摘要: 分析了架桥施工中运梁车工作的特点,针对其在车辆导向方面所存在的主要问题,并结合现场需求,设计了一种基于单片机实现的嵌入式图像处理的新型车辆辅助导向装置,完成了相关硬件平台的设计,给出了在单片机系统中实现视频采集、图像处理、车辆跑偏判断和报警输出等关键技术细节的具体方法.实验结果表明,该辅助导向装置满足了运梁车在轨道梁上的行驶要求.该装置已应用于现场实际,其设计和实现方法对于其他大型工程车辆导向装置的研发具有较高的参考价值.Abstract: The feature of elevating transporter in bridging construction was analyzed. Aimed at the primary problem of vehicle′s guidance and on-site′s practical requirement, a new kind of auxiliary device for vehicle′s guidance based on embedded image processing using single chip microcomputer was developed. The relevant hardware platform was designed, and such key technologies in single chip microcomputer system as video acquisition, image processing, judgment of vehicle′s off tracking and output of alarm were introduced in detail. The results of experiments revealed that this device meeted the traveling requirement of the elevating transporter on the track-beam. The device was applied in field construction, and the method of design and implementation is well worthy for other large-scale field vehicle′s guidance.
