Spatial labeling method based on SLAM

Abstract

The invention discloses a space labeling method based on SLAM. The method comprises the steps of performing two-dimensional mapping on a two-dimensional map subjected to remote labeling; carrying outspace conversion based on an SLAM technology; accurately placing the two-dimensional plane content marked by an expert at the position of the three-dimensional virtual space corresponding to the expert; and finally, rendering the three-dimensional virtual space through glasses equipment. The imaging effect of the human eyes is overlapped with the real scene through the glasses, and finally the effect seen by a user is completely consistent with the position marked by the expert. The change along with the position change of the user is avoided. According to the spatial labeling method based onthe SLAM, the labeling content is converted into a three-dimensional space placement map from a two-dimensional plane labeling map; the three-dimensional space placement map is accurately superposedin a real three-dimensional space, and a labeling target is followed in real time; labeling positions and information can be visually seen; and text or language expressions are omitted.

Description

technical field [0001] The invention relates to the field of labeling methods. More specifically, the present invention relates to a SLAM-based spatial labeling method. Background technique [0002] In daily life or in industrial production, in order to solve some problems that cannot be solved by oneself, the experts are far away, and the remote experts are requested to assist in the operation through video calls. When an expert gives guidance to the other party, some problems or operations may be encountered, and the position may not be accurately described through simple language expressions, and may need to be completed by means of drawing and marking. [0003] Among the existing annotation methods, one is to directly annotate on the top layer of the screen, and the annotation content will never have any interaction with the real environment; the other is to annotate the content following the movement of the camera, but there are differences between the annotation posit...

Problems solved by technology

When experts give guidance to the other party, they may encounter some problems or operations, which may not be able to accurately describe the position through simple language expressions, and may need to be completed by means of drawing and marking

[0003] Among the existing annotation methods, one is to directly annotate on the top layer of the screen, and the annotation content will never have any interaction with the real environment; the other is to annotate the content following the movement of the camera, but there are differences between the annotation position and the position marked by the expert. big error
