Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces an AR virtual projector as an intermediary element that bridges the gap between real space and simulation data. The virtual projector is superimposed on the captured space image, allowing accurate visualization of projector placement and projection areas without requiring complex physical prototypes or sophisticated measurement equipment.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system transitions from 2D planar measurements to 3D spatial visualization by using AR to render the virtual projector and its projection areas within the captured 3D space. This dimensional enhancement allows accurate representation of projector placement positions, projection distances, and screen areas without increasing physical device complexity.

Inventive Principle:

Solution Approach 1:

The system implements feedback by allowing users to interactively adjust the virtual projector's position, orientation, and parameters within the AR environment. Users can move the virtual projector to different locations, and the system automatically recalculates and displays the corresponding projection areas and screen positions, providing real-time feedback on placement accuracy and enabling precise determination through iterative adjustment.

AI summary

A method for simulating setting of a projector by augmented reality (AR) includes: activating an AR application on a terminal device; performing, through an image capturing element of the terminal device, dimension measurement on a space where a projector is to be disposed to obtain a space dimension; selecting a placement reference point of the projector and a display reference point of a projection picture; generating, according to the space dimension, the placement reference point, and the display reference point, a simulation picture on the terminal device when the projector projects the projection picture in the space; adjusting the projection picture and/or the projector in the simulation picture to generate an adjusted simulation picture; and comparing the adjusted simulation picture with projector parameter data of projector models to recommend at least one projector model to a user for selection or inputting, by the user, a custom projector model.
