摘　　要：利用基于激光扫描测距与视频图像处理相结合的方法检测港口集装箱卡车位置,排除了环境变化的干扰,提高了定位精度,并且通过图形处理计算集装箱体之间的距离和夹角,准确的指导集装箱卡车停车以及预调双吊具的状态,从而加快装卸速度,提高了运行效率。Using an approach based on combination of laser scanning and video image process, the container＇s location was calculated, excluding the interference of environmental change. Through graphic processing, the container＇s offset angle was calculated and the container＇s physical location coordinates was received. This method can speed up container handling and improve port operation efficiency through accurately guiding container trucks parking and adjusting the status of dual-tackle.
