Investigation method and device for scene material evidence information investigation vehicle

Abstract

The invention discloses an investigation method and an investigation device for a scene material evidence information investigation vehicle, and relates to an investigation vehicle. The problem that the conventional investigation vehicle only can be used for searching investigation, and cannot be used for scene detection is solved. A searching device of the investigation vehicle comprises the conventional ordinary camera, a hard light source, an ultraviolet and infrared digital camera system capable of revealing potential traces, a multi-band light source for wide-range searching and a dual-wavelength laser developer for completely searching for scene biogenic traces and the potential traces, so that the aim of completely searching for scene suspected information can be achieved. In addition, an image processing system for extracting and processing a suspected mailbox found on the scene and a master control platform are arranged on the investigation vehicle, an electronic document for scene investigation results is established, and document information is directly uploaded to a command post of a public security system, and is compared with information in a data information library of the public security system, and suspect information is quickly determined, and is uploaded to the command post of the public security system to provide help for the quick detection of a criminal case.

Description

technical field [0001] The invention relates to an inspection vehicle, in particular to an inspection method and a device thereof for an on-site physical evidence information inspection vehicle used at a criminal case scene. Background technique [0002] The main function of the current criminal investigation vehicle is to carry relevant investigation equipment with the vehicle, search and investigate the scene of the criminal case in time, and extract the necessary physical evidence. It will affect the timeliness of the on-site judgment of the surveyors. If a new problem is found in the test, it is necessary to drive to the scene of the crime to collect evidence, which affects the quality and efficiency of case handling. [0003] In addition, most of the existing investigation vehicles are in the form of ordinary strong light sources attached to the investigation boxes. With the development of science and technology, the potential traces left by criminal suspects are chara...

Problems solved by technology

[0002] The main function of the current criminal investigation vehicle is to carry relevant investigation equipment with the vehicle, search and investigate the scene of the criminal case in time, and extract the necessary physical evidence. It will affect the timeliness of the on-site judgment of the surveyors

If new problems are found in the inspection, it is necessary to drive to the scene of the crime to collect evidence, which affects the quality and efficiency of case handling

[0003] In addition, most of the existing investigation vehicles are in the form of ordinary strong light sources attached to the investigation boxes. With the development of science and technology, the potential traces left by criminal suspects are characterized by diversity and complexity. There will be restrictions in obtaining evidence, especially the search for potential traces (poor visibility of potential traces by the human eye) is difficult. Obviously, the existing inspection vehicles can no longer meet the requirements of on-site investigation and physical evidence technology development
