SYSTEM AND METHOD FOR MONITORING MOTION OBJECT
First Claim
1. A motion object monitoring system comprising:
- a time-of-flight (TOF) camera to capture a scene to obtain an image of the scene and distance data between a plurality of points in the scene and the TOF camera;
a processor; and
a storage device connected to the processor and storing one or more computerized instructions to be executed by the processor, wherein the storage device comprises;
a three-dimensional (3D) model module to build a 3D model of the scene according to the image of the scene and the distance data between the plurality of points in the scene and the TOF camera;
an information gathering module obtaining specific features of the monitored objects by detecting the built 3D model of the scene, and giving numbers to each of the monitored objects according to the specific features;
a storing and comparing module storing one of the given numbers of each of the monitored objects; and
a processing module analyzing the given numbers stored in the storing and comparing module.

Abstract
A motion object monitoring system captures an image of a scene and distance data between points in the scene and a time-of-flight (TOF) camera by the TOF camera. A 3D model of the scene is built according to the image of the scene and the distance data. The motion object monitoring system gives numbers to the monitored objects according to specific features of the monitored objects. The specific features of the monitored objects are obtained by detecting the built 3D model of the scene. Only one of the numbers of each of the monitored objects is stored, instead of repeatedly storing the numbers of same motion objects. The motion object monitoring system analyzes the stored numbers, and displays an analysis result. The motion object monitoring system also determines a movement of each of the motion objects according to corresponding numbers of the motion objects.

17. A motion object monitoring method comprising:
-
capturing a scene by a time-of-flight (TOF) camera to obtain an image of the scene and distance data between a plurality of points in the scene and the TOF camera; building a three-dimensional (3D) model of the scene according to the image and the distance data; obtaining specific features of each of the motion objects by detecting the built 3D model of the scene by an information gathering module; giving numbers to the motion objects by an information gathering module, wherein each of the numbers of each of the motion objects comprises a feature portion representing specific features of the motion object, a position portion representing a coordinate position of the motion object in the monitored area, and a time portion representing a time when the motion object appears at the coordinate position; storing the given numbers in a data storing unit; reading the position portions and the time portions of the given numbers with same feature portions from the data storing unit, and determining a movement of each of the motion objects by sequencing the position portions according to corresponding time portions by an object tracking unit; and displaying the movement of each of the motion objects by a displaying unit.
