A method is provided for analysing images (24a) of bulk material (12), such as harvested crop material using a camera (11) for taking a series of multipixel images (24a) of samples of the bulk material (12). The taken images are processed electronically for determining therefrom properties of the bulk material. The invention provides for detecting one or more errors in the series of pixel images (24a), comprising the substeps of:
a) monitoring the reflectance of one or more of the pixels during sequential processing of each image (24a) and,
if the reflectance value of a said pixel is invariant or substantially invariant in more than a predetermined number of consecutive said images,
b) identifying an error. |
