Suspicious Scene Footprint Capture System

Introduction

This system performs well in imaging poor photography footprints like under confusing background (terrazzo, marble), non-smooth objects and high reflectivity etc.

Features

● Poor footprints extraction: Footprints on the surface of complex patterns, on highly reflective surfaces, on matte grainy surfaces and obliquely visible footprints

● Optical scanning imaging without touching the traces or spoiling the scene

● Background light separation imaging technology greatly suppresses the objects background information and improves the signal-to-noise ratio of the footprint image

● The residual traces on the ground after electrostatic film adsorption can still be scanned and extracted, meanwhile the contrast is not inferior to the initial state

● Line scanning imaging avoids the uneven illumination which can be caused by lighting source in conventional pictures

● Optical scanning imaging method avoids tilt distortion and blur produced by manual shooting, and ensures the true shape is reflected in every part of the image

● According to the different needs of dust footprint, water footprint, blood footprint etc, various collection modes are built in. Users only need to make simple choices based on the scene conditions, the system automatically allocates light and collects valuable traces images with one click and saves automatically

● Completely closed optical circuit, shielding external light interference; No jitter, no interference from human factors

● The host adopts multi-layer composite aviation grade aluminum alloy, which is portable, beautiful and durable.

● Microsoft surface tablet is used as the handheld control terminal to be separated from the host, it works by wireless remote control for easier operation. Tablet computer control terminal can also be used for scene shooting/recording, scene drawing and noting etc. to improve the efficiency of on-site survey

● Equipped with professional scene footprint exploration light source, can quickly search the scene and capture relevant footprints

Technical Parameter

● The shell is made of aviation grade aluminum alloy, which is light and heat dissipation. The shell surface is provided with footprint area indicating labels.

● More than 10 megapixels
