Preferably, in order to ensure that the camera can completely cover the blind area of the vehicle, when the camera in this embodiment is mounted on the vehicle body at the side of the vehicle, the optical axis of the lens of the camera is ensured to be parallel to the ground, and simultaneously, the optical axis of the lens is parallel to the vehicle body measuring surface.
In addition, since the vehicle has both left and right sides, the two cameras are provided on the vehicle body on the left side of the vehicle and on the vehicle body on the right side of the vehicle.
Preferably, the present invention is described by taking a camera mounted on one side of a vehicle as an example: after the camera installation is accomplished, still include:
and step S2, when the vehicle stops, determining an early warning trigger condition according to the first warning line, the second warning line and the image shot by the camera.
Preferably, as shown in fig. 1, the first warning line includes a first one-meter warning line, a first two-meter warning line and a first three-meter warning line. The distance between the first one-meter warning line and the vehicle body on the side of the vehicle is 1 meter, the distance between the first two-meter warning line and the vehicle body on the side of the vehicle is 2 meters, and the distance between the first three-meter warning line and the vehicle body on the side of the vehicle is three meters; the second guard line is 3 meters from the body in front of the vehicle.
As can be seen from fig. 1, the area between the guard line and the vehicle body is generally a dangerous area, that is, when an object is within the area, it is considered that a warning is required to the driver. Therefore, the corresponding early warning triggering condition is set. Namely: when the target is obtained, whether the position where the target is located falls into the dangerous area or not is detected to judge whether early warning is triggered or not.
Preferably, when the early warning judgment condition is set, as shown in fig. 3, the method specifically includes:

Preferably, when the warning line determination function is set, an image captured by the camera is obtained first, and pixel coordinate values of each warning line and a calibration point on each warning line are extracted from the image, and then a corresponding warning line early warning determination function is obtained according to the pixel coordinate indication of the calibration point on each warning line.
Specifically, for the second cordline function: the first index point F1 and the second index point F2 are set on the second warning line. The pixel coordinate values of the first calibration point F1 and the second calibration point F2 can be obtained according to the image shot by the camera, and then the first warning line early warning judgment function is determined according to the pixel coordinate value of the first calibration point F1 and the pixel coordinate value of the second calibration point F2.

Preferably, the embodiment also sets the early warning level according to the distance between the target and the vehicle body. As shown in fig. 1, for example: when the region between the first meter warning line and the vehicle body is set, the danger coefficient is considered to be the highest, the early warning level is 1 level, and corresponding early warning levels are set in sequence in the same way.

Wherein the first size is 300 x 300.
Wherein the pixel coordinate value of the target is equal to the pixel coordinate value of the center of the lower edge of the target position. That is, the midpoint of the lower edge of the target position is located at the position of the target landing point.
Preferably, the objects in this embodiment include pedestrians and non-motor vehicles.
And step S32, substituting the pixel coordinate values of the target into each warning line pre-tightening judgment function to judge whether to trigger early warning.
Specifically, for example, when the target is between the second warning line and the vehicle body, it is considered that the warning is triggered. Meanwhile, the early warning level can be judged by substituting the pixel coordinate point of the target in the image into the result value of each warning line function. That is, the distance of the target with respect to the vehicle body is judged to determine the warning level.
