Title:
POSITION ADJUSTING METHOD AND SYSTEM FOR AERIAL IMAGE FORMING PROJECTION PATTERN
Document Type and Number:
WIPO Patent Application WO/2023/236716
Kind Code:
A1
Abstract:
A position adjusting method and system for an aerial image forming projection pattern, the method comprising: collecting an angle parameter and a position parameter of a test object within a preset range, and using the collected angle parameter and position parameter as target values (S1); according to the position of a current aerial image forming projection pattern, obtaining a corresponding angle parameter and position parameter as current values (S2); calculating corresponding difference values according to the target values and the current values (S3); and obtaining, according to the difference values, parameter values required for adjustment of a driving motor used for controlling the position adjustment of the aerial image forming projection image, and according to the parameter values, adjusting the driving motor (S4). The position of an aerial image forming projection pattern can be adaptively adjusted, so as to be suitable for the heights of different users and the postures different users have during use, and better meet observation viewpoint requirements of the users; and the intelligence level is further improved.
