Abstract :
This paper proposes a method of automatic people counting used in air-conditioning energy-saving. The method has counted the number of people in the indoor environments through three modules: image pre-processing module, image marking module and people counting module, in order to control air-conditioning controller to achieve the purpose of saving energy. Through experiment comparing, image pre-processing module chooses image graying, Gaussian average filter, binarization and opening operation to optimize images. The following image marking module uses connected component detection algorithm, removing false contouring based on head shape properties and region marking. Finally, people counting module is used to count the number of people. The experimental results show that the method of automatic people counting about a large number of indoor images is effective and can maintain high statistics accuracy to those images which have little background noise. The method is very suitable for small cost of air-conditioning system to realize air-conditioning energy-saving and achieve the goal of energy saving.
