Problems solved by technology

However, either way, there are varying degrees of limitations
The text description is not intuitive, and it is difficult to correctly grasp the real situation on the spot
Although photos can make up for some intuitive on-site information that is missing in text descriptions, the information is static, and important traces and physical evidence on the scene cannot be observed from various angles
3D scanning generates a three-dimensional space. Objects or evidence on the scene can be observed from different angles, but it can only be observed and cannot be operated. The traces and evidence that need to be discovered by equipment cannot be seen. Everything in the three-dimensional space is static and cannot be seen. operate
However, based on the traditional VR scene construction technology, it takes more than one month to build any criminal case scene, which cannot meet the actual criminal investigation needs that must be solved as soon as possible.

Embodiment 1

[0043] This embodiment proposes a multi-person collaborative investigation method based on VR technology. The first step is to build a virtual criminal scene based on VR technology, including on-site 3D scanning, trace evidence extraction, virtual scene construction, trace evidence copy, and virtual survey. Through rapid scanning and modeling, the construction time of traditional VR scenes is greatly shortened, and the crime simulation scene construction can be completed within a day or even a few hours. Specifically:

[0044] (1) On-site 3D scanning: Using professional 3D on-site scanning equipment for criminal case investigation, the criminal scene and all objects in it can be scanned within a few minutes at the fastest. The scanning range includes: 1) Central scene. Scan each area of ​​the center site and each direction of each area and each object and facility in all areas; 2) Places with exploration clues. Scan every direction of the area where the site where there are ex...

Embodiment 2

[0066] According to the collaborative reconnaissance system, this embodiment proposes the implementation of the reconnaissance system, which is used to further explain the composition and function of the reconnaissance system, specifically as image 3 as shown,

[0067] 1. On-site 3D scanning: use criminal investigation 3D scanning equipment to scan the crime scene completely. Through the public security private network or 5G network, the on-site scanning data is transmitted to the on-site rapid modeling platform server in real time. The scanning range includes the central scene, places with exploration clues and peripheral scenes, as described in Example 1 for details.

[0068] 2. On-site trace extraction: Use criminal investigation trace extraction equipment to extract all traces at the scene of the crime, including obvious and hidden traces, and record the location and shape of each trace at the scene with voice and photos. Through the public security private network or 5...

Abstract

The invention discloses a multi-person cooperative investigation method and investigation system based on a VR technology. The method comprises the steps that a virtual crime scene is built; multiplepersons enter the virtual crime scene; all people carry out collaborative investigation according to field investigation specifications; in the virtual crime scene, for the extracted trace material evidences, voice is used for field recording, the extracted material evidences are described, and the situation of the crime scene is mastered step by step; and the case is analyzed, studied and judgedby integrating the on-site investigation result, and the suspect portrait and the behavior track of the suspect portrait are described. According to the invention, the threshold that criminal case investigation is limited to an actual site is broken through, a new cross-space collaborative investigation mode is created, an actual combat system for rapid modeling of a criminal scene and cross-spacecase analysis, research and judgment and collaborative investigation is realized, and the actual demand of rapid criminal case investigation in the criminal investigation field is met.

Description

technical field [0001] The present invention relates to the field of criminal investigation, in particular, to a multi-person collaborative investigation method and investigation system based on VR technology. Background technique [0002] The on-site display of criminal cases has changed from text descriptions, photos to videos, and then to 3D scanning. Great progress has been made in both form and content. The display forms are constantly enriched and the display content is deepened, providing effective means for case analysis and judgment. However, either way, there are varying degrees of limitations. The text description is not intuitive, and it is difficult to correctly grasp the real situation on the spot. Although photos can make up for some intuitive on-site information that is missing in text descriptions, the information is static, and important traces and physical evidence at the scene cannot be observed from various angles. 3D scanning generates a three-dimensi...
