Embodiment
[0057] The video sequence used in this embodiment is a scene sequence of police checkpoint monitoring.
[0058] The bus type identification method that the present embodiment relates to, comprises following specific steps:
[0059] Step 1: Carry out mixed Gaussian background modeling on the video sequence to obtain the foreground image of the vehicle to be processed.
[0060] Step 2: Under the world coordinate system, carry out preliminary recognition of the bus type on the obtained vehicles.
[0061] The specific steps are:
[0062] 1. Extract the contour of the vehicle foreground image to obtain N connected regions Ω k ,k=1,2,...,N, for each connected region Ω k , you can get a containing Ω k and the smallest rectangular region R k ,k=1,2,...,N.
[0063] 2. In the world coordinate system, by the rectangle R k bottom two dots p 1 ,p 2 Construct the judgment point p m ,specifically is:
[0064] p m ...
