Abstract

The invention discloses an on-site solid footprint digitalization integrated processing system which comprises an optical balopticon, a CCD camera, a stepping motor, a bracket and a computer; the optical balopticon, the CCD camera and the stepping motor are arranged on the bracket; the optical balopticon is used for irradiating the solid footprint and carrying out the optical coding; the CCD camera is used for collecting an optical coding image; the stepping motor is used for driving the stepping of the optical balopticon and the CCD camera; the computer carries out the digital image analysis to the optical coding image collected by the CCD camera to obtain solid footprint three dimensional point cloud data. The on-site solid footprint digitalization integrated processing system of the invention further comprises a solid footprint three dimensional comparison device and a solid footprint carving and reducing device which can overcome the disadvantages of the traditional gypsum solid footprint, realize the lossless extraction of the solid footprint and provide a more scientific and convenient appraising tool for appraisers to carve and reduce the solid footprint.

Description

technical field [0001] The invention refers to a digital comprehensive processing system for on-site three-dimensional footprints. It is mainly to complete the digital collection of on-site three-dimensional footprint information, three-dimensional comparison of three-dimensional footprints and engraving and restoration of three-dimensional footprints. Background technique [0002] Three-dimensional footprints are the type of traces with the highest rate left on crime scenes, and are one of the most common traces and physical evidence at crime scenes. Three-dimensional footprint inspection and identification can reflect the track of the criminal's crime scene activities and the individual information of the criminal. Therefore, the three-dimensional footprint can provide clues for the investigation and solve the case, and can be used as evidence to expose and confirm the criminal. Police agencies in many countries in the world attach great importance to the research and uti...
