The invention relates to an HUD display control method based on augmented reality, and the method comprises the steps: receiving a corresponding display instruction, and obtaining the driving condition of a vehicle through a vehicle-mounted sensor based on the display instruction; determining at least one piece of driving assistance information associated with an assisted driving function based on the driving condition of the vehicle, and calling a 3D model of the at least one piece of driving assistance information from a driving assistance system; determining a coordinate position, a deflection angle and a to-be-displayed size of the 3D model relative to the vehicle, and respectively generating a corresponding transfer matrix M1, a scaling matrix M2 and a rotation matrix M3; combining the matrixes into a model matrix M0, and fusing the 3D model of the driving assistance information into a real driving scene of the vehicle based on the matrix M0; and projecting the fused driving scene to a virtual canvas in a front windshield of the vehicle. The invention further relates to a vehicle-mounted display device and a driving assistance system comprising the vehicle-mounted display device.
本发明涉及一种基于增强现实的HUD显示控制方法,包括:接收相应的显示指令,并基于该显示指令借助车载传感器获取车辆的行驶工况;基于车辆的行驶工况确定与辅助驾驶功能相关联的至少一个驾驶辅助信息,并从驾驶辅助系统中调取所述至少一个驾驶辅助信息的3D模型;确定所述3D模型相对于车辆的坐标位置、偏转角度以及待显示尺寸,并分别生成相应的转移矩阵M1、缩放矩阵M2和旋转矩阵M3;将这些矩阵组合成一个模型矩阵M0,并基于该矩阵M0将所述驾驶辅助信息的3D模型融合到车辆的现实驾驶场景中;以及将融合后的驾驶场景投射到车辆前挡风玻璃中的虚拟画布上。本发明还涉及一种车载显示装置,以及包括该装置的驾驶辅助系统。
