The invention belongs to the technical field of engineering machinery, and particularly relates to a telescopic screed control method and system and a paver. The telescopic screed control method comprises the following steps: acquiring image information of a road edge in the operation process of the paver; performing identification and correction processing on the image information of the road edge, and outputting pixel coordinates of the road edge; and controlling a telescopic screed of the paver to perform corresponding telescopic motion according to the pixel coordinates of the road edge. According to the method, the real-time following of the road edge position and the self-adaptive adjustment control of the telescopic screed plate are realized in a visual image acquisition mode, the method is not easily interfered by a field environment, complicated calibration operation is not needed, and related acquisition equipment is simple in structure, high in reliability, wide in road edge type identification range and higher in universality; and meanwhile, the response speed and the accuracy of adjustment operation can be effectively improved, the defects of paving operation edge gaps and the like caused by irregular operation areas or deviation of the running path of the paver are overcome, and the construction efficiency and the construction quality can be improved.
本发明属于工程机械技术领域，具体涉及伸缩熨平板控制方法、控制系统和摊铺机。伸缩熨平板控制方法包括：在摊铺机作业过程中获取路沿的图像信息；对路沿的图像信息进行识别和校正处理，输出路沿的像素坐标；根据路沿的像素坐标控制摊铺机的伸缩熨平板进行相应的伸缩运动。本发明通过采集视觉图像的方式，实现路沿位置实时跟随和伸缩熨平板的自适应调整控制，不易受到现场环境的干扰，无需复杂的标定操作，相关采集设备结构简单，可靠性高，对路沿类型的识别范围广，通用性更强，同时能够有效提高调整操作的响应速度和准确性，防止因作业区域不规则或摊铺机行驶路径偏差而导致的摊铺作业边缘缺口等缺陷，有利于提高施工效率和施工质量。
