CHECKERBOARD CORNER DETECTION METHOD AND DEVICE

摘要

The present application relates to the field of computer vision techniques, and discloses a checkerboard corner detection method. Said method comprises: detecting, by using a haar feature, a checkerboard image, so as to obtain a haar feature value; processing the haar feature value into a feature value distribution image, the haar feature value distribution image comprising a dot-shaped region; and calculating a central position of the dot-shaped region, so as to obtain corners. Said method increases the accuracy of checkerboard detection. The present application further discloses a checkerboard corner detection device, a computer-readable storage medium and a computer program product.
