The invention relates to the technical field of image data processing, and discloses a complex three-dimensional model directional confrontation attack texture generation method, which comprises the following steps: S1, specifying the weight of a target detection model; s2, changing an original index value of the target object into an index value of a to-be-classified category; s3, covering the three-dimensional model of the target object with the to-be-optimized adversarial attack texture, rendering a two-dimensional image of the three-dimensional target model of the target object according to the target object in the data set and the azimuth and attitude information of the camera, and synthesizing the two-dimensional image with a scene in the data set by using a physical transformation function to form an adversarial sample; s4, inputting the adversarial sample into the target detection model, calculating classification loss, bounding box loss and confidence coefficient loss according to the original defini
