The invention discloses an AR-HUD/LCD omnidirectional target detection and display method based on human eye attention, and belongs to the technical field of automatic driving, automobile environment perception, and intelligent cabins. The method comprises the following steps: acquiring a face image of a driver through a monocular camera; calibrating the monocular camera to obtain an internal reference matrix and a distortion parameter of the camera; carrying out distortion removal and graying on the image to obtain a self-quotient image; extracting a face area through a face detector, and then extracting coordinates of left and right pupils in an image plane of the monocular camera; according to the pupil image plane coordinates and pupil distance constraints, solving driver eye position space coordinates used for AR-HUD/LCD virtual image display. A neural network is used for detecting changes of a face angle of a driver, a driver attention vector is obtained, a target is detected in a vehicle-mounted panoramic image or an omnidirectional radar system according to the attention vector, and a detection object in an attention vector area is displayed through AR-HUD/LCD. According to the invention, system computing resources are saved, and the real-time performance of the detection system is improved.
