摘要： This invention provides a field of view expander (FOVE) removably attached to a vision system camera having an image sensor defining an image plane. In an embodiment the FOVE includes first and second mirrors that transmit light from a scene in respective first and second partial fields of view along first and second optical axes. Third and fourth mirrors respectively receive reflected light from the first and second mirrors. The third and fourth mirrors reflect the received light onto the image plane in a first strip and a second strip adjacent to the first strip. The first and second optical axes are approximately parallel and a first focused optical path length between the scene and the image plane and a second focused optical path between the image plane and the scene are approximately equal in length. The optical path can be rotated at a right angle in embodiments.

摘要： A system and method for communicating at least one of updated configuration information and hardware setup recommendations to a user of an ID decoding vision system is provided. An image of an object containing one or more IDs is acquired with a mobile device. The ID associated with the object is decoded to derive information. Physical dimensions of the ID associated with the object are determined. Based on the information and the dimensions, configuration data can be transmitted to a remote server that automatically determines setup information for the vision system based upon the configuration data. The remote server thereby transmits at least one of (a) updated configuration information to the vision system and (b) hardware setup recommendations to a user of the vision system based upon the configuration data.

摘要： This invention provides a vision system camera assembly that includes an optics and illumination module that is removably attached thereto, and that is arranged to project illumination along an optical axis of the imager. This arrangement allows for short exposure time and a short working distance from an imaged scene/surface under inspection. A semi-reflecting mirror turns a structured illumination beam from an illumination axis onto the optical axis while allowing light from the imaged scene to pass through the mirror and into the imager optics. The front end of the module contains a collimating optics that causes a collimated beam from the mirror to strike the surface at various off-axis angles. The collimating optics can include a telecentric lens assembly that can comprise a pair of stacked lenses having a perimeter that is equal to or greater than the area of interest on the surface.

摘要： This invention provides a module for a handheld device. The module includes an imager with optics and image acquisition/processing processors that provide high speed acquisition and handling of acquired image data—such as IDs. The acquired image data is processed by the device processor using a module application that resides within the device. The module includes indicators and/or alarms that can indicate success in reading an ID. A removable retaining component mounts within the module's base portion and carries the device. The retaining component (either a top cover and gasket or subframe) varies to accommodate different devices. The base portion includes appropriate ports to enable optical transmission to, for example, cameras and illuminators so that various native functions of the device can be employed as desired. The base portion also houses a battery and charging assembly e.g. and inductive charging unit. A grip handle/trigger is optionally provided to the base portion.

摘要： This invention provides a system for separating a field of view (FOV) of a scene imaged by a vision system camera assembly, in which a separating mirror assembly redirects a first optical path of at least a first optics with respect to at least a first image sensor in the camera assembly. A first reflecting assembly redirects the first optical path from the separating mirror toward a first FOV. The first optical path is extended free of splitting the image. The separating mirror assembly redirects a second optical path of a second optics with respect to a second image sensor in the camera assembly. A second reflecting assembly redirects the second optical path from the separating mirror toward a second FOV. The second optical path is extended free of splitting the image projected from the scene on the second image sensor.
