DEVICE FOR DETECTING SIGNS OF ANTISOCIAL BEHAVIOUR Russian patent published in 2023 - IPC G08B23/00 G06F18/21 

FIELD: devices for monitoring crowded places.

SUBSTANCE: device for detecting signs of antisocial behaviour comprises a series-connected video information recording unit, an object detection unit and a unit for determining the spatial coordinates of an object, the output is connected to the first input of the complex analysis unit, the subject detection unit, the input of which is connected to the second output of the video information recording unit, one of the outputs is connected to the second input of the complex analysis block through the unit for determining the spatial coordinates of the subject and the unit for constructing the frame of the subject connected in series, and the other outputs of the subject detection unit are connected respectively to the inputs of the units for registering the direction of the subject’s gaze, calculating the pupil/iris ratio and analysing facial expressions, outputs connected respectively to the third, fourth and fifth inputs of the complex analysis unit, a fire and smoke detection unit connected between the third output of the video information unit and the sixth input of the complex analysis unit, a unit for analysing the subject's movement trajectory, the input of which is connected to another input of the unit for determining the spatial coordinates of the subject, and the output to the seventh input of the complex analysis unit, the audio information recording unit, the noise detection unit and the speech recognition unit connected in series, connected by the output to the eighth input of the complex analysis block, the unit for generating the device operation log, the input of which is connected to the output of the complex analysis block, and inputs/outputs to the outputs/inputs of the memory unit and interfaces for interfacing, respectively, with wireless and wired data transmission systems for interaction with external services.

EFFECT: increasing the reliability of detecting signs of antisocial behaviour in crowded places.
