A stereoscopic camera calibration target includes: first illumination points on a first surface; second illumination points on a second surface, the first and second surfaces being planar, parallel to each other, and spaced from each other; and circuitry that sets a strobe frequency of the first and second illumination points. A method includes: moving a calibration target in front of a stereoscopic camera, the calibration target comprising first points on a first surface and second points on a second surface, the first and second surfaces being planar, parallel to each other, and spaced from each other; capturing, using the stereoscopic camera, an image sequence of the calibration target, the image sequence comprising pairs of left and right images of at least some of the first and second points; determining a calibration value for the stereoscopic camera using the image sequence; and processing the image sequence using the calibration value.

Calibrating stereoscopic cameras

A computer-implemented method for adjusting stereo images includes receiving a video sequence associated with a recorded setting of a stereoscopic camera, the video sequence comprising pairs of left and right images. The method includes processing the pairs of left and right images to reduce influence of a discrepancy between the recorded setting and an actual configuration of the stereoscopic camera.

Adjusting stereo images

A device includes a plurality of vertically aligned pairs of light sources. The device is configured to sequentially illuminate the vertically aligned pairs of light sources. The output illuminating can be captured by a camera having a rolling shutter delay to create an image having a rolling shutter artifact. The image can be analyzed to determine the rolling shutter delay of the camera.

Rolling shutter timing tester

A system includes a computing device that includes a memory for storing one or more computer graphics, and a graphics distorter. The graphics distorter applies a distortion model to the computer graphic to produce a distorted version of the computer graphic, while substantially simultaneously allowing user interactions with the computer graphic. The applied distortion model represents lens distortion.
