The invention discloses an AR-HUD image calibration adjustment system and method based on a high-precision map system. It includes the ADAS system, which is used to output the first coordinate information of the vehicle relative to the P point to the high-precision map marking device, and the P point is any point on the calibrated road surface element; the high-precision map marking device is used to obtain the vehicle relative to Based on the second coordinate information of point P, calculate the error of the ADAS system according to the first coordinate information and the second coordinate information, and send the calculated error to the augmented reality head-up display; Pavement elements are compensated and an image of the compensated pavement elements is displayed. The invention uses a portable high-precision map calibration system to calibrate ADAS of different models, thereby improving the final imaging accuracy of AR-HUD, ensuring that AR-HUD imaging can be well matched with road surface elements, and improving customer experience.
Description
technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to an AR-HUD image calibration adjustment system and method based on a high-precision map system. Background technique [0002] The AR-HUD system mainly includes the AR-HUD body / ADAS system, and the road signal provided by the ADAS system is used as the input of the AR-HUD display. During real vehicle debugging, the AR-HUD is mainly used to match the ADAS signal, so that the AR-HUD imaging and the actual elements of the road surface can be well overlapped to ensure the actual experience of the system. However, the ADAS system itself has the problems of low precision and great influence by the use environment. Due to these fluctuations, it is difficult for AR-HUD to find a suitable imaging adjustment median value during real vehicle debugging, resulting in mismatch between AR-HUD imaging and road surface elements. Good question, reduce customer experience feeling. ...
