摘要
This invention relates to a system and method for detecting the curved surfaces of fruit using a flash and camera system and automated image analysis. Lighting upon fruit is controlled, with a flash or multiple flashes positioned beside the camera illuminate the fruit. The flash causes a strong specular reflectance at the center of curved fruit (such as apples, grapes, or avocados, among others). From this point of specular reflectance, pixel intensity decreases steadily toward the edges of curved fruit. The method searches the images to find points of specular reflectance surrounded by curved shaded regions belonging to the curved fruit and can detect fruit of various sizes and scales within image.
