A mixed reality recognition association method and device

Abstract

The invention discloses a mixed reality recognition association method and device. The method includes: detecting a recognition disk, determining the location of the recognition disk as the recognition background range; detecting that a recognition body with a unique recognition mark enters the recognition background range, and displaying a real scene picture At the same time, the virtual object associated with the identification mark is displayed at the position of the identification body; when the identification body is blocked and the occlusion part exceeds the preset occlusion threshold, the identification mark of the identification body that is blocked and the occlusion part exceeds the preset occlusion threshold is taken as For the occluded identification mark, start the occlusion timing for the occlusion identification mark. During the occlusion time, keep the virtual object associated with the occlusion identification mark. If the identification body corresponding to the occlusion identification mark has not been detected beyond the occlusion time, it will be cancelled. Display all virtual objects, otherwise keep all virtual objects. The present invention avoids the situation that the virtual object is displayed unstable or even disappears when the identification body is blocked due to misoperation.

Description

technical field [0001] The present invention relates to the technical field related to mixed reality, in particular to a method and device for identifying and associating mixed reality. Background technique [0002] Mixed reality technology, such as Mixed reality (MR) or Augmented Reality (AR), is a further development of virtual reality technology. This technology introduces real scene information into the virtual environment to create a bridge between the virtual world, the real world and users. An information loop for interactive feedback to enhance the realism of the user experience. [0003] In the mixed reality technology, an identification body, such as a specific pattern or a specific entity, needs to be identified. The detection device detects the identification body, and then a virtual picture can be formed in the identification body. [0004] However, in the existing mixed reality technology, the recognition body is only used as a sign. After the detection device...

Problems solved by technology

[0006] Based on this, it is necessary to provide a mixed reality technology for the technical problem that the recognition of the recognition body is unstable or even interrupted when the recognition body is occluded, which leads to the inability to interact with the recognition body in the mixed reality technology environment.
