The invention discloses a high-speed rail box girder damage detection machine vehicle and a damage detection method. The machine vehicle comprises a bearing and walking module, a detection module, a control module and a data processing module. The bearing and walking module is provided with a bearing trolley; the detection module is arranged on the bearing trolley and is used for detecting and obtaining a panoramic image, ultrasonic information, a laser signal and pose information in the box girder; the control module is used for controlling the bearing trolley to realize self-walking and damage detection in the beam body according to the laser signal and the pose information; the data processing module is used for performing beam body internal surface crack image recognition based on a crack intelligent detection algorithm according to the box beam internal panoramic image to obtain crack information; according to the ultrasonic information, carrying out defect identification in the beam body based on an ultrasonic imaging technology to obtain defect information; and obtaining visual damage evaluation information according to the crack information and the defect information. Therefore, visual damage detection and evaluation of the high-speed rail box girder are realized.

    本发明公开了一种高铁箱梁损伤检测机器车及损伤检测方法,机器车包括:承载与走行模块、探测模块、控制模块和数据处理模块;承载与走行模块具有承载小车;探测模块设置在承载小车,用于探测获取箱梁内部全景图像、超声信息、激光信号及位姿信息;控制模块,用于根据激光信号及位姿信息,控制承载小车实现梁体内自行走及损伤探测;数据处理模块,用于根据箱梁内部全景图像,基于裂缝智能检测算法进行梁体内部表面裂缝图像识别,得到裂缝信息;根据超声信息,基于超声成像技术进行梁体内部缺陷识别,得到缺陷信息;根据裂缝信息及缺陷信息得到可视化损伤评估信息。从而实现高铁箱梁的可视化损伤检测及评估。
