COLOR BLOCK TAG-BASED VIRTUAL WALL CONSTRUCTION METHOD AND APPARATUS, MAPPING METHOD, MOBILE ELECTRONIC DEVICE

摘要

A color block tag-based virtual wall construction method and apparatus, a mapping method, a mobile electronic device. According to the color block tag-based virtual wall construction method, a color block tag is set directly at the position where it is required to construct a virtual wall, and the feature straight line or feature point of the color block tag is defined; then during the traversal of a room, when obtaining an image comprising a particular color block tag in a wide-angle range of a camera, a mobile electronic device can calculate position information of the virtual wall by means of the predefined feature straight line and feature point, and automatically constructs the virtual wall. The present invention is simple, practical, and highly reliable. In addition, the use of the color block tag implements easy removal and installation, and when a user needs to change the position of the virtual wall or remove the virtual wall, it is only required to tear off the color block tag.
