The invention discloses an automatic vehicle door unlocking method based on artificial intelligence. The method comprises the steps of enabling a sensor to detect the distance between a pedestrian near a vehicle and the vehicle, judging whether the pedestrian possibly has a riding intention, and triggering a camera to collect a target pedestrian image near a vehicle door; analyzing the target pedestrian image to obtain three-dimensional key point coordinates of the target pedestrian, a judgment result of whether the target pedestrian inclines forwards or not and a judgment result of whether the target pedestrian stretches out of the hand or not; calculating posture change parameters of the target pedestrian according to the three-dimensional key point coordinates if the upper body forwardleaning and hand stretching behaviors exist; enabling the posture change parameters at the same moment to form a parameter vector, enabling the parameter vector to form a riding trend parameter tensoraccording to timestamps, inputting the riding trend parameter tensor into a riding intention prediction time sequence analysis model to be analyzed, outputing a riding intention prediction result ofthe target pedestrian, and if the riding intention exists, controlling a vehicle door to be automatically unlocked. According to the invention, the vehicle door can be controlled to be automatically unlocked.

    本发明公开了一种基于人工智能的车门自动解锁方法。包括:传感器检测车辆附近行人与车辆的距离,则判断行人是否可能有乘车意图,触发摄像头采集车门附近的目标行人图像;对目标行人图像进行分析,得到目标行人的三维关键点坐标、目标行人是否存在上身前倾的判断结果、目标行人是否存在伸手行为的判断结果;若存在上身前倾和伸手行为,根据三维关键点坐标计算目标行人的姿势变化参数;将同一时刻的姿势变化参数组成参数向量,并将参数向量按照时间戳组成乘车趋势参数张量,输入乘车意图预测时序分析模型进行分析,输出目标行人的乘车意图预测结果,若有乘车意图,控制车门自动解锁。利用本发明,可以控制车门自动解锁。
