METHOD AND SYSTEM FOR CALCULATING PASSENGER CROWDEDNESS DEGREE
First Claim
1. A method for calculating a passenger crowdedness degree, characterized in that the method comprises:
- establishing a video data collection environment and starting collecting video data of passengers getting on and off;
reading the collected video data of passengers getting on and off and pre-processing a plurality of successive image frames of the video data;
identifying a human head according to the pre-processing result and taking the detected human head as a target object to be tracked by mean-shift; and
judging the behaviours of getting on and off of a passenger in the area where the target object is positioned and determining the crowdedness degree of passengers inside a vehicle according to the numbers of passengers getting on and off.

Abstract
The disclosure provides a method for calculating a passenger crowdedness degree, comprising: establishing a video data collection environment and starting collecting video data of passengers getting on and off; reading the collected video data of passengers getting on and off and pre-processing a plurality of successive image frames of the video data; identifying a human head according to the pre-processing result and taking the detected human head as a target object to be tracked by mean-shift; and judging the behaviours of getting on and off of a passenger in the area where the target object is positioned and determining the crowdedness degree of passengers inside a vehicle according to the numbers of the passengers getting on and off. The disclosure also provides a system for calculating a passenger crowdedness degree. The disclosure can effectively reduce the false detection, leak detection and error detection of the head top.

5. A system for calculating a passenger crowdedness degree, characterized in that the system comprises:
-
a data collection module, which is configured to establish a video data collection environment and start collecting video data of passengers getting on and off; a pre-processing module, which is configured to read the collected video data of passengers getting on and off and pre-process a plurality of successive image frames of the video data; an object determination module, which is configured to identify a human head according to the pre-processing result and take the detected human head as a target object to be tracked by mean-shift; and a crowdedness judgment module, which is configured to judge the behaviours of getting on and off of a passenger in the area where the target object is positioned and determine the crowdedness degree of passengers inside a vehicle according to the numbers of passengers getting on and off. - View Dependent Claims (6, 7, 8)
