The invention provides an accurate eye-positioning method. The method includes the steps of controlling a drive motor in a window top trim to rotate through a single-chip microcomputer, connecting the output end of the drive motor to an infrared camera through a 360-degree coupler, allowing the single-chip microcomputer to output a scan control program, controlling the drive motor to drive the infrared camera to scan the face of a person on a driver's seat, recording rotational angle of the drive motor through single-chip microcomputer software, and outputting data of rough positions of eyes; allowing the infrared camera to capture infrared spectrum of the face, and outputting an infrared spectrum signal to an image recognition module; allowing the image recognition module to recognize an infrared image taken by the infrared camera, selecting eye positions according to infrared features of the eyes and outputting data of accurate positions of the eyes; allowing a controller to receive the data of rough positions from the single-chip microcomputer and the data of accurate positions output by the image recognition module, and calculating the accurate positions of the eyes of a driver.
