Embodiment Construction

[0026] This embodiment describes the system composition and partial implementation process in detail.

[0027] This virtual multi-camera target tracking video material generation method provided by the present invention constructs a scene such as figure 1 As shown, the target to be tracked 112 is moving in the scene 111, and the cameras 101-105 are respectively located above, in front of, behind, left, and right of the target to track the target picture, and the tracking pictures of 106-110 are generated respectively through the channel transmission to the display terminal . The number of cameras in the example is not limited to five, and the specific number can be selected by the user.

[0028] According to the needs of the research and verification of the target tracking algorithm, the three-dimensional model is selected from the scene database to modularize the customized scene 201. The customized scene can realize the setting of the target environment 202, target behav...

Abstract

The invention relates to a virtual multi-camera target tracking video material generation method. By aiming at situations that research video source materials are in lack and scene changes are insufficient for multi-camera target tracking, the invention utilizes a vision technology to truly simulate a complex environment of the multi-camera target tracking in a real environment by creating a required scene and customizing the attributes of a tracked target and cameras, and even tracking video materials which rarely appear in the reality can be created. The virtual multi-camera target tracking video material generation method favorably simulates problems of specific complex environments, such as shadows, target occlusion, illumination variation, target deformation, texture changes, target generation and disappearing and the like which are not easy to realize in the reality in a target tracking process, and the three-dimensional realization processes of multi-camera calibration, collaborative operation, synchronous calibration, network layout and the like are solved. The frame data of a camera channel is processed to generate a virtual multi-camera target tracking vide, and great help is provided for target tracking algorithm research and verification.

Description

technical field [0001] The invention belongs to the field of video material generation of virtual scenes, and in particular relates to a method for generating virtual multi-camera target tracking video material. Background technique [0002] With the development of video moving target detection and tracking technology, the limited field of view of a single camera cannot meet the requirements of long-term and large-scale tracking of moving targets. Multi-camera multi-target tracking has received a lot of attention in wide-area surveillance scenarios. At present, the research and algorithm verification of multi-camera target tracking is largely limited by video source materials. Due to multi-camera movement and target matching, researchers cannot easily realize the video recording process, and it is difficult to obtain video materials to verify the algorithm. Some specific scenarios such as shadows, target occlusion, target deformation and feature changes cannot be well realiz...
