VARIED DEPTH DETERMINATION USING STEREO VISION AND PHASE DETECTION AUTO FOCUS (PDAF) - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240223715 titled 'VARIED DEPTH DETERMINATION USING STEREO VISION AND PHASE DETECTION AUTO FOCUS (PDAF)
The patent application describes a system that uses stereo vision and phase detection auto focus (PDAF) to determine varied depths in images.
- Stereo vision extracts three-dimensional information from digital images by using two optical sensors displaced horizontally to capture different views of a real-world environment.
- Triangulation is used to determine the relative depth of objects in the images by comparing their positions in the two images.
- Matching objects in the images are used, along with the known orientation of the optical sensors, to estimate the depth of the objects.
Potential Applications: - Autonomous vehicles for accurate depth perception - Robotics for object recognition and manipulation - Augmented reality for realistic depth rendering
Problems Solved: - Accurate depth determination in digital images - Enhanced object recognition in various applications - Improved spatial awareness in technology

Original Abstract Submitted
disclosed are systems, methods, and non-transitory computer-readable media for varied depth determination using stereo vision and phase detection auto focus (pdaf). computer stereo vision (stereo vision) is used to extract three-dimensional information from digital images. to utilize stereo vison, two optical sensors are displaced horizontally from one another and used to capture images depicting two differing views of a real-world environment from two different vantage points. the relative depth of the objects captured in the images is determined using triangulation by comparing the relative positions of the objects in the two images. for example, the relative positions of matching objects (e.g., features) identified in the captured images are used along with the known orientation of the optical sensors (e.g., distance between the optical sensors, vantage points the optical sensors) to estimate the depth of the objects.
