A head-up displaying system, comprising a projector for a head-up displaying system, comprising:

• a displaying component configured to project an image, and
• a three-mirror optical device positioned in an optical path of an emergent light of the displaying component, configured to reflect the image projected by the displaying component onto a front windshield such that the front windshield reflects the image to eyes of a driver, and comprising:
• a zoom lens assembly, comprising a zoom lens for zooming in/out the image projected by the displaying component, and a first curvature adjusting component configured to adjust a curvature of the zoom lens;
• an image quality compensation lens assembly, comprising an image quality compensation lens configured to compensate for an image quality distortion caused during a change of the curvature of the zoom lens, and a second curvature adjusting component configured to adjust a curvature of the image quality compensation lens;
• and
• a front windshield compensation lens assembly, configured to compensate for an image distortion caused by the front windshield.
