Cloud computing-based calibration method, apparatus, electronic device and computer program product

TL;DR: In this article, a cloud computing-based OSTHMD calibration method was proposed, where the alignment data of the current user and the conversion parameter of the OSTHD were used to reduce the time and energy consumption of the SPAAM calibration.

Abstract: A cloud computing-based calibration method, a device, an electronic device, and a computer program product. The method comprises: determining an existing conversion parameter G, the conversion parameter G being a conversion parameter from a tracking coordinate system to a virtual coordinate system produced by calibration of an OSTHMD on the basis of SPAAM; acquiring alignment data of a current user; and computing, on the basis of the alignment data of the current user and of the conversion parameter G, a conversion parameter G' from the tracking coordinate system to the virtual coordinate system of the current user. In the present application, the calibration of the OSTHMD of the current user can be completed by utilizing existing calibration data, the need to perform a full SPAAM calibration with respect to the current user is obviated, and only a small amount of alignment data needs to be collected, thus simplifying operation and reducing the time spent.
