident detection
• Automated monitoring of restricted or sensitive areas
• Smart home security systems

BenefitsContent extracted from patent full text and abstract with AI.

• Enhanced accuracy in detecting unusual changes or activities by leveraging both short-term and long-term background models
• Reduced false alarms compared to traditional video surveillance methods
• Timely and reliable identification of security threats or anomalies
• Improved automated surveillance with less need for manual intervention

Patent Abstract

The invention relates to a method and a device for video surveillance, wherein by means of at least one video camera, an image of an image excerpt of an environment to be monitored in the vicinity of the video camera is recorded, wherein at least one pixel of a short-term background model assigned to the image excerpt is compared at a first point in time with a corresponding pixel of a long-term background model assigned to the image excerpt at the first point in time and with a corresponding pixel of the long-term background model at a second point in time, wherein the second point in time precedes the first point in time.
