Abstract
A system and method for operator-side privacy zone masking of surveillance is provided. The system includes a video surveillance camera equipped with a coordinate engine for determining coordinates of a current field of view of the surveillance camera; and a frame encoder for embedding the determined coordinates with video frames of the current field of view. The system also includes a privacy zone information database for storing coordinates of predefined privacy zones; and a video viewing unit for viewing stored video frames. The video viewing unit is in communication with the frame storage unit and the privacy zone information database.
Claims15
A video surveillance system comprising:
- a frame storage unit for receiving and storing video frames;
- a surveillance camera in communication with said frame storage unit, said surveillance camera having:
- a coordinate engine for determining coordinates of a current field of view of said surveillance camera;
- and
- a frame encoder for embedding the determined coordinates with video frames of said current field of view;
- a privacy zone information database for storing coordinates of predefined privacy zones;
- and
- a video viewing unit for viewing stored video frames, said video viewing unit being in communication with said frame storage unit and said privacy zone information database, said video viewing unit including:
- a mask generator for receiving said stored coordinates of said predefined privacy zones and generating a mask for said predefined privacy zones located within a field of view of a currently requested video frame of said stored video frames;
- a render engine for combining said generated masks with said currently requested video frame to obscure regions of said video frame corresponding to said predefined privacy zones;
- and
- a view port for displaying said masked video frames.
A method for privacy masking, comprising:
- imaging a security zone and generating video frames of said security zone;
- determining coordinates of said imaged security zone;
- embedding said coordinates of said imaged security zone in said video frames;
- storing said video frames with said embedded coordinates;
- retrieving said video frames for viewing by an operator;
- receiving privacy zone coordinates pre-stored in a privacy zone information database;
- identifying privacy zones within said imaged security zone based on said retrieved privacy zone coordinates;
- generating one or more masks corresponding to said privacy zones within said imaged security zone;
- and
- overlaying said generated masks onto said identified privacy zones at a operator-side viewing station during viewing of said video frames.
A computer readable medium embodying instructions for controlling one or more processors to perform a method of operator-side privacy masking of surveillance video, said method comprising:
- controlling a video surveillance camera to image a security zone;
- generating video frames of said security zone by said video surveillance camera;
- determining coordinates of said imaged security zone;
- embedding by said video surveillance camera said coordinates of said imaged security zone in said video frames;
- retrieving privacy zone coordinates prestored in a privacy zone information database;
- identifying privacy zones within said imaged security zone based on said retrieved privacy zone coordinates;
- generating one or more masks corresponding to said privacy zones within said imaged security zone;
- and
- overlaying said generated masks onto said identified privacy zones at a operator-side viewing station during viewing of said video frames.
