Cog3DCalibrationFeatureExtractorBase Execute Method (List List ICogImage  )Cognex VisionPro 9.8
Extract features from a set of calibration images, acquired from one or multiple cameras over different calibration plate poses. The images are organized in a List, indexed by calibration plate pose. Each item in the list is a List of images, indexed by camera. It is expected that the fiducial defining the calibration plate's origin is within the field of view. The feature extraction is done by calling the Execute( ICogImage ) method for each calibration image. The Execute( ICogImage ) method will be invoked on multiple threads if the IsThreadSafe property is true. The FeaturesExtracted event is fired after the featues are extracted from each image.

Parameters

images
Type: System.Collections.Generic List List ICogImage  
A doubly indexed list of the calibration images, indexed first by calibration plate pose, then by camera.

Return Value
