The invention relates to a method for achieving docking distance measurement of a parking apron gallery bridge based on machine vision, and the method comprises the steps: (1) collecting the real-time image information of an airplane and the gallery bridge through a camera disposed on the gallery bridge, and converting the real-time image information from an RGB space image to an HSV space image; (2) selecting an ROI region according to the set threshold value of the HSV space image to determine the region where the airplane and the gallery bridge platform are located, and converting the HSV space image into a grey-scale map; (3) carrying out edge detection on an ROI (Region of Interest) in the grey-scale map; (4) performing straight line detection on the image obtained after edge detection, and performing screening and edge optimization on the detected straight lines; (5) calculating the pixel distance from the gallery bridge platform to the edge of the aircraft; (6) calculating an included angle between the gallery bridge platform and the edge of the aircraft, and removing abnormal data in the included angle; and (7) drawing the detected straight line at a corresponding position of the image, and carrying out corresponding alarm reminding according to the detected distance and angle.
本发明涉及一种基于机器视觉实现停机坪廊桥对接测距的方法,其中,该方法包括:(1)使用安装在廊桥上的相机采集飞机和廊桥的实时图像信息,并将该实时图像信息从RGB空间图像转换成HSV空间图像;(2)根据设置的HSV空间图像的阈值选取ROI区域确定飞机和廊桥平台所在的区域,并将HSV空间图像转换为灰度图;(3)对所述的灰度图中的ROI区域进行边缘检测;(4)对经过边缘检测后得到的图像进行直线检测,并对检测到的直线进行筛选和优化缘;(5)计算廊桥平台到飞机边缘的像素距离;(6)计算廊桥平台到飞机边缘的夹角,并剔除其中存在的异常数据;(7)将检测到的直线绘制在图像的对应位置上,并根据检测到的距离和角度进行相应的警报提醒。
