The invention discloses a projection vehicle lamp illumination method and device based on image semantic segmentation target recognition. The method comprises the steps of 1, obtaining calibration parameters of a camera and a projection vehicle lamp on each side; step 2, obtaining structured data of the current image frame through a semantic segmentation model, obtaining related information of each target instance, and filling the related information of the target instance into the structured data of each corresponding target instance; 3, calculating the illuminance of each target instance; and step 4, converting the contours of the target instances from the image coordinate system of the current image frame to a projection vehicle lamp coordinate system, performing pixel-level brightness filling on a closed area formed by the contours of the target instances on the basis of the structured data of the target instances according to corresponding illuminance, generating a projection bitmap, and displaying the projection bitmap. The bitmap is used as a projection lighting scheme of a projection vehicle lamp array. According to the invention, the vehicle lighting system can be improved to realize the blind compensation and anti-dazzling effects.
