Directional object detection
First Claim
1. A method of monitoring whether an object of interest is passing through an area within a field of view of a scene observed by a video camera, the method comprising:
- receiving video data representing the field of view of the scene observed by the video camera;
using video analytics to track an object of interest represented in the video data;
configuring a detection zone within the area, the detection zone having at least two sides;
signaling an occurrence of an event when the tracked object of interest is continually present in the detection zone during a period beginning when the tracked object of interest enters the detection zone on one side and ending when the tracked object of interest leaves the detection zone from a different side; and
determining a direction the tracked object of interest traveled through the detection zone by determining which side of the detection zone the tracked object of interest entered and which side of the detection zone the tracked object exited.

Abstract
Video analytics is used to track an object of interest represented in video data representing the field of view of a scene observed by a video camera. A multidimensional virtual beam is used to detect whether the tracked object of interest is continually present in a detection zone within the field view of the scene. An occurrence of an event is signaled when the tracked object of interest is continually present in the detection zone during a period beginning when the tracked object of interest enters the detection zone and ending when the tracked object of interest leaves the detection zone through the opposite side, after having completely crossed through the detection zone. Use of a virtual beam detection zone reduces false alarms as compared to the numbers of incidences of false alarms of traditional detection methods, while adding several features and benefits.

-
receiving video data representing the field of view of the scene observed by the video camera; using video analytics to track an object of interest represented in the video data; configuring a detection zone within the area, the detection zone having at least two sides; signaling an occurrence of an event when the tracked object of interest is continually present in the detection zone during a period beginning when the tracked object of interest enters the detection zone on one side and ending when the tracked object of interest leaves the detection zone from a different side; and determining a direction the tracked object of interest traveled through the detection zone by determining which side of the detection zone the tracked object of interest entered and which side of the detection zone the tracked object exited. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A video surveillance system, comprising:
-
at least one video camera configured to monitor whether an object of interest is passing through a detection zone within a field of view of a scene observed by the at least one video; a computer system connected to the at least one video camera, and wherein the computer system further comprises; a memory; and a processor, wherein the memory comprises instructions, that when executed by the processor, cause the processor to; receive video data representing the field of view of the scene observed by the at least one video camera; track an object of interest represented in the video data using video analytics; configure the detection zone to include a first side and a second side positioned opposite to each other and thereby defining opposite sides of the detection zone; and signal an occurrence of an event when the tracked object of interest is continually present in the detection zone during a period beginning when the tracked object of interest enters the detection zone on the first side or the second side and ending when the tracked object of interest leaves the detection zone from the opposite side; and determining a direction the tracked object of interest traveled through the detection zone by determining which side of the detection zone the tracked object of interest entered and which side of the detection zone the tracked object of interest exited. - View Dependent Claims (31)

32. A non-transitory computer readable medium storing instruction, that when executed by a processor, cause the processor to perform the operations of:
-
receiving video data representing a field of view of a scene observed by a video camera; using video analytics to track an object represented in the video data; configuring a detection zone within the field of view including a first side and a second side positioned opposite to each other and thereby defining opposite sides of the detection zone; signaling an occurrence of an event when the tracked object is continually present in the detection zone during a period beginning when the tracked object enters the detection zone on the first side or the second side and ending when the tracked object leaves the detection zone from the opposite side; and determining a direction the tracked object traveled through the detection zone by determining which side of the detection zone the tracked object entered and which side of the detection zone the tracked object exited.
