Pavement crack chromatic aberration-free intelligent repairing system and method based on image recognition
The invention discloses a pavement crack chromatic aberration-free intelligent repairing system and method based on image recognition. The pavement crack chromatic aberration-free intelligent repairing system comprises an underframe unit, an asphalt pavement grooving unit, an asphalt pavement repairing material mixing unit and a control unit, the asphalt pavement grooving unit and the asphalt pavement patching material mixing unit are respectively fixed on the underframe unit, and the control unit is respectively connected with the asphalt pavement grooving unit and the asphalt pavement patching material mixing unit. The control unit identifies a crack based on the asphalt pavement surface image information, and fits a crack function curve according to the distribution condition of crack pixel point pairs; and according to the curvature of the fitted curve, planning the slotting track and the slotting depth of the crack groove in a segmented manner. According to the invention, the functions of crack identification, grooving track determination, use amount calculation of repairing materials and the like are integrated, the cutting knife can be automatically controlled to carry out grooving cutting according to the determined grooving track and depth, and intelligent identification and repairing of asphalt pavement cracks are realized.
本发明公开了一种基于图像识别的路面裂缝无色差智能修补系统及方法，包括：底架单元、沥青路面开槽单元、沥青路面修补料拌合单元和控制单元；沥青路面开槽单元和沥青路面修补料拌合单元分别固定在底架单元上，控制单元与沥青路面开槽单元和沥青路面修补料拌合单元分别连接。控制单元基于沥青路面表面图像信息识别出裂缝，根据裂缝像素点对的分布情况，拟合裂缝函数曲线；根据拟合曲线曲率分段规划裂缝槽的开槽轨迹和开槽深度。本发明集裂缝识别、开槽轨迹确定以及修补材料的用量计算等功能为一体，能够自动控制切割刀按照确定的开槽轨迹和深度进行开槽切割，实现沥青路面裂缝的智能识别和修补。
