The invention relates to a train approaching early warning method. The method comprises the following steps that a circular signboard image is collected and preprocessed; performing unique setting circle Hough transform to obtain the circle center and the radius of the circular region of the signboard, and calibrating the color gamut of the circular region; calculating the real color gamut of the circular area of the signboard, and judging the approaching direction of the train.
本发明涉及一种列车接近预警方法,包括以下步骤:采集圆形标识牌图像并预处理;进行唯一整定圆霍夫变换,获取标识牌圆形区域的圆心和半径,标定圆形区域的色域;计算标识牌圆形区域的现实色域,判定列车接近的方向。
