Description
Technical Field
The invention relates to the field of vehicle view acquisition devices, in particular to a TOF vehicle full view acquisition device and method.
Background
Tof (time of flight) technology provides a way to determine the distance of an object from the emitting end by the elapsed time of directing the emitted light and receiving the signal it reflects back. When the ranging light is emitted in a dot-matrix scanning mode, the high-frequency TOF module can even return to a point cloud image of an imaging plane. The area behind the front interior mirror of a vehicle, which is used by many car shops for placing various sensors, such as an auto-induction raindrop sensor, etc. This mounting position is closest to the height of the driver's view. When the following distance is too close, the view of the driver is blocked by the front vehicle, and at the moment, the potential risk of driving is generated as long as the driver does not know the road condition in front. Experienced drivers often adopt a mode that one side of the driver is close to the edge of the road, the visible area of the driver can be enlarged in the mode, but due to the fact that the close sides are too close, the situations of scratch and the like are easy to cause. In the prior art, as mentioned in the CN201420869793.6 patent, attention is paid to the extension of the rear view field of the rearview mirror, such as blind zone detection of the field of view, scratch prevention, and the like. However, none of the prior art concerns how to enhance and extend the forward field of view of the driver. And the existing patents are more focused on the effect of using a camera to replace a rearview mirror. Even if a part of forward vision can be obtained due to problems of installation position and the like, the forward vision can be realized only by using a fisheye camera with a very large angle, and the larger the angle of the fisheye lens is, the more obvious distortion is, and the closer the fisheye lens is to the edge of the vision, the more the details are completely overlapped and cannot be distinguished.
