Problems solved by technology

However, the camera often has monitoring blind spots, and it is difficult to cover the entire area. If unrelated personnel invade the area from the monitoring blind spot, the camera cannot detect the occurrence of area intrusion in time.

Abstract

The embodiment of the invention provides a region intrusion detection method and device. The method comprises the following steps: acquiring footstep voice in a to-be-detected area to obtain footstepvoice signals; extracting voiceprint features of the footstep voice signals as voiceprint features to be verified; based on the similarity between the voiceprint feature to be verified and an authenticated voiceprint feature, whether the footstep voice is the footstep voice of an authorized person is determined, and the authenticated voiceprint feature is the voiceprint feature extracted from a footstep voice signal of the authenticated person; if the footstep voice is not the footstep voice of the authorized person, determining that region invasion occurs in the to-be-detected region. Due tothe fact that intruders are difficult to avoid making footsteps in the moving process of the to-be-detected area, and the footsteps are not prone to being blocked by obstacles, the blind area of areaintrusion detection is small.

Description

Technical field [0001] This application relates to the technical field of voiceprint recognition, in particular to a method and device for regional intrusion detection. Background technique [0002] For some areas, users may not want irrelevant persons to enter these areas within a specific time period. For example, for property safety considerations, users do not want non-family members to enter their homes during their working hours. In order to determine whether there are unrelated persons invading these areas, regional intrusion detection can be performed on these areas. [0003] Suppose that cameras are deployed in these areas to collect surveillance images of these areas and identify people on the surveillance images to determine whether there are unrelated persons invading these areas. However, cameras often have blind spots for monitoring, and it is difficult to cover the entire area. If unrelated persons invade the area from the blind spots, the camera cannot detect the i...
