Pedestrian relationship identification method, device and system and electronic device

[0032] Embodiment 1 of the present invention provides a pedestrian relationship identification method, see figure 1 The flow chart of the pedestrian relationship recognition method shown in the figure, the method includes the following steps:

[0033] Step S102, analyzing the orientation information of pedestrians within the target range in real time according to the group recognition algorithm to obtain the target group.

[0034] The group recognition algorithm can identify groups by tracking the changes in the degree of intimacy between pedestrians and groups, and judging the group belonging of pedestrians. Using the orientation information of each pedestrian, identify the group belonging of each pedestrian through a certain group identification algorithm. The target group can be any of a number of groups. The target range can be set according to the needs.

[0035] Step S104, extracting facial features of each group member in the target group.

[0061] Embodiment 2 of the present invention provides a pedestrian relationship recognition device, see Figure 6 The structural block diagram of the pedestrian relationship recognition device shown, the device includes:

[0062] The group determination module 61 is used to analyze the orientation information of pedestrians in the target range in real time according to the group recognition algorithm to obtain the target group; the feature extraction module 62 is used to extract the face features of each group member in the target group; the scoring module 63, It is used to perform two-by-two cross-validation on the group members according to the face features to obtain the kinship score between each two group members; the recognition module 64 is used to determine the target group member according to the kinship score and the preset threshold, and according to Target group members and kinship scores generate a kinship network; in the kinship network, target group members ar

[0066] Embodiment 3 of the present invention provides a pedestrian relationship recognition system, see Figure 5 The schematic block diagram of the structure of the pedestrian relationship recognition system shown, the system includes:

[0067] Family library, image acquisition module, group library, group identification module, face detection module and relative identification module; image acquisition module is used to collect pedestrian information and send pedestrian information to group library; group library is used to receive and store pedestrian information ; The group database is connected to the group recognition module by communication; the group recognition module is used to analyze the pedestrian information within the target range in real time according to the group recognition algorithm to obtain the target group; the face detection module is used to extract the faces of each group member in the target group features; the face detection module communicates wi
