提出一种基于改进Hough变换的调车信号灯识别算法。算法利用信号灯图案的几何性质简化了计算,可以应用快速变化的实时图像序列。对现场获取的图像序列的处理验证了本算法的有效性。
A shunting signal recognition algorithm based on improved Hough transform is proposed. The algorithm makes use of the geometric properties of the traffic light pattern to simplify the calculation and allows the use of rapidly changing real-time image sequences. The processing of the image sequences acquired at the field verifies the effectiveness of the proposed algorithm.
