The invention discloses a method and a system for monitoring a wound state. According to the method, related physiological data of a wound surrounding area and a reference area are extracted from image data, further processed and then input into a wound state classification prediction model for wound state judgment, and wound state monitoring is achieved. The system comprises a wound monitoring device and a wound state detection server, the wound monitoring device comprises a double-camera video image acquisition unit, a temperature measurement and calculation unit, a physiological data extraction unit, a first communication unit and a display unit; the wound state detection server comprises a second communication unit, a wound state classification prediction model construction unit, a wound state evaluation unit and a storage unit. The physiological data of the skin around the wound are monitored through a non-contact method to judge the wound state, on the premise that wound exposure is reduced, abnormal wounds can be found as soon as possible, especially the problems of early infection of the wounds, poor blood circulation of the wounds and the like, and medical staff can conveniently adjust a treatment scheme in time.
