Zusammenfassung:	Disclosed are a drill hole information acquisition method and device based on DIC technology, relating to the technical field of mining. According to the method, panoramic image capturing is performed on a sampling hole in a roadway surrounding rock according to a certain time period, and sampling hole images at different times are compared and analyzed and calculated to obtain drill hole information free from the influence of initial fissures. The device comprises a measuring bar (1), a cable (6), a winch (7), a pulse generator (8), a host (9) and a panoramic camera (10), wherein the panoramic camera (10) is fixedly arranged at an end of the measuring bar (1), the panoramic camera (10) is connected to the host (9) by means of the cable (6), the cable (6) is wound around a roller of the winch (7), the winch (7) can be used for triggering the pulse generator (8), and the pulse generator (8) is electrically connected to the host (9). By means of the method and device, due to being free from the influence of ini
