Abstract
本发明公开了一种基于自适应变焦的桥梁动态巡检视觉感知系统及方法，系统包括感知模块、变焦对焦控制模块、标定模块、图像质量评价模块和病害识别定位模块；变焦对焦控制模块用于根据感知模块获取的运动参数、距离信息构建自适应变焦策略，并采用变焦‑对焦并行协同控制方式实现快速精准对焦；标定模块用于实现变焦相机的内参智能标定及IMU、激光测距仪、变焦相机的多传感器联合标定；图像质量评价模块用于对变焦相机采集的图像进行清晰度评价，并根据评价结果触发焦距二次微调；病害识别定位模块用于对清晰图像进行桥梁表观病害识别分割，并结合标定参数实现病害的三维空间定位，能够适配桥梁动态巡检的复杂工况，大幅提升巡检的效率与精度。
