Correction of Lens-Distortion for Real-Time Image Processing Systems
نویسندگان
چکیده
This paper presents the design of a real-time imaging system, with incorporated the correction of lens-distorted images. It may be used in medical applications (e.g. real-time X-ray image intensifiers), industrial robot vision products or consumer electronics. The system contains two different VLSI-circuits: a transformer and an interpolator. The transformer calculates an address that points to a pixel in the input image. Since this address hardly ever is an exact pixel position, a cubic-spline interpolator is used to calculate the pixel-intensity at the desired position.

Real-time geometric lens distortion correction using a graphics processing unit
Optical imaging systems often suffer from distortion artifacts which impose important limitations on the direct interpretation of the images. It is possible to correct for these aberrations through image processing, but due to their calculation-intensive nature, the required corrections are typically performed offline. However, with image-based applications that operate interactively, real-time...
متن کاملReal-Time Restoration of Lens Distorted Images by Digital Image Processing
This paper describes a real-time system for image acquisition, where images are corrected for lensdistortion. Three kinds of distortion can be corrected by the system: barrel, pincushion and pocket-handkerchief. Applications can be found in very high light-efficient systems where lenses with a large numerical aperture produce barrelor pincushion distortion. Examples are medical X-ray systems, w...
