In order to realize the acquisition of a driving image with wide shooting range and high definition, the invention provides an image acquisition method based on double lenses, as shown in fig. 2, which specifically comprises the following steps:
s100, receiving a short-focus image acquired by the short-focus lens;

s400, fusing the short-focus image and the long-focus image, and displaying the corresponding fused image on a screen of the automobile data recorder.
In this embodiment, image acquisition is performed at the same time through the short-focus lens and the long-focus lens, where the short-focus lens directly performs image acquisition on an area in a horizontal view angle in front of the vehicle to obtain a short-focus image, and when the positions of the long-focus lens and the short-focus lens are relatively fixed, the long-focus lens can always only capture a small part of the short-focus image at the same time, so in this embodiment, the capturing range of the long-focus lens is adjusted through the reflection mechanism.
Specifically, the user may manually input an area setting instruction to adjust the shooting range of the telephoto lens, or default trigger the preset area setting instruction when the driving recorder is started, the user may flexibly change the area setting instruction later according to the requirement, after receiving the area setting instruction, the control system of the driving recorder responds to the instruction, controls the reflection mechanism to reflect the light of the target area in a corresponding working state, that is, different working states of the reflection mechanism, such as a reflection angle, a movement parameter, and the like, correspond to different target areas, and guides the light of the target area into the telephoto lens through the reflection mechanism to collect the light, so as to effectively expand the shooting range of the telephoto lens, so that the telephoto lens can collect the telephoto image of the target area larger than the self field of view, and further fuse the target area image with higher definition, that is, the telephoto image and the short-focus image, and display the fused image with wide shooting range and high definition on the driving recorder.

As shown in fig. 5 and fig. 6, in an application embodiment, a peripheral large rectangular area in a captured live-action image is a field of view of a short-focus lens, that is, a range of the short-focus image, and at this time, a target area may be set to be any area in the short-focus lens under a condition that a vertical field angle of a long-focus lens is satisfied, that is, three dark-color block areas in fig. 5 correspond to three target areas in different positions respectively, so that a user may implement flexible and convenient target area setting in a manner of, for example, clicking or touch, etc., to implement discontinuous wide-range image acquisition, thereby being convenient for performing targeted shooting on a certain region of interest, and saving system power consumption as much as possible.
In one embodiment, the adjusting the reflecting mirror in the reflecting mechanism to the target reflecting angle specifically includes:

In one embodiment, the adjusting the reflecting mirror in the reflecting mechanism to the target reflecting angle specifically includes:
and outputting a corresponding voltage signal to the reflector combination according to the target reflection angle, and controlling a reflector with the target reflection angle in the reflector combination to be electrified to form specular reflection.

Further, the self-adaptive adjustment of the reflection angle can be performed on the appointed shooting target, so that the shooting target is always positioned in the center of a picture, accurate target shooting is realized, the shooting area of the vehicle speed and the long focus lens is firstly obtained, then the distance of the next image, which is the next frame of image, is predicted according to the vehicle speed, the compensation angle is obtained according to the distance of the next image, which is the distance of the next image, and the angle change between the shooting targets, is calculated, the rotation of the reflecting mirror is controlled to compensate the shooting angle, then whether the shooting target is positioned in the center of the picture is judged, the compensation amount is corrected by means of a Kaler Ma Lvbo and the like to adjust the position of the reflecting mirror, the continuous judgment and the angle compensation are continuously performed, and the self-adaptive rotation adjustment of the shooting area is realized until the compensation angle exceeds the maximum rotation angle.
