Abstract

The invention discloses a virtual coordinate system construction method and device, terminal equipment and a readable storage medium. When the virtual coordinate system is constructed, the first coordinates of the first mark point and the second coordinates of the second mark point on the mark rod in the imaging picture of the mark rod acquired by an image sensor are determined, then a first coordinate system of the visual sensor angle of view is constructed according to the first coordinates and the second coordinates and a second coordinate system of the display screen angle of view is constructed according to the third coordinates of a plurality of vertical contact positions of the mark rod on the display screen acquired from the display screen, then the relative relationship between the first coordinate system and the second coordinate system in the three-dimensional space is calculated according to the principle of homography transformation and finally a virtual coordinate systemwhich can realize high-precision tracking of the operation action and accurately calibrate the coordinates of the position of the interactive device in the three-dimensional space can be constructed according to the calculated relative relationship and thus the human-computer interaction effect can be greatly enhanced.

Description

Technical field [0001] The present invention relates to the technical field of human-computer interaction, in particular to a method, device, terminal equipment and readable storage medium for constructing a virtual coordinate system. Background technique [0002] With the rapid development and widespread popularity of computer technology, human-computer interaction technology has become a new research field. [0003] Human-computer interaction technology refers to the technology that realizes the dialogue between human and computer in an effective way through computer input and output devices. In human-computer interaction technology, virtual reality technology is an important branch of human-computer interaction technology. Virtual reality technology mainly determines the mapping relationship between virtual reality and the real world by relying on real-time calculation of various posture information in the three-dimensional space, and The spatial attitude of the target to be re...
