Laser footprint scanner is a set of footprint image acquisition system specially designed for flat surface on site. Summarize the various difficult footprints in the actual scene of case handling, such as the footprints submerged by the background pattern, the footprints on the high reflective surface, and many footprints that can be seen but can not be photographed. Using unique technology and high definition imported imaging components, most of the common difficult footprints can be cleared. Clear presentation.
Performance characteristics
Difficult Footprint Extraction: Footprints on Complex Patterned Surface; Footprints on Highly Reflective Surface; Footprints on Dumb Particle Sensitive Surface; Only Visible Footprints can be Observed Tiltingly.
Non-destructive: Optical scanning imaging mode, no contact with traces, no damage to the scene.
High signal-to-noise ratio: The background light separation imaging technology can greatly suppress the background information of the object and improve the signal-to-noise ratio of the footprint image.
High sensitivity: The residual traces on the ground after electrostatic membrane adsorption can still be scanned and extracted, and the contrast is still not inferior to the extraction of the initial state.
Uniformity: Linear scanning imaging avoids the uneven illumination caused by illumination source problems in conventional photographs.
Deformation-free: Optical scanning imaging method, avoiding oblique distortion and blurring caused by manual shooting, ensures that every part of the image reflects the true shape of the trace.
Automation: According to the needs of dust footprint, water footprint, blood footprint and other different situations, a variety of acquisition modes are built-in. Users only need to make simple choices according to the situation on the spot, the system automatically distributes light, and collects and saves the valuable trace images by one key.
Specialization: Scanning pictures are automatically superimposed on all sides of the full-length scale, no need to add physical scale; provide floating measuring scale tools to facilitate access to professional data such as shoe size, height, age; provide convenient binary image tools, easy to generate images required by professional library.
Standardization: No shooting experience is required. Anyone can extract the same image quality and specifications for the same trace.
All-weather: Working day and night.
High stability: fully enclosed optical path, shielding external light interference; no jitter, not interfered by human factors.
High Strength Fuselage: The main engine adopts multi-layer composite integrated all-engineering plastic fuselage, which is portable, beautiful and durable.
Separated operation: Tablet computer as a handheld control terminal is separated from the host computer and operates in a wireless remote control mode, which makes the operation easier.
Multipurpose terminal: Tablet computer control terminal can do scene shooting/recording, field drawing, recording and other work to improve the efficiency of prospecting.
