步骤S302，若未检测到开启转向灯的转向信号，则在所述图像帧的第一预设区域内检测到所述目标对象时，控制所述汽车的报警屏和声光报警器进行报警；
在本申请实施例中，预先在直线行驶时分别标定上述右侧摄像头和左侧摄像头拍摄的画面中对应的汽车的危险区域并设定为第一预设区域。当未检测到开启右转向灯的右转向信号和未检测到开启左转向灯的左转向信号，且在上述右侧摄像头或左侧摄像头拍摄的画面中第一预设区域中检测到目标对象时，控制上述报警屏和声光报警器进行报警。
步骤S303，若检测到开启转向灯的转向信号，则在所述图像帧的第二预设区域内检测到所述目标对象时，控制所述汽车的报警屏和声光报警器进行报警。
在本申请实施例中，若检测到开启右转向灯的右转向信号，即表示汽车将要向右转或正在右转；若检测到开启左转向灯的左转向信号，即表示汽车将要向左转或正在左转。预先在右侧摄像头拍摄的画面中标定在检测到右转向信号时对应汽车的危险区域设定为第二预设区域；预先在左侧摄像头拍摄的画面中标定在检测到左转向信号时对应汽车的危险区域设定为第二预设区域，当检测到开启右转向灯的右转向信号或开启左转向信号，且在右侧摄像头拍摄的的第二预设区域中或左侧摄像头拍摄的第二预设区域中检测到目标对象时，控制上述报警屏和声光报警器进行报警。预设上述第二预设区域的范围大于上述第一预设区域。即将在将要转弯或正在转弯时把目标对象所在的危险范围比汽车在直线行驶时的危险范围进行了扩大，可在汽车转弯时通过将报警的距离增加，从而减少在转弯时容易发生事故的概率。
在一个实施例中，当所述图像帧中存在目标对象时，通过转向角传感器检测所述汽车方向盘的转动角度；其中，所述转向角传感器设置在所述汽车的方向盘上。当上述图像帧中存在目标对象时，通过获取转向角传感器检测汽车方向盘的转动角度，根据转动角度可以判断汽车处于直行状态、转弯状态或者其它行使状态。上述转动角度传感器可以是汽车本身自带的转动角度传感器，也可以是预设置在上述汽车的方向盘上的转动角度传感器。
在一个实施例中，若所述转动角度小于预设转动角度，则在所述图像帧的第一预设区域内检测到所述目标对象时，控制所述汽车的报警屏和声光报警器进行报警。预先设定转动角度，当获取汽车当前的转动角度小于预设转动角度，即表示汽车是接近直线行使的，预先将上述摄像头拍摄的画面中标定在接近直线行走时汽车的危险区域设定为第一预设区域。当所述转动角度小于预设转动角度，且在第一预设区域中检测到目标对象时，控制上述报警屏和声光报警器进行报警。
在一个实施例中，若所述转动角度大于或等于所述预设转动角度，则在所述图像帧的第二预设区域内检测到所述目标对象时，控制所述汽车的报警屏和声光报警器进行报警。当获取汽车当前的转动角度大于或等于预设转动角度，即表示汽车是转弯行使的，预先将上述右侧摄像头和左侧摄像头拍摄的画面中标定汽车在此时的危险区域设定为第二预设区域。当所述转动角度大于或等于所述预设转动角度，在第二预设区域中检测到目标对象时，控制上述报警屏和声光报警器进行报警。预设上述第二预设区域的范围大于上述第一预设区域。可根据汽车是行驶状态预设不同的报警区域，将在汽车转弯时把目标对象所在的危险范围相对于汽车在直线行驶时的危险范围进行了扩大，可在汽车转弯时通过将报警的距离增加，从而减少在转弯时容易发生事故的概率。
由此可见，在本申请实施例中，一方面，由于可在右侧摄像头和/或左侧摄像头拍摄汽车左侧和/或右侧的盲区中检测到目标对象时，控制安装在汽车驾驶室中的报警屏进行报警可以提醒驾驶员注意行人，可控制安装在汽车外部的声光报警器进行报警提醒行人注意车距，从而提高了汽车的行车安全；另一方面，可以根据汽车的右转向灯的右转向信号预设不同的报警区域，在汽车右转弯时报警的距离增加，从而减少在转弯时容易发生事故的概率。
