SKY DETECTION SYSTEM AND METHOD USED IN IMAGE COLLECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a sky detection system and method used in an image collection device.SOLUTION: The sky detection system includes: an image collection unit that collects information of a color image; a color-feature extraction unit that extracts a color feature of each pixel from the collected image; a distance measurement unit that measures a distance between the pixels of the collected image and a lens in each pixel; a first classification unit that classifies the pixels of the collected image as either a sky pixel or a non-sky pixel in each pixel based on the color feature; and a second classification unit that further classifies the pixels of the collected image as either the sky pixel or the non-sky pixel based on a result of the distance measurement unit and a result of the first classification unit.
