Vehicle-mounted HUD calibration system and method

Abstract

The invention relates to the field of HUDs, and discloses a calibration system and method of a vehicle-mounted HUD.The system comprises a calibration data acquisition module, a data preprocessing module, a calibration analysis module, a calibration effect evaluation module, a calibration correction module and a dynamic adjustment module; the method comprises the steps of preprocessing calibration data, extracting calibration characteristic parameters influencing calibration from the preprocessed calibration data, analyzing whether the calibration characteristic parameters have calibration errors or not, and comprehensively analyzing the calibration effect to evaluate whether the calibration effect of the HUD is within a reasonable range or not in real time. By comparing the calibration effect evaluation coefficient with the calibration effect threshold value, the calibration of the HUD is dynamically adjusted in real time, the calibration error can be detected more accurately, the accuracy and reliability of the calibration result can be improved, the calibration state of the HUD can be known in real time, feedback adjustment can be made in time, and the user experience is further improved.
