Monocular vision distance measurement method and device for random scene under rapid movement

The invention provides a monocular vision distance measurement method and device for random scene under rapid movement, and relates to the field of electrical data processing. The method comprises thefollowing steps of acquiring a license plate specification of an adjacent vehicle when the width of an image of the adjacent vehicle in a camera is greater than a safety threshold, and acquiring a shooting angle; and acquiring a vehicle distance of the adjacent vehicle in a preset vehicle distance database according to the license plate specification and the shooting angle. According to the method and the device, the real vehicle distance between the adjacent vehicle and the vehicle is obtained through calculation, so that the misjudgment of a driver on the vehicle distance is reduced, the personal safety of the driver is ensured, and meanwhile, due to the fact that the distance information of the adjacent vehicle is measured and recorded, the basis can also be provided for the responsibility determination of a t
