Real-time monitoring method for hoisting of steel truss girder
The invention relates to a real-time monitoring method for hoisting of a steel truss girder, and belongs to the field of bridge engineering construction. The real-time monitoring method comprises the steps that a binocular recognition camera is installed at the splicing end of an upper chord of a to-be-erected steel truss girder, and two GNSS receivers are installed at the splicing end of the to-be-erected steel truss girder and the splicing end of an erected steel truss girder respectively; the steel truss girder to be erected is lifted, and the binocular vision camera is used for measuring the real-time distance L1 between the splicing end of the steel truss girder to be erected and the splicing end of the erected steel truss girder; measuring a three-dimensional coordinate O1 of the spliced end of the erected steel truss girder and a three-dimensional coordinate O2 of the spliced end of the to-be-erected steel truss girder by using the two GNSS receivers, and calculating a real-time distance L2 between the erected steel truss girder and the spliced end of the to-be-erected steel truss girder by using the O1 and the O2; and calculating an accurate distance value L between the splicing end of the steel truss girder to be erected and the splicing end of the erected steel truss girder by utilizing the weight coefficient.
本申请涉及一种钢桁梁吊装的实时监控方法，属于桥梁工程施工领域。该实时监控方法包括将双目识别相机安装于待架设钢桁梁上弦杆拼接端头，将两台GNSS接收机分别安装于所述待架设钢桁梁拼接端头和已架设钢桁梁拼接端头上；起吊所述待架设钢桁梁，利用所述双目视觉相机测量出所述待架设钢桁梁拼接端头与所述已架设钢桁梁拼接端头之间的实时距离L1；利用两台所述GNSS接收机测得所述已架设钢桁梁拼接端头三维坐标O1与所述待架设钢桁梁拼接端头的三维坐标O2，利用O1与O2计算出所述已架设钢桁梁与所述待架设钢桁梁拼接端头之间的实时距离L2；利用权重系数，计算出所述待架设钢桁梁拼接端头与所述已架设钢桁梁拼接端头之间的精确距离值L。
