摘要
为提高矿井机车定位系统的稳定性,提出利用双目视觉技术实现机车定位的方法。由巷道顶部设置的标志牌外层红色特征确定2幅图像的感兴趣区域,提取该区域内各层正方形边界的拐角获得特征点,通过相应计算实现机车的定位。实验结果表明,该方法距离测量误差小,是一种有效的定位方法。
To improve the stability of mine locomotive posmonlng system, the positioning mine locomotive based on binocular vision is presented. The rectangular reflecting plates are placed on top of roadway. The region of interest is achieved by outer red features. All points of the rectangular region are extracted. And then, the positioning results are improved by corresponding calculations. The experimental results show that the method distance measurement error is smaller, which is an effective way for mine locomotive positioning.
