The complexity of the steel plant environment leads to high requirements for real-time detection and identification of ladle license plate.An image segmentation method based on the HSV color space information is proposed for real-time detection and dynamic tracking.According to the HSV color space,regardless of the relation of brightness and color,the color image is converted from RGB space to HSV space.We can locate the position of the ladle license plate according to feature selection principles based on color and shape of the numeral cards,and the lean angle of image is found out according to the method of linear least squares fitting.Then the original oblique image can be adjusted by using the method of rotate transformation.Experiments show that the method can locate the Ladle license plate and correct tilt with high reliability and stability.

Key words: HSVcolor space;color image process;adjustment
