Abstract

The invention discloses an image restoration method based on a VIN image acquisition device, and relates to the technical field of image acquisition and processing. The present invention constructs an image acquisition device including a structured laser generator, a structured laser camera, and a visible light camera, and utilizes the conversion relationship between the spatial three-dimensional coordinates of any point on the thin line, the pixel coordinates of the structured laser image, and the pixel coordinates of the visible light image, The shape parameters of the surface to be measured in the structured laser image are obtained, and the visible light image is geometrically transformed and surface unfolded using the shape parameters, and finally a restored image including a scale is obtained. The restored image of the vehicle identification number obtained by the present invention has a known spatial resolution, so the restored image can be printed out and compared with the real object or paper rubbing material for 1:1 comparison.

Description

technical field [0001] The invention relates to the technical field of image acquisition and processing, in particular to an image restoration method based on a VIN image acquisition device. Background technique [0002] Vehicle Identification Number, abbreviated as VIN (Vehicle Identification Number), is a set of characters specified by the car manufacturer to identify a car. It is like a person's ID card and has the unique identification of a car in the world. sex. According to the provisions of GB7258-2017, the technical conditions for motor vehicle operation safety: "Automobiles, motorcycles, and trailers should have unique vehicle identification codes, and their content and composition should comply with the provisions of GB16735; at least one vehicle identification code should be engraved on the frame. (A motor vehicle without a frame is the main load-bearing and non-removable part of the body) on the part that can prevent corrosion and wear; the engraved vehicle iden...
