Embodiment approach

[0115] In one embodiment, the method also includes:

[0116]Extract the SURF feature points from the real scene image, and determine the feature points matching the real target template from the feature points, so as to identify the real target, calculate the translation matrix of the real target and the virtual model relative to the camera, and then calculate the real target The translation of the target and the virtual model relative to the camera, by comparing the translation of the real target and the virtual model relative to the camera, the occlusion relationship between the real target and the virtual model is determined, and the corresponding part of the occluded object is hidden.

[0117] In one embodiment, the fusion of the virtual scene and the real scene image to obtain the restored scene picture of the augmented reality includes:

[0118] The edge image is obtained by performing edge detection on the real scene image, and the occlusion area mask map is obtained by...

Abstract

This application discloses a three-dimensional augmented reality method for scene restoration of accidents and police situations. Firstly, an image of the real scene is obtained, and then artificial marks are identified from the image of the real scene, and the position of the virtual model in the virtual scene is calculated, and then obtained and Manually mark the corresponding virtual 3D static model and / or virtual 3D dynamic model, place the model at the corresponding virtual model position in the virtual scene, and finally fuse the virtual scene with the real scene image to obtain the restored scene picture of augmented reality. Restore the accident process through augmented reality technology to help relevant personnel understand the accident situation correctly and quickly and make judgments.

Description

technical field [0001] The present application relates to the technical field of accident handling, in particular to a three-dimensional augmented reality device and method for restoration of accident and police scenes. Background technique [0002] In the daily life of human beings, some accidents inevitably occur, such as traffic accidents, and sometimes criminal cases such as burglary. [0003] When a traffic accident occurs on the road, the traffic control department will send traffic police to the scene to investigate and determine the responsibility and damage. However, for some traffic accidents with complex cases, when the traffic police arrive at the scene to determine the responsibility and damage, because the accident has already occurred, it is sometimes difficult for the traffic police to quickly and accurately judge the occurrence of the accident, and it is difficult to immediately report to the party responsible for the accident. Justly punish and close the c...
