Abstract
This invention provides a vision system camera assembly and method for using the same that employs a light-field camera with an associated vision system image sensor and overlying microlens optics to acquire images of a scene. The camera generates a light field allowing object features at varying depths of field to be clearly imaged in a concurrent manner. In an illustrative embodiment a vision system, and associated method of use thereof, which images an object or other subject in a scene includes a vision system camera with an optics assembly and a light field sensor assembly. The camera is constructed and arranged to generate light field image data from light received through the optics assembly. A light field process analyzes the light field image data and that generates selected image information. A vision system processor then operates a vision system process on the selected image information to generate results therefrom.
