Description
Technical field
The present invention relates to the material evidence camera technique of forensic science field evidence obtaining, refer in particular to a kind of forensic science spheroid thing
The photographic means of card surface latent evidence obtaining and photographic means thereof.
Background technology
Material evidence camera installation (containing material evidence camera, photographing unit light source etc.) is that material evidence is carried out by public security organs, procuratorial organs and people's court, Si Deng department
Evidence obtaining is with the visual plant carrying out trace identification further.Vestige on complex geometry object can be taken by this camera installation
Card, for solving a case, decide on a verdict offer foundation, therefore the trial work of the case such as criminal, civil is played important by material evidence camera installation
Effect.
Photographing unit is the photo being difficult to take the photograph into human viewable for vestige available light potential on complex geometry object,
Special material evidence light source have to be equipped with when the vestige on complex geometry object being collected evidence accordingly, as material evidence camera irradiate
Device, finger mark vestige potential on complex geometry object especially spheroid material evidence is formed under the irradiation of material evidence light irradiation device strongly
Reflective speckle, reflective speckle have a strong impact on finger mark streakline feature performance, cause to this potential finger mark verification of traces identify difficulty.
Existing material evidence light irradiation device is the structure separated with photographing unit, if in indoor use material evidence camera,
Typically material evidence light irradiation device is arranged on (gimbals as on copy stand) on a support, makes finger mark etc. by best angle
Material evidence clearly manifests, and then this material evidence is taken a picture by staff；If in flagrant delict using material evidence camera, owing to making
The environment at case scene is the most poor, can only be guided and supported material evidence light irradiation device by operator, connect power supply, make by best angle
The material evidences such as finger mark clearly manifest, and are then shot this material evidence by another operator.The structure of this light irradiation device is deposited
At shortcomings:
1, without connecting the buckle of photographing unit leading portion camera lens, therefore, it can not connect together uses with photographing unit, answers at the scene
Light source irradiation position, angle cannot be accurately positioned under heterocycle border, in-convenience in use, need several operator to collect evidence, have impact on
Evidence obtaining efficiency；
2, without internal battery, need external power supply to work, it is impossible to adapt to on-the-spot complicated working environment, use limitation
Property is big；
3, the light that light irradiation device irradiates forms strong reflective speckle, the serious shadow of reflective speckle on spheroid material evidence surface
The feature performance of snap plating line, thus affects the definition that imaging shows, the inefficient and quality of collecting evidence of causing collecting evidence can not
Lean on, directly affects working quality of case handling.
