Beschreibung
Zusammenfassung:	A hole site information detection method, comprising: acquiring first scanning data and second scanning data of a detected structure during the process of scanning the detected structure by using a three-dimensional scanner, wherein the first scanning data is photometric-stereo scanning data of a positioning hole in the detected structure, and the second scanning data comprises non-photometric-stereo scanning data of the positioning hole, or, the second scanning data is non-photometric-stereo scanning data of other feature points except the positioning hole (S110); and determining hole site information of the positioning hole on the basis of the first scanning data and the second scanning data (S120). The photometric-stereo scanning data is detected in a photometric-stereo scanning mode, can comprise tiny changes in the surface of an object, and has the effects of enhancing the contrast between different feature points and reducing noise, such that hole site information with higher precision can be determined
