Abstract
本发明涉及桥梁无损检测技术领域，公开了一种面向缆索承重桥拉 / 吊索内力测试的无人机自主巡检方法及系统，该方法包括引导无人机飞行至目标停靠平台所在的空间区域，完成无人机的自主停靠；获取不同扫描角度下的距离谱数据构建角度‑距离矩阵；进行校准扫描确定最优观测角度；对目标斜拉 / 吊索进行静态观测获取振动响应信号；提取目标斜拉 / 吊索的振动频率特征；计算目标斜拉 / 吊索的索力并输出索力比，完成单个观测点位的检测任务；根据巡检路径飞行至下一个停靠平台，重复执行巡检步骤直至完成全部预设观测点位的检测任务。本发明可有效克服风力扰动、无人机自身振动、续航不足及定位不准等问题，大幅提升拉吊索结构的检测精度和巡检效率。
