Patent number: 11966810Abstract: 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.Type: GrantFiled: October 31, 2019Date of Patent: April 23, 2024Assignee: Cognex CorporationInventors: Laurens Nunnink, Bennet Heidekorn, Jens Ruetten, Martijn Lambertus Peter Visser, Carl W. Gerst, III, William Equitz, Matthew D. Engle

Patent number: 11323629Abstract: This invention provides a single-camera vision system, typically for use in logistics applications, that allows for adjustment of the camera viewing angle to accommodate a wide range of object heights and associated widths moving relative to an imaged scene with constant magnification. The camera assembly employs an image sensor that is more particularly suited to such applications, with an aspect (height-to-width) ratio of approximately 1:4 to 1:8. The camera assembly includes a distance sensor to determine the distance to the top of each object. The camera assembly employs a zoom lens that can change at relatively high speed (e.g. <10 ms) to allow adjustment of the viewing angle from object to object as each one passes under the camera's field of view (FOV). Optics that allow the image to be resolved on the image sensor within the desired range of viewing angles are provided in the camera lens assembly.Type: GrantFiled: June 29, 2020Date of Patent: May 3, 2022Assignee: Cognex CorporationInventors: Laurens Nunnink, Esther Oteo Lozano, Richard Reuter, Matthew D.

Patent number: 10445544Abstract: 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.Type: GrantFiled: January 8, 2018Date of Patent: October 15, 2019Assignee: COGNEX CORPORATIONInventors: Laurens Nunnink, Carl W.

Patent number: 9734372Abstract: The described mobile device for optically reading a machine-interpretable code, used for example in an order picking system for consumer and/or consumable goods, includes a head-mountable scanner with a code reader and a control unit controlling the head-mounted scanner to switch the code reader between a detection mode and a reading mode. In the detection mode, the code reader operates in a low power mode sufficient to detect the presence of a machine-interpretable code. The control unit switches the code reader into the higher-powered reading mode when the code is detected to optically read the code. A wireless communication device may also be provided to wirelessly transmit information corresponding to the scanned code to a remote receiving unit for storage and/or data processing.Type: GrantFiled: June 2, 2014Date of Patent: August 15, 2017Assignee: OCADO INNOVATION LIMITEDInventors: Lars Sverker Ture Lindbo, Paul Clarke, Matthew D.
