| 摘 要： | 列车通常利用里程计实现连续定位,但其累积误差必须加以修正.由于轨检车无法利用传统方法校正里程计累积误差,本文提出一种利用地面标志图像进行轨检车位置定点校正方法.它利用安装在轨检车顶部的相机获取相机前方的图像,通过地面标志在图像中的像素坐标计算它到相机的距离,然后由该距离和事先存储的地面标志实际位置计算轨检车位置.本文首...

| Abstract: | The odometer is usually used to accomplish consecutive train positioning,however,the accumulative error of the the odometer must be corrected.Since the accumulative error of the track inspection car can not be corrected with the traditional method,the novel track inspection car position correction method by use of the single landmark image is proposed.The actual distance between the landmark and the camera optical center is calculated with the image acquired by a camera fixed on the top of the track inspect... |
