Abstract

This invention discloses a triggered optical countermeasure attack method, system, electronic device, and storage medium. The method includes optimizing an antagonistic patch based on a loss function and designing a trigger. Light beams are used to illuminate a designated area of ​​the antagonistic patch, activating the antagonistic patch's adversarial properties and implementing an attack against an autonomous driving target detection model. The loss function includes a first loss function for the antagonistic patch when the light beam is absent from the designated area and a second loss function for when the light beam is superimposed on the designated area. This function is used to control the antagonistic attack effectiveness of the antagonistic patch when the light beam is superimposed. This method can achieve an attack against an autonomous driving target detection model.
