At the time of occurrence of camera shake, an angular velocity sensor detects an angular velocity. A rotation angle calculator integrates the angular velocity to calculate angle camera shake. A translational acceleration calculator subtracts an internal acceleration caused during operation of a lens unit from a first translational acceleration detected by an acceleration sensor, so as to calculate a second translational acceleration. A translational velocity calculator integrates the second translational acceleration to calculate a translational velocity. A rotation radius calculator calculates a rotation radius based on the angular velocity and the translational velocity. A shake amount calculator calculates a camera shake amount based on the angle camera shake and the rotation radius. An actuator drives a camera shake correction lens in a direction for canceling the camera shake amount.

System and method for extending depth of field for 2d vision system cameras in the presence of moving objects

Номер: US20220014682A1
Автор: Esther Oteo Lozano, Jose Fernandez Dorado, Laurens Nunnink, Pablo Garcia Campos
Принадлежит: Cognex Corp

This invention provides a system and method for enhanced depth of field (DOF) advantageously used in logistics applications, scanning for features and ID codes on objects. It effectively combines a vision system, a glass lens designed for on-axis and Scheimpflug configurations, a variable lens and a mechanical system to adapt the lens to the different configurations without detaching the optics. The optics can be steerable, which allows it to adjust between variable angles so as to optimize the viewing angle to optimize DOF for the object in a Scheimpflug configuration. One, or a plurality, of images can be acquired of the object at one, or differing angle settings, with the entire region of interest clearly imaged. In another implementation, the optical path can include a steerable mirror and a folding mirror overlying the region of interest, which allows different multiple images to be acquired at different locations on the object.
