AI Technical Summary

Problems solved by technology

The photographic method is widely used, but because the photos are static, there is no interaction between the scene and the user. For the positional relationship between more complex objects, some text annotations must be made, but the correspondence between text annotations and photos Relationships are more likely to be confused

Embodiment Construction

[0035] The system includes main server (1), communication module (2), image collector (3), mobile terminal (4), operation terminal (5) such as Figure 10 As shown, the main server (1) is connected to the operation terminal (5) through the communication module (2). upload photos to the server. The mobile terminal (4) queries part of the case information through the wireless network, and uploads the case information to the main server (1), and the main server completes the data management and image rendering of the entire system.

[0036] The system server adopts IBM System x3850 X5 server. In order to ensure the high efficiency of operation, orale is selected as the database support for the database, such as Figure 9 As shown, the full-true dynamic 3D reconstruction system includes scene restoration management module, system management module, and element management parts such as scenarios and event scenes figure 1 shown.

Abstract

The invention relates to a case and event scene all-true dynamic 3D representation method and reconstruction system. The method comprises the following steps: collecting scene information, using a camera for collecting scene image data, labeling case and event information, conducting comparison on and extracting the image data, the case information and elements prestored in an element library, then respectively conducting indoor scene restoration, outdoor scene restoration, full scene restoration and geographic reduction, and conducting outputting. 3D scene pictures and animations are combined with sound and texts, so that different 3D virtual scenes and multimedia video materials can be generated for various users, and digital multimedia information can be analyzed, stored, exchanged and transmitted inside a compact disc or on the internet.

Description

technical field [0001] The present invention relates to a real dynamic 3D reconstruction system for on-site cases and event scenes. It uses ground LOD and Frustum Culling technology to optimize and cut scenes, and uses Octree technology for collision detection, so that the operating efficiency can be kept as stable and smooth as possible. s level. technical background [0002] The reconstruction of the crime scene is of great importance to the detection of criminal cases. Due to the particularity of the crime scene, many scenes are not suitable for long-term storage. Therefore, in order to record the original appearance of the scene, it is necessary to record the characteristics of the scene by means of drawing, photography, and video recording. The method of drawing is only suitable for investigators with rich experience and strong drawing skills, and they must visit the scene in person and have careful observation and memory of the scene. The photographic method is widel...
