Processing method of pressure-sensitive light and shadow imaging system and formed footprint image

摘要

The pressure-sensitive light and shadow imaging system is comprised of carrier medium (1), inductive surface (2), photo source (3), photocell (5) and imaging surface (6), wherein the said carrier medium (1) is set on the top of the pressure-sensitive light and shadow imaging system, and the lower end contacts with the inductive surface (2) whose lower end is closely integrated with upper surface of the photocell (5). The imaging surface (6) is set underneath the photocell (5). Texture substance (7) contacts the carrier medium (1), which can form the pressure-sensitive image. The image can reflect the pressure distribution of the substance and compression sequence. With the processing method of footprint image formed by such pressure-sensitive light and shadow imaging system, several single-frame footprint images are processed as a complete footprint image containing all footprint features, which can eliminate background noise.

1. A pressure-sensitive light and shadow imaging system, including a carrier medium bearing pressure of a texture substance, a photocell, a light source, an inductive surface and an imaging surface, characterized in that the carrier medium is set as an uppermost layer of the pressure-sensitive light and shadow imaging system, the carrier medium is a plane substance comprising a synthetic fiber layer and an elastic composite layer; a lower surface of the carrier medium contacts with the inductive surface; the inductive surface is thicker than the elastic composite layer, a lower surface of the inductive surface closely contacts with an upper surface of the photocell; the imaging surface is set underneath the pressure-sensitive light and shadow imaging system, and the light source is set on at least one side of the photocell.
