Perspective Correction With Depth Clamping - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240233205 titled 'Perspective Correction With Depth Clamping
The method described in the patent application involves performing perspective correction of an image captured by an image sensor in a device with processors and memory.
- Capturing an image of a physical environment using the image sensor.
- Obtaining depths associated with pixels of the image.
- Generating a clamped depth map based on the depths, with values above a threshold.
- Transforming the image based on the clamped depth map and user perspective to create a display image.
- Displaying the corrected image on a display.
Potential Applications: - Augmented reality applications - Virtual reality systems - Image editing software - Surveillance systems - 3D modeling tools
Problems Solved: - Correcting perspective distortion in images - Enhancing user experience in AR/VR environments - Improving accuracy in depth mapping
Benefits: - Enhanced visual quality in images - Improved user immersion in virtual environments - Precise depth perception in images - Accurate perspective correction
Commercial Applications: Title: "Advanced Image Correction Technology for AR/VR Systems" This technology can be utilized in various commercial applications such as: - AR/VR gaming - Architectural visualization - Medical imaging - Security and surveillance systems - Entertainment industry for special effects
Questions about Perspective Correction Technology: 1. How does perspective correction technology improve the user experience in augmented reality applications? - Perspective correction technology ensures that virtual objects align correctly with the physical environment, creating a more realistic and immersive AR experience.
2. What are the key differences between perspective correction in 2D images and 3D environments? - Perspective correction in 2D images involves adjusting angles and proportions, while in 3D environments, it also considers depth and spatial relationships for accurate rendering.
Original Abstract Submitted
in one implementation, a method of performing perspective correction of an image is performed by a device including an image sensor, a display, one or more processors, and non-transitory memory. the method includes capturing, using the image sensor, an image of a physical environment. the method includes obtaining a plurality of depths respectively associated with a plurality of pixels of the image of the physical environment. the method includes generating a clamped depth map of the image of the physical environment based on the plurality of depths, wherein each element of the clamped depth map has a depth value above or equal to a depth threshold. the method includes generating a display image by transforming, using the one or more processors, the image of the physical environment based on the clamped depth map and a difference between a perspective of the image sensor and a perspective of a user. the method includes displaying, on the display, the display image.
