SYSTEM AND METHOD FOR CALIBRATION OF MACHINE VISION CAMERAS ALONG AT LEAST THREE DISCRETE PLANES

This invention provides a system and method for generating camera calibrations for a vision system camera along three discrete planes in a 3D volume space that uses at least two (e.g. parallel) object planes at different known heights. For any third (e.g. parallel) plane of a specified height, the system and method then automatically generates calibration data for the camera by interpolating/extrapolating from the first two calibrations. This alleviates the need to set the calibration object at more than two heights, speeding the calibration process and simplifying the user's calibration setup, and also allowing interpolation/extrapolation to heights that are space-constrained, and not readily accessible by a calibration object. The calibration plate can be calibrated at each height using a full 2D hand-eye calibration, or using a hand-eye calibration at the first height and then at a second height with translation to a known position along the height (e.g. Z) direction. 1a vision system camera assembly having a field of view within a volume space;at least one calibration object having calibration features;a calibration process that, with acquired images of the calibration object, performs (a) a first calibration using the calibration object within a first plane of the volume space, and (b) a second calibration using the calibration object within a second plane of the volume space that is separated along an axis from the first plane; andan interpolation/extrapolation process that is associated with the calibration process that receives calibration data from the first calibration and the second calibration and therewith generates calibration data for at least a third plane within the volume space separated along the axis from the first plane and the second plane..

Upon detecting the start of a panning operation, an adder-subtractor applies an offset from an offset change circuit to the output of an HPF (High-Pass Filter) representing the shake amount of an image capturing apparatus to decrease the shake amount. The offset value is set to be larger as the value of shake correction data output from a focal length calculation circuit is closer to the correction limit of a blur correction circuit. Upon detecting the end of the panning operation, the offset value is returned to zero. This invention provides a blur correction apparatus capable of suppressing degradation of a blur correction effect even when in a panning state. 1. A blur correction apparatus comprising:a computation unit configured to compute, based on an output of a shake detection unit, data for correcting image shake;a panning determination unit configured to determine, based on an output of the shake detection unit, whether a panning operation is being done;an offset value generation unit configured to generate an offset value to be subtracted from the data for correcting image shake; anda control unit configured to control a shake correction unit based on an output of the shake detection unit, in order to correct image shake,wherein the offset value is data for returning the shake correction unit approaching a correction limit to a correction center position,wherein, if it is determined by said panning determination unit that a panning operation is being done, said control unit controls the shake correction unit based on data obtained by subtracting the offset value from the data for correcting image shake, andwherein said offset value generation unit generates the offset value so that a first offset value corresponding to a first focal length of an imaging optical system is smaller than a second offset value corresponding to a second focal length of the imaging optical system being smaller than the first focal length.2.
