%X In the virtual advertisement system,we use several simple and effective algorithm to solve the field detection problem in the sport video.Firstly,through a method based on color space histogram,we automatically detect the main area venues.Secondly,through Top-hat transform and the improved otsu algorithm to detect area edge.Finally,the Hough line detection and the least squares fitting method of combining accurate detection of all lines.Through A large number of experiments show that this method has a good effect on badminton field,tennis field and table tennis field.The results can be used for camera calibration and venues reconstruction.
