Abstract:
A body fall smart control system includes at least one image capturing module used for capturing a video image and an image processing module connected to the image capturing module. The image processing module is used for performing body pattern identification on the captured video image, establishing a 2D or 3D model of the identified body pattern, tracking whether a signal change speed and/or angle of the modeled body pattern reaches a set threshold value to determine whether a fall has occurred, and controlling an alarm module to sound an alarm if a fall has occurred. A 2D or 3D model compares and analyzes the speed, angle, associated help voice, etc. of a falling body to determine whether a fall has occurred, and sounding an alarm and sending a signal for manual braking or automatic braking etc. and controlling an action of a related device if the comparison is successful.

Claim (Index 2):
The body fall smart control system according to  claim 1 , wherein the image processing module comprises the following steps for video image processing:\n (1) detection of moving target: the video image is processed into an image sequence, and it is determined whether a moving target appears in each frame of the image sequence, if so, the moving target is positioned; (2) tracking of moving target: a correspondence relationship is established between body areas in consecutive frames; (3) feature extraction method: a contour feature point of the body is extracted to form a contour state of a certain regular shape; and (4) behavior identification: the contour state obtained in the step (3) is subjected to body pattern identification and modeling in a space-time zone, and a signal change speed of the modeled body pattern is tracked to determine whether the body is in a normal state or an abnormal state; if the body is in an abnormal state, the change speed and/or angle of the contour state in the consecutive frames is analyzed, and it is determined whether the change speed and/or angle reaches the set threshold, if so, a fall is determined to have occurred.
