Produce and Non-produce Verification Using Hybrid Scanner
First Claim
Patent Images
1. Apparatus for verifying whether an item is produce or not comprising:
- a scale utilized to weigh produce items;
a camera for generating an image of the item when the item is placed within a field of view of the camera on the scale;
an illumination mechanism for selectively illuminating the field of view of the camera;
a produce verification model database storing data for produce items to be verified; and
a processor for controlling the camera and the illumination mechanism, and retrieving a model for a particular item of produce to be weighed from the produce verification model database, wherein the processor controls the camera to capture image data for the item;
extracts features from the captured image data;
fits the extracted features to a retrieved model for the particular item of produce; and
verifies the item as produce or not based upon the fit of the extracted features to the retrieved model.

Abstract
Approaches to produce verification are addressed which may be suitably employed in conjunction with a low resolution image scanner. Features, such as lines, corners, text, texture, edges and the like are extracted and compared with features for an identified item or evaluated to determine if the features collectively are indicative of a produce item or a non-produce item.

11. Apparatus for categorizing an item as produce or non-produce comprising:
-
a camera for generating an image of the item when the item is placed within a field of view of the camera on the scale; a categorization database storing data for produce and non-produce items to be categorized; and a processor for controlling the camera, and retrieving product categorization criteria from the categorization database, wherein the processor controls the camera to capture image data for the item;
extracts features from the captured image data;
applies a retrieved categorization criteria; and
categorizes the item as produce or non-produce based upon the application of the categorization criteria to the extracted features from the captured image data. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
