| Summary: | In view of problem of single detection method and low accuracy for behaviors of no card, multi-card and substitute card of out-in personnel in mine personnel location system, a marking card uniqueness detection device based on face recognition technology was designed. When the personnel pass by the device, security inspection door scans face feature information of personnel automatically and sends the information to detection host. If finding the person carries multi-card, the detection host immediately downloads command to make sound and light alarm, otherwise the detection host makes quick face recognition comparison. The actual application showed that the device can quickly judge behaviors of no card, multi-card and substitute card of out-in personnel and has higher stability and recognition rate.
