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 method comprises the followingsteps: constructing an image acquisition device comprising a structural laser generator, a structural laser camera and a visible light camera, and obtaining profile parameters of a to-be-measured surface in a structural laser image by utilizing a conversion relationship among a spatial three-dimensional coordinate of any point on a fine line, a structural laser image pixel coordinate and a visiblelight image pixel coordinate; and performing geometric transformation and curved surface expansion on the visible light image by utilizing the profile parameters, and finally obtaining a restored image containing a proportional scale. The vehicle identification code restored image obtained by the invention has a known spatial resolution, so that the restored image can be printed and compared witha real object or a paper rubbing material in a ratio of 1:1.

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...
