Positioning method and handle

Abstract

An embodiment of the invention relates to the technical field of virtual reality and discloses a positioning method and a handle. In the invention, a method for positioning a lamp group-equipped object to be positioned comprises the following steps: identification codes corresponding to all lamps in a lamp group are obtained; position information of all lamps in the lamp group is determined according to all the identification codes; when position information of one lamp is determined, N prestored models are tested via an identification code, and a model corresponding to the identification code is determined; according to position information which corresponding to the models in a one-to-one manner, the position information of the lamp corresponding to the identification code is determined, N is a natural number greater than one, and a position of the object to be positioned can be determined via three dimensional attitude estimation based on position information of all the lamps. Via the positioning method and the handle provided in the invention, a problem that codes are difficult to identify due to luminance codes which are not obvious can be solved, and effects of one side stereoscopic visual sense can be exerted.

Description

technical field [0001] The embodiment of the present invention relates to the field of virtual reality technology, and in particular to a positioning method and a handle. Background technique [0002] Virtual reality (Virtual Reality, referred to as VR) technology is a new comprehensive information technology emerging at the end of the 20th century. It is an advanced and digital human-machine interface technology. The operating environment and the immersive experience brought to people will fundamentally change the boring, blunt and passive status quo between people and computers, and create a new research field for human-computer interaction technology. With the development of VR technology Development, the handle used to realize the exchange with virtual goods has also received extensive attention. [0003] In the prior art, the interaction between the handle and the virtual object is mainly realized by multiplexing the ordinary color camera on the VR glasses with the spe...

Problems solved by technology

[0004] However, in the process of realizing the present invention, the inventors have found that at least the following problems exist in the prior art: in the prior art, the coding is usually analyzed frame by frame and compared one by one, but this method may cause problems due to the The brightness change is not obvious, so that it cannot be extracted as an effective code, and it cannot be recognized as an effective code, and the monocular stereo vision based on the Hamming code (or other codes) will change the brightness of the LED due to the influence of the angle or speed of movement. Causes the code to be difficult to effectively identify, which makes it impossible to accurately determine the position of the handle
