Problems solved by technology
[0005] The present invention introduces the idea of spatio-temporal behavior correlation, and provides a spatio-temporal relationship matching and correlative identification method for masks and disguised identities. Through matching and analysis of spatio-temporal motion data, the unreasonable spatio-temporal behavior of the target can be found, and the problem can be solved by relying solely on visual attributes. Unable to correlate the problem of disguising pedestrians

Embodiment Construction
[0015] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit this invention.
[0016] The invention finds that the trajectory of a pedestrian near the incident point suddenly disappears through pedestrian re-identification and tracking, and judges whether the disappearance trajectory is caused by the perpetrator's disguising by matching the time-space relationship between the disappearance trajectory and the crime location and crime time. track segment. Such as figure 1 The technical principle shown is that the spatio-temporal relationship matching is divided into the matching probability of the spatio-temporal relationship between the...

The invention discloses a space-time relationship matching association identification method for masked and reloading camouflage identities, and the method comprises the steps: firstly calculating apre-case space-time relationship matching probability through employing case occurrence time, target disappearance time and the passing duration of a target from a disappearance position to a case occurrence point, and measuring the space-time relationship matching degree of the target disappearance time and case occurrence time; calculating a post-case space-time relationship matching probabilityby utilizing the target reproduction time, the case termination time and the passing duration of the target from the case occurrence point to the reproduction position, and measuring the space-time relationship matching degree of the target reproduction time and the case termination time; calculating a joint matching probability according to the two spatial-temporal relationship matching probabilities, and measuring the spatial-temporal relationship matching degree of the pedestrian disappearing track and the case; and finally discovering a camouflage target and identifying the identity basedon the joint matching probability. According to the method, the thought of spatial-temporal behavior association is introduced, and the problem that morphology camouflage pedestrians cannot be associated by independently depending on visual attributes is solved.
Description
technical field [0001] The invention belongs to the technical field of identity identification, and relates to a disguised identity association identification method, in particular to a spatio-temporal relationship matching association identification method of masking and disguised identity. [0002] technical background [0003] When criminals carry out serious criminal activities such as bank robbery, in order to avoid the identification of surveillance cameras, they often wear masks and camouflage, which makes the suspect identification technology based on face recognition invalid, but criminal investigators can still rely on face recognition. Facial recognition technology tracks criminals. Face recognition is based on cross-camera pedestrian re-identification technology, which comprehensively uses the characteristics of human body appearance, upper and lower body clothing, clothing, wearables, hairstyle, body shape, height, gender, age, walking posture, face and other cha...
