System and method for capturing, storing, analyzing and displaying data related to the movements of objects
First Claim
1. A method operable on a computer that is coupled to a memory containing video data of a prescribed physical area, the method responsive to the movement of objects in the prescribed physical area, the method comprising:
- identifying objects in the prescribed physical area by querying the video data, wherein the objects that are identified are moving in the prescribed physical area;
generating a still image of the prescribed physical area;
specifying by a user, a virtual line in the prescribed physical area, wherein the virtual line is superimposed on a user-selected portion of the still image of the prescribed physical area;
determining a number of objects that cross the virtual line; and
superimposing a representation of the number of objects on the user-selected portion of the still image.

Abstract
A system and method for the capture and storage of data relating to the movements of objects, in a specified area and enables this data to be displayed in a graphically meaningful and useful manner. Video data is collected and video metadata is generated relating to objects (persons) appearing in the video data and their movements over time. The movements of the objects are then analyzed to detect the movements within a region of interest. This detection of movement allows a user, such as a manager of a store, to make informed decisions as to the infrastructure and operation of the store. One detection method relates to the number of people that are present in a region of interest for a specified time period. A second detection method relates to the number of people that remain or dwell in a particular area for a particular time period. A third detection method determines the flow of people and the direction they take within a region of interest. A fourth detection method relates to the number of people that enter a certain area by crossing a virtual line, a tripwire.

3. A method operable on a computer to detect and analyze movement of objects in a prescribed physical area, the method comprising:
-
receiving video data of the prescribed physical area from at least one camera; detecting movement of objects in the prescribed physical area generating video metadata in response to the detection act, the video metadata representing the detected objects and their movement in the prescribed physical area; storing the video metadata in a database; specifying by a user, a virtual line in the prescribed physical area, wherein the virtual line is superimposed on a user-selected portion of an image of the prescribed physical area; determining a number of detected objects that cross the virtual line; and generating a visually perceptible output of the number of detected objects, wherein the detected objects are superimposed on the user-selected portion of the image.

4. A system for detecting and analyzing movement of objects in a prescribed physical area, the system comprising:
-
an interface that receives video data of the prescribed physical area; a video management system coupled to the camera interface, the video management system storing the video data; a video analytics engine coupled to the video management system, the video analytics engine generating video metadata representing at least one object and its movement in the prescribed physical area; an object movement analytics engine coupled to the video analytics engine, the object movement analytics engine determining a number of object that cross a virtual line in the prescribed physical area; and a display coupled to the object movement analytics engine, the display displaying a visually perceptible output of the number of determined objects, wherein the virtual line and the visually perceptible output are superimposed on a user-selected portion of an image of the prescribed physical area.
