A document surface three-dimensional topography processing method based on linear laser three-dimensional scanning

Abstract

The application discloses a kind of based on line laser three-dimensional scanning document surface three-dimensional topography processing method, specifically related to three-dimensional surface processing technical field, including obtaining disputed handwriting area in the original to be detected, and with the outer boundary of disputed handwriting area, two sides adjacent paper area and non-disputed handwriting area of same page are extracted outward, form detection area group, output area result;By intelligent sensing system according to area result, keep the original to be detected in natural flat state, and execute line laser scanning to detection area group according to fixed line position sequence, reconstruct the first surface profile of each area, output first profile group;By executing line laser three-dimensional scanning to the disputed area of document surface respectively in natural flat state and controlled release shape state, and combined with the contemporaneous release shape change of two sides adjacent paper area and non-disputed handwriting area of same page, separate checking is carried out, and historical compression mark after being weakened by pressure is re-exposed and extracted.
