Intelligent trace material evidence searching and finding shooting instrument

Abstract

The invention discloses an intelligent trace material evidence searching and finding shooting instrument. The intelligent trace material evidence searching and finding shooting instrument comprises ahousing, a photographing mechanism embedded in the end surface of the housing, a glancing light lamp, a polarized light lamp and a light source lamp group of various different wave lengths, wherein the glancing light lamp, the polarized light lamp and the light source lamp group are arranged on the open side of the housing; an oriented reflection mechanism is arranged between the photographing mechanism and the light source lamp group; a light filter is inserted in one side of the housing through an inserting rod, and is arranged below an ultraviolet lens; a threaded pipe is fixedly mounted atthe middle part of a focusing rotating disk; a fan-shaped blue light piece is arranged on the inner side of the focusing rotating disk; and the fan-shaped blue light piece is driven by the focusing rotating disk to be rotatably arranged in a position at the rear part of a camera for conventional shooting, on the rear side of the photographing structure. According to the intelligent trace materialevidence searching and finding shooting instrument disclosed by the invention, during fingerprint and trace acquisition, the combination of various light sources is started for supplementing light, and the light filter and blue light pieces are used cooperatively, so that the camera on the rear side of the photographing mechanism can photograph traces including clear fingerprints or handprints and the like; and the intelligent trace material evidence searching and finding shooting instrument is higher in integration, high in comprehensiveness and more convenient to use.

Description

technical field [0001] The invention belongs to the technical field of police equipment, and in particular relates to an intelligent trace material evidence search and discovery camera. Background technique [0002] With the rapid development of communication technology, the products derived from it are applied in all walks of life, for example, the public security personnel can use the fingerprint collection device and so on in the process of handling cases. Fingerprints are widely used in public security work as the "leading piece of evidence". The National Criminal Investigation Fingerprint Database is the project with the largest national investment, the longest continuous investment period and the widest network coverage. Judging from the effect of public security work such as solving crimes and chasing escapes, the criminal investigation fingerprint database has not yet played its due role. Criminals generally leave fingerprints at the scene of the crime, so fingerpr...

Problems solved by technology

[0003] At present, the fingerprint display technology in the market is one-way function, resulting in complicated equipment, not convenient to use, and not clear enough to capture fingerprints and other traces, so further design of fingerprint processing equipment is required
