Arch rib segment hoisting construction method based on binocular stereoscopic vision and electric hoist
The invention belongs to the technical field of intelligent construction of engineering structures, and discloses an arch rib segment hoisting construction method based on binocular stereoscopic vision and an electric hoist, which adopts binocular stereoscopic vision to position a target on an arch rib segment, reconstructs a three-dimensional coordinate of the target and calculates a deviation from a target position; and the electric hoist is controlled through a PID algorithm to realize automatic and accurate hoisting of the arch rib, so that the purpose of efficient construction is achieved. The method comprises the following steps: firstly, calibrating a binocular stereoscopic vision system to obtain internal and external parameters of cameras and a rotation matrix and a translation vector of a second camera relative to a first camera; automatically identifying and positioning the target on the arch rib section by adopting a calibrated binocular stereoscopic vision system, and calculating a three-dimensional coordinate of the target and a deviation value between the target and a target position; and a PID algorithm is applied to control the electric hoist to automatically hoist the arch rib section, and correction is performed according to a binocular stereoscopic vision measurement result, so that efficient construction in the arch rib section hoisting process is realized.
本发明属于工程结构智能建造技术领域，公开了一种基于双目立体视觉与电动葫芦的拱肋节段吊装施工方法，采用双目立体视觉对拱肋节段上的靶标进行定位，重构其三维坐标并计算与目标位置的偏差，通过PID算法控制电动葫芦来实现拱肋自动精准吊装，以达到高效施工的目的。该方法包括以下步骤：首先，对双目立体视觉系统进行标定，得到相机内外参数以及第二相机相对于第一相机的旋转矩阵和平移向量；采用已标定的双目立体视觉系统，对拱肋节段上的靶标进行自动识别与定位，计算靶标三维坐标及其与目标位置的偏差量；运用PID算法，控制电动葫芦进行拱肋节段自动吊装，同时根据双目立体视觉测量结果进行修正，从而实现拱肋节段吊装过程高效施工。
