Nvidia patents method to fix warped lines in wide-angle photos

Patent drawing
Patent drawing from the official filing.

Nvidia describes a technique for processing images to reduce visual distortion, particularly in wide-angle shots. The system analyzes the picture to find straight lines and vanishing points, then adjusts the image shape to keep those lines straight instead of curved.

Why it mattersThis could lead to sharper, more natural-looking photos and videos from cameras with very wide lenses, such as those in phones or VR headsets.

In the filing’s own words

In various examples, a visualization of an environment may be generated using a Panini projection that is optimized based on detected scene content. For example, image data of an environment may be perspective projected (e.g., using a rectilinear projection) to generate a reference projection image, which may be analyzed to detect the presence of vanishing points and/or horizontal lines (e.g., in a central region). The image data of the environment may be projected using a Panini projection that is optimized based on distances to detected objects, the absence of a detected vanishing point, and/or the presence of a detected horizontal line to generate a Panini projection image. In some embodiments, vertical compression is applied to the Panini projection image to correct for distortion of horizontal lines (e.g., based on the presence of a detected horizontal line).

What exactly they claim (claim 1)

1. A processor comprising: one or more processing units to: receive image data representing an environment; and generate a visualization of the environment: based at least on a Panini projection of the image data using one or more parameters determined based at least on detected scene content, and using vanishing point detection to determine whether to apply distortion correction.
