In the research on concrete with defects, most scholars have detected the defects of concrete.
Zhao Chuanping et al.
used indoor testing methods to study the intelligent detection of internal defects in concrete based on ultrasonic method; Zhu Hongwu used phased array ultrasonic imaging method to detect internal defects in concrete; Yu Xiaofei et al.
studied the detection of defects in basement floor concrete using phased array ultrasonic imaging method; Jiang Wenhao and others used unmanned ships equipped with side scan sonar to explore and quantify defects in underwater concrete structures; Cao Guojin et al.
used deep learning computer vision methods to study the detection of surface defects in hydraulic concrete structures.
