The invention relates to a vehicle door collision early warning method and device, a medium and electronic equipment. The vehicle door collision early warning method comprises the steps that a gear switching action on a driving side is responded, a vehicle door locking control signal is sent to lock a vehicle door, and a vehicle AVM system picture output signal is sent; an AVM panorama of the outer side of a vehicle body is collected in real time in the vehicle door locking state, and a vehicle door outer side picture with the distance relative to the real vehicle position meeting the preset detection range is obtained; preprocessing the AVM panorama to obtain a first view and a second view which respectively display the outer side conditions of the left and right vehicle doors; respectively calculating the gray value variation of two adjacent images of the first view and the second view, comparing the gray value variation with a safety threshold value, judging whether obstacles appear on the left side and the right side of the vehicle body or not, and updating the vehicle door state identification in the corresponding direction according to a judgment result; when it is detected that the passenger in the vehicle opens any vehicle door, the vehicle door state identification in the corresponding direction is read based on the direction of the opened vehicle door, and an alarm or vehicle door unlocking signal is triggered according to the vehicle door state displayed by the identification.
本发明涉及一种车门碰撞预警方法及装置、介质和电子设备,包括响应驾驶侧的档位切换动作,发出车门锁定控制信号锁紧车门,发出车机AVM系统出图信号;在车门紧锁状态下实时采集车身外侧的AVM全景图,获得相对实车位置的距离符合预设检测范围的车门外侧画面;通过对AVM全景图的预处理,获得分别显示左、右两侧车门外侧状况的第一、第二视图;分别计算第一、第二视图的其相邻两张图像的灰度值变化量,比较该灰度值变化量与安全阈值的大小,判断车身左右两侧是否出现障碍物,并根据判断结果更新相应方位的车门状态标识;当检测到车内乘客开启任一车门时,基于开启的车门方位读取相应方位车门状态标识,并根据标识显示的车门状态触发报警或车门解锁信号。
