According to the fusion parking method and device, time synchronization between an MCU and an SOC chip is achieved through a hard wire UART, and time is marked on key information such as parking space data and obstacle data recognized by a camera and parking space data and obstacle data recognized by an ultrasonic sensor or a radar; and when the time sources are judged to be the same time source, fusion is carried out and displayed at the vehicle-mounted terminal for a user to select a required parking space, and then path planning is carried out according to the parking space selected by the user and parking is executed. According to the invention, the time error from the sensor sampling moment to the control decision moment can be reduced, and the accuracy of parking space and obstacle fusion is improved.
本发明公开一种融合泊车方法及装置,通过硬线UART实现MCU和SOC芯片间的时间同步,并对摄像头识别的车位数据和障碍物数据、超声波传感器或雷达识别的车位数据和障碍物数据等关键信息标注时间,在判断为同一时间源时进行融合并显示在车机端以供用户选择所需车位,再根据用户选择的车位进行路径规划并执行泊车。本发明能减少从传感器采样时刻到控制决策时刻的时间误差,提高车位及障碍物融合的精确度。
