    • A refrigerator includes a sensing system for detecting multiple physical characteristics of ice cubes in an ice cube storage bin. The system includes a digital image capture device coupled to a digital image analyzing system which captures digital images of the ice cube storage bin intermittently and compares the images to detect the presence of ice clumps. In addition, the digital image analyzing system evaluates the edges, ice size and/or image intensity of the ice cubes in the images in order to determine the presence of stale ice. An algorithm is utilized to estimate the volume of ice within the bin based on the number of pixels in an ice bin image, the number of pixels of the ice within the bin, and a known volume of the ice bin. Notifications for clumped ice, stale ice and ice volume within the bin are sent to a user interface.
    • 冰箱包括用于检测冰块存储箱中的冰块的多个物理特性的感测系统。 该系统包括耦合到数字图像分析系统的数字图像捕获设备,其间歇地捕获冰块存储箱的数字图像,并比较图像以检测冰块的存在。 此外,数字图像分析系统评估图像中的冰块的边缘,冰尺寸和/或图像强度,以便确定陈旧的冰的存在。 基于冰箱图像中的像素数,箱体内的冰的像素数量以及冰箱的已知体积,利用算法来估计箱内的冰量。 垃圾桶内的冰块,陈冰和冰量的通知被发送到用户界面。
