Abstract
Disclosed herein are systems and methods for calibrating a stereoscopic imaging device. An example implementation includes receiving, at a processor, a plurality of image pairs from the stereoscopic imaging device and calculating, for each image pair in the plurality of image pairs, a respective row delta value indicative of a deviation along a horizontal axis between the first image captured by the first sensor and the second image captured by the second sensor. The implementation further includes determining a median row delta value based on each respective row delta value and subsequently a set of respective disparities in one or more features in the first image and the second image based on the median row delta value. The method further includes calculating a column delta value and calibrating the stereoscopic imaging device using the median row delta value and the column delta value.
