Visible-light and infrared multi-dimensional zoom polarization imaging material evidence search system

Abstract

The invention discloses a quick search system for public security case on-spot material evidences with a visible-light and infrared multi-dimensional zoom polarization imaging detection function, andbelongs to the technical field of multi-spectral multi-dimensional polarization imaging detection. In order to solve problems existing in the prior art, the system comprises an optical detection subsystem, a servo subsystem, an electronics subsystem and a power supply subsystem; the optical detection subsystem is fixedly connected to the servo subsystem and the electronics subsystem, the electronics subsystem receives and processes image information of the optical detection subsystem and then transmits driving signals to the optical detection subsystem and the servo subsystem, and the power supply subsystem is connected with the optical detection subsystem, the servo subsystem and the electronics subsystem for power supply. The system adopts a multi-dimensional detection technology of visible-light polarization and infrared polarization imaging, can be carried on the drone platform to detect a specific area of a complex environment in real time, and a hidden, camouflaged, invisible anddim target can be quickly detected.

Description

technical field [0001] The invention belongs to the technical field of multi-spectral multi-dimensional polarization imaging detection, and relates to a visible light and infrared multi-dimensional zoom polarization imaging evidence search system. Background technique [0002] In the process of modern case detection, the search and extraction of on-site physical evidence is an important content of on-site investigation and the basis for physical evidence inspection. In the investigation of many cases, it is of great significance for us to correctly analyze and judge the case, determine the scope of investigation, obtain case evidence, investigate suspects, and determine the facts of the case. However, the environmental conditions of the scene of the case are often complicated, especially the explosion case, which has the characteristics of a large area and a lot of smoke and dust in the terrain. At present, the use of drones to search for physical evidence on the scene can g...

Problems solved by technology

Although these UAV-borne imaging systems have superior performance, they are still intensity imaging systems, and their F value is too large, which is not suitable for polarization imaging, and there are few researches on related polarization imaging systems
