Pressure sensing light and shadow imaging system and imaging method thereof

Abstract

The invention provides a pressure sensing light and shadow imaging system and an imaging method thereof. The pressure sensing light and shadow imaging system comprises bearing media, a sensing surface, light and shadow media, a light pool, a light and shadow system and an imaging surface. The bearing media are arranged at the uppermost end of the pressure sensing light and shadow imaging system. The lower portion of the bearing media makes contact with the sensing surface. The lower portion of the sensing surface is closely combined with the upper surface of the light pool provided with the light and shadow media. The imaging surface is arranged below the light pool. Textured substances to be imaged are placed on the upper surface of the bearing media. The bearing media transmit borne pressure to the sensing surface. The sensing surface senses pressure distribution of the textured substances. Light rays in the light pool are reflected by the sensing surface to reflect out the contact tightness between the sensing surface and the bearing media and to generate a pressure distribution image of the textured substances. The sensing surface projects the generated pressure distribution image of the textured substances to the imaging surface. The pressure sensing light and shadow imaging system can be used for forming the contact pressure image of the textured substances and enabling the formed image to be capable of reflecting out the contact pressure distribution, the image of the textured substances and the pressed sequence.

Description

technical field [0001] The invention designs light and shadow imaging technology, and in particular relates to a system and an imaging method using pressure-sensitive light and shadow imaging. Background technique [0002] Existing imaging systems all use the light reflected by the object to form images, and the images are two-dimensional, and the pressure cannot be observed on the displayed planar photos. The pressure distribution of texture materials, such as the pressure distribution of footprint images, is of great significance to criminal investigation work. [0003] With the development of existing technology, the development of handwriting electronic imaging system is getting higher and higher. However, the existing technology can only reflect handwriting to electronic equipment, and the pressure distribution and stroke order of written writing cannot be queried and archived. . In handwriting comparison systems and handwriting query systems, stroke order and pressur...
