COUNTING APPARATUS AND METHOD FOR MOVING OBJECTS

摘要

A counting apparatus and method for counting moving objects by calculating the number of moving objects in each region based on linear regression, calculating the number of increased moving objects in each region according to the undirected graphs built based on optical flows, and counting according to the number of the moving objects and the number of the increased moving objects in each region, repeated counting may be avoided, and fast and accurate real-time counting may be achieved.

1. A counting apparatus for moving objects, comprising:
a first extracting unit configured to extract images having the moving objects to obtain extracted images; a first modeling unit configured to perform background modeling on the extracted images, to obtain binarized images; a first segmenting unit configured to perform group segmentation on the binarized images to produce regions; a first calculating unit configured to calculate features of each region after the group segmentation according to preobtained scaling parameters; a second calculating unit configured to calculate a first number of moving objects in each region according to the features of each region and preobtained linear regression coefficients; a third calculating unit configured to calculate a second number of increased moving objects in each region according to undirected graphs built based on optical flows; and a first determining unit configured to determine a third number of moving objects in the images according to the first number of moving objects and the second number of increased moving objects in each region.
