Problems solved by technology
[0003] However, the current group interaction virtual game supports a small number of people, which is ineffective for group interaction in large-scale scenarios
The monitoring range based on the single-camera tracking method is limited, and it is prone to interference such as occlusion, which leads to tracking failure

Embodiment Construction
[0043] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0044] Such as figure 1 As shown, according to the effective capture distance of Kinect in the Z-axis direction, the Kinect is arranged at a reasonable height (the recommended value is 3.7m, which can basically accommodate users whose height is from 1m to 2m); according to the calibration of each Kinect on the ground The relative position of the rectangular capture area and the position of Kinect in the horizontal direction at the same height make the vertical alignment and horizontal alignment of the rectangular capture areas of each Kinect, and splicing into a large seamless rectangular scene area.
[0045] Such as figure 2 As shown, the user tracking method flow of the Kinect client is mainly divided into two parts: the pre-preparation stage and the post-tracking processing stage respectively. Among them, the pre-preparation stage is mainly to bin...

The invention discloses a system and a method for tracking group users in large-scale scenes on the basis of Kinect networks. The method includes dividing each large-scale scene into a plurality of small regions for a corresponding group interactive game with the large-scale scene according to valid regions of a visual range of each Kinect network; tracking the users in the different regions in real time by the aid of user depth image information captured by the Kinect networks; associating a plurality of user data captured by the different Kinect networks so as to track the users in real time and confirm identification of the users. The system and the method have the advantages that the system is simple and convenient and is easy to operate; the system is convenient and is easy to operate and low in cost; the Kinect networks can be arranged without being accurately measured, and each Kinect network is only responsible for capturing the users in the corresponding valid regions; the visual regions of the Kinect networks do not need to be overlapped on one another, and accordingly the service quantities of user capturing equipment can be reduced to the greatest extent.
Description
technical field [0001] The invention relates to a large-scale scene group user tracking system and method based on the Kinect network. Background technique [0002] With the improvement of the level of social modernization, people's requirements for entertainment and cultural life are getting higher and higher. The virtual reality technology marked by three-dimensional and immersive lifelike output is gradually applied to these fields. Group-based virtual reality games are gradually Favored. "Kinect Sports Conference 2", launched by Microsoft Game Studios in October 2011, includes six new sports that support multiplayer and single-player modes, including tennis, golf, American football, baseball, skiing and darts. The currently popular 7D motion theater has won the favor of young audiences who pursue freshness and excitement. The advanced 7D interactive technology makes curious audiences feel the shock of technology. Many people or even dozens of people watch in front of th...
