The invention discloses an early warning method, device and equipment for vehicle meeting at a mountain road curve and a medium, and the method comprises the steps: obtaining a first moving target set in a visual field based on a vehicle camera; at least one metal panel is arranged at the bend opening; transmitting a microwave signal based on the millimeter wave radar of the vehicle, receiving a microwave reflection signal, and analyzing a second moving target set; wherein the emitted microwave signal is reflected to a target opposite to the curve through the at least one metal panel, then is reflected to the at least one metal panel through the target opposite to the curve, and finally returns to the millimeter wave radar of the vehicle; and according to the first moving target set and the second moving target set, obtaining a hyper-visual field moving target set. According to the method, only at least one metal panel needs to be arranged at the bend opening, the second moving target set is obtained based on the millimeter wave radar of the vehicle, then the first moving target set is obtained according to the camera of the vehicle, the hyper-visual-field moving target set is obtained, and the moving condition of the target in the opposite direction of the bend can be effectively perceived.
本发明公开了一种山区公路弯道会车的预警方法、装置、设备及介质,该方法包括:基于自车摄像头,获取视野内第一运动目标集合;在弯道口设置至少一块金属面板;基于自车毫米波雷达发射微波信号,并接收微波反射信号,解析出第二运动目标集合;其中,发射的微波信号经所设置的至少一块金属面板反射至弯道对向的目标,再由弯道对向的目标反射至所设置的至少一块金属面板,最后返回自车毫米波雷达;根据第一和第二运动目标集合,得到超视野运动目标集合。本发明仅需要在弯道口设置至少一块金属面板,基于自车毫米波雷达获取第二运动目标集合,再根据自车摄像头获取第一运动目标集合,得到超视野运动目标集合,可以有效感知弯道对向的目标运动情况。
