Attitude determination and virtual reality roaming method of intelligent machine

Abstract

Disclosed are attitude determination, panoramic image generation and target recognition methods for an intelligent machine. The attitude determination method for the intelligent machine comprises the following steps: defining a local coordinate system; and determining an intelligent machine attitude matrix Rg, wherein Rg is a 3x3 unit orthogonal matrix relative to the local coordinate system and can be obtained through multiple methods according to different sensors inside the intelligent machine. By means of attitude determination of the intelligent machine, multiple applications can be achieved, comprising a virtual reality roaming method for the intelligent machine, multi-vision localization of the intelligent machine, monocular single-point localization of the intelligent machine, panoramic image generation of the intelligent machine, target direction selection in the intelligent machine, real-time video image correction, single-image localization of the intelligent machine, and relative localization among multiple cameras.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a smart machine attitude measurement and a virtual reality roaming method. Background technique [0002] Virtual reality technology allows users to immerse themselves in the virtual or real three-dimensional scene displayed on the display screen of a smartphone, superimposes virtual target labels on it, and prompts interactive information to the user. Traditional 3D virtual scenes, such as digital 3D cities, games and other applications are very mature, but roaming in 3D scenes is mainly through traditional control devices such as mouse, keyboard, rolling ball, etc. The direction of the control device and the actual scene observed cannot be intuitive Correspondingly, the rendering equipment is huge and clumsy, which will bring great inconvenience to the operator and affect the wide application of these three-dimensional digital technologies. Therefore, there is an urgent ne...

Problems solved by technology

[0012] The traditional navigation service is a map navigation service. What the user sees is a map that does not correspond to the posture of the smartphone and the surrounding real scene. The user needs to work hard to associate the real scene with the map to get the correct direction.

[0013] Traditional navigation services navigate based on a 2-dimensional coordinate system composed of latitude and longitude grids, and the earth is treated as a plane composed of latitude and longitude. Because the distance offset corresponding to the same dimension difference ≥ the distance offset corresponding to the longitude difference, the navigation algorithms in different regions need to be The adjustment of the latitude and longitude ratio is only suitable for small areas in the middle and low latitudes, not for the whole world. This method is no longer applicable near the polar regions, and it is very inconvenient for globalization.
