Abstract

The invention provides a calibration method for a head-mounted device and the head-mounted device. The calibration method comprises the following steps: detecting eyeball position information of a user; and adjusting the position of at least one display screen according to the eyeball position information of the user. According to the calibration method provided by the embodiment of the invention, by obtaining the eyeball position information of the user, and comparing the deviation between the eyeball position of the user and the position of the display screen, the position of the display screen is adjusted, an adjusting result adapts to the eyeball position of the user, the pertinence is strong, the personalized needs of the user are well met, and the user experience is enhanced.

Description

technical field [0001] The present invention relates to the technical field of smart devices, in particular to a calibration method for a head-mounted device and the head-mounted device. Background technique [0002] Head-mounted devices can be integrated with cameras and control chips to form smart head-mounted devices (such as smart glasses), providing users with rich personalized functions and information. With the development of science and technology, the practicability and entertainment of head-mounted devices have been continuously enhanced, and are now being gradually applied to various fields such as people's work and life. However, the images displayed by head-mounted devices are not accurate enough, and phenomena such as graphic distortion and information shift often occur. Current auto-calibration technologies for head-mounted devices usually use laser sensors to achieve automatic screen calibration based on the position and distortion information of the head-mo...
