Wearable Display Peripheral Pose Positioning with Structure Light Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable display devices face challenges in accurately determining the pose of peripherals due to reliance on infrared light balls, which hinder miniaturization and increase costs, and are limited by field of view and signal attenuation issues.
Innovation Solution
A method and apparatus that projects structure light onto real objects, using cameras to determine the pose of peripherals relative to the display host, eliminating the need for multiple infrared light balls and simplifying peripheral structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If infrared light balls are installed on the peripheral to determine pose, then positioning accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the infrared light balls from the peripheral device and relocates them to the helmet. This allows the peripheral to be simplified while maintaining positioning capability, as the helmet (which has more space and power resources) performs the light emission function instead.
Solution Approach 2:
The helmet is given multiple functions: it not only provides visual display but also serves as the infrared light source for positioning the peripheral. This multi-functionality reduces the need for separate components in the peripheral device.
2Measurement precision
If multiple infrared light balls are installed on the peripheral, then positioning accuracy is improved, but miniaturization is hindered
Solution Approach 1:
The infrared light balls are extracted from the peripheral and placed on the helmet, enabling the peripheral to be miniaturized while retaining positioning functionality through the helmet's observation system.
3Measurement precision
If infrared light balls are used for positioning, then pose determination is achieved, but field of view and signal attenuation limit the solution
Solution Approach 1:
Instead of having the peripheral emit infrared light for the helmet to observe, the invention inverts the approach: the helmet emits infrared light and the peripheral (with its camera) observes the illuminated infrared light balls. This inversion expands the field of view and reduces signal attenuation issues.
