Crime scene graph generation method and system based on three-dimensional reconstruction and storage medium

Abstract

The invention discloses a crime scene graph generation method and system based on three-dimensional reconstruction, and a storage medium, and the method comprises the steps of carrying out the three-dimensional scanning of a crime scene to obtain three-dimensional data, and building a three-dimensional live-action model of the crime scene through combining the three-dimensional data with a presetartificial intelligence algorithm; and obtaining a crime scene graph according to the three-dimensional live-action model, wherein the crime scene graph comprises a plane scale graph and/or a three-dimensional scale graph. According to the invention, after the crime scene is scanned and the three-dimensional live-action model is established, the plane scale map and the three-dimensional scale mapof the crime scene are directly obtained according to the three-dimensional live-action model, manual drawing is not needed, the drawing cost is greatly reduced, meanwhile, errors caused by manual drawing are avoided, and the drawing quality is improved. Besides, details of a crime scene can be recorded in detail through the scale map obtained through the three-dimensional live-action model, the drawing scientificity is improved, and the invention can be widely applied to the technical field of data processing.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method, system and storage medium for generating a crime scene map based on three-dimensional reconstruction. Background technique [0002] A crime scene investigation is the starting point for a case investigation. The fixation, restoration and reconstruction of the crime scene must fully and objectively reflect the real situation of the scene. For a long time, the on-site investigation personnel are still affected by the hardware equipment, technical conditions and professional level, and still use manual drawing, on-site photos, PPT and other forms to analyze and study the case. [0003] At present, when drawing the crime scene, the main method of manual drawing is to first carry out the size survey, and after the scale conversion, draw the scene structure diagram to show the structure layout of the scene. In this way, it takes professional drawing personnel to spen...

Problems solved by technology

[0003] At present, when drawing a crime scene, the manual drawing method is mainly used. First, the current size survey is carried out, and after the scale conversion, the scene structure diagram is drawn to show the structural layout of the scene. In this way, it takes a lot of professional drawing personnel It takes less time to draw pictures; if the manually measured data is wrong, it may also cause errors in the structural drawing

In addition, this Figure 1 Generally, it is a black and white line drawing, which simply outlines the structure of the site, and omits the detailed pictures inside the building, which is not conducive to objectively reflecting the situation of the site
